Arakaki, Chairman and Members of the County Council County of Hawaii 25 Aupuni Street Hilo, HI 96720 Deaz Chairman Arakaki and Members: State Land Use Boundary Amendment Application (SLU 98-9) Request: Agricultural to Urban Change of Zone Application (REZ 98-26) Request: A-20a to MG-IOa Applicant: Hawaii Electric Light Co., Inc. Tax Map Key• 1-6-3.93 The Planning Commission, after a duly held public hearing on January 22, 1999, voted to recommend for your approval the proposed legislative bills to change the State Land Use district from an Agricultural to Urban District and the district classification from Agricultural (A-20a) to General Industrial (MG-l0a) for approximately 10.5 t acres of land. The property is located approximately one mile east of the Keaau Town Center at the end of Milo Street, at the vicinity of the former Puna Sugar Company Mill site at Keaau, Puna, Hawaii. The Commission concurs with the following findings as recommended by the Planning Director: State Land Use Boundary Amendment The approval of the reclassification from the State Land Use Agricultural to the Urban District will not be violative of Section 205-2, Chapter ZOS, Hawaii Revised Statutes, nor will the reclassification actions be inconsistent with the Hawaii Land Use Commission Rules, the Hawaii State Plan and the County Generai Plan. The Hawaii Electric Light Company, Inc. (HELCO) is requesting to redesignate the subject property from Agricultural to Urban, to legitimize the existing Puna Generating Station. This power plant was originally approved through a Special Permit in 1988 and existed as an accessory use to Puna Sugar Mill operations prior to their closing. According to the Hawaii Land Use Commission Rules, one of the standards for considering an azea for urban reclassification is that "In determining urban growth Honorable James Y. Arakaki, Chairman and Members of the County Council Page 2 for the next ten yeazs, or in amending the boundary, land contiguous with existing urban azeas shall be given more consideration than non-contiguous land, and pazticularly when indicated for future urban use on state or county general plans." The project site conforms to this standard as it is designated Industrial on the County General Plan and has been in industrial-related uses for the past 20 yeazs, The property is also situated within the vicinity of existing urban designated lands surrounding Keaau Town. These urban lands include the existing residential neighborhood along and to the south of Milo Street and along the Old Volcano Road (west of the subject property), which are primarily in residential uses. In addition, a section of the adjacent pazcel to the southwest, TMK: 1-6-03:portion of 5 (James McCully} recently secured a State Land Use Boundary Amendment from Agricultural to Urban and a Change of Zone from ML-20a to MCX-20a. Furthermore, back in July 1994, the State Land Use Commission approved a petition filed by the Office of State Planning for boundazy amendment from Agricultural to Urban District for approximately 660 acres of lands surrounding Keaau Village, which are owned by W. H. Shipman, Ltd. The objective of the redesignation was to establish an urban core in the Puna District to service the growing population. One of the urban subareas is located immediately southwest of the subject property. The reclassification action would also achieve the following goals, objectives and/or policies articulated in the Hawaii State Plan: * A strong, viable economy, characterized by stability, diversity and growth that enables the fulfillment of the needs and expectations of Hawaii's present and future generations. * Increased and diversified employment opportunities to achieve full employment, increased income and job choice, and improved living standards for Hawaii's people. * Expand existing markets and penetrate new markets for Hawaii's products and services. * Stimulate the development and expansion of economic activities which will benefit areas with substantial or expected employment problems. The Urban classification would be consistent with the Economic, Land Use and Industrial goals and policies of the Hawaii County General Plan by creating industrial uses. The goals, policies, standards and courses of action state the following: Economic Element * Provide residents with opportunities to improve their quality of life. * Economic development and improvement shall be in balance with the physical and social environments of the island of Hawaii. * The County of Hawaii shall strive for diversity and stability in its economic system. Honorable James Y. Arakaki, Chairman and Members of the County Council Page 3 * The County shall provide an economic environment which allows new, expanded, or improved economic opportunities that aze compatible with the County's natural and social environment. * The County of Hawaii shall strive for an economic climate which provides its residents an opportunity for choice of occupation. Land Use Element * Designate and allocate land uses in appropriate proportions and mix and in keeping with the social, cultural and physical environments of the County. * Zone urban- and rural-types of uses in azeas with ease of access to community services and employment centers and with adequate public utilities and facilities. * Allocate appropriate requested zoning in accordance with the existing or projected needs of neighborhood, community, region and County. * The County shall encourage the development and maintenance of communities meeting the needs of its residents in balance with the physical and social environment. * Zoning request shall be reviewed with respect to General Plan designation, district goals, regional plans, State Land Use District, compatibility with adjacent zoned uses, availability of public services and utilities, access and public need. Industrial Element * Designate and allocate industrial areas in appropriate proportions and in keeping with the social, cultural and physical environments of the County. * Promote and encourage the rehabilitation of industrial areas which are serviced by basic community facilities and utilities. * It shall be the policy of the County to achieve a broader diversification of local industries by providing opportunities for new industries and strengthening existing industries. * Through its zoning powers, the County shall locate industrial azeas convenient to transportation facilities, and provide a vaziety of industrial zoned districts and lot sizes, depending on the needs of the industries and the communities. * Industrial development shall be located in azeas adequately served by transportation, utilities and other amenities. Redeveloping or newly developing areas shall be developed in concert with programmed public and privately funded infrastructure to meet the expected needs. Honorable James Y. Arakaki, Chairman and Members of the County Council Page 4 * Topography of industrial land shall be reasonably level. * Industrial development shall be conveniently located to its labor resource. * Buffer zones shall be established between industrial and adjacent noncompatible uses of land. * The County shalt identify sites suitable for future industrial activities In addition, the Land Use Pattern Allocation Guide (LUPAG) Map component of the General Plan represents the document's goals, policies, standards and courses of action to guide the coordinated growth and development of the County. This map reflects a graphic depiction of the spatial relationships among various land uses and the expressed policy statements of the document itself. It also establishes the basic land use pattern for azeas within the County and is therefore an important consideration. This reclassification action also conforms to the LUPAG Map which designates the azea for Industrial. The Industrial designation was originally imposed for the Puna Sugar Mill operation. This designation allows for uses such as manufacturing and processing, wholesaling, large storage and transportation facilities and light industrial uses. The Puna Generating Plant, a power plant, would be included in these uses. The Urban reclassification of the subject property would serve to justify the existing industrial activities associated with the Puna Generating Station. The subject property is a portion of the old Puna Sugar Mill site which was designated Industrial since 1971. During the 1989 General Plan Comprehensive Review, this Industrial designation was expanded by redesignating lands in the vicinity from Intensive Agricultural and Orchards to Industrial. This area was considered for industrial expansion as a variety of Industrial/Agricultural uses were established in the vicinity through the Special Permit process. The County had determined that the industrial designation would promote and encourage additional utilization of the area. Also in 1989, it was observed that traffic patterns already indicated tremendous movement across the Puna-South Hilo District boundary. Keaau is in close proximity to the City of Hilo and has an excellent transportation link via the Volcano Highway-Kanoelehua Avenue. In addition, Keaau provides a natural focal point provided by the highway system that could result in the concentration of additional goods and services at Keaau. To facilitate this growth, during the 1989 review, the lands on the eastern side of the existing Keaau urban area were redesignated from Orchazds and Urban Expansion to Low Density Urban. Likewise, the lands to the west and southwest side of Keaau Town were redesignated from Orchards to Urban Expansion. As evident by the County's action during the 1989 General Plan Comprehensive Review, there definitely is a need for additional lands to accotnmodate present and future industrial activities for the Puna District. The azea under consideration is consistent with the urban form of Industrial as established for this section of the Puna District and as depicted on the LUPAG Map. The project site is concurrently being reclassified from an Agricultural (A-20a) to General Industrial (MG-10) zoned district in order to conform and recognize the Urban nature of the use. As such, the boundary amendment would allow for rezoning of the property to allow for the industrial activities and uses that aze already existing and permitted within an Urban district. Honorable James Y. Arakaki, Chairman and Members of the County Council Page 5 The subject property is located one mile from Keaau Town Center and in close proximity to the residential neighborhoods. Therefore, the lands could be chazacterized by "city-like" concentrations of people, structures, streets, urban level of services and other related land uses. Surrounding properties consist of formerly cultivated sugaz cane lands, small agricultural operations, vacant lands and residences. New uses as approved through special permits and rezonings will include fazm dwellings, mixed commercial-industrial uses, aschool/church and a greenhouse business. To the northeast of the subject property is the existing AMFAC Tropical Products tropical fruits packing facility and papaya puree processing facility. To the east of the subject property is the existing AMFAC Tropical Products tropical fruit packing and papaya puree processing facilities. Adjacent and southwest of the property is the McCully property, TMK: 1-6-03:5, which recently secured a State Land Use Boundazy Amendment from Agricultural to Urban and a Change of Zone from A-20a to FA-3a (Ordinance No. 97-67) and MCX-20 (Ordinance 98-61). The FA-3a zoned portion of TMK: 1-6-03:5 abuts the Puna Generating Station. Also, to the south along Milo Street is the site of Greenhouse Specialists (SPP-931) and the existing Pacific Floral Exchange business. Adjacent and to the east of Pacific Floral Exchange is the proposed school site for Hawaii Christian Camping Association (SPP-925). It should be pointed out, that when the special permit for the school/church was approved, the Hawaii Christian Camping Association was aware of the Puna Generating Station. They expressed no objections to being located in the same vicinity. A condition was included m SPP 925 that the school relocate should the health and safety of the school/church be a concern. Lands to the southwest of the subject property, along the first 1,800± section of Milo Street, are lots approximately 13,000 squaze feet in size which aze zoned RS-10. Existing uses along Milo Street aze mainly single-family residential in nature. A few RS-15 zoned properties aze also located in the azea. Along the intersection of Milo Street and the Old Volcano Road aze properties zoned CV-10. Approximately 800 feet to the south at the Keaau-Pahoa/Old Volcano Road intersection is the Keaau Town Center. Across Milo Street to the south is the site of the proposed Greenhouse Specialists' operation and to the southeast is the existing Pacific Floral Exchange business. Adjacent and to the east of Pacific Floral Exchange is the proposed school site for Hawaii Christian Camping Association. Lands further west and southwest aze primarily in residential uses. From a land use perspective, it is amore feasible alternative to expand urban development within this particulaz azea of Keaau. Furthermore, an Urban classification would complement the existing and future industrial land activities of the surrounding properties. Therefore, the urbanization of the subject property will not contribute toward scattered spot urban development. The urban classification also conforms to the standard that the development is within reasonable proximity to centers of trading and employment and to basic services such as schools, police and fire protection, transportation systems and water. The project site is located approximately one mile from the urban retail/ employment of Keaau Town Center. The Police, Fire and emergency medical services are also located in Keaau town, less than a mile from the subject property. Keaau is centrally located at the junction of two major highway systems in the Puna District, the Volcano Highway-Kanoelehua Avenue and Keaau-Pahoa Highway. The principal access to the proposed development would be provided from Keaau Road (TMK: 1-6-03: Portion of 73) and TMK: 1-6-03: Portion of 15, which are graveled roadway easements owned by Honorable James Y. Arakaki, Chairman and Members of the County Council Page 6 W.H. Shipman, Ltd. The Keaau By-Pass Road, presently under construction will be located within the vicinity of these roads. Applicable roadway easement improvements will be reviewed under the Change of Zone request. County water is available to the subject property as well as three existing wells. All other utilities and services are available to the subject property. Based on the foregoing, the request conforms with the Land Use Commission Rules which encourages urban developments in close proximity to existing developments and to existing services and facilities. The project area includes lands with no severe geological or topographical problems which cannot be properly rectified or which would render the land unusable. The subject property is relatively level with a slight grade. According to the Flood Insurance Rate Map (FIRM), the project area is within Zone X, area determined to be outside the 500-year flood plain. The project area is also located outside of any tsunami inundation azea. Any new construction or improvements to the project area must comply with Chapter 27 of the Counry Code relating to Flood Hazazd Control. The subject property was formally cultivated in sugaz cane and therefore, no endangered or threatened species of floral or fauna nor any archaeological sites are anticipated to be found on the subject property. The State of Hawaii ALISH Map classifies the property as Urban. The Land Use Study Bureau's Overall Master Productivity Rating for the soils in the area is "C" or Fair. Thus, the reclassification does meet with the standrsd which states that the lands included within the urban district shall be those with satisfactory topography and drainage and reasonably free from the danger of floods, tsunami and unstable soil conditions and other adverse environmental effects." Based on the above findings, the approval of the State Land Use Boundary Amendment from Agricultural to Urban District complements the State Land Use District Regulations and is supportive of the State of Hawaii Plan and the County General Plan. Therefore, the State Land Use Boundary Amendment is recommended to be given a favorable consideration. Should the State Land Use Boundary Amendment be approved, the existing Special Permit No. 686 for the power plant, will be voided. Change of Zone In order to consider an area for any type of zoning designation, the applicable goals, policies and standards of the General Plan must be adequately addressed. It is only through such a comprehensive policy analysis approach that evaluations and decisions can be made to better time and stage developments to achieve growth determined by the General Plan and reiated planning documents. The implications of these evaluations and decisions must be also considered as they may have an impact on similar areas in the County, but ultimately, on the future development of the whole island. The proposed rezoning would be consistent with the Economic, Land Use and Industrial goals, policies, standazds and courses of action of the General Plan. Honorable James Y. Arakaki, Chairman and Members of the County Council Page 7 Economic Element * Provide residents with opportunities to improve their quality of life. * Economic development and improvement shall be in balance with the physical and social environments of the island of Hawaii. * The County of Hawaii shall strive for diversity and stability in its economic system. * The County shall provide an economic environment which allows new, expanded, or improved economic opportunities that are compatible with the County's natural and social environment. * The County of Hawaii shall strive for an economic climate which provides its residents an opportunity for choice of occupation. Land Use Element * Designate and allocate land uses in appropriate proportions and mix and in keeping with the social, cultural and physical environments of the County. * Zone urban- and rural-types of uses in azeas with ease of access to community services and employment centers and with adequate public utilities and facilities. * Allocate appropriate requested zoning in accordance with the existing or projected needs of neighborhood, community, region and County. * The County shall encourage the development and maintenance of communities meeting the needs of its residents in balance with the physical and social environment. * Zoning request shall be reviewed with respect to General Plan designation, district goals, regional plans, State Land Use District, compatibility with adjacent zoned uses, availability of public services and utilities, access and public need. Industrial Element * Designate and allocate industrial azeas in appropriate proportions and in keeping with the social, cultural and physical environments of the County. * Promote and encourage the rehabilitation of industrial azeas which are serviced by basic community facilities and utilities. * It shall be the policy of the County to achieve a broader diversification of local industries by providing opportunities for new industries and strengthening existing industries. Honorable James Y. Arakaki, Chairman and Members of the County Council Page 8 * Through its zoning powers, the County shall locate industrial areas convenient to transportation facilities, and provide a vaziety of industrial zoned districts and lot sizes, depending on the needs of the industries and the communities. * Industrial development shall be located in areas adequately served by transportation, utilities and other amenities. Redeveloping or newly developing areas shall be developed in concert with programmed public and privately funded infrastructure to meet the expected needs. * Topography of industrial land shall be reasonably level. * Industrial development shall be conveniently located to its labor resource. * Buffer zones shall be established between industrial and adjacent non compatible uses of land. * The County shall identify sites suitable for future industrial activities The applicant's overall objective is to legitimize the existing use of the Puna Generating Plant. The power plant operations originally were run by Puna Sugar Company, Ltd. as a part of their sugar mill operations. However, when the mill closed, HELCO took over the power plant operations and secured a Special Permit (SPP 686) in order to continue the plant. The rezoning designation from A-20a to MG-l0a would make the power plant a permitted use under the industrial zoning. No immediate changes or expansion to operations aze planned through the yeaz 2017. The generating capacity at the site may be increased after the year 2017. The surrounding properties consist of a mixture of industrial type and agricultural processing uses which were granted Special Permits. Surrounding properties consist mainly of formerly cultivated sugar cane lands, vacant lands, small agricultural operations and residences. To the northeast of the subject property is the existing AMFAC Tropical Products tropical fruits packing facility and papaya puree processing facility. To the east of the subject property is the existing AMFAC Tropical Products tropical fruit packing and papaya puree processing facilities. Adjacent and southwest of the property is the McCully property, TMK: 1-6-03:5, which recently secured a State Land Use Boundary Amendment from Agricultural to Urban and a Change of Zone from A-20a to FA-3a (Ordinance No. 97-67) and MCX-20 (Ordinance 98-61). The FA-3a zoned portion of TMK: 1-6-03:5 abuts the Puna Generating Station. Also, to the south along Milo Street is the site of Greenhouse Specialists (SPP-931) and the existing Pacific Floral Exchange business. Adjacent and to the east of Pacific Floral Exchange is the proposed school site for Hawaii Christian Camping Association (SPP-925). It should be pointed out, that when the special permit for the school/church was approved, the Hawaii Christian Camping Association was aware of the Puna Generating Station. They expressed no objections to being located in the same vicinity. A condition was included in SPP 925 that the school relocate should the health and safety of the school/church be a concern. Lands to the southwest of the subject property, along the first 1,8001 section of Milo Street, are lots approximately 13,000 square feet in size which are zoned RS-10. Existing uses along Milo Street are mainly single-family residential in nature. A few RS-15 zoned Honorable James Y. Arakaki, Chairman and Members of the County Council Page 9 properties aze also located in the area. Along the intersection of Milo Street and the old Volcano Road are properties zoned CV-10. Approximately 800 feet to the south at the Keaau-Pahoa/Old Volcano Road intersection is the Keaau Town Center. Across Milo Street to the south is the site of the proposed Greenhouse Specialists' operation and to the southeast is the existing Pacific Floral Exchange business. Adjacent and to the east of Pacific Floral Exchange is the proposed school site for Hawaii Christian Camping Association. Lands immediately adjacent to and west of the subject property are vacant formerly sugar cane lands. However, lands further west and southwest are primarily in residential uses. Existing industrial zoned lands in the Puna District aze located off Highway 11 at the Shipman Industrial Park, approximately .7 miles from the subject property. The County Council approved the General Industrial (MG-20) zone district effective August 19, 1986, for approximately 488 t acres of land for the development of Shipman Industrial Park. A portion of the Shipman Industrial Pazk has been subdivided in increments between 1987 - 1991. There are presently a total of 88 lots with average lot size ranging from one half acre to 3 acres. The existing uses in the area include: heavy equipment construction baseyards, building supplies baseyazds, paving construction baseyazds, distributor warehousing, supermarket warehousing, industrial/manufacturing baseyazds and other uses. Allied Aggregates leases one of the larger lots for its existing quarrying operation. For the East Hawaii area, industrial zoned lands and activities are primazily located in the City of Hilo at the Hilo Harbor, airport and Kanoelehua Industrial areas. Industrial expansion since 1970 has largely occurred through the expansion and in-filling of these areas. The subject property has been in industrial use. The Land Use Pattern Allocation Guide (LUPAG) Map component of the General Plan is a representation of the document's goals, policies, standards and courses of action to guide the coordinated growth and development of the County. It reflects a graphic depiction of the spatial relationships among various land uses and the expressed policy statements of the document itself. The LUPAG Map establishes the basic land use pattern for areas within the County. Therefore, changes and requests for amendments to the LUPAG Map must be evaluated against applicable goals, policies and standazds of the General Plan. The reclassification action also conforms to the LUPAG Map which designates the area for Industrial Area. The Industrial Area designation include uses such as manufacturing and processing, wholesaling, large storage and transportation facilities and light industrial uses. The zoning reclassification would be in keeping with industrial activities associated with the Industrial designation and the existing industrial/agricultural uses in the area. Since 1971, the area of the old Puna Sugar Mill has been designated as Industrial Area. During the 1989 General Plan Comprehensive Review, the Industrial Area designation was expanded by tedesignating lands in the vicinity from Intensive Agricultural and Orchards to Industrial. This area was considered for industrial expansion as a variety of Industrial uses have been established in the vicinity through the Special Permit process. The County had determined that the industrial designation would promote and encourage additional utilization of the area. Also in 1989, it was observed that traffic patterns already indicated tremendous movement across the Puna-South Hilo District boundary. Keaau is in close proximity to the City of Hilo and Honorable James Y. Arakaki, Chairman and Members of the County Council Page 10 has an excellent transportation link via the Volcano Highway-Kanoelehua Avenue. In addition, Keaau provides a natural focal point provided by the highway system that could result in the concentration of additional goods and services at Keaau. To facilitate this growth, during the 1989 review, the lands on the eastern side of the existing Keaau urban area were redesignated from Orchards and Urban Expansion to Low Density Urban. Likewise, the lands to the west and southwest side of Keaau Town were redesignated from Orchards to Urban Expansion. As evident by the County's action during the 1989 General Plan Comprehensive Review, this redesignation would be consistent with the present and future industrial activities for the Puna District. An amendment to the State Land Use Boundary Map from an Agricultural to Urban District is being concurrently processed for the proposed industrial development. Upon the adoption of this amendment, the proposed change of zone request will be consistent with the proposed Urban District designation. The project site is situated within close proximity to schools, commercial azeas, employment centers and public safety services. The site is located within an azea where there is existing agricultural activity and residences; and proposed residences, businesses and a school. The project site is located approximately one mile from the urban retail/employment of Keaau Town Center. Police, Fire and emergency medical services are also located in Keaau town, one mile from the subject property. Keaau is centrally located at the junction of two major highway systems in the Puna District, the Volcano Highway-Kanoelehua Avenue and Keaau-Pahoa Highway. Due to the fact that the residences, agricultural activities, businesses and schools aze located within the vicinity of the subject site, an Emergency Plan is required to be submitted. All utilities and services aze or will be made available to the project site which aze essential to accommodate urban development. The principal access to the proposed development is from Keaau Road (TMK: 1-6-03: Portion of 73) and over TMK:1-6-03:Portion of 15. Both aze graveled roadway easements owned by W.H. Shipman, Ltd., of which HELCO is authorized to use. The Keaau By-Pass Road is also proposed to be located within this vicinity. According to a handout, dated November 18, 1998 by the Department of Transportation, Highways Division, Hawaii District, the Keaau By-Pass Road will begin at the Old Keaau Road and end near the Humane Society. Completion is estimated for mid-July 1999. The Old Volcano Road/Keaau By-Pass Road (presently Keaau Road) intersection, is proposed to be reconstructed. The Department of Transportation had no comments to offer on this request. A condition is included that the access roadway easements be paved to a width of 20 feet from its intersection with the Old Volcano Road to the entrance gate of the subject property. As the Keaau By-Pass Road is presently under construction, these improvements may be made in conjunction with any roadway improvements for the Keaau By-Pass Road. The project area has no severe geological or topographical problems which cannot be properly rectified or which would render the land unusable. The subject property is relatively level with a slight grade. According to the Flood Insurance Rate Map (FIRM), the project azea is within Zone X, area determined to be outside the 500-year flood plain. The project area is also located outside of any tsunami Honorable James Y. Arakaki, Chairman and Members of the County Council Page 11 inundation azea. Any new construction or improvements to the project area must comply with Chapter 27 of the County Code relating to Flood Hazazd Control. The subject property is the site of the Puna Generating Station and will continue operation as such. As the property has been developed, no endangered or threatened species of floral or fauna nor any azchaeological sites are anticipated to be found on the subject property. The State of Hawaii ALISH Map classifies the property as Urban. The Land Use Study Bureau's Overall Master Productivity Rating for the soils in the azea is "C" or Fair. There is no agricultural activity on the subject property. Therefore, the change of zone for this azea will not be detrimental to the reduction of this azea from the agricultural land inventory in the County of Hawaii. Based on the above findings, this request for a Change of Zone from an Agricultural (A-20a) to a General Industrial (MG-10) zoned district would result in an appropriate land use pattern and further the welfare and convenience of the general public. Therefore, it is recommended that this request be approved. A condition is included that the Special Permit No. 686 be voided upon the effective date of this change of zone. For your favorable consideration, an amendment to the SLU Boundazies Map H-66, for the County of Hawaii, and an amendment to Section 25-103/25-8-22 (Puna District Zone Map) of the County Zoning Code aze transmitted. We are enclosing copies of the applications, a copy of the staff background, and additional comments for your information.

SUBJECT REQUEST 1. Details of Proposal a. Subject Request and Property Description The applicant, Hawaii Electric Light Company, Inc. (HELLO), is the owner of the site containing the Puna Generating Station. HELLO is requesting: • State Land Use boundary amendment from the Agriculture to Urban District (pursuant to Hawaii Revised Statute (HRS) Section 205-3.1, as amended, and Chapter 28 of the Hawaii County Code), and • County rezoning from Agricultural (A-20a) to MG-10a. HELCO's Puna Generating Station is identified as Tax Map Key (TMK) 1-6-03:93. The HELLO site is comprised of a portion of the former Puna Sugar mill property and a portion of a former railroad right-of-way. The HELLO site is located in the Puna District, County of Hawaii. Figure One depicts the location of the site. Figure Two is a site plan of the Puna Generating Station, depicting all existing uses and structures. Figure Two does not reflect any new structures, as there aze none that are currently planned. Appendix A is a metes and bounds description of the subject property. Power generation was originally undertaken in conjunction with the operation of the sugar mill that previously occupied the site. Electricity was generated for both the sugar operations and employee-residents. Until the sugar mill ceased operations in the eazly-1980s, the power generation activity was an ancillary use of a permitted agricultural activity. After the sugar operations ceased, HELLO acquired a portion of the mill site to continue generating power. In late 1988, the Hawaii County Planning Commission approved HELCO's request for a Special Permit for the site. Special Permit No. 686 allowed HELLO to establish the electric power plant and related improvements as the principal use of the site. The Special Permit was required, since the power generation use was no longer an ancillary use to a permitted agricultural activity. The Special Permit does not impose any conditions limiting the generation capacity or the mix of related improvements on the site. In 1992, HELLO initiated service of a 20.8-MW combustion turbine unit-three (CT- 3) generation unit at the Puna Generating Station.

Statement of Objectives and Reason for the Request HELLO wants to rezone the site from an agricultural zoning designation to the County's general industrial designation. The general industrial zoning designation is consistent with the current use of the site and the County's General Plan "Industrial" designation for the site and surrounding area. By a letter dated February 3, 1997, the County Planning Director confirmed that the HELLO Puna Generating Station site is within the area designated as "Industrial" by the General Plan Land Use Pattern Guide (LUPAG) Map. The letter also confirmed that Special Permit No. 686 does not impose any conditions limiting the expansion of the site's generation capacity and related improvements. (Letter dated Februazy 3, 1997, from Ms. V. K. Goldstein, Planning Director, Hawaii County.) HELCO's request for both an amendment of the State Land Use Boundary to the Urban District, and the request for an amendment of the County's zoning designation to general industrial conforms with the County General Plan LUPAG map designation for the site and applicable sections of the General Plan. c. Number of Acres TMK 1-6-03:93 has an azea of 10.5 acres, and is comprised of the 9.3-acre former mill site and a 1.2-acre azea that was part of a railroad right-of-way. d. Proposed Use (units/lots/floor azea) HELLO plans to continue using the site to generate electricity and for related ancillary improvements. These aze currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988. Generation Capacity The Puna Power Plant site currently includes a 15.5 MW steam unit acquired from AMFAC and a 20.8 MW combustion turbine generator (CT-3). HELCO's most current resource plan for power-generation needs are attached as Table One. The table is based on information set forth in a document titled "Hawaii Electric light Company, Ltd. 1998 Electric Utility System Cost Data Filling," prepared by Hawaiian Electric Company, Inc., and dated June 30, 1998 The aforementioned resource plan indicates anticipated additions, retirements, and status changes for HELCO's generation sources, including non-HELLO generation sources, through the yeaz 2017. HELCO's resource plan indicates that through the year 2017, HELLO does not plan to expand the generation capacity at the Puna (4) Table One HELCO Resource Plan: 1998 to 2017 Power Facility Additions and Retirements for the Island of Hawaii As of June 30,1998 Reduced Peak Net with Reserve Reserve Peak DSM= System Margin Margin Resource Capacity Year (MW) (MW) Ca abili (MW) Percent Descri lion Chan a Date MW~ 1998 173.3 165.0 223.0 58.0 35.2 CT-4 Add 12/98 19.90 217.5 52.5 31.8 Keahole D-18-19 Retire 12/98 (5.50) 237.4 72.4 43.9 CT-5 Add 12/98 19.90 234.7 69.7 42.2 Keahole D-206 Retire 12/98 (2.75) 1999 175.2 166.0 256.7 90.7 54.6 Encogen Phase 1 Add 4/99 22.00 253.6 87.6 52.8 Shipman 16 Retire 4/99 (3.07) 250.6 84.6 51.0 Waimea Retire 4/99 (3.00) D-8,9,10° 242.3 76.3 46.0 Waimea Retire 4/99 (8.25) D-12,13,146 280.3 114.3 68.9 Encogen Add 8/99 38.00 Phase 2 268.8 102.8 61.9 Kancelehua Retire 8/99 (11.50) CT-16 266.8 100.8 60.7 Kanoelehua Retire 8/99 (2.00) D-116 258.6 92.6 55.8 Kancelehua Retire 8/99 (8.25) D-15,16,176 250.3 84.3 50.8 Keahole Retire 8/99 (8.25) D-206 235.4 69.4 41.8 Puna Standby 8/99 (14.98) Steam6 213.4 47.4 28.5 HCPC Retire 12/99 (22.00) Contract termination 2000 177.2 167.0 213.4 46.4 27.8 2001 180.1 168.9 213.4 44.5 26.3 (Table One, continued on next page) (5) Table One (continued) HELCO Resource Plan: 1998 to 2017 Power Facility Additions and Retirements for the Island of Hawaii As of June 30,1998 Reduced Peak Net with Reserve Reserve Peak DSMx System Margin Margin Resource Capacity Year (MW) (MW) Ca abili (MW) Percent Descri lion Chan a Date MWa 2002 184.0 171.9 213.4 41.5 24.1 2003 188.0 174.9 228.3 53.4 30.5 Puna Steam Return 14.98 2004 192.2 178.0 228.3 50.3 28.3 2005 196.6 181.3 221.2 39.9 22.0 Shipman 3 Retire (7.09) 2006 201.4 186.0 237.9 51.9 27.9 ST-7 (CT-4 Add 16.70 and 5 to DTCC) 2007 206.3 190.3 237.9 47.6 25.0 2008 211.4 194.6 230.6 36.0 18.5 Shipman 4 Retire (7.31) 2009 216.5 198.7 251.6 52.9 26.6 DTCT-PHl Add 20.92 (A) 2010 221.7 202.9 251.6 48.7 24.0 2011 227.4 207.7 251.6 43.8 21.1 2012 233.2 212.9 272.5 59.6 28.0 DTCT-PH2 Add 20.92 (A) 2013 239.2 218.4 272.5 54.1 24.8 2014 245.4 224.0 272.5 48.5 21.6 2015 251.7 229.6 259.0 29.4 12.6 Hi115 Retire (13.46) 2016 258.4 235.7 277.9 42.2 17.9 DTCT-PH3 Add 18.90 (A) 2017 265.3 242.0 298.8 58.8 23.5 DTCT-PH1 Add 20.92 (B) Abbreviations: CT =Combustion turbine; DTCT-PH# =dual-train first or second CT; DTCC-PH# =dual train combined cycle ~ Net peaks are from HELCO "Recommended Annual GWh Sales and Net Peak Forecast;' dated September 11,1997. = Reduced peak is net peak less impart from DSM, HMEC, and off-peak rider confraMS.

The Puna Steam unit is scheduled to return to service in 2003 to defer the need for ST-7. Source: "Hawaii Electric Light Company, Ltd. 1998 Electric Utility System Cost Data Filling," prepared by Hawaiian Electric Company, Inc., June 30, 1998. (6) Generating Station site. The only changes currently anticipated at the Puna Station is placing the 15.5 MW steam generation unit on a cold standby status in 1999, and returning the steam unit to active status in the yeaz 2003. While HELCO's current resource plan does not reflect increasing the generation capacity at the Puna Generating Station through the yeaz 2017, the generation capacity at the site may be increased sometime in the future after the year 2017. Further, changes in the assumptions used to prepare the resource plan could lead also to changes in the generation capacity needed by HELCO at the Puna site prior to the year 2017. Related Improvements Related improvements include non-generating and ancillary uses at HELCO's Puna Generating Station. These include fuel storage, water pumps and storage, a switchyazd, and transmission lines and related facilities. HELCO currently has no plans to add any related improvements at the Puna Generating Station. However, these may be increased at some yet unspecified time in the future. e. Time Frame and Cost Since HELCO currently has no plans to increase the generation capacity or to expand the related improvements at the Puna Generating Station, the time frame and cost are not relevant. f. Employees and Others Using Site HELCO's current full- and part-time staffing for the Puna Generating Station consists of three shifts with two employees per shift. Other HELCO staff visits the site, as required by specific tasks. HELCO also occasionally has contractors working a[ the site for specific tasks. County Water Depaztment staff occasionally service the department's facilities located within the HELCO site. 'i here are not any Water Department personnel assigned to the site on a full- or pazt-time basis. The site has a security fence and a locked security entry gate. The fence and gate are to preclude unauthorized personnel and vehicles from entering the site. The fence generally follows the site's property line, although along Keaau Road the fence is set back from the property line. (7) g. Parking Arrangements The site has on-site paved and graveled areas within the fenced portion of the site to meet the pazking requirements of the County zoning code. No off-site pazking is required or contemplated. h. Traffic Impacts Existine Conditions The primary access to the Puna Generating Station site is from Mamalahoa Highway via Keaau Road. Mamalahoa Highway (State Route 11, elsewhere referred to as Routes 19 and 190, and also known as Hawaii Belt Road) is a major arterial serving most of the Island of Hawaii. Within the vicinity of the HELCO site, Mamalahoa Highway is afour-lane highway that runs generally in the north-south direction. Keaau Road is a private road providing access from Old Volcano Road to the existing HELCO Generating Station. The two-lane Old Volcano Road runs pazallel and east of Mamalahoa Highway. Keaau Road crosses Old Volcano Road. The current staffing of the generating station consists of three shifts with two employees per shift. Diesel fuel deliver currently is comprised of 21 to 49 trips per week. Weekday morning (AM) and afternoon (PM) period traffic counts were conducted by Austin, Tsutsumi & Associates, Inc. (ATA) at two intersections in the morning and evening peak period on Mazch 19 and 20, 1997. Appendix B is the ATA report of the traffic analysis titled "HELCO's Puna Generation Facility Traffic Assessment." The two intersections analyzed in the report are Keaau Road and Mamalahoa Highway, and Keaau Road and Old Volcano Road. The following summarizes the report's findings: • During the morning AM peak period, the peak direction of traffic flow on Mamalahoa Highway is in the northbound direction with approximately 2,640 vehicles during the peak hour and approximately 640 peak hour vehicles in the southbound direction. During the afternoon PM peak period, the peak direction of flow is in the opposite direction with approximately 1,800 peak hour vehicles in the southbound direction and approximately 770 peak hour vehicles in the northbound direction. • It was observed that during the PM peak period, a relatively high number of southbound vehicles (267 vehicles per hour (vph)) on Mamalahoa Highway turn left onto Keaau Road and then turn right onto Old Volcano Road. It is assumed that most of these motorists are bound for the residential areas of Keaau Town. • Based on the existing traffic count data, the number of vehicles that utilizes Keaau Road serving the HELCO facility area is relatively low. During the AM peak (8) hour, only 46 vph with 12 vph in the westbound and 34 in eastbound direction were observed. During the PM peak hour, only 33 vph utilize Keaau Road with 27 in the westbound direction and 6 in the eastbound directions. • Level of Service (LOS) is a qualitative measure used to describe the conditions of traffic flow, ranging from free-flow conditions at LOS "A" to congested conditions at LOS "F." The methods utilized in the ATA traffic analysis for calculating delays and corresponding levels of service at stop-controlled intersections are based on the 1994 Hi ehway Capacity Manual -Special Report 209. • The ATA traffic analysis indicates that during the AM peak hour, the southbound left-turn from Mamalahoa Highway to Keaau Road is operating at LOS F. Long delays to this particular movement are mainly due to the number of northbound opposing vehicles on Mamalahoa Highway. The westbound left-turn from Keaau Road to Mamalahoa Highway is also operating at LOS F during the AM peak hour, but this only affects a small number of vehicles (only one vehicle during the peak hour was observed). The remaining movements at both intersections are operating at acceptable levels of services (LOS A, B, C or D). • Based on existing traffic volumes plus expected ambient growth in traffic caused by regional growth throughout the Island of Hawaii, traffic growth is anticipated to be 1% per year. In the year 2001, the peak hour operations at both intersections are expected to be similar to existing 1997 operating conditions. • ATA recommends that no improvements are necessary at the intersections of Mamalahoa Highway and Keaau Road. Although the westbound left-turn is currently operating at an undesirable level of service, only a small number of vehicles are affected. And although the southbound left-turn from Mamalahoa to Keaau Road is operating at an undesirable level of service, this only occurs during the morning peak period when the opposing northbound approach is heavy. Based on the traffic counts conducted by ATA, most of these vehicles are bound for Keaau Town, which can also be accessed by Ahoa Street and Kalapana Road further south. Keaau Bypass Road The State Department of Transportation, Highways Division, is currently constructing the first phase of a two-phase project comprised of a four-lane bypass road routing Keaau-Pahoa (State Highway 130) traffic around the Keaau Town. An environmental assessment (EA) was prepared for the project's proposals, and a "Notice of Determination Negative Declaration" was completed and accepted in December 1995 for the Keaau-Pahoa bypass road, State Department of Transportation, Highways Division Project No. 130-B-O1-92. (9) The alternative selected for the 2.2-mile project will begin on the Keaau-Pahoa Road, in the vicinity of the former plantation manager's house (now referred to as Banyan Inn) proceed between 8-1/2 Mile Camp and the Milo Street neighborhood, and return to Route 11 (Mamalahoa Highway) at Keaau Road. A traffic analysis for the Keaau-Pahoa Road EA was prepared by Barton-Aschman Associates, Inc., and is dated December 1993. The traffic report indicates that if the bypass road were not built, significant improvements would have been required on Route 11 (Mamalahoa Highway). The Keaau-Pahoa Road EA traffic analysis also indicates that construction of the bypass road will favorably impact the road intersections serving the HELCO Puna Generating Station and improve the LOS at the intersection of Keaau Road and Route 11 (Mamalahoa Highway). Telephone conversations with a representative (personal conversations with Robert Taira, Design Engineer, May 6 and 8, 1998) of the State Department of Transportation, Highways Division, indicates that the bypass road intersection at Route 11 (Mamalahoa Highway) will be fully signalized with right- and left-turn lanes and acceleration and deceleration lanes. For traffic turning onto Keaau Road from the bypass road, there will be deceleration lanes and turning pockets with a stop sign for left turns on to Keaau Road. For traffic turning from Keaau Road onto the bypass road, a stop sign will be located on Keaau Road and acceleration lanes will be constructed on the new highway. i. Other Related Information There is no other related information. j. Proposed On-site and Off-site Infrastructure There is no on- or off-site infrastructure that would be impacted. B. CONFORMANCE WITH STATE/COUNTY PLANS AND LAND USE DESIGNATIONS 2. Hawaii State Plan HELCO's proposed reclassification of the Puna Generating station site conforms to the applicable goals, objectives, and policies of the Hawaii State Plan. The Hawaii State Plan, Chapter 226, "Hawaii Revised Statutes," is a guide for future long-range development. II identifies [he goals, objectives, policies, and priorities for the State; allocates limited resources; improves coordination among federal, state, and county agencies; and establishes a system for integrating all major state and county activities. Section 226-14 of the State Plan, Objectives and Policies for Facility Systems applies, in general, to the proposed project and states the following: (10) a. Planning for the State's facility systems in general shall be directed towards achievement of the objective of water, transportation, waste disposal, and energy and telecommunication systems that support statewide social, economic, and physical objectives. b. To achieve the general facility system objective, it shall be the policy of this State to: 1. Accommodate the needs of Hawaii's people through coordination of facility systems and capital improvement priorities in consonance with state and county plans 2. Encourage flexibility in the design and development of facility systems to promote prudent use of resources and accommodate changing public demands and priorities 3. Ensure that required facility systems can be supported within resource capacities and at reasonable cost to the user 4. Pursue alternative methods of financing programs and projects and cost-saving techniques in the planning, construction, and maintenance of facility systems. The HELCO Puna Generating Station will contribute to meeting the demand for electricity on the Island of Hawaii and to maintaining and improving system reliability. Section 226-18 of [he Hawaii State Plan, "Objectives and Policies for Facility Systems Energy/Telecommunications," applies specifically to the project and states the following: a. Planning for the State's facility systems with regard to energy shall be directed towards the achievement of the following objectives: 1. Dependable, efficient, and economical statewide energy systems capable of supporting the needs of the people 2. Increased energy self-sufficiency where the ratio of indigenous to imported energy use is increased; and 3. Greater energy security in the face of threats to Hawaii's enc rgy supplies and systems. b. To achieve the energy objectives, it shall be the policy of this State to ensure the provision of adequate, reasonably priced, and dependable power and telecommunication services to accommodate demand. c. To further achieve the energy objectives, it shall be the policy of this State to: 1. Support research and development as well as promote the use of renewable energy sources; 2. Ensure that the combination of energy supplies and energy-saving systems are sufficient to support the demands of growth; (11) 3. Base decisions of least-cost supply-side and demand-side energy resource options on a comparison of their total costs and benefits when a least-cost is determined by a reasonably comprehensive, quantitative, and qualitative accounting of their long-term, direct and indirect economic, environmental, social, cultural, and public health costs and benefits; 4. Promote all cost-effective conservation of power and fuel supplies through measures including: A. Development ofcost-effective demand-side management programs; B. Education; and C. Adoption of energy-efficient practices and technologies; S. Ensure to the extent that new supply-side resources are needed, the development or expansion of energy systems utilizes the least-cost energy supply option and maximizes efficient technologies; 6. Support research, development, and demonstration of energy efficiency, load management, and other demand-side management programs, practices, and technologies; and 7. Promote alternative fuels and energy efficiency by encouraging diversification of transportation modes and infrastructure. The Puna Generating Station, in the context of HELCO's integrated approach to energy production and conservation, conforms to these objectives and policies. At this time, alternative fuels and technologies do not represent the least-cost energy supply option or the maximum efficient technology. HELCO is also actively participating in education and reseazch programs to further develop alternative fuels and technologies in Hawaii. 3. State Energy Functional Plan HELCO's proposed reclassification of the Puna Generating station site conforms to the applicable priority guidelines of the Hawaii State Plan and the adopted functional plans. The Hawaii State Plan requires the development of State Functional Plans (SFPs). `,Vhile the Hawaii State Plan establishes long-term objectives for Hawaii, the SFPs delineate the specific strategies and prioritize actions that need to be addressed in the short term. The objectives of the State Energy Functional Plan (1991) are to achieve dependable, efficient, and economical statewide energy systems capable of supporting the needs of the people and to increase energy self-sufficiency. The major issues identified in the Plan that apply to the Puna Generating Station aze discussed below. The Puna Generating Station meets the objectives related to energy conservation, energy efficiency, and alternative and renewable energy; however, it does not address the objective of furthering energy self-sufficiency. (12) Energy conservation and efficiency can reduce the dependence on imported fossil fuels and overall energy demand. To achieve this, an Integrated Resource Plan (IRP) was developed and approved by the Public Utility Commission (PUC). Integrated Resource Planning is the process of developing, implementing, monitoring, and evaluating a utility resource plan that identifies an optimum mix of energy resources for meeting forecasted levels of consumer energy needs. Demand-Side Management (DSM) programs, which are a component of the IRP, were designed to influence customer consumption of electricity in a manner that will produce changes in the utility's demand. Potential programs include conservation, energy efficiency, load management, and fuel substitution. The energy conservation and efficiency policy and action items pertaining to the Puna Generating Station are as follows: Policy A(I): Promote and Stimulate Greater Energy Efficiency and Conservation in Non-Transportation Sectors Action A(1)(a): Provide Technical Support and Assistance to the State Government, County Governments, the PUC, and The Energy Utilities in Developing the Integrated Resource Planning (IRP) Process and Carrying Out Demand-Side Management (DSM) Assessments. Action A(1)(b): Advance the Use of Demand-Side Management (DSM) by Creating Pilot Programs and Promoting Education of Local Energy Producers and Users. Through the II2P process, HELCO has developed along-range energy plan for Hawaii County. The IRP developed energy plan considers both the traditional supply-side resources and the customer (demand-side) resources that are available. IRP has brought about changes in the way utilities conduct their business, by including demand-side options as a resource and by having the public participate in the planning process through advisory groups. HELCO formed an advisory group representing business, government, environmental, cultural, and community groups. Those groups with a special interest in energy issues, as well as individuals who could lend special expertise to the process, were included. The advisory group met several times during the plan development process. The meetings covered such areas as organizational issues, forecasting, demand-side resources, supply-side resources, and the IItP objectives and principles. Public meetings were also held to present the forecasted sales and peak demand, identify DSM and supply-side resource options, and to obtain feedback into the IRP process. These public meetings were also intended to introduce the IRP process to the general public so that they may have a better understanding of the participatory process. The IRP programs provide peak-demand saving. However, because energy efficiency and peak capacity reductions have not been comprehensively pursued by any organization in Hawaii to date, there is considerable uncertainty about how to structure the DSM programs. Monitoring of the implementation process will be important, and programs will need to be adjusted as the implementation process moves forward. HELCO expects (13) to update its DSM program plans annually to optimize program implementation and energy savings. The Slate is encouraging development of altemative and renewable energy sources as Hawaii's primary energy source. These resources include geothermal, ocean thermal (OTEC), solaz photovoltaic, biomass, wind, and hydropower. Although the State has made progress in altemative energy technologies, only geothermal currently provides a potential for firm, reliable electricity. It is the only commercially mature indigenous resource available in lazge quantities that can be converted to baseload (24-hour-per-day) electricity. Other alternative energy resources, such as solaz and wind technologies, do not provide firm, baseload power and aze not economically feasible at this time. HELCO has contributed to and constructed facilities for alternative and renewable energy resources, such as wind and hydroelectric power. HELCO also provides rebates to commercial users who install solaz power units. HELCO also has power purchase contracts with independent power producers. These power purchase contracts are based on alternative and renewable technologies. Examples include sugar cane bagasse and coal-fueled steam turbine generators. While extensive dependence on such contracts can increase supply risks, HELCO has evaluated and continues to evaluate IPP alternatives and renewable energy power supply offers. 4. Applicable Goals/Policies and Objectives of the Hawaii County General Plan A County Ordinance with an effective date of November 14, 1989, amended the Hawaii County General Plan. The General Plan has goals, policies and standards for 13 topics: economic, environmental quality, flood control and drainage, historic sites, natural beauty, natural resources and shoreline, housing, public facilities, public utilities, recreation, transportation, and land use. HELCO's request for both an amendment of the State Land Use Boundary to the Urban District, and the request for an amendment of the County's zoning designation to general industrial conforms with the County General Plan LUPAG map designation for the site and applicable sections of the General Plan. The following are the goals, policies, and standards that apply to [his project: Energy Policies • The County shall strive to assure a sufficient supply of energy to support present and future demands. Standards • New power plants shall incorporate devices which minimize pollution Public Utilities Goals • Ensure that adequate, efficient and dependable public utility services will be available to users • Maximize efficiency and economy in the provision of public utility services (14) • To have public utility facilities which are designed to fit into their surroundings or concealed from public view Policies • Public utility facilities shall be designed so as to complement adjacent land uses and shall be operated so as to minimize pollution or disturbance. • Provide utilities and service facilities that minimize total cost to the public and effectively service the needs of the community. • Utility facilities shall be designed to minimize conflict with the natural environment and natural resources. • Improvement of existing utility services shall be encouraged to meet the needs of users. • The County shall develop short- and long-range capital improvement programs and plans for public utilities within its jurisdiction and which are consistent with the County General Plan. Electricity Policies • The County should encourage electrical utility companies to develop a comprehensive plan for the generation, transmission, and distribution of electrical power to the various parts of the Islands. Standards • There shall be a minimization of obstruction of scenic views and vistas by electrical facilities. Land Use Goals • Designate and allocate land uses in appropriate proportions and miz and in keeping with the social, cultural, and physical environments of the County. Policies • Zone urban- and rural-types of uses in areas with ease of access to community service and employment centers and with adequate public utilities and facilities. • Promote encourage the rehabilitation and use of urban and rural areas which are services by basic community facilities and utilities. Industrial Land Use Goals • Designate and allocate industrial areas in appropriate proportions and in keeping with the social, cultural, and physical environment of the County. • Promote and encourage the rehabilitation of industrial areas that are serviced by basic community facilities and utilities. Policies • Through its zoning powers, the County shall locate industrial areas convenient to transportation facilities, and provide a variety of (15) industrial zoned districts and lot sizes, depending on the needs of the industries and the communities. 5. Slate Land Use Designation The site of the Puna Generating Station is currently designated by the State Land Use Commission (LUC) as part of the state's "Agricultural" district. HELCO is requesting through the County, an amendment of the site's Land Use District designation to the Urban District. The processing of [he boundary amendment through the County is pursuant to Hawaii Revised Statute (HRS) Section 205-3.1, as amended, and Chapter 28 of the Hawaii County Code. They allow the County to amend State Land Use district boundaries for lands 15 acres or Tess located in the State Land Use Urban, Rural, and Agricultural Districts. HELCO's request for an amendment of the State Land Use Boundary to the Urban District is reasonable and does not violate the standards for the Urban District of the State Land Use Boundaries as set forth in HRS 205-2. The standards used by the LUC for detemilning Urban District boundaries, as listed in HAR 15-15-18, and the relationship of the proposed project to them are discussed below. 1 It shall include lands characterized by "city-like" concentrations of people, structures, streets, urban level of services and other related land uses. 2. It shall take into consideration the following specific factors: A. Proximity to centers of trading and employment except where the development would generate new centers of trading and employment B. Substantiation of economic feasibility by the petitioner C. Proximity to basic services such as sewers, transportation systems, water, sanitation, schools, parks, and police and fire protection D. Sufficient reserve areas for urban growth in appropriate locations based on a ten-year projection 3. It shall include lands with satisfactory topography and drainage and reasonably free from the danger of floods, tsunami, unstable soil conditions, and other adverse environmental effects. 4. In determining urban growth for the next ten years, or in amending the boundary, land contiguous with existing urban areas shall be given more consideration than non-contiguous land, and particularly when indicated for future urban use on state or county general plans. 5. It shall include lands in appropriate locations far new urban concentrations and shall give consideration to areas of urban growth as shown on the state and county general plans. 6. It may include lands which do not conform to the standards in paragraphs I to S: (16) A. When surrounded by or adjacent to existing urban development B. Only when those lands represent a minor portion of this district 7. It shall not include lands, the urbanization of which will contribute toward scattered spot urban development, necessitating unreasonable investment in public infrastructure or support services. 8. It may include lands with a general slope of twenty percent or more which do not provide open space amenities or scenic values if the commission finds that those lands are desirable and suitable for urban purposes and that official design and construction controls are adequate to protect the public health, welfare and safety, and the public's interest in the aesthetic quality of the landscape. The Puna Generating Site is currently a heavy industrial use that reflects the continuation of a use established by the sugar operations that were discontinued in the 1980s. Slopes on the project site are minimal. The site does not lie in any flood or tsunami zones. The United States Department of Agriculture (USDA) Soil Conservation Service Soil Survey Report classifies the soils in the vicinity of the site as being in the Olaa series, and specifically the Olaa Silty Clay Loam (OaC). This series is characterized by moderately deep, moderately fine soil. Permeability is rapid, runoff is slow, and the erosion hazard slight. A culvert adjacent to the road serving the site drains into a drainage ditch parallel to the road. Standard on-site drainage improvements would accommodate any future intensification of the use of the site. HELCO will comply with all applicable regulations governing drainage. The location of the project site does not represent a significant adverse impact to scenic views or vistas, nor does it cause a significant adverse impact on the aesthetic quality of the landscape. The use of the site for generation and distribution of electricity does not significantly diminish the available supply of land used for agricultural activities, nor will it have any adverse impact on the remaining adjacent agricultural uses. The proposed project will not require extension of existing County or State infrastructure to the site and the project will not have any impact that will require the expenditure of public funds for infrastructure. HELCO and the Hawaii County Department of Water Supply (DWS) have sepazate groundwater wells on the Puna Generating Station site. The HELCO Puna Generating site has a minimal impact on any requirement for police and fire protection. (17) The site has no significant adverse impact on regional traffic and there is no mitigation measure recommended. The continued use of the site to generate and distribute electricity will not directly cause additional population growth on the Island of Hawaii. HECO is a subsidiary of Hawaiian Electric Company, Inc. (HECO), a company with publicly traded stock. The Public Utilities Commission (PUC) regulates HELCO. As a subsidiary of a publicly traded company, HELCO has access to the economic resources required to develop [he project. HELCO can request the authority from the PUC to make expenditures for construction of the proposed facility and to recapture costs through the electricity rates paid by HELCO's customers. HECO is also able to issue bonds and stock to finance the project. No such request is contemplated in conjunction with this application. The reclassification of the site to [he Urban district will not impact the provision of sufficient service areas for other urban growth requirements. Approval of the "Urban" district designation would be consistent with approved urban land use reclassifications in the immediate vicinity of Keaau. The reclassification of the site to the Urban district will not contribute to scattered spot urban development, as it is in the midst of areas with urban type uses, and is adjacent to and in close proximity to existing urban designated lands and facilities. In addition to the standards for the Urban District set forth in HAR 15-15-18, the LUC considers specific criteria in making their decision as outlined in HAR 15-15-77. Those decision-making criteria for boundary amendments and the relationship of the proposed project to them are outlined below. 1. The extent to which the proposed reclassification conforms to the goals, objectives, and policies of the Hawaii State Plan and relates to the applicable priority guidelines of the Hawaii State Plan and the adopted functional plans. 2. The extent to which the proposed reclassification conforms to the applicable district standards. 3. The impact of the proposed reclassification on the following areas of stare concern: A. Preservation or maintenance of important natural systems or habitats B. Maintenance of valued cultural, historical, or natural resources C. Maintenance of other natural resources relevam to Hawaii's economy including, but not limited to agricultural resources D. Commitment of state funds and resources E. Provision for employment opportunities and economic development F. Provision for housing opportunities for all income groups, particularly the low, low-moderate, and gap groups 4. In establishing the boundaries of the districts in each county, the commission shall give consideration to the general plan of the county in which the land is located (18) The Hawaii State Plan is a guide for future long-range development. It identifies the goals, objectives, policies, and priorities for the State; allocates limited resources; improves coordination among federal, state, and county agencies; and establishes a system for integrating all major state and county activities. The extent to which the HELCO site conforms with the Hawaii State Plan and its related functional Plans and the extent to which the project conforms with the provisions of the County General Plan are discussed in preceding sections of this report. Site investigations and reconnaissance as well as consultation with the applicable agencies revealed no significant natural resources, habitats, cultural, or historic resources at the project site. The generating station has not and will not have a significant adverse impact on any environmental resources. The reclassification of the site to the Urban district will not entail the removal of agricultural land from active production. HELCO's current full- and part-time staffing for the Puna Generating Station consists of three shifts with two employees per shift. Other HELCO staff visits the site, as required by specific tasks. The production of electricity provided by the Puna Generating Station will support the continued economic expansion of the Island of Hawaii and provide the necessary energy to support affordable housing programs as they are developed. HELCO does not require expenditures by either the State of Hawaii or the County of Hawaii. HELCO is seeking to rezone the site to the County's general industrial district (MG), with a minimum lot size of 10 acres (MG-l0a). The County's general industrial district allows uses that are consistent with the power generating use established at the Puna Generating Station. HELCO plans to continue using the site to generate electricity and for related ancillary improvements. (These are currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988.) 6. County General Plan Designation A letter dated February 3, 1997, from the County Planning Director confirms "that HELCO's Puna Generating Station is located within the area designated as `Industrial' by the General Plan Land Use Pattern Guide (LUPAG) Map." HELCO's request for both an amendment of the State Land Use Boundary to the Urban District, and the request for an amendment of the County's zoning designation to general industrial conforms with the County General Plan LUPAG map designation for the site and applicable sections of the General Plan. 7. County Zoning The site is currently designated in the County's agricultural zoning district, and is zoned A-20. (19) HELLO is seeking to rezone the site to the County's general industrial district (MG), with a minimum lot size of 10 acres (MG-l0a). The County's general industrial district allows uses that are consistent with the power generating use established at the Puna Generating Station. HELLO plans to continue using the site to generate electricity and for related ancillary improvements. (These aze currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on-November 15, 1988.) The uses permitted in the County's general industrial district do not violate the standards for the Urban District of the State Land Use Boundaries as set forth in HRS 205-2. The HELLO site is slightly over 10 acres in size. Under the current and the requested zoning, HELLO will not be able to subdivide the site. 8. Puna District Community Development Plan Community Management Associates, Inc. prepared the Puna Community Development Plan draft in June 1992. The County did not adopt the draft. 9. Special Management Area The site is not located within the area designated as the Special Management Area of the County of Hawaii, pursuant to Chapter 205A, Hawaii Revised Statutes, and applicable administrative rules of the County Planning Commission. C. PHYSICAL CHARACTERISTICS AND ENVIRONMENTAL SETTING OF THE PROPERTY AND SURROUNDING AREA Physical Characteristics/Environmental Setting 10. Description of Subject Property, Location, Climate, Topography, Slope, Soils (including size, shape, existing structures) The subject property is identified as TMK 1-6-03:93. It encompasses a total of 10.5 acres, and it has, to an extent, a triangulaz shape. The HELLO site is located at Keaau in the Puna District, County of Hawaii. The primary access to the Puna Generating Station site is from Mamalahoa Highway by Keaau Road. The site is located neaz the 300-foot elevation. The site is generally level with no significant grade or on-site undulations. The mean annual rainfall in the area ranges between 125 to 175 inches. Prior to HELLO acquiring the subject site, it was extensively disturbed by activity related [o on-site grading and fill, construction, vehicular traffic, and sugar mill and related operations. (20) HELCO owned structures and improvements on the site are related to electrical generation and distribution. In addition to HELCO's structures, the County Water Department also has two water wells, a chlorinator, storage and pump facilities, and 10- inch diameter service lines. 11. Lava Flow Hazard Zone The United States Geological Survey (USGS) has established volcanic hazard zones for the Island of Hawaii for long-term planning purposes. The lava flow hazard zone designations are based on the percentage of the potential flow area that has been covered by lava flows during specific time periods, the frequency of past eruptive events, and the assumption that the rate of current volcanic activity will continue for the next several decades. Zone 1 reflects the greatest volcanic hazard and Zone 9, the lowest. The Puna Generating Station is located within Lava Flow Hazard Zone 3, which is also the zone designation applicable to Hilo. The entire Island of Hawaii is susceptible to earthquakes originating in fault zones under and adjacent to the island. The County Building Code designates the entire Island of Hawaii as being within the Earthquake Zone 3 (based on a scale of zones with increasing risk from 0 to 4, due to seismic occurrence and danger). The Zone 3 designation requires that structural design requirements be met in conjunction with the design and construction of any structure. 12. Distance from Coastline The site is over 3 miles from the nearest coastline. 13. Agricultural Lands of Importance in the State of Hawaii (ALISH) Designation Consultation with the State Department of Agriculture indicates that the Agricultural Lands of Importance to the State of Hawaii (ALISH) system do not have an ALISH rating for the site on map H-66, dated January 1977. 14. United States Department of Agriculture, Natural Resources Conservation Services Soil Service Report Soil Type The United States Department of Agriculture (USDA) Soil Conservation Service Soil Survey Report classifies the soils in the vicinity of the site as being in the Olaa series, and specifically the Olaa Silty Clay Loam (OaC). This series is characterized by moderately deep, moderately fine soil. Permeability is rapid, runoff is slow, and the erosion hazard slight. 15. Land Study Bureau Soil Rating Consultation with the State Department of Agriculture indicates that the Land Study Bureau Detailed Land Classification, Island of Hawaii (November 1965, map 654) indicates that the site has a "U" or urban use rating, reflecting the industrial use of the (21) area. Former sugazcane lands surrounding the former Puna mill site have an overall productive rating of "C" indicating fair productivity potential for most crops. 16. Flood Insurance Rate Map (FIltM) Designation The United States Army Corps of Engineers' Flood Insurance Rate Man (FIItM) designates the site as "Zone C." Zone C is an area characterized with minimal flooding. 17. Existing Drainage Ways or Improvements A culvert adjacent to the road serving the site drains into a drainage ditch parallel to the road. Standazd on-site drainage improvements would accommodate any future intensification of the use of the site. HELCO will comply with all applicable regulations governing drainage. 18. Air/Noise/Groundwater/Water Quality a. Air Quality HELCO Generating Station is in compliance with all applicable federal and state regulations related to air quality. Appendix C is a report titled "Puna Generating Station, Air Quality Impacts," prepared by Jim Clary and Associates. b. Noise Hawaiian Electric Company (HECO) personnel measured background ambient noise levels at the Puna Generating Station. HECO's measurements indicate that the Puna Generating Station is in compliance with the State DOH 70 dBA standazd at the property lines. Title 11, Chapter 46 Community Noise Control, adopted by the State Department of Health (DOH) in September 1996. On the Island of Hawaii, the DOH regulates noise from on-site activities. State DOH noise regulations are expressed in maximum allowable property line noise limits for areas zoned preservation residential, apartmenUcommercial, and agricultural/industrial. The noise limits established for these zoning classes aze shown in Table Two. These noise limits cannot be exceeded for more than 2 minutes in any 20-minute time period. Because [he project site and surrounding areas aze located on lands zoned for agricultural use, the DOH noise limits are 70 dBA for both the daytime and nighttime periods. (22) Table Two Maximum Permissible Sound Levels in Decibels (dBA) Zoning Class A Class B Class C Residential and Apartment, Hotel, Agriculture, Time Preservation and Business Industrial Daytime (7 a.m. to 10 p.m.) 55 60 70 Nighttime (10 p.m. to 7 a.mJ 45 50 70 Notes: a) Standards shall apply [o [he following excessive noise sources: stationary noise sources and equipment related [o construction, agriculture, and industrial activities. b) Maximum permissible sound levels shall apply to any excessive noise source emanating within the specified zoning district, and a[ any point a[ or beyond the property line of [he premises. c) Noise levels shall not exceed the allowable levels for more than 10 percent of the time (Lio) within any 20-minute period, except by permit or variance issued under HAR 11-46-7 and 11- 46-8. d) The allowable noise for impulsive sound shall be 10 dBA above the values in [his table. Hawaii Administrative Rules, Title 1 Chapter 46 Construction noise also falls under permitted activities that can exceed the levels shown in Table Two for a specified period of time. There aze, however, permit restrictions for construction activities. These are: • No construction activities that produce noise levels in excess of the values in Table Two at or beyond the property line are allowed before 7 a.m. or after 6 p.m., Monday through Friday. • No construction activities that produce noise levels in e,ccess of the permissible sound levels shown in Table Two at or beyond the property line are allowed for the hours before 9 a.m. and after 6 p.m. on Saturdays. • No construction activities that exceed the noise levels specified in Table Two aze allowed on Sundays and on holidays. c. Groundwater HECO environmental department personnel support HELCO in matters related to federal and state regulation related to groundwater. FiECO indicates that the HELCO Generating Station is in compliance with all applicable federal and state regulations related to groundwater. (23) The Puna Generating Station is situated over the Keaau Aquifer System. The Hilo-Keaau region is underlain by relatively young lava flows, mostly less than 10,000 years old, from Mauna Loa. Regionally, the lavas are highly permeable, and large volumes of groundwater under low gradients pass through them. At the Puna Generating Station, all data indicators suggest that groundwater is pazabasal, and that the saturated aquifer is bounded below by an aquitard, which is probably an ash bed. Parabasal groundwater is hydraulically connected to the basal Tens but rests on a low permeability stratum rather than seawater. The estimated boundary between basal and pazabasal ground water lies about 1.3 miles east of [he Puna Generating Plant and passes through Pazadise Pazk. Parabasal groundwater is hydraulically connected [o the basal lens but rests on a low permeability stratum rather than seawater. The HELCO and DWS wells at the Puna Generating Station have never displayed salinity of more than 10 parts per million. (Source: Unpublished report tilted "Puna Water Resources Investigations and Permitting..." Mink and Yuen, Inc., September 1996.) The State Water Resources Protection Plan (Volume II Appendix, 1990, by G.A.L. Yuen and Associates) indicates that over the 8 miles between Hilo and the contact of Mauna Loan and Kilauea lavas near the Puna Power Plant, approximately 1,700 million gallons per day (mgd) of fresh groundwater flow either in a seawazd direction or southwazd into the Kilauea Aquifer Sector. The Water Resource Protection Plan indicates that for the Hilo Aquifer System, rechazge is 793 mgd and for the Keaau Aquifer System, it is 898 mgd. Estimates by Takasaki indicate that 1,000 mgd moves southward into the Kilauea Sector, leaving 700 mgd to dischazge from Mauna Loa lavas along the coast. The Groundwater Protection Plan indicates that the sustainable yields for the Hilo Aquifer System and the Keaau Aquifer System are 347 and 393 mgd, respectively. (Source: Ibid., Mink and Yuen, Inc., September 1996.) Data available from various published and public sources indicates that the current draw from the Keaau Aquifer is less then 20 mgd. Data from the State Commission on Water Resource Management indicates that the capacity of existing wells in the aquifer total 27 mgd. HELCO and the Hawaii County Department of Water Supply (DWS) have separate groundwater wells on the Puna Generating Station site. The following describes the HELCO and DWS wells and ancillary system components. • HELCO Information provided by HELCO indicates that the three HELCO wells on the generating station site use an average of 12.1 million gallons per day (mdg). HELCO uses groundwater for cooling water pumps, to cool fans, generators, the existing combustion turbine, compressors, pumps, air heater wash, various fire hoses on each floor, and all the wash-down and cooling needs. HELCO provides water to the adjacent papaya operation, which was previously owned by AMFAC, prior owner of the HELCO site. The papaya operation also uses DWS water service provided through a meter located on the generating station site. (24) During periods when HELCO's steam plant is not operating and/or when HELCO shuts down the three deep wells, the papaya operation provides HELCO county water to supply the various cooling water pumps and to meet HELCO's other water needs at the Puna Generating Station. Information provided by HELCO also indicates that use of groundwater by the Puna Generating Station has no adverse affect or impact on the underlying aquifer. Information provided by HELCO indicates that HELCO currently complies with and in the future will continue to comply with all state and federal requirements applicable to the use of groundwater. • DWS DWS has two wells on the generating station site, Olaa wells A and B. In addition, DWS has a chlorinator station and pipeline easements on the site. Water from Olaa wells A and B and water from a third DWS well, Olaa C (located a[ a site up gradient of the generating station near the former dispensary camp) is providing water to DWS customers in the Keaau-Mountain service azea. This system has a linear service area essentially following the alignment of the Volcano Highway from Keaau to Glenwood, with a side line providing service to Paradise Drive. Until Olaa well C was completed, water from Olaa wells A and B was pumped through a series of booster pumps and storage tanks to the uppermost service azea in Glenwood. DWS continues to have the capability of pumping water up gradient from Olaa wells A and B, but seeks to minimize this in order to reduce system pumping costs. Since the Olaa well C is up gradient of wells A and B, it is the primary source of water for the DWS service area. The most current data submitted to the State Commission on Water Resource Management, for the month of December 1997, indicates that DWS Olaa wells A and B pumped a combined total of 2.5 million gallons per month. Olaa C well pumped 26.4 million gallons in the same month. d. Water Quality As noted previously, the HELCO and DWS wells at the Puna Generating Station have never displayed salinity of more than 10 parts per million. (Source: Unpublished reFort tilted "Puna Water Resources Investigations and Permitting..." Mink and Yuen, Inc., September 1996.) This is attributable to the estimated boundary between basal and pazabasal ground water being about 1.3 miles east of [he Puna Generating Plant. Pazabasal groundwater is hydraulically connected to the basal lens but rests on a low permeability stratum rather than seawater. Consequently, the infiltration of seawater is minimal. As discussed in a subsequent section concerning wastewater disposal, HECO environmental department personnel support HELCO in matters related to federal and state regulation related to wastewater disposal. HECO indicates that the HELCO Generating Station is in compliance with all applicable federal and state regulations (25) related to wastewater disposal. Information provided by HECO also indicates that wastewater disposal associated with the Puna Generating Station has no adverse affect or impact on the underlying aquifer. Historic Resources: 19. Existing Archaeological, Cultural or Historic Sites on the National Hawaii Register The HELLO Puna Generating Station site has no archaeological, cultural or historic sites or structures of historical significance. This is confirmed by correspondence from the state agency responsible for archaeological, cultural or historic sites and structures. A letter dated September 21, 1988, signed by William W. Paty, Chairperson, Board of Land and Natural Resources, commenting on Special Permit Application 88-22 states, in part: "Our Department's Historic Sites Section indicates that since this application only requests continued use of the existing plant facilities, there will be "no effect" on significant historic sites." In March 1997, CH2M HILL requested a written determination from the Historic Preservation Division of the Department of Land and Natural Resources that the State Land Use amendment and County rezoning change will have no effect on any significant sites on HELCO's property. A letter dated April 14, 1997, signed by Don Hibbard, Administrator, State Historic Preservation Division, states, in part: "Because the area has been so extensively disturbed we believe that there are no significant historic sites remaining on the subject property. We thus believe that the proposed rezoning and boundary designation changes will have "no effect" on historic sites." Through the early-1980s for an unknown period of time, sugar was extensively cultivated in the area surrounding the HELLO Generating Station site and the subject site was used for sugar milling. Prior to, during the establishment of the aforementioned uses and since the establishment of HELCO's generating and related uses in 1988, there are no known traditional gathering activities and/or cultural practices as identified by Article XII, Section 7 of the Hawaii State Constitution affecting the subject property. Natural Resources: 20. Existing Flora/Faunal Resources (any native or exotic plants, any listed or candidate endangered species) a. Flora The Puna Generating Station site has been used for sugar milling for almost 100 years, and for power generation for a decade, and has been extensively disturbed. The site does (26) not have any native, listed or candidate endangered flora. Within the fenced portion of the Puna Generating Station, vegetation is composed of planted landscaping. A mixed grass fringe is found on the west, north, and east sides of the site. The mixed grasses are all introduced such as California, molasses, and elephant grasses; a mix of weedy species; and some garden escapees such as avocado. b. Fauna CH2M HILL consulted with the United States Department of the Interior, Fish and Wildlife Service (USFWS), Pacific Islands Ecoregion. An April 24, 1998 letter from a representative of indicate that the Hawaiian hawk, `Io (Buteo solitarius), and the Hawaiian hoary bat, Ope`ape`a (Lasiurus cinereus semorus), have been sighted in the proximity of the Puna Generating Station. The letter goes on to state: "No significant adverse impact to fish and wildlife resource are expected to result from the proposed zoning change." Based on on-site observations, the only known rare or endangered native avian resource that has been identified is native migratory specie, the Hawaiian Stilts (Himanropus mexicanus knudseni), observed on the edge of a small puddle adjacent to the main paved driveway into the generating station. The puddle is not a habitat area for the Hawaiian Stilts. This species is listed as endangered by the USFWS and by the State of Hawaii Division of Forestry and Wildlife. Based on on-site observations, the only known rare or endangered native mammalian resource that has been identified at the generating site is the Hawaiian hoary bat, Ope'ape'a (Lasiurus cinereus semotus). This species is listed as endangered by USFWS and by the State of Hawaii, DLNR Division of Forestry and Wildlife. At night, the bats feed on flying insects attracted by night lighting. The generating station site and structures are not a habitat area for the bat. 21. Scenic or Coastal Resources There are no scenic or coastal resources affected by the HELCO site. The Natural Beauty element of the County's General Plan identifies sites or areas that are considered to be a scenic resource. The HELCO site and immediately surrounding area are not listed as a scenic site. The site is over three (3) miles from the nearest coastline, and does not affect coastal resources. Social-Economic Characteristics: 22. Socia] Settlement Pattern for the Area Keaau is located at the junction of two major highways in Puna, and is thus centrally located. A central commercial area with surrounding "pockets" containing concentrations of people characterizes Keaau's settlement pattern. The area immediately surrounding the HELCO site has a mix of urban types of land uses in the vicinity of the site. The HELCO (2~) site and surrounding area's settlement pattern is historically and functionally an extension of the Keaau Town center's urban area. The state has approved urban land use reclassifications in the immediate vicinity of Keaau. Approximately 660 acres of land were included in a 1994-land use boundary amendment. With subsequent county rezoning, the amendment will lead to an expansion of Keaau village over time, as infrastructure is developed and as the market demand for urban uses materializes. The expansion includes a pazcel north of Keaau is on the western side of the Mamalahoa Highway, on the opposite side of the highway from the HELCO site. (The reclassification of the 600 acres of land involves land owned by W. H. Shipman, Limited. The 600 acres is a portion of approximately 2,000 acres in and azound Keaau, which Shipman has planned as part of the "Conceptual Keaau Development Plan." Shipman proposes to develop the 2,000 acres over a period of 20 or more years.) As discussed in section 25, "Land Use," several urban uses have been established in the immediate vicinity of the Puna Generating Station. The County Planning Commission has approved Special Permits for several pazcels in the vicinity of the HELCO site. The Special Permits allow urban type uses that include a flower packing facility, a papaya packing facility, and a church school. Sites with urban uses in some proximity to the HELCO also include astate-assisted housing project, permitted under statutory pre- exemptions of land use requirements, and a former sugar plantation housing subdivision. Section 25 also discusses TMK 1:6:03:5, a pazcel immediately adjacent to the Puna Generating Station. In 1997, the County approved redesignation of a 14.3 acre portion of TMK 1:6:03:5 to the Urban District and concurrently rezoned the aforementioned area to alight industrial (ML) zoning district designation. Subsequent to the 1997 rezoning approval, the property owner submitted a second rezoning application, now pending final County Council action. The pending rezoning seeks to change the ML zoning district designation to the "Industrial-Commercial Mixed" (MCX) district designation. The MCX zoning district was created in late-1996 and would allow a mix of commercial and light industrial uses. Urbanization of the HELCO Puna Generating station will not contribute to scattered spot urban development, as it is in the midst of azeas with urban type uses, and is proximal to existing urban facilities. 23. Economic Resources of the Area Historically, the Puna District has had agricultural activities as the primary economic activity. Through the 1980s, sugar provided significant employment in the district. With the termination of sugaz cultivation, diversified agriculture has been the principal primary economic activity located in the district. Industrial activities in the Puna District aze limited, and include processing of agricultural products, electric power production, and activities located at the Shipman Industrial Pazk. (28) Tourism in the Puna District is limited, with the principal tourist destination being the Volcanoes National Park. The employed residents of the towns and subdivisions in the Puna District generally work in Hilo. The largest of these [owns is Keaau, followed by Pahoa. Both of these towns serve as commercial and service centers for residents of the Puna District. 24. Land Values The Puna District's residential lands offer some of [he lowest cost house lots in the state. The low cost of residential lots is attributable to the supply of unimproved residential lots in the Puna District exceeding the demand for undeveloped lots. The excess of supply relative to demand keeps the price of unimproved lots depressed. Commercial and industrial land values aze typically lower in the Puna District than in Hilo. This is attributable to Hilo having a larger population base and being closer to transportation facilities, such as the Hilo airport and harbor. Since the Puna Generating Station is apre-existing facility, any impact that the generating station would have on surrounding land values would have already occurred and be reflected in current property values. HELCO does not contemplate selling the Puna Generating site at any time in the foreseeable future. Surrounding lands: 25. Land Use Keaau is located at the junction of two major highways in Puna, and is thus centrally located. A central commercial area with surrounding "pockets" containing concentrations of people chazacterizes Keaau's settlement pattern. The area immediately surrounding the HELCO site has a mix of urban types of land uses in the vicinity of the site. The HELCO site and surrounding area's settlement pattern is historically and functionally an extension of the Keaau Town center's urban area. A property immediately adjacent to the HELCO site, identified by TMK 1:6:03:5, was subject of County land use approvals in 1997. A County land use boundary amendment, approved in 1997, reclassified a 14.3 acre portion of TMK 1:6:03:5 to the state Urban District boundary, with the rest of the parcel remaining in the state Agricultural District. TMK 1:6:03:5 was concurrently rezoned in 1997 to a three-acre minimum lot size agricultural zoning designation, with the Urban portion of the property rezoned to a three- acre minimum lot size limited industrial district zoning designation. Subsequent to [he 1997 rezoning approval, the property owner submitted a second rezoning application to reclassify the property to two new zoning district designation that were created pursuant to County's revised zoning ordinance enacted December 7, 1996. The second rezoning (29) request, currently pending County Council action, seeks to reclassify the portion of the TMK 1:6:03:5 in the state's Agricultural District to the County's "Family Agricultural" (FA) zoning district, with a minimum lot size of three acres. The 1998 rezoning requests that the remaining 14.3 acres in the state's Urban District be reclassified to the County's "Industrial-Commercial Mixed" (MCX) district designation, with a minimum lot size of 20,000 square feet. The FA zoning district is an agricultural zoning district designation, and the MCX zoning district allows a mix of commercial and light industrial uses. The County Planning Commission has also approved Special Permits for several other parcels in the vicinity of the HELCO site. The Special Permits allow urban type uses that include a flower packing facility, a papaya packing facility, and a church school. Sites in some proximity to the HELCO with urban uses also include astate-assisted housing project, permitted under statutory pre-exemptions of land use requirements, and a former sugar plantation housing subdivision. 26. Zoning The site HELCO is currently designated in the County's agricultural zoning district. The site is currently zoned A-20. HELCO is seeking to rezone the site to the County's general industrial district (MG), with a minimum lot size of 10 acres (MG-l0a). HELCO wants to rezone the site from an agricultural zoning designation to the County's general industrial designation, as the current use of the site is consistent with the uses permitted under the general industrial zoning district designation. HELCO plans to continue using the site to generate electricity and for related ancillary improvements. (These are currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988.) D. PUBLIC FACILITIES AND SERVICES 27. Description of Access The primary access to the Puna Generating Station site is from Mamalahoa Highway via Keaau Road. Mamalahoa Highway (State Route 11, elsewhere referred to as Route 19 and 190 and also known as Hawaii Belt Road) is a major arterial serving most of the Island of Hawaii. Wi[hin the vicinity of the HELCO site, Mamalahoa Highway is afour- lane highway that runs generally in the north-south direction. Keaau Road is a private road providing access from Old Volcano Road to the existing HELCO Generating Station. The two-lane Old Volcano Road runs parallel and east of Mamalahoa Highway. Keaau Road crosses Old Volcano Road. (30) 28. Availability of Water Water is available at the HELCO Puna Generating Station site. Both HELCO and the Hawaii County Department of Water Supply (DWS) have separate groundwater wells on the site. Section 18-c, concerning "groundwater," contains an extensive discussion on the topic. 29. Wastewater Disposal HECO environmental department personnel also support HELCO in matters related to federal and state regulation related to wastewater disposal. HECO indicates that the HELCO Generating Station is in compliance with all applicable federal and state regulations related to wastewater disposal. Information provided by HECO also indicates that wastewater disposal associated with the Puna Generating Station has no adverse affect or impact on the underlying aquifer. Information provided by HECO indicates that the Puna Generating Station has four existing wastewater flows, described below. • Non-contact condenser cooling water, discharged from the condenser comprises approximately 467,000 gallons per hour (gph). This water is discharged into a re- injection well located off-site, and is permitted by underground injection control (UIC) permit No. LTI-I 1438. • Auxiliary cooling water discharge comprises approximately 9,300 gallons per hour (gph). Currently, this water is disposed into aditch/culvert and discharged off-site. HELCO indicates it is considering a plan to isolate and recycle (i.e., re- circulate) all flows out of the existing auxiliary cooling water pumps through a service water cooler. • Currently, sanitary wastewater cesspool discharge comprises approximately 30 gph. • Industrial wastewater discharge varies. Industrial wastewater receives primary treatment at the Puna Generating Station, and is [hen trucked to the Hill Generating Station in Hilo. It is further treated at the Hill Station and discharged to the Hill facility's injection wells, pursuant to existing UIC permits iJII 1241 and UH 1242. 30. Solid and Hazardous Wastes The County does not provide solid waste pickup service. The County of Hawaii has a transfer station in the vicinity of Keaau. The Hilo Landfill will be replaced by the West Hawaii landfill at Puu Anahulu. Solid waste generated by HELCO at the Puna Generating station is recycled to the extent practicable, with the remainder being disposed of at the County landfill. HELCO Generating Station is in compliance with all applicable federal and state regulations related to the disposal of solid waste. (31) Waste identified as hazardous is disposed of in accordance with federal and state regulatory requirements. Currently, hazazdous waste from the Island of Hawaii is shipped to the U.S. mainland for disposal. 31. Police and Fire Protection The HELCO site does not impact the demand for police and fire protection. Stations located in both Keaau and Hilo provide county police and fire protection services. HELCO personnel aze also trained for emergency situations including fires and first aid. As noted elsewhere, a chain link fence surrounds the HELCO site. 32. Schools The HELCO site does not impact the demand for schools. The State Department of Education is currently constructing separate elementary and high schools in the immediate vicinity of Keaau. 33. Parks The HELCO site does not impact the demand for pazk space. The County's Shipman Park currently serves the azea. Either the development of separate park sites or expansion of the existing Shipman Park will accompany expansion of Keaau. 34. Other Utilities and Services (telephone/electricity) The Puna Generating Station is an essential element of HELCO's electrical power generation capacity for Hawaii Island customers. HELCO provides electrical service to the Puna Generating Station site. The HELCO site does not impact the demand for telephone service. GTE Hawaiian Telephone serves the HELCO site and surrounding azea from its Keaau station. E. ENVIRONMENTAL ASSESSMENT AND ANALYSIS 35. Relationship Between Local Short Term Uses of Environment and Maintenance and Enhancement of Long Term Productivity Short-term uses of the biophysical components of the environment include direct construction-related disturbances and direct impacts associated with an increase in activity that occurs in less than 5 years. Long-term uses of the environment include those impacts occurring over a period of more than 5 yeazs, including permanent resource loss. No short-term changes are anticipated at the HELCO Puna Generating Station that will impact components of the environment. Through the year 2017, no long-term changes are anticipated at the HELCO Puna Generating Station that will impact components of the environment. (32) Beyond the year 2017, and under unforeseen circumstances prior to the year 2017, the Puna Generating Station's generating capacity may be expanded. One impact associated with possible future expansion of the generating capacity is the change in the visual environment. A second impacts associated with any future expansion are related to air emissions produced by the facility decreasing the criteria pollutant increments available for future new sources under the Prevention of Significant Deterioration (PSD) regulations. Electrical energy is a resource that has become an indispensable part of life. Electric utility companies have the responsibility of providing reliable electric service at a reasonable cost to the consumer. Every effort should be made to conserve electricity, and new sources of energy production also need to be developed. As it becomes older, equipment runs less efficiently, uses more natural resources, and results in higher costs to the user. On the Island of Hawaii, population increases and the planned retirement of older equipment are creating the need for additional electrical generating capacity. The population of the Island of Hawaii has grown dramatically over the last two decades. Overall population and economic growth on the Island of Hawaii is expected to continue in the foreseeable future. 36. Mitigate Measures Proposed to Avoid, Minimize, Rectify or Reduce Impact No development is currently planned or proposed in conjunction with the requested changes in the state and County land use designations. Since no development is currently planned or proposed, there are no impacts to reduce, minimize and rectify. Therefore, no mitigation measures are proposed. 37. Alternatives to the Proposed Development No development is currently planned or proposed in conjunction with the requested changes in the state and County land use designations. Since no development is cwrently planned or proposed, alternatives are not relevant. 38. Irreversible and Irretrievable Commitments of Natural Resources Involved if Proposed Action Implemented Irreversible and irretrievable resource commitments are related to the use of nonrenewable resources and the effects that use of these resources will have on future generations. Irreversible effects primarily result from use or destruction of a specific resource (for example, energy and minerals) that cannot be replaced within a reasonable time frame. Lretrievable resource commitments involve the loss in value of an affected resource that cannot be restored as a result of the action (for example, extinction of a threatened or endangered species). The Puna Generating Station is an existing use on a site that has been actively used for power production over the past decade, and for sugar milling prior to that. No new development is currently planned or proposed in conjunction with the requested changes (33) in the state and County land use designations. Since the HELCO Puna Generating Station is an existing use and development, and no new use or development is currently planned or proposed, there will not be any additional irreversible and irretrievable commitment of natural and fiscal resources. HELCO's decision to continue the use of diesel fuel, rather than other fuel sources, is based on the economics of providing the electricity. HELCO is committed to the development of feasible, cost-effective alternative fuels and power sources and increased conservation measures to lessen dependency on imported fossil fuels. F.

(ATA) to Identify the traffic impact of the existing Hawaii Electric Light Company's (HELLO) Puna generation facility, identified as (TMIq: 1-6-03:93. HELLO is presently requesting to rezone the site of the Puna generation facility at the County level from agricultural use to industrial use and at the State level from agricultural use to urban use. Initially, the Puna Generating Station was developed as an ancillary use with the operation of the former Puna Sugar Mill; this activity was previously permitted as agricultural activity. The generated electricity was utilized by sugar operations and employee-residents. With the cessation of sugar operations, HELLO acquired suffiGentright-of-way and was granted a Special Permit by the County of Hawaii to continue the generation of power. The Specal Permft was required since the power generation became the primary use for the site as ft was no longer assodated wtth agricultural activity. The requested State and County rezonings would better reflect the actual use of the Puna generation faclifty sfte. . The site of the existing fadifty is located at the former Puna Sugar MiII. Primary axes to the sfte is Nom Mamatahoa.Highway via Keaau Road. Flgure 1 shows the general roadway system in the vidnfty of the proposed expansion site. The existing facility has 37 MW of generating capacriy: The statfing of the fadlity insists of 3 shifts with 2 employees per shift. The delivery of diesel fuel is currently 21-49 trips per week. HELLO currently has no expansion plans for the facilities located at the Puna generating tacility. pERY TO- OFFICES IN 60. 6UMNEii STREET. 6UITE 521 HONOLULU. HGWgII 96617.503. I HONOLULU.

MgUI, HgWgll ~1~ pU6 erva euaoweens ac wovCa~.irvc Mr. AI Lono Lyman CH2M Hill May 11, 1998 Purpose and Scope The purpose of the study is to analyze the traffic impacts of the existing HELCO facility on the local roadway system. The following are traffic scenarios which are analyzed in this study: • Existing Year 1997 Conditions • Year 2001 Base Conditions This study analyzes the two Intersections of Mamalahoa Highway at Keaau Road and Old Volcano Road at Keaau Road, which are directly affected by the HELCO facility traffic. EXISTING CONDITIONS The following is a brief discussion of the existing major roadways in the immediate vicinity of the expansion site, and the current traffic operating conditions at the two key intersections. Mamalahoa Hi hwa -Mamalahoa Highway (State Routes 11, 19 and 190), also known as Hawaii Beit Road, is a major arterial serving most of the island of Hawaii. Within the vicinity of the HELCO expansion site, Mamalahoa Highway is a four-lane highway which runs generally in the north-south direction. North of Keaau Town, Mamalahoa Highway is a divided highway with a posted speed limit of 55 miles per hour (mph). Within Keaau Town, Mamalahoa Highway is an undivided, four-lane highway with a reduced speed limit of 35 mph. Keaau Road -Keaau Road is a private road providing acx;ess from Old Volcano Road to the existing Hf3C0 generation fadlity. Between Mamalahoa Highway and Old Volcano Road (approximately 50 feet), Keaau Road-is maintained by the County: of Hawaii. The two-lane gravel road also serves a Ifght IndusVfal complex located Just north of the HELCO tadlriy. Keaau Road Is oonVOiled by stop signs at the Intersections at Old Volcano Road and Mamalahoa Highway. Old Volcano Road - Within the general vidnity of the study area, thetwo-lane Old Volcano Road runs parallel and east of Mamalahoa Highway. North of Keaau Road, the Old Volcano Road serves a light industrial complex and private properties. South of Keaau Road, the Old Volcano Road provides access to the residential areas of Keaau Town. Figure 2 shows the existing geometries at two analyzed intersections. Weekday AM and PM peak period traffic counts were conducted by ATA at the two existing analyzed Intersections. Figure 3 shows the existing traffic volumes at the two -2- AUSTIN. T6UT6UM1 6 A660CIATE6. INC. CNIL ENOtlVEER6 EWVEVOR9 Mr. AI Lono Lyman CH2M Hill May ti, 1998 intersections. Manual turning movement counts were conducted during the morning and evening peak periods on March 19 and 20, 1997. During the morning AM peak period, the peak direction of traffic flow on Mamalahoa Highway is in the northbound direction with approximately 2,640 vehicles during the peak hour and approximately 640 peak hour vehicles in the southbound direction. During the afternoon PM peak period, the peak direction of flow is in the opposite direction with approximately 1,800 peak hour vehicles in the southbound direction and approximately 770 peak hour vehicles in the northbound direction. It was observed that, during the PM peak period, a relatively high number of southbound vehicles (267 vph) on Mamalahoa Highway turn left onto Keaau Road and then turn right onto the Old Volcano Road. It is assumed that most of these motorists are bound for the residential areas of Keaau Town. Based on the existing traffic count data, the number of vehicles that utilize Keaau Road serving the HELCO facility area is relatively low. During the AM peak hour, only 46 vehicles per hour (vph) were observed, with 12 vph in the westbound direction and 34 vph in the eastbound direction. During the PM peak hour, only 33 vph utilize Keaau Road with 27 vph in the westbound direction and 6 vph in the eastbound direction. Level of service (LOS) is a qualitative measure used to describe the conditions of traffic flow, ranging from free-flow conditions at LOS A to congested conditions at LOS F. The 1994 (Jiahway C~~dty Manual - Snedal Report 209 method for calculating delays and corresponding levels of seMce at stop-controlled Intersections was utilized in this study. Level of service definitions for signalized and stop~ontrolled Intersedions are provided In Table 1. Figure 3 also shows the levels of service at the two existing intersedions. Results also showthat, during the AM peak hour, the southbound left tum movementfrom Mamalahoa Highway to Keaau Road is operating at LOS F. Long delays to this particular movement are mainly due to the high amount of northbound opposing vehldes on Mamalahoa Highway. The westbound left-tum movement from Keaau Road to Mamalahoa Highway is also operating at LOS F during the AM peak hour, but this only affects a small number of vehldes (only one vehicle during the peak hour was observed). The remaining movements at both Intersections are all operating at acceptable levels of service (LOS A, B, C or D). -3- ~T/ AU6TIN. TBUT6UM~ 6 485pCIGTE6. ANC CNIL ENfiMIEERB fiUpVEY°R6 Mr. AI Lono Lyman CH2M Hill May 11, 1998 Results also show that during the PM peak hour, only the westbound left-turn from Keaau Road to Mamalahoa Highway is operating at an undesirable level of service (LOS F). However, similar to the AM peak hour, only one vehicle during the PM peak hour was observed affected. Although the number of PM peak hour southbound left-turn vehicles (267 vph) from Mamalahoa Highway to Keaau Road is much higher than the AM peak hour (122 vph), this movement is operating at an acceptable level of service (LOS B) due to the much lower number of northbound opposing vehicles. The intersection of Old Volcano Road and Keaau Road is operating at LOS A and B during the AM and PM peak hours, respectively. YEAR 2001 BASE CONDITIONS The Year 2001 Base forecast of traffic conditions is based on existing traffic volumes plus expected ambient growth in traffic caused by regional growth throughout the entire island of Hawaii. The ambient traffic growth rate, which was applied to existing traffic volumes to estimate Year 2001 traffic volumes, is based on historical traffic counts conducted by the State of Hawaii, Department of Transportation (HDOT). Based on historical HDOT traffic counts in the vicinity of the proposed expansion, an approximate 1°~ per year traffic growth rate is applied. The resulting Year 2001 Base traffic volumes and level of service results are shown on Figure 4. Since Year 2001 operations at the Puna generation facility are not expelled to change, the future traffic generation of the HELCO facility would remain the same as the existing trip generation as given in Table 2. With the expected overall traffic growth in the area, the level of service results are similar to the existing 1997 operating conditions. The westbound left-tum from Keaau Road to Mamalahoa Highway will continue to operate at LOS F during both.the AM and PM peak hours, and again, only a small number of vehides will be affected. The southbound left- tum trom Mamalahoa Highway to Keaau Road will continue to operate at lAS" F during the AM peak hour while the PM peak hour level of service will deteriorate from LOS B to LOS C, which is still within the acceptable range. Table 3 summarizes the level of service results. CONCLUSIONS AND RECOMMENDATIONS At the Intersection of Mamalahoa Highway and Keaau Road, the southbound left-turn movement is currently operating at LOS F during the AM peak hour. This Is due to the fact that the opposing northbound traffic volume on Mamalahoa Highway (Hilo bound) Is very high during this time of day. Also, the westbound left-turn movement from Keaau -4- nl n AUSTIN, TBUT6UM1 6 A660CV1TE6. WC. pVK ENOINEERE BVRVEVpR6 Mr. AI Lono Lyman CH2M Hill May ti, 1998 Road to southbound Mamalahoa Highway is operating at LOS F during both the AM and PM peak hours. However, it should be recognized that only a small number of vehicles is being affected (only 1 vehicle was observed during both the AM and PM peak hours). Based on historical growth trends in the area, traffic volumes are expected to increase by approximately 1% per year. In the Year 2001 Base forecast, the peak hour operations at both intersections are expected to be similar to existing Year 1997 operating conditions. It is recommended that no improvements are necessary at the intersection of Mamalahoa Highway and Keaau Road. Although the westbound left-turn is currently operating at an undesirable level of service, only a very small number of vehicles are affected. And, although the southbound left-turns from Mamalahoa Highway to Keaau Road are operating at an undesirable level of service, this only occurs during the morning peak period when the opposing northbound approach is heavy. Based on the traffic counts conducted, most of these vehicles are bound for Keaau Town which can also be accessed by Ahoa Street and Kalapana Road further south.

Existing Conditions 1.1. Topography The Puna Generating Station is located on the Island of Hawaii in the easterly part of the Island, which is referred to as the Puna area. The station is located about 16 kilometers (km) south of Hilo, near the town of Keaau. About 16 km west of the Pacific Ocean, it is located in the upper Waiakea forest reserve. Other than sparse pockets of development, abandoned sugar cane fields surround the generating station. Terrain in the area can be described as mountainous due to the proximity of Mauna Loa Volcanic Mountain. Terrain elevations in this area range from 61 meters (m) near the Pacific Ocean to 570 m above mean sea level (MSL) within a 13-km radius of the facility. The elevation of the Puna facility is approximately 67 m above MSL. 1.2. Meteorology/Climate The Island of Hawaii is located in the trade wind band, a region in the north Pacific, dominated by a semi-stationary high pressure center north of Hawaii. Wind circulation around the high pressure area is clockwise and outward from the center. The trade winds come to Hawaii from the northeast to the east with the orographic channeling effect in some locations modifying the intensity and direction of the winds. In general, the trade winds are more persistent in the summer than in the winter (frequencies average 90 and 50 percent, respectively) and stronger in the afternoon than at night. At night the wind direction becomes variable and blows out of the mountains. This difference is due to the presence of the island's two largest mountains, Mauna Kea and Mauna Loa. The island terrain influences the climate with rainfall amounts varying with elevation and location and the effect of the persistent northeasterly trade winds. The Puna area receives between 130 inches of rain near the coastline and as much as 200 inches of rain in the uppermost elevations surrounding the fadlity. The annual average temperature is 23.1 degrees C, with an average daily maximum of 27.3 degrees C and the daily minimum of 21.8 degrees C (HECO 1972). On~fte meteorological data are one of the required Inputs for dispersion modeling. HELCO began collecting these data (ndudng wind speed and wind direction) on February 5, 1996. The monitoring station, Site 033, is located approximately 1.8 km west southwest of the Puna Generating Station. The monitoring station was operated in compliance with U.S. Environmental Protection Agency (EPA) guidelines. The wind rose for Site 033 is shown in Fgure 12-1. The distnibution displays the expected bi-modal distribution and not the normal trade wind characteristics. The winds blowing from the east are primarily daytime, while the winds from the northwest are nighttime drainage winds from the higher terrain. 1.3. F~cisting Air Quality The Puna Generating Station ambient air and meteorological postconstruction monitoring program was located at a station located approximately 1.8 km west southwest of the Puna Generating Station. The monitoring station is located in the area of maximum modeled impacts from the Puna Generating Station. Therefore, the air quality data are representative of the current air quality including the existing Puna Station. The monitoring station provided data for r sulfur dioxide (SOZ), particulate matter less than 10 microns in diameter (PM,a), nitrogen dioxide (NOz), carbon monoxide (CO), and ozone (03) from January 1993 through December 1993. Table 1.3-1 shows the resulting air quality data as well as the percent of data recovery. The data collected at the monitoring station confirm that the operation of the existing Puna Generating Station does not cause an exceedance of the State Ambient Air Quality Standards (SAAQS) or the National Ambient Air Quality Standards (NAAQS). The worst air pollution episodes experienced on the Island of Hawaii are the result of volcanic eruptions. Visibility is reduced by the presence of fine particulate resulting directly from volcanic activity and, secondarily, from forest fires caused by ensuing lava flows. In addition, there can be substantial increases in the ambient concentrations of sulfur dioxide and a number of toxic pollutants, such as heavy metals, during volcanic events. 2. Applicable Federal Regulations Emissions of air pollutants are regulated at the federal level pursuant to the Clean Air Act (CAA). The following are some of the major provisions of the CAA that potentially apply to any future expansion of the Puna Generating Station's generating capaicity: • National Ambient Air Quality Standards (NAAQS) • New Source Review (NSR) - Prevention of Sign'rficent Deterioration (PSD) Program - Nonattainment NSR Regulations • New Source Performance Standards (NSPS) • National Emission Standards for Hazardous Air Pollutants (NESHAP) • Good Engineering Practice (GEP) Stack Height Provisions 21. National and State Ambient Air Quality Standards The EPA has established two types of NAAQS spedtying maximum acceptable pollution levels for outdoor air. The standards are designed with a margin of safety to protect the most sensitive individuals of the population. Primary standards set limits that protect public health. Secondary standards protect public welfare. These standards must be attained in all areas that are accessible to the general public. The seven criteria pollutants for which NAAQSs have been established are: sufur dioxide (SOS, nitrogen dioxide (NO~J, carbon mono~ade (CO), ozone (03), particulate matter less than 10 microns (PM,o), particulate matter less than 2.5 microns (PMT) and lead (Pb). Hawaii's State Ambient Air Quality Standards (SAAQS) for sulfur dio~ade and PM,a are similar to the federal NAAQS. The state has more stringent standards for carbon monoxide, ozone, and nitrogen dioxide. The state standards for other criteria pollutants are identical to the NAAQS except that the state has made no distinction between primary and secondary standards and that 2 Hawaii also has an additional standard for hydrogen sulfide (HZS). Table 2.1-1 shows the federal and state ambient air quality standards. 2.2. New Source Review PSD regulations (40 Code of Federal Regulations [CFR] 52.21) apply to major stationary sources located in areas meeting the NAAOS. The PSD regulations define a major stationary source as any source that belongs to a list of 28 categories that have the potential to emit 100 tons per year (TPI~ or more of any pollutant regulated under the CAA, or any other source type that has the potential to emit pollutants in amounts equal to or greater than 250 TPY. The Puna Generating Station is classified as a major stationary source. if a modification to an existing major source is located in an area in compliance with the NAAOS, a PSD review is required for all pollutants that have the potential for signirficant increases in emissions because of the modification. Because the Puna area is designated either attainment or unclass'rfiable for all the NAAOS, a PSD review will be required for all pollutants that show a significant increase. The PSD regulations require states to designate all geographic areas into one of three classes: • Class I applies to those areas where practically any deterioration in air quality would be significant. • Class II applies to areas where moderate, well-controlled and well-sited industrial growth would be permitted. • Class III applies where industrial areas would be allowed to experience the greatest degree of air quality deterioration. Pollutant-spedfic PSD review includes: • Application of Best Available Control Technology (BACT) • Analysis of ambient air quality impacts from the project (PSD Class II and ambient) • Analysis of air quality and visibility impacts on Class I areas • Analysis of the Impact on things such as soils, vegetation, and visibility that are affected diredly as a resuk of air emissions from the projed and general commerdal, residential, and other growth assodated with the project. The State of Hawaii Department of Health (DOH) has designated the Puna area as Class II. The closest Class I area is the Volcanoes National Park, located approximately 14.4 miles southwest of the project. The Class I and Class II PSD increments and the NAAOS/SAAOS for sufur dioxde, nkrogen dioxde, PM/PM,o, and carbon mono~ade are presented in Table 2.2-1. The sign cant impact levels for sulfur dioxide, nkrogen dioxde, carbon monoxide, and PM/PM,o are also presented. Hawaii's attainment status for all criteria pollutants means that the nonattainment regulations do not apply to any future expansion of the Puna Generating Station's generating capaicity:. 3 2.3. New Source Performance Standards The NSPS are a set of national emission standards that apply to new, modified, or reconstructed stationary source categories. One of these standards, subpart GG includes the emission limitations that apply to a new, oil-fired combustion turbine. Specifically, that subpart requires: • Sulfur dioxide - 0.015 percent sulfur dioxide in the exhaust gas at 15 percent oxygen, or 0.8 percent sulfur fuel by weight, and • Nitrogen oxide - 75 parts per million (PPM) in the exhaust gas at 15 percent oxygen and on a dry basis. Any future expansion of the Puna Generating Station's generating capaicity: would comply with these standards. DoH regulations (Section 11-60.1-38(b)) limit the fuel sulfur content to 0.5% by weight for fossil fuel fired power and steam generating facilities having a power generating output in excess of 25 MW or a heat input greater than 250 MM BTU/hr. 2.4. National Emission Standards for Hazarcious Air Pollutants The NESHAP regulations currently do not apply to the Puna Generating Station since hazardous air pollutant standards for fossil-fuel-fired power plants have not been developed by EPA. 2S. Good Engineering Practice Stack Height Provisions The federal guidelines for GEP stack height apply to the project. These guidelines identify design criteria acceptable to regulatory agencies to establish a method for determining the stack height that will minimize the influence of nearby structures on normal plume dispersion. 3. Applicable Hawaii Regulations In addition to the federal regulations, the State of Hawaii regulates air pollution under Hawaii Administrative Rules (HAR), Title 11, Chapters 59 and 60.1; Hawaii State Ambient Air Quality Standards (SAAQS); and Hawaii Air Pollution Control Rules, respectively. Hawaii's State Ambient Air Quality Standards (SAAQS) for sufur dioxide and PM,o are similar to fhe federal NAAQS. The state has more stringent standards for carbon mono~ade, ozone, and nitrogen dioxide. The state standards for the other criteria pollutants are identical to the NAAQS except that the state has made no distinction between primary and secondary standards. Hawaii also has an additional standard for hydrogen sulfide (HZS). The SAAQS are shown in Table 2.1- 1. 4. Project Impacts Detailed estimates of the air quality impacts assoaated with any future expansion of the Puna Generating Station's generating capaicity: would typically be calculated by conducting an air quality dispersion modeling analysis. While that level of analysis is beyond the scope of this impact evaluation, such an analysis will be conducted for and included with the CSP/PSD application to be submitted to the Hawaii Department of Health. That analysis will meet the a requirements of federal and state air qualify regulations. The following paragraphs describe how that modeling analysis maybe performed. The potential ambient air quality impacts of any future expansion of the Puna Generating Station's generating capaicity: are determined by means of dispersion modeling. EPA-approved models will be used in the air quality analysis. The choice of appropriate dispersion modeling methods for evaluating the air quality impacts for the any future expansion of generating capacity is governed by EPA's modeling guidelines (40 CFR Part 51, Appendix W) and the topography of the site area. The area surrounding the site consists of both simple and complex terrain, i.e., the terrain heights are below stack height in some areas and above stack height in others. Therefore, a model with the ability to perform calculations in both simple and complex terrain will be used. Two EPA-approved models, ISCST3 and ISC_RTDM, can perform the calculations. Either model is suitable for the air quality analysis. ISCST3 contains COMPLEXI (an EPA- approved complex terrain model) and ISC_RTDM contains RTDM which is also an EPA approved complex terrain model. Both ISCST3 and ISC_RTDM implement the EPA Intermediate Terrain Guidance. An analysis of potential visibility impairment will be evaluated using the EPA guideline model VISCREEN. The computer models will be used along with the complete year of on-site meteorological data to estimate air quality in the vicinity of the power plant when the facility is operating at its maximum proposed emission rate. The modeled impact of the project will be compared with various regulatory threshold concentrations. The purpose of the modeling is to demonstrate that the operation of any proposed expansion of the HELCO Puna facility will not cause or contribute to a violation of any PSD increment or ambient air quality standard. The following is a list of the principal elements of the air quality impact assessment to be included in the CSP/PSD application: • Identifying the worst-case scenario, • Determining the impact area based on worst-case operating scenario, • A PSD Class I Increment consumption analysis including visibility and air quality Impacts, • A PSD Class II Increment consumption analysis, • NAAQS and SAAQS assessment, • Nontxiteria pollutant anatysls, and • Other potential air quality impacts (such as soils, vegetation, and visibility). 4.1. Construction Air Emissions Construction of the any future expansion of the Puna Generating Station's generating capaidty: would produce two types of emissions: (1) exhaust from vehicles and construction equipment and (2) dust generated during site excavation and equipment movement. Equipment exhaust emissions would be small, localized and transient. Dust emissions would be controlled by watering the site during dry or windy periods. 5 4.2. Operational Air Emissions Although no modeling has been performed for any future expansion of the Puna Generating Station's generating cepaiaty:, recent modeling of the existing Puna Generating Station has been performed for CSP application # 0235-01. This modeling includes the impact of the existing Puna Generating Station sources. Emission rates for the existing Puna sources are shown in Table 4.2-1. The modeling analysis demonstrates that predicted concentrations for the existing Puna Generating Station are below the NAAOS and SAAOS. The modeling of the existing CT-3 and boiler at Puna provides a general estimate of the location and magnitude of maximum impacts that may be expected from a new combustion turbine and boiler. The EPA guideline dispersion model ISCST3 was used to calculate maximum concentrations of combustion pollutants that would potentially result from the existing Puna Generating Station. The following information was used to predict the maximum ground-level concentrations of air pollutants from the Puna Generating Station: • A full year of Hilo airport meteorological data • The currently permitted sources of emission rates as defined in CSP application # 0235- 01,which includes CT-3 and a boiler • The existing facility configuration GEP analysis. The modeling analysis predicted the maximum ground-level concentrations for nitrogen dioxide, sulfur dioxide, PM,p, and carbon monoxide. The modeling assessment only included sources from the Puna Generating Station. All predicted concentrations were well below the corresponding NAAOS and SAAOS. The SOZ 24-hour modeling results showed the highest percent of the standard at 53.3%. Most other modeling results were less than 17% of their respective standard. CO, NO2, and annual PM,o maximum impacts were located 2 to 3 km southwest of the facility in complex terrain. SOZ and short term PM,o maximum impacts were located within 0.5 km of the faality in intermediate terrain. 4.3. Imparts on Soils, Vegetation, and Visibility Federal Primary Air Quality Standards are based on protection of human health. Federal Secondary Air Quality Standards (which in most cases are no less stringent than primary standards) are based on human 'S~velfare; which indudes such consideratioru as impacts to vegetation, animals, visibility, and comfort Studies for the previous air permit application for the power plant (HI 90-04) did not identify any sensitive soils or vegetation in the vicinity of the plant. Therefore, since the maximum concentrations must be below the State Air Quality and Federal Secondary Air Quality Standards, the soils and vegetation would not be significantly impacted. 5. Mitigation Measures Construction and operation of the any future expansion of the Puna Generating Station's generating capaicity: would be approved only when state and federal regulatory authorities are satisfied that HELCO will be able to fully comply with the applicable rules, regulations, and air quality standards. Additional mitigation measures may be established by the Hawaii Department of Health (DoH) during the permitting process and may include limitations on the allowable size of the facility, emission control technology requirements, or specifications of fuel properties. The s projects design, including the stack height and emission controls, will be appropriate to minimize adverse air quality impacts. 6. References Hawaii State Department of Health.

HELLO is currently operating under a special use permit for their current activities and is seeking to rezone the site. HELLO wants to re-designate the site to the State's urban district, and rezone the site to the County's general industrial designation. HELLO wants to do this since the current use of the site is consistent with uses permitted under the general industrial designation. HELLO currently has no plans to either increase the generating capacity at the Puna Generating Station or increase the intensity of ancillary uses at the site. However, HELLO anticipates that the site's generating capacity and ancillary uses will be increased at some time in the future. No significant adverse impacts to fish and wildlife resources are expected to result from the proposed zoning change. However, the Service would like you to be aware that the Hawaiian hawk (Buteo solitarius) and Hawaiian hoary bat (Lasiurus cinereus semotus) have been sighted in the proximity of the generating station. The Service appreciates the opportunity to comment on the proposed zoning change. If you have questions regarding these comments, please contact Fish and Wildlife Biologist Elizabeth Sharpe by telephone at 808/541-3441 or by facsimile transmission at 808/541-3470.

No. P-7361 April 27, 1998 Mr. Al Lono Lyman Senior Project Manager CH2M HILL, Inc. 1585 Kapiolani Boulevard Suite 1420 Honolulu, Hawaii 96814 Dear Mr. Lyman: Subject: Request for Agency Comments Concerning Hawaii Electric Light Company's (HELLO) Puna Generating Station Land Use District Boundazy Amendment and Rezoning, TMK: 1-06-03: 93 (10.5 acres) We have received your letter dated March 25, 1998, requesting written comments from our agency regarding HELCO's proposed boundary amendment and rezoning for the Puna Generating Station. According to the information provided, the power generating activity was an ancillary use of a permitted sugar operation. When the sugar operations ceased, HELLO acquired a portion of the mill site and the adjoining railroad right-of-way in order to continue generating power. The Hawaii County Planning Commission approved HELCO's request for a Special Permit in 1988. The permit allowed HELLO to establish the electric power plant and the related improvements as the principal use of the site. In 1992, HELLO initiated service with its 20.8-MW CT-3 generating unit at the Puna Generating Station. HELLO is seeking to reclassify the 10.5-acre site from the Agricultural to the Urban District and to rezone the site from the A-20 agricultural zoning district to the County's general industrial district (MG). The Puna Generating Station site is less than one-half mile from Keaau Town, and one quarter of a mile from the closest point of the proposed Keaau Bypass Road. In 1993, three areas consisting of approximately 660 acres around the Keaau Town core were reclassified from the Agricultural District to the Urban District. Currently, the landowner, W.H. Shipman, Ltd. is developing a master plan for the 660 acres, and has begun discussions with a developer regarding residential development_ The surrounding land uses consist mainly of formerly cultivated sugar cane lands, vacant lands, small agricultural operations, and homes. Most of the surrounding properties aze lazge parcels of land which are also owned by W.H. Shipman, Ltd. With plans for schools, housing, and other urhan uses underway, HELCO's expectations that the site's generating capacity and ancillary uses will be increased at some time in the future are most likely correct. However, while the location of school facilities has been determined, the _ Mr. Al Lono Lyman Page 2 Apri127, 1998 location of other urban uses within the reclassified 660 acres have not been finalized. Further, some agricultural operations may be relocated, with W.H. Shipman offering land. ' Since HELCO currently has no plans to either increase the generation capacity at the Puna Generating Station or increase the intensity of ancillary uses, the applicant should explain the need for a boundary amendment from the Agricultural to the Urban District at this time. Acwrding to the information provided, i[ is our understanding that any expansion of the site's generating capacity or ancillary uses is allowed under the current Special Permit No. 686.

We have reviewed all of the correspondence you sent relating to historic sites on the subject property, including the Letter of September 21, 1988 from then Chairperson, William W. Paty. Because the area has been so extensively disturbed we believe that there are no significant historic sites remaining on the subject property. We thus believe that the proposed rezoning and boundary designation changes will have "no effect" on historic sites. If you should have any questions please contact Patrick McCoy (587-0006).

The Clean Air Branch, Department of Health has no comments on the proposed boundary amendment and rezoning, however, would like to offer the following clarifications on the air pollution control requirements: 1. The air permits are not "discretionary permits." Anew air permit or a permit amendment is required to be obtained prior to initiating construction on any plant modification that will result in an emission increase. This includes, as applicable, any increase in the generating capacity and ancillary uses at the generating station. 2. Any proposed plant modifications are required to comply with all state and federal air requirements including the national ambient air quality standards. 3 The Puna Generating Station is considered a major source of air emissions and subject to the covered source permit provisions. Depending on the level of emission increase from a proposed modification, there are different permitting actions, each incorporating different procedural and public participation requirements. The public participation requirements range from no public participation for a minor modification to a 30-day public comment period followed by a public hearing for a significant modification triggering the federal Prevention of Significant Deterioration (PSD) review. If you have any questions, please call Mr. Nolan Hirai of my staff at (808) 586-4200. Sinceerely, WIL~2ED K.

Permitted Use: Establishment of an Electric Power Plant and related improvements Tax Map Key• 1-6-3.93 Keaau Puna. Hawaii This is in response to your letter dated January 2, 1997, relating to the above-referenced Special Permit No. 686. We have reviewed our files and hereby confirm that the HELCO's Puna Generating Station situated on the subject site is located within the area designated as "Industrial" by the General Plan Land Use Pattern Guide (LUPAG) Map. Further, Special Permit No. 686 does not impose any conditions limiting the generating capacity of the power plant nor the construction of related improvements. According to the hearing transcript of the November 15, 1988, Planning Commission hearing, a representative from HELCO indicated that the existing plant then needed to be more efficient and possibly increase the number of megawatts. Therefore, we affirm that the Special Permit does allow HELCO to expand its electric power plant and related improvements on the subject property. Mr. AI Lono Lyman Page 2 February 3, 1997 Subsequent to the approval of Special Permit No. 686, plan approvals were granted by the Planning Director and building permits were issued by the Department of Public Works Building Division for the combustion turbine #3 control house, combustion turbine #3 six steel tanks, a 250-foot stack, storage building and other improvements. Please be advised that should there be any additional improvements to the generating station site, plan approvals must be secured from this department as well as approvals from other affected government agencies.

The property is located approximately one mile east of the Keaau Town Center at the end of Milo Street in the vicinity of the former Puna Sugaz Company Mill site, Keaau, Puna, Hawaii, TMK: 1-6-3:93. GENERAL INFORMATION 1. Permission to Use Roads: The subject property is bound by private easement roads along the north and south property boundaries. The entrance road to the Puna Generating Station is referred to as Keaau Road (TMK: 1-6-3: Portion of 73); with an additional easement, TMK: 1-6-03: Portion of 15, that loops azound the subject property. Permission to use these private roads is through a Grant of Easement from W.H. Shipman, Ltd. and was recorded at the Bureau of Conveyances at January 24, 1992. 2. Special Permit No. 686: Effective November 22, 1988, the Planning Commission approved the request by Hawaii Electric Light Company (HELLO) to establish an electric power plant and related improvements. A power plant was originally run by Puna Sugar Company until its closing in 1984. (See Exhibit A -Special Permit No. 686) APPLICANT'S REQUEST 3. Request: The applicant is requesting that subject property be redesignated from State Land Use Agricultural to Urban district and rezoned from A-20a to MG-10a. Although a Special Permit was originally issued for the current operations, the applicant is requesting to legitimize the uses and bring the parcel into conformance with ~}TfAc N : C- y33 CO%1/S 8S *.;t~ AC. permitted uses within the Urban district. The parcel is the site of the Puna Generating Station. 4. Plans/Capacity of Plant: Currently, the power plant includes a 15.5 MV steam unit acquired from AMFAC and a 20.8 MW combustion turbine generator (CT-3). HELCO plans to continue using the site to generate electricity and related ancillary _ improvements. There are no plans to expand the generation capacity through the yeaz 2017. However, the generating capacity at the site may be increased after the year 2017. Related improvements include fuel storage, water pumps and storage, a switchyard and transmission lines and related facilities. The only immediate changes are to place the 15.5 MV steam generation unit on a cold standby status in 1999 and return the steam unit to active status in the year 2003. 5. Employees: There are three shifts with two employees per shift. Other HELCO staff visits the site for specific tasks; and occasionally contractors are at work on the site. There is a security fence with a locked security entry gate. 6. Driveway/Parking: The site has paved and graveled areas for parking. The driveway leading to the facilities is paved. 7. Access: Primary access to the Puna Generating Station is from Highway 11 onto the Old Volcano Road and to Keaau Road (TMK: 1-6-03: Portion of 73) and TMK: 1-6-03: Portion of 15. Both roads ar private easements are graveled and owned by W.H. Shipman, Ltd. According to the applicant's report, the Keaau By-Pass Road, currently under construction, will intersect with Keaau Road. For traffic turning onto the Keaau Road from the By-Pass Road, there will be deceleration lanes and turning pockets with a stop sign for left turns onto Keaau Road. From the Keaau Road onto the By-pass Road, a stop sign will be located on Keaau Road and acceleration lanes constructed on the new highway. According to a handout, dated November 18, 1998 by the Departtnent of Transportation, Highways Division, Hawaii District, the Keaau By-Pass Road will begin at the Old Keaau Road and end neaz the Humane Society. Completion is estimated for mid-July 1999. The Old Volcano Road/Keaau By-Pass Road (presently Keaau Road) intersection, is proposed to be reconstructed. -2- 8. Diesel Delivery Trips: Diesel fuel delivery is approximately 21 to 49 trips per week. 9. Traffic: A Traffic Assessment was prepared by Austin, Tsutsumi & Associates, Inc. (letter dated May 11, 1998). The report concluded that no improvements are necessary at the intersection of Mamalahoa Highway and Keaau Road. It was observed that during PM peak period, a relatively high number of vehicles on Mamalahoa Highway _ turn onto Keaau Road and right onto Old Volcano Road. Based on existing traffic count data, the number of vehicles utilizing the Keaau Road for the HELCO facility area is relatively low. During the PM peak period, a relatively high number of vehicles (267) on Mamalahoa Highway turn left onto Keaau Road and right onto the Old Volcano road. However, the number of vehicles utilizing the section of Keaau Road that services the HELCO facility is relatively low. During the AM peak hour, 46 vehicles per hour (vph) were observed. During the PM peak hour, 33 vph use Keaau Road. Although, left-turn movements from Mamalahoa Highway to Keaau Road is operating at LOS F, according to the report, these long delays are due to the northbound opposing vehicles on the highway and only a small number of vehicles are affected. The report the recommended no improvements for the Mamalahoa Highway and Keaau Road. ('T'raffic Assessment attached to Application as Appendix B) 10. Air Quality Impacts: A document, "Puna Generating Station, Air Quality Impacts", was prepared by Jim Clary and Associates, dated June 1998. The study summarizes existing applicable regulations and standards that the Puna Power Plant is required to comply with. Existing air quality is monitored by a station located approximately 1.8 km southwest of the plant. Data collected confirms that the plant does not cause an exceedance of the State Ambient Air Quality Standards (SAAQS) or the National Ambient Air Quality Standards (NAAQS). Any future expansion of the facilities would be approved when HELCO complies with applicable rules, regulations and air quality standards of state and federal agencies. (Air Quality Study attached to Application as Appendix C) 11. Noise: According to the applicant, personnel measured background noise levels at the site and measurements indicate that the station is in compliance with the State DOH -3- 70dBA standard at the property lines. The applicants shall comply with applicable noise regulations in accordance with the Department of Health. 12. Additional Information: The applicant has submitted a State Land Use Boundary Amendment and Change of Zone Application with Environmental Report in support of the request. (See Exhibit B -Hawaii County Environmental Report with _ Applications) STATE AND COUNTY PLANS 13. SLU: Agricultural. 14. State Plan: The proposed Urban District and industrial development would be consistent with the goals, objectives and policies for the economy. 15. General Plan: The proposed development would be consistent with the Economic, Land Use and Industrial goals, policies, standards and courses of action of the General Plan. 16. General Plan LUPAG MAP: Industrial Area. Since 1971, the area of the old Puna Sugar Mill has been designated as Industrial Area. During the 1989 General Plan Comprehensive Review, the Industrial Area designation was expanded by redesignating lands in the vicinity from Intensive Agricultural and Orchards to Industrial. This area was considered for industrial expansion as a variety of industrial uses have been established in the vicinity through the Special Permit process. The County had determined that the industrial designation would promote and encourage additional utilization of this area. Also, in 1989, it was observed that traffic patterns already indicated tremendous movement across the Puna -South Hilo District boundary. Keaau is in close proximity to the City of Hilo and has an excellent transportation link via the Volcano Highway-Kanoelehua Avenue. In addition, Keaau provides a natural focal point provided by the highway system that could result in the concentration of additional goods and services at Keaau. To facilitate this growth, also during the 1989 review, the lands on the eastern side of the existing Keaau urban area were redesignated from Orchards and Urban Expansion to Low Density Urban. Likewise, the lands to the west and southwest side of Keaau Town were redesignated from -4- Orchards to Urban Expansion. Areas further to the east of the subject property are designated Intensive Agricultural and other surrounding areas aze Orchards. Lands to the west are designated Low Density Urban. (See Exhibit C -General Plan Map For Keaau Area) 17. Zoning: Agricultural - 20 acres (A-20a). The subject request would legitimize the _ Puna Generating Station as a permitted use within the Industrial zoned district (MG-10), which the subject request is for. 18. SMA: The subject property is not situated with the Special Management Area boundary. DESCRIPTION OF PROPERTY AND SURROUNDING AREAS 19. Subject Property: The subject property is approximately 10.5 acres in size and is the site of an existing power plant. It is triangular-shaped and relatively level. The property was previously a portion of TMK: 1-6-03:05, and subsequently subdivided out in 1989 (Subdivision 5827). TMK: 1-6-03:SS,located within the subject property and which is the site of a County of Hawaii Chlorinator Pump, is not a part of this request. It will remain A-20a. 20. ALISH: The subject property is "not classified" according to the ALISH Map. 21. FIRM: Zone "X" or outside the 500-year flood plain. 22. U.S.D.A. Soil Type: Olaa Silty Clay Loam (OaC), which consists of dazk brown extremely stony silty clay loam about 16 inches thick with a dazk-brown subsoil that is extremely stony silty clay loam about 9 inches thick and underlain by Aa lava. This soil has a medium acid surface layer and a slightly acid subsoil. Permeability is rapid, runoff is slow and the erosion hazard is slight. This soil is mainly used for sugarcane. 23. Land Study Bureau Soil Rating: Urban. 24. Drainage: Standard drainage improvements would be developed in accordance with requirements of the Department of Public Works. 25. Floral/Faunal and Archaeological Resources: Although no floral and faunal surveys were conducted, the site has been cleared and operated as the Puna Sugaz Mill site. -5- Due to the quasi-urban setting of the subject and immediate area, impacts to endangered faunal species should be negligible. Similarly, it is highly unlikely that any archaeological remains would be present on the site. 26. Surrounding Zoning and Land Uses: Properties immediately surrounding the subject parcel are similarly zoned A-20a. Surrounding properties consist mainly of formerly cultivated sugar cane lands, vacant lands, small agricultural operations and residences. To the east of the subject property is the existing AMFAC Tropical Products tropical fruit packing and papaya puree processing facilities. Adjacent and southwest of the subject property is the McCully property, TMK: 1-6-03:5, which recently secured a State Land Use Boundary Amendment from Agricultural to Urban and a Change of Zone from A-20a to FA-3a (Ordinance 97-67) and MCX-20 (Ordinance 98-61). The FA-3a portion of TMK: 1-6-03:5 abuts the Puna Generating Station. Also, to the south along Milo Street is the site of Greenhouse Specialists (SPP-931) and the existing Pacific Floral Exchange business. Adjacent and to the east of Pacific Floral Exchange is the proposed school site for Hawaii Christian Camping Association (SPP 925). It should be pointed out, that when the special permit for the school and church was approved, the Hawaii Christian Camping Association was aware of the Puna Generating Station. They expressed no objections to being located in the same vicinity. A condition was included in SPP 925 that the school relocate should the health and safety of the school/church be a concern. Lands to the southwest of the subject property along the first 1,800± section of Milo Street, are lots approximately 13,000 square feet in size which are zoned RS-10. Existing uses along Milo Street are mainly single-family residential in nature. A few RS-15 zoned properties are also located in the area. Along the intersection of Milo Street and the old Volcano Road are properties zoned CV-10. Approximately 800 feet to the south at the Keaau-Pahoa/Old Volcano Road intersection is the Keaau Town Center. 27. LUC Docket No. BR93-699 (LUC No. 884): In July 1994, the State Land Use Commission approved a petition filed by the Office of State Planning for a boundary amendment from Agricultural to Urban District for approximately 660 acres of land -6- owned by W.H. Shipman, Ltd. The newly designated Urban lands, located within the vicinity of the subject property, would accommodate W.H. Shipman's master plan for Keaau and include a mix of commercial, industrial, residential, parks and open space and public facilities. (See Exhibit D) 28. Existing Industrial Zoned Lands: Existing industrial zoned lands in the Puna District _ are located off Highway 11 at the Shipman Industrial Pazk, approximately .7 miles from the subject property. The County Council approved the General Industrial (MG-20) zone district effective August 19, 1986, for approximately 488± acres of land for the development of Shipman Industrial Park. A portion of the Shipman Industrial Park has been subdivided in increments between 1987 - 1991. There are presently a total of 88 lots with average lot size ranging from one half acre to 3 acres. Existing uses in the area include: heavy equipment construction baseyards, building supplies baseyard, paving construction baseyards, distributor wazehousing, supetmazket warehousing, industriallmanufacturing baseyards and other uses. Allied Aggregates leases one of the larger lots for its existing quarrying operation. For the East Hawaii area, industrial zoned lands and activities are primarily located in the City of Hilo at the Hilo harbor, airport and Kanoelehua Industrial areas. Industrial expansion since 1970 has largely occurred through the expansion and in-filling of these areas. PUBLIC SERVICES AND FACILITIES 29. Access: Legal access to the subject property is from the Old Volcano Road, a County maintained road, which has a 50-foot right-of--way onto Keaau Road (TMK: 1-6-03:Portion of 73) and TMK: 1-6-03: Portion of 15, which are graveled roadway easements owned by W.H. Shipman, Ltd. These roads were previously used as cane haul roads for Puna Sugar Company. The applicant has easement rights over these roadway lots for access to the subject parcel. It should be noted that the Keaau By-Pass Road is presently being worked on and is proposed to be located within the vicinity of Keaau Road. 30. Water: There are three HELCO wells on the subject site of which approximately 12.1 million gallons per day (mdg) are used. Groundwater is used for cooling water pumps, -7- cool fans, generators, the existing combustion turbine, compressors, pumps, air heater wash, various fire hoses on each floor and for wash-down and cooling needs. Water is also provided to the adjacent papaya operation. The papaya operation also uses water provided through a meter located on the subject site. During periods when the steam plant is not in operation or when the deep wells are shut down, the papaya operation _ provides HELCO with county water for its needs. The Puna Generating Station is located over the Keaau Aquifer System. Wells on site have not displayed salinity of more than 10 parts per million. Current draw from the Keaau Aquifer is less than 20 mgd, with capacity of existing wells in the aquifer totalling 27 mgd. 31. Wastewater: There aze four existing wastewater generated by the power plant. Non- contact condenser cooling water, is dischazged from the condenser into a reinjection well located off-site, and is permitted by underground injection control (UIC) permit No. UH 1438. Auxiliary cooling water is disposed of into aditch/culvert and discharged off-site. Sanitary wastewater cesspool discharge comprises of approximately 30 gallons per hour. Industrial wastewater discharge receives primary treatment on site and is trucked to the Hill Generating Station in Hilo, where it is further treated and discharged into the facility's injection wells. HELCO is considering a plan to isolate and recycle all flows out of the existing cooling water pumps through a service water cooler. There is no municipal wastewater system in the area. A cesspool or a septic system meeting with the requirements of the Department of Health will be installed by respective lot owners. According to the Department of Health, a portion of the subject property is located within 1,000 feet of a drinking water well. 32. Solid and Hazardous Wastes: Solid waste generated by HELCO is recycled to the extent practicable, with the remainder being disposed of at the County landfill. Hazardous waste is disposed of in accordance with federal and state regulatory requirements. 33. Other Utilities/Services: Electricity and telephone are available to the subject property. Police, fire protection and emergency medical services aze located in the village of Keaau, less than one mile from the subject property. -s- 34. Environmental Assessment and Analysis: A. Relationship between Local Short Term Uses of the Environment and Maintenance and Enhancement of Long Term Productivity: No short-term changes are anticipated by the applicant that will impact the components of the environment. Beyond the year 2017, the Puna Generating Station's generating _ capacity may be expanded. One impact with possible future expansion is the change in visual environment. Secondary impacts are related to air emissions. B. Mitigate Measure Proposed to Avoid, Minimize, Rectify or Reduce Impact: According to the applicant, there are no mitigative measures planned or proposed as no development is currently planned. C. Alternatives to the Proposed Development: According to the applicant, there are no alternatives since no development is proposed. From a planning perspective, the Puna Generating Station could continue operation under the Special Permit. D. Irreversible and Irretrievable Commitments of Natural Resources Involved if Proposed Action is Implemented: The Puna Generating Station has been in active use for over a decade and for sugar milling prior to that. No new development is currently being planned. The continued use of diesel fuel, rather than other sources is based on economics. AGENCIES' COMMENTS 35.

Sox 1027 ?'ilo, ?Iawaii 90720 Dear "1r. Oss: Special Use Permit Application TMK: 1-6-03: Por, of 5 The Planning Commission at its duly held public bearing on November 15, 1981;, voted to approve your application, Special Gse Permit No, u'aG, to allow the esr_ahlishment of an electric poker rlar.t ar:d relater improvements on. 9.3 acres of land situatd ::itc~n t}-.~ estate Land Use Agricultural District at Keaau, Pura, 3avaii. ?,nrroval cf this request is based on the following: The granting of this request would promote the effec*_iveness and o',-.jectives of Chapter 205, Hawaii Revisew Statutes, as amended. The State Land Use Law and Regulations are intended to nreserve, protect, and encourage the development of lands in the State for those uses to which they aze best auite~ in the interest of the public health and welfare of the people of the State of Hawaii. In the case of agricultural districY.s, rife intent is to nreserve or keep lands of high agricultural potential in agricultural use. While the subject area has bean classified "Prime' by the ALISH asap system, tY,e land has been improved with the sugar mill operations and the esistinq power plant. This approval should nut affect the agricultural resources of this parcel, since sugar is no longer a viable agricultural pror3uct in this area. Furthermore, a facility for anthurium racking and processing and a papaya ~:et~:^dration were given special perr.;its by the Manning Ccr:miGSion erithin 1,000 feet cf the power plant. Uecause of the curr~•nt industrial pressures occurring in the vicinit}• of the EXHIBIT N~, , 2 1933 r Mr. Norman Oss, President Hawaii Electric Light Company, Inc. November 22, 1988 Page 2 proposed site coupled with the non-productive state of the land, approval of this request would not adversely affect the potential productivity of the area. _ The desired use will not adversely affect the surrounding properties. As stated previously, the subject parcel is largely surrounded by vacant land. Since the power plant and sugar mill have been in existence over a period of time, the impacts to nearby residences would not be an introduction of anything new to the area. Access will be gained along a private roadhay system which runs through abandoned cane lands. This is not anticipated to generated new adverse impacts. The desired use will not unreasonably burden public agencies to provide roads and streets, sewers, water, drainage, school improvements, police and fire protection. Responding agencies raised no objections to the existing use. The use will not substantially alter or change the essential character of the land and the present use. As previously mentioned, the character of the area is a mix of industrial-type uses intersperse6 with vacant sugar land and nearby residential uses. The continuation of the power plant operation will not significantly change the environment. Unusual conditions, trends, and needs have arisen since the district boundaries and regulations were established. The slow decline and eventual shutdown of a major industry have led to an unusual condition in Reaau where a power plant stands independent of former agricultural support systems. Nevertheless, HELCO's need to supply the current demand can be met with the 14 megawatt plant. The request is not contrary to the General Plan. In fact, the Land Use Pattern Allocation Guide (LUPAG) Map designates ttie property for Industrial uses. Based on the above considerations, it is determined that the establishment of an electric power plant is an unusual and reasonable use of land, which would not be contrary to the objectives sought to be accomplished by the Land Use Law Rules and Regulations. Approval of this request is subject to the following conditions: t9r. ;7orman Oss, President Hawaii Electric Light Company, Inc. *lovemher 22, 1988 Paa~ 3 1.

SUB.TECT ItEOUEST 1. Details of Proposal a. Subject Request and Property Description _ The applicant, Hawaii Electric Light Company, Inc. (HELLO), is the owner of the site containing the Puna Generating Station. HELLO is requesting: • State Land Use boundary amendment from the Agriculture to Urban District (pursuant to Hawaii Revised Statute (HRS) Section 205-3.1, as amended, and Chapter 28 of the Hawaii County Code), and • County rezoning from Agricultural (A-20a) to MG-10a. HELCO's Puna Generating Station is identified as Tax Map Key (TMK) 1-6-03:93. The HELLO site is comprised of a portion of the former Puna Sugaz mill property and a portion of a former railroad right-of-way. The HELLO site is located in the Puna District, County of Hawaii. Figure One depicts the location of [he site. Figure Two is a site plan of the Puna Generating Station, depicting all existing uses and structures. Figure Two does not reflect any new structures, as there are none that are currently planned. Appendix A is a metes and bounds description of the subject property. Power generation was originally undertaken in conjunction with the operation of the sugar mill that previously occupied the site. Electricity was generated for both the sugar operations and employee-residents. Until the sugar mill ceased operations in the early-1980s, the power generation activity was an ancillary use of a permitted agricultural activity. After the sugaz operations ceased, HELLO acquired a portion of the mill site to continue generating power. In late 1988, the Hawaii County Planning Commission approved HELCO's request for a Special Permit for the site. Special Permit No. 686 allowed HELLO to establish the electric power plant and related improvements as the principal use of the site. The Special Permit was required, since the power generation use was no longer an ancillary use to a permitted agricultural activity. The Special Permit does not impose any conditions limiting the generation capacity or the mix of related improvements on the site. In 1992, HELLO initiated service of a 20.8-MW combustion turbine unit-three (CT- 3) generation unit at the Puna Generating Station.

Statement of Objectives and Reason for the Request HELCO wants to rezone the site from an agricultural zoning designation to the County's general industrial designation. The general industrial zoning designation is consistent with the current use of the site and the County's General Plan "Industrial" designation for the site and surrounding area. _ By a letter dated February 3, 1997, the County Planning Director confirmed that the HELCO Puna Generating Station site is within the area designated as "Industrial" by the General Plan Land Use Pattern Guide (LUPAG) Map. The letter also confirmed that Special Permit No. 686 does not impose any conditions limiting the expansion of the site's generation capacity and related improvements. (Letter dated February 3, 1997, from Ms. V. K. Goldstein, Planning Director, Hawaii County.) HELCO's request for both an amendment of the State Land Use Boundary to the Urban District, and the request for an amendment of the County's zoning designation to general industrial conforms with the County General Plan LUPAG map designation for the site and applicable sections of the General Plan. c. Number of Acres TMK 1-6-03:93 has an area of 10.5 acres, and is comprised of the 9.3-acre former mill site and a 1.2-acre area that was part of a railroad right-of-way. d. Proposed Use (units/lots/floor area) HELCO plans to continue using the site to generate electricity and for related ancillary improvements. These are currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988. Generation Capacity The Puna Power Plant site currently includes a 15.5 MW steam unit acquired from AMFAC and a 20.8 MW combustion turbine generator (CT-3). HELCO's most current resource plan for power-generation needs are attached as Table One.

Also upon Encogen phase 2 installation, HELCO plans to place the Puna steam unit on cold standby with no ca aci valve. The Puna Steam unit is scheduled to return to service in 2003 to defer the need for ST-7. Source: "Hawaii Electric Light Company, Ltd. 1996 Electric Utility System Cost Data Filling," prepared by Hawaiian Electric Company, Inc., June 30,1998. (6) Generating Station site. The only changes currently anticipated at the Puna Station is placing the 15.5 MW steam generation unit on a cold standby status in 1999, and returning the steam unit to active status in the yeaz 2003. While HELCO's current resource plan does not reflect increasing the generation capacity at the Puna Generating Station through the yeaz 2017, the generation capacity at the site may be increased sometime in the future after the year 2017. Further, changes in the assumptions used to prepare the resource plan could lead also to changes in the generation capacity needed by HELLO at the Puna site prior to the year _ 2017. Related Improvements Related improvements include non-generating and ancillary uses at HELCO's Puna Generating Station. These include fuel storage, water pumps and storage, a switchyazd, and transmission lines and related facilities. HELLO currently has no plans to add any related improvements at the Puna Generating Station. However, these may be increased at some yet unspecified time in the future. e. Time Frame and Cost Since HELLO currently has no plans to increase the generation capacity or to expand the related improvements at the Puna Generating Station, the time frame and cost are not relevant. f. Employees and Others Using Site HELCO's current full- and part-time staffing for the Puna Generating Station consists of three shifts with two employees per shift. Other HELLO staff visits the site, as required by specific tasks. HELLO also occasionally has contractors working at the site for specific tasks. County Water Department staff occasionally service the department's facilities located within the HELLO site. There are not any Water Department personnel assigned to the site on a full- or part-time basis. The site has a security fence and a locked security entry gate. The fence and gate are to preclude unauthorized personnel and vehicles from entering the site. The fence generally follows the site's property line, although along Keaau Road the fence is set back from the property line. (7) g. Pazking Arrangements The site has on-site paved and graveled areas within the fenced portion of the site to meet the pazking requirements of the County zoning code. No off-site pazking is required or contemplated. h. Traffic Impacts Existing Conditions - The primary access to the Puna Generating Station site is from Mamalahoa Highway via Keaau Road. Mamalahoa Highway (State Route 11, elsewhere referred to as Routes 19 and 190, and also known as Hawaii Belt Road) is a major arterial serving most of the Island of Hawaii. Within the vicinity of the HELLO site, Mamalahoa Highway is afour-lane highway that runs generally in the north-south direction. Keaau Road is a private road providing access from Old Volcano Road to the existing HELLO Generating Station. The two-lane Old Volcano Road runs parallel and east of Mamalahoa Highway. Keaau Road crosses Old Volcano Road. The current staffing of the generating station consists of three shifts with two employees per shift. Diesel fuel deliver currently is comprised of 21 to 49 trips per week. Weekday morning (AM) and afternoon (PM) period traffic counts were conducted by Austin, Tsutsumi & Associates, Inc. (ATA) at two intersections in the morning and evening peak period on March 19 and 20, 1997. Appendix B is the ATA report of the traffic analysis titled "HELCO's Puna Generation Facility Traffic Assessment." The two intersections analyzed in the report aze Keaau Road and Mamalahoa Highway, and Keaau Road and Old Volcano Road. The following summarizes the report's findings: • During the morning AM peak period, the peak direction of traffic flow on Mamalahoa Highway is in the northbound direction with approximately 2,640 vehicles during the peak hour and approximately 640 peak hour vehicles in the southbound direction. During the afternoon PM peak period, the peak direction of flow is in the opposite direction with approximately 1,800 peak hour vehicles in the southbound direction and approximately 770 peak hour vehicles in the northbound direction. • It was observed that during the PM peak period, a relatively high number of southbound vehicles (267 vehicles per hour (vph)) on Mamalahoa Highway turn left onto Keaau Road and then turn right onto Old Volcano Road. It is assumed that most of these motorists aze bound for the residential areas of Keaau Town. • Based on the existing traffic count data, the number of vehicles that utilizes Keaau Road serving the HELLO facility area is relatively low. During the AM peak (8) hour, only 46 vph with 12 vph in the westbound and 34 in eastbound direction were observed. During the PM peak hour, only 33 vph utilize Keaau Road with 27 in the westbound direction and 6 in the eastbound directions. • Level of Service (LOS) is a qualitative measure used to describe the conditions of traffic flow, ranging from free-flow conditions at LOS "A" to congested conditions at LOS "F." The methods utilized in the ATA traffic analysis for calculating delays and corresponding levels of service at stop-controlled intersections are based on the 1994 Hi~hwav Capacity Manual -Special Reaon _ 209. • The ATA traffic analysis indicates that during the AM peak hour, the southbound left-turn from Mamalahoa Highway to Keaau Road is operating at LOS F. Long delays to this particular movement are mainly due [o the number of northbound opposing vehicles on Mamalahoa Highway. The westbound left-tum from Keaau Road to Mamalahoa Highway is also operating at LOS F during the AM peak hour, but this only affects a small number of vehicles (only one vehicle during the peak hour was observed). The remaining movements at both intersections are operating at acceptable levels of services (LOS A, B, C or D). • Based on existing traffic volumes plus expected ambient growth in traffic caused by regional growth throughout the Island of Hawaii, traffic growth is anticipated to be 1% per year. In the year 2001, the peak hour operations at both intersections are expected to be similar to existing 1997 operating conditions. • ATA recommends that no improvements are necessary at the intersections of Mamalahoa Highway and Keaau Road. Although the westbound left-turn is currently operating at an undesirable level of service, only a small number of vehicles are affected. And although the southbound left-turn from Mamalahoa to Keaau Road is operating at an undesirable level of service, this only occurs during the morning peak period when the opposing northbound approach is heavy. Based on the traffic counts conducted by ATA, most of these vehicles are bound for Keaau Town, which can also be accessed by Ahoa Street and Kalapana Road further south. Keaau Bypass Road The State Department of Transportation, Highways Division, is currently constructing the first phase of a two-phase project comprised of a four-lane bypass road routing Keaau-Pahoa (State Highway 130) traffic around the Keaau Town. An environmental assessment (EA) was prepared for the project's proposals, and a "Notice of Determination Negative Declaration" was completed and accepted in December 1995 for the Keaau-Pahoa bypass road, State Department of Transportation, Highways Division Project No. 130-B-01-92. (9) The alternative selected for the 2.2-mile project will begin on the Keaau-Pahoa Road, in the vicinity of the fotmer plantation manager's house (now referred to as Banyan Inn) proceed between 8-1/2 Mile Camp and the Milo Street neighborhood, and return to Route 11 (Mamalahoa Highway) at Keaau Road. A traffic analysis for the Keaau-Pahoa Road EA was prepared by Barton-Aschman Associates, Inc., and is dated December 1993. The traffic report indicates that if the bypass road were not built, significant improvements would have been required on Route 11 (Mamalahoa Highway). The Keaau-Pahoa Road EA traffic analysis also _ indicates that construction of the bypass road will favorably impact the road intersections serving the HELCO Puna Generating Station and improve the LOS at the intersection of Keaau Road and Route 11 (Mamalahoa Highway). Telephone conversations with a representative (personal conversations with Robert Taira, Design Engineer, May 6 and 8, 1998) of the State Department of Transportation, Highways Division, indicates that the bypass road intersection at Route 11 (Mamalahoa Highway) will be fully signalized with right- and left-turn lanes and acceleration and deceleration lanes. For traffic fuming onto Keaau Road from the bypass road, there will be deceleration lanes and turning pockets with a stop sign for left turns on to Keaau Road. For traffic turning from Keaau Road onto the bypass road, a stop sign will be located on Keaau Road and acceleration lanes will be constructed on the new highway. i. Other Related Information There is no other related information. j. Proposed On-site and Off-site Infrastructure There is no on- or off-site infrastructure that would be impacted. B. CONFORMANCE WITH STATE/COUNTY PLANS AND LAND USE DESIGNATIONS 2. Hawaii State Plan HELCO's proposed reclassification of the Puna Generating station site conforms to the applicable goals, objectives, and policies of the Hawaii State Plan. The Hawaii State Plan, Chapter 226, "Hawaii Revised Statutes," is a guide for future long-range development. It identifies the goals, objectives, policies, and priorities for the State; allocates limited resources; improves coordination among federal, state, and county agencies; and establishes a system for integrating all major state and county activities. Section 226-14 of the State Plan, Objectives and Policies for Facility Systems applies, in general, to the proposed project and states the following: (10) a. Planning for the State's facility systems in general shall be directed towards achievement of the objective of water, transportation, waste disposal, and energy and telecommunication systems that support statewide social, economic, and physical objectives. b. To achieve the general facility system objective, it shall be the policy of this State to: 1. Accommodate the needs of Hawaii's people through coordination of facility systems and capital improvement priorities in consonance with - state and county plans 2. Encourage flexibility in the design and development of facility systems to promote prudent use of resources and accommodate changing public demands and priorities 3. Ensure that required facility systems can be supported within resource capacities and at reasonable cost to the user 4. Pursue alternative methods of financing programs and projects and cost-saving techniques in the planning, construction, and maintenance of facility systems. The HELCO Puna Generating Station will contribute to meeting the demand for electricity on the Island of Hawaii and to maintaining and improving system reliability. Section 226-18 of the Hawaii State Plan, "Objectives and Policies for Facility Systems Energy/Telecommunications," applies specifically to the project and states the following: a. Planning for the State's facility systems with regard to energy shall be directed towards the achievement of the following objectives: 1. Dependable, effecient, and economical statewide energy systems capable of supporting the needs of the people 2. Increased energy self-sufficiency where the ratio of indigenous to imported energy use is increased; and 3. Greater energy security in the face of threats to Hawaii's energy supplies and systems. b. To achieve the energy objectives, it shall be the policy of this State to ensure the provision of adequate, reasonably priced, and dependable power and telecommunication services to accommodate demand. c. To further achieve the energy objectives, it shall be the policy of this State to: 1. Support research and development as well as promote the use of renewable energy sources; 2. Ensure that the combination of energy supplies and energy-saving systems are sufficient to support the demands of growth; (11) 3. Base decisions of least-cost supply-side and demand-side energy resource options on a comparison of their total costs and benefits when a least-cost is determined by a reasonably comprehensive, quantitative, and qualitative accounting of their long-term, direct and indirect economic, environmental, social, cultural, and public health costs and benefits; 4. Promote all cost-effective conservation of power and fuel supplies through measures including: _ A. Development of cost-effective demand-side management programs; B. Education; and C. Adoption ofenergy-efficient practices and technologies; 5. Ensure to the extent that new supply-side resources are needed, the development or expansion of energy systems utilizes the least-cost energy supply option and maximizes efficient technologies; 6. Support research, development, and demonstration of energy efficiency, load management, and other demand-side management programs, practices, and technologies; and 7. Promote alternative fuels and energy efficiency by encouraging diversification of transportation modes and infrastructure. The Puna Generating Station, in the context of HELCO's integrated approach to energy production and conservation, conforms to these objectives and policies. At this time, alternative fuels and technologies do not represent the least-cost energy supply option or the maximum efficient technology. HELCO is also actively participating in education and research programs to further develop alternative fuels and technologies in Hawaii. 3. State Energy Functional Plan HELCO's proposed reclassification of the Puna Generating station site conforms to the applicable priority guidelines of the Hawaii State Plan and the adopted functional plans. The Hawaii State Plan requires the development of State Functional Plans (SFPs). While the Hawaii State Plan establishes long-term objectives for Hawaii, the SFPs delineate the specific strategies and prioritize actions that need to be addressed in the short term. The objectives of the State Energy Functional Plan (1991) are to achieve dependable, efficient, and economical statewide energy systems capable of supporting the needs of the people and to increase energy self-sufficiency. The major issues identified in the Plan that apply to the Puna Generating Station are discussed below. The Puna Generating Station meets the objectives related to energy conservation, energy efficiency, and alternative and renewable energy; however, it does not address the objective of furthering energy self-sufficiency. (12) Energy conservation and efficiency can reduce the dependence on imported fossil fuels and overall energy demand. To achieve this, an Integrated Resource Plan (IRP) was developed and approved by the Public Utility Commission (PUC). Integrated Resource Planning is the process of developing, implementing, monitoring, and evaluating a utility resource plan that identifies an optimum mix of energy resources for meeting forecasted levels of consumer energy needs. Demand-Side Management (DSM) programs, which are a component of the IRP, were designed to influence customer consumption of electricity in a manner that will produce changes in the utility's demand. Potential programs include conservation, energy efficiency, load management, and fuel - substitution. The energy conservation and efficiency policy and action items pertaining to the Puna Generating Station are as follows: Policy A(I Promote and Stimulate Greater Energy Efficiency and Conservation in Non-Transportation Sectors Action A(I)(a): Provide Technical Support and Assistance to the State Government, County Governments, the PUC, and The Energy Utilities in Developing the Integrated Resource Planning (IRP) Process and Carrying Out Demand-Side Management (DSM) Assessments. Action A(I)(b): Advance the Use of Demand-Side Management (DSM) by Creating Pilot Programs and Promoting Education of Local Energy Producers and Users. Through the IRP process, HELCO has developed along-range energy plan for Hawaii County. The IRP developed energy plan considers both the traditional supply-side resources and the customer (demand-side) resources that are available. IItP has brought about changes in the way utilities conduct their business, by including demand-side options as a resource and by having the public participate in the planning process through advisory groups. HELCO formed an advisory group representing business, government, environmental, cultural, and community groups. Those groups with a special interest in energy issues, as well as individuals who could lend special expertise to the process, were included. The advisory group met several times during the plan development process. The meetings covered such areas as organizational issues, forecasting, demand-side resources, supply-side resources, and the IRP objectives and principles. Public meetings were also held to present the forecasted sales and peak demand, identify DSM and supply-side resource options, and to obtain feedback into the IItP process. These public meetings were also intended to introduce the IRP process to the general public so that they may have a better understanding of the participatory process. The IItP programs provide peak-demand saving. However, because energy efficiency and peak capacity reductions have not been comprehensively pursued by any organization in Hawaii to date, there is considerable uncertainty about how to structure the DSM programs. Monitoring of the implementation process will be important, and programs will need to be adjusted as the implementation process moves forward. HELCO expects (13) to update its DSM program plans annually to optimize program implementation and energy savings. The State is encouraging development of alternative and renewable energy sources as Hawaii's primary energy source. These resources include geothermal, ocean thermal (OTEC), solar photovoltaic, biomass, wind, and hydropower. Although the State has made progress in alternative energy technologies, only geothermal currently provides a potential for firm, reliable electricity. It is the only commercially mature indigenous resource available in large quantities that can be converted to baseload (24-hour-per-day) _ electricity. Other alternative energy resources, such as solaz and wind technologies, do not provide firm, baseload power and are not economically feasible at this time. HELCO has contributed to and constructed facilities for alternative and renewable energy resources, such as wind and hydroelectric power. HELCO also provides rebates to commercial users who install solar power units. HELCO also has power purchase contracts with independent power producers. These power purchase contracts are based on alternative and renewable technologies. Examples include sugaz cane bagasse and coal-fueled steam turbine generators. While extensive dependence on such contracts can increase supply risks, HELCO has evaluated and continues to evaluate IPP alternatives and renewable energy power supply offers. 4. Applicable Goals/Policies and Objectives of the Hawaii County General Plan A County Ordinance with an effective date of November 14, 1989, amended the Hawaii County General Plan. The General Plan has goals, policies and standards for 13 topics: economic, environmental quality, flood control and drainage, historic sites, natural beauty, natural resources and shoreline, housing, public facilities, public utilities, recreation, transportation, and land use. HELCO's request for both an amendment of the State Land Use Boundary to the Urban District, and the request for an amendment of the County's zoning designation to general industrial conforms with the County General Plan LUPAG map designation for the site and applicable sections of the General Plan. The following are the goals, policies, and standards that apply to this project: Energy Policies • The County shall strive to assure a sufficient supply of energy to support present and future demands. Standards • New power plants shall incorporate devices which minimize pollution Public Utilities Goals • Ensure that adequate, efficient and dependable public utility services will be available ro users • Maximize efficiency and economy in the provision of public utility services (14) • To have public utility facilities which are designed to fit into their surroundings or concealed from public view Policies • Public utility facilities shall be designed so as to complement adjacent land uses and shall be operated so as to minimize pollution or disturbance. • Provide utilities and service facilities that minimize total cost to the public and effectively service the needs of the community. • Utility facilities shall be designed to minimize conflict with the natural - environment and natural resources. • Improvement of existing utility services shall be encouraged to meet the needs of users. • The County shall develop short- and long-range capital improvement programs and plans for public utilities within its jurisdiction and which are consistent with the County General Plan. Electricity Policies • The County should encourage electrical utility companies to develop a comprehensive plan for the generation, transmission, and distribution of electrical power to the various parts of the Islands. Standards • There shall be a minimization of obstruction of scenic views and vistas by electrical facilities. Land Use Goals • Designate and allocate land uses in appropriate proportions and mix and in keeping with the social, cultural, and physical environments of the County. Policies • Zone urban- and rural-types of uses in areas with ease of access to community service and employment centers and with adequate public utilities and facilities. • Promote encourage the rehabilitation and use of urban and rural areas which are services by basic community facilities and utilities. Industrial Land Use Goals • Designate and allocate industrial areas in appropriate proportions and in keeping with the social, cultural, and physical environment of the County. • Promote and encourage the rehabilitation of industrial areas that are serviced by basic community facilities and utilities. Policies • Through its zoning powers, the County shall locate industrial areas convenient to transportation facilities, and provide a variety of (15) industrial zoned districts and lot sizes, depending on the needs of the industries and the communities. 5. State Land Use Designation The site of the Puna Generating Station is currently designated by the State Land Use Commission (LUC) as part of the state's "Agricultural" district. HELCO is requesting through the County, an amendment of the site's Land Use District designation to the Urban District. The processing of the boundary amendment through the County is _ pursuant to Hawaii Revised Statute (HRS) Section 205-3.1, as amended, and Chapter 28 of the Hawaii County Code. They allow the County to amend State Land Use district boundaries for lands IS acres or less located in the State Land Use Urban, Rural, and Agricultural Districts. HELCO's request for an amendment of the State Land Use Boundary to the Urban District is reasonable and does not violate the standards for the Urban District of the State Land Use Boundaries as set forth in HRS 205-2. The standards used by the LUC for determining Urban District boundaries, as listed in HAR 15-15-18, and the relationship of the proposed project to them are discussed below. 1 It shall include lands characterized by "city-like" concentrations of people, structures, streets, urban level of services and other related land uses. 2. It shall take into consideration the following specific factors: A. Proximity to centers of trading and employment except where the development would generate new centers of trading and employment B. Substantiation of economic feasibility by the petitioner C. Proximity to basic services such as sewers, transportation systems, water, sanitation, schools, parks, and police and fire protection D. Sufficient reserve areas for urban growth in appropriate locations based on a ten-year projection 3. It shall include lands with satisfactory topography and drainage and reasonably free from the danger of floods, tsunami, unstable soil conditions, and other adverse environmental e,~`ects. 4. In determining urban growth for the next ten years, or in amending the boundary, land contiguous with existing urban areas shall be given more consideration than non-contiguous land, and particularly when indicated for future urban use on state or county general plans. 5. It shall include lands in appropriate locations for new urban concentrations and shall give consideration to areas of urban growth as shown on the state and county general plans. 6. It may include lands which do nor conform to the standards in paragraphs 1 to 5: (16) A. When surrounded by or adjacent to existing urban development B. Only when those lands represent a minor portion of this district 7. It shall not include lands, the urbanization of which will contribute toward scattered spot urban development, necessitating unreasonable investment in public infrastructure or support services. 8. It may include lands with a general slope of twenty percent or more which do not provide open space amenities or scenic values if the commission finds that those lands are desirable and suitable for urban purposes and that official _ design and construction controls are adequate ro protect the public health, welfare and safety, and the public's interest in the aesthetic quality of the landscape. The Puna Generating Site is currently a heavy industrial use that reflects the continuation of a use established by the sugaz operations that were discontinued in the 1980s. Slopes on the project site are minimal. The site does not lie in any flood or tsunami zones. The United States Department of Agriculture (USDA) Soil Conservation Service Soil Survey Report classifies the soils in the vicinity of the site as being in the Olaa series, and specifically the Olaa Silty Clay Loam (OaC). This series is characterized by moderately deep, moderately fine soil. Permeability is rapid, runoff is slow, and the erosion hazazd slight. A culvert adjacent to the road serving the site drains into a drainage ditch pazallel to the road. Standard on-site drainage improvements would accommodate any future intensification of the use of the site. HELCO will comply with all applicable regulations governing drainage. The location of the project site does not represent a significant adverse impact to scenic views or vistas, nor does it cause a significant adverse impact on the aesthetic quality of the landscape. The use of the site for generation and distribution of electricity does not significantly diminish the available supply of land used for agricultural activities, nor will it have any adverse impact on the remaining adjacent agricultural uses. The proposed project will not require extension of existing County or State infrastructure to the site and the project will not have any impact that will require the expenditure of public funds for infrastructure. HELCO and the Hawaii County Department of Water Supply (DWS) have sepazate groundwater wells on the Puna Generating Station site. The HELCO Puna Generating site has a minimal impact on any requirement for police and fire protection. (17) The site has no significant adverse impact on regional traffic and there is no mitigation measure recommended. The continued use of the site to generate and distribute electricity will not directly cause additional population growth on the Island of Hawaii. HECO is a subsidiary of Hawaiian Electric Company, Inc. (HECO), a company with publicly traded stock. The Public Utilities Commission (PUC) regulates HELCO. As a subsidiary of a publicly traded company, HELCO has access to the economic resources _ required to develop the project. HELCO can request the authority from the PUC to make expenditures for construction of the proposed facility and to recapture costs through the electricity rates paid by HELCO's customers. HECO is also able to issue bonds and stock to finance the project. No such request is contemplated in conjunction with this application. The reclassification of the site [o the Urban district will no[ impact the provision of sufficient service areas for other urban growth requirements. Approval of the "Urban" district designation would be consistent with approved urban land use reclassifications in the immediate vicinity of Keaau. The reclassification of the site to the Urban district will not contribute to scattered spot urban development, as it is in the midst of areas with urban type uses, and is adjacent to and in close proximity to existing urban designated lands and facilities. In addition to the standards for the Urban District set forth in HAR 15-15-18, the LUC considers specific criteria in making their decision as outlined in HAR 15-15-77. Those decision-making criteria for boundary amendments and the relationship of the proposed project to them are outlined below. I. The extent to which the proposed reclassification conforms to the goals, objectives, and policies of the Hawaii State Plan and relates to the applicable priority guidelines of the Hawaii State Plan and the adopted functional plans. 2. The extent to which the proposed reclassification conforms to the applicable district standards. 3. The impact of the proposed reclassification on the following areas of state concern: A. Preservation or maintenance of important natural systems or habitats B. Maintenance of valued cultural, historical, or natural resources C. Maintenance of other natural resources relevant to Hawaii's economy including, but not limited to agricultural resources D. Commitment of state funds and resources E. Provision for employment opportunities and economic development F. Provision for housing opportunities for all income groups, particularly the low, low-moderate, and gap groups 4. In establishing the boundaries of the districts in each county, the commission shall give consideration to the general plan of the county in which the land is located. (18) The Hawaii State Plan is a guide for future long-range development. It identifies the goals, objectives, policies, and priorities for the State; allocates limited resources; improves coordination among federal, state, and county agencies; and establishes a system for integrating all major state and county activities. The extent to which the HII.CO site conforms with the Hawaii State Plan and its related functional Plans and the extent to which the project conforms with the provisions of the County General Plan are discussed in preceding sections of this report. Site investigations and reconnaissance as well as consultation with the applicable - agencies revealed no significant natural resources, habitats, cultural, or historic resources at the project site. The generating station has not and will not have a significant adverse impact on any environmental resources. The reclassification of the site to the Urban district will not entail the removal of agricultural land from active production. HELCO's current full- and part-time staffing for the Puna Generating Station consists of three shifts with two employees per shift. Other HELLO staff visits the site, as required by specific tasks. The production of electricity provided by the Puna Generating Station will support the continued economic expansion of the Island of Hawaii and provide the necessary energy to support affordable housing programs as they are developed HELLO does not require expenditures by either the State of Hawaii or the County of Hawaii. HELLO is seeking to rezone the site to the County's general industrial district (MG), with a minimum lot size of 10 acres (MG-l0a). The County's general industrial district allows uses that are consistent with the power generating use established at the Puna Generating Station. HELLO plans to continue using the site to generate electricity and for related ancillary improvements. (These are currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988.) 6. County General Plan Designation A letter dated February 3, 1997, from the County Planning Director confirms "that HELCO's Puna Generating Station is located within the area designated as `Industrial' by the General Plan Land Use Pattern Guide (LUPAG) Map" HELCO's request for both an amendment of the State Land Use Boundary to the Urban District, and the request for an amendment of the County's zoning designation to general industrial conforms with the County General Plan LUPAG map designation for the site and applicable sections of the General Plan. 7. County Zoning The site is currently designated in the County's agricultural zoning district, and is zoned A-20. (19) HELCO is seeking to rezone the site to the County's general industrial district (MG), with a minimum lot size of 10 acres (MG-l0a). The County's general industrial district allows uses that are consistent with the power generating use established at the Puna Generating Station. HELCO plans to continue using the site to generate electricity and for related ancillary improvements. (These are currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988.) The uses permitted in the County's general industrial district do not violate the standards for the Urban District of the State Land Use Boundaries as set forth in HRS 205-2. The HELCO site is slightly over 10 acres in size. Under the current and the requested zoning, HELCO will not be able to subdivide the site. 8. Puna District Community Development Plan Community Management Associates, Inc. prepared the Puna Community Development Plan draft in June 1992. The County did not adopt the draft. 9. Special Management Area The site is not located within the area designated as the Special Management Area of the County of Hawaii, pursuant to Chapter 205A, Hawaii Revised Statutes, and applicable administrative rules of the County Planning Commission. C. PHYSICAL CHARACTERISTICS AND ENVIRONMENTAL SETTING OF THE PROPERTY AND SURROUNDING AREA Physical Characteristics/Environmental Setting 10. Description of Subject Property, Location, Climate, Topography, Slope, Soils (including size, shape, existing structures) The subject property is identified as TMK 1-6-03:93. It encompasses a total of 10.5 acres, and it has, to an extent, a triangular shape. The HELCO site is located at Keaau in the Puna District, County of Hawaii. The primary access to the Puna Generating Station site is from Mamalahoa Highway by Keaau Road. The site is located near the 300-foot elevation. The site is generally level with no significant grade or on-site undulations. The mean annual rainfall in the area ranges between 125 to 175 inches. Prior to HELCO acquiring the subject site, it was extensively disturbed by activity related to on-site grading and fill, construction, vehicular traffic, and sugar mill and related operations. (20) HELCO owned structures and improvements on the site are related to electrical generation and distribution. In addition to HELCO's structures, the County Water Department also has two water wells, a chlorinator, storage and pump facilities, and 10- inch diameter service lines. 11. Lava Flow Hazard Zone The United States Geological Survey (USGS) has established volcanic hazard zones for the Island of Hawaii for long-term planning purposes. The lava flow hazard zone _ designations are based on the percentage of the potential flow area that has been covered by lava flows during specific time periods, the frequency of past eruptive events, and the assumption that the rate of current volcanic activity will continue for the next several decades. Zone 1 reflects the greatest volcanic hazard and Zone 9, the lowest. The Puna Generating Station is located within Lava Flow Hazard Zone 3, which is also the zone designation applicable to Hilo. The entire Island of Hawaii is susceptible to earthquakes originating in fault zones under and adjacent to the island. The County Building Code designates the entire Island of Hawaii as being within the Earthquake Zone 3 (based on a scale of zones with increasing risk from 0 to 4, due to seismic occurrence and danger). The Zone 3 designation requires that structural design requirements be met in conjunction with the design and construction of any structure. 12. Distance from Coastline The site is over 3 miles from the nearest coastline. 13. Agricultural Lands of Importance in the State of Hawaii (ALISH) Designation Consultation with the State Department of Agriculture indicates that the Agricultural Lands of Importance [o the State of Hawaii (ALISH) system do not have an ALISH rating for the site on map H-66, dated January 1977. 14. United States Department of Agriculture, Natural Resources Conservation Services Soil Service Report Soil Type The United States Department of Agriculture (USDA) Soil Conservation Service Soil Survey Report classifies the soils in the vicinity of the site as being in the Olaa series, and specifically the Olaa Silty Clay Loam (OaC). This series is characterized by moderately deep, moderately fine soil. Permeability is rapid, runoff is slow, and the erosion hazard slight. 15. Land Study Bureau Soil Rating Consultation with the State Department of Agriculture indicates that the Land Study Bureau Detailed Land Classification, Island of Hawaii (November 1965, map 654) indicates that the site has a "U" or urban use rating, reflecting the industrial use of the (21) area. Former sugarcane lands surrounding the former Puna mill site have an overall productive rating of "C" indicating fair productivity potential for most crops. 16. Flood Insurance Rate Map (FIRM) Designation The United States Army Corps of Engineers' Flood Insurance Rate Man (FIRM) designates the site as "Zone C: ' Zone C is an area characterized with minimal flooding. 17. Existing Drainage Ways or Improvements A culvert adjacent to the road serving the site drains into a drainage ditch parallel to the road. Standard on-site drainage improvements would accommodate any future intensification of the use of the site. HELCO will comply with all applicable regulations governing drainage. 18. Air/Noise/Groundwater/Water Quality a. Air Quality HELCO Generating Station is in compliance with all applicable federal and state regulations related to air quality. Appendix C is a report titled "Puna Generating Station, Air Quality Impacts," prepared by Jim Clary and Associates. b. Noise Hawaiian Electric Company (HECO) personnel measured background ambient noise levels at the Puna Generating Station. HECO's measurements indicate that the Puna Generating Station is in compliance with the State DOH 70 dBA standard at the property lines. Title 11, Chapter 46 Community Noise Control, adopted by the State Department of Health (DOH) in September 1996. On the Island of Hawaii, the DOH regulates noise from on-site activities. State DOH noise regulations are expressed in maximum allowable property line noise limits for areas zoned preservation residential, apartmenUcommercial, and agriculturaUindustrial. The noise limits established for these zoning classes are shown in Table Two. These noise limits cannot be exceeded for more than 2 minutes in any 20-minute time period. Because the project site and surrounding areas are located on lands zoned for agricultural use, the DOH noise limits are 70 dBA for both the daytime and nighttime periods. (22) Table Two Maximum Permissible Sound Levels in Decibels (dBA) Zoning Class A Class B Class C Residential and Apartment, Hotel, Agriculture, Time Preservation and Business Industrial Daytime (7 a.m. to 10 p.m.) 55 fi0 70 Nighttime (10 p.m. to 7 a.m.) 45 50 70 Notes: a) Standards shall apply to the following excessive noise sources: stationary noise sources and equipment related to conswction, agriculture, and industrial activities. b) Maximum permissible sound levels shall apply to any excessive noise source emanating within the specified zoning district, and at any point at or beyond the property line of the premises. c) Noise levels shall not exceed the allowable levels for more than 10 percent of the time (L~o) within any 20-minute period, except by permit or variance issued under HAR 11-06-7 and 11- 46-8. d) The allowable noise for impulsive sound shall be 10 dBA above the values in this table. Nawaii Administrative Rules, Title 1 Chapter 46 Construction noise also falls under permitted activities that can exceed the levels shown in Table Two for a specified period of time. There are, however, permit restrictions for construction activities. These are: • No construction activities that produce noise levels in excess of the values in Table Two at or beyond the property line are allowed before 7 a.m. or after 6 p.m., Monday through Friday. • No construction activities that produce noise levels in excess of the permissible sound levels shown in Table Two at or beyond the property line are allowed for the hours before 9 a.m. and after 6 p.m. on Saturdays. • No construction activities that exceed the noise levels specified in Table Two are allowed on Sundays and on holidays. c. Groundwater HECO environmental department personnel support HELCO in matters related to federal and state regulation related to groundwater. HECO indicates that the HELCO Generating Station is in compliance with all applicable federal and state regulations related to groundwater. (23) The Puna Generating Station is situated over the Keaau Aquifer System. The Hilo-Keaau region is underlain by relatively young lava flows, mostly less than 10,000 years old, from Mauna Loa. Regionally, the lavas are highly permeable, and lazge volumes of groundwater under low gradients pass through them. At the Puna Generating Station, all data indicators suggest that groundwater is pazabasal, and that the saturated aquifer is bounded below by an aquitazd, which is probably an ash bed. Parabasal groundwater is hydraulically connected to the basal lens but rests on a low permeability stratum rather than seawater. The estimated boundary between basal and parabasal ground water lies about 1.3 miles east of the Puna Generating Plant and passes through Paradise Pazk. - Parabasal groundwater is hydraulically connected to the basal lens but rests on a low permeability stratum rather than seawater. The HELLO and DWS wells at the Puna Generating Station have never displayed salinity of more than 10 parts per million. (Source: Unpublished report tilted "Pena Water Resources Investigations and Permitting..." Mink and Yuen, Inc., September 1996.) The State Water Resources Protection Plan (Volume II Appendix, 1990, by G.A.L. Yuen and Associates) indicates that over the 8 miles between Hilo and the contact of Mauna Loan and Kilauea lavas neaz the Puna Power Plant, approximately 1,700 million gallons per day (mgd) of fresh groundwater flow either in a seaward direction or southwazd into the Kilauea Aquifer Sector. The Water Resource Protection Plan indicates that for the Hilo Aquifer System, rechazge is 793 mgd and for the Keaau Aquifer System, it is 898 mgd. Estimates by Takasaki indicate that 1,000 mgd moves southwazd into the Kilauea Sector, leaving 700 mgd to dischazge from Mauna Loa lavas along the coast. The Groundwater Protection Plan indicates that the sustainable yields for the Hilo Aquifer System and the Keaau Aquifer System are 347 and 393 mgd, respectively. (Source: Ibid., Mink and Yuen, Inc., September 1996.) Data available from various published and public sources indicates that the current draw from the Keaau Aquifer is less then 20 mgd. Data from the State Commission on Water Resource Management indicates that the capacity of existing wells in the aquifer total 27 mgd. HELLO and the Hawaii County Depaztment of Water Supply (DWS) have sepazate groundwater wells on the Puna Generating Station site. The following describes the HELLO and DWS wells and ancillary system components. • HELLO Information provided by HELLO indicates that the three HELLO wells on the generating station site use an average of 12.1 million gallons per day (mdg). HELLO uses groundwater for cooling water pumps, to cool fans, generators, the existing combustion turbine, compressors, pumps, air heater wash, various fire hoses on each floor, and all the wash-down and cooling needs. HELLO provides water to the adjacent papaya operation, which was previously owned by AMFAC, prior owner of the HELLO site. The papaya operation also uses DWS water service provided through a meter located on the generating station site. (24) During periods when I;~I,CO's steam plant is not operating and/or when HELLO shuts down the three deep wells, the papaya operation provides HELLO county water to supply the various cooling water pumps and to meet HELCO's other water needs at the Puna Generating Station. Information provided by HELLO also indicates that use of groundwater by the Puna Generating Station has no adverse affect or impact on the underlying aquifer. Information provided by HELLO indicates that HELLO currently complies with and in the future will continue to comply with all state and federal requirements applicable - to the use of groundwater. DWS DWS has two wells on the generating station site, Olaa wells A and B. In addition, DWS has a chlorinator station and pipeline easements on the site. Water from Olaa wells A and B and water from a third DWS well, Olaa C (located at a site up gradient of the generating station near the former dispensary camp) is providing water to DWS customers in the Keaau-Mountain service area. This system has a linear service area essentially following the alignment of the Volcano Highway from Keaau to Glenwood, with a side line providing service to Paradise Drive. Until Olaa well C was completed, water from Olaa wells A and B was pumped through a series of booster pumps and storage tanks to the uppermost service area in Glenwood. DWS continues to have the capability of pumping water up gradient from Olaa wells A and B, but seeks to minimize this in order to reduce system pumping costs. Since the Olaa well C is up gradient of wells A and B, it is the primary source of water for the DWS service area. The most current data submitted to the State Commission on Water Resource Management, for the month of December 1997, indicates that DWS Olaa wells A and B pumped a combined total of 2.5 million gallons per month. Olaa C well pumped 26.4 million gallons in the same month. d. Water Quality As noted previously, the HELLO and DWS wells at the Puna Generating Station have never displayed salinity of more than 10 parts per million. (Source: Unpublished report tilted "Puna Water Resources Investigations and Permitting..." Mink and Yuen, Inc., September 1996.) This is attributable to the estimated boundary between basal and parabasal ground water being about 1.3 miles east of the Puna Generating Plant. Parabasal groundwater is hydraulically connected to the basal lens but rests on a low permeability stratum rather than seawater. Consequently, the infiltration of seawater is minimal. As discussed in a subsequent section concerning wastewater disposal, HECO environmental department personnel support HELLO in matters related to federal and state regulation related to wastewater disposal. HECO indicates that the HELLO Generating Station is in compliance with al] applicable federal and state regulations (25) related to wastewater disposal. Information provided by HECO also indicates that wastewater disposal associated with the Puna Generating Station has no adverse affect or impact on the underlying aquifer. Historic Resources: 19. Existing Archaeological, Cultural or Historic Sites on the National Hawaii Register The HELCO Puna Generating Station site has no archaeological, cultural or historic sites _ or structures of historical significance. This is confirmed by correspondence from the state agency responsible for archaeological, cultural or historic sites and structures. A letter dated September 21, 1988, signed by William W. Paty, Chairperson, Board of Land and Natural Resources, commenting on Special Permit Application 88-22 states, in part: "Our Department's Historic Sites Section indicates that since this application only requests continued use of the existing plant facilities, there will be "no effect" on significant historic sites." In March 1997, CH2M HILL requested a written determination from the Historic Preservation Division of the Department of Land and Natural Resources that the State Land Use amendment and County rezoning change will have no effect on any significant sites on HELCO's property. A letter dated April 14, 1997, signed by Don Hibbazd, Administrator, State Historic Preservation Division, states, in part: "Because the area has been so extensively disturbed we believe that there are no significant historic sites remaining on the subject property. We thus believe that the proposed rezoning and boundary designation changes will have "no effect" on historic sites" Through the eazly-1980s for an unknown period of time, sugar was extensively cultivated in the azea surrounding the HELCO Generating Station site and the subject site was used for sugar milling. Prior to, during the establishment of the aforementioned uses and since the establishment of HELCO's generating and related uses in 1988, there are no known traditional gathering activities and/or cultural practices as identified by Article XII, Section 7 of the Hawaii State Constitution affecting the subject property. Natural Resources: 20. Existing Flora/Faunal Resources (any native or exotic plants, any listed or candidate endangered species) a. Flora The Puna Generating Station site has been used for sugar milling for almost 100 years, and for power generation for a decade, and has been extensively disturbed. The site does (26) not have any native, listed or candidate endangered flora. Within the fenced portion of the Puna Generating Station, vegetation is composed of planted landscaping. A mixed grass fringe is found on the west, north, and east sides of the site. The mixed grasses are all introduced such as California, molasses, and elephant grasses; a mix of weedy species; and some gazden escapees such as avocado. b. Fauna CH2M HILL consulted with the United States Department of the Interior, Fish and _ Wildlife Service (USFWS), Pacific Islands Ecoregion. An April 24, 1998 letter from a representative of indicate that the Hawaiian hawk, `Io (Buteo solitarius), and the Hawaiian hoary bat, Ope`ape'a (Lasiurus cinereus sematus), have been sighted in the proximity of the Puna Generating Station. The letter goes on to state: "No significant adverse impact to fish and wildlife resource are expected to result from the proposed zoning change." Based on on-site observations, the only known rare or endangered native avian resource that has been identified is native migratory specie, the Hawaiian Stilts (Himantopus mexicanus knudsem), observed on the edge of a small puddle adjacent to the main paved driveway into the generating station. The puddle is not a habitat area for the Hawaiian Stilts. This species is listed as endangered by the USFWS and by the State of Hawaii Division of Forestry and Wildlife. Based on on-site observations, the only known rare or endangered native mammalian resource that has been identified at the generating site is the Hawaiian hoary bat, Ope'ape'a (Lasiurus cinereus semotus). This species is listed as endangered by USFWS and by the State of Hawaii, DLNR Division of Forestry and Wildlife. At night, the bats feed on flying insects attracted by night lighting. The generating station site and structures aze not a habitat azea for the bat. 21. Scenic or Coastal Resources There are no scenic or coastal resources affected by the HELCO site. The Natural Beauty element of the County's General Plan identifies sites or areas that are considered to be a scenic resource. The HELCO site and immediately surrounding area are not listed as a scenic site. The site is over three (3) miles from the nearest coastline, and does not affect coastal resources. Social-Economic Characteristics: 22. Social Settlement Pattern for the Area Keaau is located at the junction of two major highways in Puna, and is thus centrally located. A central commercial area with surrounding "pockets" containing concentrations of people characterizes Keaau's settlement pattern. The area immediately surrounding the HELCO site has a mix of urban types of land uses in the vicinity of the site. The HELCO (2~) site and surrounding area's settlement pattern is historically and functionally an extension of the Keaau Town center's urban area. The state has approved urban land use reclassifications in the immediate vicinity of Keaau. Approximately 660 acres of land were included in a 1994-land use boundary amendment. With subsequent county rezoning, the amendment will lead to an expansion of Keaau village over time, as infrastructure is developed and as the market demand for urban uses materializes. The expansion includes a parcel north of Keaau is on the western side of the Mamalahoa Highway, on the opposite side of the highway from the _ HELCO site. (The reclassification of the 600 acres of land involves land owned by W. H. Shipman, Limited. The 600 acres is a portion of approximately 2,000 acres in and azound Keaau, which Shipman has planned as part of the "Conceptual Keaau Development Plan." Shipman proposes to develop the 2,000 acres over-a period of 20 or more years.) As discussed in section 25, "Land Use," several urban uses have been established in the immediate vicinity of the Puna Generating Station. The County Planning Commission has approved Special Permits for several parcels in the vicinity of the HELCO site. The Special Permits allow urban type uses that include a flower packing facility, a papaya packing facility, and a church school. Sites with urban uses in some proximity to the HELCO also include astate-assisted housing project, permitted under statutory pre- exemptions of land use requirements, and a former sugar plantation housing subdivision. Section 25 also discusses TMK 1:6:03:5, a pazcel immediately adjacent to the Puna Generating Station. In 1997, the County approved redesignation of a 14.3 acre portion of TMK 1:6:03:5 to the Urban District and concurrently rezoned the aforementioned area to alight industrial (ML) zoning district designation. Subsequent to the 1997 rezoning approval, the property owner submitted a second rezoning application, now pending final County Council action. The pending rezoning seeks to change the ML zoning district designation to the "Industrial-Commercial Mixed" (MCX) district designation. The MCX zoning district was created in late-1996 and would allow a mix of commercial and light industrial uses. Urbanization of the HELCO Puna Generating station will not contribute to scattered spot urban development, as it is in the midst of areas with urban type uses, and is proximal to existing urban faciliti:.s. 23. Economic Resources of the Area Historically, the Puna District has had agricultural activities as the primary economic activity. Through the 1980s, sugar provided significant employment in the district. With the termination of sugar cultivation, diversified agriculture has been the principal primary economic activity located in the district. Industrial activities in the Puna District aze limited, and include processing of agricultural products, electric power production, and activities located at the Shipman Industrial Park. (28) Tourism in the Puna District is limited, with the principal tourist destination being the Volcanoes National Pazk. The employed residents of the towns and subdivisions in the Puna District generally work in Hilo. The lazgest of these towns is Keaau, followed by Pahoa. Both of these towns serve as commercial and service centers for residents of the Puna District. 24. Land Values _ The Puna District's residential lands offer some of the lowest cost house lots in the state. The low cost of residential lots is attributable to the supply of unimproved residential lots in the Puna District exceeding the demand for undeveloped lots. The excess of supply relative to demand keeps the price of unimproved lots depressed. Commercial and industrial land values are typically lower in the Puna District than in Hilo. This is attributable to Hilo having a larger population base and being closer to transportation facilities, such as the Hilo airport and hazbor. Since the Puna Generating Station is apre-existing facility, any impact that the generating station would have on sunrounding land values would have already occurred and be reflected in current property values. HELLO does not contemplate selling the Puna Generating site at any time in the foreseeable future. Surrounding lands: 25. Land Use Keaau is located at the junction of two major highways in Puna, and is thus centrally located. A central commercial area with surrounding "pockets" containing concentrations of people chazacterizes Keaau's settlement pattern. The area immediately surrounding the HELLO site has a mix of urban types of land uses in the vicinity of the site. The HELLO site and surrounding area's settlement pattern is historically and functionally an extension of the Keaau Town center's urban area. A property immediately adjacent to the HELLO site, identified by TMK 1:6:03:5, was subject of County land use approvals in 1997. A County land use boundary amendment, approved in 1997, reclassified a 14.3 acre portion of TMK 1:6:03:5 to the state Urban District boundary, with the rest of the parcel remaining in the state Agricultural District. TMK 1:6:03:5 was concurrently rezoned in 1997 to a three-acre minimum lot size agricultural zoning designation, with the Urban portion of the property rezoned to a three- acre minimum lot size limited industrial district zoning designation. Subsequent to the 1997 rezoning approval, the property owner submitted a second rezoning application to reclassify the property to two new zoning district designation that were created pursuant to County's revised zoning ordinance enacted December 7, 1996. The second rezoning (29) request, currently pending County Council action, seeks to reclassify the portion of the TMK 1:6:03:5 in the state's Agricultural District to the County's "Family Agricultural" (FA) zoning district, with a minimum lot size of three acres. The 1998 rezoning requests that the remaining 14.3 acres in the state's Urban District be reclassified to the County's "Industrial-Commercial Mixed" (MCX) district designation, with a minimum lot size of 20,000 square feet. The FA zoning district is an agricultural zoning district designation, and the MCX zoning district allows a mix of commercial and light industrial uses. The County Planning Commission has also approved Special Permits for several other _ parcels in the vicinity of the HELCO site. The Special Permits allow urban type uses that include a flower packing facility, a papaya packing facility, and a church school. Sites in some proximity to the HELCO with urban uses also include astate-assisted housing project, permitted under statutory pre-exemptions of land use requirements, and a former sugaz plantation housing subdivision. 26. Zoning The site HELCO is currently designated in the County's agricultural zoning district. The site is currently zoned A-20. HELCO is seeking to rezone the site to the County's general industrial district (MG), with a minimum lot size of 10 acres (MG-l0a). HELCO wants to rezone the site from an agricultural zoning designation to the County's general industrial designation, as the current use of the site is consistent with the uses permitted under the general industrial zoning district designation. HELCO plans to continue using the site to generate electricity and for related ancillary improvements. (These are currently the use permitted by Special Permit No. 686 approved by the Hawaii County Planning Commission on November 15, 1988.) D. PUBLIC FACILITIES AND SERVICES 27. Description of Access The primary access to the Puna Generating Station site is from Mamalahoa Highway via Keaau Road. Mamalahoa Highway (State Route 11, elsewhere referred to as Route 19 and 190 and also known as Hawaii Belt Road) is a major arterial serving most of the Island of Hawaii. Within the vicinity of the HELCO site, Mamalahoa Highway is afour- lane highway that runs generally in the north-south direction. Keaau Road is a private mad providing access from Old Volcano Road to the existing HELCO Generating Station. The two-lane Old Volcano Road runs parallel and east of Mamalahoa Highway. Keaau Road crosses Old Volcano Road. (30) 28. Availability of Water Water is available at the HELLO Puna Generating Station site. Both HELLO and the Hawaii County Department of Water Supply (DWS) have separate groundwater wells on the site. Section 18-c, concerning "groundwater," contains an extensive discussion on the topic. 29. Wastewater Disposal _ HECO environmental department personnel also support HELLO in matters related to federal and state regulation related to wastewater disposal. HECO indicates that the HELLO Generating Station is in compliance with all applicable federal and state regulations related to wastewater disposal. Information provided by HECO also indicates that wastewater disposal associated with the Puna Generating Station has no adverse affect or impact on the underlying aquifer. Information provided by HECO indicates that the Puna Generating Station has four existing wastewater flows, described below. • Non-contact condenser cooling water, discharged from the condenser comprises approximately 467,000 gallons per hour (gph). This water is discharged into a re- injection well located off-site, and is permitted by underground injection control (UIC) permit No. UH 1438. • Auxiliary cooling water discharge comprises approximately 9,300 gallons per hour (gph). Currently, this water is disposed into aditch/culvert and discharged off-site. HELLO indicates it is considering a plan to isolate and recycle (i.e., re- circulate) all flows out of the existing auxiliary cooling water pumps through a service water cooler. • Currently, sanitary wastewater cesspool discharge comprises approximately 30 gph. • Industrial wastewater discharge varies. Industrial wastewater receives primary treatment at the Puna Generating Station, and is thin trucked to the Hill Generating Station in Hilo. It is further treated at the Hill Station and discharged to the Hill facility's injection wells, pursuant to existing UIC permits UH 1241 and LJH 1242. 30. Solid and Hazardous Wastes The County does not provide solid waste pickup service. The County of Hawaii has a transfer station in the vicinity of Keaau. The Hilo LandFill will be replaced by the West Hawaii landfill at Puu Anahulu. Solid waste generated by HELLO at the Puna Generating station is recycled to the extent practicable, with the remainder being disposed of at the County landfill. HELLO Generating Station is in compliance with all applicable federal and state regulations related to the disposal of solid waste. (31) Waste identified as hazazdous is disposed of in accordance with federal and state regulatory requirements. Currently, hazardous waste from the Island of Hawaii is shipped to the U.S. mainland for disposal. 31. Police and Fire Protection The HELCO site does not impact the demand for police and fire protection. Stations located in both Keaau and Hilo provide county police and fire protection services. HELCO personnel are also trained for emergency situations including fires and first aid. _ As noted elsewhere, a chain link fence surrounds the HELCO site. 32. Schools The HELCO site does not impact the demand for schools. The State Department of Education is currently constructing sepazate elementazy and high schools in the immediate vicinity of Keaau. 33. Pazks The HELCO site does not impact the demand for park space. The County's Shipman Pazk currently serves the area. Either the development of sepazate park sites or expansion of the existing Shipman Pazk will accompany expansion of Keaau. 34. Other Utilities and Services (telephone/electricity) The Puna Generating Station is an essential element of HELCO's electrical power generation capacity for Hawaii Island customers. HELCO provides electrical service to [he Puna Generating Station site. The HELCO site does not impact the demand for telephone service. GTE Hawaiian Telephone serves the HELCO site and surrounding area from its Keaau station. E. ENVIRONMENTAL ASSESSMENT AND ANALYSIS 35. Relationship Between Local Short Term Uses of Environment and Maintenance and Enhancement of Long Term Productivity Short-term uses of the biophysical components of the environment include direct construction-related disturbances and direct impacts associated with an increase in activity that occurs in less than 5 years. Long-term uses of the environment include those impacts occurring over a period of more than 5 years, including permanent resource loss. No short-term changes are anticipated at the HELCO Puna Generating Station that will impact components of the environment. Through the year 2017, no long-term changes are anticipated at the HELCO Puna Generating Station that will impact components of the environment. (32) Beyond the yeaz 2017, and under unforeseen circumstances prior to the yeaz 2017, the Puna Generating Station's generating capacity may be expanded. One impact associated with possible future expansion of the generating capacity is the change in the visual environment. A second impacts associated with any future expansion are related to air emissions produced by the facility decreasing the criteria pollutant increments available for future new sources under the Prevention of Significant Deterioration (PSD) regulations. Electrical energy is a resource that has become an indispensable part of life. Electric _ utility companies have the responsibility of providing reliable electric service at a reasonable cost to the consumer. Every effort should be made to conserve electricity, and new sources of energy production also need to be developed. As it becomes older, equipment runs less efficiently, uses more natural resources, and results in higher costs to the user. On the Island of Hawaii, population increases and the planned retirement of older equipment are creating the need for additional electrical generating capacity. The population of the Island of Hawaii has grown dramatically over the last two decades. Overall population and economic growth on the Island of Hawaii is expected to continue in the foreseeable future. 36. Mitigate Measures Proposed to Avoid, Minimize, Rectify or Reduce Impact No development is currently planned or proposed in conjunction with the requested changes in the state and County land use designations. Since no development is currently planned or proposed, there are no impacts to reduce, minimize and rectify. Therefore, no mitigation measures are proposed. 37. Alternatives to the Proposed Development No development is can-ently planned or proposed in conjunction with the requested changes in the state and County land use designations. Since no development is currently planned or proposed, alternatives are not relevant. 38. Irreversible and Irretrievable Commitments of Natural Resources Involved if Proposed Action Implemented Irreversible and irretrievable resource commitments are related to the use of nonrenewable resources and the effects that use of these resources will have on future generations. Irreversible effects primarily result from use or destruction of a specific resource (for example, energy and minerals) that cannot be replaced within a reasonable time frame. Irretrievable resource commitments involve the loss in value of an affected resource that cannot be restored as a result of the action (for example, extinction of a threatened or endangered species). The Puna Generating Station is an existing use on a site that has been actively used for power production over the past decade, and for sugar milling prior to that. No new development is currently planned or proposed in conjunction with the requested changes (33) in the state and County land use designations. Since the HELLO Puna Generating Station is an existing use and development, and no new use or development is currently planned or proposed, there will not be any additional irreversible and irretrievable commitment of natural and fiscal resources. HELCO's decision to continue the use of diesel fuel, rather than other fuel sources, is based on the economics of providing the electricity. HELLO is committed to the development of feasible, cost-effective alternative fuels and power sources and increased conservation measures to lessen dependency on imported fossil fuels. F.

(ATA) to Identity the traffic impad of the existing Hawaii Electric tight Company's (HELLO) Puna generation facility, identified as (fMIQ: 1-6-03:93. HELLO is presently requesting to rezone the site of the Puna generation facility at the County level from agricultural use to Industrial use and at the State level ftom agricultural use to urban use. Inftially, the Puna Generating Station was developed as an andllary use with the operation of the former Puna Sugar Mili; this activity was previously permitted as agricultural activity. The generated electricity was utilized by sugar operations and employee-residents. With the cessation of sugar operations, HELLO acquired suffident right-of-way and was granted a Spedal Pennft by the County of Hawaii to continue the generation of power. The Spedal Permft was required since the power generation became the primary use for the sfte as it was no longer assodated with agriculttnal activity. The requested State and Courrty rezonings would better reflect the actual use of the Puna generation fadlity site. The site of the existing fadlity is located at the former Puna Sugar Mta. Primary access to the site is from Mamalahoa Highway via Keaau Road. Flgure 1 shows the general roadway system In the vidnity of the proposed expansion site. The existing faditty has 37 MW of generating capadty. The staffing of the fadlity consists of 3 shifts with 2 employees per shift. The delivery of diesel fuel Is currently 21-49 trips per week. HEl CO currently has no expansion plans for the fadlities located at the Puna generating facliriy. REPIV TO- OFFICES IN 301 BLMMVER STREET. B1.11TE BQ1 •,-,ONOLULU. I'I>WYII 9BB.~1~3D3. I HGJGLULU.

Mr. AI Lono Lyman CH2M H11I May 11, 1998 Purpose and Scope The purpose of the study is to analyze the traffic impacts of the existing HELLO facility on the local roadway system. The foilovring are traffic scenarios which are analyzed in this study: • Existing Year 1997 Conditions • Year 2001 Base Conditions This study analyzes the two intersections of Mamalahoa Highway at Keaau Road and Old Volcano Road at Keaau Road, which are directly affected by the HELLO facility traffic. IXISTING CONDITIONS The following is a brief discussion of the existing major roadways in the immediate vicinity of the expansion site, and the current traffic operating conditions at the two key intersections. Mamalahoa Highway -Mamalahoa Highway (State Routes 11, 19 and 190), also known as Hawaii Belt Road, is a major arterial serving most of the island of Hawaii. Within the vicinity of the HELLO expansion site, Mamalahoa Highway is a four-lane highway which runs generally in the north-south direction. North of Keaau Town, Mamalahoa Highway Is a divided highway with a posted speed limft of 55 miles per hour (mph). Within Keaau Town, Mamalahoa Highway is an undivided, tour-lane highway with a reduced speed limit of 35-mph. Keaau Road -Keaau Road is a private road providing axess from Old Volcano Road to the existing HELLO generation tadlity. Between Mamalahoa Highway and OId Volcano Road (approximately 50 teen, Keaau Roadie maintained by the Co!:nty:of Hawaii. The two-lane gravel road also serves a QgM Industrial complex located Just north of the HELLO tadlity. Keaau Road Is controlled by stop signs at the Intersections at Old Volcano Road and Mamalahoa Highway. Old Volcano Road - Within the general vidnity of the. study area, the two-lane Old Volcano Road runs parallel and east of Mamalahoa Highway. North of Keaau Road, the Old Volcano Road serves a light industrial complex and private properties. South of Keaau Road, the Old Volcano Road provides axess to the residential areas of Keaau Town. Figure 2 shows the existing geometrics at two analyzed intersections. Weekday AM and PM peak period traffic counts were conducted by ATA at the two existing analyzed Intersections. Figure 3 shows the existing traffic volumes at the two -2- Mr. AI L.ono Lyman CH2M Hill May 11, 1998 intersections. Manual turning movement counts were conducted during the morning and evening peak periods on March 19 and 20, 1997. During the morning AM peak period, the peak direction of traffic flow on Mamaiahoa Highway is in the northbound direction with approximately 2,640 vehicies during the peak hour and approximately 640 peak hour vehicles in the southbound direction. During the afternoon PM peak period, the peak direction of flow Is in the opposite direction with approximately 1,800 peak hour vehicles in the southbound direction and approximately 770 peak hour vehicles in the northbound direction. It was observed that, during the PM peak period, a relatively high number of southbound vehicles (267 vph) on Mamaiahoa Highway turn left onto Keaau Road and then turn right onto the Old Volcano Road. If is assumed that most of these motorists are bound for the residential areas of Keaau Town. Based on the existing traffic count data, the number of vehicles that utilize Keaau Road serving the HELCO facility area is relatively low. During the AM peak hour, only 46 vehicles per hour (vph) were observed, with 12 vph in the westbound direction and 34 vph in the eastbound diredion. During the PM peak hour, only 33 vph utilize Keaau Road with 27 vph in the westbound direction and 6 vph in the eastbound diredion. Level of service (LOS) is a qualitative measure used to describe the conditions of traffic tlow, ranging from free-flow conditions at LOS A to congested conditions at LOS F. The 1894 biotn ^•v Gacadty h"anual - Soedai Report 209 method for calculating delays and corresponding levels of seMce at stop•controlled Irttersedlons was utilized in this study. Level of service definitions tor~slgnatized and stop-controlled intersedions are provided in Table 1. Flgure 3 also shows the levels of service at the two existing IMersedions. Results also show that, during the AM peak hour, the southbound left tum movement trom Mamaiahoa Highway to Keaau Road Is operating at lAS F. Long detays to this partlculai movement are mainly due to the high amount of northbound opposing vehides on Mamaiahoa Highway. The westbound left-tum movement from Keaau Road to Mamaiahoa Highway is also operating at LAS F during the AM peak hour, but this only affeds a small number of vehides (only one vehide during the peak hour was observed). The remaining movements at both intersections are all operating at acceptable levels of service (LOS A, B, C or D). -3- .WBT,N. T8t1T8UM, C'6880C,eTlB. ,IVC ^ CNL INdV!!9 !WVlTC„! Mr. AI Lono Lyman CH2M Hill May 11, 1998 Results also show that during the PM peak hour, only the westbound left-turn from Keaau Road to Mamalahoa Highway is operating at an undesirable level of service (LOS F). However, similar to the AM peak hour, only one vehicle during the PM peak hour was observed affected. Although the number of PM peak hour southbound left-turn vehicles (267 vph) from Mamalahoa Highway to Keaau Road is much higher than the AM peak hour (122 vph), this movement is operating at an acceptable level of service (LOS B) due to the much lower number of northbound opposing vehicles. The intersection of Old Volcano Road and Keaau Road is operating at LOS A and B during the AM and PM peak hours, respectively. YEAR 2001 BASE CONDITIONS The Year 2001 Base forecast of traffic conditions is based on existing traffic volumes plus expected ambient growth in traffic caused by regional growth throughout the entire island of Hawaii. The ambient traffic growth rate, which was applied to existing traffic volumes to estimate Year 2001 traffic volumes, is based on historical traffic counts conducted by the State of Hawaii, Department of Transportation (HDOT). Based on historical HDOT traffic counts in the vicinity of the proposed expansion, an approximate 1% per year traffic growth rate is applied. The resulting Year 2001 Base Vaffic volumes and level of service results are shown on Figure 4. Since Year 2001 operations at the Puna generation facility are not expected to change, the future traffic generation of the HELCO facility would remain the same as the existing trip generation as given In Table 2.. With the expected overall traffic growth in the area, the level of service results are similar to the existing 1997 operating conditions. The westbound Jett-tum from Keaau Road to Mamalahoa Highway will continue to operate at LOS F during both.the AM and PM peak hours, and again, only a'small number of veh(des will be atfeoted. The southbound left-. tum from Mamalahoa Highway to Keaau Road will continue to operate at LOS' F during the AM peak hour while the PM peak hour level of seMce will deteriorate from LpSB to LOS C, which is still within the acceptable range. Table 3 summarizes the level of service results. CONCLUSIONS AND RECOMMENDATIONS At the Intersection of Mamalahoa Highway and Keaau Road, the southbound left-turn movement is currently operating at LOS F during the AM peak hour. This is due to the fact that the opposing northbound traffic volume on Mamalahoa Highway (Hilo bound) is very high during this Ume of day. Also, the westbound left-tum movement from Keaau -4 Mr. AI Lono Lyman CH2M Hill May 11, 1998 Road to southbound Mamalahoa Highway is operating at LOS F during both the AM and PM peak hours. However, it should be recognized that only a small number of vehicles is being affected (only 1 vehicle was observed during both the AM and PM peak hours). Based on historical growth trends in the area, traffic volumes are expected to increase by approximately 1% per year. in the Year 2001 Base forecast, the peak hour operations at both intersections are expected to be similar to existing Year 1997 operating conditions. It is recommended that no improvements are necessary at the intersection of Mamalahoa Highway and Keaau Road. Although the westbound left-tum is currently operating at an undesirable level of service, only a very small number of vehicles are affected. And, although the southbound left-turns from Mamalahoa Highway to Keaau Road are operating at an undesirable level of service, this only occurs during the morning peak period when the opposing northbound approach is heavy. Based on the traffic counts conducted, most of these vehicles are bound for Keaau Town which can also be accessed by Ahoa Street and Kalapana Road further south.

Existing Conditions 1.7. Topography The Puna Generating Station is located on the Island of Hawaii in the easterly part of the Island, which is referred to as the Puna area. The station is located about 16 kilometers (km) south of Hilo, near the town of Keaau. About 16 km west of the Padfic Ocean, ft is located in the upper Waiakea forest reserve. Other than sparse pockets of development, abandoned sugar cane fields surround the generating station. Terrain in the area can be described as mountainous due to the proximity of Mauna Loa Volcanic Mountain. Terrain elevations in this area range from 61 meters (m) near the Pacific Ocean to 570 m above mean sea level (MSL) within a 13-km radius of the fadlity. The elevation of the Puna fadlity is approximately 67 m above MSL. 1.2. MeteorologylClimate The Island of Hawaii is located in the trade wind band, a region in the north Padfic, dominated by a semi-stationary high pressure center north of Hawaii. Wind dreulation around the high pressure area is dockwise and outward from the center. The trade winds come to Hawaii from the northeast to the east with the orographic channeling effect in some locations modifying the intensity and direction of the winds. In general, the trade winds are more persistent in the summer than in the winter (frequendes average 90 and 50 percent, respectively) and stronger in the afternoon than at night At night the wind diredion becomes variable and blows out of the mountains. This difference is due to the presence of the island's two largest mountains, Mauna Kea and Mauna Loa. The island terrain influences the dimate with rainfall amounts varying with elevation and location and the effect of the persistent northeasterly snide winds. The Puna area receives between 130 inches of rain near the coastline and as much as 200 Inches of rain in the uppermost elevations surtotuxfing the fadl'dy. The annual average temperature is 23.1 degrees C, with an average dally maximum of 27.3 degrees C and the daily minimum of 21.8 degrees C (HECO 1972). On~ite meteorological data are one of the required Inputs for dispersion modeling. HELC.O began coUeding these data (irtduding wind speed and wind drrection) on February 6. 1996. The monitoring station, Sfte 033, is located approximately 1.8 Ivn west soutlwvest of the Puna Generating Station. The monitoring statlon was operated fn compliance with U.S. Fsvironmental Protection Agency (EPA) guidelines. The wind rase for Site 033 fs shown in Figure 12-1. The distribution dsplays the expected bt-modal distribr~ion and not the nornal trade wind d,ararteristics. The winds blowing from the east are primarity daytime, while the winds from the northwest are nighttime drainage winds from the higher tertain. 1.3. Existing Air Quality The Puna Generating Station ambient air and meteorological postconstrudfon monitoring program was located at a station located approximately 1.6 km west southwest of the Puna Generating Station. The monitoring station is located in the area of maximum modeled impacts from the Puna Generating Station. Therefore, the air quality data are representative of the current air quality induding the existing Puna Station. The monitoring station provided data for sulfur dioxide (SOS, particulate matter less than 10 microns in diameter (PM~o), nitrogen dioxide (NOS, carbon monoxide (CO), and ozone (O~ from January 1993 through December 1993. Table 1.3-1 shows the resulting air quality data as well as the percent of data recovery. The data collected at the monitoring station confirm that the operation of the existing Puna Generating Station does not cause an exceedance of the State Ambient Air Quality Standards (SAAQS) or the National Ambient Air Quality Standards (NAAQS). The worst air pollution episodes experienced on the Island of Hawaii are the result of volcanic eruptions. Vsibility is reduced by the presence of fine particulate resulting directly from volcanic activity and, secondarily, from forest fires caused by ensuing lava flows. In addition, there can be substantial increases in the ambient concentrations of sulfur dioxide and a number of toxic pollutants, such as heavy metals, during volcanic events. 2. Applicable Federal Regulations Emissions of air pollutants are regulated at the federal level pursuant to the Clean Air Act (CAA). The following are some of the major provisions of the CAA that potentially apply to any future expansion of the Puna Generating Station's generating capaicity: • National Ambient Air Quality Standards (NAAQS) New Source Review (NSR) - Prevention of Sign cant Deterioration (PSD) Program - Nonattainment NSR Regulations • New Source Performance Standards (NSPS) • National Emission Standards for Hazardous Air Pollutants (NESHAP) • Good Engineering Practice (GEP) Stack Height Provisions 21. (National and State Ambient Air 4uafiity? Standla~ds The EPA has established two types of NAAQS spedfying maximum acceptable pollution levels for outdoor air. The standards are designed with a margin of safety to protect the most sensitive Individuals of the population. Primary sfeutdands set limits that protect public health. Secondary standards protect public welfare. These standards must be attained in all areas that are accessible to the general public The seven criteria pollutants for which NAAQSs have been established are: sulfur dioxide (SOS, nitrogen dioxide (NOS, carbon monoxide (CO), ozone (Os), particulate matter less than 10 microns (PMro), particulate matter less than 2.5 microns (PMza) and lead (Pb). Hawaii s State Ambient Air Quality Standards (SAAQS) for sulfur dioxide and PM,o are similar to the federal NAAQS. The state has more stringent standards for carbon monoxide, ozone, and nitrogen dioxide. The state standards for other criteria pollutants are identical to the NAAQS except that the state has made no distinction between primary and secondary standards and that 2 Hawaii also has an additional standard for hydrogen sulfide (HZS). Table 2.1-1 shows the federal and state ambient air quality standards. 22 New Source Review PSD regulations (40 Code of Federal Regulations [CFR] 52.21) apply to major stationary sources located in areas meeting the NAAOS. The PSD regulations define a major stationary source as any source that belongs to a list of 28 categories that have the potential to emit 100 tons per year (TPY) or more of any pollutant regulated under the CAA, or any other source type that has the potential to emit pollutants in amounts equal to or greater than 250 TPY. The Puna Generating Station is classified as a major stationary source. If a modification to an existing major source is located in an area in compliance with the NAAOS, a PSD review is required for all pollutants that have the potential for signirficant increases in emissions because of the modification. Because the Puna area is designated either attainment or unclassifiable for all the NAAOS, a PSD review will be required for ail pollutants that show a significant increase. The PSD regulations require states to designate all geographic areas into one of three classes: • Class I applies to those areas where practically any deterioration in air quality would be significant. • Class II applies to areas where moderate, well-controlled and well-sited industrial growth would be permitted. • Class III applies where industrial areas would be allowed to experience the greatest degree of air quality deterioration. Pollutant-spedfic PSD review indudes: • Application of Best Available Control Technology (RACY) Analysis of ambient eir quality Impacts from the project (PSD Class II and ambient) Anaysis of air quality and visibility impacts on Class I areas Analysis of the Impact on things such es sods, vegetation, and visibility that are affected directly as a resuR of air emissions from the project and general commercial, residential, and other growth assodated with the project. The State of Hawaii Department of Health (DOH) has designated the Puna area as Class il. The dosest Class I area is the Volcanoes National Park, located approximately 14.4 miles southwest of the project The Class I and Class II PSD increments and the NAAQS/SAAQS for sulfur dioxide, nitrogen dioxide, PM/PM,o, and carbon monoxide are presented in Table 2.2-1. The sign cant impact levels for sulfur dioxide, nitrogen dioxide, carbon monoxide, and PM/PM,o are also presented. Hawaii's attainment status for all criteria pollutants means that the nonattainment regulations do not apply to any future expansion of the Puna Generating Station's generating capaicity:. 3 23. New Source Performance Standards The NSPS are a set of national emission standards that apply to new, mod'rfied, or reconstructed stationary source categories. One of these standards, subpart GG indudes the emission limitations that apply to a new, oil-fired combustion turbine. Spedfically, that subpart requires: • Sulfur dioxide - 0.015 percent sulfur dioxide in the exhaust gas at 15 percent oxygen, or 0.8 percent sulfur fuel by weight, and • Nitrogen oxide - 75 parts per million (PPM) in the exhaust gas at 15 percent oxygen and on a dry basis. Any future expansion of the Puna Generating Station's generating capaicity: would comply with these standards. DoH regulations (Section 11-60.1-38(b)) limit the fuel sulfur content to 0.5% by weight for fossil fuel fired power and steam generating fadlities having a power generating output in excess of 25 MW or a heat input greater than 250 MM BTU/hr. 24. National Emission Standards for Hazardous Air Pollutants The NESHAP regulations currently do not apply to the Puna Generating Station since hazardous air pollutant standards for fossil-fuel-fired power plants have not been developed by EPA. 2.5. Good Engineering Practice:Stack Height Provisions The federal guidelines for GEP stack height apply to the project. These guidelines ident'rfy design criteria acceptable to regulatory agendas to establish a method for determining the stack height that will minimize the influence of nearby structures on normal plume dispersion. 3. Applicable Hawaii Regulations In addition to the federal regulations, the State of Hawaii regulates air potludon under Hawaii Administrative Rules (HAR), Title 11, Chapters 59 end 60.1; Hawaii State Ambient Air Quality Standards (SAAQS); and Hawaii Air Pollution Control Rules, respectively. Hawaii's State Ambient Air Quality Standards (SAAQS) for sulfur dw~dde end PM,o are similar to the federal NAAQS. The state has more stringent standards for carbon monobde, omne, and nitrogen do~3de. The state standards for the other criteria pollutants ere identical to the NAAQS except that the state has made no dis8ndion between primary and secondary standards. Hawaii also has an additional standard for hydrogen su~ide (HZS). The SAAQS are shown in Table 2.1- 1. 4. Project Impacts Detailed estimates of the air quality impacts assodated with any future expansion of the Puna Generating Station's generating capaicity: would typically be calculated by conducting an air quality dispersion modeling anaysis. While that level of analysis is beyond the scope of this impact evaluation, such an analysis will be conducted for and inducted with the CSP/PSD application to be submitted to the Hawaii Department of Health. That analysis will meet the a requirements of federal and state air quality regulations. The following paragraphs describe how that modeling analysis may be performed. The potential ambient air quality impacts of any future expansion of the Puna Generating Station's generating capaidty: are determined by means of dispersion modeling. EPA-approved models will be used in the air quality analysis. The choice of appropriate dispersion modeling methods for evaluating the air quality impacts for the any future expansion of generating capadty is governed by EPA's modeling guidelines (40 CFR Part 51, Appendix W) and the topography of the site area. The area surrounding the site consists of both simple and complex terrain, i.e., the terrain- heights are below stack height in some areas and above stack height in others. Therefore, a model with the ability to perform calculations in both simple and complex terrain will be used. Two EPA-approved models, ISCST3 and ISC_RTDM, can pertorn the calculations. Either model is suitable for the air quality analysis. ISCST3 contains COMPI FXI (an EPA- approved complex tenain model) and ISC_RTDM contains RTDM which is also an EPA approved complex terain model. Both ISCST3 and ISC_RTDM implement the EPA Intermediate Terrain Guidance. An analysis of potential visibility impairment will be evaluated using the EPA guideline model VISCREEN. The computer models will be used along with the complete year of on-site meteorological data to estimate air quality in the vidnity of the power plant when the facility is operating at its maximum proposed emission rate. The modeled impact of the project will be compared with various regulatory threshold concentrations. The purpose of the modeling is to demonstrate that the operation of any proposed expansion of the HELCO Puna fadlity will not cause or contribute to a violation of any PSD increment or ambient air quality standard. The following is a list of the prindpal elements of the air quality impact assessment to be included in the CSP/PSD application: Identrfying the worst-case scenario, Determining the impact area based on worst-case operating scenario, • A PSD Class I Increment consumption analysis inducting visibility and air quality impacts, • A PSD Class II Increment consumption analysis, • NAAQS and SAAQS assessment, • Non-criteria pollutant analysis, and • Other potential air quality impacts (such as soils, vegetation, and visibll'ity). 4.1. Construction Air Emissions Construction of the any future expansion of the Puna Generating Station's generating capaidty. would produce two types of emissions: (1) exhaust from vehides and construction equipment and (2) dust generated during site excavation and equipment movement Equipment exhaust emissions would be small, localized and transient. Dust emissions would be controlled by watering the site during dry or windy periods. 5 4.2 Operational Air Emissions Although no modeling has been pertormed for any future expansion of the Puna Generating Station's generating capaicity:, recent modeling of the e>asting Puna Generating Station has been pertormed for CSP application # 0235-01. This modeling includes the impact of the existing Puna Generating Station sources. Emission rates for the existing Puna sources are shown in Table 4.2-1. The modeling analysis demonstrates that predicted concentrations for the existing Puna Generating Station are below the NAAOS and SAAQS. The modeling of the e>asting CT-3 and boiler at Puna provides a general estimate of the location and magnitude of maximum impacts that may be expelled from a new combustion turbine and boiler. The EPA guideline dispersion model ISCST3 was used to calculate ma~amum concentrations of combustion pollutants that would potentially result from the exsting Puna Generating Station. The following information was used to predict the maximum ground-level concentrations of air pollutants from the Puna Generating Station: A full year of Hilo airport meteorological data The curenUy permitted souroes of emission rates as defined in CSP application # 0235- 01,which includes CT-3 and a boiler The exsting fadiity configuration GEP analysis. The modeling analysis predicted the ma~amum ground-level concentrations for nitrogen dioxide, sulfur dioxide, PM,o, and carbon mono~ade. The modeling assessment only included sources from the Puna Generating Station. All predicted concentrations were well below the coresponding NAAQS and SAAQS. The SOZ 24hour modeling results showed the highest percent of the standard at 53.3%. Most other modeling results were less than 17% of their respective standard. CO, NO2, and annual PM,o maximum impacts were located 2 to 3 km southwest of the fadlity in complex terrain. SOZ and short term PM,o maximum impacts were located within 0.5 km of the fadlity in intermediate terrain. 4.3. impacts on Soils, Vegetation, and Visibility Federal Primary Air Quality Standards are based on protection of human health. Federal Secondary Air Quality Standards (which in most cases are no less stringent than primary standards) are based on human 'WeHare; which fndudes such considerations as impacts to vegetation, animals, visibigly, and comfort. Shx6es for the previous air permit application for the power plant (HI 90-04) did not identify any sensitive soils or vegetation in the vidnity of the plant. Therefore, since the maximum concentrations must be below the State Air Quality and Federal Secondary Air Quality Standards, the soils and vegetation would not be significantly Impacted. 5. Mitigation Measures Construction and operation of the any future expansion of the Puna Generating Station's generating capaidty. would tie approved only when state and federal regulatory authorities are satisfied that HELCO will be able to fully comply with the applicable rules, regulations, and air quality standards. Additional mitigation measures may be established by the Hawaii Department of Health (DoH) during the permitting process and may include limitations on the allowable size of the fadlity, emission control technology requirements, or spedfications of fuel properties. The s projects design, including the stack height and emission controls, will be appropriate to minimize adverse air quality impacts. 6. References Hawaii State Department of Health.

HELLO is currently operating under a special use permit for their current activities and is seeking to rezone the site. HELLO wants to redesignate the site to the State's urban district, and rewne the site to the County's general industrial designation. HELLO wattts to do this since the current use of the site is consistent with uses permitted under the general industrial designation. HELLO currently has ao plans to either increase the generating capacity at the pone Generating Station or increase the intensity of ancillary uses at the site. However, HELLO anticipates that the site's generating capacity and ancillary uses will be increased at some time in the future. No significant adverse impacts to fish and wildlife resources are expected to result from the proposed zoning change. However, the Service would like you to be aware that the Hawaiian hawk (Buteo solitarius) and Hawaiian hoary bat (Lasiurus cinereus semotus) have been sighted in the proximity of the generating station. The Service appreciates the opportunity to comment on the proposed zoning change. If you have questions regarding these comments, please contact Fish and Wildlife Biologist Elizabeth Sharpe by telephone at 808/541-3441 or by facsimile transmission at 8081541-3470.

No. P-7361 - April 27, 1998 Mr. AI Lono Lyman Senior Project Manager CH2M HII.L, Inc. 1585 Kapiolani Boulevard Suite 1420 Honolulu, Hawaii 96814 Dear Mr. Lyman: Subject: Request for Agency Comments Concerning Hawaii Electric Light Company's (1~LC0) Puna Generating Station Land Use District Boundary Amendment and Rezoning, TMK: 1-06-03: 93 (10.5 acres) We have received your letter dated March 25, 1998, requesting written comments from our agency regarding HELCO's proposed boundary amendment and rezoning for the Puna Generating Station. According to the information provided, the power generating activity was an ancillary use of a permitted sugar operation. When the sugar operations ceased, HELLO acquired a portion of the mill site and the adjoirt}ng railroad right-of-way in order to continue genetsung power. The Hawaii County Planning Commission approved HELCO's request for a Special Permit in 1988. The permit allowed HELLO to establish the electric power plant and the related improvements as the principal use of the site. In 1992, HELLO initiated setvrce with its 20.8-MW GT-3 generating unit at the Puna Generating Station. HELLO is seeking to reclassify the 10.5-acre site from the Agriculttual to the Urban District and to rezone the site from the A-20 agricultural zoning district to the County's general industrial district (MG). The Puna Generating Station site is less than one-half mile from Keaau Town, and one quarter of a mile from the closest point of the proposed Keaau Bypass Road. In 1993, three areas consisting of approximately 660 acres around the Keaau Town core were reclassified from the Agricultural District to the Urban District. Currently, the landowner, W.H. Shipman, Ltd. is developing a master plan for the 660 acres, and has begun discussions with a developer regarding residential development The surrounding land uses consist mainly of formerly cultivated sugaz cane lands, vacant lands, small agricultural operations, and homes. Most of the surrounding properties are large pazcels of land which are also owned by W.H. Shipman, Ltd. With plans for schools, housing, and other urban uses underway, HELCO's expectations that the site's generating capacity and ancillary uses will be increased at some time in the future are most likely correct. However, while the location of school facilities has been determined, the _ Mr. Al Lono Lyman Aprll 27, 1998 location of other urban uses within the reclassified 660 acres have not been finalized. Further, some agricultural operations may be relocated, with W.H. Shipman offering land. Since HELCO currently has no plans to either increase the generation capacity at the Puna Generating Station or increase the intensity of ancillary uses, the applicant should explain the need for a boundary amendment from the Agricultural to the Urban Distract at this time. According to the information provided, it is our understanding that any expansion of the site's generating capacity or ancillary uses is allowed under the current Special Permit No. 686.

We have reviewed all of the correspondence you sent relating to historic sites on the subject property, including the letter of September 21, 1988 from then Chairperson, William W. Paty Because the area has been so extensively disturbed we believe that there are no significant historic sites remaining on the subject property.

The Clean Air Branch, Department of Health has no comments on the proposed boundary amendment and rezoning, however, would like to offer the following clarifications on the air pollution control requirements: 1. The air permits are not "discretionary permits." Anew air permit or a permit amendment is required to be obtained prior to initiating construction on any plant modification that will result in an emission increase. This includes, as applicable, any increase in the generating capacity and ancillary uses at the generating station. 2. Any proposed plant modifications are required to comply with ali state and federal air requirements including the national ambient air quality standards. 3 The Puna Generating Station 7s considered a major soures .of air emissions and subject to the covered source permit provisions, Depending on the level of emission increase from a proposed modification, there are different permitting actions, each incorporating different procedural and public participation requirements. The public participation requirements range from no public participation for a minor modification to a 30-day public comment period followed by a public hearing for a significant modification triggering the federal Prevention of Significant Deterioration (PSD) review.

Permitted Use: Establishment of an Electric Power Plant and related improvements Tax Map Key 1-6-3.93 Keaau Puna Hawaii This is in response to your letter dated January 2, 1997, relating to the above-referenced Special Permit No. 686. We have reviewed our files and hereby confirm that the HELCO's Puna Generating Station situated on the subject site is located within the area designated as "Industrial" by the General Plan Land Use Pattern Guide (LUPAG) Map. Further, Special Permit No. 686 does not impose any conditions limiting the generating capacity of the power plant nor the construction of related improvements. According to the hearing transcript of the November 15, 1988, Planning Commission hearing, a representative from HELLO indicated that the existing plant then needed to be more efficient and possibly increase the number of megawatts. Therefore, we affirm that the Special Permit does allow HELLO to expand its electric power plant and related improvements on the subject property. Mr. Al Lono Lyman Page 2 February 3, 1997 Subsequent to the approval of Special Permit No. 686, plan approvals were granted by the Planning Director and building permits were issued by the Department of Public Works Building Division for the combustion turbine #3 control house, combustion turbine #3 six steel tanks, a 250-foot stack, storage building and other improvements. Please be advised that should there be any additional improvements to the generating station site, plan approvals must be secured from this department as well as approvals from other affected government agencies.
