Darrow, Deputy Planning Director FROM: Dean D. Uyeno, Acting Deputy Director C' '''''t---- Commission on Water Resource Management SUBJECT: Special Management Area Use Permit Application (PL-SMA-2024-000051) FILE NO.: RFD.6236.8 TMK NO.: (3)6-9-006:016 Thank you for the opportunity to review the subject document. The Commission on Water Resource Management(CWRM)is the agency responsible for administering the State Water Code (Code). Under the Code, all waters of the State are held in trust for the benefit of the citizens of the State, therefore all water use is subject to legally protected water rights. CWRM strongly promotes the efficient use of Hawaii's water resources through conservation measures and appropriate resource management. For more information, please refer to the State Water Code, Chapter 174C, Hawaii Revised Statutes, and Hawaii Administrative Rules, Chapters 13-167 to 13-171. These documents are available via the Internet at http://dlnr.hawaii.gov/cwrm. Our comments related to water resources are checked off below. ❑ 1. We recommend coordination with the county to incorporate this project into the county's Water Use and Development Plan. Please contact the respective Planning Department and/or Department of Water Supply for further information. ❑ 2. We recommend coordination with the Engineering Division of the State Department of Land and Natural Resources to incorporate this project into the State Water Projects Plan. ❑ 3. We recommend coordination with the Hawaii Department of Agriculture (HDOA)to incorporate the reclassification of agricultural zoned land and the redistribution of agricultural resources into the State's Agricultural Water Use and Development Plan (AWUDP). Please contact the HDOA for more information. ❑ 4. We recommend that water efficient fixtures be installed and water efficient practices implemented throughout the development to reduce the increased demand on the area's freshwater resources. Reducing the water usage of a home or building may earn credit towards Leadership in Energy and Environmental Design (LEED)certification. More information on LEED certification is available at http://www.usgbc.org/leed. A listing of fixtures certified by the EAP as having high water efficiency can be found at http://www.epa.gov/watersense. X❑ 5. We recommend the use of best management practices (BMP)for stormwater management to minimize the impact of the project to the existing area's hydrology while maintaining on-site infiltration and preventing polluted runoff from storm events. Stormwater management BMPs may earn credit toward LEED certification. More information on stormwater BMPs can be found at http://planning.hawaii.gov/czm/initiatives/low-impact-development/ ❑ 6. We recommend the use of alternative water sources,wherever practicable. ❑ 7. We recommend participating in the Hawaii Green Business Program, that assists and recognizes businesses that strive to operate in an environmentally and socially responsible manner. The program description can be found online at http://energy.hawaii.gov/green-business-program. ri8. We recommend adopting landscape irrigation conservation best management practices endorsed by the Landscape Industry Council of Hawaii. These practices can be found online at http://www.hawaiiscape.com/wp-content/uploads/2013/04/LICH_I rrigation_Conservation_BM Ps.pdf. Duane Kanuha Page 2 April 3, 2024 E19. There may be the potential for ground or surface water degradation/contamination and recommend that approvals for this project be conditioned upon a review by the State Department of Health and the developer's acceptance of any resulting requirements related to water quality. 10. The proposed water supply source for the project is located in a designated water management area, and a Water Use Permit is required prior to use of water. The Water Use Permit may be conditioned on the requirement to use dual line water supply systems for new industrial and commercial developments. • 11. The Hawaii Water Plan is directed toward the achievement of the utilization of reclaimed water for uses other than drinking and for potable water needs in one hundred per cent of State and County facilities by December 31, 2045 (§174C-31(g)(6), Hawaii Revised Statutes). We strongly recommend that this project consider using reclaimed water for its non-potable water needs, such as irrigation. Reclaimed water may include, but is not limited to, recycled wastewater,gray water, and captured rainwater/stormwater. Please contact the Hawai'i Department of Health, Wastewater Branch, for more information on their reuse guidelines and the availability of reclaimed water in the project area. • 12. A Well Construction Permit(s)is (are)are required before the commencement of any well construction work. • 13. A Pump Installation Permit(s) is (are) required before ground water is developed as a source of supply for the project. L I 14. There is (are)well(s)located on or adjacent to this project. If wells are not planned to be used and will be affected by any new construction, they must be properly abandoned and sealed. A permit for well abandonment must be obtained. ❑ 15. Ground-water withdrawals from this project may affect streamflows,which may require an instream flow standard amendment. ❑ 16. A Stream Channel Alteration Permit(s) is (are) required before any alteration can be made to the bed and/or banks of a steam channel. • 17. A Stream Diversion Works Permit(s) is (are)required before any stream diversion works is constructed or altered. • 18. A Petition to Amend the Interim Instream Flow Standard is required for any new or expanded diversion(s)of surface water. pi19. The planned source of water for this project has not been identified in this report. Therefore,we cannot determine what permits or petitions are required from our office, or whether there are potential impacts to water resources. ❑ OTHER: If you have any questions, please contact Ryan Imata of the Regulation Branch at(808)587-0225 or Katie Roth of the Planning Branch (808)587-0216.
