WASTEWATER SYSTEMS
PUBLIC NOTICE OF
VARIANCE APPLICATION NO. WW 294
DOCKET NO. 08 - VW W - 23
Pursuant to H.R.S: Section 342D-7(i), Hawaii Revised Statutes, the State
Department of Health (DOH) seeks written comments from interested persons
regarding the following. Mr. Mitchell Kawamura of the Hawaii Public Housing Authority
(HPHA), 1002 North School Street, Honolulu, Oahu has applied for a variance for the
maximum of five (5) years as stated in the variance application from Hawaii
Administrative Rules (HAR) Section 11-62-03 Definitions state "Individual wastewater
system means a facility which is designed to receive and dispose of no more than 1000
gallons per day of domestic wastewater. Individual wastewater systems may involve
treatment processes and include, but are not limited to, septic tanks and household
aerobic units with disposal system and cesspools. Each individual wastewater system
shall be an independent system and shall have all of its plumbing, treatment (if any),
and disposal components separate from any other wastewater systems." and Section
11-62-31.1(a)(1)(D) ""General requirements for individual wastewater systems.
Individual wastewater systems may be used as a temporary on-site means of
wastewater disposal in lieu of wastewater treatment works under the following
conditions: Developments involving dwellings. The total wastewater flow into one
individual wastewater system shall not exceed one thousand gallons, and one individual
wastewater system shall not serve more than five bedrooms, whether they are in one
dwelling unit or two."
Mr. Ronald Layaoen, Project Engineer, Okahara & Associates, Inc., 200 Kohola
Street, Hilo, Hawaii is the individual authorized to act for the applicant. The applicant
has requested the variance for HAR 11-62-31.1(a)(1)(D): The Nani O'Puna Housing
Facility consists of 1-bedroom, 2-bedroom and 3-bedroom dwelling units, a laundry
facility and a facility manager's office contained in eight (8) separate building structures.
There are two (2) Large Capacity Cesspools located on the property which serve the 8
buildings. Each of the cesspools are proposed to be upgraded with the addition of
septic tanks with conversion of each of the cesspools for use as seepage pits for
effluent disposal. The buildings are located at 15-2914 Kauhale St., Pahoa, HI TMK (3)
1-5-002: 023.
The applicant has made the following comments.
1. Each of the four (4) proposed individual wastewater systems (IWSs)
would receive more than 1000 gpd of wastewater. Wastewater flows of
3,300 gpd, 4,000 gpd, 5,600 gpd, and 2,400 gpd are estimated to be
generated, so each IWS would not comply with HAR Section 11-62-03.
The variance is requested for the four (4) proposed IWSs whose
estimated flows will each exceed 1000 gallons per day.
2. The existing large capacity cesspool(s) must be closed and replaced with
a new treatment individual wastewater system by April 5, 2005 to comply
with federal requirements.
3. The facility has been in operation for 32 years in this location using the
existing cesspool. The installation of a wastewater treatment plant in lieu
of a septic system will not be possible due to space restrictions and may
force the owner to abandon the business operation.
4. The applicant believes this variance request is in the public interest
because the LCC will be upgraded to an IWS (septic system). The IWS
plans will be designed by an engineer and will be submitted to DOH for
review and approval. The new IWS will provide a better wastewater
treatment system compared to the existing LCC. Therefore, impact to the
environment will be minimized.
5. , The existing LCC will be upgraded to an IWS (septic system). The IWS
will provide a better treatment system prior to effluent disposal. The IWS
will be designed and constructed to meet the Department of Health
standards. The impact to the environment will be minimized compared to
the current wastewater disposal.
6. The proposed treatment individual wastewater systems will provide
greater protection than the large capacity cesspools. The proposed IWS
is an improvement to the existing cesspool in terms of wastewater
treatment. The septic tank will provide pretreatment and sludge removal
prior to effluent disposal.
7. The existing location of the facility is severely restrictive. There is simply
no space to construct a wastewater treatment plant.
8. The variance is requested for the maximum of five (5) years, The Nani
O'Puna Housing Facility is located in the eastern portion of the Island of
Hawaii, in the town of Pahoa, within the Puna District. Hawaii County
currently does not have a public wastewater system in the vicinity of the
project site.
DI
Thus, the proposed four (4) IWSs will be in service for longer than the
maximum 5 years under which the requested variance would be in effect
for. It is requested that a variance be issued for five (5) year's with
automatic renewal for either the life of the facility or at such time that
Hawaii County installs a public wastewater system that is reasonably
accessible from the project site.
Design criteria, project vicinity site map and overall site plan have been attached
this application for variance but can not be shown here. If you would like to review
complete application, please call or write to the Wastewater Branch, 9j19 Ala Moana
ulevard, Room 309, Honolulu, Hawaii 96814-4920, telephone (808) 586-4294 and/or
(808) 586-4300 to obtain a facsimile. DOH will consider all written comments
:eived within thirty days of this notice. If warranted, DOH may hold a public hearing
the variance application, after receipt of separate related documents and written
nment, if any.

greater ongoing maintenance cost. 1 (owner) may be forced to close my existing
business and lay off my employees.
(2) The granting of the variance will not substantially endanger human health or safety.
[/] The existing LCC will be upgraded to an IWS (septic system). The IWS will
provide a better treatment system prior to effluent disposal. The IWS will be
designed and constructed to meet the Department of Health standards. The
impact to the environment will be minimized compared to the current wastewater
disposal.
