PEPEEKEO, ISLAND OF HAWAII
NPDES PERMIT NO. HI 0020770
DOCKET NO. HI 0020770
November 17, 2016
The Department of Health (DOH) tentatively proposes to reissue a National Pollutant Discharge Elimination System (NPDES) permit to discharge secondary treated wastewaters to receiving State waters, subject to special conditions to:
COUNTY OF HAWAII
DEPARTMENT OF ENVIRONMENTAL MANAGEMENT
345 KEKUANAOA STREET
HILO, HAWAII 96720
The proposed permit for the discharge will expire five (5) years from the effective date.
The Kulaimano Wastewater Treatment Plant (facility) is located at 28-214 Waimaaua Road, in Pepeekeo, TMK:(3) 2-8-007:075. The facility serves a population of approximately 1,800 and was designed to provide secondary treatment to sanitary wastewater at a flow of 0.50 million gallons per day. Secondary treatment at the facility consists of comminution, aerated grit chamber extended aeration secondary treatment, secondary gravity clarification, chlorine disinfection, and sulfur dioxide dechlorination. Sludge treatment consists of aerobic digestion, gravity thickening, dewatering by centrifuge, and disposal to landfill. Secondary treated domestic wastewater is discharged at the shoreline into the Pacific Ocean, approximately 500 to 700 feet north of the mouth of Waimaauou Stream, through Outfall Serial No. 001 at coordinates: Latitude 19º50’01″N and Longitude 155º05’01″W (NAD 83). The outfall is located approximately 20 feet above the foot of a rocky cliff face.
The receiving water, the Pacific Ocean, is classified by the DOH as Class A, Wet Open Coastal Waters under Hawaii Administrative Rules, Section 11-54-6(b)(2)(B). It is the objective of Class A waters that their use for recreational purposes and aesthetic enjoyment be protected. Any other use shall be permitted as long as it is compatible with the protection and propagation of fish, shellfish, and wildlife, and with recreation in and on these waters. These waters shall not act as receiving waters for any discharges which have not received the best degree of treatment or control compatible with the criteria established for this class.
Persons wishing to comment upon or object to the proposed NPDES permit or to request a public hearing, should submit their comments or requests in writing no later than 30 calendar days after the date of this notice, either in person or by mail, to:
