NOTICE OF PROPOSED WATER POLLUTION
CONTROL PERMIT FOR AES HAWAII, INC.
NPDES PERMIT NO. HI 0021130
06-CW-PW-22
July 14, 2006
The State Department of Health (DOH), tentatively proposes to issue a National Pollutant Discharge Elimination System (NPDES) permit to discharge storm water from the AES Hawaii (Facility) to the Pacific Ocean, subject to special conditions to:
AES HAWAII, INC.
The proposed permit will expire on November 30, 2010.
AES Hawaii, Inc. is located in the Campbell Industrial Park in Ewa, Oahu, Hawaii and operates a large coal-fired cogeneration facility that simultaneously produces electrical and thermal (steam) energy. The electrical energy produced by the facility is sold to the Hawaiian Electric Company and the thermal energy is sold to the nearby Chevron Refinery. Coal used in the operation is transported to the facility from the Barbers Point Deep Draft Harbor via a covered conveyor.
Process wastewater associated with the production of electrical and thermal energy is discharged to underground injection wells. Storm water runoff associated with the bulk materials storage area is directed to retention basins with a capacity of containing a 10-year, 24-hour rainfall event. Overflows from the retention basin are discharged to the Pacific Ocean through Outfall Serial No. 002 located at: Latitude 21E17\u201956\u201DN and Longitude 158E06\u201922\u201DW. Storm water runoff from the rest of the facility is discharged to the Pacific Ocean through Outfall Serial Nos. 001 and 003 located at: Latitude 21E18\u201916\u201DN and Longitude 158E06\u201938\u201DW, and Latitude 21E17\u201924\u201D and Longitude 158E06\u201940\u201D, respectively.
RO and R1 water distribution lines from the Honouliuli Water Recycling Facility were installed within the facility to supply the Permittee and the Chevron Refinery with these types of water. If there should be pipeline failure of the distribution lines, RO and R1 waters will discharge through Outfall Serial Nos. 001, 002, and 003 at coordinates described above.
The Pacific Ocean is classified by the Department of Health as a Class A, Wet Open Coastal Water under Hawaii Administrative Rules, Section 11-54-06(b)(2)(B). The uses to be protected are all uses 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 discharge which has not received the best degree of treatment or control compatible with the criterial 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 days after the date of this notice, either in person or by mail, to:
