WATER POLLUTION CONTROL PERMIT FOR
SUNRISE CAPITAL, INC.
KEKAHA, ISLAND OF KAUAI
NPDES PERMIT NO. HI 0021654
DOCKET NO. HI 0021654
October 19, 2022
The Hawaii Department of Health (DOH), Clean Water Branch (CWB) tentatively recommends to the Director of Health (Director) to renew a National Pollutant Discharge Elimination System (NPDES) permit that regulates and imposes water pollution control requirements on the discharge of shrimp pond circulation wastewater and treated shrimp farm production process wastewater from its shrimp farm facility, to receiving State waters, subject to special conditions to:
SUNRISE CAPITAL, INC.
A permit for such discharge will expire five (5) years from the date of issuance.
The draft NPDES permit was revised based on comments resulting from the previous public notice published on September 29, 2021.
Sunrise Capital, Inc. owns and operates a shrimp farm located at 6526 Kaumualii Highway, Kekaha, Island of Kauai, Hawaii and produces 730,000 pounds of whiteleg shrimp (Litopenaeus vannamei) annually. The facility consists of
40 one-acre production ponds, 8 1/2-acre nursery ponds and 24 raceways supplied by four brackish land-based wells. Each pond at the facility is lined and includes a bottom drain system to periodically remove settled matter and a skimmer system to remove floating material. Each shrimp production pond has a volume of 1.3 million gallons, and a turnover rate of 25-40% per day, amounting to a continuous flow rate of 230 – 360 gallons per minute (gpm) per pond. When all ponds are operating, the maximum discharge rate from the ponds is 20 million gallons per day (MGD), although for the past five years, the average discharge rate is under 5.0 MGD. The shrimp pond circulation water and the pond drainage system water are sent to one of two sedimentation/conveyance canals running the length of the facility prior to discharging into a canal (“Suez Canal”).
The receiving waters, the “Suez Canal,” is an undesignated Class 2 inland receiving water. The objective of Class 2 waters is to protect their use for recreational purposes, the support and propagation of aquatic life, agricultural and industrial water supplies, shipping, and navigation.
Persons wishing to comment upon or object to the draft 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 through e-mail at: email@example.com or by mail at 2827 Waimano Home Road, Room 225, Pearl City, Hawaii 96782.
