DEC Contact: Anne Weaver, 907-269-7483, anne.weaver@alaska.gov Review Period: November 2, 2026 through November 17, 2026 11:59 pm AKST Permit: AK0049786 – Westward Seafoods Captains Bay Facility Proposed Permit Coverage: DEC proposes to reissue APDES permit AK0049786 for the Westward Seafoods Captains Bay Facility. Description of Discharges: Westward Seafoods owns, operates, and maintains the facility, which conducts seafood processing and seafood meal reduction. The facility is located in the City of Unalaska, Alaska on Captains Bay. Processing wastes (i.e., heads, offal, unusable tissue parts) are flumed to dewatering conveyors where they are transported to the meal plant for reduction to fish meal, a marketable secondary product. Water used in bailing, butchering, processing, and fluming is collected before final discharge and passed through a 0.5-millimeter (mm) screen to recover residual tissue pieces. Screened wastewater is discharged without further treatment through Outfall 001A. In some cases, product is recovered from wastewater prior to screening, such as recovering tissue from surimi wash water using centrifuge decanters before the wash water is sent to the screens. Screened solids and unusable seafood parts are sent to the meal reduction plant. Fish meal processing produces a stream of noncontact saltwater used in evaporation machinery and to scrub dryer vapors from the meal dryers. This wastewater is discharged from Outfall 002A, along with cooling water from electricity generation and refrigeration compressors. A second fish meal wastestream contains stickwater (fish tissue liquids removed in the dehydration process) along with impure condensate from the evaporator, liquid discharges from conveyor machinery, clean-up wash water, and machinery cooling water. Stickwater is typically discharged by vessel July through September and discharged from Outfall 001A October through June. A skimmer was installed in 2014, and it skims fish oil from stickwater prior to discharge. Outfall 001A terminates 1,200 feet from the facility in a multi-port diffuser north of the rocky reef Bailey’s Ledge, at a depth of -61 ft mean lower low water (MLLW) above substrate at -83 ft MLLW but in close proximity to depths extending to -200 ft MLLW. Outfall 002A terminates at -3 ft MLLW, under the facility dock. There is a 200-foot x 253-foot mixing zone around the Outfall 001A diffuser for temperature, color, turbidity, residues, dissolved oxygen, sediment, and total ammonia. There is also an authorized 2.0-acre zone of deposit for residues on the seafloor. There is a 100-foot radius mixing zone for temperature, total ammonia, arsenic, and zinc around Outfall 002A.
