LEGACY REGION 7 ALASKA

GENERAL

BACKGROUND:

The Sheep Island Boat Maintenance Facility site is located on the northeast beach of Sheep Island, in Uganik Bay, in Kodiak. A cannery, along with a boat maintenance facility, were constructed during the late 1950’s or early 1960’s. The cannery went bankrupt in 1991 and abandoned the boat maintenance facility. An inspection of the abandoned facility revealed heavily stained soil over an area roughly 500 square feet in size. Samples collected from the stained areas in August of 1996 revealed DRO up to 41,000 mg/kg and RRO up to 120,000 mg/kg. It was determined that in-situ remediation was the best option for the stained area. In 1999, after tilling the soil and adding fertilizer, two composite soil samples were collected from 0 to 6 inches below ground surface (bgs) and 6 to 12 inches bgs, respectively. The composite sample collected from 0 to 6 inches bgs exhibited levels of DRO up to 20,000 mg/kg and RRO up to 52,000 mg/kg. The composite sample collected from 6 to 12 inches bgs exhibited levels of DRO up to 11,000 mg/kg and RRO up to 28,000 mg/kg. A follow-up evaluation of the site was conducted on June 20, 2019 by BGES. The soil boring samples were taken a 1 bgs and 2 bgs at nine (9) locations of the land farm site. All samples were below the DEC level for DRO of 230 mg/kg except for two (2) samples that were at 248 mg/kg and 302 mg/kg.

BGES site visit on June 20, 2019, also documented several broken lead marine batteries on the north and south beach. Only one site was sampled for lead. The total lead concentration was 6,800 kg, which exceeded the ADEC criteria of 400 mg/kg, The sample was analyzed for TCLP to determine the leachability of lead from the soil sample. TCLP for lead was 301mg/l, which exceeds the federal hazardous waste criterion of 5 mg/l.

Subject: Former Sheep Island Boat Maintenance Facility, Sheep Island, Uganik Bay, Kodiak

Island, Alaska – Revised Site Characterization Activities Report (December 2025)

Dear Mr. McGinn, The Alaska Department of Environmental Conservation (ADEC) Contaminated Sites Program (CSP) received and reviewed the above-referenced draft report for site assessment activities and evaluation of site conditions for the United States Fish and Wildlife (USFWS) property located on Sheep Island, Uganik Bay, Kodiak Island, Alaska. During site assessment activities and evaluation, the existing landfarm was identified and investigated, including soil sampling. Site reconnaissance was also conducted in accessible areas of the island to identify any previously unidentified environmental concerns arising from former property use, aside from the beach, where marine batteries were observed.

Diesel range organic (DRO) concentrations at the landfarm were found to exceed the ADEC cleanup criterion, with the highest concentrations of 302 mg/Kg, and the soil sample collected from where several marine batteries were found on the beach exceeded the ADEC cleanup criterion, with a concentration of 6,860 mg/Kg. Site reconnaissance efforts did not identify any additional environmental concerns beyond the marine batteries on the beach. The report further outlines recommendations for further site characterization work.

The ADEC provided initial comments on a draft of this submission on January 4, 2019. A final report addressing all the ADEC’s comments was submitted on December 18, 2025, and it has been approved.

Mr. Shupe is the registered agent for a former cannery owned by

Cook Inlet Processing - Uganik, which is identified as an ADEC-listed contaminated site located in Port

O‘Brien. The former cannery in

Port O’Brien is located approximately 0.9 mile north of

Sheep Island, across the eastern arm of Uganik Bay. We received a return call from someone at Polar

Seafoods and they indicated they will request that the caretaker that stays at the former cannery, which is owned by Cook Inlet Processing, and Bill Reith (former ADEC employee), to contact us to discuss the former Sheep Island Boat

4. General

The report does not include discussion of how investigation derived waste

(IDW) was handled.

All soil cuttings removed during advancement of the shallow soil borings were returned to the locations from which they originated. A dry decontamination method was utilized to remove as much soil as possible from the sampling equipment. Then a minimal amount of decontamination water was generated to complete decontamination of the hand tools.

The decontamination water was spread out over the top of the area of contaminated soil so it could infiltrate. All miscellaneous solid waste was transported to

Anchorage for disposal as general solid waste.

Page 163 of PDF, #1 – Did an ADEC CS approved laboratory receive and perform all of the submitted sample analysis? The question was answered

“No,” but no explanation is provided in the checklist or report text.

This was an error on the checklist.

The question in the checklist should have been marked as “yes”. A revised checklist was attached to the revised copy of the report.

SGS was the laboratory utilized for this project and they are an

ADECCS

approved laboratory. A copy of their accreditation was attached to the approved work plan for this project.
