Problems/Comments

OT029 Groundwater Zone 3 has 2 disposal areas known as North and South Bluffs with sporadic low level detections of contaminants in the groundwater, and the White Alice Communications Site (WACS) where PCBs remain in the soil between 1 and 2 mg/kg. Petroleum contaminated groundwater at or slightly above the groundwater cleanup levels has been noted at the White Alice Site; continued investigations are planned. The groundwater zones were established in areas with similar hydrological, geological, geographical, and contamination characteristics, and contain numerous Installation Restoration Program (IRP) sites within each zone. The IRP sites within Zone 3 include: LF005 South Bluff and Landfill #1; LF014 North Bluff; and OT010 White Alice Communication. A Final Record of Decision for the Bluff sites (dated April 2000) was signed by ADEC and the Air Force.

6/30/1989 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CH2M Hill stage 2 workplan to assess 4 sites: North and South Barrel Dump Sites; Naknek River; and Eskimo Creek seeps. Remedial investigation and feasibility study occur in parallel. Former Staff
6/30/1989 Update or Other Action (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). CH2M Hill QA/QC plan for various King Salmon Airport sites; the sites include the Eskimo Creek oil seep, North Barrel Dump, Naknek River seep, and the South Barrel Dump. A total of 17 sites were addressed by this QA/QC plan. Former Staff
8/29/1989 Update or Other Action (Old R:Base Action Code = SI - Site Investigation). CH2M Hill site investigation. The airport was originally constructed in the early 1940s to support the war effort. The airport was turned over to the State of Alaska in 1959. The State continues to operate the site with the Air Force as the major tenant. A White Alice site was activated in 1957. It was deactivated in 1979 and replaced with an Alascom Satellite earth terminal. Only a small portion of the site is owned by the State. The majority is on military land. In 1980, 340 military personnel resided at King Salmon Airport. The north and south barrel dump site, Eskimon Creek Seep and Naknek River seep sites were tested for over 146 constituents of concern. Of these, 39 potential contaminants of concern were identified. High concentrations of TPH were identified in shallow wells and soils at this site. Floating product (>1 foot) was identified at the Eskimo Creek Seepage Site. Lead and petroleum hydrocarbon contamination levels at this site pose a threat to fish and wildlife (page 126). No immediate environmental threat was identified at the Naknek River Seep (page 126). Both the north and south dump sites could pose a threat to fauna since the detection limits used in analyses were greater than the chronic aquatic organism toxicity. Remediation, based on stage 2 sampling, at both barrel dump sites could include: no action; restricting site access; preventing the migration of contaminants. Containment preferred remediation route. The Naknek River and Eskimo Creek seeps will receive further sampling to identify a specific remediation response. In general, based on further sampling results, the alternatives are: no action, which will not occur based on preliminary site investigation; recovery of floating product; treatment of shallow groundwater; excavation of contaminated soils; restrict site access; containment.

8/17/2022 Document, Report, or Work plan Review - other ADEC submitted responses to comments received on August 15th 2022 regarding the Draft Monitoring Well Installation, Repair, and Decommissioning Report, King Salmon Divert, Alaska Dated May 2022. Approximately 6 cubic yards of soil cutting material was generated from the monitoring well activities. The approved work plan discussed the soil cutting material getting sampled and characterized prior to disposal, however this report noted historical results were used for characterizing the soil cutting material. Using historical results for characterizing investigative-derived waste is not appropriate, especially when the historical results are for petroleum only and the potentially contaminated media could have impacts from other analytes (per-and polyfluoroalkyl substances and pesticides for example). While the Transport, Treatment, & Disposal Approval forms were submitted retroactively, it is the department’s expectation that these forms be submitted to ADEC for approval prior to the transport and disposal of contaminated media. Per 18 AAC 75.370(b) “A responsible person, owner, or operator shall obtain approval before moving or disposing of soil subject to the site cleanup rules.” ADEC approval was not obtained prior to transporting the soil cutting material offsite.

Continued groundwater and surface water sampling and land use control (LUC) inspections were recommended for all sites. The groundwater investigation at the SA039-DR16 source area, located northwest of Groundwater Zone 2, found no groundwater exceedances of 18 AAC 75.345 Table C groundwater cleanup levels for diesel range organics, residual range organics, and polycyclic aromatic hydrocarbons and site closure was recommended for the site. ADEC is tracking SA039-DR16 as a source area part of the King Salmon AS GWZ 2 SA039 (ADEC File No. 2569.38.016.10). Based on the available information, SA039-DR16 does not need further investigation at this time, and ADEC will consider the source area cleaned up. However the King Salmon AS GWZ 2 SA039 site will remain active on the database until all other source areas within SA039 are ready for closure. The report included a 2022 work plan addendum for the upcoming field investigation, monitoring and reporting activities to be conducted during the 2022 remedial action operations and LUC inspections.

Description Details
Groundwater Monitoring Residential wells near the bluffs have been sampled for potential contaminants several times since 1994. No contaminants have been detected; consequently, residential wells will no longer be sampled. Instead a more comprehensive system of sentry wells has been installed and will be sampled as delineated in the revised monitoring plan (Bristol/OASIS, 1999a). Groundwater and surface-water monitoring at the bluffs will continue on an annual basis following procedures outlined in the revised monitoring plan (Bristol/OASIS, 1999a).
