Groundwater Zone 3 (OT29). Estimated 500,000 barrels (contents unknown) and miscellaneous solid waste disposal area from the 1950s to the 1970s. Approximately 200 drums were removed in 1984, and 26,000 drums were removed in 1991. In 1997 and 1998, limited removal actions, re-contouring, and capping activities were conducted at North Barrel Bluffs. An Operation, Monitoring, and Maintenance manual has been developed for both bluff sites. A three party agreement was reached between EPA, ADEC, and the Air Force for the bluff sites and signed by the agencies in 1996. An interim action record of decision was signed in 1996, and a final record of decision was signed in 2000. The Final Record of Decision states that based on current site conditions and the successful implementation of interim remedial actions, USAF, ADEC, and USEPA have selected a plan of institutional controls (site-access and land-use restrictions), bluff inspection and maintenance, continued operation of the water-treatment system, and continued monitoring, with no further remedial action planned, as the final action for the North and South Bluff.

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.

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.

Site Visit

ADEC staff traveled to King Salmon with the new RPM for the King Salmon Air Station to tour the sites and look at the excavations that were completed during the 2009 field season. Several sites were inspected and overall the sites appeared to be secured with orange snow fencing and visqueen covering the stockpiles to prevent ponding and migration of contaminants. While in King Salmon staff attended and participated in a Restoration Advisory Board Meeting to meet with the public of King Salmon and discuss the results from the latest round of base-wide sampling and to discuss the progress of the excavations that were conducted during the summer.

ADEC approves the 'Final 2017 Five-Year Review, King Salmon Divert, Naknek Recreation Camp I, Naknek Recreation Camp II, Alaska, November 2017' in a letter dated May 15, 2018. Land Use Controls have not been fully implemented at any groundwater zones at King Salmon Divert. Recommendations include: finalizing the decision document for Zone 7, determine the extent of drinking water wells at Lake Camp (number of wells, depth of wells, and groundwater gradient), and fully implement LUCs by updating public land records for non-USAF owned properties. The next five-year review will be completed in 2022.

Document, Report, or Work plan Review - other

ADEC approved the Final 2017 Long Term Management Report for the King Salmon Divert on this date. Zone 1 recommendations include continuation of monitoring with no changes. Petroleum hydrocarbons and TCE were detected above cleanup levels in groundwater in Zone 2; recommendations include continued monitoring and updating cleanup levels in next 5 Year Review. In Zone 3, low levels of TCE and benzene were detected in the March 2018 SBTS sample, and gabions in King Salmon Creek are being pulled out of alignment; recommendations include reducing sampling at the North and South Bluffs to once every five years. In Zone 4, petroleum hydrocarbons were detected above cleanup levels in the A-aquifer but below cleanup levels in the B-aquifer; recommended that monitoring should continue due to drinking water wells and other sensitive receptors lying downgradient of this site. Monitoring will continue in Zone 5 without changes. Inspections of the Rapids Camp and Landfill were conducted in Zone 6; there were no observations of noncompliance at the landfill. Two of eight wells in Zone 7 exceeded RAO for DRO; 2015 soil samples from three LF01 locations indicated DRO contaminated soil above cleanup levels - this should be excavated and treated.

Update or Other Action

In June 2020, the Air Force submitted a Request for Cleanup Complete with Institutional Controls Determination for King Salmon Divert Sites South Bluff (LF005) and North Bluff (LF014), and Determination of Cleanup Complete for Groundwater Zone 3 (OT029), dated June 2020. Following review of the request, ADEC has determined that LF014 and GWZ3 are not eligible for closure, as the timeframe of use for these sites overlaps with possible use of Aqueous Film Forming Foam. Therefore, ADEC has requested the Air Force sample for PFAS at LF014 and GWZ3 prior to closure consideration of these sites.

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).
