Problems/Comments

Historical spills and operational practices at Lake Camp led to contamination of the soil and groundwater with petroleum based products, specifically diesel-range organics (DRO). Numerous environmental investigations have been performed to evaluate contamination at Lake Camp. RI field activities were performed in 1994 (report date 1995) to evaluate the nature and extent of contamination in the soils, groundwater, surface water, and sediments. A FS was completed in 1999 to identify possible remedial alternatives. A monitored natural attenuation study was completed in 1998 (report date of 2000), and a limited field investigation was performed in 2000 (report date of 2001) to further delineate the extent of soil and groundwater contamination at the former vehicle maintenance facility (SS004) and former generator pad (SS005). The draft Record of Decision is at PACAF and Air Staff for review and approval. Remedial Action Objectives for SS005: soil excavation and biocell treatment, and monitored natural attenuation of groundwater. Remedial Action Objectives for SS005 and SS004: a) Reduce concentrations of contaminants of concern in soil and groundwater to meet cleanup levels. b) Prevent or minimize direct exposure to contaminants of concern (DRO) in groundwater during the cleanup process. In order to achieve the RAOs, USAF will implement the remedy outlined below. There is no surface water present at these sites. 1) Soil: Soil within the former generator pad (SS005) and former vehicle maintenance facility (SS004) that is contaminated with DRO above the cleanup level will be removed. The removed soil will be transported to the KSAS facility biocells for treatment to cleanup levels appropriate for the final disposition area within KSAS. Removal areas will be backfilled with clean soil and the disturbed areas revegetated. An estimated 800 to 1,800 cubic yards of soil require removal and treatment. Excavation confirmation sampling will be performed to verify that all of the soil above cleanup levels is removed. Confirmation sampling will include DRO and polyaromatic hydrocarbons (PAHs). The following analytes will be included in the PAH analysis: acenaphthene, anthracene, benzo(a)pyrene, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, dibenzo(a,h)anthracene, fluorene, indeno(1,2,3-cd)pyrene, naphthalene, and pyrene. DRO and all PAHs must meet tabulated cleanup levels provided in 18 AAC 75, Tables B1 and B2. 2) Groundwater: MNA will address groundwater contamination. The protectiveness of MNA will be assured by sampling on an annual basis approximately eight groundwater monitoring wells for DRO and MNA parameters. During the first year, samples will also be collected for dissolved lead analysis to determine whether lead should be considered a contaminant of concern. Monitoring will be performed consistent with a comprehensive monitoring plan to be developed by USAF with ADEC input. The monitoring program will be consistent with the technical requirements set forth in state of Alaska regulations and will be designed to address the RAOs outlined in this ROD. The number and frequency of monitoring wells sampled may be modified when sufficient data have been collected to establish trends. Unless monitoring indicates that cleanup levels have been attained within five years of implementing annual groundwater monitoring, groundwater modeling will be performed at a frequency of no less than AF point of contact: Charley Peyton, Project Manager, 611th CES/CEV 10471 20th Street Suite 338, Elmendorf AFB, AK 99506-2270; Telephone 907-552-9765.

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.
