UPD; An ADEC letter was sent giving approval to landspread contaminated soils w/o a liner or cover as part of a research project that is being conducted to see if any leachate generated actually adversely affects underlying native soils. |

ADEC staff recieved an electronic copy of the Draft Work Plan for Remedial Investigation Work at King Salmon Airport due to the 2009 planned Airport Improvement Project. There is historical data that suggests that contaminated media may be encountered during the excavation and other clearing activities in the preliminary efforts fo the Airport Improvement Project. This plan outlines the investigation techniques used to delineate the extent of contamination and guide the drafting of a Corrective Action Plan. |

ADEC met with the FAA and their consultant today to discuss the comments on the Corerctive Action Plan for summer 2009 work at King Salmon. The Corrective Action Plan was approved to be finalized based on the responses to comments that were provided during the meeting. Most of the discussion was concerning the need for propper environmental oversight at the site of the on-going excavation and the approporiate action levels for field screening during the excavation. These issues adn more were resoloved and a letter was issued from this office to the FAA approving the finalization of the Corrective Action Plan. |

Contaminted Sites Staff recieved a copy of the Federal Aviation Administration's King Salmon Release Investigation Work Plan dated November 2011. The Plan details the FAA's Release Investigation objectives for several areas of concern including the New Housing Unit 28 (UST 3-H-38); Current Shop Building 600 (UST 3-J-1); Storage Building 614; Former Utility Building; Former Shop Building; Shop Building; Former Prime Power Building; Existing Storage Building 300; Former COMSERFAC Building 303; Former Prime Power/Carpenter Shop Engine Stands Building 30; and the Former Living Quarters Buildings 102, 103, 106 and 107. The FAA is proposing the use of the Hydrocarbon Risk Calculator to evaluate the need to actively remediate these sites.

Contaminated Sites Staff submitted a letter to the Remedial Project Manager with the FAA regarding the work plan for the Release Investigation at several sites at King Salmon. ADEC was concerned about some of the sites associated with the UIC closures through the EPA and wanted to make sure that the investigations could include those sites as well. |

Submit comments on the Draft FAA-King Salmon Release Investigation report. The report details the investigation at 15 locations within the FAA Facility. Investigation data is evaluated using the HRC. The majority of the locations had low level hydrocarbon contamination and are eligible for CCIC. Follow-up investigation is required at three locations. |

Reviewed the Revised Draft Final Work Plan – Release Investigation King Salmon FAA Station, dated May 2017 for the FAA King Salmon sites. The objective of the proposed work is to further evaluate two areas of concern (New Housing Area Unit 38 and Shop Building 600), to perform excavation at the Former COMSERFAC Building 303, and to perform other closure related activities as recommended in the 2012 RI. |

Reviewed the Draft Release Investigation Report, dated March 2018 for the FAA King Salmon sites. The 2017 RI documents the work completed at the New Housing Unit 38, former Building 200, Shop Building 600, and the former Building 303.
(1) New Housing Unit 38: Four soil borings were advanced at the New Housing Unit 38 AOC to further delineate the extent of contamination. One sample was collected from each boring within the smear zone, and at an approximate depth of 23 to 25 feet below ground surface (bgs). Water samples were collected from four wells in the vicinity of the AOC. All soil and water results were below applicable cleanup levels; though it should be noted that a petroleum odor was noted in Well MWH2, which has historically contained measurable product. Well MWH2 is not a plume boundary well. Section 5 (Recommendations) indicates that this AOC should be evaluated for a cleanup complete determination.
(2) Former Building 200:
Four soil samples were collected from three soil borings in an effort to further characterize potential contamination related to an unknown LIF response, identified during the 2012 RI. All sample results were below applicable cleanup levels. Section 5 (Recommendations) indicates that this AOC should be evaluated for a cleanup complete determination.
(3) Former Building 303:
An additional 32.42 tons of petroleum contaminated soil was removed from this site. During the excavation, an unregistered 500-gallon single walled steel UST and associated fuel piping was encountered. The UST and piping were removed to facilitate additional cleanup. Confirmation soil samples were collected from the base and sidewalls of the excavation. All soil results, except for DRO and 1-methylnapthalene, were below applicable cleanup levels. Concentrations of DRO ranged from 0.05 mg/kg to 6,700 mg/kg, which exceeds the Method Two Migration-to-Groundwater (MTG) cleanup levels but is less than the risk based inhalation and ingestion cleanup levels. Water samples were collected from 3 monitoring wells in the vicinity of the site (MW-04, MW-05, and MP-E1). Well MW-05 was the only well to exhibit contaminants (DRO and PAHs) above Table C groundwater cleanup levels. Section 5 (Recommendations) indicates that this should be evaluated for a cleanup complete with institutional controls (IC) determination. The IC would be to restrict drinking water use. That or additional monitoring could be completed.
(4) Shop Building 600:
Twenty-nine UVOST probes were advanced at the Shop Building 600 AOC to further delineate the west and south plume boundary. Eight confirmation soil samples, not including duplicates, were collected during the investigation to correlate UVOST results. Four boreholes were completed as groundwater monitoring wells (MW101 through MW104). Water samples were collected from the four new wells and three existing wells in the vicinity of the site. Results indicate that the extent of contamination is generally well defined, except for one location to the southwest of the site, where continued investigation could not be completed because the contamination extends onto private property. Section 5 (Recommendations) states that continued monitoring should be completed to determine a stable and/or decreasing trend.
(5) Other Completed Activities:
Other activities completed in 2017 included decommissioning 13 monitoring wells across various AOCs, decommissioning a former biocell at Shop Building 600, removing all infrastructure related the SVE system at former Building 614, and completing a site-wide groundwater elevation survey to determine groundwater flow direction (flows generally west towards the river).
ADEC had various comments on the report (see file) and requested a revised version by July 1, 2018.
