Site Characterization Workplan Approved |
CSRP staff reviewed and approved with conditions FAA's "King Salmon Final Pre-Field Planning Document, Release Investigation Plan and Health and Safety Plan." The plan is limited to two areas of the FAA Station - the Former Quarters Area and the Housing Unit Area - and proposes additional investigation of soil and groundwater contamination discovered during the fall 1998 removal of 19 underground storage tanks and contaminated soil. Where encountered, groundwater was present at 4.5 to 18 below the ground surface. Groundwater contamination was evident in six excavations where groundwater was encountered. There are six drinking water wells at the King Salmon FAA Station within ¼ mile of the Former Quarters Area. Department comments included noting that regulations require the removal of free produce on groundwater; aromatic and aliphatic methods have yet to be approved, so that sample results for those analyses are not acceptable for site closure; three drinking water wells which are slated for 1999 decommissioning should be sampled before being decommissioned; soil borings and monitoring wells should be moved closer to, or hydrologically downgradient from source areas for releases; and the community should be notified of the planned work. |

Update or Other Action |
All work performed for the Federal Aviation Administration (FAA) requires completion and approval of a Project Environmental and Occupational Safety and Health Worksheet (EOSH Worksheet). The EOSH Worksheet is a tool that allows project managers to identify potential hazards and contamination, take appropriate measures to avoid hazards and manage contamination appropriately, to minimize environmental impacts, determine whether environmental assessment is required prior to beginning work, and to minimize fines and/or penalties associated with non-compliance with federal and state regulations. It also acts a mechanism to identify when outside agency permits are necessary. Specific portions of the EOSH Worksheet address: the presence/absence of endangered species, activities conducted in wetlands or anadromous streams, whether work will occur on a contaminated site or involve activities associated with fuel tanks, fuel distribution lines, oil-containing transformers, groundwater monitoring wells, floor drains, and generation and handling of hazardous waste. To ensure all issues are appropriately considered, the worksheet is to be reviewed after each phase of project development and implemenation. This form is to be kept with project progress documents throughout the project.

Approved the final injection well closure report documenting the permanent closure of floor drains at Building 201, Building 414, and Building 600. Building 201 had a floor drain and a vehicle wash pad drain that discharged to two separate systems. The floor drain is connected to the sanitary sewer system. The outfall pipe was plugged and the floor drain sump filled with clean material then capped with concrete. No samples were collected. The vehicle wash pad drain was connected to an outfall pipe that discharged to a buried septic tank. The outfall pipe was plugged and the drain filled with clean material then capped with concrete. Results from a sample collected at the septic tank show diesel range organics above the cleanup level. Building 414 had one floor drain with an outfall pipe to a dry well. The floor drain was decommissioned at an earlier date. Results from a sample collected from the bottom of the dry well are below the cleanup level. Building 600 had two floor drains that discharged to a septic tank, which drained to a leach field. The floor drains were decommissioned at an earlier date. Results from a sample collected from the leach field are below the cleanup levels. |

The ADEC Contaminated Site Program approved the Work Plan for POL Water Release Investigation at the FAA King Salmon Station, Alaska. The objective of the work plan was to characterize potential impacts to the accidental release of approximately 200 gallons of POL-contaminated water that had been temporarily stored in a tanker between Buildings 600 and 614. The POL-contaminated water had been generated from a buried culvert at a motor vehicle waste disposal well that was emptied as part of a remediation project performed by Bethel Services in the fall of 2012. Analytical results from 2012 indicated that the water that was release had contained concentrations of DRO and VOC analytes above the ADEC groundwater cleanup levels. |

The ADEC Contaminated Site Program approved the POL Water Release Investigation Report at the FAA King Salmon Station, Alaska. The field investigation included advancing hand borings and one temporary well point; and collecting soil and groundwater samples in the vicinity of the point of POL-contaminated water release. The analytical results from the soil and groundwater samples did not exceed applicable ADEC cleanup levels, with the exception of one soil sample that contained a DRO concentration (372 mg/kg) above the ADEC Method Two cleanup level (250 mg/kg). The location of the POL-contaminated water release is between the previously documented hydrocarbon plumes near Buildings 600 and 614, and the DRO concentration detected in the soil is consistent with DRO concentrations previously detected at the adjacent sites. Based on the 2012 FAA investigation and risk analysis at these sites, the DRO concentrations do not pose an unacceptable risk to human health or the environment. ADEC is not requiring additional investigation of this POL-contaminated water release. |

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. |

Reviewed a letter titled "Sample Bias in Samples from Final Investigation Report", dated September 18, 2018. The letter notes that after the report was approved by ADEC and finalized, FAA received communication from the testing laboratory, TestAmerica that they had discovered an error in their reporting which affected some of the samples collected during the 2017 Release Investigation. The samples affected were the GRO/BTEX from New Housing Unit 38 and GRO/BTEX from seven samples collected at Building 600. The revised results do not change any result from below the ADEC CUL to above the ADEC CUL. The revised results do not change the conclusions in the Final Release Investigation Report. See file for letter. |

Reviewed the December 2018 report titled: Directional Finder Decommissioning and Remedial Action for the Federal Aviation Administration (FAA) King Salmon sites. Roughly 6.5 tons of lead impacted soils were removed from around the Directional Finder (DF) building prior to demolition. Confirmation soil samples collected from the base of the excavation confirmed lead remaining up to 44 mg/kg, which is substantially below the cleanup level of 400 mg/kg, as outlined in 18 AAC 75.341(c) Table B1. Following excavation, the DF building and associated components were demolished, and the entire area was backfilled to grade and compacted. |
