Problems/Comments

Soil contamination from fuel tanks. Contaminated soil left in place at Buildings 101, 111, 400 and 603. Groundwater contamination at Building 603. Living Quarters Area includes Buildings 101, 106, 107, 108, 109, 110, 111, COMSERFAC Building 200, Flight Service Station Building 400, Powerhouse Building 603, Old Tank Farm, Pump House and Fuel Dispenser. Drinking water wells are located at Buildings 106, 108, 400 and 603. Contaminated soil was transported off site to the NDB area and treated by landspreading. ClOSED SITES: Living Quarters Buildings 101, 106, 107, 108, 109, 110, Buildings 200, Building 400, Pumphouse and dispenser, were all seperated out and closed. ACTIVE SITES: Building 111, 603, are now tracked as separate sites, leaving the old tank farm as the only open sites under this facility. LTM currently happening. Remediation of the plume cannot occur until the buildings are removed. Based on HRC, groundwater contamination will be focus of future remedial actions. Mineral oil spill from upside down transformer in storage yard has not reached AST tank farm depth and will be managed when the main plume is remediated.

Action Information

Action Date	Action	Description	DEC Staff
2/23/1993	Update or Other Action	Notice of Release for the NDB Facility, Vehicle Fuel Pumps near Building 603.	Dennis Timmons
12/5/1995	Update or Other Action	Corrective Action Plan for Building 603 Approved. Quarterly and annual monitoring reports describes the extent of contamination at the site which has migrated 33 feet below the ground surface. Maximum DRO contamination in soils was 40,500 mg/kg. Free product had been detected in four of the monitoring wells with a maximum product measurement of 1.5 feet in well ADEC 3. The plan proposed an in-situ bioremediation project which utilizes oxygen via an air extraction well. The free product plume was to be recovered using automated product recovery units. Water supply wells are to be treated with carbon filtration. The department requested that after four consecutive groundwater sampling events with results below cleanup levels, that FAA collect soil form three borings. ADEC also requested a contaminant profile for Building 603.	Kent Patrick-Riley
1/10/1996	Proposed Plan	Approved groundwater sampling plan.	Dick Farnell

7/11/2001	Update or Other Action	Review of May 1999 "In Situ Remediation Systems Annual Report". The report recommends continued monitoring of groundwater levels in monitoring wells W-1, W-9, W-13, W-14, and ADEC-3, reducing groundwater sampling to annually, conversion of existing active system to intrinsic remediation systems and establishment of alternative clean up levels. ADEC requested FAA submit the latest In Situ Remediation Systems Annual Reports for Building 603.	Eileen Olson

5/15/2015	Site Characterization Workplan Approved	DEC approved the Work Plan - FAA Release Investigation and Remediation, Bettles Field FAA Station, Bettles, Alaska. This work plan includes several site characterization and removal actions which address multiple areas of concern (AOCs) at Bettles Field FAA Station, Alaska. Field activities proposed near Buildings 603/202 and the associated tank farm include a UVOST/LIF investigation to delineate a petroleum release, the collection of hydrocarbon risk calculator (HRC) contaminant and non-contaminant parameters, surface and subsurface soil sampling, the installation, development, and sampling of 6 new monitoring wells, slug testing in at least two wells, well repair for at least three existing wells, sampling of approximately 13 existing monitoring wells, water supply well decommissioning, lead-contaminated soil screening and excavation around both buildings 603 and 202, lead-based paint removal from the floor of Building 603, concrete sampling for PCBs, and sampling of a petroleum-contaminated soil stockpile near Building 603. At the LOC/DME facility, it is proposed that the LOC transformer will be removed and the concrete pad below the transformer will be sampled for PCBs. In addition, the WEF 420 Tower will be removed and several soil samples will be collected for PCB analysis from each side of the active transformer pad. Monitoring well elevations, soil sample locations, soil borings, UVOST probe locations, building locations, tanks, towers, and other significant structures will also be surveyed as part of the field activities.

12/13/2019	Document, Report, or Work plan Review - other	DEC approved the Final 2019 Groundwater Monitoring Program Report, FAA Stations in Bettles, Cape Yakataga, and St. Mary’s, AK, Dated December 2019. This report details 2019 groundwater monitoring activities at the Bettles, St. Mary’s, and Cape Yakataga FAA stations. Monitoring activities included collecting groundwater samples from existing wells at Bettles, St. Mary’s, and Cape Yakataga. Additionally, sediment samples were collected and analyzed at Cape Yakataga. One well at the Bettles site showed a cleanup level (CUL) exceedance of napthalene, but other wells exhibited no exceedances. Similarly, at the St. Mary’s site, one well exceeded the naphthalene CUL, but all other analytes were below CULs. One of the wells scheduled to be sampled at St. Mary’s was deemed unusable due to damage and subsequent low recharge. At the Cape Yakataga site, petroleum contamination remains above CULs in several wells, with contaminant concentrations increasing in some wells and decreasing in others. Several wells were not sampled due to insufficient water or the presence of free product. Additionally, several sediment samples were found to contain DDT and DDE above National Oceanic and Atmospheric Administration Screening Quick Reference Tables threshold and probable effects levels.
