Problems/Comments

Last Updated: November 6, 2017 The Fire Protection Training Area (FPTA; Site FT001) is located at the east end of the Former Galena Forward Operating Location (FOL), north of the runway overrun. Soil and groundwater investigations were conducted at the site between 1986 - 2013. Site FT001 is contaminated with multiple petroleum-related compounds, trichloroethene (TCE), perfluorooctanoic acid (PFOA), and perfluorooctane sulfonic acid (PFOS). Contamination in soil and groundwater is attributed to the use of up to 28,000 gallons of fuel, annually, for fire training exercises conducted from the late 1950s through 1985. Contamination is also attributed to spills and leaks from drums that may have been stored around the edge of the FPTA circle. Fire extinguishing agents used at Site FT001 included protein foam, chlorobromomethane, dry chemical, halon, and aqueous film forming foam (AFFF). The Interim Record of Decision (ROD) for Site FT001 addresses cleanup of petroleum compounds and TCE. Proposed remedies include bioventing, soil-vapor extraction (SVE), natural attenuation, and land use controls (LUC) to mitigate potential exposures until Cleanup Complete is achieved. PFOA and PFOS are considered “emerging contaminants,” and the Air Force is managing the evaluation of these compounds under a separate program. As such, the Interim ROD for Site FT001 does not address PFOA and PFOS contamination in soil or groundwater. As of November 6, 2017, the Interim ROD is pending approval.

Action Information

Action Date Action Description DEC Staff
8/29/1995 Update or Other Action (Old R:Base Action Code = RI - Remedial Investigation). Action date used is the date of the Air Force Relative Risk Evaluation Worksheet, which indicates the site is in the RI phase. No Longer Assigned
2/21/1997 Site Added to Database Site added by Shannon and Wilson. See also Reckey 198831X127201. S&W
1/29/2003 Update or Other Action See the action list in Galena AFS - all sites for overall sites activities. The Air Force plans to install an additional monitoring well at this site in summer 2003. Monitoring will be completed to determine if the g.w. meets cleanup levels and if there is potential for migration to the Yukon. Ann Farris
9/17/2003 Update or Other Action Staff received the Draft Remedial Investigation/Feasibility Study Work Plan for Galena Airport. Staff has begun review of the document. A comment resolution/technical project team meeting is scheduled October 2-3rd in Anchorage. This work plan is intended to address the many outstanding site characterization issues that were raised by Louden Tribal Council, the Environmental Protection Agency, and ADEC as well as the Remedial Process Optimization Evaluation completed in 2002. Ann Farris
1/22/2004 Meeting or Teleconference Held Staff attended the 7th Galena Technical Project Team Meeting on January 12 through 15th. We discussed most of the contaminated sites at the Galena Air Force Station and the Campion Radio Relay Station. We evaluated the adequacy of the historical site characterization, the need for further characterization, possible remedial options, the adequacy of exiting remediation systems, and the need for a risk assessment. Of the 23 sites reviewed at the meeting, 5 were already determined to be closed by ADEC, 5 are believed to not need any further characterization or remediation. The remaining 13 need additional investigation or remediation of some type. Additionally, there are a few sites that were not covered during this meeting that will still need to be reviewed. Fire Training Area - The site is probably characterized well enough, but there is still question about the southern extent of contamination and the groundwater flow regime in this area. Decision to complete groundwater monitoring under the 2004 Remedial Investigation (RI) and cap/reseed the fire training pit so no ponding occurs. Institutional controls (ICs) will need to be established in the decision document. Ann Farris
4/19/2004 Meeting or Teleconference Held Staff participated in the 9th Galena Technical Project Team meeting on April 19th. The meeting was between representatives of the Air Force, Louden Tribal Council, City of Galena, Galena City School District, and the Alaska Department of Environmental Conservation. The primary objective of this meeting was to complete comment resolution on the the Draft Final Remedial Investigation/Feasibility Study Work Plan. The team did ultimately come to resolution on the work plan and the final version is expected out by mid-May. Ann Farris

Monte Garroutte
1/5/2015 Risk Assessment Report Approved DEC approved the Human Health and Ecological Risk Assessment, Fire Protection Training Area (Site FT001). The Human Health Risk Assessment found that the cumulative carcinogenic risks and non carcinogenic hazards estimated for the receptor groups Current/future occupational worker, Near-term future resident and Long-term future resident is greater than the cumulative carcinogenic risk goal of 1 × 10-5. The report found ecologic risk with Hazard Quotients greater than 1 for terrestrial plants, terrestrial invertebrates, and vertebrates. Dennis Shepard

10/20/2016 CERCLA Proposed Plan DEC approved the Proposed Plan, Air Force Proposes Environmental Restoration Alternatives for Fire Protection Training Area (Site FT001) with Soil and Groundwater Impacts, Former Galena Forward Operating Location (FOL), Alaska. Dennis Shepard
10/26/2016 Meeting or Teleconference Held A restoration advisory board (RAB) meeting was held in Galena. Prior to the RAB meeting,Proposed plans were presented for sites Fire Protection Training Area (FT001), Waste Accumulation Area (SS018) and West Perimeter Road TCE Spill (SS025). Dennis Shepard

5/24/2017 Meeting or Teleconference Held A restoration Advisory Board meeting was held in Galena, Alaska. Preliminary site investigation results were presented from the 2016 Site Investigation for Per-Florinated Compounds (PFCs).

Dennis Shepard
11/27/2017 CERCLA ROD Approved DEC approved the Interim Record of Decision for Fire Protection Training Area (Site FT001), Former Galena Forward Operation Location, Alaska. Signature pages pending. Dennis Shepard
2/5/2018 Report or Workplan Review - Other WORK PLAN APPROVAL: Remedial Design and Remedial Action (RD/RA) Work Plan for Fire Protection Training Area, (February 2018). The RD/RA describes the activities associated with implementation of the selected interim remedy for Site FT001, Fire Protection Training Area. Jamie McKellar
7/25/2018 Update or Other Action DEC approved a request for a deviation from the approved remedial design – remedial action work plan (RD RAWP) for Fire Protection Training Area (Site FT001). The request proposed a change to the soil cover design which is being installed as part of the FT001 remedial action. The cover design changes consist of eliminating an upper membrane from the cover design and installing a 30-mil rather than 20-mil bottom liner placed directly on the ground surface as specified in the RA RDWP. The deviation from the RD RAWP does not conflict with or contradict the interim ROD for Site FT001 and will not affect the performance of the cover as intended. Dennis Shepard
8/8/2018 Site Visit DEC conducted a site visit at the Former Forward Operating Location in Galena, AK on August 8-9, 2018. A photo log is available in DEC's electronic file. Jamie McKellar
