Problems/Comments
The Flight Service Station (FSS) facility formerly utilized a 1,000-gallon diesel UST (28-A-1) to supply the furnace. It was located approximately four feet southeast of the FSS southeast wall. The UST was excavated on 10/10/95, drained, cleaned, cut up, and sent for recycling. Approximately 2.5 gallons of sludge were removed and disposed of off site at Alaska Pollution Controls in Palmer, Alaska. During tank removal, it was observed that soil beneath the fuel piping and the fill and vent pipes was stained and had a heavy petroleum odor. Approximately 30 cubic yards of petroleum-contaminated soil were excavated and stockpiled at the RTR/DF Building. The probable sources of release are historic leaks at fuel line fittings and overfills. In FY95, an RI was conducted and observed no groundwater contamination. Due to technical infeasibility (i.e., close proximity to the building's foundation) and relatively low risk to human health, it was recommended that the contamination be allowed to naturally attenuate. In FY99, an RI was conducted and determined that the FSS site is free of PHC contamination in soil and groundwater.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 4/12/2013 | Site Added to Database | A new site has been added to the database | Mitzi Read |
| 4/15/2013 | Cleanup Plan Approved | Revised Draft Work Plan, Decommissioning of the Cold Bay FSS, April 2013 The work plan incorporates acceptable responses to the previously supplied comments, except Comment 6. The response is fine but the concentration of pyrene for direct contact is compared to the migration to groundwater cleanup level in the second paragraph of 1.3.3.1. The document can go to a final and replacement pages would be all ADEC needs. | Debra Caillouet |

| 4/29/2013 | Cleanup Plan Approved | Final Work Plan, Decommissioning of the Cold Bay FSS, April 2013 | Debra Caillouet |
| 11/12/2013 | Document, Report, or Work plan Review - other | Draft Environmental Remediation Report, Decommissioning of the Cold Bay FSS, August 2013 | Debra Caillouet |
| 12/30/2013 | Site Characterization Report Approved | Final Environmental Remediation Report, Decommissioning of the Cold Bay FSS, November 2013 This report documents the removal of 45 cubic yards of petroleum impacted soil and the decommissioning of monitoring well MW-D. Sampling at the bottom of the excavation at 16 feet below ground surface showed diesel range organics remaining up to 4520 mg/kg. The lateral extent was not determined. Previous groundwater sampling has not detected contaminants above the groundwater cleanup levels. | Debra Caillouet |
| 7/7/2015 | Document, Report, or Work plan Review - other | DEC approved the 2015 Groundwater and VI Sampling Workplan. | Debra Caillouet |
| 12/10/2015 | Update or Other Action | DEC met with FAA PM Lance Raymore to discuss the path forward at this site. The Groundwater Monitoring and VI Sampling results from 2015 will be used to develop a remediation workplan. | Monte Garroutte |
| 7/26/2016 | Site Characterization Report Approved | DEC approved the Vapor Intrusion Investigation Report, Cold Bay Groundwater Sampling and Feasibility Study, Cold Bay, Alaska. | Monte Garroutte |
| 9/7/2018 | Document, Report, or Work plan Review - other | DEC approved the Former Flight Service Station Building 400 Site Investigation Work Plan, Cold Bay, Alaska (September 2018). The document describes site investigation activities to delineate the horizontal and vertical extent of petroleum contamination at the former Flight Service Station Building 400 at the Cold Bay Federal Aviation Administration (FAA) Station in Cold Bay, Alaska. In order to delineate the site, soil borings and groundwater monitoring wells will be installed. Analytical soil and groundwater samples will be collected for diesel range organics (DRO), residual range organics (RRO), gasoline range organics (GRO), volatile organic compounds (VOCs) and polynuclear aromatic hydrocarbons (PAHs). This work is planned to be conducted September 7-12, 2018. | Erica Blake |
| 4/1/2019 | Document, Report, or Work plan Review - other | ADEC provides comments on the "Draft Report, Site Investigation, Former Flight Service Station Building 400" dated March 2019. The draft report documents DRO soil contamination above migration to groundwater but below human health cleanup levels, and groundwater meeting the cleanup level. | Kara Kusche |
| 9/20/2019 | Update or Other Action | ADEC reviews the report responses to comment (all responses accepted by ADEC) and awaits the final draft of the March 2019 report. | Kara Kusche |
| 5/12/2020 | Site Characterization Report Approved | ADEC approves the document titled "Final Site Investigation, Former Flight Service Station Building 400 Report" dated November 2019. | Kara Kusche |
