Problems/Comments

The East Quartermaster Fueling System (EQFS) area covers approximately 40 acres between Taxiway 18 and the Chena River between Building 1579 to the southwest and Building 1054 to the northeast. The EQFS was used for vehicle storage and maintenance, dry cleaning, fuels testing, refueling, pesticide storage mixing, and waste storage. Suspected sources include spills and leaks from pipelines, fueling stations and undocumented spills. The EQFS area included underground storage tanks (USTs), aboveground storage tanks (ASTs), a pump house, and fueling islands which have all been removed. Contaminants of concern at the EQFS are benzene, 1,2-ethylene dibromide, 1,1,1-trichloroethane (1,1,1-TCA) and trichloroethene (TCE) in the groundwater, and petroleum products and xylenes in the soil. To address the petroleum and solvent contamination an air sparge (AS)/soil vapor extraction (SVE) system was installed on the east side of Building 1060 in 1994. The system operated from 1994 to 1999 on the east side of Building 1060 before the system was moved to the west side of Building 1060 in 2000. By 2005, the groundwater remedial action goals had been met, so the system was turned off and decommissioned in 2010. Long-term monitoring activities at the EQFS have been focused on evaluating the residual groundwater contamination in the former Building 1060 treatment area. In 2017 monitoring wells on the east side of Building 1060 were sampled and trichloroethene (TCE) was detected above the remedial action goal of 5 micrograms per liter. Monitoring wells at the Building 1060 area are sampled annually to monitor the TCE and petroleum concentrations. Other areas within EQFS, the remedy in the Record of Decision (ROD) was for natural attenuation. Institutional control inspections are conducted annually. Long-term monitoring efforts are expected to continue at this site. This site also includes spill no. 12309912901; contaminated gravel discovered on 5/8/2012 during a parking lot repaving project at Building 1060. The corresponding Army HQAES site number is: 02871.1071.

12/12/2001 Institutional Control Record Established 1. All organizations conducting activities on United States Army Alaska (USARAK) controlled land are responsible for complying with established institutional controls (ICs). ICs are administrative, procedural, and regulatory measures to control human access to and usage of property. They are applicable to all known or suspected contaminated sites where contamination has been left in place. 2. These controls have been established to implement the selected remedial actions agreed upon by the U.S. Army (Army), the U.S. Environmental Protection Agency (USEPA), and the Alaska Department of Environmental Conservation (ADEC) in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended by the Superfund Amendment Reauthorization Act (SARA). These controls also apply to remedial actions agreed upon under Two-Party Compliance Agreements. These agreements are concluded between USARAK and ADEC and apply to petroleum/oil/lubricants- (POL) contaminated sites. 3. ICs such as limitations on access, water use, excavations, and property transfers will supplement engineering controls as appropriate for short-term and long-term management to prevent or limit human and environmental exposure to hazardous substances, pollutants, or contaminants. Specific ICs include, among other things: limitations on the depth and location of excavations, prohibition of or restrictions on well drilling and use of ground water, requirements for worker use of personal protective equipment, site monitoring, and prohibition of certain land uses, types of vehicles, etc. 4. Organizational units, tenants, and support/contractor organizations must obtain an Excavation Clearance Request (ECR) for all soil disturbing activities impacting soils six inches or more below the ground surface. The review process for approval of an ECR begins with the identification of the current status (known or suspected hazardous waste site or “clean” site) of a work location. ECR’s for work in known or suspected hazardous waste sites: a. will include specific limitations and controls on such work; b. will include specific IC procedures, and notification, monitoring, reporting, and stop work requirements; c. may include procedures for management, characterization, and disposal of any soil or groundwater encountered or removed; d. will identify “project managers” for both the unit/contractor requesting the work and DPW Environment Resources. 5. The DPW project manager will conduct on-site inspections of each work site (at which ICs apply) to determine continued compliance with the terms and conditions of the approved ECR. DPW has the authority to revoke ECR approval if the specified terms and conditions are not being met. ECR forms are available at the Customer Service Desks at: a. Building 730 at Fort Richardson; b. Building 3015 at Fort Wainwright; c. Building 605 at Fort Greely. 6. USARAK has negotiated (with USEPA and/or ADEC) decision documents and/or Records of Decision (RODs) that mandate the implementation of ICs USARAK Directorate of Public Works, Environmental Resources Department (PWE), maintains copies of all decision documents and RODs requiring ICs in its real property files. PWE provides regularly updated post maps showing all areas affected by ICs. These maps can easily be accessed by using an approved intranet mapping interface application. Copies of these maps will be available to each directorate, activity, and tenant organization. To ensure the effectiveness of ICs, all organizational units and tenant activities will be informed on an annual basis of ICs on contaminated soils and groundwater in effect near their facilities. 7. ICs are enforceable by the U.S. Environmental Protection Agency (USEPA) and the Alaska Department of Environmental Conservation (ADEC). Failure to comply with an IC mandated in a decision document or ROD will violate the USARAK Federal Facility Agreement and may result in stipulated fines and penalties. This does not include the costs of corrective actions required due to violation of an established IC. Sharon Richmond

Erica Blake
3/28/2018 Document, Report, or Work plan Review - other DEC approved the 2017 Monitoring Report, Operable Unit 5 for Fort Wainwright, Alaska. Groundwater samples were collected from the West Quartermaster’s Fueling System (WQFS) Sparge Curtain treatment system area, WQFS benzene plume area, WQFS diesel range organics (DRO) plume area, WQFS Chena River wells, and the East Quartermaster’s Fueling System (EQFS) Building 1060 wells (Flowpath D wells). The WQFS results also include observations and results from the Chena River boom deployment and monitoring. The next groundwater monitoring event is in 2018. Erica Blake
3/26/2019 Document, Report, or Work plan Review - other DEC approved the 2018 Monitoring Report, Operable Unit 5 (dated March 2019). The document describes groundwater sample results, showing that no significant contamination migration was occurring at the Sparge Curtain treatment system and Chena River boom area. The oleophilic biobarrier along the Chena River remains in place, although planned expansion was delayed due to high water in 2018. The benzene and diesel range organics (DRO) plumes at the West Quartermaster’s Fueling System (WQFS) were mostly found to be stable, and groundwater monitoring showed no migration of contaminants from the WQFS into the Chena River. Residual range organics were found to be exceeding remedial goals (RG) in six wells, and an exceedance of the RG was identified for trichloroethylene (TCE) in a well at the EQFS site, but evidence of biodegradation was present.The institutional control (IC) inspection found that IC’s were properly in place. Twenty wells were decommissioned, and three wells were replaced. Kevin Fraley

8/11/2022 Institutional Control Periodic Reporting ADEC submitted comments for the Draft 2021 Institutional Controls (IC) report on this date. The Report details the 2021 IC inspections conducted at Fort Wainwright, Alaska (FWA). The purpose of the annual IC inspection is to evaluate the implementation and effectiveness of ICs associated with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Record of Decision (ROD) source areas and Two-Party source areas on FWA. ADEC understands best management practices (BMPs) are internal Army processes, however transparency with regulatory agencies is necessary for active sites and sites with potential or known contamination. ADEC requests information on how the BMP sites are managed and tracked. There are several source areas that have not been addressed in this report such as the Military Munitions Response Program (MMRP) sites and Chemical Warfare Material (CWM) sites. ADEC is anticipating the Army will provide new Geographic Information System mapping (GIS) to regulators when completed. This may be adequate until the Remedial Design/Remedial Action Work Plan (RD/RA WP) is developed and agreed to by the RPMs. The RD/RA WP would provide a site list, identify both the land use controls (LUCs) and the internal procedures for implementing these LUCs as required by the Operable Unit 5 (OU5) ROD. This includes periodic monitoring and reporting of the LUCs effectiveness. It also includes all areas with remaining contamination, including CERCLA sites, Two-Party source areas, MMRP sites, CWM sites, and BMP sites. Tim Sharp

3/7/2023 Document, Report, or Work plan Review - other DEC has completed a backcheck and approved the Final Hangar 1 Environmental Sampling Report dated April 8, 2022. The tech memo report summarizes the results of the environmental soil sampling activities conducted at Building 1557 (Hangar 1) on Fort Wainwright, Alaska. Work was conducted for the purpose of soil characterization related to future construction and soil disturbance activities. The report documents that undelineated contamination remains in situ in the near-surface soils (0 to 4 feet bgs). The extent of contamination is unknown, although the exceedances are believed to be the result of discrete fuel surface releases and not likely related to contamination as the East Quartermaster’s Fueling System (EQFS) source area. The Army must characterize and cleanup the contamination in accordance with 18 AAC 75.325. Future planned road improvement and construction activity in this area will likely disturb contaminated soil. DRO, benzene and naphthalene are present above DEC cleanup levels within 30 feet of Building 1557. Tim Sharp
5/3/2023 Document, Report, or Work plan Review - other DEC sent comments on the Draft Doyon Utilities (DU) Addendum to the Post-Wide Sampling and Analysis Plan (SAP), P2371 Steam Powered Lift Station F5-6-9. The SAP Addendum details proposed upgrades to two steam powered lift stations and trenching 30 linear feet to bury electrical conduit in the area of an active contaminated site, specifically the East Quartermaster Fueling System (EQFS). The project is also located downgradient of Hangar 1, which is a per- and polyfluoroalkyl substance (PFAS) area of potential interest (AOPI) identified in the PFAS preliminary assessment/site investigation (PA/SI), and the Bldg 1565 Parking Lot site, which has an undelineated diesel range organics (DRO) exceedance of its migration to groundwater cleanup level (CUL). Of note, DEC has been approving on a project-by-project and site-by-site basis for soil contaminated with PFAS to be placed back into the ground during construction projects without a two-foot cap as long as the known concentrations are below DEC human health CULs. As this project is taking place on the footprint of a National Priorities List (NPL) site, DEC defers to EPA approval for using PFAS contaminated soil below state promulgated human health CULs as backfill.
