Problems/Comments

Former Building 2250 was a Quonset hut located on the Fort Wainwright golf course that was used for pesticide storage and mixing. The building was removed in 1991. A remedial investigation (RI) was conducted at the site, and petroleum, oil and lubricants (POL) were identified in the soil and groundwater. An air sparge/soil-vapor extraction (AS/SVE) system was installed at the site in 1995 and operated until 2004. The AS/SVE system was decommissioned and removed from the site in 2011. Three monitoring wells are sampled on a five year frequency for diesel range organics (DRO), dissolved iron and sulfate. DRO remains in the groundwater above DEC cleanup levels in two out of the three wells sampled every five years. Groundwater monitoring at this site is expected to continue on a five year frequency, coinciding with the Five-Year Reviews. The corresponding Army HQAES site number is: 02871.1077.

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

Tim Sharp
10/30/2023 Document, Report, or Work plan Review - other Bulk action entry for Fort Wainwright Two-Party monitoring sites - on this date, DEC received and approved the final 2022 Two-Party Sites Annual Monitoring Report. Following the recommendations from the 2021 report, sampling and analysis of gasoline range organics (GRO) was discontinued at the Former Building 3564 site in 2023. However, after review of the 2022 results, GRO should continue to be analyzed further and will be included in the 2024 sampling program. Plume stability analysis for Former Building 3654 indicate increasing trends of contaminant mass. The Army will evaluate the 2023 monitoring data as well as the historical investigation and remedial activities at the site to determine if a soil removal action should be considered in the future to reduce the contaminant mass migrating to the groundwater. A minimum of five temporary well points and two additional wells be installed at the Former Building 2250 site to further delineate the extent of the groundwater contamination. Additionally, DEC is anticipating the 2022 IDW technical memorandum with DRMO Yard Building 5010 purge water PFAS results in fall of 2023. Cascade Galasso-Irish
