Record of Decision |
The OU5 ROD signed and distributed in May 1999. Lead-contaminated soil would no longer be managed as part of OU3; it would be managed as part of OU5. The Remedial Action Objectve (RAO) for lead-contaminated soil was to limit human and terrestrial receptor exposure to lead through land use and access restrictions. These restrictions were incorporated into the Fort Wainwright Master Plan. |

Institutional Control Record Established |
Post-wide ICs updated.
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. |

Site Characterization Workplan Approved |
The US Army has indicated that they would like to pursue site closeout with no institutional controls. Proposed remedial goals for lead-contaminated soil are ADEC cleanup levels of 400 mg/kg (residential) and 1000 mg/kg (industrial). Staff approved a work plan to sample soil around tanks on 8/11/05. The purpose of sampling is to determine the volume of soil that will require treatment/disposal. |

Site Characterization Report Approved |
Over 200 samples were collected and submitted for analysis in September 2005. Lead was detected in every sample. Concentrations ranged between 6.81 mg/kg to 14,500 mg/kg in surface samples and between 9.66 and 143 mg/kg in subsurface samples. No petroleum constituents were present at concentrations above ADEC cleanup levels. The estimated volumes of contaminated soil are approximately 2,500 and 2,800 cubic yards for the 1,000 mg/kg and 400 mg/kg cleanup levels, respectively, to a depth of 1 foot. |

Draft 2012 Monitoring Report, Operable Unit 5, Fort Wainwright, Alaska, March 2013
ADEC has no objections to the implementation of the recommendations shown below, but asks that the fence at the Birch Hill tank farm be inspected on a monthly basis during the summer months due to the historical frequency of breaches.
The sparge curtain should remain off, the Chena River Boom will be installed and visual monitoring will continue and passive sampling of the surface water utilizing the GORE Modules. The fall groundwater sampling should occur.
Groundwater sampling should continue to be conducted annually for all wells associated with the area of elevated benzene, the wells along the Chena River, and the WQFS DRO plume. Sampling should be conducted in the spring when water levels are typically lowest and petroleum hydrocarbon concentrations are typically highest.

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.

DEC approved the Lead Soil Investigation Report, Soil Investigation and Remedial Action at Birch Hill Above Ground Storage Tanks, U.S. Army Garrison Alaska (dated May 2019). The document describes results from 2018 lead soil investigation and remedial action activities at the Birch Hill Above Ground Storage Tanks, Remedial Area 1A at Fort Wainwright, Alaska (FWA). Soil investigation at former above ground storage tank (AST) locations 304-307, 311-314, and 317-318 was conducted with X-Ray Fluorescence field screening and laboratory analytics. Field screening and laboratory data were well-correlated. Former AST locations 307, 312, and 313 were found to have lead contamination exceeding the DEC cleanup level. Former Truck Fill Stand AST locations 317 and 318 were found to have exceedances of DEC cleanup levels for lead on asphalt tank pans, but not in soil samples at the tank locations. The remainder of the former AST locations exhibited no lead exceedances in soil or on tank pads. |

DEC approved the Final POL Soil Investigation Report, Birch Hill Above Ground Storage Tanks, Remedial Area 1A, Fort Wainwright, AK Dated February 2020. Screening for petroleum-contaminated soil at 18 former above ground storage tank sites was largely unsuccessful when ultraviolet optical screening tool (UVOST) and Optical Imaging Profiler technologies were employed. Thus, soil borings in combination with photoionization detector (PID) and PetroFLAG screening and soil analytical samples were used to delineate the vertical and horizontal extent of soil contamination above DEC cleanup levels at the former tank sites. The amount of contaminated soil at each tank site was estimated by volume based on the screening and soil samples, and totals approximately 65,604 cubic yards. Petroleum-contaminated soil was identified at 17 of the 18 former tank sites. Additionally, 1,1,2,2-tetrachloroethane, a chlorinated solvent, was found to exceed DEC cleanup levels in one soil boring sample. |
