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. |

Meeting or Teleconference Held |
ADEC met with Army, EPA, the Corps, and consultants for regularly scheduled FFA meeting. Valve Pit A: Air flow from Zone 4 (downgradient) AS will be diverted to Zone 2 to better treat persistent benzene contamination. Nine MW will be sampled annually. Valve Pit B: AS/SVE system decommissioned in 2005. Two years of groundwater monitoring indicate that contaminant rebound is not occurring. Four wells will sampled annually. Valve Pit C: AS/SVE system decomissioned in 2005. At downgradient monitoring point, benzene, TAH and TAqH were slightly above RAG but lower than in 2004. Annual groundwater sampling will continue. Central Header: Zones 6 and 7 operated continuously in AS/SVE mode in 2005. AS probes along western edge operated continuously and Zones 1,2,3,4,5, and 8 have been shutdown. VOC removal in this system has declined dramatically and benzene was only detected in one exhaust sample. Air flow in Zone 7 will be maximized. Zone 6 will be shut down. Excess airflow from Zone 8 will be diverted to the Truck Fill Stand and AS probes along western boundary. Rebound studies in other zones and semi-annual groundwater monitoring for EDB/VOCs will continue. Annual groundwater monitoring for lead will continue. AS/SVE system at Former Bldg 1144 will operate in 4 zones and 4 other zones will be evaluated for contaminant rebound. Annual groundwater sampling will continue. The Eight-Car Header AS/SVE system was expanded. Some zones are undergoing rebound studies; annual groundwater monitoring will continue. |

Document, Report, or Work plan Review - other |
Reviewed and approved After-Action Report. In November 2011, surface soil of the gravel pad beneath former Buildings 1128, 1129, and 1130 was investigated for potential contamination at the gravel pad/native soil interface. Two soil samples, with diesel range organics (DRO) concentrations of 260 and 270 mg/kg, exceeded the DEC cleanup criterion of 250 mg/kg for DRO. However, it does not appear that storage and/or maintenance activities at former Buildings 1128, 1129, or 1130 were the source of significant environmental contamination at this site. Excavation to the gravel pad/native soil interface was not successful at all locations due to frozen soil conditions but the existing gravel pad was well-characterized. Residual subsurface fuel contamination detected during previous investigations appears to have resulted from activities associated with the former Fairbanks Fuel Terminal (OU3), not activities associated with the ROLF Buildings. |
