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. |

Update or Other Action |
Staff attended the quarterly Federal Facilities Agreement (FFA) meeting for Fort Wainwright in Anchorage this week. Some of the major issues discussed included the new housing project that is proposed to be located on a contaminated site (Building 1168). The area may not be suitable for building because of permafrost; however we cautioned the housing project representative that quite a bit of additional excavation may be necessary to remove contaminated soil at the site. |

Meeting or Teleconference Held |
A two day Federal Facilities Agreement (FFA) and Stakeholders meeting was held on December 13 & 14, 2016. The main focus of the meeting was to develop a site discovery and site intake process that would satisfy requirements of the Fort Wainwright FFA, RCRA Permit, and two party agreements. The Army, EPA and DEC committed to a flowchart of the preliminary source evaluation process. Timelines were established for scoping a land use control implementation plan (LUCIP) and developing a contracting schedule for Fort Wainwright contaminated site investigations and remedial actions. Seven sites were proposed for inclusion into the FFA (three party agreement) by the Army and the RPMs documented the assignment of the regulatory path for these sites using a newly developed and agreed to signature form. |

Groundwater sample results show that PCE remains above the Record of Decision (ROD) Remedial Action Goals (RAG) at the Defense Reutilization Marketing Office (DRMO) 3-party sites, and DEC concurs with continuation of annual sampling at these locations. Groundwater samples showed continuing exceedances of diesel range organics (DRO) and volatile organic compounds (VOC) at the Building 5010 Subarea for DRMO 2-party sites, and DEC concurs with continued annual sampling of the Building 5010 Subarea and Water Supply Well. DEC concurs with continued annual sampling for DRO and VOC analysis at Former Building 1168. The institutional control (IC) inspection found that most IC’s were properly in place.No monitoring wells are recommended for installation or removal based on the monitoring results, although six non-functional wells were replaced. |
