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 teleconference with Army, Corps of Engineers, and their contractors to discuss the Petroleum, Oil, and Lubricants (POL) Source Removal- Work Plan, Sampling Analysis Plan, and Environmental Protection Plan. The project entailed removing an abandoned fuel pipeline which runs from the tank farm to the airfield approximately 13,000 feet. Sections of the line have been removed in the past. The plan is to remove all remaining pipe except under roads, railroad tracks, airfields, and through areas with active remedial systems. It is estimated that 250 cubic yard of contaminated soil will be removed. Contaminated soils will be segregated and taken to OIT for treatment. Staff sent a comment letter on 4/8/03. |

Document, Report, or Work plan Review - other |
Draft Work Plan Environmental Investigations various Sites, Fort Wainwright Alaska January 2015 was reviewed. This this work plan addresses 17 sites at Fort Wainwright. The plan was written in UFP-QAPP but has major deficiencies requiring a complete rewrite of the document. Detailed comment was sent to the Army. |

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. |

Update or Other Action |
DEC approved the Final Data Gap Analysis Report, Birch Hill UST Farm. The report indicates that approximately 555 cubic yards (CY) of contaminated soil remain at the former UST346 location and excavation of this residual petroleum soil contamination is recommended. The estimate may be low due to incomplete delineation.
Localized “hot spot” locations (UST-371, UST-372, and UST-381) upgradient of the former FEP
and Milepost (MP 2.7 & 3.0) sites have been delineated laterally and vertically. Contamination at these areas is localized, does not appear to be migrating, and is not an identified source of contamination for the MP sites or area along Birch Hill Loop Road. Further delineation of soil contamination, cleanup and soil removal actions are ongoing and conducted under Site: Fort Wainwright (OU-3) FE Pipeline MP2.7/3.0 FTWW-084, Hazard ID 1673, File Number 108.38.002.02. |
