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 |
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. |

Document, Report, or Work plan Review - other |
ADEC submitted comments after a review of the Building 1599 Remedial Investigation (RI) Work Plan. The RI aims to characterize the nature and extent of pesticide and dioxin contamination present in soil and groundwater and evaluate the human health and ecological risk. These results will be documented in an RI Report and used to develop preliminary remediation goals and considered alternatives to be evaluated in a Feasibility Study (FS).
The work plan identifies two main Data Quality Objectives (DQOs) to accomplish during this RI effort:
• Delineate the extent of pesticide and dioxin contamination in subsurface soil in the vicinity of former Building 1599, and
• Delineate the extent of pesticide and dioxin contamination in groundwater in the vicinity of former Building 1599.
Investigation Derived Waste (IDW) will also be sampled and analyzed for per- and polyfluoroalkyl substances (PFAS) as a preliminary course of action. Results will not be used in the decision making process, but could focus further sampling efforts in the future.

Document, Report, or Work plan Review - other |
Bulk action entry for B1599 and Sitewide - DEC reviewed and submitted acknowledgement of receipt for the P2179 DU Utility Intertie Project Memo - Dewatering System Overflow Events, and the Railroad North South Utility Intertie (West) CIPP Water Main construction project. Vaults within 1599 were sampled for PFAS and no detections above DEC CULs. Two dewatering overflow events occurred within a PFAS AOPI (Taxiway F). The dewatering tank was sampled for PFAS, and PFOS exceeded DEC Table C CULs. This area will be included in the PFAS RI as an AOC.

CERCLA RI Plan Approved |
DEC completed a review and backcheck of the Final Pesticide Building 1599 Remedial Investigation (RI) Work Plan. The RI aims to characterize the nature and extent of pesticide and dioxin contamination present in surface soil, subsurface soil, and groundwater in the vicinity of former Building 1599. These results will be documented in an RI Report and used to develop preliminary remediation goals and considered alternatives to be evaluated in a Feasibility Study (FS). Several comments on the draft work plan requested contamination in soil to be delineated to at least the most stringent of DEC’s promulgated cleanup levels, typically the migration to groundwater cleanup levels. DEC recognizes the importance of the intended field sampling, and the Army’s commitment to ensure analytical methods have limits of detection that are able to achieve the DEC migration to groundwater cleanup levels. As the Army did not identify the fate and transport model that will be used to evaluate the migration to groundwater pathway, DEC will evaluate the results of this field effort as presented in the draft report to evaluate whether the nature and extent of the contamination has been delineated. DEC will identify at that point if sufficient information has been gathered to determine the fate and transport of contamination over time. Data gaps may persist after the RI effort due to this oversight. DEC approved the RI Work Plan with the exception of Quality Assurance Project Plan (QAPP) Worksheets 11 and 15. |

Document, Report, or Work plan Review - other |
DEC reviewed and approved the Building 1599 Remedial Investigation (RI) Work Plan Quality Assurance Project Plan (QAPP) Addendum. The QAPP Addendum was prepared due to the addition of Analytical Resources, LLC (ARI) as a backup laboratory for pesticide analysis in groundwater. This was necessary due to the ALS Environmental – Kelso lab losing certification temporarily for Method 8081B pesticides analysis in groundwater.
ARI is a DEC approved lab that is accredited for the necessary pesticide analysis with method 8081B in groundwater. The detection limits for each of the analytes are sufficient to capture detections below state groundwater cleanup levels found in 18 AAC 75.345 (b) Table C. |
