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 |
Contaminated Sites staff attended a meeting with the US Army, the Corps of Engineers and Tatitlek Construction, Inc. (Tatitlek) regarding operation of an air sparge/soil vapor extraction (AS/SVE) system on Fort Wainwight. The treatment system is located near Tatitlek's office trailer and workers noticed a strong odor when the system began operation in October 2005. A catalytic oxidizer was installed to reduce off-gas emissions. Results of ambient and indoor air monitoring during system operation indicated that petroleum hydrocarbons were either not detected or not present at concentrations that exceed Occupational Safety and Health Adminstration or National Institute of Occupational Safety and Health screening levels, however, concerns by site workers led the Army to shut down the system. It seems likely that the odors arise during operation of the AS system so the Army will operate the SVE system only and perform an air quality evaluation this week. The SVE system will then be shut down until lab results are received. Plans to operate the AS/SVE system during non-business hours are also being considered. |
Sharon Richmond |

Meeting or Teleconference Held |
Staff attended a meeting at Fort Wainwright with DPW staff and workers with Tatitlek Construction to discuss results of air monitoring during SVE operation. No samples exceed time-weighted recommendations for worker exposure. The SVE system and thermal oxidizer will be restarted May 5, 2008. Mactec staff will be available to address any concerns noted during this period of operation. The system will then operate continuously until PMs decide to shut it down. |

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. |

DEC approved the 2017 Monitoring Report, Neely Road Building 3570 Former PX Gas Station (dated April 2018). The document describes 2017 groundwater monitoring activities and an institutional control (IC) inspection at the Neely Road – Former Building 3570 PX Gas Station (Neely Road) site on Fort Wainwright, Alaska. The following contaminants of concern (COCs) were detected above DEC cleanup levels; diesel range organics (DRO), 1,2,4-trimethlybenzene, 1,3,5-trimethylbenzene, ethylbenzene and naphthalene. No compliance issues were noted during the IC inspection. Because benzene has shown an increased trend in monitoring well AP-9003, continued semi-annual sampling is recommended. The next round of groundwater samples is planned for Spring 2018. |

DEC approved the 2018 Monitoring Report, Neely Road Building 3570 Former PX Gas Station (dated December 2018). The document describes 2018 groundwater monitoring activities and an institutional control (IC) inspection. The following contaminants of concern (COCs) were detected above DEC cleanup levels; diesel range organics (DRO), trichloroethene (TCE), 1,2,4-trimethlybenzene, 1,3,5-trimethylbenzene, ethylbenzene, and naphthalene. Manganese is not a COC for this site, it is part of the geochemical parameter monitoring. DEC recently added a cleanup level for manganese, and all but one sample result was above the cleanup level. No compliance issues were noted during the IC inspection. Due to the increasing trends in AP-9003 and the continued evaluation of solvent detections in AP-9685, the semiannual sampling frequency is recommended for future sampling events.

DEC has completed a backcheck of the response to comments for the P2413 Neely Road Phase 2 Sampling and Analysis Plan (SAP) Addendum. The SAP Addendum is to be used in conjunction with the 2020 Doyon Utilities (DU) Fort Wainwright, Alaska (FWA) Postwide SAP. The project will excavate the depth required to access the utilidor lids and vaults for maintenance and repair (up to five feet below ground surface) and is not expected to impact groundwater. This project will complete rehabilitation to approximately 4,000 linear feet (LF) of utilidor along Neely Road, between 9th Street and Meridian Road.
According to the figures, it appears the project will impact soil at four active contaminated sites:
• Fort Wainwright Fire Station #2 (File Number 108.38.163)
• Fort Wainwright Neely Road Fire Training Area (File Number 108.38.164
• Fort Wainwright Bldg 3562 PX Gas Station USTs 177,179,180 CC-FTWW-120 (File Number 108.26.060)

Bulk action entry for Fort Wainwright Two-Party monitoring sites - on this date, DEC received and approved the final 2022 Two-Party Sites Annual Monitoring Report. Following the recommendations from the 2021 report, sampling and analysis of gasoline range organics (GRO) was discontinued at the Former Building 3564 site in 2023. However, after review of the 2022 results, GRO should continue to be analyzed further and will be included in the 2024 sampling program. Plume stability analysis for Former Building 3654 indicate increasing trends of contaminant mass. The Army will evaluate the 2023 monitoring data as well as the historical investigation and remedial activities at the site to determine if a soil removal action should be considered in the future to reduce the contaminant mass migrating to the groundwater.
A minimum of five temporary well points and two additional wells be installed at the Former Building 2250 site to further delineate the extent of the groundwater contamination. Additionally, DEC is anticipating the 2022 IDW technical memorandum with DRMO Yard Building 5010 purge water PFAS results in fall of 2023. |
