12/12/2001	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.	Sharon Richmond
12/23/2001	Update or Other Action	Staff reviewed the final report on the soil heating feasiblity studies. Army tried 6-phase heating and radio-frequency heating and both were successful at heating the soil to about 20-25 C, which increased the remediation rates by three-fold for GRO, benzene, and toluene. The DRO sample results were inconclusive. Cost effectiveness analysis indicated the 6-phase was cost-effective, but radio-frequency was probably not. 6-phase has some health and safety issues, though, so neither were selected for implementation.	Ann Farris
12/27/2001	Update or Other Action	Staff received final report on well decommissioning at OU5 - Wells that were decommissioned were : Radio-frequency heating, unheated control site, 6-phase heating, DO15 Tracer Study Site;DO 16 Tracer Study Site;ORC well array;CRREL site; AI/E site.	Ann Farris
7/16/2003	Meeting or Teleconference Held	Fort Wainwright Restoration Advisory Board held it's last meeting on July16, 2003.	Patrice Buck
4/14/2005	Site Characterization Report Approved	Staff reviewed and provided comments to the Draft Annual Report, OU5 March 2003 to June 2004. This report summarizes operation and maintenance of the AS/SVE systems at the WQFS and Building 1060 West and groundwater monitoring. Recommendations are also included. AS probe and well redevelopment was successful and increased removal of petroleum was documented. All treatment systems will continue to operate as currently configured, the sorbent boom will be redeployed after breakup and groundwater monitoring will continue on the current schedule.	Sharon Richmond
5/17/2005	Update or Other Action	Contaminated Sites staff reviewed and approved the Operation, Maintenance & Monitoring Manual for the Operable Unit 5 Horizontal Well Remediation System on Fort Wainwright. Sampling and analysis of fuel-contaminated groundwater will continue on a semi-annual basis and the air sparge/soil vapor extraction system will remain operational.	Sharon Richmond
8/2/2005	Meeting or Teleconference Held	Site visit. EPA and DEC Water Program are determining whether to remove the Chena River from the federal list of impaired water bodies. They collected samples at this location to help with that determination. Slight sheen was observed in a small area within the boom containment in response to disturbance of riverbank sediments but quickly dissipated. EPA and DEC Water agree the current remedial approach Army is effectively controlling potential migration of contamination to the river.	Sharon Richmond
11/15/2005	Meeting or Teleconference Held	ADEC attended regularly scheduled FFA meeting with Army, EPA, the Corps and consultants. In the WQFS, benzene concentrations were below RAGs in 2005 although one well in the sparge curtain along the Chena River had benzene at 4.95 ug/L; GRO concentrations are below the cleanup level. DRO concentrations exceed cleanup levels. The treatment systems are operating in AS/SVE mode at the source area and Horizontal Well. The SVE system was shut off at the Sparge Curtain. No systems that will be shut down show evidence of contaminant rebound. Groundwater montioring will continue annually. All wells in the Bldg 1060 West area have benzene below cleanup levels One well exceeded DRO and one exceeded GRO cleanup levels. AS/SVE systems operational but hydrocarbon recovery rates are declining. A rebound study for all treatment systems except the sparge curtain will be conducted.	Sharon Richmond
2/16/2006	Meeting or Teleconference Held	Staff attended the regularly scheduled Federal Facilities Agreement meeting February 15-16, 2006.	Sharon Richmond
3/3/2006	Site Characterization Report Approved	Contaminated Sites staff reviewed and provided comments to the Draft Operable Unit 5, 2005 Annual Report for Fort Wainwright. The report describes operation and maintenance of extensive air sparge/soil vapor extraction systems and results of groundwater monitoring. In general, these four treatment systems have been highly effective, collectively removing over 80 tons of petroleum. Concentrations of benzene, toluene, ethylbenzene, and xylenes meet remedial goals at most locations. Concentrations of total aromatic hydrocarbons (TAH) and total aqueous hydrocarbons (TAqH) do not exceed state standards in monitoring wells along the bank of the Chena River. Staff agreed with the recommendation to shut down all systems except the sparge curtain which was designed to treat groundwater before it enters the Chena River. Rebound studies will continue for one year after which time changes in sampling frequency and system operational status will be evaluated. Sorbent booms will be re-installed in the river after breakup.	Sharon Richmond
9/29/2006	Long Term Monitoring Established	Groundwater will be sampled annual biannually for petroleum and natural attenuation parameters.	Sharon Richmond
9/29/2006	Update or Other Action	Second 5 year review signed by all parties.	Sharon Richmond
3/14/2008	Site Characterization Report Approved	Reviewed 2006 Annual Monitoring Report. Concentrations of groudnwater contaminants have not significantly increased since AS/SVE system were shutdown for a rebound study. TAH/TAqH concentrations not exceed in monitoring wells along the Chena River. Natural attenuation monitoring data indicate that contaminants are being degraded by native microbes. The spage curtain that runs parallel to the Chena River has effectively reduced groundwater contaminants to levels well below AWQS; it will remain operational to continue protecting the Chena River. The sorbent boom is also scheduled for deployment once breakup occurs. Groundwater will continue biannual monitoring.	Sharon Richmond

Erica Blake
3/28/2018	Document, Report, or Work plan Review - other	DEC approved the 2017 Monitoring Report, Operable Unit 5 for Fort Wainwright, Alaska. Groundwater samples were collected from the West Quartermaster’s Fueling System (WQFS) Sparge Curtain treatment system area, WQFS benzene plume area, WQFS diesel range organics (DRO) plume area, WQFS Chena River wells, and the East Quartermaster’s Fueling System (EQFS) Building 1060 wells (Flowpath D wells). The WQFS results also include observations and results from the Chena River boom deployment and monitoring. The next groundwater monitoring event is in 2018.	Erica Blake
3/26/2019	Document, Report, or Work plan Review - other	DEC approved the 2018 Monitoring Report, Operable Unit 5 (dated March 2019). The document describes groundwater sample results, showing that no significant contamination migration was occurring at the Sparge Curtain treatment system and Chena River boom area. The oleophilic biobarrier along the Chena River remains in place, although planned expansion was delayed due to high water in 2018. The benzene and diesel range organics (DRO) plumes at the West Quartermaster’s Fueling System (WQFS) were mostly found to be stable, and groundwater monitoring showed no migration of contaminants from the WQFS into the Chena River. Residual range organics were found to be exceeding remedial goals (RG) in six wells, and an exceedance of the RG was identified for trichloroethylene (TCE) in a well at the EQFS site, but evidence of biodegradation was present.The institutional control (IC) inspection found that IC’s were properly in place. Twenty wells were decommissioned, and three wells were replaced.	Kevin Fraley
6/21/2019	Site Visit	DEC staff conducted a site visit to the Chena River Boom and the Oleophilic Biobarrier test study site along the Chena River in the West Quartermaster's Fueling System area. The oleophilic biobarrier pads are a combination of sand, geotextile fabric, and a structural geocomposite that gets placed on the top of the shoreline. These pads are intended to provide a medium that biodegrades hydrocarbons before they are released to the surface water as a sheen. DEC staff observed a likely iron sheen leaching from the pads. DEC staff also inspected the Former North Airfield Hot Point Refueling site (BLM Alaska Fire Service Fuel Facility), and inspected the contaminated soil stockpile area, and the areas of the construction site where contaminated material has been encountered.

8/11/2022	Institutional Control Periodic Reporting	ADEC submitted comments for the Draft 2021 Institutional Controls (IC) report on this date. The Report details the 2021 IC inspections conducted at Fort Wainwright, Alaska (FWA). The purpose of the annual IC inspection is to evaluate the implementation and effectiveness of ICs associated with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Record of Decision (ROD) source areas and Two-Party source areas on FWA. ADEC understands best management practices (BMPs) are internal Army processes, however transparency with regulatory agencies is necessary for active sites and sites with potential or known contamination. ADEC requests information on how the BMP sites are managed and tracked. There are several source areas that have not been addressed in this report such as the Military Munitions Response Program (MMRP) sites and Chemical Warfare Material (CWM) sites. ADEC is anticipating the Army will provide new Geographic Information System mapping (GIS) to regulators when completed. This may be adequate until the Remedial Design/Remedial Action Work Plan (RD/RA WP) is developed and agreed to by the RPMs. The RD/RA WP would provide a site list, identify both the land use controls (LUCs) and the internal procedures for implementing these LUCs as required by the Operable Unit 5 (OU5) ROD. This includes periodic monitoring and reporting of the LUCs effectiveness. It also includes all areas with remaining contamination, including CERCLA sites, Two-Party source areas, MMRP sites, CWM sites, and BMP sites.	Tim Sharp

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 reviewed the final report on the soil heating feasiblity studies. Army tried 6-phase heating and radio-frequency heating and both were successful at heating the soil to about 20-25 C, which increased the remediation rates by three-fold for GRO, benzene, and toluene. The DRO sample results were inconclusive. Cost effectiveness analysis indicated the 6-phase was cost-effective, but radio-frequency was probably not. 6-phase has some health and safety issues, though, so neither were selected for implementation.

Site visit. EPA and DEC Water Program are determining whether to remove the Chena River from the federal list of impaired water bodies. They collected samples at this location to help with that determination. Slight sheen was observed in a small area within the boom containment in response to disturbance of riverbank sediments but quickly dissipated. EPA and DEC Water agree the current remedial approach Army is effectively controlling potential migration of contamination to the river.

Meeting or Teleconference Held

ADEC attended regularly scheduled FFA meeting with Army, EPA, the Corps and consultants. In the WQFS, benzene concentrations were below RAGs in 2005 although one well in the sparge curtain along the Chena River had benzene at 4.95 ug/L; GRO concentrations are below the cleanup level. DRO concentrations exceed cleanup levels. The treatment systems are operating in AS/SVE mode at the source area and Horizontal Well. The SVE system was shut off at the Sparge Curtain. No systems that will be shut down show evidence of contaminant rebound. Groundwater montioring will continue annually. All wells in the Bldg 1060 West area have benzene below cleanup levels One well exceeded DRO and one exceeded GRO cleanup levels. AS/SVE systems operational but hydrocarbon recovery rates are declining. A rebound study for all treatment systems except the sparge curtain will be conducted.

Site Characterization Report Approved

Contaminated Sites staff reviewed and provided comments to the Draft Operable Unit 5, 2005 Annual Report for Fort Wainwright. The report describes operation and maintenance of extensive air sparge/soil vapor extraction systems and results of groundwater monitoring. In general, these four treatment systems have been highly effective, collectively removing over 80 tons of petroleum. Concentrations of benzene, toluene, ethylbenzene, and xylenes meet remedial goals at most locations. Concentrations of total aromatic hydrocarbons (TAH) and total aqueous hydrocarbons (TAqH) do not exceed state standards in monitoring wells along the bank of the Chena River. Staff agreed with the recommendation to shut down all systems except the sparge curtain which was designed to treat groundwater before it enters the Chena River. Rebound studies will continue for one year after which time changes in sampling frequency and system operational status will be evaluated. Sorbent booms will be re-installed in the river after breakup.

Reviewed 2006 Annual Monitoring Report. Concentrations of groudnwater contaminants have not significantly increased since AS/SVE system were shutdown for a rebound study. TAH/TAqH concentrations not exceed in monitoring wells along the Chena River. Natural attenuation monitoring data indicate that contaminants are being degraded by native microbes. The spage curtain that runs parallel to the Chena River has effectively reduced groundwater contaminants to levels well below AWQS; it will remain operational to continue protecting the Chena River. The sorbent boom is also scheduled for deployment once breakup occurs. Groundwater will continue biannual monitoring.

The activities conducted at the WQFS sites during 2014 included groundwater monitoring, deploying and monitoring the Chena River boom system, evaluating natural attenuation, continuing Long Term Monitoring Optimization (LTMO), and conducting an IC inspection. In the approval letter it was recommended that sediment and collocated porewater sampling be conducted along the Boom area and up- and downgradient of the boom to characterize the area where the sediment and surface water Remedial Action Goals are not being met, and that in future monitoring events the recommendations sections appropriately address the remaining issues at the site. It was also recommended that the indicated area of high soil concentrations be delineated in the next monitoring event as a candidate for soil removal or targeted remediation.

Update or Other Action

2011 SVE/AS System Decommissioning After Action Report was reviewed. Contamination of soil surrounding pipelines was encountered at the Operable Unit 5 (OU5) West Quartermaster Fueling System (WQFS) soil vapor extraction/air sparge (SVE/AS) system decommissioning area. Four of the thirteen soil samples collected from the excavation had results exceeding ADEC cleanup criteria (250 mg/kg) for diesel range organics (DRO), ranging from 283 to 20,100 mg/kg. Additionally, one sample exceeded the ADEC cleanup criterion for pentachlorophenol (0.047 mg/kg) with a concentration of 7.62 mg/kg. DEC requests that the sparge curtain and SVE system remain in place until evaluation of contaminant migration to Chena River sediments is complete.

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 2018 Monitoring Report, Operable Unit 5 (dated March 2019). The document describes groundwater sample results, showing that no significant contamination migration was occurring at the Sparge Curtain treatment system and Chena River boom area. The oleophilic biobarrier along the Chena River remains in place, although planned expansion was delayed due to high water in 2018. The benzene and diesel range organics (DRO) plumes at the West Quartermaster’s Fueling System (WQFS) were mostly found to be stable, and groundwater monitoring showed no migration of contaminants from the WQFS into the Chena River. Residual range organics were found to be exceeding remedial goals (RG) in six wells, and an exceedance of the RG was identified for trichloroethylene (TCE) in a well at the EQFS site, but evidence of biodegradation was present.The institutional control (IC) inspection found that IC’s were properly in place. Twenty wells were decommissioned, and three wells were replaced.

Site Visit

DEC staff conducted a site visit to the Chena River Boom and the Oleophilic Biobarrier test study site along the Chena River in the West Quartermaster's Fueling System area. The oleophilic biobarrier pads are a combination of sand, geotextile fabric, and a structural geocomposite that gets placed on the top of the shoreline. These pads are intended to provide a medium that biodegrades hydrocarbons before they are released to the surface water as a sheen. DEC staff observed a likely iron sheen leaching from the pads. DEC staff also inspected the Former North Airfield Hot Point Refueling site (BLM Alaska Fire Service Fuel Facility), and inspected the contaminated soil stockpile area, and the areas of the construction site where contaminated material has been encountered.

Institutional Control Periodic Reporting

ADEC submitted comments for the Draft 2021 Institutional Controls (IC) report on this date. The Report details the 2021 IC inspections conducted at Fort Wainwright, Alaska (FWA). The purpose of the annual IC inspection is to evaluate the implementation and effectiveness of ICs associated with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Record of Decision (ROD) source areas and Two-Party source areas on FWA. ADEC understands best management practices (BMPs) are internal Army processes, however transparency with regulatory agencies is necessary for active sites and sites with potential or known contamination. ADEC requests information on how the BMP sites are managed and tracked. There are several source areas that have not been addressed in this report such as the Military Munitions Response Program (MMRP) sites and Chemical Warfare Material (CWM) sites. ADEC is anticipating the Army will provide new Geographic Information System mapping (GIS) to regulators when completed. This may be adequate until the Remedial Design/Remedial Action Work Plan (RD/RA WP) is developed and agreed to by the RPMs. The RD/RA WP would provide a site list, identify both the land use controls (LUCs) and the internal procedures for implementing these LUCs as required by the Operable Unit 5 (OU5) ROD. This includes periodic monitoring and reporting of the LUCs effectiveness. It also includes all areas with remaining contamination, including CERCLA sites, Two-Party source areas, MMRP sites, CWM sites, and BMP sites.
