Action Information

Action Date Action Description DEC Staff
9/19/2003 Meeting or Teleconference Held Staff attended a meeting with Air Force and EPA personnel to resolve comments on the draft Eielson Five-Year Review. Issues with the document included event-driven groundwater sampling at several contaminated sites, which we denied pending further clarification of the process, and closing numerous sites under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), but keeping them open under the State until 18 AAC 75 diesel range organic cleanup levels are met. Ann Farris
3/1/2006 Update or Other Action Staff had a telephone call with Eielson AFB to discuss their long-term monitoring program optimization. Eielson would like to apply "event-driven monitoring" to many benzene-contaminated sites, where monitoring would occur when the concentration reached the MCL at a predicted time. They are using MAKSENS to do the statistical regressions and come up with a slope indicating benzene degradation rates. This slope would predict when the concentrations would reach the MCL and monitoring would occur at that time only. They would like to apply this slope to other "similar sites" to predict when the concentrations would reach the MCL. Eielson submitted the concept to AFCEE for review, but apparently AFCEE requested more data, which Eielson did not have. At this point, DEC has not reviewed any data on this concept and requested Eielson submit a report showing the data and justification of their assumptions. Emily Youcha
7/6/2006 Update or Other Action ADEC agreed to decrease sampling of the North Boundary Wells from annual sampling to biennial. Upcoming measurements will be summer 2007, 2009, 2011, etc. Concentrations of VOCs, SVOCs, and metals in the sentinel wells have been monitored annually since 1992 and there has been no detection of contamination. Emily Youcha
9/25/2007 Meeting or Teleconference Held Contaminated Sites staff participated in a facilitated three-party meeting with the Air Force and Environmental Protection Agency (EPA) covering the environmental restoration at Eielson Air Force Base. The meeting was held in Seattle at the EPA Region 10 office. CS and the facilitator called for the meeting due to poor communication between the three parties and growing disagreements on matters fundamental to regulatory oversight on Eielson. Initially, each of the three parties was given an opportunity to talk generally about their involvement with the work at Eielson and their concerns. This lead to discussions of the Federal Facility Agreement (FFA) between the parties for base, as it appears that each party interprets specific sections of the FFA differently. Other topics discussed included the applicability of Freedom of Information Act exclusions applied to draft documents submitted to DEC, Eielson's plans for changing the frequency of groundwater monitoring for selected contaminated sites, vapor intrusion as a pathway to reconsider in the upcoming five-year review of records of decision, challenges posed by enforcing institutional controls as part of site remedies, and spill reporting coordination with DEC. Deborah Williams
11/24/2008 CERCLA ROD Periodic Review ADEC issued a letter of concurrence on the 2008 Five-Year ROD review for Eielson AFB. In the letter ADEC concurred with the current remedies but recommends further work on the following: the vapor intrusion pathway needs to be evaluated for all potential receptors at WP45/SS57 site along with further evaluation of the selected remedy to ensure the Remedial Action Objectives are going to be met. The buried drums remaining at SS35 may still contain product that may pose a potential risk to ecological and human health risk in the future. The area of buried drums identified outside of SS37 may pose a threat of an imminent release of hazardous substances and warrants further investigation or response action. As stated in the 2008 Five-Year ROD Review, the overall long-term protectiveness determination for the Sitewide OU/Garrison Slough remedy will be further investigated. A Land Use Control Management Plan should be developed and implemented. Deborah Williams
7/20/2010 Site Visit A meeting and site visit were planned at Eielson, but the meeting was moved to the DEC office when Eielson staff refused to allow EPA and DEC attorneys access to the Air Force Base. Topics discussed during the meeting were: spill reporting, Event or DQO Driven Monitoring, decommissioning of monitoring wells, documentation of groundwater sampling and analysis plans, and PCBs in Garrison Slough. It was determined that spill reporting would be addressed through the Statement of Cooperation Working Group. The Event or DQO Driven Monitoring topic created a lot of discussion. EPA and DEC did not believe the decision to go to this type of site wide monitoring was documented in the ROD, ROD Review, or met the requirements in the FFA. The Air Force stated that the topic had been discussed in meetings and briefings, DEC countered that discussions and briefings needed to culminate in Decision Documents. The Air Force had removed a large percentage of the permanent wells as part of their decision to use DQO driven monitoring. They argued that with reduced monitoring frequency it was easier to use direct push grab samples then maintain permanent monitoring wells. EPA and DEC did not agree with this approach. EPA stated that the Air Force should be working off of approved sampling and analysis plans and requested that the SAP be updated as a follow on task to the meeting. On the topic of Garrison Slough the Air Force stated that due to decreased flow and discharge of diatomaceous earth from the Water Treatment Plant that removal of sediment was no longer practical, and suggested that since the approved cleanup level had been met in most of the slough, that further removal was not necessary. DEC suggested that the site be re-evaluated due to changing site conditions. After the meeting a site visit was conducted. The DEC attorney was not allowed on base, but the EPA attorney was allowed access after she provided her enforcement credentials. During the site visit, Eielson staff discussed their plans to conduct additional ZVI injections at the WP45/SS57 site. Neither DEC or EPA had received a workplan for this action. Kim DeRuyter
8/18/2010 Meeting or Teleconference Held The purpose of the meeting was to review pertinent sections of the Federal Facilities Agreement. EPA discussed the fact that the FFA was a framework for moving toward delisting from the National Priorities List. DEC discussed the fact that it had never been clear which sites were covered under the FFA and which sites would be cleaned up under State regulations. It was agreed that DEC and the Air Force would each compile a list of sites for comparison. Deadlines for SER sites were discussed, and EPA asked that the Air Force provide deadlines for the two SER sites at Eielson. EPA reviewed the section of the FFA on quarterly and annual written progress reports, and asked that the Air Force set a date for the next report. Air Force stated that since the program had matured they no longer felt that reports were necessary, but they did agree to re-establish quarterly reporting. Annual reporting on institutional controls and land use controls had also been discontinued; the Air Force attorney discussed the fact that the Air Force had policy and guidance on this that needed to be followed. The attorneys requested this information so they could review and discuss it during their next meeting. Areas with buried drums were discussed briefly, DEC and EPA wanted further characterization and/or monitoring downgradient of known drum caches. The issue was not resolved. Kim DeRuyter
9/23/2010 Update or Other Action Contaminated Sites staff, in collaboration with EPA staff, sent a letter Eielson Air Force Base regarding concerns about the pilot study at WP45/SS57 (see 107.38.019/107.38.022). ADEC and EPA expressed concern about the inadequate horizontal and vertical delineation of the TCE plume, the lack of sampling wells more than 200 feet below ground surface, deficiencies in the July 2010 Draft Work Plan (as outlined in 20.5 of the Federal Facility Agreement), the application of Zero Valent Iron (ZVI) as an appropriate remediation technology for this site, the potential for ZVI to mobilize TCE contamination in the groundwater and CERCLA/RCRA compliance. Fred Vreeman
10/19/2010 Meeting or Teleconference Held Project manager meeting with EPA, ADEC, Eielson AFB, AFCEE R-PMO, EA. Purpose of meeting to reach an agreement on work and schedules to be established and conducted at Eielson AFB during FY11, FY12, FY13. Action items: base will provide Region 10 and ADEC with PCEADs; Eielson AFB will provide schedule for creating work plans to address monitoring requirements; Eielson AFB will evaluate current draft SER report and provide schedule for amending to fulfill FFA requirements; Eielson will provide ADEC and EPA with estimate schedule for draft base wide monitoring program work plan; Eielson agrees to communicate whether ROD amendment or ESD would be acceptable to EPA and whether an FS is required. Hannah Harrison
10/27/2010 Update or Other Action Contaminated Sites staff received a response to the joint ADEC-EPA letter sent on 23 October 2010 regarding WP45/SS57. Eielson representatives disagreed with many of the statements in the first letter and stated that they feel a "robust and comprehensive approach" to site characterization was conducted. Fred Vreeman
11/5/2010 Meeting or Teleconference Held Contaminated Sites staff participated in a teleconference with representatives from Eielson Air Force Base and EPA to discuss the response letter that ADEC and EPA received on 27 October 2010. Eielson personnel stated that it feels the actions at WP45/SS57 still constitute a pilot study because the effects are not yet clear and that the intent was not to complete a removal action. Eielson personnel agreed that additional site characterization is needed and that they will seek ADEC/EPA input throughout the process. Kathleen Beutel
11/9/2010 Site Added to Database A new site has been added to the database this site will track general information such as meetings and site visits which pertain to the base as a whole. Site specific information will continue to be added to the individual sites. Mitzi Read
11/22/2010 Meeting or Teleconference Held Contaminated Sites staff participated in a meeting with representatives from Eielson Air Force Base and EPA to discuss WP45/SS57 (see 107.38.019/107.38.022 for more information). All parties agreed to hold a comprehensive meeting next month regarding this site, including a discussion of the site history and an examination of all data available, before making any decisions on future actions at this site. Kathleen Beutel
12/2/2010 Meeting or Teleconference Held Contaminated Sites staff planned to participate in a teleconference with representatives from Eielson Air Force Base and EPA regarding several high-priority issues (WP45/SS57, Garrison Slough, Sitewide Monitoring Program, Quarterly/Annual Reporting, etc.) at Eielson AFB, but the meeting was canceled at the last minute by Eielson personnel, saying they needed to speak with their lawyer. Kathleen Beutel
1/6/2011 Meeting or Teleconference Held Contaminated Sites staff participated in a teleconference with representatives from Eielson Air Force Base, their contractor and EPA to discuss WP45/SS57 (see 107.38.019 and 107.38.022 for more information). The purpose of the meeting was to review the history of the site, identify data gaps and discuss future actions. All parties agreed to terminate all activities related to the pilot study being conducted at this site and to complete a full size characterization, starting with gathering information about groundwater flow gradients. Eielson agreed to provide EPA and ADEC with a site characterization schedule by 20 January 2011. Kathleen Beutel
1/14/2011 Update or Other Action ADEC sent a letter to Eielson AFB requesting updates on 24 active sites that have not been cleaned up adequately in compliance with state regulations. The letter requested a schedule outlining future work to bring these sites into compliance with Alaska law. Attachments to the letter included a map, a list of future requirements at each site, comprehensive site summaries and copies of previous letters from ADEC to Eielson AFB that requested further action. ADEC's previous requests largely were ignored and did not result in further site characterization or remedial action. The letter was sent to Eielson AFB with courtesy copies to the Air Force Center for Engineering and the Environment (AFCEE) and EPA. Kathleen Beutel
1/19/2011 Meeting or Teleconference Held ADEC participated in a teleconference with representatives from EPA, Eielson Air Force Base and Eielson's contractor, EA Engineering. The goal of the meeting was to identify work requirements and necessary schedules to move forward on several high-priority contaminated sites at Eielson. Although the meeting was supposed to include a review of a scope of work (SOW) for the WP45/SS57 site contaminated with trichloroethene, Eielson failed to provide a SOW as was agreed upon in an earlier meeting and the teleconference was terminated. Kathleen Beutel
2/3/2011 Meeting or Teleconference Held Eielson Air Force Base environmental personnel have struggled to plan and obtain funding for environmental cleanup activities for the upcoming field season. Contaminated Sites staff participated in two teleconferences with representatives from EPA and Eielson environmental staff the first meeting was held to give Eielson personnel a chance to explain the Air Force’s process and for ADEC and EPA to identify ways to support Eielson in this process. Subjects discussed included Project Cost Estimate Assumptions Documents (PCEADs), schedules as required by the Federal Facility Agreement and at which points in the process Eielson is required to seek input from ADEC and EPA. At the second meeting, in which Eielson personnel were not included, EPA and ADEC shared concerns over the ability of Eielson personnel to create valid schedules and obtain funding to complete environmental cleanup activities. EPA and ADEC decided to send a joint letter to Eielson and the Air Force Center for Engineering and the Environment (AFCEE) outlining their concerns. Kathleen Beutel
2/3/2011 Meeting or Teleconference Held Contaminated Sites staff met with representatives from Eielson AFB, Eielson's contractor, EPA and EPA's contractor to discuss Installation Restoration Program sites ST10/SS14 and ST13/DP26. GIS maps and site summaries were used to review historical information and identify data gaps, primarily pertaining to questions about whether soil contamination is still contributing to benzene contamination in the groundwater. Eielson personnel agreed to provide the Remedial Investigation/Feasibility Study (RI/FS) as well as any tank removal reports that can be located so that informed decisions can be made regarding future actions at these sites. A follow-up meeting was scheduled for next week. Kathleen Beutel
2/18/2011 Site Visit Staff participated in a site visit at Eielson AFB. Specific contaminated sites visited included WP45/SS57, DP44, SS67, SS37, SS41, ST13/DP26, ST10/SS14, LF03/FT09, SS61 and WP38. GIS maps were used during the site visit and several changes were noted (building demolition, monitoring wells missing, etc.). Eielson personnel stated that they had located a 1998 report on the 795 utilidor (at or near site SS37) and would provide an electronic copy to DEC/EPA staff. Eielson personnel noted that there is no money in the FY11 budget for the SER-2008 site or for the state-led compliance restoration sites. Kathleen Beutel
2/24/2011 Meeting or Teleconference Held Staff participated in the Northwest Quarterly Air Force teleconference, which included discussion of several topics related to Eielson AFB. 1) AFCEE personnel noted that they have not responded to ADEC's letter (sent January 14, 2011) regarding state-led compliance restoration sites at Eielson AFB and stated concerns that their list of compliance sites does not match the list of sites provided by the state. DEC lawyers stated that they had previously indicated a willingness to discuss discrepancies in the lists and asked Eielson's attorneys for a copy of their list, which has not yet been provided. 2) DEC attorneys said a two-party agreement is being drafted and will be provided to Eielson within approximately the next six weeks. 3) DEC staff stated the need for a comprehensive schedule. An action item (to be completed at the base level with assistance from AFCEE) agreed to in the teleconference is to develop a schedule for primary documents. 4) AFCEE will provide EPA and ADEC with a final report from its visit to Eielson after the report is finalized (currently in draft form). Kathleen Beutel
3/1/2011 Meeting or Teleconference Held Contaminated Sites staff participated in a Restoration Board Advisory (RAB) meeting at Eielson Air Force Base. This was the first RAB meeting held since 2004. In attendance were two RAB co-chairs, three military personnel, members of Eielson’s environmental restoration program and its contractor. EPA personnel were unable to attend due to federal budget restrictions but listened in via cell phone. Eielson’s restoration chief presented information about history of the environmental restoration program and briefly mentioned plans for the 2011 field season. He passed out copies of an Air Force press release dated February 25, 2011 that outlines a new policy focused on moving sites toward complete cleanup and avoiding expensive follow-up monitoring. Contaminated Sites staff identified concerns held by ADEC and EPA regarding inaction at the approximately twenty state-led compliance restoration sites, missed deadlines in the 2008 ROD Review and the need to be prepared for the 2013 ROD review. ADEC and EPA personnel reiterated the need for additional public involvement and, although ADEC and EPA personnel hoped to hold another RAB meeting three months from now, it was decided that the next meeting will be in October after one of the RAB co-chairs expressed concern about scheduling public meetings during the summer months or moose hunting season. Kathleen Beutel
3/3/2011 Meeting or Teleconference Held Contaminated Sites staff participated in a teleconference with representatives from EPA, its contractor, Eielson AFB and its contractor to discuss WP45/SS57 (TCE plume). Eielson contractors presented information regarding data gaps and proposed various techniques to collect additional data. Eielson requested permission to install transducers on existing monitoring wells to obtain hydrogeologic information. EPA and ADEC stated that a (brief) workplan must be submitted first. EPA and ADEC reiterated the need for a detailed comprehensive schedule. Eielson personnel stated that they would be prepared to discuss schedules at a meeting on March 23. Kathleen Beutel
3/18/2011 Update or Other Action Contaminated Sites staff received a response to the letter regarding compliance sites at Eielson Air Force Base (see entry from 01/14/11). Eielson personnel stated that they will fully fund all necessary cleanup activities at all of the Compliance Program sites, including those that were omitted from Eielson’s site list. Staff is working with Eielson to reconcile site lists. Kathleen Beutel
3/23/2011 Meeting or Teleconference Held Contaminated Sites staff participated in a teleconference with representatives from the Environmental Protection Agency (EPA) and Eielson Air Force Base. The goal of the meeting was to scope sites ST10/SS14 and ST13/DP26, discuss schedules for these and other sites, and agree upon a new format for and frequency of meetings. Due to time constraints and technical difficulties, the sites were not scoped. Draft schedules were discussed but uncertainty regarding the budget and contracting money remains. Bi-weekly scoping meetings (2-3 sites per meeting) will start next month and EPA personnel hope to be able to travel to Fairbanks for a week-long scoping session sometime in the future. Air Force personnel agreed to submit by March 28, 2011 a short work plan to collect hydrogeologic data at WP45/SS57. Kathleen Beutel
4/15/2011 Meeting or Teleconference Held Project manager meeting between USAF, AFCEE, EPA< EA, ADEC. The meeting discussed the review process schedules for the appropriate documents to verify work for the 2011 field season. Agencies reported on their own schedules and priority site lists, and arranged for a teleconference to discuss reviewed documents. SS37/795 utilador was discussed and a presentation was made from the 1998 795 utilidor report and RI. SS41 was presented in overview with comments from the gorup. Close proximity to another site was noted and monitoring plans suggested to expedite the monitoring of both sites. Hannah Harrison
4/25/2011 Meeting or Teleconference Held Project manager meeting between USAF, EA, EPA, TechLaw(EPA), ADEC. The purpose of this meeting was to scope site ST20 (E-7, E-8, and E-9). Agencies presented overviews of site geology, groundwater flow, and scope of current contamination. Decisions from dicussion were to include ST13/DP26 on all future maps, and to prepare coordination with airfield operations for site work on ST13. Future meetings and agendas were scheduled. Hannah Harrison
5/10/2011 Meeting or Teleconference Held Contaminated Sites staff participated in a monthly meeting/teleconference with personnel from Eielson AFB and EPA. The meeting included discussion of the Restoration Advisory Board, the final report from the Technical Assistance Visit team, budgeting, schedules and quarterly reporting. Eielson requested letters of concurrence from the regulatory agencies regarding the enforceable schedules proposed for supplemental RI/FS documents for WP45/SS57 and SS67, two Source Evaluation Reports and the Sitewide Monitoring Program. The preliminary 2012 PCEADs are now available for regulatory comment. This summer Eielson plans to complete a base-wide conceptual site model, write Phase I Source Evaluation Reports (SERs) for SER001-2008 and SER001-2010 and conduct site characterization/monitoring at WP45/SS57, SS67, ST10/SS14, ST13/DP26, SS37, ST20, ST48, LF03/FT09 and SS35. The next monthly meeting was scheduled for 16 June. Kathleen Beutel
5/13/2011 Update or Other Action Contaminated Sites staff met with Solid Waste staff and completed a file review regarding landfills (LFs) at Eielson AFB. Eielson currently has three permitted landfills: one for asbestos and coal ash (LF43), one for sludge from the electric plant and one for inert waste (Quarry Hill). Municipal waste is now hauled to the borough landfill; prior to 1987, however, LF03 was permitted for sanitary waste and received household waste, construction debris and, reportedly, waste oils, solvents and paint thinners. Between 1997 and 2007, LF03 received PCB-contaminated soil and sediment as well as fish carcasses and 8,000 pounds of metal debris from Garrison Slough. Groundwater monitoring at LF03 will occur in summer 2011. Kathleen Beutel
5/24/2011 Meeting or Teleconference Held Contaminated sites staff participated in a meeting with Eielson, ADEC, EPA, EA, Hass and Associations (EA), TechLaw (EPA). Group reviwed UFP QAPP and made comments on worksheets for future revision. Review of WP45/SS57 UFP QAPP worksheets; meeting scheduled for June for discussion of revisions. Discussion of Garrison Slough . Action item to send Yukon River and yoes Slough fish study reports; fish collection fieldwork; fish tissue analysis. Hannah Harrison
5/26/2011 Meeting or Teleconference Held Contaminated Sites staff attended a teleconference with personnel and contractors from Eielson Air Force Base (EAFB) and the Environmental Protection Agency (EPA) to discuss several issues. (1) A risk assessor contracted by Eielson presented a Risk Review and Data Gap Analysis regarding SS67 (polychlorinated biphenyls in Garrison Slough). Recommendations for 2011 include sampling fish tissue from grayling caught both on base and at several reference locations off-base. Limited sediment sampling may occur as well this year. Eielson will submit a Uniform Federal Policy – Quality Assurance Program Plan (UFP-QAPP) for this site on 08 July. (2) Eielson’s contractors presented an overview of SS35, which was a drum burial and asphalt mixing area. 2011 field work will include topographical analysis and a geophysical survey to determine the location of drums and to evaluate the possibility of re-routing Garrison Slough slightly to the west as it enters the pond. This site will be included in the UFP-QAPP submitted on 05 August. (3) Contractors from the Environmental Protection Agency (EPA) and EA Engineering (consultant for EAFB) are in general agreement regarding the overall structure and content of the upcoming UFP-QAPPs. Stand-alone UFP-QAPPs for WP45/SS57 (trichloroethylene plume) and SS67 will be produced followed by a generic (basewide) QAPP with some site-specific worksheets for several other sites. Eielson’s contractor will begin writing the UFP-QAPPs as soon as the contract money is let. Kathleen Beutel
6/14/2011 Site Visit Contaminated Sites staff participated in an all-day site visit that included WP45/SS57, SS67, LF03/FT09, ST10/SS14, DP25, ST27, SS35, SS37 and the stockpile containment area. Drums were seen in and adjacent to the pond at SS35 and both petroleum and biogenic sheens were observed on the surface of the pond. All stockpiles in the containment area were covered but two stockpiles were not labeled and from unknown locations. Kathleen Beutel

7/6/2011 Meeting or Teleconference Held Contaminated Sites staff participated in a meeting with personnel and contractors from Eielson Air Force Base and the Environmental Protection Agency to discuss proposed fish tissue and sediment sampling at SS67 (polychlorinated biphenyls in Garrison Slough). Air Force contractors have proposed collecting background data by sampling grayling and pike tissue and sediment from three reference locations (Chatanika River, Chena River and Piledriver Slough) for PCBs, pesticides and mercury. Fish tissue and sediment from Garrison Slough also will be sampled. The draft Uniform Federal Policy – Quality Assurance Program Plan (UFP-QAPP) for SS67 is due on July 08 and it is anticipated that field work will begin August 24. Due to the late start, some sampling may be postponed until 2012. A risk assessor from EPA will assist with review of the UFP-QAPP. Kathleen Beutel
7/15/2011 Meeting or Teleconference Held Contaminated sites staff participated in a meet with Eielson, EA, ADEC, EPA, TechLaw. Meeting consisted of WP45/SS57 UFP QAPP comment resolution work session. Group reviewed comments for pertinence and applicability to QAPP, and actions taken to resolve inconsistencies. Hannah Harrison
7/28/2011 Update or Other Action CS and EPA sent a joint letter regarding the next Restoration Advisory Board (RAB) meeting, which is scheduled for October 20, 2011. The March 2011 RAB meeting was poorly attended and little advance coordination with EPA and DEC occurred. The letter reminds Eielson that RAB meetings must be conducted pursuant to the Eielson Federal Facility Agreement and the federal RAB Rule and lists specific requests including advance submittal of a draft agenda, presentation materials, fact sheet and public meeting notice. The Eielson RAB currently contains only two community members and the letter reminds Eielson that they must make a serious effort to recruit additional members and solicit public participation.

8/12/2011 Meeting or Teleconference Held CS staff met with personnel from Eielson AFB and EPA to discuss several topics. (1) Field work at WP45/SS57 is scheduled to begin August 22 with arrival of the field lab on September 12. The goal for this year is to delineate the plume horizontally from 0-80 ft bgs. Field work will be guided by the passive soil gas data. Vertical plume delineation is expected to occur in 2012. (2) Work at Garrison Slough (SS67) may be deferred until 2012 to ensure that all comments are resolved. Eielson's contractors may meet with EPA's risk assessor. Eielson will adjust the schedule for SS67 documents and send to DEC and EPA for concurrence. (3) The UIC program is working to close several drywells. DEC/EPA will send approval to close the drywell at Bldg 5271 (Eielson High School). The drywell at Bldg 3386 will be entered into the database as a new contaminated site. (4) Staff discussed the SER process and noted that Phase I SERs can be quite brief and need contains only a good site map, all available data and a brief recommendation. (5) DEC reminded Eielson staff of upcoming deadlines in preparation for the October 20 RAB meeting. Kathleen Beutel

8/18/2011 Update or Other Action Contaminated Sites staff sent a letter regarding the portion of the final work plan for the Military Munitions Response Program (MMRP) Comprehensive Site Evaluation – Phase I/II that pertains to Eielson Air Force Base. The work plan states that there is only one munitions response area (MRA) at Eielson. A contractor hired by DEC noted that at least three additional MRAs should be added to the investigation. Both the response to comments on the draft final work plan and statements made during an Air Force MMRP meeting indicated that the CSE would be a fence-to-fence effort that would identify any additional MRAs.

12/29/2011 Update or Other Action Contaminated Sites staff, in conjunction with the United States Environmental Protection Agency (EPA), sent a letter to Eielson Air Force Base regarding the anti-aircraft artillery (AAA) site known as Area of Concern (AOC) 16. The letter disagrees with the Air Force’s conclusion that the limited site inspection and drum removal in 1997 were sufficient to justify a no further action (NFA) determination and reiterates the need for a source evaluation that includes analytical sampling. Similar Eielson AAA sites have significant contamination from fuels and polychlorinated biphenyls. During file review, DEC staff identified a list of 48 AOCs that received limited site inspection and corrective action from 1997-2001 and were determined by Eielson to require NFA. There are no records to indicate DEC/EPA concurrence with the work that was completed or with the NFA determinations. AOC16 appears to have the highest potential for contamination, but other AOCs also need to be re-examined. Kathleen Beutel
