These ICs include: a prohibition on the installation or use of drinking water wells, a requirement that all monitoring wells are secured with locks, any activity that may result in exposure to contaminated GW or moving contaminated GW requires approval of CES/CEV, any activity disturbing a remedial action requires approval of CES/CEV, any activity that may result in exposure to or removal of contaminated soil requires approval of CES/CEV, if contaminated soil or GW are removed from the source, they must be disposed of or treated in accordance with regulation, and a requirement to notify ADEC and EPA of any proposal to change the existing land use or land use controls at the site. Ann Farris
3/24/1997 Update or Other Action Site updated by Shannon and Wilson, based on the Air Force Relative Risk Evaluation Worksheet dated 10/23/95. S&W
12/19/2001 Long Term Monitoring Established Landfarm is closed, site is in long-term monitoring. Staff received draft 2001 Monitoring Report. 5 wells sampled for VOCs, GRO, DRO, SVOCs, and metals. 1 well sampled for just PCBs. Benzene (15ppb), PCE (13 ppb), TCE(22 ppb), and vinyl chloride (2.37 ppb) found above MCLs each in just one well, but all different wells. Ann Farris
12/26/2001 GIS Position Updated Worked with Heather Goldman obtaining GIS latitude and longitude from 1:63,300 topographic map. Heather Goldman
1/14/2002 Site Number Identifier Changed Changed Workplan from X1 to X9 to reflect presence of a hazardous substance. Ann Farris
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
1/9/2004 Update or Other Action Staff is reviewing the draft final Five-Year Review for Eielson Air Force Base. The majority of ADEC’s comments on the original draft document have been addressed. There are a few items that are still not satisfactory, but staff expects to get resolution on these items in the next week and have a document ready for signature by the end of the month. Ann Farris
4/21/2004 Meeting or Teleconference Held Staff met with personnel from Eielson Air Force Base regarding some dewatering activities planned for this summer. One project was determined to not be near any contaminated sites so is being dealt with under the normal wastewater discharge permits. The second project actually calls for installing a drinking water well for a dog kennel and the contractor is requesting to discharge the development water directly to the land. Staff is working with the Air Force personnel and the contractor to ensure the well is in a safe location. Ann Farris
8/26/2004 GIS Position Updated Position acquired using "Base MW Map 2004" CAD drawing from EIAFB georeferenced to QuickBird Satellite imagery, NAD27. Torsten Ernst
10/11/2004 GIS Position Updated Coordinates updated with values acquired by Emily Youcha during a site visit using a handheld GPS unit. Torsten Ernst
6/24/2005 Update or Other Action Staff recieved the workplan for the 2005 sitewide monitoring. Five wells will be sampled for VOCs, SVOCs, and metals. Lower detection limits are needed for VOCs and SVOCs. Sample results from previous sampling events indicate detection limits for vinyl chloride, pentachlorophenol, and bis(2-ethylhexyl)phthalate were above cleanup levels. ADEC recommended the use of EPA Method 8270 SIM to lower detection limits. This years sampling event will focus on monitoring potential contaminant migration toward Garrison Slough. Emily Youcha
6/24/2005 Update or Other Action Staff received the results of the 2004 sampling efforts. Samples were collected from 6 wells for VOC, SVOC, and metals analysis. VOCs remain in the ground water at concentrations above cleanup criteria. Sample results from 03M19 show an increase in benzene concentration since the well was installed in 2003. VOCs exceeded cleanup criteria in the LF03 source area well 03M08 in 2002 and trace amounts of cis-1,2-DCE were detected in six 2004 samples collected between the source areas and Garrison Slough. Emily Youcha
11/22/2005 Meeting or Teleconference Held EPA and ADEC would like Eielson to define the solid waste management units more clearly for LF03/FT09. Eielson indicated that burial areas exist further to the west than the existing boundaries and currently contamination occurs in that western area, approaching Garrison Slough. Emily Youcha
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
3/6/2006 Update or Other Action Staff reviewed the 2005 long-term monitoring results. Well 03M08, located within the landfill boundary on the eastern edge, shows decreasing concentrations of benzene and TCE. Well 03M13, located downgradient and outside the boundary of the landfill and the firetraining area, shows an overall decreasing benzene concentration trend since 1989, but stable since 2001. Well 03M019, also located downgraident and outside the boundary of the landfill and the firetraining area and adjacent to Garrison Slough, shows a drop in benzene concentrations from 11 ppb in 2004 to 7.0 ppb in 2005. The area of contaminated ground water to the northwest of LF03 source area (near Garrison Slough) is of some concern to DEC. This area of benzene,TCE, and PCE-contaminated ground water is outside of the defined LF03 source area boundary. Upgradient wells within the LF03 boundary (03M07, 03M06, 03M05, and 03M02) have been shown to be clean during the past 10 years of sampling. This general area is also thought to have additional buried drums and debris outside the boundary of LF03. It is unclear as to whether the contamination migrated out of the LF03 boundary or is from an additional source area; DEC requested additional clarification regarding this issue within the report text. The results of the data show the need for properly defining and characterizing burial areas or solid waste management units, and delineating and tracking contaminant plumes over time. 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
5/7/2008 Exposure Tracking Model On Hold This site is combined with LF03 and is ranked under that Database entry. Deborah Williams
7/14/2008 Meeting or Teleconference Held ADEC participated in Eielson's 5 year ROD Review with EPA and Eielson. The sites covered in the ROD Review were the following: ST20, ST48, SS50-52, ST10/SS14, ST13/DP26, DP44, WP45/SS57, ST56, SS61, DP25, ST58, LF03/FT09, WP38 and SS67. Bioventing systems for ST10/SS14 and ST13/DP26 will cease operation during the summer of 2008. ADEC is concerned about LTM issues with SS35 and SS37 because of the potential for spills to be released from buried containerized wastes which are present at both of these sites. The vapor intrusion pathway will be evaluated at many of the sites where there are volatile compounds as a COC at the site and where there are potential receptors. All of these sites will be incorporated into Eielson's Land Use Control plan for the Base and the long term monitoring will be Event Driven Monitoring Program. 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
