Problems/Comments

Building P-80 (a.k.a. Building 10333) was used as an NSGA community center and also housed automated data processing and training activities. The building was abandoned sometime after October 1991 because it contained asbestos. Former UST 10587 and AST 10333 were located west of Building P-80. Both stored JP-5 for heating and were removed in 1994. UST 10579 was used to supply JP-5 fuel to the generator building P-81. It was reported to have been removed in 1991. Free product was detected and removed from several wells. An interim remedy of free product recovery was selected under SAERA in OU A ROD. Site removed from OU A ROD by OU A ROD Amendment for regulation under 18 AAC 75. Decision Document for Petroleum Sites with No Unacceptable Risks signed on May 20, 2005. A final remedy of limited monitoring was selected in the decision document for the site. The 2005 groundwater monitoring report shows that groundwater contamination is at or below groundwater clean-up levels. One more sampling round below at or below current levels will make the site eligible for closure.

4/5/2007 Update or Other Action Received the Final Remedial Action Closure At Four Petroleum Sites that details remedial actions at Tango Pad, SA-77, SA-82, adn ASR-8. The Department's comments have been addressed in the final report. Guy Warren
4/25/2007 Update or Other Action Submitted comments on the Draft Annual Ground Water Monitoring Report. Primary areas of concern include: increasing trends in contaminant levels at several sites, Increased free product, and adherence to field sampling procedures. In general it appears that declining ground water levels are responsible for the increase in free product and dissolved contaminant concentrations. The Navy and DEC have agreed to reinstate free product recovery at those sites showing increases in free product. Guy Warren
7/26/2007 Update or Other Action Received Final Annual Ground Water Monitoring Report, September 2006. The Department's comments have been addressed in the Final Report. The Navy has agreed to conduct additional free product recovery at those sites with increassed free rpoduct. The Navy has agreed to evaluate conditions at several sites with increasing contaminant trends to determine if additional investigation or remediaiton is required. Guy Warren
7/31/2007 Update or Other Action This week CS staff submitted a letter to the Navy acknowledging that the limited soil removal specified for this site in the Decision Document for Petroleum Sites with No Unacceptable Risk has been completed to the Department’s satisfaction. The decision document specified removing surface soil contamination in a 10ft x 10ft area to a depth of six feet below ground surface. The site is not eligible for site closure as ground water monitoring is on-going and contaminant concentrations in ground water do not meet the monitoring end point requirements. Guy Warren
2/13/2008 Update or Other Action Draft 2007 Annual Groundwater Monitoring Report received. Meghan Dooley
3/28/2008 Update or Other Action Submitted comments on the Draft Annual Ground Water Monitoring Report. Primary areas of concern include: consistency in recommendations for depth to water measurements in determining groundwater elevation, consistency throughout sampling and reporting of FPR, optimization of monitoring regimes at specific sites, consistency in the petroleum summary report, and incorporating changes agreed to into the CMP. Meghan Dooley
6/27/2008 Exposure Tracking Model Ranking Initial ranking with ETM completed. Evonne Reese
8/18/2008 Update or Other Action Final 2007 Annual Groundwater Monitoring Report received. Navy recommendations are to add an additional location for product thickness measurements, named 12-184. Location 12-194 was added in 2007 to sample DRO on odd years. All other sampling will continue as prescribed. Meghan Dooley
3/20/2009 Update or Other Action Draft 2008 Annual Groundwater Monitoring Report received. Meghan Dooley
5/20/2009 Update or Other Action ADEC comments sent for 2008 Annual Groundwater Monitoring Report. Concerns include: increasing concentrations of contaminants at several sites and the adequacy of the MNA remedy at these sites, data consistency regarding an increase in oil seepage into East Canal not included in monthly reports. DEC is also concerned about destroyed monitoring wells and the possibility that they are not being replaced if essential to meeting objectives. ADEC recommends that the navy inventory all wells required for annual monitoring, properly decommission un-needed wells, and secure those where monitoring is necessary. ADEC also recommends that for those sites showing a trend increase, an evaluation should be performed in order to determine if additional action is necessary. Meghan Dooley
8/21/2009 Update or Other Action Final 2008 Annual Groundwater monitoring Report received. Navy recommends discontinuing monitoring activities at site as it has met DRO concentration endpoint criteria for two consecutive years. The site has met criteria for limited groundwater remedy. ADEC concurs with cessation of monitoring at this site. Meghan Dooley

5/12/2011 Document, Report, or Work plan Review - other The Final 2010 Institutional Controls Site Inspection Report was received by ADEC. The ICs appear to be functioning as intended for this site. Meghan Dooley
6/27/2011 CERCLA ROD Periodic Review The draft Third 5-Year Review was received. The purpose of the 5-Year Review is to evaluate the effectiveness of the remedy and determine if further action is warranted to protect human health and the environment. The document listed actions taken to address issues from the previous 5-Year Review, and offered new recommendations based on data collected from 2006 to 2010 from Operable Units A and B-1. It concluded that the remedy is functioning as intended at all but 4 sites and provided the following area-wide recommendations: 1. Update the current Comprehensive Monitoring Plan, Institutional Control Monitoring Plan, Operation and maintenance Plan, 2. Update the document repositories, 3. Assess and update as necessary the Community Relations Plan, and 4. Address action items identified during 2010 site inspections. Meghan Dooley
6/4/2013 Institutional Control Periodic Reporting The 2012 Final Institutional Controls Site Inspection Report was received. There were no indications of groundwater use, changes in land use, or unauthorized excavations. Excavation restriction signs were clearly visible. ICs appear to be functioning as intended. Meghan Dooley
9/10/2014 Institutional Control Periodic Reporting Received the Final 2013 Institutional Control Site Inspection Report. There were no indications of groundwater use, changes in land use, or unauthorized excavations. Excavation restriction signs were clearly visible. ICs appear to be functioning as intended. IC inspection frequency has been reduced to every 4 or 6 years (to coincide with the 5-year review). Guy Warren
3/16/2015 Update or Other Action Received Final 2014 Institutional Controls Site Inspection Report, OUA and OUB of the former Adak Naval Complex. No recommendations for site in report, as all IC’s appear to be functioning as intended. Next IC inspection is scheduled to occur in 2019 in coordination with the 5-year review. Guy Warren
3/6/2020 Institutional Control Periodic Reporting The U.S. Navy (Navy) is the lead agency and responsible party for monitoring and ensuring the effectiveness of the institutional controls (ICs) selected in the Operable Unit (OU) A Record of Decision (ROD) and the OU B-1 ROD at the Former Naval Complex, Adak, Alaska. The Navy is required to conduct monitoring for as long as site conditions pose an unacceptable risk for unlimited use and unrestricted exposure to the community and the environment. The ICs will remain in place until those conditions are met. If any of the ICs are ineffective or if significant failures pose harmful risks to the community and the environment, the Navy is responsible for additional remedial actions. Repairs to ICs identified by periodic inspections will be conducted by the Navy approximately every 3 to 5 years, if needed. If severe or unusual failures of ICs are observed, the Navy will conduct additional emergency repairs at that time. Because it has been shown that ICs have generally remained effective since 2005, reductions to the monitoring program began in 2013. Currently, 28 sites are inspected biennially (including Parcel 4) with 39 sites (including 12 remote OU B-1 sites) inspected every 5 years. Darren Mulkey
