Letter to Air Force from ADEC RE: The October 20, 1998, closure of UST, AFID # 187OU, located at building 32-187 on Elmendorf AFB. Review of the site assessment report received December 16, 1998, prepared by ASRC Construction Company, Inc. Facility ID 0-001525, tank # 377.
The Department of Environmental Conservation (Department) has received and reviewed the site assessment report documenting the closure of the above mentioned regulated underground storage tank (UST). The report summarizes the information collected during closure of a 2000-gallon used oil UST and an adjacent oil/water separator. Based on the information and laboratory data presented in the report, it appears all the contaminated soil, above the required cleanup level for this site, has been removed from the excavation and is currently being stockpiled near the site.
Data presented in Table 4 of the site assessment report indicates confirmation sample, 87007SP, collected from the 40 cy soil stockpile, contained 64 ppm of PCBs. The Department has established a cleanup level of 10 ppm for PCBs in soil. Soil that has PCB contamination greater than the 10 ppm must undergo corrective action. In accordance to 18 AAC 78.250, the Department is requesting the Air Force to develop a corrective action plan to address the PCB contaminated soil stockpile. At a minimum, the plan should include the following items:
A map showing the location where the stockpiled soil is currently being stored.
Assurances that the stockpile is constructed of approved materials and designed to prevent water run-on and run-off in accordance to with 18 AAC 78.274.
A plan to either treat or properly dispose of the contaminated soil. |

Jennifer Roberts (DEC Federal Facilities) sent a letter to Joe Williamson dissolving the State Elmendorf Environmental Restoration Agreement. The Alaska Department of Environmental Conservation (DEC) has reviewed the issue of abolishing the State Elmendorf Environmental Restoration Agreement (SERA) per your recommendation. Elmendorf Air Force Base and DEC entered into the SERA in 1992. The agreement was developed as a tool to bring the Base into compliance with Alaska's regulations addressing underground storage tanks, oil and other hazardous substance releases and solid waste.
Since that time, Elmendorf has made significant progress in investigating and cleaning up historic contamination problems. Many of the sites covered by the SERA have been successfully cleaned up and closed. Cleanup is underway at the remaining sites. Additionally, Alaska has amended the regulations addressing fuel storage tanks, oil and other hazardous substance spills and solid waste. We concur with you that the SERA is no longer a necessary or beneficial. This letter serves as notice that DEC will end oversight on environmental work at Elmendorf by using the SERA. Instead, it is understood that the sites and programs formerly addressed by SERA: solid waste, underground storage tanks (UST), and oil and other hazardous substance discharges will be addressed in accordance with 18 AAC 60, 18 AAC 78 and 18 AAC 75. |
