Problems/Comments

Fuel Management Area. Active diesel and JP-4 fuel lines and storage tanks. Tank 7 has been removed. TCE and PCE also detected in the area. Groundwater pathway to ocean. This site consists of tank farms and underground pipelines, many of which have been abandoned in place. Eareckson AS is situated on Shemya Island, approximately 1,500 miles southwest of Anchorage, Alaska at the westernmost tip of the Aleutian Islands. Shemya Island is part of the Near Islands group of the Aleutian Archipelago. Shemya Island is owned by the U.S. Government and is under the jurisdiction of the United States Fish and Wildlife Service (USFWS) as part of the Alaska Maritime National Wildlife Refuge. The U.S. Army first developed facilities on Shemya Island in 1943 to support operations against the Japanese occupation forces on the nearby islands of Attu, Agattu, and Kiska. In 1954, the site was deactivated, and was turned over to the Civil Aeronautics Authority in 1955. In 1958, the Air Force returned to Shemya Island to support various Air Force and Army strategic intelligence gathering activities. It has remained active in this capacity to the present. In 1995, the station was downsized and reverted to caretaker status and a private operation and maintenance contractor took control of the facility under contract to the Air Force. Longitude is east of Greenwich. RCRA EPA ID#s AK9570028705 Hazardous waste activity: generator 2, storer and burns hazardous waste fuel in burner. AK7570000151 Cleanup. Hazardous waste activity: generator 1 and transporter. Also Huffman Construction Co. of Alaska RCRA EPA ID#AKD982654238 Hazardous Waste Activity: generator 2 at Shemya Air Force Base.

4/30/2008 Update or Other Action File number assigned: 2649.38.042. Nicole Hurt
5/6/2008 Update or Other Action ADEC staff issued a letter to the USAF regarding the submission of a Remedial Investigation Work Plan that does not address all of the site characterization information required by the state. It is the recommendation of the ADEC that a more comprehensive remedial investigation be conducted to collect a sufficient amount of information to characterize the subsurface contamination at each of the 12 sites in question. Jonathan Schick
7/11/2008 Site Characterization Workplan Approved ADEC staff approved the Remedial Field Investigation Work Plan for 12 sites including ST050. Jonathan Schick
12/9/2008 Update or Other Action ADEC Staff issued a letter to the 611th indicating that the Work plan Addendum for 6 sites at Eareckson AS would not be approved. We are not able to approve this Work plan Addendum at this time because of the one day turnaround time and the lack of information provided to render decisions applicable to this sampling program. Upon reviewing this document several questions arise about the proposed field activities. Without having an opportunity to review the data collected from the Remedial Field Investigation performed this summer, we cannot determine the appropriateness or comprehensiveness of the proposed sampling strategy. Therefore, by proceeding with this Work plan Addendum without the ADEC’s approval, there is a chance that we will not concur with the conclusions and recommendations derived from this Remedial Field Investigation. Jonathan Schick
3/26/2009 Update or Other Action ADEC staff recieved a draft version of the Analytical Data Report for the 12-site Remedial Investigation at Eareckson AS. A Draft Risk ASsessment Work Plan was submitted at the same time for our review. Jonathan Schick

The purpose of the RFI was to gather additional information about the 12 subject sites in order to support a Risk Assessment. Additional Site characterization will be necessary at SS12 where the PCB contamination extends beyond the bounds of the 2008 investigation. Jonathan Schick
8/25/2009 Update or Other Action ADEC staff submitted comments on the Draft Remedial Field Investigation Report for 12 SItes at Eareckson AS. The report detailed the results of the investigation that took place in 2008. THe State's concerns are regarding the incomplete characterization of the PCB contamination at SS12 adn some inconsistencies between the Work Plan and the Field Investiagtion including some subsurface sampling that was excluded from the RFI. Jonathan Schick
6/11/2010 CERCLA RI Report Approved Contaminated Sites Staff recieved the Final version of the Remdieal Investigation Report for the Remedial Field Inestigation at 12 Environmental Restoration Program Sites dated June 2010. Jonathan Schick
7/29/2010 Update or Other Action ADEC submitted comments on the Draft Remedial Field Investigation at 12 Environmental Restoration Program Sites (Addendum) which included an island wide background metals sampling event. The State;s main concern with the report is the statistical analysis of the background metals as the 95% UCL was used as the background concentration instead of the UPL or UTL. Additionally the report detailed the follow-on remedial investigation of the PCB impacts at SS012. Jonathan Schick
11/3/2010 Site Characterization Report Approved Contaminated Sites Staff issued a letter to the USAF approving the Final version of the Remedial Field Investigation at 12 Environmental Restoration Program Sites Remedial Investigaion Report Addendum. The report detailed the additional investigation of the extent of PCB impacted soils at SS012 the Old White Alice Site at Eareckson Air Station. Samples were collected around the perimeter of the previous investigations and also down the slope that drops from the site to the north/northwest. Also the addendum detailed the collection and calculation of background metals concentration from across the island at locations not associated with known contaminated sites. Jonathan Schick
