Problems/Comments

The Atka Cape Kudugnak Formerly Used Defense Site (FUDS) (CERCLIS ID Number AKN001002630), which began operation on March 2, 1943 as a U.S. Naval radio station used to support air operations at the former Atka Air Force Auxiliary Field during World War II, was evaluated by the Environmental Protection Agency (EPA). The following contaminants were found above ADEC cleanup levels: Antimony, Arsenic, Chromium, Diesel Range Organics, Lead, Mercury, Methylene Chloride, and Polychlorinated Biphenyls. The site consists of numerous surface drums, a transformer, two 2,000-gallon empty aboveground storage tank, a transformer, out-buildings, six automotive batteries, and four collapsed radio towers.

Action Information

4/4/2014 CERCLA SI Submit comments to USACE and contractors on the Draft Site Investigation Work Plan for Atka Cape Kudugnak FUDS site. The Work Plan identified BDDR, Con-HTRW, and HTRW activities that will occur during the summer of 2014. Comments focused on appropriate analytical procedures and sampling requirements. Guy Warren
6/2/2014 CERCLA SI Receive Final BDDR, CON/HTRW removal, and SI work plan for the Atka Cape Kudugnak FUDS. Submit approval letter to USACE. All comments ADEC had submitted were addressed. Project consists of removal of buildings, drums, AST's, transformers and other material that poses a potential environmental threat. Soil contamination, if encountered, will be excavated and any contamination remaining at the site will be adequately characterized. Guy Warren
1/6/2016 Update or Other Action ADEC received the Draft Final BD/DR, CON/HTRW Removal, and SI Report for Atka Cape Kudugnak FUDS on December 9, 2015. ADEC provided comments on January 6, 2016 and all comments were addressed. ADEC is presently waiting on the final version for approval. Based on the results from the BD/DR, Con/HTRW, and SI at the site, BSI-TLI JV (consultant) concludes that the site should be considered for closure with Cleanup Complete. Holly Weiss-Racine
7/8/2016 Report or Workplan Review - Other The USACE provided ADEC with the “Draft 2016 Work Plan Addendum” to address residual soil contamination at a lakeside drum cluster site on July 5, 2016. ADEC provided comments to the work plan addendum on July 8, 2016. During the previous CON/HTRW project, a drum cluster was removed and a soil sample collected from beneath the drums produced a DRO result of 60,000 mg/kg. This area will be excavated and soil will be removed and treated. Work is proposed for August 2016. Holly Weiss-Racine
7/14/2016 Report or Workplan Review - Other The Final BD/DR CON/HTRW Removal and Site Inspection Report was received and approved by ADEC on July 14, 2016. Additional work includes soil excavation at the drum cluster to be addressed in the 2016 Work Plan Addendum. the East Radio Site and West Barracks Site are recommended for closure. Holly Weiss-Racine
3/24/2017 Report or Workplan Review - Other The work at Cape Kudugnak scheduled for 2016 was postponed until 2017 due to unavailability of equipment and lodging during the scheduled work timeframe. ADEC received an update, Cape Kudugnak Drum Cluster CON/HTRW Work Plan Addendum Update, dated 3-22-2017. The updates to the approved 2016 Work Plan were administrative changes and do not change the scope of the approved 2016 Work Plan. The field work is currently scheduled for April 2017. Darren Mulkey
4/3/2017 Report or Workplan Review - Other Reviewed the Cape Kudugnak Drum Cluster CON/HTRW Work Plan Addendum Update dated March 22, 2017. Subsequently we met with USACE FUDS in the ADEC office on March 30, 2017. We have reviewed the August 2016, Final Work Plan Addendum, Cape Kudugnak Drum Cluster CON/HTRW, that was previously approved by ADEC. We conclude that the March 22, 2017 Cape Kudugnak Drum Cluster CON/HTRW Work Plan Addendum Update does not present any substantive changes to the previously approved August 2016, Final Work Plan Addendum, Cape Kudugnak Drum Cluster CON/HTRW. The Cape Kudugnak Drum Cluster CON/HTRW Work Plan Addendum Update dated March 22, 2017 is accepted and the August 2016, Final Work Plan Addendum, Cape Kudugnak Drum Cluster CON/HTRW is still approved for the work scheduled in 2017.

11/6/2017 CERCLA Removal Action Report Field work was conducted in Spring 2017 in accordance with the Final Cape Kudugnak Drum Cluster CON/HTRW Work Plan Addendum. The work plan addendum amended the Final BD/DR, CON/HTRW Removal, and SI Work Plan, developed for similar work conducted at the Cape Kudugnak Naval Radio Station in 2014 and 2015. The primary objective was the removal of drums and all significant soil contamination (within contract that may be acting as a future contamination source. BSI-TLI JV located the former drum cluster and delineated the surrounding contaminated soil (source of contamination) with field screening methods. A total of 26.1 tons of the most contaminated soil was excavated from the delineated area, containerized, and barged offsite for compliant disposal at a Subtitle D landfill in Oregon. No discarded drums were encountered during the removal action. Analytical data from confirmation soil samples collected from the excavation sidewalls and floor showed that diesel-range organic (DRO)-contaminated soil remains at the work site at concentrations up to 7,620 milligrams per kilogram (mg/kg) which exceeds the ADEC Method Two Migration to Groundwater cleanup level of 230 mg/kg. Gasoline-range organics and residual-range organics were not detected or were detected at concentrations less than corresponding Method Two cleanup levels. Darren Mulkey
