Interim Removal Action Approved |
Letter sent to Norm Straub of AKARNG with approval of interim removal action plan (with addendum) prepared by Clearwater The plan describes procedures to conduct an interim removal action in accordance with 18 AAC 75.330. ADEC determined that the proposed interim removal action will reduce human and environmental exposure to hazardous substances at the site and help to prevent the migration of hazardous substances from the site to groundwater and surface water. Up to twenty cubic yards of petroleum-contaminated soil will be excavated and placed in 55-gallon steel drums or 1-cubic yard Supersacks for temporary storage onsite in an area lined with 10-mill polyethylene plastic. The drums or Supersacks will also be covered with a 6-mill polyethylene plastic cover. The contractor intends to transport the contaminated soil via barge to Seattle, Washington and then via highway to a thermal desorption treatment facility located in Lakewood, Washington. Prior to transporting the contaminated soil from the Saint Mary's Federal Scout Armory site, the Alaska Army National Guard contractor will obtain written ADEC approval to move the soil in accordance with 18 AAC 75.370 (b). |

Interim Removal Action Approved |
The Interim Removal Action report for the Alaska Army National site in St. Mary's was approved. The report documents that 22.3 tons of petroleum contaminated soil were removed and treated at TPS Technologies in Washington. Diesel range organics (DRO) were found up to 20,200 mg/kg remaining in the southern sidewall of the excavation. Because residual petroleum contamination in soil, for five of six confirmation samples, exceeds 18 AAC 75.341 Table B1 migration to groundwater cleanup levels, additional site characterization and/or cleanup are necessary. |

Site Characterization Report Approved |
The Secondary Site Characterization, Federal Scout Armory, St. Mary’s Alaska, December 2008 was reviewed.
The report documents many areas that meet cleanup levels, but does not appear to have accurately delineated where contamination remains at the Armory.
DEC is concerned that the report notes about 2000 cubic yards of potentially contaminated soil was removed to place underground utilities. Please contact the appropriate person(s) in St. Mary’s to determine what, if any, characterization of the soil took place and to determine where this soil is currently located. DEC would like this information by May 1, 2009.
