We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


In 2010, during the construction of the Chemical Storage Building, petroleum-impacted soil was encountered off the SW corner. Some contaminated soil was excavated and removed from site. Confirmation Soil samples collected from the excavation contained DRO up to 4,420 mg/kg. The source of contamination is unknown.

11/22/2010 Exposure Tracking Model Ranking Initial ranking with ETM completed for source area id: 78977 name: Historic Petroleum - Unknown Source Grant Lidren
12/1/2010 Offsite Soil or Groundwater Disposal Approved In the absence of Grant Lidren, project manager for the site, to expedite the transport of a 70 c.y. contaminated soil stockpile, reviewed the TestAmerica lab analytical results for 8 samples that were analytzed for GRO, DRO, RRO, PAHs, VOCs (including BTEX), and TLCP Metals. Only DRO exceeded the migration to GW cleanup levels but were below the ingestion/dermal contact cleanup levels. As a result, processed a "Contaminated Soil Transport and Treatment Approval Form" to move the 70 c.y. from adjacent to the excavation to a co-mingled stockpile of like contaminated soils at Pad 172 for later treatment.

7/26/2011 Report or Workplan Review - Other On this date, ADEC reviewed Kodiak Chemical Storage Facility Contaminated Soils Report, submitted by EMI, dated December 20, 2010. During construction of a new Chemical Storage Building, EMI was contracted to evaluate contamination discovered off the SW corner of the building footprint. Based off screening and visual/ olfactory senses, 70 cy of contaminated soil was removed plus 15 cy of clean material from an excavation 28’ by 28’ by 3’. The 15 cy stockpile of clean soil was added to a previous 750 cy stockpile of clean soil from the building footprint and transported offsite. Three soil samples collected from the 70 cy contaminated stockpile contained DRO up to 3,840 mg/kg. The contaminated 70 cy stockpile was hauled offsite to a landfarm operated by the US Coast Guard and comingled with other soils and land farmed. Four confirmation soil samples collected from the sidewalls and the base of the excavation contained DRO up to 4,420 mg/kg. To evaluate potential vertical extent of contamination a test pit was excavated from the highest screened location. At 10 ft. bgs, a faint odor and a screening level of 2.7 ppm was observed. Additionally, to evaluate potential contamination within the building footprint, 38 screening samples collected contained 0.0 ppm w/ no olfactory or visual presence of contamination. Grant Lidren
8/24/2011 Potentially Responsible Party/State Interest Letter On this date, ADEC sent a letter to the RP, USCG, notifying them that the management of the site has been transferred to the ADEC Federal Facilities Environmental Restoration Program. Grant Lidren
9/15/2016 Site Visit ADEC Contaminated Sites program staff conducted site visits and inspections of the contaminated sites which are located on the USCG Base Kodiak between September 15-16, 2016. Curtis Dunkin
