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.

Problems/Comments

Former aboveground storage tanks (ASTs), 10-Meter Antenna #1, and Transformer Pad. AT&T Alascom site is located in a light industrial area. AST area soil samples and one groundwater (GW) sample indicates impacts by diesel range organics (DRO). Groundwater encountered at depths ranging from 6 inches to 3 feet below ground surface. Transformer Pad area soil tests at 6 inches below ground surface did not indicate polychlorinated biphenyls (PCBs). Soils on site under biovent remediation from a 1991 underground storage tank (UST) removal. Area is served by City of Kodiak water and sewer system. No known wells or critical habitats were reported. Groundwater not used as a drinking water source in Kodiak. The Phase II report showed no PCB contamination above detection limiits. The former ASTs - AOIA showed DRO contamination exceeding ADEC Cleanup levels. This is the only area requiring additonal assessment and remediation. Also see Alascom Earth Station - Kodiak 1991250031101 in the UST database. Diesel range organics contaminated soil remaiing under the building. Analytical data showed the bio-pile met cleanup standards. Bio-pile dismantled in 2005, with the liner and piping being disposed of at the Kodiak Landfill. Contaminated soil excavated during 2005 is temporarily stockpiled on-site awaiting a decision on remediation technology.

Action Information

Action Date Action Description DEC Staff
1/13/2000 Site Characterization Report Approved Phase II Site Investigation Report Received. The report documented soil and groundwater contamination exceeding ADEC cleanup standards for Diesel Range Organics and petroleum hydrocarbons. No PCBs were found in the soil above detection limits. The contaminants of concern at this site are petroleum hydrocarbons, specifically DRO. Additional remediation will be required to address the soil and groundwater contamination. Donald Seagren
6/23/2000 Site Added to Database DRO and possible PCBs. Bruce Wanstall
10/2/2000 Site Ranked Using the AHRM GW impacted but not an area DW source. Bruce Wanstall
2/27/2003 Update or Other Action Responsible Party field changed based on new information from PacificCorp Environmental Remediation Company. Elizabeth Stergiou
1/3/2005 Update or Other Action The file for this site was apparently lost in transferring between project managers and offices. A letter was sent to AT&T requesting copies of their entire file for this site. If it has not been done, additional site assessment &/or remediation is required to address petroleum contamination to soil and groundwater at the site. Donald Seagren
1/3/2005 Site Number Identifier Changed The site was originally thought to have possible PCB soil contamination when the site was initially entered into the CS DB, hence the 09 Workplan in the reckey number. A Phase II Site Investigation Report shows that no PCBs above detection limits were found. DRO/petroleum hydrocarbons are the only COC. The Workplan was changed from 09 to 01 because after review of site characterization reports, there are no hazardous substances reported at this site above cleanup levels. Donald Seagren
1/3/2005 Update or Other Action File number 2601.38.077 assigned and entered into the Fileroom database and Contaminated Sites database. Alyce Hughey
1/3/2005 Site Number Identifier Changed Changed the Spill Date from 1/13/2000 to 3/11/1995. Donald Seagren
2/17/2005 Update or Other Action Reviewed supplemental historic information missing from ADEC files that was supplied by consultant. Provided comments for development of work plan. Donald Seagren
4/26/2005 Cleanup Plan Approved Paul Horwath
7/27/2005 GIS Position Updated Using Figure 1.2 from a Phase II Site Investigation, Kodiak Earth Station, from Woodward-Clyde, dated December 29, 1997, in conjunction with TopoZone Pro, entered the coordinates for this site. Metadata include USGS Topo Map 1:63K, TopoZone Pro Street Map, on a Medium Size Map, View Scale 1:48,000, Coordinate Datum NAD83. Medium degree of confidence in accuracy of location. Alyce Hughey
9/12/2005 Cleanup Plan Approved Approved the Cleanup Plan. Informed AT&T Consultant on the status of approval for the soil remediation facility on Kodiak Island. Donald Seagren

9/14/2007 Update or Other Action Telephone call from Alex Tula. Due to changes in scheduling for USCG soils, the Kodiak soils will not be shipped off island this year. He will conduct an inspection and and make sure the stockpile is still covered. He will make any necessary repairs to the cover/liner. ALTA will request a variance until the summer of 08 for removal of the soils off the island for treatment. Donald Seagren
12/11/2007 Update or Other Action Approved request for a one year extension for transporting the 250 yds3 contaminated soil stockpile off the island for disposal. The shipment of thses soils is being coordinated with a similar shipment from the USCG Kodiak base as a cost savings measure. The stockpile remains covered and in good shape. There are no concers to human health or the environment by leaving this stockpile on-site until the summer of 2008. Donald Seagren
6/12/2008 Update or Other Action Site transferred from Don Seagren to Paul Horwath per Linda Nuechterlein. Alyce Hughey
9/2/2008 Offsite Soil or Groundwater Disposal Approved 450 cubic yards of soil was transported to Columbia Ridge Landfill in Washington State. Paul Horwath
