Problems/Comments
Diesel release from out-of-service buried oil tank. 10 cubic yards contaminated soil excavated and stockpiled off-site. Pit wall sample next to building had 4300ppm DRO. Residual contaminated soil beneath structure is esitmated at three cubic yards. The following year fresh diesel was found in the crawlspace of the building. Source of the release was tracked to a 300gallon fuel tank buried beneath 2 layers of sidewalk in the front yard. 50 gallons of diesel was recovered from the tank and 15 cubic yards of contaminated soil associated with the tank removal was stockpiled on-site. Lot A Burgess Estate Subdivision 10 yards contaminated soil in back yard removed by State Farm in 1993 was remediated in a biocell at Granite Creek in Sitka. New owner Northern Credit Services removed the second UST and 15 yards contaminated soil from the front yard. Sumps in the front (east) corners of the building are plumbed to french drain along south property line.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 5/10/1994 | Cleanup Plan Approved | Department approval sent by letter for an in-situ bio-remediation plan. Residual diesel soil contamination resulting from the underground fuel storage tank release near the east property boundary will be treated by distributing fertilizer around the original tank removal site and backfilling with clean shot rock material. | Bruce Wanstall |
| 2/23/1998 | Site Added to Database | Sally Schlichting | |
| 5/19/2000 | Site Ranked Using the AHRM | Scheduled follow-up testing on remaining contaminated soil left on-site unconfirmed. | Bruce Wanstall |
| 1/17/2001 | Update or Other Action | Telecon with Sharon Bergman, manager, who worked at the site for State Farm when the spill and subsequent tank removal occurred in 1993. The building is now occupied by Northern Credit Services Inc. | Bruce Wanstall |
| 12/13/2001 | Update or Other Action | Telecon with Steve Phillips, property owner: Steve related that USTs existed both in front and back of the building. Smith-Bayliss had conducted a thorough clean-up of the site that included removal of all soil that was attainable without risking the foundation of the building. | Bruce Wanstall |
| 8/19/2002 | Update or Other Action | Since the tenant change from State Farm to Northern Credit, the front yard where the spill occurred has been paved for parking. Sharon stated that some excavation was necessary for the paving and no contaminated soil was encountered. | Bruce Wanstall |
| 7/17/2003 | GIS Position Updated | Coordinates recorded on the property from GPS field unit. Transform for Nad27 (Topozone) use 57* 03' 15.23518" and -135* 20' 5.11990" coordinates. | Bruce Wanstall |
| 9/26/2007 | Exposure Tracking Model Ranking | Initial ranking with the ETM determined that the contaminated subsurface soil is the controlling pathway. The in-situ recovey and remediation plan was approved by the ADEC in 1993. The primary area of concern is currently paved with asphalt and no sheen or off-site migration was observed during the site inspection by ADEC in 2003. | Bruce Wanstall |
| 10/9/2007 | Institutional Control Record Established | Institutional controls limit, prohibit or protect against activities that interfere with improvements designed to encapsulate or control residual contamintion per 18 AAC 75.990(54). In that regard, any proposal to excavate the residual contaminated material shall be reported to ADEC and a work plan describing how the soil will be managed and/or disposed must be submitted for review and approval prior to excavation. | Bruce Wanstall |
| 10/9/2007 | Conditional Closure Approved | Contaminant concentrations remaining at the Lot A, Burgess Estate Subdivision property, known as the former State Farm Insurance building site, were evaluated with regard to the potential exposure pathways and ADEC determined they do not pose an unacceptable risk to human health or the environment. The residual diesel range hydrocarbon concentration in soil that remains on site will attenuate over time and site management controls are established. | Bruce Wanstall |
