Problems/Comments

Gasoline contaminated soil remains beneath structures at the site above regulatory migration to groundwater soil cleanup levels. A Site Assessment Report dated August 1998 states that residual soil contamination had concentrations of benzene at 0.11 milligrams per kilogram (mg/kg) and gasoline range organics (GRO) at 810 mg/kg in the excavation after closure by removal of the leaking 1,000-gallon gasoline underground storage tank (UST). Fifteen cubic yards of contaminated soil was transported to an ADEC approved stockpile site at 102 Burkhart Street in Sitka. A monitoring well was installed to investigate groundwater contamination observed at 7 feet below grade in the UST excavation. Interim corrective action report dated October 1998 stated that the GRO concentration of 1,300 mg/kg in the contaminated soil stockpile was reduced to 5.8 mg/kg in 67 days as a result of tilling in the sun and covering the soil during periods of rain. A December 1998 remediation plan proposal reported that investigation trenching and soil field screening did not indicate any reduction in contamination of subsurface soil at the former UST site. As a result, ventilation piping was installed to assist remediating the residual soil contamination. The ADEC letter dated January 6, 1999 requested additional subsurface soil and groundwater investigation to collect samples and analyze them for GRO, benzene, toluene, ethylbenzene, and xylenes (BTEX) compounds and lead. The ventilation piping was approved for passive aeration only. The ADEC letter accepted the sampling and analysis results for the stockpiled remediated soil and approved the soil for off-site use in a non-sensitive or non-wetlands environment.

Action Information

Action Date Action Description DEC Staff
7/28/1998 Leaking Underground Storage Tank Release Confirmed - Petroleum LUST Site created in CSP for source area ID 77569 (Added by System) Former Staff
7/28/1998 Release Investigation Gasoline contaminated soil remains in-situ and groundwater at 7 ft. bgs is impacted. Awaiting DEC response to proposed corrective action plan to air sparge via PVC laterals. DEC needs further information regarding nature of soil so cleanup level can be set, potential for vapor to be blown into structure, layout of sparging pipe in relation to contamination, structure, and groundwater. Former Staff
7/28/1998 Site Added to Database Former Staff
7/28/1998 Leaking Underground Storage Tank Cleanup Initiated - Petroleum Closed by removal of 1,000 gal gasoline UST. Structure and underground utilities restricted ability to excavate all contaminated soil. 15 cyds of contaminated soil stockpiled at Bickar Property at 102 Burkhart St. Bruce Wanstall
12/1/1998 Leaking Underground Storage Tank Corrective Action Underway Monitoring well was nstalled and 1-inch perforated PVC laterals installed to assist with insitu bioremediation. LCAU via remediation of stockpiled soil via uncovering and tilling during non-rainy periods. Bruce Wanstall
10/2/2001 Update or Other Action Changed Project Manager from Paul Horwath to Bill Janes Cynthia Pring-Ham
12/19/2001 Update or Other Action Project tickler update - Sent Jason Ginter an email asking if a final report is available. Cannot tell from file if treatment was successful or if any other issues remain. Bill Janes
1/8/2002 Update or Other Action Telecon with Ginter - Test pit dug fall of 2000 approximately to check if insitu air sparge and fertilizer were doing the job. Jason determined that it needed more time to remediate and no samples were taken. Will go back soon and notify me of schedule. Bill Janes
3/4/2002 Update or Other Action Project tickler update - Sent a second email to Ginter asking if a date had been set for additional sampling Bill Janes
8/21/2002 Update or Other Action RECKEY has automatically been generated. Cynthia Pring-Ham
12/1/2006 Update or Other Action Project manager changed from Janes to Wanstall. Review file and correspondence for site status to request an update from the RP/consultant. Bruce Wanstall

12/20/2006 Exposure Tracking Model Ranking ETM Baseline Ranking performed 12/6/06. GW not used as a source of drinking water in Sitka but no formal institutional controls are known to be in place. No soil or GW data since passive air-sparge system installed. Additional data collection recommended. Site closure feasible. Daniel Fremgen
10/30/2007 Potentially Responsible Party/State Interest Letter ADEC reminded the operator of the Prewitt Funeral Home in Sitka, via certified letter, that we have received no response to our request for current site data concerning the gasoline release from a regulated underground storage tank at the facility.

5/4/2012 Document, Report, or Work plan Review - other DEC evaluated the 2012 Report by Chilkat Environmental received today. The conclusions in the report are that contamination levels are low and the pathways for human exposure are incomplete. Recommendations are that the UST excavation site be capped and the site closed. Bruce Wanstall
6/6/2012 Site Visit DEC inspected the exposed surface of the UST excavation site at the vehicle entrance bays on Kimsham Street. DEC met with the Prewitts to discuss the 2012 Report by Chilkat Environmental and the possible need for institutional controls in a cleanup complete determination. Bruce Wanstall
6/26/2012 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 77569 Gasoline UST. Bruce Wanstall
6/29/2012 Cleanup Complete Determination Issued The cleanup actions to date have served to excavate and adequately remove contaminated soil from the site. Based on the information available, DEC has determined no further assessment or cleanup action is required. There is no longer a risk to human health or the environment, and this site will be designated as closed on the Department's database. This determination is in accordance with 18 AAC 78.276(f) and does not preclude DEC from requiring additional assessment and/or cleanup action if future information indicates that this site may pose an unacceptable risk to human health or the environment.
