Comments due by November 30, 2006

The Oregon Department of Environmental Quality (DEQ) is proposing the approval and implementation of a closure plan for the petroleum-contaminated site, Sisters Chevron, at 462 West Cascade Avenue in Sisters, Oregon. 

Petroleum contamination was discovered in 2005 when the underground storage tanks (USTs) and associated piping, were being decommissioned. The owner of the facility, American Energy, located in Bend, Oregon has conducted a cleanup at the facility, which included the excavation and disposal of approximately 1,160 tons of petroleum contaminated soil. An investigation was then performed to determine the magnitude and extent of any remaining contamination.

On May 16, 2006, DEQ received a report from the owner summarizing the environmental work performed to date and an evaluation of the risk associated with the remaining contamination. DEQ required additional information and on August 30, 2006, received the final documentation necessary to evaluate the cleanup report and closure proposal. Based on its review of the documentation, DEQ is recommending that the site be closed and granted a No Further Action status. Given the current and reasonably likely future land use, DEQ is recommending the utilization of vapor barriers, passive ventilation or similar measures as part of any future construction plans that include a residential component.

The proposed closure plan and related documents are available for review at DEQ’s Bend office, 2146 NE 4th Street, Bend, OR 97701. Appointments to schedule a review can be made by calling (541) 388-6146. Office hours are 8 a.m. to noon and 1 to 5 p.m., Monday through Friday. Questions and comments about the site should be directed to Joe Klemz in the DEQ Bend office, (541) 388-6146, ext. 237.

Written comments must be received by 5 p.m., Thursday, November 30, 2006 and directed to DEQ Project Manager Joe Klemz, DEQ Bend Office, 2146 NE 4th St., #104, Bend, OR 97701, or
