Chevron 97348 Site

Proposed Removal from the Hazardous Sites List

March 28, 2019 - April 29, 2019

Ecology is proposing to remove the Chevron 97348 site, located at 500 and 510 North Wenatchee Avenue in Wenatchee from the Hazardous Sites List.  The Hazardous Sites List is a statewide list of contaminated properties.  The site is currently ranked a "2" on the list.  A rank of "1" is the highest level of concern compared to other sites on the list, and a rank of "5" is the lowest.

Ecology invites you to review the Fourth Quarter 2018 Groundwater Monitoring Report and Site Closure Request, dated December 27, 2018 and comment on the proposed removal from the Hazardous Sites List.

The site is a former Chevron fueling station that operated until 1990.  A gasoline release was reported in 1990.  In 1991, the buildings, fueling dispensers, lines and six underground storage tanks (USTs) were removed.  Soil and groundwater contamination was discovered.  Approximately 400 cubic yards of contaminated soil was removed and disposed of offsite.

Several groundwater monitoring events have occurred, with the most recent in 2018.  Four rounds of quarterly groundwater monitoring has shown that the cleanup has been successful and any remaining contamination was below state cleanup standards.  Therefore, Ecology has determined the site no longer poses a threat to human health or the environment and may be removed from the Hazardous Sites List.
