Cleanup Complete
Ecology removed the site from the Hazardous Sites List in 2012, following cleanup.
The site used to house a meter station that regulated natural gas distribution to local customers. In 1990, a site assessment found mercury in soil at levels requiring cleanup outside the meter station. The contamination was most likely from mercury leaking from equipment during maintenance.
Three drums of gravel and soil were removed from under and around the former meter stand and work desk. Nearly 49 tons of soil were disposed at a landfill. Follow-up sampling showed all contaminated soil was removed.
