Comment on cleanup documents for this site.
The Big B Mini Mart site, located at 1611 canyon Road in Ellensburg, was a gas station and convenience store that began operating in the early 1970s.
In 1990, soil and groundwater contamination from diesel fuel was discovered during the replacement of an underground storage tank. The site was independently cleaned up, but contamination was still detected in groundwater in 2015. Since then, interim cleanups and studies for a full cleanup action plan have been completed.
There is now a new draft Cleanup Action Plan. The new Agreed Order is necessary to implent the Cleanup Action Plan.
