Ecology received information that this property posed a threat to human health or the environment. This information may have come to Ecology from the owner of the property making a required notification, or may have come in the form of a complaint, through the Environmental Report Tracking System. During removal of a 6,000-gallon underground gasoline tank, soil cleanup was successfully documented; however, results of ground water sampling indicated the presence of benzene at concentrations above Model Toxics Control Act (MTCA) cleanup levels in one monitoring well.  Additional ground water monitoring wells were installed in 2016, and samples collected from these wells in June and October 2016 documented that benzene levels were below MTCA cleanup levels.


The Model Toxics Control Act (MTCA) mandates that Ecology track any site that is suspected or confirmed to be contaminated with hazardous materials. This property was listed on the Confirmed and Suspected Contaminated Sites List.


Ecology’s purpose in conducting a Site Hazard Assessment (SHA) is to confirm or rule out the presence of hazardous materials on site. The hazardous substance(s) and environmental characteristics associated with the site are identified, and Ecology evaluates the potential threat to human health and the environment. The site is either assigned a rank from 1 to 5, with 1 being most hazardous and 5 being the least, or given a No Further Action (NFA).


An SHA was conducted at this site on December 30, 2016 and Ecology concluded the site poses no significant threat to human health and the environment. The site status has been updated to NFA.
This site meets the eligibility criteria for Groundwater Model Remedy 1, as defined in Ecology Publication No. 16-09-057.
