Ecology has received information that this property may pose 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.

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

Ecology’s purpose in conducting a Site Hazard Assessment (SHA) is to identify the hazardous substance(s) and environmental characteristics associated with the site. In addition, Ecology evaluates the potential threat to human health and the environment, assigning a rank from 1 to 5, with 1 being most hazardous and 5 being the least. The rank is relative to other assessed sites in Washington. An SHA was conducted at this site on June 3, 2015, and it was assigned the rank of 1.
