Initial Investigation

When Ecology learns about a release of a hazardous substance into the environment, we do an Initial Investigation. Release information may come to us through the Environmental Report Tracking System, either from the property owner making a required notification or as a complaint from someone who saw the release.


During the Initial Investigation, we evaluate environmental conditions at the property and review all available data. The goal of the Investigation is to determine if the release may pose a threat to human health or the environment, and if further cleanup actions are needed.  We track any site that is suspected or confirmed to be contaminated with hazardous materials, as required by the Model Toxics Control Act (MTCA).


No Further Action

Ecology has completed an Initial Investigation at this site, and has determined No Further Action is required due to independent remediation. We received documentation showing that a cleanup has occurred and there is no remaining contamination above the applicable state (Model Toxics Control Act Method A) cleanup levels.
