Publication Summary

In Washington State, contaminated sites may be cleaned up (remediated) using one of two processes; the formal process or the independent cleanup process. The formal process requires an order or consent decree and direct oversight by the Department of Ecology. Once a site has entered into the formal process, the provisions in the order or consent decree take precedence over any guidance in this document. The independent process was established to allow owners of contaminated sites to proceed with remediation of the site independent of Ecology's direct involvement. This guidance document was written for owners who wish to remediate their sites using the independent process. This document is obsolete and is being revised.
