Toxics Cleanup Program

Eastern Washington Clean Sites Initiative 

Ecology’s Toxics Cleanup Program (TCP) has been identifying and cleaning up contaminated sites in Eastern Washington through the Model Toxics Control Act for many years.  As this work continues, new resources allow Ecology to focus additional efforts to clean up and restore sites in Eastern Washington. 

Through the Eastern Washington Clean Sites Initiative (CSI), the Washington Legislature and the Governor have committed the resources and funding for healthier communities.  The money comes from the state’s voter-approved tax on hazardous substances.

The Eastern Washington Clean Sites Initiative involves communities and other partners in shaping cleanup projects that improve local residents’ quality of life.  Funds will be used to clean up properties where the responsible party (land user, facility operator or property owner) could not be found or can’t pay cleanup costs.

These sites range from old gas stations where fuel leaked into groundwater, to former mining areas contaminated by cyanide, mercury and other metals.

The Community-Based Approach

The initiative is a community-based effort that fits Ecology’s priority to “reduce toxic threats” to people and the environment.  Ecology chose communities where sites are concentrated, so cleanup work can produce a number of benefits with minimal costs.  Read more about these sites by clicking on the site links.

How Can I Get Involved?

Many Washington residents are interested in a healthy environment and healthy communities, not just the residents of those communities.  Ecology invites all interested citizens to become involved in these cleanups.  The web pages for each site provide information on public involvement opportunities.
