Hazardous Sites List

The Department of Ecology publishes the Hazardous Sites List as required by WAC 173-340-330. The list includes all sites that have been assessed and ranked using the Washington Ranking Method, as well as National Priorities List sites.

Ecology updates the list twice a year. Because of budget constraints, the Hazardous Sites List will only be available online.

Please refer to the Hazardous Sites List for contact information regarding specific sites.

Environmental Covenants Registry (July 2008)

The Environmental Covenants Registry is a list of sites that have residual contamination remaining on them after the cleanup has been completed.  These sites have environmental covenants or deed restrictions limiting certain uses of the property.  Example covenants would be those prohibiting the drilling of a water supply well on the property or use of the property for residential uses.
