Ecology Proposes Revisions to the State Standards to Respond to Disapproval by the EPA

The Department of Ecology adopted the revised State water quality standards in July 2003. On March 22, 2006 the U.S. Environmental Protection Agency (EPA) formally disapproved parts of Washington State’s 2003 water quality standards (see letter (PDF]). EPA determined that the standards did not go far enough to protect salmon and bull trout in certain streams and rivers.

Ecology proposed a new set of rules to fix the deficiencies identified by EPA in its disapproval of the state’s standards. As part of the process public hearings were held in five locations around the state August 7-15, 2006. A public comment period was held July 5 - September 5, 2006. Please see the following documents for more information on this rule-making process:
