The Department of Ecology completed Washington State’s Water Quality Assessment for 2002/2004. Ecology submitted the Water Quality Assessment to EPA on June 2, 2005, as an “integrated report” to meet the Clean Water Act requirements of sections 305(b) and 303(d). EPA approved Category 5 of the 2004 Water Quality Assessment (PDF) on November 4, 2005. Category 5 represents the state’s 303(d) list of impaired waters.
Ecology worked with EPA to correct errors in the candidate submittal. As a result, several listings moved between categories. Please see our 2004 Water Quality Assessment Errata Table (PDF) to review these changes.
