Washington State's Water Quality Assessment for 2010

Ecology’s 2010 water quality assessment (WQA) will be an assessment of all marine water data received by October 15, 2009. The result will be the 2010 candidate 303(d) list for marine waters, which Ecology will submit to the Environmental Protection Agency (EPA) for approval.

The 2010 assessment of marine waters will be based on the most recent state water quality standards approved by EPA (Chapter 175-201A WAC, 2006 version and Chapter 173-204 WAC) and the state’s assessment policies:

• Program Policy 1-11, Chapter 1, Assessment of Water Quality for the Clean Water Act Sections 303(d) and 305(b) Integrated Report.
• Program Policy 1-11, Chapter 2, Ensuring Credible Data for Water Quality Management.

These guidance policies are available on Ecology’s website at http://www.ecy.wa.gov/programs/wq/303d/policy1-11Rev.html.
