Stormwater and TMDLs

Interagency Project

Implementation of Clean Water Act programs to assess waters for impairment and develop cleanup plans (TMDLs) pose substantial administrative, technical, financial, and legal challenges for federal, state, and local agencies as well as stakeholders. Recognizing these challenges, an Interagency Team formed in 2012 to discuss approaches and recommend improvements to Water Quality Assessment (WQA) and TMDL programs in Washington State.

The Interagency Team consists of stormwater professionals from local municipalities and WSDOT).
The Interagency Project Team compared the WQA and TMDL programs in Washington State to five other states in order to identify potential improvements. The objectives of the project were to:
  1. Learn alternative approaches for CWA programs from other states,
  2. Utilize the research to develop recommendations for improving Washington State’s WQA, listing/de-listing, and TMDL procedures, and
  3. Work with EPA and Ecology to refine and implement many of the recommended improvements.
A report, titled Recommendations for Improving Water Quality Assessment and Total Maximum Daily Load Programs in Washington State , was finalized in July 2014.  The report summarizes methods used to “compare and contrast” Washington’s WQA and TMDL programs with five other states, key findings, and recommendations.

The report has served as a starting point for discussions with Ecology and EPA regarding improvements in the state’s WQA and TMDL programs.  The Team plans to continue discussions and effort toward program improvement.
