You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.


Summary

On August 5, 2015, the EPA Administrator signed a final rule updating six key areas of the federal water quality standards regulation which helps implement the Clean Water Act. The final rule was published in the Federal Register on August 21, 2015 (80 FR 51019).  The final revisions provide a better-defined pathway for states and authorized tribes to improve water quality, protect high quality waters, increase transparency and enhance opportunities for meaningful public engagement at the state, tribal and local levels. The previous regulation had been in place since 1983. 

Final Revisions

The following key program areas are addressed in the final rule: (1) the EPA Administrator's determinations that new or revised water quality standards are necessary, (2) designated uses for water bodies, (3) triennial reviews of state and tribal WQS, (4) antidegradation requirements, (5) WQS variances, and (6) provisions authorizing the use of schedules of compliance for water quality-based effluent limits (WQBELs) in NPDES permits.  The docket for this rulemaking is available at Docket ID No. EPA-HQ-OW-2010-0606

Ongoing Outreach

EPA intends to hold public webinars to discuss the contents of the final rule. As details become available, this section will be updated.

  • 2010 Listening Sessions

    In August 2010, as the Agency began work on the proposal, the EPA held two informal public listening sessions via audio teleconference to inform the public about the rulemaking, and to receive views on clarifications to the water quality standards regulation that were under consideration. The sessions provided a review of the EPA’s current regulation and a summary of the clarifications that the EPA is considering with time allotted for questions and comments. The agenda and resource materials were identical for both sessions.
