AZPDES Permittees and the Navigable Waters Rule

The new WOTUS rule and your AZPDES Permit

As of today, the Waters of the US/Navigable Waters Rule will become effective on June 22. ADEQ has been working to prepare for the rule change and to provide answers to your questions posed during the initial meeting on March 24.

On June 15, ADEQ will provide information regarding permit status and the termination process for those no longer discharging to Waters of the U.S. after the rule effective date. We will also provide updates on several programs underway including determining Traditionally Navigable Waters, methodology for a typical year analysis, development of a state-wide flow regime map and information provided by the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. Lastly, we will provide an update on what we know about legal challenges to the rule and the status of those cases.

Date: Monday, June 15, 2020 Time: 1 p.m. – 3 p.m. Location: Online Only
