2018 Municipal National Pollutant Discharge Elimination System (NPDES) Stormwater Permit: Ad Hoc Group

Next Meeting - Sept 29th 9:00 - 12:00pm 
Where:  Tacoma Central Treatment Plant: Transmission Building

Call in Option: 1-888-850-4523   Code:  544766

During the Confluence meeting on September 7th we identified the need to convene one more time prior to submitting the Early Input forms from the Topic Groups by the end of September. Ecology acknowledged that it would be useful to gauge regional support on the suggested permit changes, which will be one of the main goals of this meeting.  More detailed information and directions located on the Ad Hoc page.

The Western Washington Phase I and Phase II permits expire on July 31, 2018. The Washington Department of Ecology will be able to provide feedback and an update on the process going forward. Discussion among stakeholders will follow, and the Ad Hoc Topic Group members will use input from the meeting to draft up Early Input Submittal Forms to Ecology for each of the topic groups.
