2024 Western Washington Ad Hoc Process

This web page serves as a resource page for participants in the 2024 Western Washington Ad Hoc Process. Moving forward, western Washington permittees and stakeholders can visit this site to learn about this effort, track dates and times, and get updates – including from the various Topic Group’s efforts. Participation is open to anyone.  This effort aims to produce a series of white papers on key permit-related topics of interest to inform Ecology’s permit reissuance development process.


In 2018, Western Washington Phase I and II permittees reached out to the Department of Ecology (Ecology), along with other interested groups, seeking to provide early input on the upcoming 2019 municipal stormwater permits. Permittees, environmental non-governmental organization (NGO) representatives, and other interested parties worked together to inform and influence Ecology as they updated the permits for reissuance. Ecology left the work to the so-called “Ad Hoc Process” and did not enter the process until the end. In May 2021, Ecology staff reached out to see if there is interest in replicating the ad hoc process for the 2024 permit reissuances.  Since affirming interest, this effort is now underway.

If you are interested in attending the Plenary Meeting (agenda forthcoming) please contact Laurie Larson-Pugh.

WW Ad Hoc Plenary (virtual) Meeting is scheduled for October 12, 2021, from 1-3 pm PST

To help serve as a resource in terms of developing the Topic Group white papers, the following are copies of the white papers produced by Topic Groups during the previous Ad Hoc Process for the 2019 permits.
