Public workshops and hearings

Ecology is holding six informational workshops and public hearings. Four of these events are online, and two are in person. The dates, times, and formats of each event are provided below.

The purpose of the workshops is to explain the proposed changes to the draft permits and SWMMs, and to answer questions prior to the formal public hearings. The purpose of the hearings is to provide an opportunity for people to give formal oral testimony on the proposed draft permits and SWMMs. Oral testimony will receive the same consideration as written comments.

The public hearings will begin immediately following the public workshops and will conclude when public testimony is complete.
