Stormwater Structural Control Preliminary Draft Workshop

This virtual workshop will focus on the:

• Phase I, Structural Stormwater Controls
• Western WA Phase II Municipal Stormwater Permit, Stormwater Management for Priority Developed Areas

We will share our preliminary plans for these two sections, based on early input we have received from interested parties. There will be an opportunity to provide further input on the proposed scope of changes. 

Tips for participants:

• Register in advance.
• Join five minutes early.
• For unstable internet, you can join by phone audio. In the Zoom meeting, click the up arrow by the mute button to select.

Background

Municipal stormwater general permits cover discharges from municipal stormwater systems. These are systems run by public entities that are separated from sanitary sewer systems. Learn about our municipal stormwater general permits.

In developing the preliminary drafts for both Phase I SSC and the WWA Phase II retrofit approach, we considered early input on permit reissuance. We also relied on input received during conversations with the SSC Policy Advisory Committee (PAC); a committee made up of Phase I and Phase II permittees as well as environmental non-profit groups.

We are requesting informal comments on this proposed stormwater retrofit approach for Western WA Phase II Permit for the 2024 permit cycle. We are also providing a preliminary draft of the Phase I Municipal Stormwater Permit’s Structural Stormwater Control (SSC) permit section for informal comment.
