Industrial Stormwater General Permit reissuance process began with public listening sessions

The current Industrial Stormwater General Permit expires on Dec. 31, 2019. We are beginning the reissuance process with a series of public listening sessions to discuss potential changes to the permit. These meetings are a chance for you to learn more about the proposed changes to the permit and to ask Ecology staff any questions about permit coverage. Our proposed changes to the permit include:

  • Adding two new industry groups that require coverage
  • Adding language to protect groundwater
  • Changing the timing of First Flush
  • Revising requirements for Consistent Attainment

You can download a webinar version of a listening session.
