Construction Stormwater General Permit (CSWGP)

July 1, 2020 - Aug. 14, 2020, 12:59 p.m.

We invite you to comment on the draft Construction Stormwater General Permit. You can view the draft permit and related documents on the Construction Stormwater General Permit webpage.

Stormwater runoff from construction sites can carry muddy water, debris, and chemicals into local waterways. Sediments, chemicals, and debris can harm aquatic life and reduce water quality. This permit helps control and reduce water pollution from these activities.

Learn more about how following the requirements in this permit helps control and reduce water pollution.

While Washington's Stay Home, Stay Healthy coronavirus response order is in effect, we will not hold in-person public events and documents are available for review online only. If you need a hard copy document, please contact Dena Jaskar at dena.jaskar@ecy.wa.gov or 360-407-6401.
