Jun. 25, 2020 REMINDER

It is time to reapply for your Construction Stormwater General Permit

The Construction Stormwater General Permit (CSWGP) requires permittees to reapply for permit coverage at least 180 days prior to the expiration date of the current permit (General Condition G8). If you have an active CSWGP, you must reapply for coverage by July 4, 2020.

If permittees fail to reapply for the CSWGP, permit coverage will terminate on December 31, 2020. If your permit is terminated and you discharge pollution to waters of the State, you will be in violation of the federal Clean Water Act and chapter 90.48 RCW. If you have already submitted a renewal application, please disregard this notice.

To determine whether a renewal application was submitted for a permit, please visit and search by entering the permit number or project name. Scroll down and a ‘draft’ application should appear in the list of search results (see ‘Permit Status’ column). Ecology will notify you if any additional information is required.
