Announcing the Public Comment Period and Hearings for the Draft Construction Stormwater General Permit
The Washington state department of ecology (ecology) proposes to revise and reissue the construction stormwater national pollutant discharge elimination system (NPDES) and state waste discharge general permit (permit). The current permit was issued December 1, 2010, and will expire on December 31, 2015. The draft permit and fact sheet are available for review and public comment from July 1 through August 10, 2015, at 12 midnight. Ecology will host six informational public workshops and one public hearing on the draft permit.
Purpose of the Permit: The proposed permit authorizes the discharge of stormwater and authorized nonstormwater associated with construction activity. The permit covers all areas of Washington state, except most tribal lands (the permit does cover most of the Puyallup Reservation).
The proposed construction stormwater general permit (CSWGP) limits the discharge of pollutants to surface waters under the authority of the Federal Water Pollution Control Act (33 U.S.C. 1251) and limits the discharge of pollutants to surface and groundwater under the authority of the State Water Pollution Control Act (chapter 90.48 RCW).
Applying for Coverage under the Permit: Facilities covered under the existing permit that reapply for permit coverage in 2015 will be covered under the new permit. New or unpermitted construction sites may obtain coverage under the CSWGP by submitting a complete notice of intent (permit coverage application) to ecology and satisfying all applicable public notice and State Environmental Policy Act requirements (WAC 173-226-200). The application is available online at
