Announcing the Reissuance of the Sand and Gravel General Permit
On February 17, 2021, the Washington state department of ecology (ecology) reissued the sand and gravel national pollutant discharge elimination system and state waste discharge general permit (permit). The permit becomes effective on April 1, 2021, and expires on March 31, 2026.
Purpose of the Permit: The permit provides statewide coverage for facilities that engage in sand and gravel operations, rock quarries, similar mining operations, concrete batch operations, and hot mix asphalt operations. The sand and gravel general permit does not provide coverage to facilities that are covered under an individual permit that authorizes discharges from these activities. The purpose of the permit is to control the discharge of pollutants from process water, stormwater, and mine dewatering water associated with sand and gravel activities into waters of the state. Under federal and state water quality laws (Federal Clean Water Act and State Water Pollution Control Act), a permit is required for the discharge of these wastewaters.
Public Notice Process and Comments: Ecology accepted public comments on the draft permit, fact sheet, and related documents from October 27, 2020, through 11:59 p.m. on December 11, 2020. Ecology held two public workshops and hearings via online webinars on December 2, 2020, and December 4, 2020. Ecology received written comments during the public comment period. The comments and ecology's responses are included in Appendix A of the fact sheet.
Copies of the Permit: You may download copies of the final permit, fact sheet, response to comments, and other supporting documents online at You may also request copies from Kimberly Adams at or 360-407-6448.
Applying for Coverage under the Permit: Permitted facilities that have complied with the one hundred eighty day duty to reapply requirement, General Condition G20 in the current permit, will be covered under the new permit. New or unpermitted facilities may obtain coverage under the permit by submitting a complete permit application to ecology and satisfying all applicable public notice and State Environmental Policy Act requirements (WAC 173-226-200). Access to the application is available online at
