Sand and Gravel General Permit
The Sand and Gravel General Permit regulates discharges of process water, stormwater, and water from mine dewatering into waters of the state associated with sand and gravel operations, rock quarries, and similar mining operations. The permit also covers concrete batch operations and hot mix asphalt operations. Untreated discharge water from sand and gravel operations may harm fish, aquatic life, and water quality. Ecology modified the permit on August 17, 2011.
The current Sand & Gravel General Permit expired October 1, 2015. We plan to revise and reissue the new permit on February 17, 2016 with an effective date of April 1, 2016.
We have been working on the Sand & Gravel General Permit reissuance for some time. The Historical Permit Information page provides information about past permit reissuance events, documents, and presentations for this process.
We will update the estimated current and future reissuance schedule below as necessary:
