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. 

Permit Reissuance

The current Sand & Gravel General Permit will expire October 1, 2015. Ecology plans to revise and reissue the new permit in November 2015 with an effective date of January 1, 2016.
