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. 

Reapplication Instructions and Information

All current permittees must have reapplied for the Sand & Gravel General Permit by April 4, 2015 (180 days before the expiration of the current permit). If you missed the deadline, you should still reapply. Permittees can now reapply or apply for a new Sand & Gravel General Permit in a secure, easy to use online system.

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