Sand and Gravel General Permit
Permit Purpose and Background
The Sand and Gravel General Permit controls the discharge of pollutants from sand and gravel mining operations and related facilities into waters of the state. Ecology modified the permit on August 17, 2011.
The permit regulates discharges of process water, stormwater, and mine dewatering water associated with sand and gravel operations, rock quarries, and similar mining operations, including stockpiles of mined materials. It 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.
