Announcing the Draft Modification of the Sand and Gravel General Permit
Permit: The Washington state department of ecology (ecology) proposes to modify the sand and gravel national pollutant discharge elimination system (NPDES) and state waste discharge general permit (permit). The current permit was issued April 1, 2016, and appealed by the Washington Aggregate and Concrete Association. A settlement was reached on modified language for the permit in August 2017. The modified language allows more flexibility for portable operations and new concrete recyclers. The modified permit and fact sheet are available for review and public comment from September 26 through December 8, 2017, at 11:59 p.m.
Purpose of the Permit: The purpose of the sand and gravel general permit is to control the discharge of pollutants from sand and gravel mining operations and related facilities into waters of the state. This general permit provides coverage for discharges of process water, stormwater, and mine dewatering water associated with sand and gravel operations, rock quarries and similar mining activities, including stockpiles of mined materials, concrete batch operations, and hot mix asphalt operations. The permit authorizes wastewater discharges to waters of the state of Washington subject to the permit conditions.
