Final 1200-Z Stormwater Discharge General Permit

On Aug. 1, 2017 DEQ renewed Oregon's 1200-Z general permit for the discharge of stormwater associated with industrial activities.

Permit Supporting Documents

The National Pollutant Discharge Elimination System (NPDES) 1200-Z general permit is required for industrial facilities that discharge stormwater from their industrial areas to surface waters of the state, or to storm drains that discharge to surface waters.
Examples of industrial activities that require a permit include manufacturing, transportation, mining, and steam electric power industries, as well as scrap yards, landfills, certain sewage treatment plants, and hazardous waste management facilities. See 40 CFR 122.26(b)(14) and (15) and permits below for list of industrial facilities that are required to obtain a permit.

NPDES Industrial Stormwater Discharge Permit

On Dec. 4, 2012, DEQ reissued Oregon’s general 1200-A permit for the discharge of stormwater from facilities with primary Standard Industrial Classification code 14, mining and quarrying of nonmetallic minerals, except fuels, including fixed and mobile asphalt and concrete batch plant operations. 

Effective Jan. 14, 2016, DEQ re-issued the 1200-A with modifications to make Tier II requirements and deadlines consistent with those in the 1200-Z and 1200-COLS permits. The modification description provides details of the changes.
