1200-Z Permit Update

October 2018

DEQ has committed to issue a revised permit upon reconsideration by October 31, 2018. We are currently working on the changes to the permit, revised permit evaluation report and associated documentation to implement the revised 1200-Z permit. Mailings will include, new permit assignment letters specifying increased monitoring frequency and applicable changes to sampling parameters requirements.
Permit registrant’s coverage will be uninterrupted and no action is required of industries assigned to the 1200-Z general permit. DEQ’s updates will continue through our website, newsletters and direct mailings.


Current 1200-Z Stormwater Discharge General Permit

The permit was renewed on Aug. 1, 2017. This 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 of the state.


Status of the 1200-A Stormwater Discharge General Permit

On Dec. 3, 2017, Oregon's 1200-A general permit for the discharge of stormwater associated with sand and gravel mining activates expired. DEQ is actively researching best practices for managing the discharge of stormwater from facilities covered under the 1200-A permit, and does not have a timeline for issuing the renewed permit.
