1200-Z Industrial Stormwater Discharge Permit Renewal

Adopted rule

Administrative Order No. DEQ-6-2021 
Filed and effective: March 25,  2021
See Oregon Bulletin, April 2021

The Environmental Quality Commission adopted rules to renew Oregon’s industrial stormwater permit, officially called the National Pollutant Discharge Elimination System Stormwater Discharge General Permit No. 1200-Z. This permit regulates stormwater discharges from industrial facilities that may reach Oregon waterways, directly or through conveyance system such as ditches or storm drains. The permit currently covers over 830 industrial facilities in Oregon.

Advisory committee

DEQ worked with an advisory committee of technical experts to investigate the feasibility of putting new limits on certain contaminants. DEQ also evaluated if it’s feasible to set discharge limits based on impaired waterbodies. 

 

​​​​​This committee's purpose is to provide expert input on policy and technical issues concerning this rulemaking.
