1200-Z Industrial Stormwater Permit Correction 2023

Adopted rule

Administrative Order No.: DEQ-10-2023
Filed and Effective: July 20, 2023
See Oregon Bulletin, August 2023

Rulemaking contact: Krista Ratliff, 541-633-2033

In March 2021, the EQC adopted the 1200-Z permit by reference. DEQ inadvertently omitted a clause from the permit that has been in previous versions of the permit since 2007.

The Environmental Quality Commission approved adding this amendment to the permit: “Permit registrants are not required to conduct this evaluation for the benchmark parameter(s) for which DEQ or agent has granted a monitoring waiver in accordance with Schedule B.9 of this permit." Without this clause, permit registrants may incur high capital costs to install stormwater treatment based on one storm event sample results, which is not the corrective action framework the permit is based on.
