The ODEQ’s OKR05 permit is required for stormwater discharges associated with industrial activities under certain standard industrial classification (SIC) codes.  The SIC codes and sectors that are covered can be found in Table 1-2 of the OKR05 permit.

The OKR05 permit does not include the discharges from industrial activity which are related to oil and gas extraction, agricultural purposes, or located in Indian Country lands.  Obtaining OKR05 coverage fulfills your permit requirements on the state level; local municipalities are separate entities and may have different permit requirements.

OKR05 permitting procedures:

  1. First familiarize yourself with all the requirements in the OKR05 permit and develop a stormwater pollution prevention plan (SWP3) for your project.
  2. Complete a notice of intent (NOI) and return it to the ODEQ along with your permit fees.
    • The ODEQ’s Flex Viewer can be used to find the nearest water body.
    • If your facility prevents rain, snow, snowmelt, and/or runoff from being exposed to industrial materials and activities, you may apply for a no exposure certification.
  3. You will be notified by ODEQ if more information is required.  Once you receive your authorization you may begin discharging stormwater associated with industrial activities.  Your OKR05 permit does not cover any stormwater discharges that occur before your permit is issued.  While in operation, be sure you are following all the inspection, maintenance, training, and monitoring requirements as discussed in OKR05.
  4. In order to terminate coverage under OKR05, you may complete a notice of termination (NOT) and return it to the ODEQ.  The ODEQ will terminate your permit once the NOT is received. You may terminate coverage under your OKR05 by permit if one or more of the following conditions have been met:
    • A new owner/operator has assumed responsibility for the facility;
    • You have ceased operations at the facility and there no longer are discharges of storm water associated with industrial activity from the facility;
    • You have obtained coverage under an individual or alternative general permit for all discharges required to be covered by an OPDES permit.

The ODEQ provides a spill prevention and response procedures checklist and the EPA provides an industrial SWP3 development guide.
