Construction activities which result in land disturbance of equal to or greater than one (1) acre, or less than one (1) acre if they are part of a larger common plan of development or sale that totals at least one (1) acre, are required to obtain the ODEQ’s OKR10 permit.

The OKR10 permit does not include the discharges from construction activity which are related to oil and gas extraction, agricultural purposes, or located in Indian Country lands.  Obtaining OKR10 coverage fulfills your permit requirements on the state level; local municipalities are separate entities and may have different permit requirements.

OKR10 permitting procedures:

  1. First familiarize yourself with all the requirements in the OKR10 permit and develop a stormwater pollution prevention plan (SWP3) for your project.
  2. Complete a notice of intent (NOI) (writable form) and return it to the ODEQ along with your permit fees.
  3. You will be notified by ODEQ if more information is required.  Once you receive your authorization you may begin your project.  Your OKR10 permit does not cover any stormwater discharges that occur before your permit is issued.  While your project progresses, be sure you are following all the inspection, maintenance, training, and stabilization requirements as discussed in OKR10.
  4. Once you have finished your project and are confident that you have met all the necessary requirements, 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.
    • If you are not sure if you have met the stabilization requirements, you may request an inspection from your local ODEQ representative. The inspection request form can be found here.
