The Oklahoma Pollution Discharge Elimination System (OPDES) stormwater program, authorized by the NPDES stormwater permitting program, requires construction site owners/operators to obtain coverage under the OPDES Construction General Permit OKR10 to discharge stormwater from their construction sites and implement appropriate pollution prevention controls/techniques to minimize pollutants and reduce stormwater runoff.

A permit is required before construction activity can start at a site. Discharge of stormwater from a construction site without first obtaining a permit from DEQ is in violation of Title 27A O.S. §2-6-205 of the Oklahoma Statutes. As part of the application, the owner and/or operator must develop and implement a Stormwater Pollution Prevention Plan (SW3P) to minimize pollutants and reduce stormwater runoff.  A construction permit cannot be issued, and construction cannot begin, until these requirements are met.
