Comparison: State vs. Federal
• Rules. Oklahoma is fully authorized to administer and enforce the National Pollutant Discharge Elimination System (NPDES) program (known as OPDES in Oklahoma) for regulating discharges, including for stormwater. The state follows the federal requirements for stormwater discharges with additional requirements for submittals and fees.
See the national section STORMWATER—GENERAL for information on the federal permitting program and the state sections STORMWATER—INDUSTRIAL FACILITIES, STORMWATER—CONSTRUCTION ACTIVITIES, and STORMWATER—MUNICIPALITIES for more information on the state requirements for these specific discharges.
• Administration and enforcement. The EPA-approved state OPDES program for stormwater discharges from most industrial facilities and construction activities is administered and enforced by DEQ's Water Quality Division. The EPA retains authority to administer the NPDES program on Native American lands in Oklahoma.
