The Oklahoma Department of Environmental Quality (DEQ) has authority over industrial stormwater permitting. The DEQ has adopted a Multi-Sector General Permit for Industrial Activities (OKR05) that should be consulted about your permit coverage. DEQ’s OKR05 permit website includes document templates, forms and instructions for applying for coverage.

Specific types of industrial activities were selected for permit coverage because they have the greatest potential to contribute pollutants in stormwater runoff. Some of these activities apply to cities, for example operation of a sewage treatment plant. If you are not on the 1991 list of industrial activities, you still have responsibility under Federal, State and local authority to not cause releases of pollutants. These include but are not limited to restaurants, automotive services, landscapers, carpet cleaners, and power washing businesses.

Actions that a business can take are called Best Management Practices (BMPs). These can prevent or reduce pollutants in stormwater runoff. In addition, many BMPs make good business sense by improving the efficiency of inventory processing and increasing workplace safety.
