Storm water discharges are generated by runoff from land and impervious areas such as paved streets, parking lots, and building rooftops during rainfall and snow events. Storm water often contains pollutants in quantities that could adversely affect water quality. Most storm water discharges are considered point sources and require coverage by a National Pollutant Discharge Elimination System (NPDES) permit. The primary method to control storm water discharges is through the use of best management practices (BMPs).

Ohio EPA’s Industrial Storm Water General Permit (OHR000005) will expire on December 31, 2016. Ohio EPA expects to public notice the draft general permit renewal for public comment in Summer 2016. Once the general permit renewal is issued final, Ohio EPA will notify all existing permittees with instructions for renewing coverage under the next generation Industrial Storm Water General Permit (OHR000006). Please do not attempt to renew your Industrial Storm Water General Permit coverage until you receive a renewal notice from Ohio EPA.
