Ohio EPA Phase II Stormwater General Permit
Mandated by Congress under the Clean Water Act, the United States Environmental Protection Agency (EPA) implemented the NPDES Stormwater Program – a comprehensive two-phased national program for addressing the non-agricultural sources of stormwater discharges which degrade the quality of our nation’s waters. The program uses the National Pollutant Discharge Elimination System (NPDES) permitting mechanism to require the implementation of controls designed to prevent harmful pollutants from being washed by stormwater runoff into local water bodies. In Ohio, the NPDES Permit Program is administered by Ohio EPA.

In January 2009, Ohio issued Clermont County and 13 local townships and municipalities its second Phase II Stormwater General Permit from Ohio EPA. This permit authorizes the discharge of storm water to the county’s rivers, lakes and streams, provided that six minimum controls are met. These controls include public education, public involvement, illicit discharge detection and elimination, construction and post-construction runoff control, and pollution prevention. The six minimum controls must be addressed in a Storm Water Management Plan developed an implemented by the permittee.
