Ohio EPA has issued a final general National Pollutant Discharge Elimination System (NPDES) permit for temporary wastewater discharges in Ohio.

Temporary discharges may be associated with some type of facility or site cleanup, or one-time emergency discharge due to unusual or short-term circumstances, or discharges from a pilot project or test facility. The type of pollutants found in temporary discharges may be quite variable due to the differences in projects. Also, flow rates could be quite different depending on the size of the project. The concentration of the discharges must be de minimus, defined as less than ten percent of the waste load allocation for all applicable pollutants. In addition, temporary discharges are defined as facilities or projects that discharge for a time period not to exceed 60 days.
