IDEM Seeks Input on Phosphorous Limit for Major Sanitary Wastewater Treatment Plants


By Andy Bowman, Attorney, Bingham Greenebaum Doll LLP

The Indiana Department of Environmental Management (IDEM) is seeking comment on a proposed Non-Rule Policy Document (Water -019-NPD) that will require major Indiana Publicly Owned Treatment Works (POTWs) and semi-public sanitary wastewater treatment plants with design flows of 1 million gallons per day or more to limit phosphorous discharges to 1.0 milligrams per liter (mg/l). The new limit will be included in National Pollutant Discharge Elimination System (NPDES) permits for which an application is submitted after Jan. 1, 2015. For applications due and received prior to Jan. 1, 2015, the permit will include a “report only” requirement and the new phosphorous limit will not be included until the next permit renewal.

Comments may be submitted until Oct. 24, 2014, to: Jason House, IDEM, 100 North Senate Avenue, MC 65-42, IGCN 1255, Indianapolis, IN 46204-2251 or
