Ohio was authorized by U.S. EPA to implement the National Pollutant Discharge Elimination System (NPDES) under the Clean Water Act (CWA) (Section 402(b) and 40 C.F.R. Part 123) on March 11, 1974. Authorized states assume permitting authority and are required to administer the program in a manner no less stringent than the CWA and regulations adopted or subsequently amended by EPA. By law Ohio EPA must review these rules every five years. Pursuant to the five year rule review, the agency is soliciting initial input on draft rule revisions for nine of the ten rules in the chapter. The agency is considering minor revisions and updates to style and references to all of the rules in this chapter. Please see the fact sheet for specific details. The agency is also requesting feedback on two draft additive forms (here and here). The OMA’s contact is Rob Brundrett. 2/22/2018
