Pretreatment Profile

The pretreatment program is mandated under the federal Clean Water Act ad U.S. EPA has delegated the program to Ohio for implementation.  In accordance with the City of North Olmsted’s NPDES Permit, The City of North Olmsted administers an Ohio EPA approved Pretreatment program under the guidance of Ohio EPA and US EPA and the authority of the Clean Water Act, the NPDES program, 40 CFR 112, and the general pretreatment regulations of 40 CFR 403. As well as Ohio OAC 3745-3 and The City of North Olmsted Ordinance 917.01 to 917.99. This program monitors 188 total industrial users, which consists of 2 categorical SIU and 186 non-significant, non-categorical industries (i.e. commercial businesses). Since June 1, 2010, this program has been operating under the North Olmsted WWTP NPDES permit numbers 3PD00016*LD, 3PD00016*MD, & 3PD00016*ND authorized by Ohio Environmental Protection Agency.  The pretreatment department is responsible for implementing the pretreatment program. 

The pretreatment program regulates industrial facilities discharging wastewater to publicly owned treatment works (POTWs).  These facilities, known as industrial users, discharge process wastewater often contaminated by a variety of toxic or otherwise harmful substances.  Because POTWs are usually not specifically designed to treat these substances, pretreatment programs are needed to eliminate potentially serious problems that occur when these substances are discharged into public sewer systems. 

The City of North Olmsted service area contains two categorical but Non-Significant IUs. Aside from our two categorical industries, our efforts are concentrated on small industrial users (commercial businesses including dentists, gas stations, auto body shops, dry cleaners, and restaurants, which include hotels, bars, and nursing homes). With this in mind, we use the Enforcement Response Plan (ERP) along with the City of North Olmsted ordinances to control the discharge of contaminants into the sanitary sewer system. The main objective of the program is to prevent any hazardous, toxic, explosive, and/or other unwanted materials from entering the City’s sewer system.
