Cumberland WWTP Pretreatment Program

All industrial and/or nondomestic sewer users shall comply with the federal general pretreatment regulations in 40 CFR Part 403 and the applicable national categorical pretreatment standards set out in 40 CFR Chapter I, Subchapter N, Parts 401 through 471 upon promulgation and all applicable federal, state, or local requirements or standards. 

General and specific prohibitions are national standards. These standards apply to all nondomestic dischargers that discharge wastewater to a publicly owned treatment works (POTW). They apply whether or not the POTW has an approved pretreatment program and also whether or not the nondomestic discharger has been issued a control mechanism or permit. EPA developed these standards with the intent to provide protection for POTWs, which include a treatment plant’s collection system.
