The Federal and State Pretreatment Program gives regulatory authority for EPA, states, and municipal governments to control the discharge of industrial wastewater into municipal Wastewater Treatment Plants (WWTPs) or Publicly Owned Treatment Works (POTWs). The objectives of the Pretreatment Program are to prevent pass-through, interference, or other adverse impacts to the POTW, its workers or the environment; to promote the beneficial reuse of biosolids; and to assure that all categorical pretreatment standards are met. There are approximately 620 Significant Industrial Users (SIUs) who discharge industrial wastewater to more than 130 POTWs throughout the State of North Carolina.
The Pretreatment, Emergency Response and Collection Systems (PERCS) pretreatment staff periodically present the following workshops as a service to assist POTWs and their consultants.
See the Training Page for details, including links to EPA training opportunities.
