The Industrial Pretreatment Program prevents the discharge of pollutants to Publicly-Owned Treatment Works (POTWs) which will interfere with the operations of the POTW or its use and disposal of municipal biosolids. In addition, the Pretreatment Program prevents the introduction of pollutants to POTWs that may pass through into rivers, lakes, and streams causing toxicity or other impacts. Implementation of the Pretreatment Program is defined at 40 CFR Part 403. These regulations describe the responsibility of the EPA, states, POTWs, and industrial users in protecting the POTWs, sewer systems, biosolids, receiving waters, and worker health and safety. You may visit the EPA National Pretreatment Program website for more information on waste water treatment involving Biosolids/Sludge.
