Pretreatment Program Approval Public Notice
Pretreatment refers to the reduction or elimination of pollutants in industrial process wastewater prior to discharging such pollutants into a publicly owned treatment works, or POTW. To address indirect discharges, the U. S. Environmental Protection Agency, through authorities in section 307 of the Clean Water Act, has established the National Pretreatment Program as part of the National Pollutant Discharge Elimination System, or NPDES, Permitting Program. The objectives are to prevent interference with the operation of the publicly owned treatment works, prevent pass-through of the pollutants and interference with the use or disposal of municipal sludge.
The National Pretreatment Program requires large publicly owned treatment works and smaller publicly owned treatment works with significant industrial discharges to establish local pretreatment programs (re: 40 CFR 403 and 10 CSR 20-6.100). The local programs must enforce all national pretreatment standards and requirements in addition to any more stringent local requirements necessary to protect site-specific conditions at the publicly owned treatment works.
The State of Missouri is required to provide public notice for the approval of the local pretreatment programs or any substantial modification of the programs in accordance with 40 CFR 403.11 and 10 CSR 20-6.100 (9). The public is encouraged to submit comments about the Pretreatment Programs in writing to the Missouri Department of Natural Resources. Please include the city’s name and the words “Pretreatment Program Approval” in all comment letters.
