The Dental Amalgam Rule (40 CFR 441) is a new categorical standard in the USEPA’s Pretreatment Program requiring dental offices to report use and pretreatment of dental amalgam. The USEPA finalized technology-based pretreatment standards under the Clean Water Act (CWA) to reduce discharges of mercury and other metals from dental offices into publically owned treatment works (POTWs). The new CWA regulation became active in 2017. The MWRD, as the local POTW and control authority, is required to enforce these regulations. If you are a dental office, you are required to file a Dental Amalgam Compliance Report. This form, and other documents that help explain the regulation and its requirements, can be found below. If you have any questions, please contact MWRD at (312) 751-3044 or at DentalAmalgam@mwrd.org.
