2040-AF26 201704 Unified Agenda of Federal Regulatory and Deregulatory Actions 2040 Office of Water OW 2000 Environmental Protection Agency EPA Effluent Guidelines and Standards for the Dental Point Source Category

The EPA finalized technology-based pretreatment standards under the Clean Water Act (CWA) for discharges of pollutants into publicly owned treatment works (POTWs) from existing and new dental practices that discharge dental amalgam into POTWs. Dental amalgam contains mercury and other metals that have the potential to pass through or interfere with wastewater treatment at POTWs. EPA’s pretreatment rule establishes a uniform national standard to control mercury discharges based on amalgam separators and two best management practices.
