EPA amalgam separator rule takes effect July 14

July 14, 2020, is the date for dental offices to be in compliance with a federal EPA rule that requires most practices to use amalgam separators and two best management practices recommended by the ADA. The rule pertains to dental offices that discharge water containing mercury and other metals present in amalgam into publicly-owned treatment works.

Besides needing to have the separator installed and in use, according to the EPA, if an office was discharging into a treatment plant before July 14, 2017, a one-time certifying compliance must be filed by Oct. 12, 2020, or within 90 days for a new office.
