UPDATE: The EPA’s final rule (July 14, 2017) “requires dental offices to use amalgam separators and best management practices recommended by the American Dental Association (ADA).”
UPDATE: The 2016 EPA Dental Effluent Guidelines were pulled from The Office of The Federal Register; and, though signed, will not be published at this time. Therefore, this rule WILL NOT go into effect. However, many states have state level laws requiring the installation of amalgam separators in their state’s Dental Offices. These state level laws will be unaffected by the withdraw of the EPA rule and remain in full force and effect. If there are any further changes related to this rule, we will be sure to update this blog accordingly.
In September 2014, the Environmental Protection Agency (EPA) proposed a new rule regarding dental amalgam. This regulation would require all existing and new dental practices to use amalgam separators to prevent amalgam from discharging into publicly owned treatment works (POTWs).
