Yesterday, the EPA proposed standards to reduce mercury discharges from dental offices. The proposal would require dental practices to comply with requirements for controlling the discharge of mercury and other metals in dental amalgam into publicly owned treatment works through the implementation and use of amalgam separators and best management practices. EPA is currently soliciting public comments on the proposed rule and the first public hearing on the matter will be held in November in Washington, D.C. Additional information from EPA can be found here. The EPA also has a fact sheet on the issue. You can also contact David Devaprasad for further information.
