ADA Statement on Proposed EPA Amalgam Rule
September 30, 2014
Washington, D.C. – The ADA is reviewing a draft rule intended to reduce the amount of dental amalgam that dental offices release into wastewater systems published today by the Environmental Protection Agency (EPA). The Association will comment on the rule once that review is completed.
The Association has consulted with the EPA over the past several years as the agency developed the rule and supports a reasonable national pretreatment standard for amalgam waste so long as it is not unduly burdensome on dental professionals. There are technical differences between the ADA’s position and what EPA is proposing, and some of these differences may be significant. The Association will point out these issues in its comments on the rule.
The proposed rule is based largely on the Association’s best management practices, including the use of amalgam separators, collection devices installed in dental office plumbing to capture and remove solid waste particles before they enter the sewer system. The use of separators allows greater recycling and reduces the amount of amalgam entering wastewater treatment plants. Very little—less than 1 percent—of the mercury released into the environment comes from dentistry. Dental amalgam, a safe, affordable and durable material with an established record of safety and effectiveness, is a mixture of metals, including silver, copper, tin and mercury.
