Protection Agency Dental Amalgam Rule
On June 9, 2017, the Environmental Protection
Agency enacted the Dental Amalgam Rule in an effort to reduce the amount of
mercury introduced to the environment by dental amalgam. The rule is effective
on July 14, 2017. The date that existing dental facilities subject to the rule
must comply with the standards in the rule is July 14, 2020.
The final rule applies to dental facilities
that discharge to the City of Phoenix sewer system from where the practice of
dentistry is performed, including large institutions such as dental schools and
clinics; permanent or temporary offices, home offices, and facilities; and
including dental offices owned and operated by federal, state, or local
governments including military bases.
The rule requires dental offices to install
and operate an amalgam separators(s), to implement two Best Management
Practices (BMPs), and to submit a One-time Compliance Report to the Control
Authority. City of Phoenix Environmental Services Division is the Control
Authority for all dental facilities that discharge to the City of Phoenix
sanitary sewer. Thereafter, the dental office will be required to conduct
ongoing operation and maintenance and maintain associated records. These
activities can be facilitated by third parties such as dental office suppliers
and amalgam separator manufacturers.
