Effective July 14, 2017, the Environmental Protection Agency (EPA) enacted the Dental Amalgam Rule in an effort to reduce the amount of mercury introduced into the environment from dental amalgam discharged from dental facilities. Existing sources must comply with the standards in the rule by July 14, 2020.
Acting on behalf of EPA and the Arizona Department of Environmental Quality (ADEQ), the City’s Industrial Pretreatment Section requires a one-time compliance form be filled out by all practicing dentists within city limits. If you are a new dentist or have bought an existing practice, a form must be filled out and returned to the City within 90 days. If you are an exemption to the amalgam rule, the City requires a form to be filled out certifying the exemption.
