The amalgam recycling rule is an implementation of the Clean Water Act and was in effect as of July 14, 2017. It is designed to reduce the discharge of amalgam waste from dental offices into the municipal sewage. If you practice in a state or municipality that already has an amalgam separator rule that’s not quite the same as this federal rule, they may have reporting requirements that differ so you may need to continue those reporting obligations. However, the state or municipality (which handle the administration of this federal rule) may decide to conform their requirements to this federal rule and EPA has encouraged this approach, but not mandated it. The entire rule may be read here.
The rule mandates that most dental offices install, maintain, and monitor an amalgam separator that complies with the American National Standards Institute (ANSI) American National Standard/American Dental Association (ADA) Specification 108 for Amalgam Separators (2009) with Technical Addendum (2011) or the International Organization for Standardization (ISO) 11143 Standard (2008). You may continue to operate an already installed amalgam separator for its lifetime or ten years (whichever comes first), as long as you comply with the other rule requirements including the specified Best Management Practices (BMP), operation and maintenance, reporting, and record-keeping requirements. Newly purchased or built offices must comply within 90 days of taking ownership.
Dental offices must also submit a compliance report. Additionally they will need to have maintenance and inspection records available.
