The U.S. Environmental Protection Agency is proposing technology-based pretreatment standards for discharges from certain dental practices. The proposed rule was published in draft form on October 22, 2014. Public comments on the rule are due by February 20, 2015, and a final rule is estimated to be published in December 2016.
This rule would require a 2008 ISO 11143-certified amalgam separator with a removal efficiency of no less than 99.0% and select Best Management Practices for certain dental types. Regional San is participating in reviewing the regulations and providing comments.
