Amalgam Separators for the Dental Industry

The New York State Department of Environmental Conservation (NYSDEC) requires that all dental facility wastewater likely to come into contact with amalgam waste be treated prior to discharge by an amalgam separator (see 6 NYC RR 374-4). In addition, the U.S. Environmental Protection Agency (EPA) has recently adopted new regulations regarding the requirements for amalgam separators, the treatment of amalgam waste and best management practices (under 40 CFR Part 441).

To comply with these regulations, dental facilities located in New York City must notify the New York City Department of Environmental Protection when they install their amalgam separator using a “Compliance Report for Dental Office Amalgam Separator Installation” form. Dental practices that submitted an amalgam separator form prior to June 2018 are also required to submit the form below as it specifies new compliance requirements.

This form can be completed online or via hard copy. If you have trouble submitting or using the online form, please use and submit the hard copy version.
