NJDEP Dental Amalgam Program

Thanks to the continued cooperation of the New Jersey dental community, significant reductions in the discharge of mercury into the environment has been accomplished. (See below).

Dental Amalgam NJDEP Online Registration and Certification

Dental facilities are required to certify between 10/1 and 12/31 of each year, with the certification covering the period 10/1 to 9/30 of the reporting year.

Note: The NJDEP dental amalgam program is applicable ONLY to those dental facilities that generate amalgam waste through placement and/or removal of amalgam.


The Bureau of Nonpoint Pollution Control (BNPC) has issued a New Jersey Pollutant Discharge Elimination System Discharge to Ground Water (NJPDES-DGW) general permit for Dental Facilities Onsite Wastewater Treatment Systems. For more information, please contact the Bureau of Nonpoint Pollution Control or read more regarding the K2 General Permit.


Discharges into public sanitary sewers are regulated by the Bureau of Pretreatment and Residuals. All dental facilities subject to this regulation were required to implement Best Management Practices, or BMPs, by October 1, 2008, and must install an amalgam separator that meets the ISO 11143 criteria by October 1, 2009. Facilities that opened after October 1, 2007 shall immediately install an amalgam separator. Each dental facility subject to this regulation shall register and certify compliance annually with the NJDEP.

The renewal period is from October 1 through December 31 of each year.

Revised guidance manuals (updated September 15, 2011) are available. Prior manuals may no longer be applicable.

Results of the Rule

The effectiveness of the dental BMPs and the installation of the amalgam separators were assessed during calendar year 2012 by studying sewage sludge and wastewater effluent data. From the year 2008 (the year Dental Best Management Practices were required to be implemented) to the year 2011 (after required implementation of amalgam separators), there was a reported decrease of about 36 percent in wastewater mercury effluent concentrations, and a 31 percent decrease in sewage sludge mercury concentrations. The results are summarized below.
