Amalgam Separators Required in NH

Organization(s) New Hampshire Dept. of Environmental Services
Project Description This past June, the NH DES adopted a regulation requiring all dental facilities to install an approved amalgam separator by October 1, 2005. Under this new rule, dental practitioners have to install an amalgam separator meeting ISO 11143 standards and manage the trapped amalgam as a hazardous waste, although amalgam can be managed in a similar fashion to a Universal Waste due to an exemption for recycled amalgam in the Hazardous Waste Rules

In mid-June, the NHPPP sent a mass mailing to all 1,260 NH licensed dentists reminding them of their obligation under the new requirements. The mailing included a certification statement indicating an approved amalgam separator has been installed as well as a form the dentist may sign indicating he/she is exempt or qualifies for a de-minimis waste generation waiver. To date, about 10 percent of the dentists have returned signed certification forms or exemption statements.
