New Amalgam Separator Requirement for Denver Metro Area

Molly Pereira Featured News

September 2, 2014

The Metro Wastewater Reclamation District (Metro District), which serves the Denver metro area, has implemented new amalgam control requirements for dental offices in its service area. By February 19, 2015, dental offices served by the Metro District will be required to implement Best Management Practices (BMPs) for placement, removal and disposal of dental amalgam. These dental offices will also be required to install amalgam separators by August 19, 2015.  The Metro District service area includes most of the Denver metro and surrounding suburban areas.

Under the new requirements, once BMPs and amalgam separators have been implemented in a dental office, the office will need to submit certification forms to let the Metro District know that the requirements have been met. Exemptions from these requirements are available for dental offices that never place or remove amalgam or teeth containing amalgam.

The CDA was made aware of the Metro District’s interest in an amalgam separator requirement in June 2013. Since that time, the CDA has been involved in providing feedback on draft rules to ensure that they are consistent with ADA policy on amalgam waste and as reasonable for dental offices as possible. The CDA was successful in achieving a year implementation timeline for dental offices that must install amalgam separators, and in helping to ensure that maintenance and recordkeeping requirements were the least burdensome necessary to accomplish the Metro District’s environmental needs.
