Dental Amalgam Management

Dental Amalgam Management

The City Manager has amended the 2007 rules Concerning Treatment and Disposal of Dental Amalgam Wastewater Within the City of Boulder. See justification for the amended rules pdf for more information.

These rules protect the city’s wastewater treatment system and Boulder Creek from excessive amounts of mercury in order to:

  • Protect human health, aquatic life, and wildlife;
  • Comply with the state’s limit for clean waterways;
  • Meet the city permit requirements for the quantity of mercury discharged to Boulder Creek;
  • Meet the requirements of the new EPA Dental Point Source regulation put into effect July 14, 2017.

This rule established requirements for controlling the discharge and recycling of amalgam wastewater from dental practices. The purpose is to reduce mercury in wastewater by preventing its release from the source through proper handling and the use of filters and separators in dental practices.

The final rule pdf is available for review online or by requesting a copy from Central Records in the Municipal Building, 1777 Broadway, 2nd Floor.
