On July 24, 2017 the EPA’s final ruling became effective which requires the use of Amalgam Separators under the Clean Water Act to control discharge of mercury and other metals into public owned treatment works (POTWs) from dental practices.  This regulation was developed based on a separation and continual maintenance model that achieves a minimum 95% total reduction of total mercury from amalgam process wastewater.

Understanding New EPA Amalgam Compliance Rules 



Compliance with the pretreatment standard for new and existing offices are met by completing the following:

  • Install and properly maintain an amalgam separator that is ISO 11143:2008 certified or an ANSI/ADA standard No. 108 with a separation rate of 95%
  • Implement best management practices to properly collect and recycle “scrap” amalgam waste including chairside traps, vacuum pump filters, spent amalgam capsules and extracted teeth containing amalgam
  • Water line cleaners must have a pH of 6-8



All dental offices that place or remove amalgam are now required to implement an amalgam collection, separation and recycling program.  However, the EPA has identified exemptions to the new standards if less than 5% of activity involves amalgam.  Exempted practices include:

  • Mobile dental units
  • Dental offices where the practice “consists only” of the following specialties:
    • Oral Pathology
    • Oral and Maxillofacial Surgery
    • Orthodontics
    • Periodontics
    • Prosthodontics
