Follow two Best Management Practices

  • Do not discharge scrap amalgam waste to city sewer.
  • Do not use line cleaners such as bleach, chlorine, iodine or peroxide that have a pH level higher than 8 or lower than 6.


Offices in operation before 7/14/17:

  • Install separator by: 7/14/20
  • Submit compliance report by: 10/12/20

Offices beginning operation after 7/14/17:

  • Install separator at opening of office
  • Submit compliance report: within 90 days of installation


Dental facilities that do not place or do not remove dental amalgam, except in limited emergency or unplanned circumstances are exempt from any further requirements but must submit the one-time compliance report.

Dental facilities that exclusively practice one or more of the following specialties are not subject to any of the rule’s requirements:

  • Oral pathology
  • Oral and maxillofacial radiology
  • Oral and maxillofacial surgery
  • Orthodontics
  • Periodontics
  • Prosthodontics

Mobile units and those offices which do not discharge their amalgam wastewater to a municipal wastewater treatment plant are also not subject to the requirements of this regulation.
