DENTAL MERCURY – WASTEWATER PERMIT COMPLIANCE
In June of 2017, the United States Environmental Protection Agency, (USEPA), passed a Dental Office Category Rule, (codified at 40 CFR § 441) governing regulations related to dental offices nationwide. This EPA ruling went into effect July 2020. The ruling specifically stated that by July 14, 2020, the following must be implemented in dental offices:
1. Operate and maintain one or more ISO 11143 compliant amalgam separators
2. Implement Best Management Practices
3. Comply with reporting and recordkeeping requirements
4. Complete an EPA approved One-Time Certification Form
Please note: If your practice complies with San Francisco’s Dental Program requirements you are in compliance with 40 CFR § 441. All dental practices in San Francisco were required to complete the One-Time Certification Form by September 1, 2020, submitting it to:
Dental Mercury Reduction Program
San Francisco Public Utilities Commission
Collection System Division

San Francisco Dental Mercury Reduction Program Permit Changes
Starting this year, the San Francisco Public Utilities Commission (SFPUC) is changing the permit system for the Dental Amalgam Reduction Program. Instead of each dental office applying for individual Wastewater Discharge Permits, the SFPUC has granted a General Wastewater Discharge Permit to all dental practices in San Francisco.
Dental offices are still required to follow Mandatory Best Management Practices as established by the SFPUC, and all dental practices are required to install a city approved amalgam separator if they place or remove amalgam fillings. An exemption is granted by the SFPUC to dental practices that place or remove amalgam fillings three (3) days or less in one calendar year.
More information on the San Francisco Dental Amalgam Reduction Program can be found on the Public Utilities Commission’s website, under the subheading 'Pretreatment Program', in the 'Sewer' section of their 'About Us' page.
