Dental Mercury Reduction

Dental practices that place or remove amalgam fillings (which can contain from 40% to 50% mercury) are a controllable source of mercury that impacts the City’s sewer systems. Consequently, all dental offices that are connected to the City and County of San Francisco’s sanitary sewer system are required to reduce their discharge of dental amalgam wastes to the lowest practicable level.

Permits
Dental practices must submit the following forms and permits to the City and County of San Francisco:

• Dental Practice Wastewater Discharge Permit Application Form
• Mandatory Best Management Practices (BMPs)
• Instructions for Completion of Permit Application
• Example of Completed Permit Application
• Mandatory Best Management Practices Certification Form

Upon receipt of your permit, you must sign and submit the Mandatory BMPs Certification Form to certify that you have implemented the required Best Management Practices.
