Dentists must comply with the Environmental Protection Agency's (EPA) Dental Amalgam Rule. The rule aims to reduce discharges of mercury from dental offices into publicly owned treatment works (POTWs).

Best Management Practices

• Install an ISO 11143-compliant amalgam separator or equivalent device
• Use neutral pH, non-oxidizing, non-chlorine based line cleaners
• All amalgam process wastewater, including chair side traps, screens, vacuum pump filters, dental tools, cuspidors or collection devices are treated through the amalgam separator
• Provide one time compliance form to Centennial Water

One-time Compliance Form

This form contains the minimum information dental facilities must submit in a one-time compliance report as required by the Effluent Limitations Guidelines and Standards for the Dental Office Category (“Dental Amalgam Rule”).
