Overview: EPA “Dental Rule” Regulation on Amalgam Waste
Per the EPA, effective July 14, 2020, all existing dental practices were required to install either an ISO 11143:2008 certified amalgam separator or a certified ANSI/ADA Standard No.108 amalgam separator, both at a separation rate of 95%.
Now, for existing offices, a One-Time Compliance Report must be submitted to the local Control Authority (POTW) no later than October 12, 2020.
- Offices must maintain and make available for inspection in either physical or electronic form, all associated documentation for a minimum of three years.
The ADA petitioned the EPA to push the effective date due to Covid-19, the EPA instead suggested that local authorities refrain from enforcement until October 12, 2020, the date on which all compliance certification is due to the local water control authority.
- Solmetex has heard several stories from practices who have received warnings or citations, with the potential for monetary fines and office closures, from POTW inspectors regarding their lack of compliance.

Overview: “Effluent Limitations Guidelines and Standards for Dental Offices”
Solmetex has the experience and products to ensure your practice is in full compliance with the EPA regulation “Effluent Limitations Guidelines and Standards for Dental Offices“, commonly referred to as the “Dental Amalgam Rule”. Below are the key points from the new EPA regulation.
EPA Dental Regulation Implementation Period:
ALL dental practices are required to install either a ISO 11143:2008 certified amalgam separator or a certified ANSI/ADA Standard No.108 amalgam separator, both at a separation rate of 95%.
- New dental practices have 90 days to install an amalgam separator.
- Existing dental practices have until July 14, 2020 to install an amalgam separator.
- Existing dental practices who already have an amalgam separator installed have until July 14, 2024 to install an amalgam separator that meets all the regulation requirements.
The dental rule applies to offices, including large institutions such as dental schools and clinics, where dentistry is practiced that discharge to a POTW. The new EPA dental regulation does not apply to mobile units or offices where the practice of dentistry consists only of the following dental specialties: oral pathology, oral and maxillofacial radiology, oral and maxillofacial surgery, orthodontics, periodontics or prosthodontics.
- The regulation requires dental offices to follow manufacturer’s guidelines when changing out their containers.
- Dental offices that discharge to POTWs but do not place or remove amalgam need only submit a certification.
- Dental offices that place or remove amalgam must install, operate and maintain an amalgam separator and must dispose scrap amalgam properly (may use a Solmetex amalgam bucket).
- Dental offices must use line cleaners with a pH level between 6-8.
- Dental offices must submit a compliance report. While these reporting mechanisms will be required the details on how and when they are to be done is still to be determined and will mostly likely fall to the individual states and local water authorities.
- Each dental office will be responsible for implementing the ADA’s Best Management Practices (BMPs) regarding amalgam waste within their practice. While amalgam separators are the focus of the proposed regulation, the regulation is about responsible management of amalgam waste.
- Dental offices are required to manage the disposal of wet amalgam waste (amalgam separator) and dry amalgam waste (amalgam bucket for example) as defined in the BMPs. Dry amalgam waste includes all items that come in contact with amalgam, such as chairside traps, amalgam capsules, vacuum filters and contact & non-contact amalgam.
- A malfunctioning amalgam separator must be repaired or replaced no later than 10 days after the problem is discovered.
