The Environmental Protection Agency (EPA) has officially signed and submitted the final rule on dental amalgam effluent limitations for publication in the Federal Register (FR). With the rule going into effect on July 2020, HealthFirst is helping inform dental practices of the top 5 things they need to know about the new EPA dental amalgam rule.
Practices Affected by the EPA Dental Amalgam Rule
This rule applies to all offices that practice dentistry and discharge their wastewater to a Publicly Owned Treatment Works (POTW), including large institutions and dental clinics. It does not apply to mobile units or certain dental specialties, such as: oral pathology, oral and maxillofacial radiology, oral and maxillofacial surgery, orthodontics, periodontics, or prosthodontics.
EPA Requirements for Affected Offices
If you are a dental office that places or removes amalgam and discharges to a POTW, you must do the following:
- Operate and maintain one or more ISO 11143 compliant amalgam separators.
- Follow two Best Management Practices (BMP)
- Must not discharge scrap amalgam waste to POTWs.
- Must not use line cleaners that have a pH level higher than 8 or lower than 6.
ISO 11143 Compliant Amalgam Separators
The EPA rule states that all amalgam separators installed by dental practices must achieve ISO 11143 standards for mercury removal efficiency and design requirements. The International Organization for Standardization (ISO) established standard 11143 for measuring amalgam separator efficiency and included certain design requirements for proper use and maintenance.
The EPA rule requires that all amalgam separators being installed today must achieve at least a 95% removal efficiency. The EPA also recognizes that offices may currently have amalgam separators in place that do not meet the new requirements. These offices are allowed to continue to operate these older separators for their lifetime or ten years (whichever comes first) as long as the dental practices comply with the other rule requirements, such as following the specified BMPs, operation, and maintenance, reporting, and record-keeping requirements.
Visual or Auditory Warning Indicator
Because warning indicators make it easy to detect when the separator is not operating optimally, the ISO 11143 standard requires that all non-sedimentation separators must have an auditory or visual sign warning indicator when the separator is nearly full or in by-pass mode.
While not required for sedimentation amalgam separators, some manufacturers of these separators have included visual or auditory warning indicators into their design.
Compliance Reports and Maintenance Records
All dental offices, whether they place or remove amalgam, must submit a One-Time Compliance Report to Control Authorities.
For dental offices that place or remove dental amalgam, the One-Time Compliance Report must include information on the dental facility and its operations and a certification that the dental discharger meets the requirements of the applicable performance standard.
For dental offices that do not place or remove dental amalgam (except in limited circumstances), the One-Time Compliance Report must include information on the facility and a certification statement that the dental discharger does not place dental amalgam and does not remove amalgam except in limited circumstances.
Amalgam Separator Operation and Maintenance Records
For those offices required to install an amalgam separator must also maintain records of ongoing operation and maintenance. These maintenance records can be facilitated by third parties, such as dental office suppliers and amalgam separator manufacturers.
