The EPA Administrator, Gina McCarthy, signed the final rule on December 15, 2016, and the rule was published in the Federal Register (FR) on June 14, 2017.  The rule takes effect on July 14, 2017. See the final rule HERE

  • Learn how the EPA regulations affect your practice
  • Understand what you must do in order for your office to be in compliance with the law
  • The onus is on you and your staff to make sure your practice properly recycles dental amalgam waste and handle the necessary reporting

The new regulations purpose is to ensure that dentists properly collect and recycle ALL amalgam waste they generate during the placement or removal of amalgam restorations in order to contain mercury at its source. The new regulations emphasize compliance, documentation AND enforcement. Previous mandatory programs (in some states) emphasized only equipment purchases and did not provide for inspection of offices or mandate other types of enforcement. These new regulations are more exhaustive because their emphasis is on demanding both compliance with proper recycling and documentation as well as establishing mechanisms to inspect those offices suspected of non-compliance.

What the regulations mean for your office:

  1. The regulations apply to anyone who either places or removes dental amalgam.
  2. Included are permanent and temporary dental offices, hospitals, schools, clinics, mobile units and facilities owned by federal, state or local governments.
  3. The regulation requires the installation, maintenance, monitoring, and recycling of an amalgam separator in addition to requiring compliance with ADA Best Management Practices (BMP’s) regarding the recycling of “scrap amalgam” (excess mix or carvings, empty capsules from pre-capsulated alloy, extracted teeth containing amalgam, in -line disposable traps and Evac-u-Traps from wet-vac systems).

Amalgam Separators must:

  1. Be compliant to ISO 11143:2008 standard to operate at a minimum of 95% efficiency.
  2. Be inspected at least monthly for proper operation.
  3. Be properly sized to incorporate all the wastewater that may pass through it.
  4. Have canisters, cartridges or units changed when full, as recommended by the manufacturer, for recycling.
  5. Be properly maintained so unprocessed wastewater cannot bypass the system and enter a drain.

Scrap amalgam handling, collection and recycling:

  1. Must include all items considered to be “scrap amalgam” (previously listed).
  2. Requires the use of non-chlorinated line cleaners in the pH range of 6 to 8.
  3. This waste must never be placed in with regular trash or bio-hazardous (red bag) waste.

Monitoring, reporting and record keeping:

Monitoring and enforcement will be conducted by your local wastewater treatment facilities (POTW’s).

To maintain compliance, the office must certify that:

It has installed and is properly maintaining, inspecting, and recycling an amalgam separator compliant to ISO 11143:2008 standard previously noted.

EPA suggests dental offices consider use of signs displayed prominently in the office or electronic alendar alerts to remind staff of dates to perform and document monthly inspections, cartridge replacement, etc.

  • Canisters, cartridges, or separator units are being recycled to manufacturer's specifications.

It adheres to all BMP's and recycles all scrap amalgam.

Offices are required to submit a one-time compliance report.


According to the EPA website, the rule takes effect 30 days after it appears on the Federal Register, which occurred on June 14, 2017. The compliance date is 36 months from the effective date of the rule.  

Being an early adopter can afford the office a number of benefits:

  • Lower cost of equipment and other waste management cost savings for the office
  • Recognition that you are contributing to the local community
  • Training staff immediately on this issue to insure future compliance
  • Free CE Course: “Public Health, the Environment and Dentistry: From Policy to Clinical Practice”– (Retail value $ 399)
    • This 8 CE credit course is the leading educational tool for compliance with environmental regulations effecting the dental profession. It is free for any Kerr customer.

The single most important aspect is to insure your office recycles on a timely basis.  Non-compliance is problematic.  

Simply purchasing a piece of equipment, such as an amalgam separator, from your dental supplier does NOT achieve compliance.

An Effortless Way for Dental Practices to Protect the Environment

My dental practice’s experience

By: Gary Radz, DDS

As a long-term practicing dentist, I have been continually mindful of the potential impacts dentistry can have on the environment. It is for this reason that I have been steadfast in my commitment to properly handling and disposing of all amalgam waste generated at my practice. I have been utilizing an amalgam separator since 2011 and have consequently prevented 2.3 lbs. of mercury from entering the local wastewater system. When it comes to a substance as harmful and toxic as mercury, every bit counts. A single pound of mercury is enough to contaminate a 22 acre lake to the point where fish consumption should be carefully monitored. With the proximity of Cherry Creek and the South Platte River to the Denver area, it is vital to the health of these aquatic systems that mercury is prevented from reaching their depths.

The harm posed by this substance has prompted the U.S. Environmental Protection Agency to propose effluent guidelines for dental discharges of amalgam, which it did on September 25, 2014. Prior to this, the Denver Metro Area imposed guidelines for best management practices for amalgam waste. The efforts I have put in over the years already prepared me for the Denver guidelines and even though the EPA regulations are much more stringent than in Denver, I am already equipped to be in compliance with the rule when it is finalized. Over the years, my waste management needs have been addressed through Dental Recycling North America, Inc. Although several companies sell amalgam separators, none tackle the issue as successfully as DRNA does. DRNA’s understanding of the regulatory landscape, its annual recycling services, and provision of compliance documentation ensures that all regulatory matters are adequately addressed.  I have had the DRNA system in my office for 5 years now. It's simple, turnkey and affordable. They do all the heavy lifting and will get you into compliance with minimal effort on your end. I feel this one is a no brainer.

Evac-u-Trap Recycling

Tips for properly recycling amalgam waste at your office

The Evac-u-Trap is a disposable canister, lid, mesh filter and gasket designed to replace the present canister and filter in your central vacuum pump. To remove this canister, screw on the lid and segregate with your contact amalgam for recycling. The infectious material is sealed in the canister where it cannot spill or contaminate the workplace. Nothing needs to be cleaned and you can be assured that you have minimized all contact with infectious material.

Amalgam Recycling Regulations


Why DRNA is your best choice to be in compliance at the most economical cost:

  • This is a waste management issue, not simply purchasing equipment
  • The rule requires annual recycling and providing environmental officials various documentation
  • DRNA does all this for the office on an ongoing basis
  • It’s equipment cost are significantly less than its main competitor, which is sold by dental dealers
  • It locks in its recycling cost over several years so NO ESCALATING COST like others on the market who seek to raise their recycling cost annually
  • DRNA is the dental office’s NO COST environmental compliance partner and will interface with local environmental officials on your behalf if needed.

These are a few examples of major dental institutions which have sought a complete compliance solution versus simply purchasing a piece of equipment.

Compliance Report

As part of the EPA regulation, offices will need to submit various written documentation to the regulatory authorities. This can be an ever changing process in terms of what documentation is required. For example, the current rule states monthly inspections in order to be in compliance.

DRNA provides monthly updates as well as assisting in all required documentation whether it be monthly, quarterly, or annually to the appropriate regulatory authorities.  For all Kerr customers whom become customers of DRNA, the annual service fee of $399.00 is waived
