Under Vermont law, dental offices are required to follow environmental “best management practices”

    developed by the Vermont Department of Environmental Conservation for amalgam, elemental mercury, and other common hazardous wastes. In addition, all dental practices except for orthodontists, periodontists, endodontists, oral and maxillofacial surgeons, and any other dental practice that does not place or remove amalgam, are required to install amalgam separators no later than January 1, 2007.

    This certification form, which provides the best management practices in a checklist format, must be completed by Vermont dental practices and filed with the Department of Environmental Conservation by January 31, 2007, and every other year thereafter (i.e., January 31, 2009, 2011, 2013, etc).

Resource materials are available on-line at (under the Dental section) to assist in

    complying with these best management practices. In particular, dental practices are encouraged to reference The Environmentally Responsible Dental Office: A Guide to Proper Waste Management in Dental Offices, which can be accessed through this web site.

Note: Note: New dental practices or relocated practices must file this certification form

     Withi within 30 days of startup.


    To complete this form, each dental practice, by location, should respond to each question and provide the additional information requested. If you can answer “Yes” to all of the questions, then your

    practice is following best management practices. A “No” response generally indicates that a best

    management practice is not being followed. If you answer “No” or “NA” (not applicable) to any

    question, please provide a brief written explanation below each question that describes why the management practice was not met, and any corrective action that will be taken, or why the management practice is not applicable.

    We suggest that you save the certification form on your computer. You can complete the form on your computer screen, then print and sign. Alternatively, you can print out the blank form and complete by hand.



    The Department will review self-certification forms that are submitted and will follow up with any incomplete forms submitted or non-filers. Periodic field visits will be conducted to verify compliance with BMPs and amalgam separator installation and operation. A high priority for field visits will be practices that have not filed self-certification forms.

    If you need assistance in completing the form or complying with these best management practices, please contact the Environmental Assistance Office at 800-974-9559.

    After completing the questions and signing the certification statement return the form by mail to:

    Vermont DEC

    Environmental Assistance Office (Dental)

     103 South Main Street The Cannery

     Waterbury, VT 05671-4911





    General Instructions: Place a check or “X” in the box for each question that indicates whether the best management is being followed (Yes), not being followed (No), or is not applicable to the practice (NA). If you answer “No” or “NA” to any best management practice, please explain in the space provided below each numbered item. If there are multiple sites for a dental practice, please complete one form per location.

Terms Related to Amalgam Wastes:

    ; Non-contact amalgam (scrap) is excess amalgam mix remaining at the end of a dental

    procedure. Many recyclers will buy this clean scrap.

    ; Contact amalgam is amalgam that has been in contact with a patient. Examples are extracted

    teeth with amalgam restorations, carving scrap collected at chairside, and amalgam captured by

    chairside traps, filters, or screens.

    ; Chairside traps capture amalgam waste during amalgam placement or removal procedures

    (traps from hygiene chairs generally do not contain amalgam).

    ; Vacuum pump filters or traps on wet seal vacuum systems (those using water) contain

    amalgam. Some recyclers will accept whole filters, while others may require special handling

    of this material.

    ; Amalgam capsules are the individually dosed containers of pre-capsulated dental amalgam.

    After use, the capsules may contain residual amalgam.

Best Management Practices for Amalgam Wastes



    1. Yes No NA All elemental mercury (free, bulk, or raw mercury) has

     been removed from the premises and sent for recycling. Comments:

    2. Yes No NA This practice recycles and intends to continue recycling

     all amalgam waste from this location, including amalgam

     from the separator(s), any amalgam scrap from screens,

     traps, or filters, and any scrap amalgam not fully used in

     dental procedures.


    Note: Use of dental amalgam by Vermont dental practices has been decreasing.

     When appropriate, use of alternative restorative materials to dental amalgam

     will reduce amalgam wastes and potential impact on the environment.

3. Provide the names and addresses of the recycling facility (ies) used by your practice to

    recycle its amalgam wastes.

a. Name


b. Name

     (if required), and pickup or shipping of amalgam waste. Comments:

    5. Yes No NA If any elemental mercury is present in the dental office,

     including mercury from historical use and mercury in any

     medical instruments, such as thermometers, a mercury

     spill kit is maintained on site and all appropriate staff

     trained in its use.


6. Yes No NA These practices are followed:


    ; Amalgam is not placed in a sharps container

    ; Amalgam is not placed in a red biohazard bag

    ; Amalgam is not discarded in the regular trash

    ; Amalgam is not disposed down the drain

    ; Excess amalgam is not removed from an amalgam well using a high-speed suction

    (vacuum) line.

    ; Extracted teeth with amalgam restorations are not placed in a red biohazard bag, but are

    recycled with other amalgam wastes in a disinfectant solution (such as glutaraldehyde

    or formalin), or as directed by the recycler.

    ; Used amalgam capsules are not placed in the regular trash but are recycled with other

    amalgam wastes.


    Disposable Chairside Traps (check NA and proceed to next question if only reusable traps are used)

Best Management Practices for Amalgam Separators

    By January 1, 2007, amalgam separators must be installed in all Vermont dental practices except for orthodontists, periodontists, endodontists, oral and maxillofacial surgeons, and any other dental practice that does not place or remove amalgam.

    Newly installed amalgam separators must be certified to the ISO 11143 standard for amalgam separators (the Vermont Department of Environmental Conservation maintains a list of certified amalgam separators).

In the event that a dental practice installed an amalgam separator prior to January 1, 2006,

    and that separator is not on the list of certified amalgam separators, the practice may continue to use that separator for compliance with these best management practices unless, in the opinion of the Department, the amalgam separator is not capable of achieving amalgam removal efficiencies equivalent to certified separators.

    15. Yes No NA This practice has installed an amalgam separator to

     service all of its dental chairs where amalgam is placed or

     installation information, inspection logs, and amalgam

     shipping records) are maintained for at least three years. Comments:


Best Management Practices for Conditionally Exempt Hazardous Wastes

Certain wastes generated by Vermont dental practices are regulated as hazardous wastes. The

    wastes identified in this section are exempt from regulation as hazardous provided specific

    conditions are met. For more information about the hazardous waste regulations that apply to

    Vermont small businesses, refer to the Conditionally Exempt Generators’ Handbook which is

    available on-line at:



    19. Yes No NA This practice has evaluated all of the wastes that it

     generates and determined which, if any, are regulated as

     hazardous wastes.


Note: Note: Typical hazardous wastes generated by dental practices include the following:

     - amalgam (contain mercury and silver);

     - lead foils and other lead-containing wastes; and

     - photographic fixer and film (contain silver)

     - universal waste: fluorescent lamps, mercury-containing devices, cathode ray

    tubes (TVs, monitors)

    20. Yes No NA Conditionally exempt and regulated hazardous wastes are

     not disposed of in the trash or down the drain.


Used X-Ray Fixer Solution

21. Yes No NA Used x-ray fixer solution is:

    ; Sent to a silver recovery facility that is authorized to accept and recycle this waste in the

    receiving state; or

    ; Sent off-site for recycling using a permitted hazardous waste transporter; or

    ; Reclaimed on-site using a silver recovery unit (see Note below); or

    ; Recycled through a municipal hazardous waste collection program.

    Note: Wastewater treated by a silver recovery unit may be discharged into the

    municipal wastewater treatment plant unless prohibited by the municipality. Dental

    practices connected to an on-site septic system should not discharge treated wastewater

    from silver recovery to that system. Consider bringing this waste to a municipal

    hazardous waste collection program.



Used X-Ray Developer and Cleaners

    Notes: Used x-ray developer, if not mixed with x-ray fixer, may be discharged to the

     municipal wastewater treatment plant unless prohibited by the municipality.

     Used developer should not be discharged to a septic system. Consider

     bringing this waste to a municipal hazardous waste collection program.
