Introduction
     The purpose of this manual is to help hospitals start mercury pollution prevention programs or accelerate
programs that have already begun. The U.S. Environmental Protection Agency and the American Hospital Asso-
ciation have committed to a voluntary agreement to virtually eliminate mercury waste in hospitals and health
systems by 2005, and are asking healthcare providers to join with us in this effort to help reach these environ-
mentally sound goals.
     There are many reasons why it makes sense for hospitals to reduce their use of mercury. For example, new
federal air and water regulations greatly reduce the amount of mercury that is allowed to be discharged from a
municipal wastewater system or an incinerator. In addition, the capability to measure mercury at lower levelsmakes
it easier for regulatory agencies to identify those who are not in compliance. As a result of these developments,
regulatory compliance costs are rising. By implementing the best management practices described in this
manual, you can reduce the level of mercury in the environment and avoid the need to increase your investment
in pollution controls and waste disposal.
     The manual offers general guidance on how to initiate a program and technical guidance for implementing
the program. The manual includes:

1.1 - Background on Mercury

    Mercury is a toxic metal that occurs naturally in the environment. There are both inorganic forms and organic
forms of mercury. As shown in Figure 1 below, many of the forms of mercury circulate in the environment, moving
from land or water to air and back again, and the forms of mercury may change from one to another as they
circulate.
    Human activities significantly redistribute mercury and release it into the environment. They allow mercury
that was formerly unavailable to the biosphere* to be mobilized and carried to new areas via air and water. In
the water or soil, microorganisms can convert inorganic mercury into a more toxic organic form, methylmercury.
Fish take in methylmercury from their diet and from water passing over their gills. They bioaccumulate the
methylmercury in their bodies because the rate of intake of methylmercury is much greater than its elimination.
Methylmercury bioaccumulates in the tissues of a fish throughout its lifetime. It can build up to high levels in
predator fish at the top of the aquatic food chain -- levels that are tens of thousands to millions of times above
the level found in the surrounding water. Fish with high levels of methylmercury may be caught and consumed by
humans, waterfowl or other wildlife.

The protocol might include the following instructions:

  1. If the sphygmomanometer is mounted on the
     wall, the entire apparatus must be removed
     and taken to a safe workspace to refill. Do
     not attempt to remove the mercury until
     you have removed the sphygmometer from
     the wall and taken it to a safe workspace.
  2. Place the sphygmomanometer to be refilled in
     a clear plastic bag and seal the bag. Do not
     use a red bag or biohazard bag.
  3. Mark the bag: “  CONTAINS MERCURY.”
  4. Place the bag in a plastic basin to contain
     spills while transporting to the area where the
     sphygmomanometer is to be refilled.
  5. Wear appropriate protective clothing and
     work within a hood to provide ventilation.
  6. Make sure the sphygmomanometer is resting
     on its side when you remove the mercury-
     containing tube inside. Pressing the lever on
     older sphygmomanometers will cause the
     glass mercury tube to be released from the
     bottom of the apparatus. The glass tube is

3.6.2 - Recycling/disposal of mercury-containing
laboratory chemicals

      Train laboratory staff on the proper use, handling
and disposal of hazardous materials, and the impor-
tance of keeping mercury out of wastewater. Make
the staff aware of laboratory products that are known
to contain mercury. To minimize the amount of haz-
ardous waste generated, keep laboratory chemicals
ready for recycling or disposal separate from each
other. Do not mix them!
      Mercury-contaminated waste should be collected
and disposed as hazardous waste. Check with your
local sewer district for information about the proper
disposal of mercury-contaminated rinse water.
      For plumbing in lab areas and dentist offices, there
filtration divices available that can be attached to the
plumbing. These devices separate and collect in-so-
lution mercury from wastewater and can save time
and money. Check the list of Mercury Recyclers in
Appendix C for contact information.
      Check for unused, nonessential mercury-contain-
ing chemicals in storage areas and dispose of them
                                                s
as hazardous waste. Contact the hospital’ hazard-
ous waste management coordinator about transport-
ing the chemicals to the designated hazardous waste
collection point. Protective clothing, carpeting or de-
bris that is contaminated with a mercury compound
should be managed in accordance with U.S. Environ-
mental Protection Agency and state regulations.

tory contacts.)

     A mercury thermostat probe may also be part of
the main temperature-controlling gas valve. In this
application, the probe is in the air or water that is
being heated and is not directly in contact with any

dryers, water heaters and space heaters.

of a thermostat probe, obtain this information from
the manufacturer.

3.14 - Industrial Thermometers

    Air and water heating and cooling systems employ thermometers to allow monitoring of the
systems’  performance. Many of these thermometers are mercury in glass.

3.14.1 - Recycling/disposal of mercury-containing industrial thermometers

    It will be necessary to properly recycle or dispose of mercury industrial thermometers if the
hospital is retrofitting with mercury-free thermometers or if it is replacing an entire heating or cool-
ing system that employed mercury thermometers. The thermometers should be packed for delivery
to the designated hazardous waste collection point in a tightly closed container and in a manner
that will prevent breakage of the thermometers. Contact the hazardous waste management coor-
dinator for detailed instructions.

  • Laboratory manometers used by biomedical
      engineers to calibrate other instruments in
      the hospital
  • Barometers
  • Sphygmomanometers (see the section on

3.17.2 - Sample Mercury Spill Response Plan

    Healthcare Without Harm, a non-profit environmental organization, has developed the following guidance
for dealing with mercury spills. You may wish to incorporate these suggestions into your mercury spill re-
sponse training and planning.

     1. Immediately after a spill, keep all people and pets away from the spill area. To minimize
     the amount of mercury in the air, turn off any heaters and turn up any air conditioners. This will slow the
     mercury from vaporizing. Ventilate the area by opening windows. If possible, keep the windows open for
     at least two days to allow any residual mercury to leave the building.
     2. Never use a regular vacuum cleaner to clean up mercury. The mercury will contaminate the
     entire vacuum and the heat from the vacuum will accelerate the mercury to evaporate into the air, and
     the vacuum will also blow mercury-tainted air through the room. The only type of vacuum appropriate
     for cleaning up mercury spills is a specialized mercury vacuum with an activated carbon filter to absorb
     and contain the mercury vapors. Ask your State contact for more information if you want to purchase
     one of these vacuums. Also, never use a broom to clean up mercury. It will only block the mercury up
     into smaller beads and will contaminate the broom.
     3. Assemble the necessary supplies before attempting a clenaup. These include gloves, an
     eyedropper, and two stiff pieces of paper or cardboard, two plastic bags (size depends on the size of the
     spill), a large tray or box, two labels (to put on the plastic bags), a marker or pen, duct tape or packing
     tape, a flashlight, and a wide-mouthed container with a lid. Remember that any tools used for cleanup
     should be considered contaminated and should be disposed of with the mercury.
     4. Do not touch the mercury. Remove all jewlery and watches from your hands, as mercury will
     bond with the metal. Put on gloves (preferably rubber gloves or a non-porous equivalent) to minimize
     the contact with mercury. Use the flashlight to locate all of the mercury. Mercury is a reflective element
     and the mercury beads can easily be located with a bright light.
     5. Clean up the spill with procedures appropriate to the type of surface in the spill area
     • On a hard surface or tightly woven fabric, use stiff-backed paper to push the beads of mercury
     together. If you do not have a tray or box nearby to catch any additional spills, use the eyedropper to
     suction the beads of mercury. If you are working over a tray (to catch spills), lift the beads with the
     beads of mercury with the stiff paper. Carefully place the mercury into a wide-mouthed container. Pick
     up any remaining beads of mercury with sticky tape and place the contaminated tape in a plastic bag
     along with the eye-dropper, stiff paper, and gloves. Label the plastic bag as “                     .
                                                                                      MERCURY WASTE” Place
     this bag and sealed container in the second plastic bag and also label this bag “  MERCURY WASTE” Call.
     your State agency to determine appropriate disposal regulations and locations.
     • On a carpet or rug, the mercury-contaminated section should be cut out with the scissors. The cut
      section, along with all of the cleanup items (scissors included), should be placed in a plastic bag. Label
     the bag as “   MERCURY WASTE”and call your State agency for appropriate disposal regulations and
     locations.
     • In a sink of water, mercury will sink to the bottom. Remove as much water as possible without
     disturbing the mercury. Use the eyedropper to recover the mercury. Place the mercury into a wide-
     mouthed container, close the lid and seal it with tape. Label the bag as “      MERCURY WASTE”and call
     your State agency for appropriate disposal regulations and locations.
     • In a drain, mercury will settle to the bottom and get caught in the sink trap. Place a box or tray
     under the pipes to prevent any further spills. Remove the trap and pour the contents into a large-
     mouthed container. Close the container lid and seal with tape. Label the bag as “       MERCURY WASTE”
     and call your State Agency for appropriate disposal regulations and locations.

3.17..3 - Mercury spill response preperation

      Mercury spills are very disruptive. A large spill will
require removing the patient from the room during
cleanup. The room would have to remain vacant un-
til it is ensured that there is no longer mercury vapor
in the air.
      Be prepared for a spill in any area of the hospital
where mercury-containing devices are used. Have a
mercury vacuum cleaner or mercury spill kit readily
available to consolidate spilled mercury and limit the
amount of mercury released into the air.
      The cleanup of mercury spills must be performed
by specially trained staff members. Carry out simu-
lated spills and cleanup as part of training.
      Create a formal mercury spill policy for the hospi-
tal. Consider the following factors when developing
the policy:
   • Round-the-clock availability of a competent
         staff person, trained for mercury spill cleanup
   • Protective equipment and clothing for cleanup
         staff
   • OSHA requirements
   • The circumstances when the patient(s),
         visitors and staff should be evacuated from
         the area before cleanup
   • How to determine when a room is “         clean
         enough”to reoccupy
   • Type of flooring (linoleum, carpet, etc.)
   • Determination of the type of equipment to be
         used for the size and type of spill
                        s
   • Manufacturer’ instructions for the equip-
         ment to be used
   • Ultimate waste disposal, which may depend
         on the cleanup method
   • Preparation of an incident report that de-
         scribes the spill, the cleanup method used,
         unusual circumstances, and follow up
   • Mercury spills during a medical procedure
   • Posting of “     Who to Call”signs in case of a
         spill in areas where mercury is used and near
         mercury recycling receptacles.

                          containing items are stored
should be tested periodically using a mercury vapor
sniffer.
     Even after most uses of mercury have been dis-
continued in the hospital, mercury-containing prod-
ucts may still be in storage from past uses. All hospi-
tal units should check storage areas for old, dam-
aged or outdated equipment. (See Appendix A and
Appendix B for lists of possible mercury-containing
products in the hospital.) If mercury-containing prod-
ucts are found, contact the hazardous waste man-
agement coordinator. After the removal of the mer-

ther assistance in finding alternatives. The most ef-
fective way to replace mercury-containing pharma-
ceuticals and lab chemicals is is to replace them over
time by adopting a mercury free purchasing policy.
This type of policy directs suppliers and vendors that
all such products should be mercury-free chemicals
whenever possible, and to alert you when new mer-
cury-free substitutes become available.

     Identifying the total cost of a product to a facility
or to the hospital can be a very effective way to iden-
tify opportunities for cost-effective toxic reduction.
Mercury thermometers are an excellent example.
The purchase cost of a mercury thermometer is very
low. However, the safest disposal for elemental mer-

and risks to human health can be difficult to quantify.
Exposure to many persistent toxic substances and
other health risks make it difficult to isolate the ef-
fects of mercury on humans and wildlife, except in
cases of gross exposure. Ironically, the more wide-
spread the toxic substance, the more difficult it is to
isolate chronic exposure because traditional meth-
ods of study depend on exposure differences.

      Benefits of reducing pollution can be difficult to

    However, it is important to recognize that there
are serious health effects associated both with
consumption of fish contaminated from mercury
and with direct exposure to high concentrations of
mercury. See Chapter 3 for more information on
health effects.

    Costs to the environment and society are not
generally included in the purchase price of products
or equipment containing persistent toxics such as
mercury. Environmental liabilities of current and
past practices are usually ignored and not ac-
counted for on financial statements.

4.5 Mercury Cost Savings Worksheets
    The following worksheets were put together to assist hospitals in determining the costs or
savings of eliminating mercury in their facilities. For the first worksheet, a sample is provided for
reference, followed by a blank worksheet for your personal use.

    The sample worksheet compares the costs of a mercury and a non-mercury mobile sphygmo-
manometer. The analysis shows that, although the initial purchase price of the mercury sphygmo-
manometer might be the same or slightly higher, when clean-up estimates and low disposal cost
estimates are included, the non-mercury sphygmomanometer becomes the more cost effective
option.

    Caluclations on the Sample Worksheet use the following methodology:

    Handling of mercury sphygs = 10 hr * $15/hr = $150

    Spill Clean-up includes the cost of the clean-up kit plus the time required to train staff.
    If an external contractor is required to clean up a spill, costs increase by 4 or 5 times. the cost
    of using internal staff.

    1 spill per year:

    Spill cleanup Kit = $5 - $300

    Staff time for cleanup = $10-$15/hr

    Contractor = $20-$25/hr * 1-5 hours = $10 - $125

    Personal Protective Equipment for Staff = $200-$500 * 2-5 Employees = $400 - $2500

    Initial Training for spill cleanup = $20/hr-$25/hr for trainer * 3 hours = $60-$75
                                    $10-15/hr for employees * 2-5 employees * 3 hours= $60-$225

    Hazardous waste disposal of PPE and cleanup materials = $100 - $500 per spill

    Total Net Operating Cost or Savings : $ 795 - $3875 per spill

    Total Capital Costs for Aneroid Sphygs = $7350 - $9840

    Payback Period (in years) = ($7350-$9840) divided by ($795 - $3875) =.02 to 12.3 years

not held responsible.
     Even when only the internal costs were consid-
ered, it was shown that the use of mercury-free
equipment can save facilities money.
     The key is in identifying all of the costs associ-
ated with the usage of mercury equipment and
attributing those costs to the equipment itself
rather than letting those costs get lost in overhead
accounts.

       9. Hazardous waste, including mercury,
     was being collected via a formal program and
     shipped to off-site facilities for disposal.



  Areas of concern included:

  • Initial testing of the wastewater effluent showed mercury levels of 0.8 ppb. This would be required to
    be reduced once the Great Lakes Water Quality Initiative standards were adopted.
  • Existing policy was sometimes decentralized. Gathering information was sometimes difficult and the
    results from questionnaires or other queries could be conflicting. There was no mercury
    thermometer take-home policy.
  • Substitutes for mercury are still to be identified for thermometers in some applications at SMH.
  • Mercury as a contaminant needs to be addressed for various lab reagents and cleaning compounds.
  • Mercury pollution prevention training needs to be incorporated into as many pre-existing training
    programs as feasible.
                                                                 s
  • Contact amalgam (amalgam that has been in the patient’ mouth) was being considered regulated
    medical waste.
  • Mercury thermometers from isolation patient care rooms were being considered regulated medical
    waste.
  • Nursing staff surveys indicated that not all staff understood fully what to do with used mercury
    thermometers or with mercury in the event of a spill, in spite of existing policy and training. Similar
    knowledge gaps were also discovered in other areas of the institution.


     This information led to Lesson 2: In spite of policy or training, there are always items that can fall
 through the cracks. It pays to compare practice with policy in order to identify and solve a problem.

    A Mercury Work Group was established at SMH. It included representatives of:
       Administration                         Housekeeping
       Clinical Laboratories                  Medical Engineering Laboratory

       Environmental Health and Safety        Stores
       Facilities

                s
    The Hospital’ mercury pollution prevention program accelerated after the formation of the Work
    Group in the following areas:

    Elimination of mercury
    • Non-mercury thermometers were identified and tested in some of the areas where no substi-
       tute was previously identified.
    • Some nursing units no longer give out take-home thermometers.
    • Laboratories were surveyed to verify that mercury was still no longer being used. If discov-
       ered, the use and disposal route were determined.
    • Mercury sphygmomanometer replacement was tracked more closely and the rate of replace-
       ment increased.

    Education
    • Mercury-specific training was included in the annual required training video. A specific test
       question about mercury disposal was included. Also a new segment about mercury was added
       to the Facilities Operations and Maintenance training presentation.
    • Educational packets were created for nursing managers and the housekeeping supervisor.
    • A mercury survey for nursing personnel was developed that was intended to be used both
       before and after training. (See survey at the end of this case study.)
    • Articles were written and published in SMH/University newspapers that pointed out some of
       the issues and concerns with mercury.
    • Designated containers for mercury thermometer disposal were placed in the “      soiled utility
       rooms.” The containers are marked with a specially designed sticker (see end of this case
       study).
    • Specially designed stickers (see end of this case study) were placed on or near red bag con-
       tainers to discourage the placement of a mercury thermometer there.
    • An overview of the mercury pollution prevention program was given to department heads at a
       meeting. The overview included the reasons for the program and successes that have been
       achieved so far.
    • A pamphlet on “    Mercury Management for Nursing Units”was distributed to the nursing per-
       sonnel (see end of this case study).
    • A plan was developed to display educational materials about mercury for the general public in
       the corridor to the Hospital cafeteria.

Chapter 5

      Policy
      • Nursing Policy was updated to cover mercury thermometers from isolation units (disinfection
         prior to collection).
      • Policies about mercury have been collected from various departments and are being consoli-
         dated.

      Best management practices
      • A disposal container for mercury-containing electrical parts, such as switches, was placed at
         the location where the replacement equipment is distributed.
      • A protocol for the care, use and recycling of dental materials was implemented in the Depart-
         ment of Dentistry and Eastman Dental Center.
      • The Hospital entered into an agreement with the Monroe County Department of Environmen-
         tal Services that establishes best management practices to reduce mercury loading from the
                                  s
         Hospital to the County’ wastewater treatment system.

The Hospital has also:

• Discontinued the use of mercury thermometers,

• Discontinued the use of mercury stains in order

5.3 - Case Studies of Mercury Pollution Prevention Measures in Michigan Health Care Institutions

    The following information is adapted from: Michigan Mercury Pollution Prevention Task Force (1996),
Mercury Pollution Prevention in Michigan: Summary of Current Efforts and Recommendations for Future
Activities.

    As part of the compilation of the Mercury Pollution Prevention in Michigan report, a health care group was
formed to identify the uses of mercury in hospitals and alternatives for those uses. Several hospitals were
contacted regarding the topic of mercury pollution prevention measures currently underway in their institu-
tions. While there are measures that must be adhered to under federal and state laws, for example training
on spill prevention and management, many of these health care institutions go beyond mere compliance with
existing law by educating a broad spectrum of employees in the proper procedures in handling mercury spills
and minimization of mercury use. The following are examples of some of the ongoing activities.

   Introduction

    This case study will emphasize reduction of mercury in a Clinical Laboratory setting, but could be imple-
mented for any toxic material. To reduce use of any toxic material you first have to recognize that you have it.
Once you identify the material or materials that you need to reduce or eliminate from your facility, you are really
faced with three questions:

   1) Where do I begin?
   2) How do I interpret and utilize results of the investigative process?
   3) How do I reduce or eliminate the material?

   Newton-Wellesley Hospital began to look at sources of mercury in the laboratory in order to comply with its
water discharge permit to the local Water Treatment Plant (Massachusetts Water Resource Authority). This
paper will outline the process followed and present the results of chemical testing (performed by Matrix
Analytical, Inc., Hopkinton, MA) and subsequent mercury reduction activities.

   Activities Performed at Newton-Wellesley Hospital to Identify Sources of the Mercury Contamination
Problem:

    1. We identified all reagents used in the department. A database was established using MSDS information
and the quantity discharged by the lab. The chemicals were then screened for mercury containing substances.
The testing results are provided on the following pages.
    2. We segregated waste by department and screened the waste for mercury. First we placed large drums
for collection of all waste in all departments. The drums were used to eliminate the possibility of the pipeline
as a source of mercury. Aliquots from the drums were tested for mercury. In retrospect the ideal situation
would have been a laboratory that is plumbed to segregation of waste streams once plumbing is determined
to have below quantitative levels of detectable mercury.
    3. All laboratory waste streams which tested positive for mercury were then segregated by bench. Collec-
tion stations were placed on every bench and aliquots of those wastes were submitted for analysis. The bench
areas from which the mercury-containing waste came were identified. The MSDS for reagents used on these
benches were scrutinized, and the manufacturer was contacted for additional information. Suspect reagents
were tested for mercury content.

expressed in parts as 1 ppb (part per billion).

    MSDS reportable limits: Since heavy metals are
considered to be carcinogens or potential carcino-
gens, the concentration limit set by OSHA for
manufacturers to disclose their presence is set at
0.1%. This is equivalent to O.l g/100ml or O.Ol gm/
L or 10 mg/L. Most manufacturers outside of
Massachusetts therefore feel that they have
exceeded their responsibility by reporting the
presence of mercury when it exceeds the EPA limit
of 1 ppm or 1 mg/L, as they legally only have to
include it on the MSDS when it exceeds 10 mg/L.
This is important to recognize when dealing with
manufacturers.

     In evaluating a product, we must establish if
the product is certified mercury free or if the
manufacturer has attempted to test only to the
limit set nationally. A company may insist that the
product does not contain mercury because the
company did not detect its presence at a level of
10 ppm or 1 ppm or higher. It is therefore very
critical to ensure that a product to be used in this
hospital has been tested to detect mercury at
levels at or below 1 ppb , not 1 ppm.

Below quantitative limits (BQL):

     This means that the results of the testing
demonstrated that there was no mercury detected
at the lowest concentration that the laboratory’s
method for testing for the concentration of mercury
in that particular specimen could detect. When BQL
is written you need to know what the limits of
detection are for the analysis that you performed.

Continued Testing and Discussion

    Histology:
    Embedded tissue that had been fixed in VIP or other known mercury containing compounds continued to
leach mercury and contaminate other areas of the histology laboratory. Water baths at microtome stations are
the first solutions into which fixed tissues were placed for processing and staining. We should find alternatives
for mercury containing stains.

    Microbiology:
    Parasitology stains and preservative contain mercury; alternatives need to be found. Stains need to be
tested and replacements for mercury-based reagents, PVA transport system and preservative need to be
found.

    Hematology:
    Few problems with mercury, stains and reagents not a problem.

    Chemistry:
    Testing results from the follow-up of the 8.8 mg/l found in the electrophoresis waste:

    Electrophoresis Reagents:

Toxic Waste Management Program

    The analysis and testing done as a result of the mercury problem led to the establishment of a Hospital
Mercury Reduction Policy (listed below), a method for tracking and following progress of Mercury containing
reagents, and establishment in the laboratory of a Waste Reduction Program.


Mercury Reduction Policy
    Purpose: To enable the Hospital to meet mercury level standards established by the federal and state
environmental protection agencies and the Massachusetts Water Resources Authority (“                   )
                                                                                              MWRA” and require-
                        s
ments of the Hospital’ Sewer Use Discharge Permit.
    Background: Mercury is a hazardous substance under state and federal environmental laws. The Hospital’         s
Permit and MWRA regulations prohibit the discharge of mercury into the sanitary sewer system. Pursuant to its
permit, the Hospital must monitor its discharges into the sewer system of several elements, including mercury.
Among other enforcement actions, the MWRA may assess monetary penalties for discharges which exceed the
standard. Neither government nor private agencies have been able to identify a process by which mercury can
be successfully removed from a water stream. The hospital therefore, must attempt to prevent mercury from
entering its waste water stream in order to protect public health and to avoid penalties.
    *It is important to note that since the time this policy was drafted the hospital has identified and is testing
a technology that is producing preliminary results which look excellent for removing the trace mercury from the
waste.
    Policy Statement: (Note: This policy was developed for the specific use of Newton Wellesley Hospital; no
representation is made that it is applicable to any other institution). Mercury containing products and pro-
cesses shall not be used in any manner on the Hospital campus, including within the Hospital buildings and
medical office buildings, unless no reasonable alternatives, as determined by Hospital Administration, are
available. When use of a mercury containing product is permitted, measures shall be taken to avoid introduc-
tion of mercury into the sanitary sewer system.
    Applicability: Compliance with this policy and its procedures is a condition of employment and a condition of
the exercise of clinical privileges or the use of any property located on the Hospital campus. The Hospital
reserves its right to take any and all actions, including to seek injunctive relief, to prevent violation of this
policy by any party.

Procedures

                     s
     I. The Hospital’ Departments of Engineering, Environmental Services, Purchasing, Pathology, Radiology,
and Safety shall work together to identify product(s) or process(es) containing mercury currently in use on the
Hospital campus and to identify acceptable alternatives. A list of such products/processes and their alterna-
tives shall be presented to the Safety Committee which shall arrange for its distribution throughout the Hospi-
tal community.
     II. When mercury containing products or processes are identified, the manager(s) for the department(s)
using such products/processes shall develop a plan to include a.) procedures for the prevention of disposal of
any mercury into the sanitary sewer system, b.) a timeframe for the elimination of the use of these products/
processes or, in the alternative, the rationale (including information required below at IV) for continued use of
such products/processes. The manager(s) shall present the plan to the Safety Committee for review and
approval.
     III. The Safety Committee shall review all mercury use plans and may approve the plans as submitted or
with modification.
     IV. Managers of departments using mercury products/processes shall maintain a readily retrievable log of
the mercury-containing products/processes, the approved use(s), the alternatives considered, the reasons
such alternatives were deemed unacceptable, and a time frame for reconsideration of available alternatives.
     V. In the event of a mercury spill, employees and physicians shall follow the procedures of Safety Policy
#28-8, Handling of Mercury Spills. Managers shall report such spills to the Safety Committee for review.
     VI. All employees and physicians shall prevent the disposal of mercury into the sanitary sewer system and
shall refrain from using mercury-containing products/processes on the Hospital campus unless such use has
been approved in accordance with this policy.
     VII. All employees and physicians are encouraged to present suggestions for eliminating mercury containing
products or processes from the Hospital campus to the Hospital Safety Committee.

Hazardous Waste Management Report, Pathology Department, January 1998

    We continue our effort to comply with federal, state, and local hazardous waste requirements
and to provide strong pro-active leadership in hazardous waste reduction. A major focus of the
Pathology Department in 1997 was on the elimination of mercury and a reduction of toxic chemi-
cals at the point of production. Our goal was to improve the workplace, help the environment and
at the same time effectively cut chemical purchase and disposal costs.

Toxic use reduction was accomplished by:
1.    Reduction in Chemical purchases and better inventory control, using the Meditech Chemical
      Database.
2.    Purchase of equipment that utilized small reagent volumes and generated minimum
      hazardous waste.

4.    Replacement of manual staining procedures in Histology with kits continues with elimination

5.    Increased employee training in hazardous materials management and mercury source
      reduction.

    In January of 1997, training in hazardous waste management emphasized looking at chemical
purchases with emphasis on actual need not restocking, cost of discarding expired reagents, and
hazards of having a large inventory of chemicals. Chemical inventories were included as part of the
monthly safety audit of each area and employee knowledge of chemical hazards were assessed
during the routine safety inspections. As of January of this year the amount of hazardous chemi-
cals we were expiring had decreased by half and safety inspection reports showed an increase in
chemical safety knowledge.

     Employee training in hazardous materials management and implementation of several chemi-
cal disaster drills in the department have heightened employee awareness of their role in handling
spills and in controlling chemical waste. The disaster drill reports showed a marked improvement
since 1996.

    New instruments and procedures are now evaluated for the type and volume of chemicals
used and for the impact they will have on our hazardous waste reduction policy. We have seen a
reduction in flow volume of nonhazardous waste in the laboratory of 4500 gallons per month
average in 1998 to 4000 gallons per month in 1999. During the same time frame, the laboratory
has seen an increase in workload volume of as high as 21%.

    The total volume of hazardous waste drums generated per week showed no change from
1997, however, the workload volume in Histology alone showed a 23% increase. The fact that we
were able to keep our hazardous waste volume at the same level even with an increase in testing
volume was due mostly to the reduction in volume of reagents used, and a concerted effort by the
employees in Histology to conserve and reduce toxic waste generated.

    To comply with the Mercury Reduction Policy, all waste streams in Pathology continue to be tested for
mercury; sources of mercury identified, and alternative-products continue to be actively sought. As an
active participant in the MASCO (Massachusetts Academic and Scientific Community Organization) Mercury
Workgroup, we have taken a leadership role in developing protocols for toxic waste management, identify-
ing effective pretreatment technologies, and ultimately reducing wastewater volumes. The Pathology
department is continuing to evaluate formaldehyde and xylene recycling systems. This would significantly
reduce the hazardous waste volume sent out each week. We have looked at several excellent, small, safe,
and cost effective systems in use in area hospitals. Space and personnel requirements are presently being
evaluated by the department.

    We continue to seek methods which will offer quality results with minimal chemical exposure and waste
production. The ultimate goal is to utilize technology that eliminates employee exposures and toxic waste
generation.

Addendum July 1998

    Mercury testing in Microbiology revealed a mercury contamination of the sink and staining racks. The
sink is on order and staining racks have arrived.

    Milligrams per kilogram or mg/kg equals mg/1000 g of the mixture. This is similar to mg/L as a measure-
                       s
ment of a substance’ concentration; however, mg/kg is not volume based but rather based on the specific
gravity of the waste mixture. Expressing concentrations in these terms would eliminate the existing situation
where concentration of mercury detected is dependent on the amount of diluent present. In other words,
hospital A and hospital B may have the same amount of mercury discharge, but if hospital A has a much

    With mercury filled Miller Abbott tubes there is
also a potential concern that the sac with mercury
can be disconnected when being removed from the
patient. This poses both medical and liability issues.

    The cost of the tracking system could be
eliminated in addition to hazardous waste costs for
disposing of the mercury from Miller Abbott tubes.

    Overall environmental impact

    DHMC purchased approximately 24 a year. For
each Miller Abbott tube issued, a one pound bottle
of mercury would be issued with the tube. The tube
was filled with as much mercury as needed for the
procedure and the remaining mercury needed to be
tracked to ensure it did not end up in the waste
stream. Typically about a half a pound of mercury
was used per procedure. A rough estimate of the
amount of mercury no longer needed due to the
replacement would be 12 pounds of mercury a
year.

    In 1997, the remaining mercury in the waste-
water appeared to be coming from the Hospital
laboratories and laundry services. Reagents and
bleach are the suspected sources. These products
are being investigated and, where possible, alterna-
tives will be substituted.

    Historic sources are also under investigation.
Mercury from items such as broken thermometers
may have been disposed of down the drain in older
buildings. The mercury accumulates in waste traps
and discharges in small amounts each time water
is used. Traps in nursing stations and in the labs
are being cleaned and inventoried as part of the
reduction effort.

    WLSSD continues to work with St. Mary’ on s
mercury reduction and has initiated similar projects
with the other hospitals in Duluth. These following
actions are essential first steps for any hospital
beginning a mercury reduction project:
    1. Discontinue the purchase of
mercury-containing equipment such as thermom-
eters, sphygmomanometers and gastrointestinal
equipment, and substitute mercury-free alterna-
tives for existing equipment.
    2. Discontinue the policy of sending mercury
thermometers home with new parents (this prac-
tice is illegal in Minnesota).
    3. Institute recycling programs for
mercury-containing lamps and batteries.
    4. Implement a mercury-free purchasing policy
and request all vendors to disclose mercury con-
centration on a Certificate of Analysis. Products
with no mercury or low mercury can then be se-
lected for purchase.

              s
     Children’ Hospital of Wisconsin continues to
pursue hazardous materials and waste reduction
initiatives and pollution prevention strategies. Its
ideas and successes are networked through
member hospital associations on the local and
national level, and through the University of
Wisconsin-Extension, Solid and Hazardous Waste
Education Center.

    In conclusion, fundamental to the success of
these and all waste reduction programs are: top
administration support, employee participation,
education and training, good housekeeping and
materials management, auditing/measuring/
monitoring the program, then reporting achieve-
ments and successes to all those engaged in this
partnership. Also essential to hazardous materials
and waste reduction are, assuring proper handling
and disposal, selecting safer alternatives and
incorporating any changes into the overall hazard-
ous materials and waste management program.

90,000 employees and 10,000 group practice physicians, Kaiser Permanente’ integrated health delivery
system owns and operates 30 hospitals and 360 clinics.

    Kaiser Permanente purchases about $5 billion of commodities and services annually. According to its
calculations, Kaiser Permanente generates 70 million pounds of waste (solid and infectious) each year.

                          s
    Kaiser Permanente’ Resource Conservation Management (RCM) program is a two-year-old initiative at
the national level to integrate issues surrounding supply chain management, environmental health and safety
(EH&S), and facilities management. The goals of the initiative are to minimize waste, prevent pollution, con-
serve natural resources, reduce costs, and develop model environmental protection practices within the
health care industry.

    For additional detail on Kaiser Permanente’ procurement practices, see profile, Appendix A.

Issue and actions to date: Mercury minimization

   Since October 1998, Kaiser has had a mercury minimization policy for national contracting and procure-
ment. RFPs and terms and conditions state:
    Kaiser Permanente is committed to minimizing the amount of mercury utilized in its operations, and
    desires to avoid the acquisition of products that contain mercury whenever feasible alternatives exist that
    do not compromise patient care.
    Potential vendors or suppliers submitting contract bids must identify any mercury contained in the product
they are offering and indicate if a “feasible”mercury-free alternative is available. This policy predates the
mercury reduction commitment of the EPA/AHA voluntary partnership.

   Under this policy, Kaiser Permanente has pursued mercury reduction principally through three procure-
ment items:

·   Thermometers — Switch to digital thermometers. Kaiser Permanente has implemented a national
    standard specifying that only mercury-free thermometers shall be procured; mercury-free
    thermometers have almost entirely replaced the previous stock of mercury thermometers. (One
                                                                                 cold kits”given to
    exception is that mercury thermometers are included in the existing stock of “

    patients for home care. When the 1998– stock of cold kits is depleted, mercury-free kits will be
    procured.)
·   Sphygmomanometers (blood pressure measurement devices) — Mercury-containing devices are no
    longer being procured; aneroid alternative devices are being procured instead. While some facilities
    have completely replaced their mercury sphygmomanometers, most are doing so gradually. When
    facilities are remodeled or renovated, any existing mercury sphygmomanometers are replaced.

Chapter 5
·   Fluorescent lamps — Kaiser Permanente has signed a national contract with a fluorescent
    lamp recycler. Large-scale lamp disposal associated with facility lighting efficiency retrofits fall
    under this contract; Kaiser is attempting to divert lights replaced in the course of normal
    maintenance to its recycler as well.
    (See discussion of mercury as a component of the hospital waste stream in Section 3.3)

Decision-making

                                                  s
    Senior management in Kaiser Permanente’ National Purchasing Organization considered the
mercury reduction decision a clear one — mercury was an obvious bad environmental actor, clear
product or practice alternatives existed for the largest mercury sources in the waste stream, and a
national procurement policy would formalize policy which was in many cases being pursued in a de
facto manner by individuals responsible for different procurement areas, both nationally and at
specific facilities.

    Product procurement areas targeted so far are straightforward — mercury-free substitutes were
previously demonstrated and posed no patient care issues. Further mercury reduction is likely to be
more difficult, and involve far more debate and conscious weighing of tradeoffs. The mercury free
alternatives available for product classes such as fixatives, reagents, vaccines, and dental amal-
gams are less proven, do pose efficacy issues, and for these reasons are controversial in many
cases.

Role of EA — contributions, considerations

                              s
   Underlying management’ willingness to make the mercury reduction commitment was an aware-
                                                                                                   s
ness that the mercury-free alternatives and practices (which would address 95% of Kaiser Permanente’
mercury waste stream) would not result in insupportable costs.

                         s
    Kaiser Permanente’ Resource Conservation Manager did employ EA principles in preparing a
                                                                                             s
supportive analysis of the mercury reduction decision. This analysis and Kaiser Permanente’ expe-
rience with changes in procurement cost structures arising from mercury-reducing product and practice
changes are presented below. They are of interest for two reasons:

·   They provide an example of the application of EA principles, and
·   They clearly illustrate that the hard cost consequences of these waste reduction decisions
    cannot be captured simply by assessing differences in unit purchase costs.
    In addition, they point to the type of analysis which may be necessary for situations in which
tradeoffs between alternative products and practices must be more seriously assessed.

Avoided costs for mercury-containing devices (thermometers and sphygmomanometers)

                                          Use of mercury-containing devices necessitates staff spill/exposure
                                          training, an estimable cost.

                                          Further, even given staff training, careful use and appropriate spill

                                          the possibility of fines from facility inspections or spill incidents. The
                                          probabilistic costs of mercury-related penaties were estimated using
                                          representative statutory and regulatory penalties multiplied by the
                                          probability of a fine being assessed for any particular voilation.

Chapter 5
Changes in per-unit purchase costs (thermometers and sphygmomanometers)


    The avoided costs detailed on the previous page are essentially changes in lifecycle costs asso-
ciated with the products not reflected in their purchase prices. Movement to mercury-free alterna-
tives also changed unit purchase costs and cost structures:

     Thermometers. Mercury thermometers are purchased, used for some expected number of
cycles, and subsequently disposed of, usually when broken. Yearly acquisition costs are thus essen-
tially determined by:

   unit price * (number of units required to replace breakage) + (number of units required to meet
expansion needs, if any)

    An important point, however, is that the purchase of a mercury thermometer almost necessarily
incurs the cost of a spill kit/spill response incident at some future point. At the least, it incurs the
incremental cost associated with disposal of the thermometer as hazardous waste.

    Digital thermometers themselves, on the other hand, are provided at no initial cost by the manu-
facturer. Each use of the thermometer, however, requires a sterile, disposable cover. These covers
are purchased on a per-unit basis.

    The cost structure of the two thermometer alternatives is thus quite different. Digital thermom-
                                         pay             ).
eters incur a clear cost with each use (“ as you go” When treated as a current expenditures

    Sphygmomanometers. The traditional blood pressure device measurement device registers
pressure via a mercury column; at $230/unit, the aneroid alternative is significantly more expensive
to purchase on a unit basis. When associated lifecycle costs are included (including the avoided cost
categories detailed in the table above), total costs per unit drop to about 1/3 the total costs of the
mercury unit.

Cost considerations: lighting

    Kaiser Permanente has a facility lighting upgrade program targeted at achieving energy effi-
ciency gains, with resulting cost savings and environmental benefits. Generally, the program focuses
on upgrading existing fluorescent systems with more efficient bulbs and ballasts. The upgrade pro-
gram follows EPA Green Lights program protocols2. Rather than focus on procurement of “      environ-
mentally preferable”lamps — a problematic determination (e.g., what is the tradeoff between (be-
cause fluorescent systems are more energy efficient, but contain mercury) — Kaiser Permanente
has focused on proper end-of-life treatment of lamps.




  92            MERCURY WASTE VIRTUAL ELIMINATION MODEL PLAN
Chapter 5
    A national contract for lamp recovery and recycling has been tied to the upgrade program; lamps removed
during the course of upgrades are packed and shipped to or picked up by the recycler. Under RCRA, many
fluorescent and other lamps must be handled as hazardous waste, either being recycled or disposed of in a
hazardous waste landfill. The relative costs of recycling versus hazardous waste landfill disposal vary signifi-
cantly by location, and type of lamp (e.g., fluorescent tubes vs. high intensity discharge lamps). In both cases,
end-of-life treatment is a small fraction of total lifecycle costs, which are dominated (90% on average) by
energy use.

    Detailed economic studies have been performed by other parties on lighting upgrade projects in general,
                 s
notably by EPA’ Green Lights program; Green Lights provides lighting project assessment tools to evaluate
upgrade costs and expected return. EPA figures indicate that incremental costs incurred by lamp recycling
programs make relatively little difference in the lifetime savings realized from reduced energy use in upgrade
projects. (That is, the additional cost of recycling is small compared to avoided costs of energy resulting from
installation of higher-efficiency lighting.) This reasoning does not apply, of course, to ongoing maintenance,
which involves piecemeal replacement of burned-out lamps with identical new ones. Kaiser Permanente’           s
efforts to integrate ongoing maintenance replacements into its lamp recycling program does add a small incre-
ment to total lifecycle costs.

       1       It is possible to view both digital and mercury thermometers as having an incremental cost of use — for digital
              thermometers, this is the cost of the sterile, disposable cover. For mercury thermometers, this incremental cost is:
               (unit purchase cost + unit disposal cost)/ (expected number of uses).. This omits discounting and spill, compliance, and
               treatment costs.

  This list is intended to demonstrate the wide variety of laboratory chemicals that may contain mercury. It
  was derived from examining the Massachusetts Water Resources Authority Mercury Source Identifica-
  tion Program Database (See Chapter 5, Mercury Reduction Case Studies, and Appendix I, Educational
  Resources for a Mercury Pollution Prevention Program).

  Some of the chemicals may contain added mercury, and others may contain mercury as a contaminant in
  a feedstock. If the mercury is a contaminant, its presence or absence may vary from lot to lot. In the
  case of kits, it is necessary to consider separately each of the reagents that make up the kit.

  This list should not be assumed to be complete. Request that vendors disclose mercury concentration on
  a Certificate of Analysis for all chemicals ordered. See Appendix G for a sample letter requesting mercury
  information and sample Certificate of Analysis.

              Benefits of a Mercury Pollution Prevention Program in Your Hospital (Handouts)

     Addresses Human Health Concerns About Mercury in the Environment
     • Hospital medical equipment contains a much larger amount of mercury than home medical
        equipment, and thus presents a larger potential hazard. For example, while a home fever
        thermometer contains about 1.59 grams of mercury, a desk-mounted sphygmomanometer
        contains about 83.7 grams of mercury.
     • There are human health impacts due to eating mercury-contaminated fish and fish
        consumption advisories due to mercury
     • Worker and patient exposure to mercury from broken thermometers and other mercury-containing
        devices could be avoided by using mercury-free equipment
     • Health professionals practice preventive medicine for public health.

     Reduces Discharge of Mercury into the Environment
     • Discharge to the air from incineration, and deposition of the airborne mercury back to the ground or
        water
     • Discharge of mercury in wastewater to sewage treatment plants, and from there to:
        • A waterway, or
        • The air if sludge is incinerated, or
        • The soil if sludge is land spread.

     Helps to Avoid the Need for Future Environmental Regulations
     • As a result of the Federal Great Lakes Water Quality Guidance (also referred to as the Great
        Lakes Initiative), several states have adopted stricter water quality standards for mercury .
     • The hospital may not be able to meet stricter state standards for discharge to the sewage
        treatment plant without action.
     • Implementing best management practices now can help to avoid the need for increased
        regulations in the future.

     Produces Hospital Operations Efficiencies
     • Mercury Pollution Prevention avoids:
        • Disruption of services due to spills
        • High disposal costs of mercury
        • Need to train staff for handling mercury
        • Costs of end-of-pipe treatment that may be needed to meet upcoming regulations
     • Mercury alternatives are becoming more readily available and in many cases are cheaper.

     Demonstrates Leadership
     • Your hospital is a leader in the local medical community.

     Examples of What Some Hospitals Are Doing
     • See tables

                                     Wastewater Sampling and Analysis

Measurement of success is vital to determining the effectiveness of a pollution prevention program. In order to
measure success a point of reference needs to be established. This is called a baseline (or starting) point. One
of the ways a baseline can be measured is through wastewater monitoring. Be sure to consider all the wastewa-
ter lines leaving hospital property.

Both analytical concentration of mercury and the volumes of flow need to be measured. This data should be
combined to result in a mass loading of mercury to the sewage treatment facility or receiving stream. All sewage
treatment facilities measure discharges the same way. By measuring with the same units as these facilities,
apples-to-apples can be compared. Sewage treatment plants in the Great Lakes basin measure mercury in the
parts-per-trillion (ppt) range. But upstream, at the source of the mercury, parts-per-billion (ppb) testing may be
sensitive enough. See below for examples of calculations based on these two concentration ranges.

Mass loading calculation:

 Mercury in ppb x Flow in mgd* x 8.34** = Mass mercury loading in lbs/day
    1,000

 Mercury in ppt x Flow in mgd* x 8.34** = Mass mercury loading in lbs/day
  1,000,000

This mass loading calculation should be used to calculate your baseline point, to monitor progress, and to help
measure program success. This calculation should be done over a period of time. By repeating the flow and
analyses, a more accurate status can be determined. Contact a local wastewater testing laboratory to identify
options for sample collection and analysis. Clean sampling techniques, as defined by the U.S. Environmental
Protection Agency, may be required for very low detection limits. You can monitor your progress by collecting and
analyzing samples one to four times per year.

* mgd: million gallons per day
** 8.34 is a set of conversion factors consolidated to one number so that units will work out.
ppb is equivalent to micrograms per liter (µg/L).
ppt is equivalent to nanograms per liter (ng/L).

  Subject: Certificate of Analysis

  Dear Ms. Smith:

  As you are aware, mercury is ever increasingly becoming a concern as an environmental pollutant. Mercury released
  from air and water sources is transformed into methylmercury in lakes or rivers. The methylmercury bioaccumulates
  in the aquatic food chain making consumption of fish hazardous to those organisms high on the food chain. As a
  result, regulations on the discharge of mercury to the solid and wastewater stream are becoming increasingly strin-
  gent.

  Because of this knowledge, and our concern for the environment, our institution has instituted a mercury reduction
  policy. This policy requires the elimination or minimization of mercury in all our purchases. Low level concentrations
  of mercury in products (less than 10,000 ppm or one percent) are not required to be listed on Material Safety Data
  Sheets. The contribution from the sum of these low concentration sources accounts for a large fraction of the mercury
  in the wastewater stream. In order for our purchasing department to be able to make an informed choice on mercury
  concentration within the products that it buys, we are requesting that all vendors supply us with a certificate of analysis
  and/or a notarized affidavit which describes product mercury concentration and the detection method used in the
  analysis. This information will be used along with other criteria in the selection process of our vendors.

  Please submit the aforementioned information on all products that you intend to supply our institution. Thank you for
  your understanding and assistance in this matter.

  Sincerely




  Jane Doe

                                                         This booklet has been developed to enlist your
                                                         help in a region-wide effort to manage amalgam
                                                         waste so as to protect the environment from
                                                         mercury. The amalgam management practices
                                                         described in this booklet were developed during
                                                         the past few years by dentists at the University
                                                                       s

                                                         Eastman Dental Center in Rochester, New York,
                                                         and by dentists in Minnesota, in cooperation
                                                         with the Western Lake Superior Sanitary District.
                                                         The methods have been shown to be effective in
                                                         keeping mercury from amalgam out of the
                                                         environment.
        Share this booklet with your staff. When new employees join your staff, make sure that they read
           this booklet also. You and your staff together can evaluate your current practices and, where
           appropriate, adopt new practices to protect the environment from the discharge of mercury
           from dental amalgam.



        There are many ways that mercury from dental amalgam can get into the environment:
        • Amalgam particles that are rinsed down drains or that escape poorly maintained chair-side
           traps and vacuum pump filters travel through the sewer system to the wastewater treatment
           plant. From there mercury from the amalgam may enter the environment in one of three
           ways: (1) It may be released directly to a waterway; (2) It may be released to the air if the
           treatment plant sludge is incinerated and then re-deposited to the ground or a waterway; (3) It
           may be released to soil if treatment plant sludge is land spread.
        • If a dental practice is connected to a septic system, amalgam particles become part of the
           sludge in the septic tank, which is eventually pumped out and transported to a wastewater
           treatment plant or land spread. Any mercury from the amalgam that becomes soluble will
           end up in groundwater.
        • Placing an item that contains amalgam particles in a red bag allows mercury from the amal-
           gam to be released into the air if the medical waste is incinerated. The volatilized mercury is
           then re-deposited to the ground or a waterway.
        • If items that contain amalgam particles are discarded with the ordinary trash, there is the
           potential for mercury from the amalgam to leach into groundwater when the trash is placed in
           a landfill not designed to handle hazardous waste.
        • In an older dental clinic, pure bulk mercury from past practices may have settled in sink traps.
           The mercury is gradually released into wastewater for many years after the use of bulk mer-
           cury has been discontinued.



                                                                                                         1

     New federal regulations greatly reduce the amount of mercury that is allowed to be discharged
        from a municipal wastewater system or an incinerator. By implementing the best management
        practices described in this booklet, you can reduce the level of mercury in the environment and
        avoid the need for increased regulations in the years to come.




     Stock your amalgam materials in a good choice of capsule sizes, in order to better select the right
        amount of material for a particular restoration. This will minimize waste.

     Dental scrap amalgam should be collected and stored in two designated, tightly closed, widemouth
        plastic containers. One container should be labeled CONTACT AMALGAM (amalgam that has
                            s
        been in the patient’ mouth). The other should be labeled NONCONTACT AMALGAM. Neither
        the New York State Department of Health nor the Occupational Safety and Health Administra-
        tion (OSHA) requires that contact amalgam be discarded in a medical waste red bag.

     Most recyclers prefer that contact amalgam be transported for recycling in a disinfectant. The
        liquid is visual evidence that the contact amalgam has been disinfected. Noncontact amalgam
        in a tightly sealed container can be stored and transported dry.




     Collect and store the entire contents of broken or unusable capsules with your noncontact scrap
         amalgam. If empty dental amalgam capsules contain no visible amalgam materials, they may
         be placed in the trash.

     If there is a spill of mercury from a capsule, contain it and clean it up immediately. Keep mercury
          clean-up materials on hand, and train a staff member in proper spill clean-up. Inexpensive
          mercury clean-up materials are available from science and safety equipment suppliers. (Some
          suppliers are listed on page 8.)




     When the fine particles of amalgam come in contact with cleaning agents and chemicals in the
        suction system and sewers, the mercury may be released. Large particles of amalgam can be
        prevented from entering the sewer system by the use of chair-side traps and vacuum pump
        filters. Material captured in the traps and filters can be sent to a recycler. Calculations based
        on data in scientific literature indicate that, when used properly, chair-side traps and vacuum
        pump filters can capture about 70% of the amalgam that enters the vacuum system.




                                                                                                             2

         Never rinse scrap amalgam down the drain.
         Never place scrap amalgam in the medical waste red bag.
         Never place scrap amalgam in the trash.

       Recommended techniques for collecting amalgam from the chair-side traps are as follows:

       1. Change or clean chair-side amalgam traps often. The frequency may vary from daily to weekly
          depending on how often the chair is used for amalgam placement or removal and the effective-
          ness of the suction.

       2. Flush the vacuum system with disinfecting line solution before changing the
          chair-side trap. The best method is to flush the line at the end of the day,
          and then change the trap the first thing the next morning.

       3. Use universal precautions (gloves, glasses and mask) when handling the
          chair-side trap. Choose utility gloves intended for cleaning and handling
          wastes for this procedure.

       4. Do not place gloves, plastic bags or paper towels into the recycling con-
          tainer. These add to the volume of the waste created and cause problems
          in the recycling equipment.

       5. Remove all visible amalgam by tapping the contents into the container labeled CONTACT
          AMALGAM. Close the cover tightly. If the trap is visually clean, it can be put in the trash. These
          visually clean traps have been determined to be nonhazardous.* (A heavily contaminated trap
          should always be recycled. It should be placed in the contact amalgam container.)

       Vacuum pump filters are usually located upstream of the central vacuum pump. Recommended
          techniques for recycling the vacuum pump filters are as follows:

       1. Replace or dispose of these filters regularly as recommended by the
          equipment manufacturer.

       2. Use universal precautions.

       3. Remove the filter and decant, over a tray, as much liquid as possible
          without losing visible amalgam.

       4. Put the lid on the filter and place the filter in the box in which it was
          originally shipped. When the box is full, the filters should be recycled.

    After your office adopts its new amalgam management practices, it may be a good time to replace
        sink traps. Mercury from past practices often settles at low points such as sink traps and
        sumps. The slow dissolution of the mercury in a sink trap or sump can release mercury into the
        wastewater for years after past disposal practices have been corrected. Whenever plumbing
        parts are moved or cleaned, caution should be taken to avoid spilling the contents in case
        amalgam or mercury are present. Pour and brush out the sludge and handle it as you would
        handle contact amalgam. The plumbing parts can be put back in place or discarded in the
        trash.



    If you have an older dental office, alert renovators to the possibility of mercury contamination in
         carpets, in floor cracks, behind moldings and other areas where bulk mercury may have been
         used, or where amalgam capsules may have been spilled. Call your county health department,
         district office of the New York State Department of Health, or regional office of the New York
         State Department of Environmental Conservation if you have questions about disposal of
         renovation debris. (See page 7 for telephone numbers.)


    Systems are available to treat wastewater contaminated with amalgam particles that are too fine to
        be caught in traps or filters. Most systems employ centrifugation or enhance sedimentation of
        particles. Some can also capture mercury that is in solution. Some of the new equipment can
        remove more than 99% of the mercury in the wastewater. It is used in some European coun-
        tries, where removal rates of at least 95% are required. The systems are being evaluated in
        dental offices in the U.S. Equipment can be purchased or leased. These systems are expensive
        now, but may become cheaper in the future. Contact 716-292-3935 for further information.


    In 1994 the American Dental Association recommended that dentists eliminate the use of bulk
        dental mercury by switching to precapsulated amalgam alloy in their practices. Measurement of
        the ratio of liquid mercury to amalgam powder is much more exact with the precapsulated
        technique. There is also less possibility of leakage during trituration. The use of precapsulated
        amalgam alloy eliminates mercury dispensers and containers as sources of mercury vapor, and
        eliminates the possibility of spilling a large quantity of mercury.
    Recycle bulk mercury. If there is a spill of a large amount of bulk mercury before it is eliminated
        from your office, call your county health department or district office of the New York State
        Department of Health for instructions about cleaning it up. (See page 7 for telephone numbers.)

       There are four options for recycling the amalgam from your dental office.

       1. Amalgam containers only: Mail via U.S. Mail to the Monroe County Household Hazardous Waste
          Facility in Rochester. It has authorization to collect noncontact amalgam and contact amalgam
          by mail from other counties, as well as from Monroe County. Make arrangements with the
          Monroe County Household Hazardous Waste Facility at 716-760-7600 to receive detailed
          instructions for amalgam recycling. Packaging materials will be provided for your office as long
          as supplies last.

       2. Amalgam containers, vacuum pump filters and bulk mercury: Deliver directly to the Monroe
          County Household Hazardous Waste Facility in Rochester. Materials can be dropped off
          without an appointment in the Industrial Waste Office foyer of Building 15 at 444 East
          Henrietta Road, in Rochester. The foyer is open between 7:00 a.m. and 4:30 p.m. Monday
          through Friday. The Facility has authorization to accept deliveries of these materials from other
          counties, as well as from Monroe County. Call 716-760-7600 for directions to the Facility and
          other information.

       3. Amalgam containers and vacuum pump filters: Ask your infectious or hazardous waste hauler if
          delivery of amalgam containers and vacuum pump filters to a mercury recycler or the Monroe
          County Household Hazardous Waste Facility can be arranged.

       4. Amalgam containers, vacuum pump filters and bulk mercury: Work directly with an amalgam
          recycling company. There are many questions you will need to ask when choosing a recycler:
          • What can I recycle?
               • Contact amalgam
               • Noncontact amalgam
               • Chair-side traps
               • Vacuum pump filters
               • Bulk mercury
          • What are the costs or profits
              for recycling each of the
              above?
          • What are the instructions for
              disinfection of contact
              amalgam?
          • What are the packaging
              requirements for contact
              amalgam, noncontact amal-
              gam chair-side traps, vacuum
              pump filters and bulk mercury?                   (See page 6 for a partial list of recyclers.)

                                       Mercury Waste Recyclers
    The U.S. mercury waste recyclers listed below are full service recyclers. In general, they will
    accept the full range of mercury waste from a hospital: thermometers, gastrointestinal tubes,
    laboratory chemicals, batteries, lamps, relays, switches, thermostats, manometers, metallic
    mercury, and mercury-contaminated material. They also accept dental amalgam from hospitals
    that have a dental clinic. See the following pages for a list of fluorescent lamp recyclers.

    Specific services vary from company to company. Each user is responsible for verifying vendor
    information. The list below does not imply an endorsement of any company, and it is not
    intended to be all-inclusive, but is provided for informational purposes only. In addition to
    contacting the companies listed, you can ask your current hazardous waste hauler to put you in
    contact with a mercury recycler.

    The following lists of recylers have been verified as of July 1999. These lists will be
    updated periodically.

                                       Infrastructure Control Measures

           (Information taken from the final version of the Mercury Management Guidebook,
      prepared by the Massachusetts Water Resource Authority (MWRA) / Medical Academic and
    Scientific Community Organization Inc. (MASCO) Mercury Work Group, Boston, MA. The full text
              of the Guidebook can be found at the World Wide Web address listed below.)

    Please note: This Appendix cites many regulations which only apply to the state of Massachu-
    setts. While the regulatory information is state-specific, this excerpt on infrastructure control is
    general enough to be of use to any facility concerned with mercury and organic build-up.)

    The MWRA/MASCO Mercury Work Group, public-private partnership of the Massachusetts Water
    Resources Authority (MWRA) and sewer dischargers (including hospitals, universities, and other
    industries), was established in 1994 to study and implement ways to reduce mercury discharges
    to the MWRA sewerage system. One organization, the Medical Academic and Scientific Commu-
    nity Organization Inc. (MASCO) that represents many Boston hospitals, has worked from the
    beginning of this effort to help identify the sources and methods of removing mercury from hos-
    pital waste streams.

    One area studied by the MWRA/MASCO Mercury Work Group was the waste piping infrastructure
    of a facility because elemental mercury waste deposits and mercury-contaminated bacteriologi-
    cal growth (biomass) were identified as possibly significant contributors to chronic mercury con-
    tamination in wastewater discharges. Some of the accumulated mercury could be biologically
    converted to methyl mercury which is both soluble and highly toxic. In addition, research by
    several hospital institutions found that the biomass within their “ Special Waste” plumbing sys-
    tems would readily absorb and accumulate mercury, with concentrations reaching as high as
    1,000 parts per billion. Fragments of biomass were seen to periodically break off and carry the
    absorbed, concentrated mercury to the sewer discharge. Because of these concerns, the Work
    Group developed in its Mercury Management Guidebook a section called “       Infrastructure Control
    Measures”to assist facilities that experience mercury-contaminated biomass within their waste
    piping infrastructure.

    For additional information on source reduction, infrastructure maintenance and end
    of pipe treatment modalities, please refer to the MASCO website at www.MASCO.org/
    mercury.

Appendices

   As outlined in Section 2.5 of this Guidebook, infrastructure control measures may include the
   following steps:
                          - source reduction
                          - source segregation, waste piping modifications
                          - waste trap sampling, cleaning, or replacement
                          - waste piping replacement or cleaning (power washing)
                          - wastewater collection for offsite disposal
                          - wastewater pretreatment (possibly consisting of equalization, solids
                            sedimentation, multistage filtration or other process steps)

   While these steps are listed in a possible chronological order, the actual number and order of
   steps could be different depending upon the facility and its Mercury Management Plan. Occasion-
   ally, earlier steps may be repeated before a later step is undertaken.

   Infrastructure control measures have been developed and undertaken at several facilities in the
   MWRA sewer service area because elemental mercury waste deposits and mercury accumula-
   tions in biomass growth from past discharge practices were identified as significant contributors
   to chronic mercury contamination of the wastewater discharges. The accumulation of mercury
   within waste piping systems containing biomass growth contributes to the complexity of wastewa-
   ter mercury management at a facility. In addition, because various biological nutrients may be
   contained in “ Special Waste”(defined below), biomass growth can be promoted in facilities that
   discharge such waste into the building waste piping infrastructure.

   The three appendices that follow are focused on mercury and biomass removal from piping sys-
   tems that carry Special Waste. However, the procedures discussed in these appendices can be
   followed by any facility where discharge of mercury-containing materials to waste piping systems
   has been confirmed or is suspected. The appendices are entitled Special Waste Piping Design
   (Appendix B-1), Special Waste Trap Cleaning/Replacement (Appendix B-2), and Special Waste
   Piping Power Washing (Appendix B-3).

   Before any of the guidelines and procedures presented in these three appendices are consid-
   ered, however, a facility should take all steps needed to prevent any elemental mercury or
   mercury-containing compounds from being disposed to the Special Waste drains of the facility.
   Continued disposal of any amount of mercury to the drains may mean that the waste trap and
   piping cleaning procedures would be totally ineffective or effective only for a short period. Then,
   the waste trap and piping cleaning procedures might have to be repeated to reduce effluent
   mercury concentrations.

  In addition, because of a lack of consistent analytical data developed before and after power
  washing of waste piping systems at several facilities, the MWRA is currently developing a policy
  concerning power washing of Special Waste systems. Specifically, the MWRA is concerned that:

           1) Power washing may be improperly considered by some facilities as a substitute for
          comprehensive mercury management that would include source reduction (including
          purchasing and inventory controls), source segregation (including training and
          supervision of waste disposal practices), and/or pretreatment.
          2) Power washing may lead to greater mercury violations for an indefinite period as
          small particles of loosened mercury-contaminated biomass are discharged with normal
           wastewater flows for several days or weeks after the power washing procedure.

  Refer to Appendix B-3 for details on the current state of MWRA power washing requirements.

  To introduce and clarify the following three appendices, Massachusetts Special Waste is defined
  below and the concepts of biomass growth and mercury bioaccumulation and bioconcentration
  are discussed.

  Special Waste

  According to the Massachusetts State Plumbing Code (248 CMR 2.13) “          Special Waste”includes,
  but is not limited to, chemicals, nuclear, radioactive, acids, alkalis, perchloric solvents, organisms
  containing recombinant DNA molecules, and other similar non-domestic wastes from various
  laboratories and industrial activities. These types of wastes are potentially detrimental to a public
  sewerage system and often do not comply with discharge limitations established by a local Pub-
  licly Owned Treatment Works (POTW) such as the MWRA.

  All Special Waste must be conveyed within facilities in a separate, dedicated waste and vent
  piping system. The Code covers piping design, types of waste neutralization systems, testing
  requirements, and inspection requirements for Special Waste piping systems. Allowed materials
  and installation methods are also specified. The Code does not specify the manner by which
  Special Waste piping systems are to be used after installation or what specific chemicals may be
  disposed into the system on a daily basis. On the other hand, the Code does prohibit the introduc-
  tion of solvent-bearing waste (248 CMR 2.13 (8)(e)) and requires the facility owner to submit a
  notarized letter stating what chemicals will be discharged into the Special Waste system (248
  CMR 2.13 (4)). The letter will be part of the basis of the design of the system by a Registered
  Professional Engineer. In addition, the Code states that wastewater treatment systems shall be
  part of the Engineers design when needed for compliance with regulatory limits (248 CMR 2.13
  (10)).




L-3                     MERCURY WASTE VIRTUAL ELIMINATION MODEL PLAN
Appendices
   All proposed Special Waste piping and pretreatment system installations, modifications, revisions
   and additions must be detailed in engineering drawings and specifications and certified by the
   Engineer. The drawings and specifications must be submitted to the local Plumbing Inspector for
   review and approval before construction. The approved documents are then submitted to the
   responsible jurisdictional authority (e.g., the MWRA or the MA-DEP) with the proper permitting
   documents and supporting engineering design data for final approval before the Special Wastes
   can be discharged to the sewerage system.

   Biomass Formation and Mercury Bioaccumulation and Bioconcentration

   Bacterial biomass growth in Special Waste piping systems can be promoted by the presence of
   organic matter such as blood products, urea, soaps, chemical reagents, and infectious wastes
   discharged into the piping system. The combination of organic matter, possibly elevated tempera-
   tures, and high humidity provides a good environment for biomass growth on the interior surfaces
   of the waste piping. The organic matter often contains methyl and dimethyl groups that can be
   combined by certain bacteria with inorganic mercury in the wastewater to create very toxic or-
   ganic forms of mercury (e.g., methyl mercury and dimethyl mercury). In addition, the mercury
   accumulates in the bacterial biomass and concentrates to significant levels. Because of the
   phenomenon of “  bioconcentration,” bacterial biomass mercury concentrations 1,000 times greater
   than that found in the wastewater have been reported.

   Within a flowing pipe, the biomass growth occurs principally below the liquid level with lesser
   amounts above. Within a trap at a sink or elsewhere, the growth can be more pronounced be-
                                                   incubator”with effectively no oxidation or dehy-
   cause the contained liquid creates a continuous “
   dration of the bacteria. A hardened skeleton of carbon, oxidized soap products containing ele-
   ments such as calcium and potassium, and dried blood products can be formed that strongly
   adheres to the piping surface.

   Figures B-1 and B-2 illustrate the mercury bioaccumulation and bioconcentration process in Spe-
   cial Waste traps and piping, respectively. A numeric key for the figures appears in Figure B-3 along
   with a general description of the bioaccumulation/bioconcentration process.

   When wastewater flows through the Special Waste piping system, “  slugs”of mercury-laden biom-
   ass may be carried into the wastewater stream when pieces of the accumulated growth are
   dislodged from the piping wall. Therefore, large amounts of bacterial biomass growth within the
   waste piping can lead to instances of high mercury concentrations in discharged wastewater. To
   move toward compliance with mercury discharge limits, therefore, this phenomenon may have to
   be addressed in facilities that have mercury-laden biomass growth. The following guidelines and
   procedures may help some facilities address the issue properly.

Appendices

  It should be noted that bacterial biomass formation can also occur within wastewater neutraliza-
  tion tanks. This formation can increase the potential for further mercury bioaccumulation/
  bioconcentration and wastewater contamination. According to the Plumbing Code,6 limestone
  chips are often used in sumps or tanks (i.e., chip tanks) for neutralization of Special Wastes
  containing dilute acids and alkalis. Chip tanks should not be used in facilities discharging signifi-
  cant quantities of organic matter, however, since bacterial biomass growth will tend to coat the
  limestone chips, rendering them useless for neutralization. It is recommended, therefore, that
  facilities check the condition and efficacy of any chip tanks and replace them with active (adjust-
  able) neutralization systems as appropriate. For additional information, refer to Section 2.5 of
  this Guidebook.

   1 • Liquid wastes enter the Special Waste piping system carrying organic liquid wastes, bacteria, and
       mercury wastes such as elemental mercury (Hg) and mercury salts (represented by HgCl2).

   2 • Elemental mercury and mercury salts are slowly metabolized by certain bacteria. Chlorides are
       oxidized to chlorates and mercuric ions (Hg+2) are released.

   3 • Elemental mercury is partly converted to mercuric ions (Hg+2).

   4 • Mercuric ions (Hg+2) combine with methyl ions (CH3-1) with bacteria acting as biological catalytic
       agents.

   5 • Toxic methyl mercury ions (CH3Hg+) and dimethyl mercury ( (CH 3) 2Hg ) are formed.

   6 • Methyl mercury ions (CH3Hg+) are absorbed and bioaccumulated/ bioconcentrated in the organic
       biomass growing on the Special Waste pipe wall.

   7 • Dimethyl mercury ( (CH3)2Hg ) molecules are absorbed and bioaccumulated/ bioconcentrated in
       the organic biomass growing on the Special Waste pipe wall.

   8 • Some molecules of dimethyl mercury ( (CH3)2Hg ) take a vapor form.

   9 • Some molecules of dimethyl mercury ( (CH3)2Hg ) vapor are absorbed and bio-accumulated in the
       organic biomass growing on the Special Waste pipe wall.

   10• Some molecules of dimethyl mercury ( (CH3)2Hg ) evaporate and are potentially released into the
       workplace atmosphere from liquid surfaces in traps of the Special Waste piping system.

                        SPECIAL WASTE PIPING DESIGN MODIFICATIONS

      Introduction

      This Appendix presents example design considerations for waste piping infrastructure. Modi-
      fications that may be needed before initiation of any cleaning or replacement activities in
      response to known mercury contamination.

      Facility Infrastructure Inspection

      The first step in dealing with known mercury contamination in the waste piping infrastructure
      of a facility is to conduct an audit of the existing piping systems. Drawings that reflect details
      of the actual waste piping, vent piping, and any associated pretreatment system installa-
      tions should be prepared. Special Waste diagrams are important tools and can show regu-
      lating authorities that the facility has knowledge and control of all Special Waste discharges.
      These diagrams should display all piping materials and sizes, traps, isolation valves, glass
      inspection ports or sections, and sampling/drain valves. The diagrams should also show any
      current areas lacking control or isolation of Special Waste discharges.

      Piping System Design and Modification

      After the piping system audit, the facility may determine that modifications are necessary to
      allow for isolation of waste streams, cleaning, sampling, testing, and monitoring. System
      designs or modifications should consider the following: the type of wastes being discharged
      and the piping material compatibility. Metal piping systems deserve special attention be-
      cause of the potential for mercury to form an amalgam with the metal. Cleaning of metal
      piping systems is not expected to reduce effluent mercury concentrations. The cleaning
      effort may actually cause an increase in effluent mercury concentrations. Thus, redesign
      and replacement of the systems using nonmetal materials should be strongly considered
      instead of attempts at cleaning.

      As outlined in Section 2.5 of this Guidebook, infrastructure control measures may include
      the following steps:

      -       the future uses of laboratory spaces (i.e., a chemical research laboratory
              that is to be changed to a blood testing laboratory).
      -       the need to isolate branch piping from waste and vent stacks to allow pipe
              cleaning (if needed and selected) without constricting waste flows from other
              areas or causing overflows to uncontaminated piping systems.
      -       the investigation of unidentified Special Waste sources and associated
              piping for bacterial
      -       biomass and mercury content before combining with previously identified
              Special Waste piping. Pending the results of investigation of these new sources,
              additional isolation valving and/or new dedicated risers discharging to the
              neutralization system may need to be installed.


L-9                     MERCURY WASTE VIRTUAL ELIMINATION MODEL PLAN
Appendices


    For trap cleaning/replacement and power washing procedures as discussed in Appendices B-2
    and B-3, respectively, any disinfecting or cleaning agents proposed for use must be reviewed in
    relation to possible interactions with the chemicals that may be contained in the waste piping
    system. The potential for incompatible reactions should be considered to ensure that trap clean-
    ing and power washing procedures will not create any unsafe conditions. Reactions that may
    cause fuming and gas evolution into the working environment, and into the piping system, must be
    avoided.

    Isolation Valves

    The facility may determine that isolation valves need to be installed to allow for trap cleaning/
    replacement, removal of noncompliant wastes, sampling of suspect branch piping, and control of
    potential cross-contamination. The location of isolation valves should consider accessibility and
    maintenance especially when co-fitted with a sampling port for testing.

    The location of valves should not cause an overflow of noncompliant wastes into another area
    where a spill may occur. As an example, a floor drain would overflow if too much liquid used for
    pipe cleaning was poured into a counter top sink at a higher elevation. Additionally, the need to
    provide isolation valves in the venting system must not be overlooked for the same reasons.

    Sampling Ports

    Sampling ports should be installed in strategic locations for the periodic collection of wastewater
    samples for monitoring purposes. Design of the sampling ports can follow that shown in Figure 2,
    Recommended Sampling Port for Special Wastes, of the Pretreatment Guidance Manual MWRA/
    MASCO Mercury Work Group, December 1997.

    A sampling port in an isolated branch of piping may not only act as a monitoring point but also as
    a drain leg for any disinfecting or cleaning agents used. The sampling port nozzle may be replaced
    with a full-size drain leg for transfer of suspected noncompliant cleaning wastes to containers for
    off-site disposal.

    Special Waste Risers

    Vertical Special Waste and vent piping risers may need to be isolated to allow for sequential
    disinfection, cleaning, and testing of portions of entire systems in the same manner as has been
    explained for horizontal runs of piping. During these periods, special consideration must be given
    to the isolation of vent piping to reduce the possibility of overflow of reagents back through the




             MERCURY WASTE VIRTUAL ELIMINATION MODEL PLAN                                                 L-10
Appendices
       piping system.

       Glass Inspection Ports

       Inspection ports or sections of clear borosilicate glass piping should be installed within the main
       horizontal runs of the Special Waste piping system fabricated of thermoplastic or other opaque
       piping materials so that flow conditions can be viewed and the bacterial biomass accumulation
       can be periodically observed. If any branch piping may contain undiluted caustic or hydrofluoric
       acid, however, the branch piping sections should be routed separately and connected down-
       stream of a glass fitting and should have its individual isolation valves and sampling port assem-
       blies.

       Discussion
       The above are examples of the various design considerations needed for modifications of Special
       Waste piping systems before cleaning or replacement activities are initiated. However, before
       modifying any portion of its waste piping infrastructure, a facility should determine if the system
       contains any metal piping or fitting materials that would require replacement and not cleaning.

       In addition, a thorough inspection of any traps and horizontal piping runs (including analyses of
       biomass samples) should be done to find if modification, cleaning, or replacement efforts should
       be done at all. If trap and biomass contaminations are found, the decision would then be made to
       pursue a specific combination of source reduction, source segregation, infrastructure modifica-
       tion, infrastructure replacement, infrastructure cleaning, and pretreatment as a solution to non-

     compliance with mercury sewer discharge limitations.

                                           APPENDIX B - 2
                             SPECIAL WASTE TRAP CLEANING/REPLACEMENT

     In Special Waste systems, trap accumulations of elemental mercury and of bacterial biomass
     growth contaminated with mercury has been found a significant source of chronic elevated mer-
     cury concentrations in wastewater discharges. The trap cleaning and replacement procedures
     outlined below have been found of significant value in reducing the levels of mercury in affected
     wastewater discharges.

     Trap Location / Identification

     Trap locations are determined by preparing a detailed inventory of all Special Waste sources.
     Trap identification can be accomplished as part of the facility piping system audit discussed in
     Appendix B-1. After all sources are identified, a facility Special Waste piping general arrangement
     drawing should be generated with all traps identified by unique numbers. A master inventory of all
     traps should be generated to record and track all trap cleaning or replacement events. Each trap
     should be tagged or labeled with its unique number, the cleaning or replacement date, and the
     name and signature of the person doing the cleaning/replacement. A Special Waste Trap Inven-
     tory Form such as shown in Figure B2-1 can be used to document the information and can
     include additional information such as the type and size of piping material.

     Removal of Elemental Mercury

     Elemental mercury is sometimes discharged into sinks and floor drains when mercury-containing
     equipment breaks. Some elemental mercury sources include mercury thermometers, thermo-
     stats, electric switches, and blood pressure manometers. When a sink or floor drain trap is
     removed for the first time, it may contain elemental mercury, identifiable as a pool of heavy silvery
     liquid separated from the trap wastewater.

     Elemental mercury removed from any traps should be collected and disposed as a mercury waste.

   Removal of Biomass

   Almost every trap will accumulate bacterial biomass, identified as a slimy brown film on the i nter-
   nal surface of the plumbing material. The bulk of this growth will occur on the bottom and wetted
   sections but some biomass will grow along the sides and top of the non-wetted section of the
   plumbing materials. This capillary action of growth is the most difficult to remove. Biomass growth
   on non-wetted surfaces can dry out. The dried out biomass develops a strong bond to the plumb-
   ing surfaces. In addition, any elemental mercury disposed into the drain can form an amalgam
   with metal plumbing. The amalgam is very difficult to remove from the trap. Accordingly, some
   facilities have chosen to replace contaminated traps rather than attempt to clean them.

   Trap Removal and Handling Precautions

   Where wastewater is elevated in temperature or where chemical reactions produce heat within a
   piping system, greater amounts of toxic fumes including dimethyl mercury may be formed in the
   accumulated biomass. Both elemental mercury and dimethyl mercury may exist in vapor form
   within the piping systems. Since negative pressures can sometimes exist in laboratory rooms,
   hazardous elemental or dimethyl mercury vapors can emanate from plumbing traps back into the
   rooms. Therefore, proper personnel protection should be practiced at all times. In addition, the
   traps should be of the deep seal type and should continually be filled to afford protection against
   possible vapor “ drawback.”

   Trap Cleaning or Replacement Procedures

   1. Identify traps for cleaning or replacement and discuss the trap removal procedure with the
   affected facility occupants. Explain to them that the procedure will interrupt their operations and
   estimate the duration of the interruption.
   2. Before any traps are removed, it is important to ask the occupants about the nature of their
   wastes, identifying all possible health and safety hazards. Before handling traps that are in areas
   that contain hazardous materials, all traps should be checked by the appropriate administrator
   for approval (i.e., if a radioactive isotope is being used in a room, have the Radiation Safety
   Department check out the trap to assure that it is safe for removal and handling).
   3. After facility occupants have been made aware of the trap cleaning/replacement program
   and after it is determined that it is safe to handle traps, actual trap removal, replacement, and
   cleaning can be started.
   4. It is important that personal protective equipment be worn at all times by any personnel doing
   trap handling. It is recommended that all these procedures be reviewed by an internal Health and
   Safety Officer.
   5. It is recommended that all materials found inside the traps be initially handled as mercury
   waste and then disposed of as mercury waste unless analyzed and found otherwise. See Appen-
   dix C for information on the proper disposal of mercury waste.
   6. If the removed trap is to be cleaned, either a rag or flexible brush can be used. A cleaning
   agent and some type of disinfectant may also be used to help ensure that complete removal of
   bacterial biomass and disinfection is accomplished. For metal traps, replacement is usually pre-




             MERCURY WASTE VIRTUAL ELIMINATION MODEL PLAN                                                 L-14
Appendices

       ferred because of the potential for mercury to form an amalgam with the metal.
        7. After traps are removed, cleaned or replaced, and reinstalled, a tag or label
       should be wired to the trap (or an existing tag should be updated) with the unique
       number of the trap, the date, and the responsible individuals’   initials.
        8. After trap removal, cleaning, or replacement is completed and the area is re-
       turned to its original condition, all access panels and other structural materials
       should be reinstalled. Before leaving the area, inform the occupants that the proce-
       dure has been completed.
       9. All trap cleanings or replacements should be logged on a Trap Inventory Form
       (See Figure B2-1 for an example inventory form).
       10. If it is known that any mercury-containing materials will remain in use, the asso-
       ciated wastes should be segregated and collected for offsite disposal. Otherwise, it
       will be necessary to inspect the affected cleaned traps for recurring contamination
       of the biomass growth. These inspections could serve as a check on actual disposal
       practices and could initially be done quarterly. Once a sufficient level of experience
       has been obtained, inspection frequencies can either be increased or decreased
       depending on the levels of contamination and the rates of returning biomass. The
       inspections should help determine the need for repetition of the entire procedure.
       11. It is highly recommended that spare traps and associated hardware be avail-
       able for each type and size of trap because corroded or otherwise unusable traps
       are often discovered during a cleaning/replacement program.

                              SPECIAL WASTE PIPING POWER WASHING

   Background

   In the past, Special Waste piping systems were sometimes used for the disposal of mercury and
   mercury-containing materials. Because of the phenomena of bioaccumulation and bioconcentration,
   the bacterial biomass within such Special Waste piping systems could contain concentrations of
   mercury in the part per million range. In some cases, the presence of such mercury-laden biom-
   ass was cited as the sole reason that mercury was detected in discharged wastewater at con-
   centrations exceeding the MWRA enforcement limit of 1.0 mg/L (ppb).

   A few facilities have used power washing of their Special Waste piping systems as a mercury
   control technique because of the scouring effect of power washing on accumulated mercury-laden
   biomass that effectively removes the biomass. Some of these users believe that, after all needed
   mercury source reduction has been carried out, power washing would be a lower cost final step in
   effluent mercury control than removal and replacement of the contaminated Special Waste pip-
   ing system.

   Special Waste piping power washing uses specialized pumping equipment to produce a high pres-
   sure/low volume stream of water. The water stream flows through a high pressure hose and a
   power nozzle to produce a 360 degree high velocity spray that can remove accumulated biomass
   and grease from the inside surfaces of the waste piping while flushing the resulting debris down
   the line.

   Status of MWRA Power Washing Requirements

   Currently, there are uncertainties in the ability of power washing to remove all biomass residues
   thereby possibly exposing new surfaces from which mercury can reach the wastewater. Also,
   there is some evidence that power washing may lead to new and possibly higher mercury viola-
   tions from the discharge of dislodged biomass particles for an indefinite period after power wash-
   ing is performed. Because of these concerns, the MWRA is currently formulating requirements
   for data collection during power washing. As part of this process, a facility must notify the MWRA
   of its intention to perform power washing and participate in a study of power washing effects
   according to specific conditions and protocols. The results of the study will be used to finalize a
   MWRA guidance on acceptable power washing procedures.

                               INFRASTRUCTURE POWER WASHING PROCEDURES

       Because of the phenomena of bioaccumulation and bioconcentration, the biomass within a
       Special Waste piping system (that has been used for disposal of mercury-containing materi-
       als) may contain concentrations of mercury in the part per million range. Power washing has
       been used as a mercury control technique for such systems because of its scouring effect on
       the accumulated mercury-contaminated biomass. Power washing has been identified as a
       possible lower cost method of biomass control compared to replacement of the facility’    s
       waste piping system. However, because of the issues outlined below, power washing of
       waste piping systems may not be effective at all facilities.

       Power washing uses special equipment that produces a high pressure/low volume stream of
       water. The water flows through a high pressure hose and a power nozzle to produce a high
       velocity spray that removes accumulated biomass and grease from the inside of waste con-
       veyance piping while flushing the resulting debris down the line. Results of a power washing
       effort are dependent upon accessibility to the entire waste piping system (i.e., through use of
       piping isolation valves, cleanouts, access ports, and drains). In addition, there are uncertain-
       ties in the ability of power washing to effectively remove all biomass residues thereby possi-
       bly exposing new surfaces from which mercury can reach the wastewater, and there is evi-
       dence that power washing may actually lead to new mercury violations from continued dis-
       charges of dislodged biomass particles.

       Because of these issues, the MWRA will require prior notice of intended power washing by
       permitted dischargers. The MWRA is considering additional requirements including approval
       of power washing protocols and collection and offsite disposal of the facility wastewater
       during and after power washing until sampling and analyses show that mercury concentra-
       tions in the discharge have returned to the same levels or lower that existed before the
       power wash procedure. A possible alternate approach would be removal of dislodged biom-
       ass particles from the discharge possibly by sedimentation or multistage filtration.

       The temporary or permanent particle removal system could be installed within the piping
       system or at the final discharge point. The particle removal system could be considered
       separately or as part of a mercury pretreatment system. The proposed installation of the
       particle removal system must be disclosed to the responsible POTW, however, since the
       POTW will likely consider the system to be a type of pretreatment system.

       Some facilities have considered power washing to be an effective method for reducing mer-
       cury concentrations in their sewer discharges. If mercury-containing materials continue to be
       disposed to the waste piping system, however, the power washing procedure will not be a
       permanent solution and will likely have to be repeated on a continuing basis. If a facility
       should choose to engage in power washing, the following discussion should be referred to for
       precautions, recommended techniques, and possible compliance issues.

                               Power Washing Precautions

     The following are some precautions that should be considered before starting power
     washing procedures:
     • Waste conveyance piping accessibility is essential for successful power washing.
        Considerable modifications to an existing system may be needed to achieve the
        needed accessibility.
     • Perhaps because of the potential for mercury to form an amalgam with other metals,
        power washing is not expected to be effective in waste piping systems constructed of
        metals (i.e., high silicon cast iron or stainless steel). If a metallic waste piping system
        were mercury-contaminated, total replacement of the system should be considered.
     • All substances contained within the waste conveyance piping should be taken as
                                                           s
        hazardous. Before power washing, the facility’ Health and Safety Officer should
        review the proposed power washing procedure to ensure that proper personal protec-
        tive equipment will be used.
     • Waste conveyance fittings and piping, especially with glass fittings, can be cracked or
        broken during power washing. Inspect the entire run before power washing, and
        identify any potential obstructions, so that if a fitting is broken, a replacement fitting
        can be immediately available for installation.
     • If the waste conveyance piping contains large amounts of biomass, dislodged pieces
        may collect and clog downstream conveyance piping sections. If such clogging occurs,
        there may be wastewater backups in the plumbing system causing flooding at lower
        elevation locations.
     • Dislodged biomass particles can appear in the sewer discharge for some period after
        power washing. To avoid compliance problems from the power washing procedure,
        collection and offsite disposal of the affected wastewater may be needed until testing
        shows no elevated mercury levels. Alternately, the dislodged biomass particles could
        be removed from the discharge by a temporary or permanent removal system within
        the piping system or at the final discharge point. The proposed installation of a
        particle removal system, however, must be disclosed to the POTW since it likely will be
        considered a pretreatment system.
     • Any proposed sanitizing or cleaning agents should be reviewed to prevent possible
        chemical interactions with waste constituents that may exist in the piping system. The
        potential for incompatible reactions should be considered to ensure that trap and pipe
        cleaning procedures will not create unsafe conditions. Reactions that may cause
        fuming and result in gas evolution into the working environment, as well as into the
        piping system, must be avoided.

    Power Washing Techniques

    The following techniques are easily monitored for effectiveness when performed on glass waste
    piping systems. The techniques may require some modification when applied to thermoplastic or
    other waste piping materials.

    1.   Power washing activities usually require a minimum of two people: one serving as the power
         wash operator; and the other as an observer of the nozzle and hose as it moves through the
         waste conveyance piping.
    2.   The operator begins feeding the 80 to 100 feet of hose with the power washing nozzle
         attached, while the observer, with a two-way radio in full communication with the operator,
         watches the hose and nozzle for potential obstructions and other problems. Typical obstruc-
         tions include: tees, reducers, p-traps, drum traps and valves.
    3.   Some facilities have determined that successful power washing occurs when cleaning op-
         erations begin at the collection or treatment tanks in the lower floors. The operator then
         works in the waste piping system toward the sources in a reverse flow direction. This tech-
         nique is preferred because the nozzle is designed with a reverse flow head configuration
                        pulls”the hose away from the power washer operator and toward the sources
         that literally “
         while flushing biomass and debris down the line and to the collection point. In addition, most
         plumbing fittings have smooth swings in the reverse direction and this seems to reduce
         obstruction interference.
    4.   Although reverse flow is preferred, the complexities of the piping infrastructure may require
         some experimentation. For immediate progress, select straight sections observed to con-
         tain biomass. In other locations, piping may have to be removed or modified to reach all
         areas of concern. Power washing on thermoplastic piping will require more experimentation
         and it may be necessary to remove piping sections to verify cleaning effectiveness. The
         installation of sight glasses may help to reduce the required amount of pipe removal.
    5.   At times, it may be difficult or impossible to feed the hose and nozzle in the preferred re-
         verse direction. An alternative method would then be to start at the sources (sink traps or
         floor drains) and work in the direction of flow. This technique, however, is less desirable
         because the nozzle head will not be directly flushing debris as it moves along the piping. It
         may be necessary, then, to apply additional water to aid the flushing process by turning on
         an adjacent sink tied into the same waste conveyance line.
    6.   Regardless of the direction that the power wash nozzle is fed into the system, a final wash
         and high volume rinse in the direction of flow may help to flush residual biomass particles
         from the system.

     Chemical Addition

     Bleach
     Some power washing units are designed for use with water only and do not allow for addition of
     chemical solutions. However, it is recommended that a bleach solution be added to the piping at
     the source, if possible, to accomplish disinfection of the piping system before the power washing
     and aid in the removal of biomass. The bleach or other disinfecting chemical should be analyzed
     before use to ensure that it is mercury free or of a “ low”mercury content. Unfortunately, some
     chemicals and reagents, including many disinfecting products that contain bleach, may contain
     measurable amounts of mercury.

     Other Cleaning Solutions
     The additions of surfactants, dispersants, caustics and/or wetting agents were investigated dur-
     ing the MWRA/MASCO Mercury Work Group Phase I effort. None of these chemicals were rec-
     ommended then because of health and safety considerations. In addition, such chemical addi-
     tions may be costly for waste piping systems at large facilities. However, some power washing
     companies may offer chemical addition services and facilities may find that chemical addition is
     quite feasible, safe, and effective.

     Power Washing Wastewater Disposal

     All power washing wastewater that contains removed biomass should be assumed to contain
     levels of mercury above the MWRA enforcement limit of 1.0 µg/L (ppb) and, therefore, should be
     collected for offsite disposal. The collection of the power wash wastewater is difficult, but since
     power washing will usually occur during non-operating hours, the piping systems can virtually be
     drained. Once normal flow has stopped, existing neutralization or treatment tanks can be emp-
     tied and used as power washing wastewater collection vessels. Additional temporary collection
     vessels may be needed.

     After power washing is completed or the treatment tanks get full, transfer all collected wastewa-
     ter into storage containers. Other collection and pumping methods can be used on a case-by-
     case basis. However accomplished, it is very important that this wastewater be collected and not
     discharged.

     In addition, dislodged biomass particles can sometimes appear in the sewer discharge for some
     period after power washing. To avoid compliance problems, collection and offsite disposal of the
     affected wastewater or removal of the biomass particles from the discharge may be needed. A
     temporary or permanent filtration system within the piping system or at the final discharge point
     should be considered. The proposed installation of a filtration system, however, must be dis-
     closed to the POTW since it will likely be considered a pretreatment system.

       All waste disposal activities should be approved by an Environmental, Health and
       Safety Officer or the person responsible for waste disposal. The MWRA prohibits the
       disposal of chemicals into the sewerage system except for aqueous solutions of
       nontoxic and nonhazardous chemicals. 7 In addition, the Massachusetts Depart-
       ment of Environmental Protection (MA-DEP) prohibits the improper disposal of haz-
       ardous wastes.8

     Broken Thermometers: (There is not enough mercury involved to present a hazard. If the
         following steps are taken, you do not need to respond with the mercury vacuum*. Never
         use a regular vacuum to clean up a mercury spill.)

     1.   Using two 3" x 5" cards push mercury into a pile.
     2.   Draw up into a syringe (no needle) and place in a sealed container or scoop into a specimen
          container or other sealable container.
     3.   Disposal:
          Non-patient area: Fill out a hazardous waste tag and call the
                             Hazardous Waste Management Unit for pick up.
          Patient area:      Label container (mercury) and place on cart to be returned to Sterile Supply.

     ___________________________________________________________________________________

     Broken Manometers:

     SMH patient area:    Call should be referred to SMH Housekeeping.
     Other area:          Contact an Industrial Hygienist for immediate clean-up.

     **Note: Any call which sounds unusual (i.e. spilled on patient, on carpet, in toilet, not a ther-
         mometer or manometer) should be referred to an Industrial Hygienist.

     It is important to respond as soon as possible (within 1 or 2 hours) to clean-up any spill.

     1.   Make sure everyone is removed from the room (patient(s), visitors, staff).
          Patient bed should not be removed from the room.

     2.   Gather equipment
          • Specialized mercury vacuum* and attachments (stored in the SMH Housekeeping Office-
            If locked, have one of the supervisors paged.)
          • The mercury vacuum is designed to clean up liquid mercury spills.
            Regular vacuum cleaners can volatilize the mercury and blow the mercury vapors
            into the air. An activated carbon filter in this vacuum will absorb and contain
            the mercury vapors.

               • Tool box. The following items should be in the tool box:
                 • Flashlight
                 • Screwdriver
                 • Putty knife
                 • Mercury holding jar
                 • Respirator (3M 9908 Dust/Mist Respirator)
                 • Yellow or pink wash basin (from clean utility room on unit)
                 • Heavy plastic bag

    3.   Before entering room put on protective equipment.
              • Respirator
              • Long sleeve shirt
              • Long pants
              • Disposable gloves
              • Remove all jewelry

    4.   Assess the extent of the spill. Upon entering the room use flashlight (hold angled at floor
         level, put head close to floor to see where mercury is located). Also check wall, bed frame
         and mattress. Do not walk in contaminated areas.

    If there is anything unusual about the spill (i.e. on carpet, in a toilet, on patient, etc.)
    a member of the Industrial Hygiene Unit should be consulted.

    5.   Set up mercury vacuum using the following steps:
         A. Place plastic dishpan under separator.
         B. Remove red cap off mercury separator and screw jar onto vacuum.
         C. Remove red end cap from hose.
         D. Place required attachment on hose.

    6.   Begin vacuuming at outer edges of spill and work towards center of spill (usually the wall under
         the manometer). Set up an organized approach (i.e. begin vacuuming one block and move
         slowly, in a row to assure that you cover the entire area). Draw vacuum hand-piece slowly
         towards yourself. Pay special attention to floor moldings. If molding is pulled away from the
         wall and you suspect that mercury may have gotten behind it, remove the molding using the
         putty knife and vacuum behind it.

    7.   Once the area under the manometer has been vacuumed, remove the manometer from the
         wall bracket by unscrewing the top holding screw. Place the manometer in the wash basin. If
         the glass tube is not broken on the front of the manometer and there is no visible mercury on
         the outside of the manometer, put the manometer inside the plastic bag. Seal the bag and
         place in wash basin. If the tube is broken, empty mercury into the wash basin to be vacuumed.
         Then put the manometer into plastic bag and seal.

     8.   Once all the mercury has been vacuumed, take the flashlight and check again for beads of
          mercury on the floor, wall and bed. Several attempts may be needed to vacuum all of the
          mercury from a spill.

     9.   Place wash basin under mercury separator and unscrew jar. Place red cap over bottom of
          mercury separator and place red end cap on hose. Any mercury that may have fallen on the
          paper should be dumped into the jar. Place lid on jar and return jar to tool box*.

          If water has been vacuumed, notify Environmental Health and Safety (EH&S) immediately so
          that the appropriate maintenance can be performed.

          Removal of the jar after each use will extend the life of the activated charcoal filter.

     10. Pick up all materials and leave room.

     11. Leave manometer (in sealed bag) in the soiled utility room. The unit secretary should be in-
         formed to call to have the manometer replaced.

     12. Post sign on the door to assure that the room remains browned out and no one enters until
         EH&S has checked the room.

     13. Notify EH&S that the spill has been cleaned up. If the spill occurs during the normal 8-5:30 day,
         call EH&S immediately after clean up is complete. Please give the secretary the room number
         and other important details. If the spill occurs after 5:30 or on a weekend, leave a message on
         phone mail giving the room number and any other details about the spill.

     14. EH&S will respond with the mercury vapor sniffer and a flashlight to assure adequate clean up.
         Mercury vapor levels should be insignificant (<0.02 mg/m3) at floor level.

     15. The patient(s) may be returned to the room after EH&S has approved the room for use.

     *Note:      If mercury and spill debris reach the fill line on the jar, a Hazardous Waste Tag must
                 be filled out. The tag should be completely filled out and attached to the jar. The
                 Hazardous Waste Management Unit should be called to pick up the mercury.
