Introduction
The discovery of a variety of pharmaceuticals in surface,
ground, and drinking waters around the country is raising concerns about the
potentially adverse environmental consequences of these contaminants. Minute
concentrations of chemicals known as endocrine disruptors, some of which are
pharmaceuticals, are having detrimental effects on aquatic species and possibly
on human health and development. The
consistent increase in the use of potent pharmaceuticals, driven by both drug
development and our aging population, is creating a corresponding increase
in the amount of pharmaceutical waste generated.
Pharmaceutical waste is not one single waste stream, but
many distinct waste streams that reflect the complexity and diversity of the
chemicals that comprise pharmaceuticals. Pharmaceutical waste is potentially
generated through a wide variety of activities in a health care facility, including
but not limited to intravenous (IV) preparation, general compounding, spills/breakage,
partially used vials, syringes, and IVs, discontinued, unused preparations,
unused unit dose repacks, patients' personal medications and outdated pharmaceuticals.
In hospitals, pharmaceutical waste is generally discarded
down the drain or landfilled, except chemotherapy agents, which are often sent
to a regulated medical waste incinerator. These practices were developed at
a time when knowledge was not available about the potential adverse effects
of introducing waste pharmaceuticals into the environment.
Proper pharmaceutical waste management is a highly complex
new frontier in environmental management for health care facilities. A hospital
pharmacy generally stocks between 2,000 and 4,000 different items, each of
which must be evaluated against state and federal hazardous waste regulations.
Pharmacists and nurses generally do not receive training on hazardous waste
management during their academic studies, and safety and environmental services
managers may not be familiar with the active ingredients and formulations of
pharmaceutical products.
Frequently used pharmaceuticals, such as epinephrine, warfarin,
and nine chemotherapeutic agents, are regulated as hazardous waste under the
Resource Conservation and Recovery Act (RCRA). Failure to comply with hazardous
waste regulations by improperly managing and disposing of such waste can result
in potentially serious violations and large penalties.
Practice Greenhealth recommends this
10-step approach to help you develop and implement a comprehensive pharmaceutical
hazardous waste management program one that combines regulatory compliance
and best management practices with waste minimization to safeguard human
health and the environment, while minimizing risk in a cost effective manner.

Navigating the Blueprint
The steps in this Blueprint do not necessarily have to be
taken consecutively. Some steps will occur in parallel and other steps will
probably be referenced throughout the development of your pharmaceutical waste
management program. The following summary of the 10-steps describes how each
step can be used to develop and implement your pharmaceutical waste management
program: Step 1 provides action items that you can begin
immediately.
Step 2 is an overview of how the federal Resource
Conservation and Recovery (RCRA) regulations apply to pharmaceutical
waste management.
Step 3 begins where the regulations leave
off providing guidance on how to manage non-regulated hazardous
pharmaceutical waste.
Step 4 walks you through the steps necessary
to perform a drug inventory review. This step can be very tedious
and time consuming.
Step 5 alerts you to waste minimization
opportunities.
Step 6 It will be helpful to become familiar
with the waste minimization opportunities before assessing your
current practices based on the guidance provided in Step 6 and
to reference them again after you have performed your department
reviews.
Step 7 Taking on the Communication/Labeling
Challenge, Step 7 is one of the most critical aspects of implementing
a pharmaceutical waste management program and possibly the most
challenging. Step 8 How you decide to communicate
pharmaceutical disposition information to the people handling
the waste will depend and be dependent upon which of the management
options presented in Step 8 you select and what you learn in
-
Step 9, Getting Ready for Implementation.
Step 10 When all the preparation from Steps
7-9 comes together you will be ready for Step 10, Launching the
Program. Next Steps follows Step 10 and provides recommendations
for future efforts to facilitate environmentally sound pharmaceutical
waste management in health care facilities.

Applying the Precautionary Principle
This Blueprint focuses primarily on three aspects of pharmaceutical
waste management:
(1) Management of regulated hazardous pharmaceutical waste;
(2) Management of non-regulated hazardous pharmaceutical waste applying best
management practices; and,
(3) Minimization of pharmaceutical waste
While your first priority has to be the proper management
of hazardous pharmaceutical waste, careful consideration should be given to
the management of all pharmaceutical waste. As research data accumulates on
the adverse impacts of waste pharmaceuticals on human health and the environment,
applying the Precautionary Principle becomes increasingly relevant:
“When an activity raises threats of harm to human
health or the environment, precautionary measures should be taken even if
some cause and effect relationships are not fully established scientifically.”
When in doubt, apply the Precautionary Principle.
The
Wingspread Consensus Statement on the Precautionary Principle can be accessed
at http://www.sehn.org/wing.html.

Applying the Precautionary Principal
Step One: Getting Started
Designing and implementing a successful pharmaceutical waste
management program is a highly interdisciplinary process. It begins by obtaining
support from senior management and establishing a committee of stakeholders
that will meet regularly to develop and implement the program. This committee
may be the current Environmental Health and Safety Committee but must include
at minimum the leaders of Pharmacy, Environmental Services, Safety, Nursing,
Education, and Infection Control. Additional members for consideration are
personnel from Facilities/Engineering, Administration, Laboratory and Purchasing/Materials
Management.
Given the complexity of implementation and the potential
budgetary impacts (e.g., purchase of pharmaceutical waste containers and potentially
increased disposal costs), the newly formed committee may find it valuable
to arrange a presentation to senior management explaining the opportunities,
challenges and financial implications of proper pharmaceutical waste management
without getting into program specific details.
No single department owns all the responsibility
and no single department can implement a pharmaceutical waste management
program alone. |

Step One
Step Two: Understanding the Regulations
Pharmaceutical waste management is especially challenging
given the complexity of the regulations that govern this activity and the multiple
regulatory agencies that oversee it. Step 2 focuses primarily on how the federal
RCRA regulations apply to hazardous pharmaceutical waste management. It is
divided into four major sections to provide a broad overview of the applicable
regulations and an awareness of the overlap between RCRA and other statutes.
- Defining Hazardous Waste Categories
- Grappling with Hazardous Waste Combination
- Distinguishing Between Trace and Hazardous Chemotherapy
Waste
- Understanding Hazardous Waste Management
It is important to note that the RCRA regulations
were written with industrial waste generation in mind, not for finished
pharmaceutical dosage forms such as tablets, capsules, and injectables.
C hecking with federal and state regulators on areas that are open to potentially
differing interpretations is highly recommended. This Blueprint offers
a conservative interpretation in those situations. A conservative approach
is always acceptable and offers greater environmental protection. |
USEPA Region 2 has been very aggressive in inspecting and
enforcing hazardous waste regulations at the 480 hospitals in New York, New
Jersey, Puerto Rico and the U.S. Virgin Islands. Fines have ranged from $40,000
to almost $280,000. USEPA Region 1 has also begun a health care initiative
and has notified 250 hospitals in New England of its intention to enforce hazardous
waste laws in health care facilities.
State regulations may be more stringent than federal regulations
and may vary by state. A number of states, including California, Washington,
and Minnesota, have implemented more stringent hazardous waste regulations
that impact pharmaceutical waste management. Check your state regulations to
make sure that you understand your state-specific requirements.
Next
Steps contains a recommendation for clarifying, reconsidering and expanding
the RCRA hazardous waste regulations.
There
are additional resources in Appendix A: Tools and Resources that will provide
you with a more complete understanding of RCRA and your organization's responsibilities.
Regulatory Bodies that Oversee Pharmaceutical
Waste Management
- Environmental Protection Agency (EPA)
- Department of Transportation (DOT)
- Drug Enforcement Administration (DEA)
- Occupational Safety and Health Administration (OSHA)
- State Environmental Agencies
- State Pharmacy Boards, and
- Local Publicly Owned Treatment Works (POTW)

1. Defining Hazardous Waste Categories
Hazardous wastes are divided into two categories: (1)
listed wastes, and (2) characteristic wastes. Listed wastes appear on one
of four lists of hazardous waste (F, K, P and U). Pharmaceuticals are found
on two of these lists, the P and U lists which both contain commercial chemical
products. Characteristic wastes are regulated because they exhibit certain
hazardous properties ignitability, corrosivity, reactivity and toxicity.
Wastes that are not listed
and do not exhibit a characteristic are considered solid waste. Solid
wastes should be discarded according to state and/or local regulations
including regulated medical waste requirements. There are situations
where a solid waste should be handled as a hazardous waste applying best
management practices.
Step
3: Considering Best Management Practices for Non-Regulated Pharmaceutical
Wastes provides recommendations for applying best management practices.
|
a. P- Listed Wastes (40 CFR Part 261.33(e))
Pharmaceuticals are chemicals first and therapeutic agents
second. P-listed wastes are commercial chemical products that are categorized
as acutely hazardous under RCRA.
One of the primary criteria for including a drug on the P-list
as acutely hazardous is an oral lethal dose of 50 mg/kg (LD50) or less. LD50
is the amount of a material, given all at once, which causes the death of 50%
of a group of test animals. Eight chemicals on the P-list are used as pharmaceuticals
(see Table 1).

agents are noted in italics)

1 Does not include epinephrine salts (see www.epa.gov/region1/healthcare/pdfs/EpiMemo_Final.pdf) |
In health care settings, waste epinephrine (Waste Code P042)
is by far the most common hazardous drug waste generated. It is used most often
in cardiac care units and during orthopedic and ophthalmic surgical procedures
but may be generated anywhere in the facility to treat cardiac arrest and allergic
reactions.
Identifying
Waste Pharmaceuticals
Some drugs have more than one trade name. The underlying chemical
name, not the trade name, is regulated under RCRA. To be sure you do
not miss a chemical due to using a trade name or generic name, use
the Chemical Abstracts Service registry numbers that can be obtained
from the Merck Index or other chemical references and compare them
to the CAS numbers in the Code of Federal Regulations.
- Phentermine is a good example of the use of the CAS number, since
it is listed in the 40 CFR 261.33 only as Benzeneethanamine, alpha,
alpha-dimethyl-. By looking up phentermine in the Merck Index, its
CAS number of 122-09-8 would tie to the chemical name in 40 CFR 261.33(e)
to P046.
- Trisenox® is the trade name for arsenic trioxide which is
regulated as P012.

Resources for further assistance.

i. Two Necessary Conditions (40
CFR Part 261.33)
When a drug waste containing a P-listed constituent of concern
is discarded or intended to be discarded, it must be managed as hazardous waste
if two conditions are satisfied: (1) the discarded drug waste contains a sole
active ingredient (54 FR 31335) that appears on the P list,
and (2) it has not been used for its intended purpose (54
FR 31336). To satisfy the definition of sole active ingredient ,
the listed chemical in the discarded drug must be the only ingredient that
performs the intended function of the formulation. Ingredients that serve ancillary
functions such as mobilizing or preserving the active ingredient are not considered
when determining the sole active ingredient. The phrase “has not
been used for its intended purpose” refers to drugs and their
associated containers or dispensing instruments that have not been given to
a patient and need to be discarded. The portion of an IV infusion that was
not given to a patient and needs to be discarded is an example of an item that
has not been used for its intended purpose.
In order to maintain consistent release rates, transdermal patches
contain a surplus of active molecule. A stable concentration gradient
is the mechanism used to maintain consistent release rates and constant
serum drug levels. Most transdermal patches contain 20 times the amount
of drug that will be absorbed during the time of application. Therefore,
after removal, most patches contain at least 95% of the total amount
of drug initially in the patch.
Nicotine is a P-listed constituent of concern (P081). Do worn nicotine
patches need to be managed as RCRA hazardous waste? Nicotine is the
sole active ingredient. So, the answer differs depending on whether
you decide to evaluate the patch or the nicotine remaining in the patch
to determine if the drug has been “used for its intended purpose.” EPA
has not provided any specific guidance on how to manage worn dermal
patches.
|
ii. Empty Containers of P-Listed Wastes (40 CFR Part
261.7(b)(3))
A container that has held a P-listed waste is not considered “RCRA
empty” unless it has been:
(1) Triple rinsed, and
(2) The rinsate is managed as hazardous waste.
Since triple rinsing is not practical in health care settings,
all vials, IVs, and other containers that have held a P-listed drug must be
managed as hazardous waste, regardless of whether or not all of the contents
have been removed.
Tablets and Capsules Containing P-Listed Constituents of Concern
Are you managing the following as hazardous waste?
The Minnesota Pollution Control Agency does not consider
the “soufflé cups” used to deliver tablets and capsules containing
P-listed constituents of concern to be containers. Therefore, in
Minnesota these cups do not have to be managed as hazardous waste
unless they are overtly contaminated with a P-listed residue.
Check with your state regulatory agency for guidance
on their interpretation or apply a conservative approach and discard
all containers of P-listed waste as hazardous waste.
|
iii. Dilute Concentrations of P-Listed Waste
There are no concentration limits or dilution exclusions
for P-listed hazardous wastes. If saline or another solvent is added to a P-listed
chemical, additional P-listed hazardous waste is generated.
iv. Epinephrine Syringe Interpretation
Excess and residue epinephrine in a syringe after the proper
dose has been administered to a patient is the single pharmaceutical exception
to the definition of the phrase has not been used for its intended purpose. This
exception is based on a December 1994 EPA Hotline interpretation. After
the proper dose has been injected, EPA considers residues remaining in a syringe
to have been used for their intended purpose. Therefore, the syringe containing
residue epinephrine is not a P042 hazardous waste and can be discarded as Regulated
Medical Waste in a sharps container.
In the interpretative guidance, a reference is made to the
syringe as a dispensing instrument. The question arises regarding the regulatory
status of other forms of delivery or dispensing instruments, such as an IV
bag containing excess or residue epinephrine. EPA has not expanded
the definition of a dispensing instrument to include any form of delivery other
than a used syringe. Therefore, only excess or residue epinephrine in a used
syringe is excluded from regulation as a P-listed waste. All excess or residue
epinephrine in other types of dispensing instruments must be managed as a RCRA
hazardous waste.
RCRA
Online # 13718
v. Nitroglycerin Exclusion
In 2001, a revision to the mixture and derived-from rules
(66 FR 27286) excluded all P- and U-listed wastes listed solely for an ignitability,
reactivity and/or corrosivity characteristic (including mixtures, derived-from
and as generated wastes) once they no longer exhibit a characteristic.
Nitroglycerin, P081, is listed solely for its reactivity
characteristic. This action effectively removed medicinal nitroglycerin as
a P-listed waste at the federal level since it is a weak, non-reactive formulation
that does not exhibit the reactivity characteristic.
Nitroglycerin formulations must still be evaluated for the
other characteristics. Some injectables such as nitroglycerin 5 mg/ml in some
formulations fail the ignitability characteristic, which is discussed later
in this Step.
Status of Exclusion in Your State
All states except Iowa and Alaska must adopt the revised
Mixture and Derived-From Rule before weak non-reactive nitroglycerin
is excluded. Hazardous waste regulations are enforced by USEPA in Iowa
and Alaska, therefore this provision was effective immediately in those
states.
Until your state has adopted this provision, nitroglycerin
must be managed as a P081 waste and therefore is still subject to Land
Disposal Restrictions, which are discussed later in Step Two.
Some states, such as Michigan, have chosen to be more
stringent and not adopt this revision. Check with your state regulatory
agency to determine the status of medicinal nitroglycerin in your state.
|
b. U-Listed Wastes (40 CFR Part 261.33(f))
i. Two Necessary Conditions
There are 21 drugs on the U-list (see Table
2: U-Listed Pharmaceuticals). These chemicals are listed primarily
for their toxicity. Similar to a P-listed waste, when a drug waste containing
one of these chemicals is discarded, it must be managed as hazardous waste
if two conditions are satisfied:
(1) The discarded drug waste contains a sole active ingredient
that appears on the U list, and
(2) It has not been used for its intended purpose.
As with P-listed wastes, there is no concentration limit
or dilution exclusion.

ii. Empty Containers of U-Listed Wastes (40 CFR Part
261.7(b)(1))
A container that has held a U-listed waste is considered “RCRA
empty” if two conditions are met:
(1) All the contents have been removed that can be removed
using normal means,
such as drawing liquid out with a syringe;
AND
(2) No more than 3% by weight remains.
If both of these criteria are not met, the container must
be managed as hazardous waste. Any residues removed from the empty container
must be managed as hazardous waste.
Normal
means are practices commonly employed industry-wide to remove the material
from that type of container, such as pouring, pumping, aspirating, and draining
(40 CFR Part 261.7(b)(1)(i))
c. Characteristic Hazardous Waste (40 CFR Parts 261.21 261.24)
In addition to the P- and U- listed wastes, a waste is considered
hazardous under RCRA if it possesses at least one of four unique and measurable
properties or characteristics:
- Ignitability
- Corrosivity
- Reactivity, and
- Toxicity
As the generator, you are responsible for determining whether
a drug formulation that is intended for discard exhibits one of the four characteristics
through testing or through knowledge of the drug formulation. Once a characteristic
waste no longer exhibits any of these properties, it is no longer considered
a hazardous waste. However, RCRA places certain restrictions on the manner
in which a waste can be treated (See What is Treatment? below).
i. Ignitability: D001 (40 CFR 261.21)
The objective of the ignitability characteristic is to identify
wastes that either present a fire hazard under routine storage, disposal, and
transportation or are capable of exacerbating a fire once it has started. There
are several ways that a drug formulation can exhibit the ignitability characteristic.
- Aqueous drug formulations containing 24 percent or more
alcohol by volume and having a flashpoint of less than 140 degrees F or 60
degrees C must be managed as ignitable hazardous waste. Aqueous refers to
a solution containing at least 50 percent water by weight. Since flashpoint
data is somewhat hard to obtain, you should consider managing all waste formulations
containing 24% or more alcohol as ignitable hazardous waste. Many drugs are
relatively insoluble in water and require alcohol to keep them in solution.
- Liquid drug formulations, other than aqueous solutions
containing less than 24 percent alcohol, with a flashpoint of less than 140
degrees F or 60 degrees C must be managed as ignitable hazardous waste. Being
a non-aqueous solution, the flashpoint is used to make the hazardous waste
determination.
- Oxidizers or materials that readily supply oxygen to a
reaction in the absence of air as defined by the DOT must
be managed as hazardous waste.
- Flammable aerosol propellants meeting the DOT definition
of compressed gas must be managed as hazardous waste.
Reference
40 CFR 264 Appendix V Examples of Potentially Incompatible Waste Group
6-A Oxidizers
What is Treatment?
-
Diluting an ignitable solution containing greater
than 24% alcohol during the normal course of usage, as in the preparation
of an IV solution, is not considered treatment. Any resulting waste
would not be ignitable hazardous waste.
-
Diluting an ignitable alcoholic solution containing
over 24% alcohol for the purposes of rendering it non-ignitable
is considered treatment. As a hazardous waste generator, you are
not permitted to treat hazardous waste. A treatment, storage and
disposal facility permit, which is generally inappropriate for
hospitals, is required.

ii. Corrosivity: D002 (40 CFR Part 261.22)
Any waste which has a pH of less than or equal to
2 (highly acidic) or greater than or equal to 12.5 (highly basic) exhibits
the characteristic of corrosivity and must be managed as a hazardous waste.
Generation of corrosive pharmaceutical wastes is generally limited to compounding
chemicals in the pharmacy. Compounding chemicals include strong acids, such
as glacial acetic acid and strong bases, such as sodium hydroxide.
Step
9: Locating Your Satellite Accumulation Area includes a discussion on managing
corrosive pharmaceutical waste.
iii. Reactivity: D003 (40 CFR Part 261.23)
Reactive wastes are unstable under "normal" conditions.
They can cause explosions, toxic fumes, gases, or vapors when heated, compressed,
or mixed with water. Nitroglycerin is the only drug that is potentially reactive.
Refer to the section above, entitled Nitroglycerin Exclusion, for an understanding
of the regulatory status of medicinal nitroglycerin.
iv. Toxicity: Multiple D Codes (40 CFR Part 261.24)
Forty chemicals have been included in RCRA as a concern
in a solid waste landfill environment above certain concentrations. Table
3 provides a subset of that list and examples of drug formulations containing
these chemicals and heavy metals. Wastes that exceed these concentrations must
be managed as hazardous waste. The test that determines the ability of these
chemicals and heavy metals to leach in a landfill environment is called the
Toxicity Characteristic Leaching Procedure, or TCLP. If the concentration determined
by the TCLP exceeds the stated limits, the waste must be managed as hazardous
waste.

v. Empty Containers of Characteristic Wastes (40 CFR
261.7)
A container that has held a characteristic waste is defined
as empty in the same manner as a U-listed waste if all of the contents have
been removed that can be removed through normal means and no
more than 3% by weight remains.
Normal
means are practices commonly employed industry-wide to remove the material
from that type of container, such as pouring, pumping, aspirating, and draining
(40 CFR Part 261.7(b)(1)(i))
2. Grappling with Hazardous Waste Combinations
This section provides guidance on how to manage combinations
of hazardous waste and:
- Personal Protective Equipment (PPE) and spill materials
- Regulated Medical Waste (RMW)
- Sharps, and
- Controlled substances.
a. Contaminated Personal Protective Equipment and Spill
Materials
i. Listed Waste
PPE worn to protect employees from exposure to hazardous
chemicals, materials used to perform routine cleaning or decontamination of
Biological Safety Cabinets and glove boxes, and spill clean up materials may
become contaminated with hazardous waste.
According to EPA's contained-in policy ,
the resulting waste has the same regulatory status as the original listed component.
For example, personal protective equipment such as gloves and gowns that is
known to be or suspected of having been contaminated with P- or U-listed hazardous
waste must be managed as hazardous waste. If PPE is routinely worn but does
not appear to have come into contact with listed waste, it is acceptable for
it to be discarded either as trace chemotherapy waste, if its use involved
chemotherapy agents, or in the trash as solid waste.
EPA''s
contained in policy is explained in the following letters: (1) Marcia Williams
to Gary Dietrich (2/9/1987); (2) Sylvia Lowrance to Timothy Fields, Jr. (1/3/1989; RCRA
Online #11387; and, (3) Devereaux Barnes to Norm Niedergang (2/17/1995; RCRA
Online #13732
Any materials used to clean up a hazardous waste spill, such
as the contents of an IV bag of epinephrine, must be managed as hazardous waste
and cannot be discarded in a trace chemotherapy or solid waste container.
Refer to the section below, Distinguishing Between Trace
and Hazardous Chemotherapy Waste, for further discussion of PPE and spill materials
contaminated with chemotherapy agents.
ii. Characteristic Waste
The contained-in policy applies differently to characteristic
hazardous wastes. PPE and spill materials contaminated with characteristic
wastes are hazardous only if the PPE and spill material exhibit a characteristic.
However, it is best to be conservative and manage PPE that has been contaminated
with a flammable waste or a highly corrosive waste as hazardous waste.
Contaminated Personal Protective Equipment
Indications of contaminated PPE include, but are not
limited to:
|
b. Regulated Medical Waste
There will be situations where a combination waste that is
both infectious Regulated Medical Waste and hazardous waste must be managed
by a limited number of vendors that are permitted to handle both waste
streams. The type of dispensing instrument used and the type of drug being
administered both play an important role in determining how the resulting waste
must be managed.
If, for example, bloody tubing or sharps are not disconnected
from an IV bag that contains a partially used P- or U-listed chemical or from
one that no longer contains a P-listed chemical, the waste must be managed
as both RMW and hazardous waste. Fortunately, in
many cases, luer-lock fittings enable the safe disconnection of the tubing
or sharps from the IV bag. Disconnecting the tubing or sharps from the IV bag
avoids the generation of a waste that is both RMW
and hazardous waste and instead enables the management of the tubing or sharps
and IV bag individually as RMW and hazardous waste, respectively.
Arsenic trioxide and physostigmine are drugs that may be
prepared or administered by syringe and as a result may need to be managed
as both hazardous waste and RMW. Some states, such as New York may allow a
waste that is both RMW and hazardous to be handled
as hazardous waste on the basis that hazardous waste is the more protective
category.
c. Sharps
Often partially used syringes, vials or ampules containing
P- or U-listed hazardous chemicals or characteristic hazardous wastes are erroneously
discarded in RMW sharps containers. Generally speaking, most vendors that manage
sharps are not legally permitted to manage RCRA hazardous waste. These vendors
are permitted to treat only infectious waste. As
the generator, it is your responsibility to train staff that these distinct
types of waste are managed differently and must be segregated (e.g., not to
discard hazardous waste or waste that is both RMW and hazardous waste in sharps
containers unless the containers are specially marked as both infectious and
hazardous waste). If hazardous waste is improperly placed in a sharps container,
the container should be relabeled as RMW and hazardous waste and managed by
a vendor that is permitted to handle both waste streams.
Similarly, it is also possible that during a cardiac arrest
code, a vial or ampule of epinephrine may be used and discarded into the sharps
container on the crash cart. In this case, a P-listed drug container, which
remains hazardous unless triple rinsed, is placed into an RMW container. Here
again, the container must be relabeled as an RMW and hazardous waste container
and a vendor that is permitted to handle both waste
streams must be utilized.
d. Controlled Substances (21 CFR Parts 1300 to 1399)
Controlled substances are those drugs regulated by the Drug
Enforcement Administration. They are divided into five schedules based on their
potential for abuse.
Controlled Substance Schedules
-
Schedule I includes drugs that have no accepted
medical use, such as heroin.
-
Schedule II drugs are used medically but have
high abuse potential, such as morphine, and their purchase, storage,
and use requirements are very strictly monitored.
-
Schedules III through V are drugs with decreasing
abuse potential, including sedatives, tranquilizers, and cough
suppressants, such as codeine.
|
Controlled substances must be destroyed so that they are
beyond reclamation and two health care professionals must document the destruction.
Since most hospitals no longer have ready access to incinerators in which to
burn the drugs, the next most efficient way to accomplish this is through drain
disposal.
There are three controlled substances that are on Schedule
IV due to their moderate abuse potential that are also RCRA listed constituents
of concern: (1) Chloral hydrate (U034), (2) Paraldehyde (U182), and (3) Phentermine
(P046). Other controlled substances may be state listed hazardous waste, as
is the case in Minnesota. Be sure to check with your state regulatory agency.
These hazardous controlled substance wastes can be transferred
to a limited number of hazardous waste vendors that are also DEA registrants.
They also may possibly be sewered. You need to request written permission from
your wastewater treatment plant to sewer small amounts of hazardous controlled
substances. Sewering of controlled substances may be prohibited in your state
or municipality. The hazardous waste regulations pertaining to sewering are
described in more detail below in the section entitled, Drain Disposal.
Step
5: Minimizing Pharmaceutical Waste provides examples of controlled substances
that are routinely wasted and alternatives that will minimize generation of
this waste stream.
Step
9: Selecting the Right Vendor(s) contains requirements for hazardous waste
vendors that are also DEA registrants.
Next
Steps contains recommendations for working with DEA to eliminate drain disposal,
understanding the environmental impacts of managing waste pharmaceuticals in
sharps containers and examining the appropriate management of wastes that are
both infectious and hazardous.
Appendix
A: Tools and Resources provides additional information on controlled
substances and DEA requirements.
3. Distinguishing Between Trace and Hazardous Chemotherapy
Waste
a. Terminology
There is a great deal of confusion among the terms chemotherapeutic,
antineoplastic, and cytotoxic. Technically, chemotherapy is therapeutic chemical
treatment. While most commonly used to describe cancer treatment, it was originally
used as an anti-infective term in reference to the use of mercury and arsenic
before the advent of antibiotics. Some journals still refer to antimicrobial
chemotherapy. The term antineoplastic refers specifically to inhibiting or
preventing the growth or development of malignant cells, and is the most specific.
The term cytotoxic is a very general term referring to any chemical that is
toxic to cells. It again has taken on the common meaning of cancer chemotherapy.
To confuse matters more, the pharmaceutical profession tends to equate the
term biohazardous with cytotoxic. Some manufacturers put both “Cytotoxic” and “Manage
as Biohazardous Waste” on the same label. These labels create confusion as
the term “biohazardous” waste should be restricted to the commonly accepted
definition of infectious waste in state blood-borne pathogens regulations,
which are typically items contaminated with pourable, drippable, flakable or
squeezable blood, used or unused sharps, and lancing devices.
Although the term “chemotherapy” technically
refers to any type of drug treatment, it will be used to describe highly
toxic cancer therapy agents in this document.
|
b. Trace Chemotherapy Waste
The federal RCRA regulations do not address trace chemotherapy
waste. There is no recognized distinction between bulk and trace chemotherapy
contamination for P- and U-listed hazardous wastes since there isn't a lower
concentration limit under which these wastes can exit the regulatory system.
Most state regulated medical waste regulations are either
silent or not specific on the definition of trace chemotherapy waste. The original
reference to segregating trace chemotherapy waste is found in an article written
in 1984 by pharmacy personnel at the National Institutes of Health who pioneered
applying the RCRA regulations to antineoplastic wastes. California's
Medical Waste Management Act and Wisconsin's newly revised Medical Waste Rules
identify trace chemotherapy waste and require incineration at a regulated medical
waste facility or other, approved treatment method.
Vaccari,
P; Tonat, K; DeChristoforo, R; GTallelli, J, Simmerman, P. Disposal of antineoplastic
wastes at the National Institutes of Health, AJHP Vol 41 Jan 1984, pp. 87 93.
Refer
to Appendix A: Tools and Resources for information on how
to access the California Medical Waste Management Act and the Wisconsin Medical
Waste Rules.
All chemotherapy paraphernalia should be managed as trace chemotherapy
waste if there has been the potential for exposure to chemotherapy contamination.
Items that are appropriate for management as trace chemotherapy waste include:
- “RCRA empty” vials, syringes, IV bags, and tubing;
- Gowns, gloves, wipes and other paraphernalia associated
with routine handling, preparation, and administration of chemotherapy; and
- Wipes and other materials used during routine cleaning
and decontamination of a Biological Safety Cabinet or glove box (unless alcohols,
phenols or other hazardous materials are used).
c. Hazardous Chemotherapy Waste
One chemotherapy agent is a P-listed constituent of concern
and eight chemotherapy agents are U-listed (See Table 4 below).
Trace chemotherapy containers have long been used to discard listed chemotherapy
drug waste that should be managed as hazardous waste. This is not only illegal
but also inappropriate since trace chemotherapy waste is incinerated at an
RMW incinerator, not a hazardous waste incinerator. RMW incinerators have less
restrictive emissions limits and permit requirements. Discarding “bulk” P-
or U- listed chemotherapy agents as trace chemotherapy waste has been the cause
of substantial enforcement actions and fines and should be one of the first
changes you implement in your pharmaceutical waste management program.
The term “bulk chemotherapy” is not
a regulatory term but is used to differentiate chemotherapy containers
that are not “RCRA empty.”

i. Combination Hazardous Chemotherapy and Regulated
Medical Wastes
The Oncology Nursing Society strongly discourages unhooking
an IV set unless it has been designed to protect employees from exposure. When
a chemotherapy waste that is both RMW and hazardous waste is generated, it
must be managed by a limited number of vendors that are permitted to handle
both waste streams (See the section above on Regulated Medical Waste for information
on combination wastes).
ii. Spill and Decontamination Materials
Any materials used to clean up a hazardous waste spill,
such as the contents of a used chemotherapy spill kit, must be managed as hazardous
waste. This material cannot be discarded in a trace chemotherapy waste container.
If overt contamination of the Biological Safety Cabinet or glove box surfaces
is known or suspected, all cleaning materials should be discarded as hazardous
waste. It is always permissible to manage a waste up to the next hazard class.
When making this decision, you should use good judgment based on how often
the Biological Safety Cabinet or glove box is used and decontaminated. Unless
a closed transfer system such as PhaSeal is being utilized, it is safe to assume
that some chemotherapy contamination occurs with each transfer.
