PUBLISHER’S NOTE: The secretary of state
has determined that the publication of the
entire text of the material which is incorporated by reference as a portion of this rule
would be unduly cumbersome or expensive.
This material as incorporated by reference in
this rule shall be maintained by the agency at
its headquarters and shall be made available
to the public for inspection and copying at no
more than the actual cost of reproduction.
This note applies only to the reference material. The entire text of the rule is printed
here.
(1) Applicability.
(A) Definition. Infectious waste means
waste capable of producing an infectious disease because it contains pathogens of sufficient virulence and quantity so that exposure
to the waste by a susceptible human host
could result in an infectious disease. These
wastes include isolation wastes, cultures and
stocks of etiologic agents, blood and blood
products, pathological wastes, other contaminated wastes from surgery and autopsy, contaminated laboratory wastes, sharps, dialysis
unit wastes, discarded biological materials
known or suspected to be infectious; provided, however, that infectious waste does not
mean waste treated to department specifications.
1. For the purposes of this chapter, a
generator means any single office (doctor’s
office, dentist’s office, and the like) or facility (hospital, nursing home, mortuary, and the
like), whose act or process first causes an
infectious waste. For purposes of tracking
and fees, a transfer station permitted as an
infectious waste processing facility becomes
the generator when the infectious waste is
transported for further processing.
2. Small quantity generators, i.e., persons generating one hundred kilograms (100
kg) or less per month of infectious waste,
shall refer to 19 CSR 20-20.010 for the
Department of Health definition of those categories of waste to be managed as an infectious waste.
3. Except as provided in paragraph
(1)(A)2. of this rule, infectious waste shall
include the following wastes from specific
and non-specific sources:
A. Isolation wastes. Wastes generated
by patients who have communicable diseases
which are capable of being transmitted to others via those wastes;
B. Contaminated surgical, dialysis
and laboratory wastes. Wastes generated by
surgery, dialysis and laboratory departments
in the process of caring for patients who have
communicable diseases which are capable of
being transmitted to others via those wastes;
C. Cultures and stocks of infectious
agents and associated biologicals. Cultures
and stocks of infectious agents shall be designated as infectious waste when discarded
because of the high concentrations of
pathogenic organisms typically present in
these materials. Included in this category are
all cultures and stocks of infectious organisms as well as culture dishes and devices
used to transfer, inoculate and mix cultures;
D. Blood and blood products. All discarded human blood and blood products,
including serum, plasma and other components known or suspected to be contaminated
with a transmissible infectious agent; except
that the term “blood products” does not
include patient care waste such as bandages
or disposable gowns that are lightly soiled
with blood or other body fluids, unless such
wastes are soiled to the extent that the generator of the wastes determines that they should
be managed as infectious wastes;
E. Pathology wastes. These wastes
include tissues, organs, body parts and body
fluids that are removed during surgery and
autopsy. All such wastes shall be considered
infectious waste. Also included are animal
carcasses, body parts and bedding from animals contaminated with infectious agents
capable of being transmitted to a human host.
Nothing in this section shall supersede the
disposal requirements for dead animals as set
forth in Chapter 269, RSMo; and
F. Sharps. Discarded sharps, including hypodermic needles, syringes and scalpel
blades. Broken glass or other sharp items that
have come in contact with material considered infectious by definition are also included.
(B) Disposal of Infectious Waste. All
sharps shall be packaged in rigid, leak-resistant and puncture-resistant containers and
sealed prior to disposal.
1. Infectious waste treated to render it
innocuous may be disposed as a solid waste
provided the treater certifies to the transporter, if other than the generator, and certifies to the sanitary landfill operator or processing facility operator that the waste has
been rendered innocuous as required by section 260.203, RSMo. (Note: Treated infectious waste is not required to be transported
in accordance with the requirements of section (4) of this rule.)
2. Certification of treated infectious
waste, at a minimum, shall contain the following information: the name, mailing
address, location (when different from the
mailing address) and phone number of the
office/facility treating the infectious waste;
the printed name and the signature of the
facility/office manager or person responsible
for the treatment process; a brief description
of the treated waste (sharps in metal containers, sharps in heavy gauge plastic containers,
incinerator ash, laboratory wastes in autoclave bags); and a brief description of the
method(s) of treatment (for example, steam
sterilization, incineration, disinfection with
bleach solution). In addition to these minimum requirements, the generator need only
include a statement that the waste has been
managed in accordance with the Missouri
Solid Waste Management Law and rules and
may legally be placed in a sanitary landfill.
The certification shall be revised when
changes in the operation of the office/facility
result in a change to the information required
by this paragraph.
3. In addition to the requirements of
paragraphs (1)(B)1. and 2. of this rule, incinerator residue from a permitted infectious
waste processing facility shall be considered
to be a special waste. and handled accordingly. Prior to departmental approval, and at a
minimum, every six (6) months after that, the
incinerator residue shall be tested for hazardous waste characteristics as per 40 CFR
part 261 subpart C, as incorporated in 10
CSR 25-4.261, as applicable.
(C) Exemptions.
1. Any person who treats infectious
waste generated on-site to render the waste
innocuous or a hospital exempted from the
requirements of a permit in paragraph
(1)(C)5. of this rule may dispose of the treated waste as specified in subsection (1)(B) of
this rule.
2. This rule shall not apply to generators
of infectious waste at a single-family residential premise or a single-family dwelling unit
provided those wastes are generated on-site
and disposed with the generator’s residential
solid waste and provided sharps are packaged
as required in subsection (1)(B) of this rule.
3. A person generating one hundred
(100) kg or less per month of infectious waste
as defined by 19 CSR 20-20.010 and who
transports his/her own infectious waste for
processing is exempt from the transportation
and fee requirements of this rule, except that
the vehicle used for transport of the infectious
waste shall be a closed and secured vehicle.
4. A generator of infectious waste who
operates a single or multiple site research
facility for research and experimental activities as defined in section 174 of the 1986
Internal Revenue Code, who generates such
waste as a part of research and experimentation activities, who manages such waste onsite and who accepts no infectious waste from
off-site, is exempt from the infectious waste
processing facility permit requirements of
this rule. The generator may accept infectious
waste from other sites of the parent research
company located in Missouri but shall not
accept infectious waste from other sources
and shall comply with all other requirements
and provisions of the Missouri Solid Waste
Management Law and the rules and regulations promulgated thereunder. The University
of Missouri Ellis Fischel Cancer Center and
the other facilities of the University of Missouri-Columbia shall be considered a multiple site research facility for the purposes of
this rule.
5. Hospitals. Hospitals as defined in
section 197.020, RSMo are exempted from

permit or a solid waste processing facility
construction and operating permit for the
treatment of infectious waste except as provided in 19 CSR 30-20.021. Hospitals may
accept infectious waste from those generators
as provided by 260.203.9, RSMo upon
approval of the Department of Natural
Resources and the Department of Health. A
notice of intent to accept the waste for treatment shall be hand delivered or sent by certified mail to the Department of Natural
Resources and to the Department of Health.
Failure of either department to respond to
such a request by issuing a certification of
approval or a denial within ninety (90) days
constitutes approval. The request for approval
shall include a report containing at a minimum the following information:
(I) A copy of the infectious waste
management plan for the handling and treatment of infectious waste as required by 19
CSR 30-20.021;
(II) A clause that infectious waste
shall be accepted at the hospital only if it is

Missouri; and
(III) Off-site in quantities as provided in 19 CSR 30.
6. Pharmacies, as defined in Chapter
338, RSMo, and home health agencies, as
defined in Chapter 197, RSMo, are exempt
from the infectious waste processing facility
permitting requirements of this rule provided
that the only waste accepted is single dose
hypodermic units presented in person by
small quantity generators as defined by paragraph (1)(A)2. of this rule. Pharmacies and
home health agencies operating under this
exemption shall be limited to a maximum of
ten (10) kilograms of infectious waste on-site
at any time and process no more than one
hundred (100) kg of infectious waste per
month. All waste received under this exemption must be managed in accordance with this
rule.
7. For the purpose of this rule, a person
working on behalf of a home health agency
and who transports infectious waste from the
patient's residence to the agency (as a central
collection point) will be considered an extension of that agency and exempt from the
transportation and fee requirements of this
rule, except that the vehicle used for transport
of the infectious waste shall be a closed and
secured vehicle.
(2) Packaging of Infectious Waste. Prior to
transport, all infectious waste shall be placed
in rigid or semi-rigid, leak-resistant containers clearly marked with the universal biohazard symbol prominently displayed and labeled
Infectious Waste or Biohazard Waste and
sealed. All containers shall be closed in such
a manner as to completely contain all waste
and the outside of the container shall be kept

(5) Permitted Infectious Waste Processing
Facility. This section sets forth requirements
for solid waste processing facilities permitted
for the treatment or other processing of infectious waste. A report shall be submitted to the
department containing plans, as defined in 10
CSR 80-2.010, addressing the requirements
of sections 260.200-260.345, RSMo and 10
CSR 80.
(A) Treatment Facility. An infectious waste
processing facility permitted for the treatment
of infectious waste means a facility that has
received a solid waste processing facility permit as provided in sections 260.200-260.345,
RSMo and 10 CSR 80-2.020, 10 CSR 805.010, and this rule. The solid waste processing facility construction and operating permit
shall specifically allow for the treatment of
infectious waste as provided by this rule. Two
(2) treatment technologies are approved for
the treatment of infectious waste by permitted
facilities—incineration and steam sterilization. Chemical sterilization and other types of
treatment may be approved by the department
on a case-by-case basis.
1. Permitted infectious waste incinerators shall be multi-chambered and be
designed to provide complete combustion for
the type of waste introduced into the incinerator. The incinerator shall achieve a minimum temperature of one thousand eight hundred degrees Fahrenheit (1800 °F) in the
secondary chamber with a minimum retention time of one-half (1/2) second in the secondary chamber. Automatic controls that lock
out the load system if the secondary chamber
is not up to the minimum temperature and
automatic, continuous temperature recording
charts for the secondary chamber shall be
equipped on the incinerator and utilized during any infectious waste treatment process.
A. The operator shall visually inspect
each batch of ash from batch-type ash
removal systems prior to disposal. The operator shall visually inspect the ash from continuous ash removal systems a minimum of
once per hour during operation.
B. Any partially combusted organic
materials observed will be noted in the facility log. The facility manager shall be notified
and corrective action taken. The corrective
action and new ash observations shall be
noted in the facility log.
C. Amount of waste treated each hour
shall be recorded in the facility log by weight.
D. The plans shall include a statement
quantifying the maximum amount, by weight,
of infectious waste to be accepted each
month.
E. The plans shall contain procedures
for the handling of spills during unloading,
storage, and processing of the infectious
waste, and the plan will be implemented
immediately upon discovery of any spill.
F. A solid waste technician trained in
the handling of infectious waste and in the
operation of the incinerator shall be on-site
during any treatment process. Evidence of
training shall be maintained on-site. The
plans shall contain an outline of the training,
including the name and qualifications of the
person(s) providing the training.
2. Steam sterilization by permitted facilities using autoclaves is an acceptable means
of treating infectious waste when operated at
sufficient temperatures for adequate periods
of time to kill infectious agents present in the
waste. Automatic continuous time and temperature recording charts shall be utilized on
each unit during operation. Units shall be
operated according to manufacturer’s recommendations.
A. During initial operational testing,
four (4) waste charges representing the maximum amount of waste to be processed in any
charge shall be treated. Each charge shall
contain all types of waste that are to be treated at the facility and shall be packaged as the
waste will be packaged for treatment during
normal operations. For each of the four (4)
waste charges, three (3) biological indicators
approved by the department (such as three (3)
vials of Bacillus stearothermophilus), shall be
placed inside separate containers of simulated
waste (that is, sharps containers, autoclaveable bags), distributed throughout the waste
charge prior to treatment, recovered after
treatment, cultured, and analyzed. Any positive reading constitutes a failure of the treatment process and shall require corrective
action and retesting in accordance with this
subparagraph.
B. Each sterilizer shall be tested each
week by placing one (1) department-approved
biological indicator inside a waste container
prior to treatment. The biological indicator
shall be recovered, cultured, and analyzed. A
positive indicator constitutes a failure of the
treatment process. The sterilizer shall not be
used to treat infectious waste until corrective
action has been taken and results verified.
Upon completion of corrective action, the
sterilizer shall be retested in accordance with
subparagraph (5)(A)2.A. of this rule. Results
of biological indicator tests and any corrective action shall be recorded in the facility
log.
C. Amounts of waste treated each
load shall be recorded in the facility log by
weight.
D. Sharps that were treated by steam
sterilization shall be packaged in rigid, leakresistant and puncture-resistant containers,
and sealed prior to disposal.
E. Sharps that have been rendered
innocuous by an approved method and that
have been shredded so as not to pose a puncture hazard are not required to be transported, packaged, or stored in rigid, semi-rigid,
leak-resistant or puncture-resistant containers. Such sharps may be disposed of in a sanitary landfill as a solid waste.
F. The plans shall include a statement
quantifying the maximum amount, by weight,
of infectious waste to be accepted each
month.
G. The plans shall contain procedures
for the handling of spills during unloading,
storage, and processing of the infectious
waste, and the plan will be implemented
immediately upon discovery of any spill.
H. A solid waste technician trained in
the handling of infectious waste and in the
operation of the steam sterilizer shall be onsite during any treatment process. Evidence
of training shall be maintained on-site. The
plans shall contain an outline of the training,
including the name and qualifications of the
person(s) providing the training.
(B) Transfer Stations. To facilitate consolidation of shipments prior to further transport,
infectious waste may be transported to a
transfer station as defined in 10 CSR 802.010. A solid waste processing facility permitted as a transfer station for infectious
waste means a facility that has received a
solid waste processing facility construction
and operating permit as provided in sections
260.200–260.345, RSMo and 10 CSR 802.020, 10 CSR 80-5.010, and this rule. The
solid waste processing facility construction
and operating permit shall specifically allow
for the acceptance of infectious waste.
(C) Storage. Infectious waste at infectious
waste processing facilities shall be placed in a
storage area or processing area as approved
by the department in the operational report
and plans.
1. Processing area. Infectious waste at
an infectious waste processing facility may be
placed into the processing area provided the
facility is operational and no infectious waste
shall be stored in the processing area at the
end of the operating day. For those facilities
operating continuously, no infectious waste
shall be kept in the processing area for more
than twenty-four (24) hours.
A. The plans shall contain procedures
for the handling of spills in the processing
area.
B. The processing area shall have a
floor sloped to drains connected to the sanitary sewage system or a collection device.
