Reference No. 10-0141
Dear Mr. Menzigian:
This is in response to your e-mail requesting clarification ofthe Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) regarding the regulated medical waste (RMW)
exception in § 173. 134(c)(2) that allows transportation of a stock or culture of a Category
B infectious substance as RMW with laboratory products. You ask ifthe conditions
described in a previous interpretation, i.e., RMW must be a laboratory product and
accepted at a single facility, are required to use the § 173. 134(c)(2) ex~eption.
The answer is no. This exception does not require RMW and laboratory products to be
accepted, or disposeq. of, at a single facility. Your question is based on an interpretation
we issued on March 19,2007 (Reference No. 07-0057) in which we state a private or
contract carrier can use the exception for RMW containing a waste stock or culture of a
Category B infectious substance when carrying "other types ofhazardous materials." You
state the incoming letter for that inquiry listed laboratory products that are not classified as
RMW for disposal purposes by the Environmental Protection Agency (EPA). You also
state that these products usually require disposal at separate hazardous waste facilities
permitted to receive these materials, and generally cannot be accepted for disposal at a
RMW facility.
We issued two interpretations in 2007 concerning this exception,. Reference No. 07-0057,
which you referred to in your request, and Reference No. 07-0094 (7110/07). We
developed these interpretations based on the information submitted by the letter writers.
Upon reviewing your request, we have determined the information you have provided is
not consistent with the information we considered when issuing these previous
interpretations. Therefore, to answer your question, and also provide additional
clarification for these previous interpretations, we present the following transportation
scenarios and our guidance regarding the applicability ofthe RMW exception in
§ 173.134(c)(2) to these scenarios.

<<<PAGE 2>>>

SCENARIO 1:
A private or contract carrier transports Category B infectious substances as RMW in a
motor vehicle used exclusively to transport these materials along with other types of
medical wastes which may not be regulated under the HMR, or are not hazardous but are
typically generated by laboratories, hospitals, and similar facilities. These wastes include:
1) plant and animal waste regulated by the Animal and Plant Health Inspection
Service, U.S. Department ofAgriculture;
2) waste pharmaceutical materials;
3) laboratory and recyclable wastes, such as fixer/developer, amalgam, lead foil, and
disinfectant materials;
4) infectious substances, including Category A infectious substances, that have been
treated to eliminate or neutralize pathogens;
5) forensic materials being transported for final destruction;
6) rejected or recalled health care products; and
7) documents intended for destruction in accordance with Health Insurance Portability
and Accountability Act (HIP AA) requirements.
The carrier believes these types ofwastes are included under the exception prescribed in
§ 173 .134{ c){2) because:
1) these wastes are difficult to identify and segregate from waste cultures and stocks;
2) waste generators may ask their carriers to transport other types ofmedical waste in
addition to waste cultures and stocks;
3) typically waste cultures and stocks are treated to neutralize any infectious
pathogens prior to transportation, although untreated waste cultures and stocks may
also be transported; and
4) all of these waste materials are transported to facilities designated for the disposal
ofmedical waste.
SCENARIO 1 RESPONSE:
The § 173.134{c){~) exception requires that a waste stock or culture of a Category B
infectious substance be transported by a private or contract carrier in avehicle used
exclusively to transport RMW. Under the HMR, "culture" means an infectious substance
containing a pathogen that is intentionally propagated (see § 173.134{a){3». The term
does not include human or animal material collected directly from humans or animals and
transported for research, diagnosis, investigational activities, or disease treatment or
prevention, such as excreta, secreta, blood and its components, tissue and tissue swabs,
body parts, and specimens in transport media (e.g., transwabs, culture media, and blood
culture bottles) (see § 173.134{a){3) and (a){4».
Also, § 173.134{c){2) requires that a waste stock or culture of a Category B infectious
substance be packaged in a rigid non-bulk packaging in conformance with the packaging
requirements in §§ 173.24, I 73.24a and 29 CFR 1910.1030. An exclusive-use vehicle is
2

<<<PAGE 3>>>

one used for the transportation of a single commodity or class of commodities.
Transportation in an exclusive-use vehicle in conformance with the exception prevents
inadvertent contamination ofother types ofmaterials, including non-medical waste
materials. Thus, non-medical waste materials must not be transported on the same vehicle
as RMW that contains a Division 6.2 waste stock or culture. Additionally, ifthe material
meets the definition of another hazard class or if it is a hazardous substance, hazardous
waste, or marine pollutant, it must be offered for transportation and transported in
accordance with the applicable requirements ofthe HMR.
Medical or clinical equipment and laboratory products may be transported on the same
vehicle as a Category B waste stock or culture provided they are properly packaged and
secured against exposure or contamination. While the term "laboratory products" is not
defined in the HMR, the materials listed above are described as being generated from
laboratories, hospitals, and similar facilities. Materials generated at these types offacilities
have a greater opportunity to become cross-contaminated with Division 6.2 materials.
Further, all ofthe materials listed above are transported to facilities designated for the
disposal ofmedical waste. Authorized medical waste disposal facilities are subject to
federal, state, local, and tribal laws regarding the treatment and/or disposal ofmedical
waste and are designed to contain potential biological hazards and prevent their release
into the environment. Transporting these materials to authorized medical waste disposal
facilities minimizes their ability to cross-contaminate other materials. Therefore, it is the
opinion ofthis Office that the materials listed above, which are transported and disposed of
in the manner that was described, may be considered laboratory products for the purposes
of the § 173. 134(c)(2) exception.
SCENARIO 2:
A private or contract carrier transports a Category B waste stock or culture as RMW in a
motor vehicle used exclusively to transport these materials along With soiled linen and
laundry, which mayor may not be hazardous under the HMR, that is typically generated
by laboratories, hospitals, and similar facilities. The Category B waste stock or culture is
delivered to a facility that treats and/or manages Division 6.2 wastes. The soiled linen and
laundry is not transported to a medical waste facility for disposal, but rather, is transported
to a facility that cleans and manages medical laundry. The carrier believes the soiled linen
and laundry are materials included under the § 173.134( c)(2) exception.
SCENARIO 2 RESPONSE:
It is the opinion of this Office that the soiled linen and laundry are not laboratory products
as that term is used and understood for purposes ofthe HMR, and may not be transported
on the same vehicle as a Category B waste stock or culture under the § 173 .134( c )(2)
exception. In our previous response to the Reference No. 07-0094 letter, we stated soiled
linen and laundry are not medical waste as this term is defined in § 173.134(a)(5). Upon
further review, we determined this statement is incorrect; soiled linen and laundry intended
for disposal or reuse that is derived from the medical treatment of an animal or human
3

<<<PAGE 4>>>

meets the HMR definition ofRMW. Therefore, soiled linen or laundry containing a
Category A infectious substance must be classed as an infectious substance and assigned to
identification number UN 2814 or UN 2900, as appropriate. Soiled linen or laundry
containing a Category B infectious substance must be classed as an infectious substance
and assigned identification number UN 3291. '
Notwithstanding, ifthe laundry or medical equipment (not including medical equipment
intended for disposal) conforms to 29 CFR 1910.1030, it is excepted from regulation under
the HMR(see § 173.134(b)(12)(i». We granted this exception in a final rule issued under
Docket No. HM-181G because:
1) laundry is typically segregated from waste materials at the point of generation and
specially handled and reprocessed by employees dealing exclusively with laundry;
2) we believe that OSHA requirements applicable to laundry and medical equipment
provide an adequate level of safety in transportation; and
3) we believe it is unreasonable and impractical to require RMW packaging and hazard
communication for laundry and medical equipment that are intended for reuse (see 60
FR 48780; 9/20/1995).
As we stated in our Scenario 1 Response, non-medical waste materials must not be
transported on the same vehicle as RMW that contains a Division 6.2 waste stock or
culture.
SCENARIO 3:
Most licensed waste facilities are not authorized to receive and treat both RMW and other
types ofwaste products. Therefore, the same wastes packaged and transported on the same
vehicle in the manner described in Scenario I are delivered to different facilities--the
RMW is delivered to facilities authorized to receive RMW, and the other wastes are
delivered to facilities authorized to treat the overall physical properties ofthese wastes but
not the biological hazards they may contain.
SCENARIO 3 RESPONSE:
Although we have previously interpreted the wastes listed in Scenario I as laboratory
products, this exception does not require RMW and laboratory products to be disposed at a
single facility. In addition, please note that delivering RMW materials to locations not
designed to manage these risks may increase the opportunity for their release. You would
need to contact the facilities to determine such regulatory jurisdiction. State regulations
vary. In some states, facilities are state run and in other states, facilities may be regulated
by EPA requirements. Conflicts between the HMR and other federal agency requirements
are resolved through this agency's Office ofChief Counsel. Also, a requirement of a state,
local, or tribal government that conflicts with requirements in the HMR is preempted,
unless otherwise authorized by another Federal statute or a waiver ofpreemption issued by
the Department ofTransportation. This agency makes preemption determinations
applicable to specific non-Federal requirements on a case-by-case basis. Theregulatory
4

<<<PAGE 5>>>

procedures for administrative determinations ofpreemption are set forth in 49 CFR Part
107, Subpart C.
We further recommend that care should be taken when transporting materials on the same
vehicle with a waste stock or culture ofa Category B infectious substance. Waste cultures
and stocks of Division 6.2 materials may remain pathogenic for a longer period oftime
than most medical wastes because they are often disposed with the host media used to
intentionally propogate them. The surfaces ofpackages containing non-contaminated
items may become contaminated by direct or indirect contact (e.g., transfer or
aerosolization) with pathogenic materials emitted from or on the surface ofRMW
packages, their transport containers, or transport vehicles. As a result, clean items within
these packages may inadvertently become contaminated when they come in contact with
the hands or tools used to open them. We recommend when such transportation occurs
that shippers and carriers take steps to prevent the contamination ofthe outer surfaces of
these packages.
I hope this information is helpful. Please contact this office ifyou have additional
questions.

Subject: Hazmat Information Center Feedback: Shippers-General Requirements for Shipments and
Packagings (Sections 173.1 &ndashj 173.476)
Good Morning,
I am looking for an official interpretation on the following question. In a letter dated
March 19,2997 (Ref No. 97-9957), PHMSA makes a determination that a private or contract
carrier can use the exception for medical waste containing stocks/cultures of Category B
infectious agents at 173.134(c)(2)while carrying other types of hazardous materials (as
listed in the referenced letter) provided they meet two conditions: 1) They need to be a
"laboratory product" as explained in the letter and 2) They can be transported to and
accepted at one facility designated for the disposal of medical waste.
The "laboratory products" listed in the Stericycle letter are not classified as medical
waste for disposal purposes by the EPA. These types of "products" usually require disposal
at a separate, permitted hazardous waste facility and, generally, can not be accepted for
disposal at a medical waste facility. Is the acceptance of both the medical waste (as
defined by DOT) and the "laboratory products" at a single facility a requirement to use the
exception at 173.134(c)(2) to transport stock and cultures with "laboratory products"?

Dear Ms. Hoboy:
This responds to your March 9, 2007 letter requesting clarification of the requirements for
transporting regulated medical waste under the Hazardous Materials Regulations (HMR; 49 CPR
Parts 171-180). Specifically, you ask about the exception in § 173.134(c) applicable to the
transportation of waste cultures and stocks and for clarification of the types of ma:erials that may
be transported on the same vehicle as waste cultures and stocks in accordance with the exception.
The exception in § 173. 1 34(c)(2) permits a waste stock or culture of a Category B infectious
substance to be offered for transportation and transported as a regulated medical waste when it is
packaged in a rigid non-bulk packaging conforming to the general packaging requirements of
§§ 173.24 and 173.24a and packaging requirements specified in 29 CPR 1910.10:0 and
transported by a private or contract carrier in a vehicle used exclusively to transport regulated
medical waste. As your letter notes, in a final rule published [insert date] under docket number
HM-226A, we amended the language in this section to insert the phrase "used exclusively to
transport regulated medical waste" in place of the phrase "dedicated to the transpc·rtation of
regulated medical waste".
The change in terminology in § 173.l34(c)(2) was intended to be a non-substantive editorial
change to standardize terminology used throughout the HMR. The terms "dedicated" and "used
exclusively" are synonymous. "Exclusive use" is not defined in the mfR, for other than
transport of radioacti ve materials. As used in the HMR, the terms "dedicated" and "used
exclusively" mean the vehicle is used for the transportation of a single commodity or class of
commodities.
According to your letter, it is difficult to identify and segregate waste cultures and stocks from
other types of medical waste generated by laboratories, hospitals, and similar facilities. You note
that typically waste cultures and stocks are treated to neutralize any infectious pathogens prior to
transportation, although untreated waste cultures and stocks may also be transport.=d. You
indicate that waste generators may ask Stericyle to transport other types of medical waste in
addition to waste cultures and stocks, including:
• Plant and animal waste regulated by the Animal and Plant Health Inspectic'n Service,
U.S. Department of Agriculture;
1111111111111111111 173.134
070057

<<<PAGE 8>>>

• Waste pharmaceutical materials;
• Laboratory and recyclable wastes, such as fixer/developer, amalgam, lead foil, and
disinfectant materials;
• Infectious substances, including Category A infectious substances, that h~lve been treated
to eliminate or neutralize pathogens;
• Forensic materials being transported for final destruction;
• Rejected or recalled health care products; and
• Documents intended for destruction in accordance with HIPAA requirements.
You indicate that all these waste materials are transported to facilities designated for the disposal
of medical waste.
As described above, the exception in § 173.134(c)(2) pelmits Category B waste cultures and
stocks to be transported as regulated medical waste in a rigid non-bulk packaging conforming to
certain general packaging requirements when transported by a private or contract carrier in a
vehicle used exclusively to transport regulated medical waste. An exclusive-use vehicle is one
used for the transportation of a single commodity or class of commodities; transpJrtation in an
exclusive-use vehicle in accordance with the exception prevents inadvertent contamination of
other types of materials, including non-medical waste materials. The operations ;IOU describe for
the transportation of waste cultures and stocks appear to meet the intent of this exception. While
the materials you transport on the same vehicle as waste cultures and stocks are nJt regulated
medical waste, as that term is defined in the HMR, all the materials are considered medical waste
and are transported to facilities designated by local authorities and designed for the disposal of
medical waste.
Further, under § 173. 134(c){2), you may transport medical or clinical equipment and laboratory
products on the same vehicle as the waste cultures and stocks covered by the exc{:ption, provided
they are properly packaged and secured against exposure or contamination. The term
"laboratory products" is not defined in the HMR. However, the materials you describe are
generated from laboratories and health care facilities and, thus, may be considered laboratory
products for the purposes of the exception.
Therefore, it is the opinion of this Office that the transportation operation you describe is
consistent with the terms of the exception in § 173.134(c){2). Therefore, you ma;1 transport the
types of medical waste described in your letter on the same vehicle you use to transport waste
cultures and stocks.

RE: FINAL RULE HM 226A - INTERPRETATION OF "EXCLUSIVE" MEDICAL
WASTE CARRIER UNDER 49 CFR 173.134
Dear Mr. Mazzullo:
I am writing in referenc;;e to a recent language change under Final Rule HM 226A. In this
final rule there is a section' relating tothetiansportatiori of regulated medical waste.
Specific section reference is 49 CFR 173.134 (c)(ii)(2) "[Category B waste culture or
stock] transported as regulated medical waste when it is packaged in a rigid non-bulk
packaging conforming to the general packaging requirements of 173.24 and I 73.24a and
packaging requirements under 29 CFR 1910.1030 and transported by a private or contract
carrier in a vehicle used exclusively to transport regulated medical waste." Prior to this
change the term "dedicated" was llsed instead of "exclusively". Based on the literal
interpretation of these regulations it would mean that materials other than regulated
medical waste. could n,ot .be,011 the vehicle ,!it t,he same time,
Although, we recognize that the mixed cultures and stock materials which may be present
in the containers is minimal and often more specifically from lab type environments, the
potential still exists. It is also typical that wastes generated in these environments are
pretreated prior to being disposed of in the regulated medical waste. However, due to
the way that generators package their waste to take advantage of this exception, it would
be difficult to ensure exclusivity for these materials alone.
We are requesting clarification that this new term does not change the intent of the
regulation. Prior to this, the interpretation was that as a private carrier, primarily
dedicated to the transport of regulated medical waste, other materials could be present on
the vehicle. However, there are other waste streams that are transported as a service to
generators for the safe and efficient transport of their waste materials. All :Irivers and
employees are fully trained on the proper handling, transport and'emergency response to
these other waste materials. This provides generators with an'efficient am compliant
option for transporting their wastes. Other such wastes which generator's ma;1 request to
be transported that are not necessarily regulated medical waste by definition may include:
• us Department of Agriculture - Animal and Plant Health Inspection Service Wastes
defined under 7 CFR as regulated garbage, including plant and an,mal waste,
and are required to have specific packaging, documentation and destruction
requirements
Stericycle, Inc.
2333 Waukeqan Road, Suite 300 • Bannockburn, IL 60015 ••• www,5tericyde.ccm

<<<PAGE 11>>>

• Waste pharmaceuticals - phannaceutical materials which are meant for final
destruction and no longer have value by manufacturer definition; packaged in
accordance with regulations and separately documented as required
• Lab and Recyclable wastes for example fixer/developer for recycling, amalgam for
recycling, lead foil for recycling, disinfectant materials etc. - Packaged in :lccordance
with regulations and separately documented as required
• Treated Category A infectious substances which generators chose to over classify
• Documents for clestruction under HIP AA requirements
• Evidence materials - non weapon law enforcement materials sent for final
destruction
• Off specification products from manufacturers due to rejection or recal., nonnally
considered solid waste, which is transported for destruction
Current needs of the industry and generators are that other waste streams, which are also
classified, marked and packaged appropriately, could be transported with regulated
medical waste without compromising public health and safety. The ability t::> transport
these materials together would also support greater compliance of proper segn: gation and
characterization of materials by the generator leading to a more environmentally
responsible disposal of these materials.
We woutd like to (;/arify that these additional Wasterriaterilils can be ttansJ:oited with
regulated medical waste so long as all materials are properly classified, marked and
packaged appropriately. Additionally, we assume that it was not the intent of the change
in words, to change the practices of the medical waste industry. We appreciate your
consideration on this matter. Please feel free to contact me if you have liny further
questions at 847-943-6685/shoboy@stericycle.com.

Dear Mr. Petrullo:
This responds to your May II, 2007 e-mail and May J1, 2007 telephone conversation with
Ms. Eileen Edmonson of my staff concerning requirements in the Hazardous Materials
Regulations (HMR; 49 CFR Parts 171-180) applicable to the transportation of regulated
medical waste (RMW). Specifically. you ask for a clarification of our letter to Ms. Selin
Hoboy, Stericycle, Inc. (Reference No. 07-0057; March 19,2007) concerning the dedicated
vehicle exceptions in § 173.134(c)(2) of the HMR.
The exception in § 173.134(c)(2) permits Category B waste cultures and stocks to be
transported as regulated medical waste when packaged in a rigid non-bulk packaging
conforming to certain general packaging requirements and transported by a private or contract
carrier in a vehicle used exclusively to transport RMW. An exclusive-use vehicle is one used
for the transportation of a single commodity or class of commodities. Transportation in an
exclusive-use vehicle in accordance with the exception prevents inadvertent contamination of
other types of materials. including non-medical waste materials.
In our March 19.2007 letter to Stericycle, Inc., on this subject, we addressed a question
concerning the transportation of other types of materials on the same vehicle as Category B
waste cultures and stocks: (1) plant and animal waste regulated by the Animal and Plant
Health Inspection Service, U.S. Department of Agriculture; (2) waste pharmaceutical
materials; (3) laboratory and recyclable wastes, such as fixer/developer. amalgam. lead foil.
and disinfectant materials; (4) infectious substances. including Category A infectious
substances. that have been treated to eliminate or neutralize pathogens; (5) forensic materials
being transported for final destruction; (6) rejected or recalled health care products; and (7)
documents intended for destruction in accordance with HIPAA requirements. While not
considered regulated medical waste. as that term is defined in the HMR, all of the listed
materials are considered medical waste as that term is usually defined and. according to the
information provided by Stericycle. are transported to facilities designated by local authorities
and designed for the disposal of medical waste. Moreover. under § 173.l34(c)(2). medical or
clinical equipment and laboratory products may be transported on the same vehicle as the
waste cultures and stocks covered by the exception. provided they are properly packaged and
secured against exposure or contamination. The term "laboratory products" is not defined in
the l;IMR. However. the materials described carlier in this paragraph are generated from
1111111111111111111
070094

<<<PAGE 13>>>

laboratories and health care facilities and, thus, may be considered laboratory products for the
purposes of the exception. For these reasons, we determined that the types of medical waste
described in our March 19 letter may be transported 'on the same vehicle as waste cultures and
stocks in accordance with the exception in § 173.134(c)(2).
You ask whether soiled linen and laundry may also be transported on the same vehicle as
waste cultures and stocks under the exception provided in § 173.134( c). The answer is no.
Soiled linen and laundry are not medical waste and are not transported for disposal at a
medical waste facility; further, soiled linen and laundry are not laboratory products as that
term is used and understood for purposes of the HMR.
Your email refers to the transportation of soiled healthcare linen on the same vehicle as
RMW. We note in this regard that the exception in § I 73.134(c) applies only to the
transportation of waste cultures and stocks. The HMR do not require shipments of most
RMW to be transported on vehicles used exclusively for such transportation. For other than
waste cultures and stocks, there are no restrictions on the types of materials that may be
transported on the same vehicle as RMW. Thus, you may transport soiled healthcare linen,
clean linen, hospital supplies, or other materials on the same vehicle as RMW, provided the
shipment does not contain waste cultures and stocks. For purposes of the HMR, "culture"
means an infectious substance containing a pathogen that is intentionally propagated. The
term does not include human or animal material collected directly from humans or animals
and transported for research, diagnosis, investigational activities, or disease treatment or
prevention, such as excreta, secreta, blood and its components, tissue and tissue swabs, body
parts, and specimens in transport media (e.g. , transwabs, culture media, and blood culture
bottles). (See § I73.1 34(a)(3) and (a)(4).)
Care should be taken, however, when transporting materials on the same vehicle as RMW.
The surfaces of packages containing non-contaminated items may become contaminated by
direct or indirect contact (e.g., transfer or aerosolization) with pathogenic materials emitted
from or on the surface of RMW packages, or their transport containers or transport vehicles.
As a result, the clean items within the packages may inadvertently become contaminated
when they come in contact with hands or tools used to open them. We recommend when such
transportation occurs that shippers and carriers take steps to prevent the contamination of the
outer surface of these packages.
I hope this satisfies your request.

Subject: Follow-Up On RMW Transport Interpretations
Hello Eileen,
It was very nice seeing you again in Atlanta. Been many years it seems from the time in San Diego.
Here below I am copying the e-mail I just sent to William Stevens, Senior Hazardous Materials
Enforcement Specialist, for more clarification. I know you said you were waiting for a response on some
issues from Susan in your office. I am not sure if her response will include the matter that we are
discussing below. What do you suggest we do as a small company to address this situation? Do we ask
for a Permit or Exclusion? It seems to me that in the U.S. there are relatively few "Destination/or
Designated Facilities" than receive, store, and process everything on a tnlck carrying RMW. Case in
point is that even if just RMW and no linen or HIPP A documents, the incinerables are going to go to
another facility and maybe that facility is in a different state. Please read my letter below, and then tell
me what we should do. Thank you very much .......... .
Hello Mr. Stevens,
I wOllld like to correspond "I'itll you so that I may work through some Qf tile issues discovered while you
and I discussed RMW transport in length thursday after the Medical Waste conference in Atlanta.
Initially, I would like you to summarize for me the "designated vehicle" issue we discussed with the CFR
sites, so that I may look them up and re-familiarize myself with them.
You will remember that we discussed transporting RMW with healthcare linen. We have two plants
within 15 miles ofone another and so the unloading ofthe RMWfirst and then traveling to the laundry
plant to unload the soiled healthcare linen is the most efficient for ollr small operation. I understand
that there is an interpretation recently that Stericycle has in writing saying that some materials like
fixer/developer, HIPPA docs, and healthcare linen may be transported together with RMW. You made
the point that you would write a violation for sLlch activity. I believe. We would ofcOLlrse like to have a
consenslls and through the last 10 years or so, we have had opinions from the State authorities and
some at the D. O. T. that stated that these materials we deal with are very simi liar ill waste
characteristics/soil, and with proper packaging and segregation that they are homogeneousfor
transport.
I appreciate YOllr taking the time to assist liS with this. Two questions before I close:
1) I wonder also ifthere has the been a change ill the regs or illterpretatiolls due to the re-aligllment
with the W.H. O. Has there?
2) Can RMW be manifested on a "Bill ofLading" /Ising the words "NOli-hazardous Waste"?
I look forward to the CFR reference locations for our education and yOllr opinion conceming these
areas ofconcern.
Thanks
