Summary
In this 74th ITC Report, the ITC is
revising the Toxic Substances Control
Act (TSCA) section 4(e) Priority Testing
List by adding 15 High-Priority
Substances and 24 organohalogen flame
retardants and requesting that EPA add
these chemicals to the TSCA section
8(d) Health and Safety Data Reporting
rule. The ITC is also requesting that EPA
add the other five High-Priority
Substances and six organohalogen flame
retardants specified in Unit III. of this
report, and currently on the Priority
Testing List, to the Health and Safety
Data Reporting rule.
I. Background
The ITC was established under
section 4(e) of TSCA and recommends
to EPA chemical substances and
mixtures to be given priority
consideration for the development of
information under TSCA section 4(a).
These recommendations are made in the
form of a list known as the Priority
Testing List. The ITC revises the Priority
Testing List as it determines necessary
and transmits such revisions to the EPA
Administrator with the ITC’s rationales
for the revisions. ITC Reports are
available from regulations.gov https://
www.regulations.gov after publication in
the Federal Register and on EPA’s
website https://www.epa.gov/assessingand-managing-chemicals-under-tsca/

reports. The ITC produces its revisions
to the Priority Testing List with
administrative and technical support
from EPA staff, ITC Members, and their
U.S. Government organizations. ITC
members and staff are listed at the end
of this report.
II. TSCA Section 8(d) Health and Safety
Data Reporting Rule
Following receipt of the ITC’s report
(and the revised Priority Testing List) by
the EPA Administrator, and following
the public comment period on this
report and consideration of any such
comments received, EPA’s Office of
Pollution Prevention and Toxics (OPPT)
may add the chemicals from the revised
Priority Testing List to the TSCA section
8(d) Health and Safety Data Reporting
rule (40 CFR part 716) (Ref. 1). The
Health and Safety Data Reporting rule
requires manufacturers (including
importers) of chemical substances and
mixtures added to the Health and Safety
Data Reporting rule to submit lists and
copies of unpublished health and safety
studies to EPA.
III. Activities During the May 2020 ITC
Meeting and Revisions to the TSCA
Section 4(e) Priority Testing List:
Addition of 15 High-Priority Substances
and 24 Organohalogen Flame
Retardants
During the May 2020 ITC meeting, the
ITC discussed the 20 High-Priority
Substances designated by EPA under
TSCA section 6(b) and informationgathering options for these substances.
Five of these High-Priority Substances
were already on the Priority Testing List,
added previously by the 69th ITC
Report (Ref. 2). The ITC discussed
adding the remaining 15 High-Priority
Substances to the Priority Testing List
and also requesting the addition of those
chemical substances to the TSCA
section 8(d) Health and Safety Data
Reporting rule (40 CFR part 716) so that
EPA may obtain unpublished health and
safety studies on all 20 High-Priority
Substances.
During the May 2020 ITC meeting, the
ITC also discussed adding a group of
organohalogen flame retardants to the
Priority Testing List to obtain
unpublished health and safety studies
on 30 organohalogen flame retardants,
six of which were previously added to
the Priority Testing List by the 69th ITC
Report.
The 15 High-Priority Substances and
24 organohalogen flame retardants being
added to the Priority Testing List are
listed in Table 1 of this unit. The
remainder of the chemical substances
and mixtures on the Priority Testing List
is provided in Table 2 of this unit.
PO 00000
Frm 00032
Fmt 4703
Sfmt 4703

The five High-Priority Substances that
were already listed on the Priority
Testing List are 1,1-dichloroethane (CAS
No. 75–34–3), 1,2-dichloroethane (CAS
No. 107–06–2), ethylene dibromide
(CAS No. 106–93–4), tris(2-chloroethyl)
phosphate (TCEP) (CAS No. 115–96–8),
and phosphoric acid, triphenyl ester
(TPP) (CAS No. 115–86–6). The ITC is
also requesting the addition of these
chemical substances to the TSCA
section 8(d) Health and Safety Data
Reporting rule so that EPA can obtain
unpublished health and safety studies
on these substances.
The six organohalogen flame
retardants that were already listed on
the Priority Testing List are bis(2ethylhexyl) tetrabromophthalate (CAS
No. 26040–51–7), 2-ethylhexyl 2,3,4,5tetrabromobenzoate (CAS No. 183658–
27–7), phosphoric acid, 2,2bis(chloromethyl)-1,3-propanediyl
tetrakis(2-chloroethyl) ester (CAS No.
38051–10–4), tris(2chloroisopropyl)phosphate (CAS No.
13674–84–5), tris(2-chloropropyl)
phosphate (CAS No. 6145–73–9), and
tris(1,3-dichloro-2-propyl) phosphate
(CAS No. 13674–87–8). The ITC is also
requesting the addition of these
chemical substances to the TSCA
section 8(d) Health and Safety Data
Reporting rule so that EPA can obtain
unpublished health and safety studies
on these substances.
Chemical Substances Added to the
Priority Testing List
1. High-Priority Substances
i. Recommendation. The ITC is
adding the 15 High-Priority Substances
listed in Table 1 of this report to the
Priority Testing List. The ITC is also
requesting the addition of these
chemical substances to the TSCA
section 8(d) Health and Safety Data
Reporting rule so that EPA can obtain to
obtain unpublished health and safety
studies on health effects, physical/
chemical properties, environmental fate,
environmental effects, and exposure.
ii. Rationale for recommendation. The
20 High-Priority Substances identified
in this report have been designated
High-Priority under TSCA section 6(b)
because EPA has found that each of
these chemical substances may present
an unreasonable risk of injury to health
or the environment under the
conditions of use for that chemical
substance (Ref. 4). The development of
information on these chemical
substances under TSCA section 4(a) will
enable EPA to inform its risk evaluation
findings of whether any of these HighPriority Substances present an
unreasonable risk of injury to health or
E:\FR\FM\28APN1.SGM
28APN1
jbell on DSKJLSW7X2PROD with NOTICES
22416
Federal Register / Vol. 86, No. 80 / Wednesday, April 28, 2021 / Notices
the environment under the conditions of
use for each of these chemical
substances.
iii. Supporting information. TSCA
section 6 requires EPA to address
existing chemical substances with a
three-stage process. The three stages of
EPA’s process for ensuring there are no
unreasonable risks associated with the
conditions of use of existing chemical
substances are (1) prioritization, (2) risk
evaluation, and (3) risk management.
Prioritization and risk evaluation are
carried out in accordance with
procedural regulations at 40 CFR part
702, subparts A and B, respectively.
During prioritization EPA designates a
chemical substance as either HighPriority for risk evaluation, or LowPriority for which risk evaluation is not
warranted at the time. A High-Priority
Substance is defined under TSCA
section 6(b)(1)(B)(i) as ‘‘a chemical
substance that the Administrator
concludes, without consideration of
costs or other nonrisk factors, may
present an unreasonable risk of injury to
health or the environment because of a
potential hazard and a potential route of
exposure under the conditions of use,
including an unreasonable risk to
potentially exposed or susceptible
subpopulations identified as relevant by
the Administrator.’’
During the prioritization process, EPA
identifies chemical substances that are
candidates for prioritization and then
uses reasonably available information to
screen each candidate chemical
substance against certain criteria and
considerations specified in TSCA
section 6(b)(1)(A):
• The hazard and exposure potential
of the chemical substance;
• Persistence and bioaccumulation of
the chemical substance;
• Potentially exposed or susceptible
subpopulations;
• Storage near significant sources of
drinking water;
• The conditions of use or significant
changes in the conditions of use of the
chemical substance;
• The volume or significant changes
in the volume of the chemical substance
manufactured or processed; and
• Other risk-based criteria that EPA
determines to be relevant to the
designation of the chemical substance’s
priority.
Conditions of use is defined under
TSCA section 3(4) to mean ‘‘the
circumstances, as determined by the
Administrator, under which a chemical
substance is intended, known, or
reasonably foreseen to be manufactured,
processed, distributed in commerce,
used or disposed of.’’
VerDate Sep<11>2014
19:17 Apr 27, 2021
Jkt 253001
Under this process, EPA issues a
proposal to designate each chemical
substance as either a High-Priority
Substance or Low-Priority Substance
based on the results of the screening
review and other relevant information.
Following additional public comment
opportunity, EPA finalizes the
designation for each chemical
substance. Final designation of a
chemical substance as a High-Priority
Substance initiates the risk evaluation
process for that chemical substance. The
risk evaluation process has begun for
each of these 20 High-Priority
Substances. Under TSCA section 4(a)(2),
EPA may by rule, order, or consent
agreement ‘‘require the development of
new information relating to a chemical
substance or mixture if the
Administrator determines that the
information is necessary. . .to perform
a risk evaluation under section [6(b)]
. . .’’
iv. Information needs. Under TSCA
section 4(a)(2), EPA can by Test Order
require testing when there is a need for
information and all reasonably available
information has been assessed. Order
authority can be used to efficiently
obtain information to inform the TSCA
section 6 prioritization and risk
evaluation processes. Information needs
specific to each of the 20 High-Priority
Substances have been identified and
would be informed under this authority.
Additionally, collection of health and
safety data on health effects,
toxicokinetics, environmental effects,
environmental fate, physical chemical
properties, and exposure would inform
EPA activities involving these
chemicals.
2. Organohalogen Flame Retardants
i. Recommendation. The ITC is
adding a group of 24 ‘‘organohalogen
flame retardants’’ (OFRs) to the Priority
Testing List. In addition to adding these
chemicals substances to the Priority
Testing List, the ITC is also requesting
their addition to the TSCA section 8(d)
Health and Safety Data Reporting rule so
that EPA can obtain unpublished health
and safety studies on these chemical
substances.
ii. Rationale for recommendation.
CPSC requested that additive,
nonpolymeric OFRs be added to the
Priority Testing List because CPSC voted
to grant a petition to begin rulemaking
for this class of chemicals under the
Federal Hazardous Substances Act and
needs information on these OFRs for
such purposes. OFRs may be added to
consumer products to prevent or slow
combustion, but are additive, i.e., not
covalently bound to the substrate,
which can be textiles, polymers, or
PO 00000
Frm 00033
Fmt 4703
Sfmt 4703
foam. Most OFRs are semi-volatile
compounds (SVOCs), that can migrate
into air, where they bind to airborne
particles and surfaces in the home. In
addition to direct contact with OFRcontaining products, a substantial
portion of exposure is believed to occur
from exposure to household dust,
especially in children. Biomonitoring
studies and measurements of household
dust and indoor air demonstrate that
exposure to OFRs is nearly ubiquitous.
Many OFRs have been shown to cause
health effects. Health effects associated
with OFRs include carcinogenicity (e.g.,
halogenated alkyl phosphates),
developmental effects (polybrominated
diphenyl ethers, PBDEs), and
developmental neurotoxicity (i.e.,
Decabromodiphenyl ether (decaBDE)).
However, most OFRs have little or no
published human health and safety
data.
At the meeting to discuss the 74th
report of the ITC, ITC members
supported CPSC’s request to add these
OFR’s to the Priority Testing List and
had no comment as to their inclusion on
the draft Priority Testing List.
iii. Supporting information. In 2015,
CPSC was petitioned by a number of
organizations and individuals, such as
consumer groups, medical associations,
workers, and firefighter organizations, to
ban the use of all additive, nonpolymeric OFRs under the authority of
the Federal Hazardous Substances Act
in the following consumer products: (1)
Durable infant or toddler products,
children’s toys, child care articles, or
other children’s products (other than car
seats, which are under Department of
Transportation’s jurisdiction); (2)
residential upholstered furniture; (3)
mattresses and mattress pads; and (4)
the plastic casings of electronic devices
(Ref. 5).
CPSC granted the petition in 2017 and
directed staff to complete a scoping and
feasibility study in cooperation with the
National Academy of Sciences,
Engineering, and Medicine (NASEM).
The task for this project was to develop
a scientifically based scoping plan to
identify the potential health hazards
associated with additive, nonpolymeric
OFRs as a class. The NASEM Committee
published the report, ‘‘A Class
Approach to Hazard Assessment of
Organohalogen Flame Retardants’’ in
May 2019 (Ref. 6). A key conclusion of
the NASEM Committee is that OFRs
cannot be treated as a single class.
Rather, the NASEM Committee
identified 14 subclasses of OFRs, based
on chemical structure, physicochemical
properties of the chemicals, and
predicted biologic activity. The NASEM
Committee identified 161 OFRs and
E:\FR\FM\28APN1.SGM
28APN1
Federal Register / Vol. 86, No. 80 / Wednesday, April 28, 2021 / Notices
more than 1,000 analog chemicals.
CPSC staff is undertaking the risk
assessment of 14 classes of OFRs
following the recommendations of the
NASEM Committee.
iv. Information needs. Preliminary
searches show that little or no health
and safety data are available for many of
the 161 OFRs, including the OFRs being
added to the Priority Testing List in this
report and the six OFRs already on the
22417
Priority Testing List. CPSC needs health
and safety data for the OFRs; all studies
with relevant information will help fill
existing data gaps. Of special interest
are studies to help assess risks to
consumers.

SUPPLEMENTARY INFORMATION:
I. General Information
A. Does this action apply to me?
This notice is directed to the public in general. It may, however,
be of particular interest to you if you manufacture (defined by statute
to include import) and/or process chemical substances described in this
notice that are subject to the Toxic Substances Control Act (TSCA), 15
U.S.C. 2601, et seq. and you may be identified by the North American
Industrial Classification System (NAICS) codes 325 and 32411. Because
this notice is directed to the general public and other entities may
also be interested, the Agency has not attempted to describe all the
specific entities that may be interested in this action.
B. What is the Agency's authority?
TSCA section 4(e) created the TSCA ITC as an independent advisory
committee to the Administrator of the U.S. EPA. The ITC was created to
make recommendations to the EPA Administrator on prioritizing and
selecting chemicals for testing or information reporting to meet the
coordinated data needs of its member U.S. Government organizations.
Such recommendations are presented to the EPA Administrator in the form
of additions to the TSCA section 4(e) Priority Testing List. The ITC
transmits revisions to the Priority Testing List to the EPA
Administrator in ITC reports that EPA publishes in the Federal Register
for public comment as directed by TSCA.
C. What should I consider as I prepare my comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or email. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information submitted in
an electronic storage device such as a flash drive, disk or CD-ROM that
you mail to EPA, mark the outside of the device as CBI and then
identify electronically within the device the specific information that
is claimed as CBI. In addition to one complete version of the comment

V. The TSCA Interagency Testing Committee
Summary
In this 74th ITC Report, the ITC is revising the Toxic Substances
Control Act (TSCA) section 4(e) Priority Testing List by adding 15
High-Priority Substances and 24 organohalogen flame retardants and
requesting that EPA add these chemicals to the TSCA section 8(d) Health
and Safety Data Reporting rule. The ITC is also requesting that EPA add
the other five High-Priority Substances and six organohalogen flame
retardants specified in Unit III. of this report, and currently on the
Priority Testing List, to the Health and Safety Data Reporting rule.
I. Background
The ITC was established under section 4(e) of TSCA and recommends
to EPA chemical substances and mixtures to be given priority
consideration for the development of information under TSCA section
4(a). These recommendations are made in the form of a list known as the
Priority Testing List. The ITC revises the Priority Testing List as it
determines necessary and transmits such revisions to the EPA
Administrator with the ITC's rationales for the revisions. ITC Reports
are available from regulations.gov https://www.regulations.gov after
publication in the Federal Register and on EPA's website https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/interagency-testing-committee-itc-reports. The ITC produces its revisions to the
Priority Testing List with administrative and technical support from
EPA staff, ITC Members, and their U.S. Government organizations. ITC
members and staff are listed at the end of this report.
II. TSCA Section 8(d) Health and Safety Data Reporting Rule
Following receipt of the ITC's report (and the revised Priority
Testing List) by the EPA Administrator, and following the public
comment period on this report and consideration of any such comments
received, EPA's Office of Pollution Prevention and Toxics (OPPT) may
add the chemicals from the revised Priority Testing List to the TSCA
section 8(d) Health and Safety Data Reporting rule (40 CFR part 716)
(Ref. 1). The Health and Safety Data Reporting rule requires
manufacturers (including importers) of chemical substances and mixtures
added to the Health and Safety Data Reporting rule to submit lists and
copies of unpublished health and safety studies to EPA.
III. Activities During the May 2020 ITC Meeting and Revisions to the
TSCA Section 4(e) Priority Testing List: Addition of 15 High-Priority
Substances and 24 Organohalogen Flame Retardants
During the May 2020 ITC meeting, the ITC discussed the 20 High-
Priority Substances designated by EPA under TSCA section 6(b) and
information-gathering options for these substances. Five of these High-
Priority Substances were already on the Priority Testing List, added
previously by the 69th ITC Report (Ref. 2). The ITC discussed adding
the remaining 15 High-Priority Substances to the Priority Testing List
and also requesting the addition of those chemical substances to the
TSCA section 8(d) Health and Safety Data Reporting rule (40 CFR part
716) so that EPA may obtain unpublished health and safety studies on
all 20 High-Priority Substances.
During the May 2020 ITC meeting, the ITC also discussed adding a
group of organohalogen flame retardants to the Priority Testing List to
obtain unpublished health and safety studies on 30 organohalogen flame
retardants, six of which were previously added to the Priority Testing
List by the 69th ITC Report.
The 15 High-Priority Substances and 24 organohalogen flame
retardants being added to the Priority Testing List are listed in Table
1 of this unit. The remainder of the chemical substances and mixtures
on the Priority Testing List is provided in Table 2 of this unit.
The five High-Priority Substances that were already listed on the
Priority Testing List are 1,1-dichloroethane (CAS No. 75-34-3), 1,2-
dichloroethane (CAS No. 107-06-2), ethylene dibromide (CAS No. 106-93-
4), tris(2-chloroethyl) phosphate (TCEP) (CAS No. 115-96-8), and
phosphoric acid, triphenyl ester (TPP) (CAS No. 115-86-6). The ITC is
also requesting the addition of these chemical substances to the TSCA
section 8(d) Health and Safety Data Reporting rule so that EPA can
obtain unpublished health and safety studies on these substances.
The six organohalogen flame retardants that were already listed on
the Priority Testing List are bis(2-ethylhexyl) tetrabromophthalate
(CAS No. 26040-51-7), 2-ethylhexyl 2,3,4,5-tetrabromobenzoate (CAS No.
183658-27-7), phosphoric acid, 2,2-bis(chloromethyl)-1,3-propanediyl
tetrakis(2-chloroethyl) ester (CAS No. 38051-10-4), tris(2-
chloroisopropyl)phosphate (CAS No. 13674-84-5), tris(2-chloropropyl)
phosphate (CAS No. 6145-73-9), and tris(1,3-dichloro-2-propyl)
phosphate (CAS No. 13674-87-8). The ITC is also requesting the addition
of these chemical substances to the TSCA section 8(d) Health and Safety
Data Reporting rule so that EPA can obtain unpublished health and
safety studies on these substances.
Chemical Substances Added to the Priority Testing List
1. High-Priority Substances
i. Recommendation. The ITC is adding the 15 High-Priority
Substances listed in Table 1 of this report to the Priority Testing
List. The ITC is also requesting the addition of these chemical
substances to the TSCA section 8(d) Health and Safety Data Reporting
rule so that EPA can obtain to obtain unpublished health and safety
studies on health effects, physical/chemical properties, environmental
fate, environmental effects, and exposure.
ii. Rationale for recommendation. The 20 High-Priority Substances
identified in this report have been designated High-Priority under TSCA
section 6(b) because EPA has found that each of these chemical
substances may present an unreasonable risk of injury to health or the
environment under the conditions of use for that chemical substance
(Ref. 4). The development of information on these chemical substances
under TSCA section 4(a) will enable EPA to inform its risk evaluation
findings of whether any of these High-Priority Substances present an
unreasonable risk of injury to health or
[[Page 22416]]
the environment under the conditions of use for each of these chemical
substances.
iii. Supporting information. TSCA section 6 requires EPA to address
existing chemical substances with a three-stage process. The three
stages of EPA's process for ensuring there are no unreasonable risks
associated with the conditions of use of existing chemical substances
are (1) prioritization, (2) risk evaluation, and (3) risk management.
Prioritization and risk evaluation are carried out in accordance with
procedural regulations at 40 CFR part 702, subparts A and B,
respectively.
During prioritization EPA designates a chemical substance as either
High-Priority for risk evaluation, or Low-Priority for which risk
evaluation is not warranted at the time. A High-Priority Substance is
defined under TSCA section 6(b)(1)(B)(i) as ``a chemical substance that
the Administrator concludes, without consideration of costs or other
nonrisk factors, may present an unreasonable risk of injury to health
or the environment because of a potential hazard and a potential route
of exposure under the conditions of use, including an unreasonable risk
to potentially exposed or susceptible subpopulations identified as
relevant by the Administrator.''
During the prioritization process, EPA identifies chemical
substances that are candidates for prioritization and then uses
reasonably available information to screen each candidate chemical
substance against certain criteria and considerations specified in TSCA
section 6(b)(1)(A):
The hazard and exposure potential of the chemical
substance;
Persistence and bioaccumulation of the chemical substance;
Potentially exposed or susceptible subpopulations;
Storage near significant sources of drinking water;
The conditions of use or significant changes in the
conditions of use of the chemical substance;
The volume or significant changes in the volume of the
chemical substance manufactured or processed; and
Other risk-based criteria that EPA determines to be
relevant to the designation of the chemical substance's priority.
Conditions of use is defined under TSCA section 3(4) to mean ``the
circumstances, as determined by the Administrator, under which a
chemical substance is intended, known, or reasonably foreseen to be
manufactured, processed, distributed in commerce, used or disposed
of.''
Under this process, EPA issues a proposal to designate each
chemical substance as either a High-Priority Substance or Low-Priority
Substance based on the results of the screening review and other
relevant information. Following additional public comment opportunity,
EPA finalizes the designation for each chemical substance. Final
designation of a chemical substance as a High-Priority Substance
initiates the risk evaluation process for that chemical substance. The
risk evaluation process has begun for each of these 20 High-Priority
Substances. Under TSCA section 4(a)(2), EPA may by rule, order, or
consent agreement ``require the development of new information relating
to a chemical substance or mixture if the Administrator determines that
the information is necessary. . .to perform a risk evaluation under
section [6(b)] . . .''
iv. Information needs. Under TSCA section 4(a)(2), EPA can by Test
Order require testing when there is a need for information and all
reasonably available information has been assessed. Order authority can
be used to efficiently obtain information to inform the TSCA section 6
prioritization and risk evaluation processes. Information needs
specific to each of the 20 High-Priority Substances have been
identified and would be informed under this authority. Additionally,
collection of health and safety data on health effects, toxicokinetics,
environmental effects, environmental fate, physical chemical
properties, and exposure would inform EPA activities involving these
chemicals.
2. Organohalogen Flame Retardants
i. Recommendation. The ITC is adding a group of 24 ``organohalogen
flame retardants'' (OFRs) to the Priority Testing List. In addition to
adding these chemicals substances to the Priority Testing List, the ITC
is also requesting their addition to the TSCA section 8(d) Health and
Safety Data Reporting rule so that EPA can obtain unpublished health
and safety studies on these chemical substances.
ii. Rationale for recommendation. CPSC requested that additive,
nonpolymeric OFRs be added to the Priority Testing List because CPSC
voted to grant a petition to begin rulemaking for this class of
chemicals under the Federal Hazardous Substances Act and needs
information on these OFRs for such purposes. OFRs may be added to
consumer products to prevent or slow combustion, but are additive,
i.e., not covalently bound to the substrate, which can be textiles,
polymers, or foam. Most OFRs are semi-volatile compounds (SVOCs), that
can migrate into air, where they bind to airborne particles and
surfaces in the home. In addition to direct contact with OFR-containing
products, a substantial portion of exposure is believed to occur from
exposure to household dust, especially in children. Biomonitoring
studies and measurements of household dust and indoor air demonstrate
that exposure to OFRs is nearly ubiquitous.
Many OFRs have been shown to cause health effects. Health effects
associated with OFRs include carcinogenicity (e.g., halogenated alkyl
phosphates), developmental effects (polybrominated diphenyl ethers,
PBDEs), and developmental neurotoxicity (i.e., Decabromodiphenyl ether
(decaBDE)). However, most OFRs have little or no published human health
and safety data.
At the meeting to discuss the 74th report of the ITC, ITC members
supported CPSC's request to add these OFR's to the Priority Testing
List and had no comment as to their inclusion on the draft Priority
Testing List.
iii. Supporting information. In 2015, CPSC was petitioned by a
number of organizations and individuals, such as consumer groups,
medical associations, workers, and firefighter organizations, to ban
the use of all additive, non-polymeric OFRs under the authority of the
Federal Hazardous Substances Act in the following consumer products:
(1) Durable infant or toddler products, children's toys, child care
articles, or other children's products (other than car seats, which are
under Department of Transportation's jurisdiction); (2) residential
upholstered furniture; (3) mattresses and mattress pads; and (4) the
plastic casings of electronic devices (Ref. 5).
CPSC granted the petition in 2017 and directed staff to complete a
scoping and feasibility study in cooperation with the National Academy
of Sciences, Engineering, and Medicine (NASEM). The task for this
project was to develop a scientifically based scoping plan to identify
the potential health hazards associated with additive, nonpolymeric
OFRs as a class. The NASEM Committee published the report, ``A Class
Approach to Hazard Assessment of Organohalogen Flame Retardants'' in
May 2019 (Ref. 6). A key conclusion of the NASEM Committee is that OFRs
cannot be treated as a single class. Rather, the NASEM Committee
identified 14 subclasses of OFRs, based on chemical structure,
physicochemical properties of the chemicals, and predicted biologic
activity. The NASEM Committee identified 161 OFRs and
[[Page 22417]]
more than 1,000 analog chemicals. CPSC staff is undertaking the risk
assessment of 14 classes of OFRs following the recommendations of the
NASEM Committee.
iv. Information needs. Preliminary searches show that little or no
health and safety data are available for many of the 161 OFRs,
including the OFRs being added to the Priority Testing List in this
report and the six OFRs already on the Priority Testing List. CPSC
needs health and safety data for the OFRs; all studies with relevant
information will help fill existing data gaps. Of special interest are
studies to help assess risks to consumers.
