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 
that includes information claimed as CBI, a copy of the comment that 
does not contain the information claimed as CBI must be submitted for 
inclusion in the public docket. Information so marked will not be 
disclosed except in accordance with procedures set forth in 40 CFR part 
2.
    2. Tips for preparing your comments. When preparing and submitting 
your comments, see the commenting tips at http://www.epa.gov/dockets/comments.html.

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 http://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.
