Significant New Use Rules on Certain Chemical Substances (19-3.F)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing significant new use rules (SNURs) under the 
Toxic Substances Control Act (TSCA) for 31 chemical substances which 
were the subject of premanufacture notices (PMNs). Eight of these 
chemical substances are subject to TSCA Orders issued by EPA and the 
remaining 23 of these chemical substances received a ``not likely to 
present an unreasonable risk'' determination. This action would require 
persons who intend to manufacture (defined by statute to include 
import) or process any of these 31 chemical substances for an activity 
that is proposed as a significant new use to notify EPA at least 90 
days before commencing that activity. Persons may not commence 
manufacture or processing for the significant new use until EPA has 
conducted a review of the notice, made an appropriate determination on 
the notice, and has taken such actions as are required by that 
determination.

DATES: Comments must be received on or before November 12, 2019.

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you manufacture, 
process, or use the chemical substances contained in this proposed 
rule. The following list of North American Industrial Classification 
System (NAICS) codes is not intended to be exhaustive, but rather 
provides a guide to help readers determine whether this document 
applies to them. Potentially affected entities may include:
     Manufacturers or processors of one or more subject 
chemical substances (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries.
    This action may also affect certain entities through pre-existing 
import certification and export notification rules under TSCA. Chemical 
importers are subject to the TSCA section 13 (15 U.S.C. 2612) import 
certification requirements promulgated at 19 CFR

[[Page 54817]]

12.118 through 12.127 and 19 CFR 127.28. Chemical importers must 
certify that the shipment of the chemical substance complies with all 
applicable rules and orders under TSCA. Importers of chemicals subject 
to final SNURs must certify their compliance with the SNUR 
requirements. The EPA policy in support of import certification appears 
at 40 CFR part 707, subpart B. In addition, any persons who export or 
intend to export a chemical substance that is the subject of this 
proposed rule on or after November 12, 2019 are subject to the export 
notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see 
40 CFR 721.20), and must comply with the export notification 
requirements in 40 CFR part 707, subpart D.

B. 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 in a disk or 
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as 
CBI and then identify electronically within the disk or CD-ROM 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.

II. Background

A. What action is the Agency taking?

    EPA is proposing these SNURs under TSCA section 5(a)(2) for 
chemical substances that were the subject of PMNs. These proposed SNURs 
would require persons to notify EPA at least 90 days before commencing 
the manufacture or processing of a chemical substance for any activity 
proposed as a significant new use. Receipt of such notices would allow 
EPA to assess risks and, if appropriate, to regulate the significant 
new use before it may occur. Additional background regarding SNURs is 
more fully set out in the preamble to EPA's first direct final SNUR 
published in the Federal Register issue of April 24, 1990 (55 FR 17376) 
(FRL-3658-5). Consult that preamble for further general information on 
the objectives, rationale, and procedures for SNURs and on the basis 
for significant new use designations, including provisions for 
developing test data.

B. What is the Agency's authority for taking this action?

    Section 5(a)(2) of TSCA (15 U.S.C. 2604(a)(2)) authorizes EPA to 
determine that a use of a chemical substance is a ``significant new 
use.'' EPA must make this determination by rule after considering all 
relevant factors, including the four bulleted TSCA section 5(a)(2) 
factors listed in Unit III.

C. Applicability of General Provisions

    General provisions for SNURs appear in 40 CFR part 721, subpart A. 
These provisions describe persons subject to the proposed rule, 
recordkeeping requirements, and exemptions to reporting requirements, 
and applicability of the rule to uses occurring before the effective 
date of the rule. Provisions relating to user fees appear at 40 CFR 
part 700. Pursuant to 40 CFR 721.1(c), persons subject to SNURs must 
comply with the same SNUN requirements and EPA regulatory procedures as 
submitters of PMNs under TSCA section 5(a)(1)(A) (15 U.S.C. 
2604(a)(1)(A)). In particular, these requirements include the 
information submission requirements of TSCA section 5(b) and 5(d)(1) 
(15 U.S.C. 2604(b) and 2604(d)(1)), the exemptions authorized by TSCA 
section 5(h)(1), (h)(2), (h)(3), and (h)(5), and the regulations at 40 
CFR part 720. Once EPA receives a SNUN, EPA must either determine that 
the use is not likely to present an unreasonable risk of injury under 
the conditions of use for the chemical substance or take such 
regulatory action as is associated with an alternative determination 
before the manufacture or processing for the significant new use can 
commence. In the case of a determination other than not likely to 
present unreasonable risk, the applicable review period must also 
expire before manufacturing or processing for the new use may commence. 
If EPA determines that the use is not likely to present an unreasonable 
risk, EPA is required under TSCA section 5(g) to make public, and 
submit for publication in the Federal Register, a statement of EPA's 
findings.

III. Significant New Use Determination

    TSCA section 5(a)(2) states that EPA's determination that a use of 
a chemical substance is a significant new use must be made after 
consideration of all relevant factors, including:
     The projected volume of manufacturing and processing of a 
chemical substance.
     The extent to which a use changes the type or form of 
exposure of human beings or the environment to a chemical substance.
     The extent to which a use increases the magnitude and 
duration of exposure of human beings or the environment to a chemical 
substance.
     The reasonably anticipated manner and methods of 
manufacturing, processing, distribution in commerce, and disposal of a 
chemical substance.
    In determining significant new uses for the 31 chemical substances 
that are the subject of these SNURs, EPA considered relevant 
information about the toxicity of the chemical substances and potential 
human exposures and environmental releases that may be associated with 
the substances, in addition to the factors in TSCA section 5(a)(2). 
Consistent with TSCA section 5(f)(4), for the eight chemical substances 
subject to an order under TSCA section 5(e), EPA is proposing to 
identify any use not conforming to the restrictions of the order as a 
significant new use. For the 23 chemical substances that EPA has 
determined ``not likely'' to present an unreasonable risk under the 
conditions of use, EPA is proposing to identify other circumstances 
that, while not reasonably foreseen, would warrant further EPA review 
before manufacture or processing for such a use is commenced.

IV. Substances Subject to This Proposed Rule

    EPA is proposing significant new use and recordkeeping requirements 
for 31 chemical substances in 40 CFR part 721, subpart E. In this unit, 
EPA provides the following information for each chemical substance:
     PMN number.
     Chemical name (generic name, if the specific name is 
claimed as CBI).
     Chemical Abstracts Service (CAS) Registry number (if 
assigned for non-confidential chemical identities).
     Basis for the SNUR or basis for the TSCA section 5(e) 
Order.
     Potentially Useful Information. This is information 
identified by EPA that would help characterize the potential health 
and/or environmental effects of the chemical substance in support of a 
request by the PMN submitter to modify the Order, or if a manufacturer 
or processor is considering submitting a SNUN for a significant new use 
designated by the SNUR.

[[Page 54818]]

     CFR citation assigned in the regulatory text section of 
the proposed rule. The regulatory text section of each proposed rule 
specifies the activities that would be designated as significant new 
uses. Certain new uses, including exceedance of production volume 
limits (i.e., limits on manufacture volume) and other uses designated 
in this proposed rule, may be claimed as CBI.
    These proposed rules include 8 PMN substances that are subject to 
orders issued under TSCA section 5(e)(1)(A), as required by the 
determinations made under TSCA section 5(a)(3)(B). Those TSCA section 
5(e) Orders require protective measures to limit exposures or otherwise 
mitigate the potential unreasonable risk. The proposed SNURs would 
identify as significant new uses any manufacturing, processing, use, 
distribution in commerce, or disposal that does not conform to the 
restrictions imposed by the underlying TSCA section 5(e) Orders, 
consistent with TSCA section 5(f)(4).
    These proposed rules also include 23 PMN substances that received 
``not likely to present an unreasonable risk'' determination in TSCA 
section 5(a)(3)(c). However, during the course of these reviews, EPA 
identified concerns for certain health and/or environmental risks if 
the chemicals were not used following the limitations identified by the 
submitters in the notices. EPA did not deem such uses as reasonably 
foreseen in the TSCA section 5(a)(3)(C) determinations. The proposed 
SNURs would identify as significant new uses any manufacturing, 
processing, use, distribution in commerce, or disposal that does not 
conform to those same limitations.
    The chemicals subject to these proposed SNURs are as follows:

PMN Numbers: P-16-151, P-16-152, P-16-153, P-16-154, and P-16-155

    Chemical names: Perfluoropolyether halide (generic) (P-16-151), 
Perfluoropolyether aryl (generic) (P-16-152), Substituted aryl-
perfluoropolyether (generic) (P-16-153), Sulfonated perfluoropolyether 
aromatic transition metal salt (generic) (P-16-154), and Sulfonated 
perfluoropolyether aryl alkali metal salt (generic) (P-16-155).
    CAS numbers: Not available.
    Effective date of TSCA section 5(e) Order: April 30, 2019.
    Basis for TSCA section 5(e) Order: The PMNs state that the generic 
(non-confidential) use of the substances P-16-151 and P-16-152 will be 
as intermediates and P-16-153, P-16-154, P-16-155 will be as lubricant 
additives. Based on the physical/chemical properties of the PMN 
substances (as described in the New Chemical Program's PBT category at 
64 FR 60194; November 4, 1999) and test data on structurally similar 
substances, the PMN substances are potentially persistent, 
bioaccumulative, and toxic (PBT) chemicals. EPA estimates that the PMN 
substances will persist in the environment more than 2 months and 
estimates a bioaccumulation factor of greater than or equal to 1,000. 
Based on results of testing on analogous small fluorinated polyether 
substances, EPA has identified concerns for the possible degradation 
products of the PMN substances for liver toxicity, kidney effects, 
hematology and clinical chemistry changes, pancreatic and testicular 
cell tumor formation, and reproductive and developmental effects. Based 
on estimated ecotoxicity values for the possible degradation products, 
EPA predicts toxicity to aquatic organisms may occur at concentrations 
that exceed 153 parts per billion (ppb). The TSCA section 5(e) Order 
was issued under TSCA sections 5(a)(3)(B)(i) and 5(e)(1)(A)(i), based 
on a finding that the available information is insufficient to permit a 
reasoned evaluation of the human health and environmental effects of 
the PMN substances. The TSCA section 5(e) Order was also issued under 
TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a 
finding that in the absence of sufficient information to permit a 
reasoned evaluation, the substances may present an unreasonable risk of 
injury to human health and the environment. To protect against these 
risks, the TSCA section 5(e) Order requires:
    1. Submission to EPA of certain fate testing within one year after 
the Notice of Commencement of the PMN P-16-155;
    2. Establishment and use of a hazard communication program, 
including environmental hazard precautionary statements on each label 
and in the Safety Data Sheet (SDS);
    3. Dispose of the PMN substances only with Hazardous Waste, High 
Temperature Incineration with a control efficiency of 99.99% efficiency 
or greater;
    4. No release of the PMN substances to surface waters;
    5. Manufacture the PMN substances only for the confidential uses 
specified in the PMNs; and
    6. No manufacture beyond the annual production volumes specified in 
the TSCA section 5(e) Order.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the TSCA section 5(e) Order, or if a 
manufacturer or processor is considering submitting a SNUN for a 
significant new use that would be designated by this SNUR. The 
submitter has agreed not to manufacture (including import) the P-16-155 
substance beyond one year after the Notice of Commencement without 
performing an indirect photolysis screening test (OCSPP Test Guideline 
835.5270). EPA has also determined that the results of hydrolysis 
testing, photodegradation in soil, chronic aquatic toxicity, and 
reproductive toxicity testing would help EPA determine the potential 
human and environmental effects of the PMN substances. Although the 
TSCA section 5(e) Order does not require these tests, the TSCA section 
5(e) Order's restrictions remain in effect until the TSCA section 5(e) 
Order is modified or revoked by EPA based on submission of this or 
other relevant information.

152); 40 CFR 721.11348 (P-16-153); 40 CFR 721.11349 (P-16-154) and 40 
CFR 721.11350 (P-16-155).

PMN Number: P-16-225

    Chemical names: Cyclohexanol, 4-ethylidene-2-propoxy- (P-16-225, 
chemical A) and Cyclohexanol, 5-ethylidene-2-propoxy- (P-16-225, 
chemical B).
    CAS numbers: 1631145-48-6 (P-16-225, chemical A) and 1631145-49-7 
(P-16-225, chemical B).
    Basis for action: The PMN states that the use of the substance will 
be as a fragrance ingredient, being blended (mixed) with other 
fragrance ingredients to make fragrance oils that will be sold to 
industrial and commercial customers for their incorporation into soaps, 
detergents, cleaners, air fresheners, candles and other similar 
industrial, household and consumer products. Based on the physical/
chemical properties of the PMN substances, test data on the PMN 
substances, and Structure Analysis Relationships (SAR) analysis of test 
data on analogous substances, EPA has identified concerns for systemic 
toxicity, and aquatic toxicity at surface water concentrations 
exceeding 300 ppb, if the chemical substance is not used following the 
limitations noted. The conditions of use of the PMN substances as 
described in the PMN include the following protective measures:

[[Page 54819]]

    1. No domestic manufacture of the PMN substances (i.e., import 
only);
    2. No import of the PMN substances at more than 10,000 kg annual 
production volume;
    3. No use of the PMN substances other than for the fragrance use 
stated in the PMN submission; and
    4. No processing of the PMN substances to greater than 10% in 
compounded fragrance oil formulation.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health and 
environmental effects of the PMN substances in support of a request by 
the PMN submitter to modify the TSCA section 5(e) Order, or if a 
manufacturer or processor is considering submitting a SNUN for a 
significant new use that would be designated by this proposed SNUR. EPA 
has determined that the results of absorption testing and aquatic 
toxicity testing would help characterize the potential health and 
environmental effects of the PMN substances.
    CFR citation: 40 CFR 721.11351 (P-16-225, chemical A) and 40 CFR 
721.11352 (P-16-225, chemical B).

PMN Number: P-16-314

    Chemical Name: Ethanone, 1-(5-propyl-1,3-benzodioxol-2-yl)-.
    CAS Number: 1370699-98-1.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as part of a fragrance 
formula. Based on test data on the new chemical substance, the 
estimated physical/chemical properties of the PMN, and SAR analysis on 
analogous neutral organics, EPA has identified concerns for liver 
toxicity for the intact new chemical substance, oncogenicity for the 
ketone/aldehyde hydrolysis product(s) that may be formed under the 
acidic conditions in the stomach, and aquatic toxicity if the chemical 
substance is not used following the limitations noted. The conditions 
of use of the PMN substance as described in the PMN include the 
following protective measures:
    1. No domestic manufacture of the PMN substance (i.e., import 
only);
    2. Less than 10% of the PMN substance in any formulation from 
processing; and
    3. No manufacture (including import) beyond an annual production 
volume of 10,000 kilograms per year.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health and 
environmental effects of the PMN substance if a manufacturer or 
processor is considering submitting a SNUN for a significant new use 
that would be designated by this proposed SNUR. EPA has determined that 
the results of absorption testing and aquatic toxicity testing would 
help characterize the potential health and environmental effects of the 
PMN substance.
    CFR Citation: 40 CFR 721.11353.

PMN Number: P-16-429

    Chemical Name: Endcapped polysiloxane (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as a universal tint 
paste resin having high solids. Based on the estimated physical/
chemical properties of the PMN substance, structural information, and 
information on analogous alkoxysilanes, EPA has identified lung effects 
and irritation to the eye, skin, lung, and mucous membranes if the 
chemical substance is not used following the limitation noted. The 
condition of use of the PMN substance as described in the PMN includes 
the following protective measure:
     Use of the PMN substance only for the confidential use 
specified in the PMN.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of this protective measure.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health 
effects of the PMN substance if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this proposed SNUR. EPA has determined that the results 
of pulmonary effects and skin irritation testing would help 
characterize the potential health effects of the PMN substance.
    CFR Citation: 40 CFR 721.11354.

PMN Number: P-16-470

    Chemical Name: 2,7-Nonadien-4-ol, 4,8-dimethyl-.
    CAS Number: 103983-77-3.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as part of a fragrance 
formula. Based on the estimated physical/chemical properties of the PMN 
substance and available data on the new chemical substance, EPA has 
identified concerns for skin irritation, eye irritation, liver and 
thyroid toxicity, and aquatic toxicity if the chemical substance is not 
used following the limitations noted. The conditions of use of the PMN 
substance as described in the PMN include the following protective 
measure:
     No release of the PMN substance from manufacturing or 
processing resulting in surface water concentrations that exceed 113 
ppb;
    The proposed SNUR would designate as a ``significant new use'' the 
absence of this protective measure.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health and 
environmental effects of the PMN substance if a manufacturer or 
processor is considering submitting a SNUN for a significant new use 
that would be designated by this proposed SNUR. EPA has determined that 
the results of specific organ toxicity and aquatic toxicity testing 
would help characterize the potential health and environmental effects 
of the PMN substance.
    CFR Citation: 40 CFR 721.11355.

PMN Number: P-17-108

    Chemical Name: Carbonodithioic acid, O-[2-[(dithiocarboxy)amino]-2-
methylpropyl] ester, sodium salt (1:2).
    CAS Number: 1947332-67-3.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be for use in ore 
processing. Based on the estimated physical/chemical properties of the 
PMN substance, available PMN data, comparison with structurally 
analogous chemical substances, and SAR analysis of test data on 
analogous dithiocarbamates, EPA has identified concerns for irritation 
and corrosion to all tissues, developmental and neurological effects, 
and aquatic toxicity if the chemical substance is not used following 
the limitations noted. The conditions of use of the PMN substance as 
described in the PMN include the following protective measure:
     No release of the PMN substance resulting in surface water 
concentrations exceeding 2 ppb.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health and 
environmental effects of the PMN substance if a manufacturer or 
processor is considering submitting a SNUN for a significant new use 
that would be designated by this proposed SNUR. EPA has determined that 
the results of reproductive/developmental toxicity, neurotoxicity, skin 
irritation/

[[Page 54820]]

corrosion, and toxicokinetics and chronic aquatic ecotoxicity testing 
would help characterize the potential health and environmental effects 
of the PMN substance.

limitations noted. The condition of use of the PMN substance as 
described in the PMN includes the following protective measures:
     No processing of the substance to a concentration greater 
than 5% by weight in the final formulated product, for any use; and
     No consumer use.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health 
effects of the PMN substance if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this proposed SNUR. EPA has determined that pulmonary 
effects testing would help characterize the potential health effects of 
the PMN substance.
    CFR Citation: 40 CFR 721.11357.

PMN Number: P-18-91

    Chemical Name: Vegetable oil, polymers with diethylene glycol- and 
polyol- and polyethylene glycol-depolymd. poly(ethylene terephthalate) 
waste plastics and arylcarboxylic acid anhydride (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the use of the PMN substance 
will be as a chemical intermediate (polyol) for use in the manufacture 
of polyurethane polymers. Based on the estimated physical/chemical 
properties of the PMN substance, comparison with structurally analogous 
chemical substances, test data on analogous substances, and SAR 
analysis on esters, EPA has identified concerns for lung effects, 
irritation to eye, mucous membranes and lung, anesthetization of the 
eye, developmental, renal and bladder toxicity, kidney toxicity, and 
renal cancer if the chemical substance is not used following the 
limitations noted. The condition of use of the PMN substance as 
described in the PMN includes the following protective measure:

of in vitro skin irritation and eye damage testing using human derived 
cells would help characterize the potential health effects of the PMN 
substance.
    CFR Citation: 40 CFR 721.11358.

PMN Number: P-18-120

    Chemical Name: 1H-Pyrrole-2,5-dione, 1,1'-C36-alkylenebis-.
    CAS Number: 1911605-95-2.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be as an adhesive 
component. Based on the available data for the new chemical substance, 
estimated physical/chemical properties of the PMN substance, and 
comparison with structurally analogous chemical substances, EPA has 
identified concerns for developmental toxicity and sensitization if the 
chemical substance is not used following the limitation noted. The 
condition of use of the PMN substance as described in the PMN includes 
the following protective measure:
     No manufacturing, processing, or use of the substance that 
results in inhalation exposures.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of this protective measure.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful to characterize the health 
effects of the PMN substance if a manufacturer or processor is 
considering submitting a SNUN for a significant new use that would be 
designated by this proposed SNUR. EPA has determined that the results 
of developmental toxicity and sensitization testing would help 
characterize the potential health effects of the PMN substance.

PMN Number: P-18-129

    Chemical name: Benzenepropanal, .alpha.,.alpha.,3-trimethyl-.
    CAS number: 107737-97-3.
    Effective date of TSCA section 5(e) Order: April 30, 2019.
    Basis for TSCA section 5(e) Order: The PMN states that the generic 
(non-confidential) use of the substance will be as an intermediate used 
for chemical production. Based on test data on the PMN substance and 
analogue data, EPA has identified concerns for sensitization and 
developmental toxicity. In addition, based on SAR analysis of test data 
on analogous neutral organics, EPA predicts toxicity to aquatic 
organisms may occur at concentrations greater than 99 ppb. The TSCA 
section 5(e) Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 
5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient 
information to permit a reasoned evaluation, the substance may present 
an unreasonable risk of injury to human health and the environment. To 
protect against these risks, the TSCA section 5(e) Order requires:
     No manufacture (including import) of the PMN substance 
beyond the confidential annual production volume specified in the TSCA 
section 5(e) Order.
    The proposed SNUR would designate as a ``significant new use'' the 
absence of this protective measure.
    Potentially useful information: EPA has determined that certain 
information may be potentially useful in support of a request by the 
PMN submitter to modify the TSCA section 5(e) Order, or if a 
manufacturer or processor is considering submitting a SNUN for a 
significant new use that would be designated by this SNUR. EPA has 
determined that the results of biodegradability, chronic aquatic 
toxicity, and reproductive toxicity testing would help EPA determine 
the potential human and environmental effects of the PMN substance. 
Although the TSCA section 5(e) Order does not require this information, 
the TSCA section 5(e) Order's restrictions remain in effect until the 
TSCA section 5(e) Order is modified or revoked by EPA based on 
submission of this or other relevant information.

[[Page 54821]]

    Effective date of TSCA section 5(e) Order: May 3, 2019.
    Basis for TSCA section 5(e) Order: The PMN states that substance 
will be used in heat transfer, heat storage, thermal emission, and 
general temperature management in heat-generating systems such as 
electronics, to improve mechanical properties or electrical 
conductivities of other materials or products, and for light absorption 
properties. EPA has identified concerns for pulmonary toxicity based on 
carbon nanotube analogues. EPA has also identified concerns for aquatic 
toxicity when the substance is at low concentrations and in the 
presence of natural organic matter. The TSCA section 5(e) Order was 
issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation, the substance may present an unreasonable 
risk of injury to human health and the environment. To protect against 
these risks, the TSCA section 5(e) Order requires:
    1. Use of personal protective equipment by workers to prevent 
dermal exposure where there is potential dermal exposure;
    2. Use of a National Institute of Occupational Safety and Health 
(NIOSH) certified respirators with an Assigned Protection Factor (APF) 
of at least 50 workers to prevent inhalation exposure where there is 
potential inhalation exposure;
    3. Refrain from using the PMN in applications that generates a 
dust, vapor, mist, or aerosol, unless such application method occurs in 
an enclosed process;
    4. Process and use of the PMN substance only as described in the 
PMN;
    5. No release of the PMN substance to surface waters; and
    6. Disposal only by incineration or landfill.
    The proposed SNUR designates as a ``significant new use'' the 
absence of these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the human health and environmental effects of the PMN 
substance may be potentially useful in support of a request by the PMN 
submitter to modify the TSCA section 5(e) Order, or if a manufacturer 
or processor is considering submitting a SNUN for a significant new use 
that would be designated by this SNUR. EPA has determined that the 
results of pulmonary toxicity and chronic aquatic toxicity testing 
would help EPA determine the potential human and environmental effects 
of the PMN substance. Although the TSCA section 5(e) Order does not 
require this information, the TSCA section 5(e) Order's restrictions 
remain in effect until the TSCA section 5(e) Order is modified or 
revoked by EPA based on submission of this or other relevant 
information.

    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: March 29, 2019.
    Basis for TSCA section 5(e) Order: The PMN states that the use of 
the PMN substance will be as an adhesive for automotive parts. EPA 
identified concerns for reproductive/developmental toxicity, 
mutagenicity, and carcinogenicity for the low molecular weight 
components based on the epoxides chemical category and submitted test 
data. EPA also identified concerns for skin and lung sensitization and 
systematic toxicity based on the epoxide moieties. In addition, based 
on analysis of test data on the PMN substance and SAR analysis on 
analogous thiols/mercaptans, polyepoxides, and monoepoxides, EPA 
predicts chronic toxicity to aquatic organisms may occur at 
concentrations greater than 1 ppb. The TSCA section 5(e) Order was 
issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), 
based on a finding that in the absence of sufficient information to 
permit a reasoned evaluation the substance may present an unreasonable 
risk of injury to human health and the environment. To protect against 
these risks, the TSCA section 5(e) Order requires:
    1. Use of personal protective equipment where there is a potential 
for dermal exposure;
    2. Refraining from manufacture, processing or use of the PMN 
substance in a manner that would result in inhalation exposure;
    3. No release of the PMN substance to surface waters exceeding 1 
ppb; and
    4. Establishment and use of a hazard communication program, 
including human health precautionary statements on each label and in 
the SDS.
    The SNUR designates as a ``significant new use'' the absence of 
these protective measures.
    Potentially useful information: EPA has determined that certain 
information about the health and environmental effects of the PMN 
substance may be potentially useful in support of a request by the PMN

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances 
that are subject to these proposed SNURs, EPA concluded that for 8 
chemical substances regulation was warranted under TSCA section 5(e), 
pending the development of information sufficient to make reasoned 
evaluations of the health or environmental effects of the chemical 
substances. The basis for such findings is outlined in Unit IV. Based 
on these findings, TSCA section 5(e) Orders requiring the use of 
appropriate exposure controls were negotiated with the PMN submitters. 
As a general matter, EPA believes it is necessary to follow TSCA 
section 5(e) Orders with a SNUR that identifies the absence of those 
protective measures as Significant New Uses to ensure that all 
manufacturers and processors--not just the original submitter--are held 
to the same standard.
    During review of the other 23 chemical substances that are the 
subject of these SNURs and as further discussed in Unit IV, EPA 
identified certain circumstances different from the intended conditions 
of use that raised potential risk concerns. EPA determined that 
deviations from the protective measures identified in the submissions 
could result in changes in the type or form of exposure to the chemical 
substances and/or increased exposures to the chemical substances and/or 
changes in the reasonably anticipated manner and methods of 
manufacturing, processing, distribution in commerce, and disposal of 
the chemical substances, and therefore warranted SNURs. The SNURs would 
identify as significant new uses any manufacturing, processing, use, 
distribution in commerce, or disposal that does not conform to the 
protective measures in the submission.

B. Objectives

    EPA is proposing these SNURs for specific chemical substances which

[[Page 54824]]

have undergone premanufacture review because the Agency wants:
     To receive notice of any person's intent to manufacture or 
process a listed chemical substance for the described significant new 
use before that activity begins.
     To review and evaluate data submitted in a SNUN before the 
notice submitter begins manufacturing or processing a listed chemical 
substance for the described significant new use.
     To either determine that the prospective manufacture or 
processing is not likely to present an unreasonable risk, or to take 
necessary regulatory action associated with any other determination, 
before the described significant new use of the chemical substance 
occurs.
    Issuance of a SNUR for a chemical substance does not signify that 
the chemical substance is listed on the TSCA Chemical Substance 
Inventory (TSCA Inventory). Guidance on how to determine if a chemical 
substance is on the TSCA Inventory is available on the internet at 
http://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/index.html.

VI. Applicability of the Proposed Significant New Use Designation

    To establish a significant new use, EPA must determine that the use 
is not ongoing. The chemical substances subject to this proposed rule 
have undergone premanufacture review. In cases where EPA has not 
received a notice of commencement (NOC) and the chemical substance has 
not been added to the TSCA Inventory, no person may commence such 
activities without first submitting a PMN. Therefore, for chemical 
substances for which an NOC has not been submitted EPA concludes that 
the designated significant new uses are not ongoing.
    When chemical substances identified in this proposed rule are added 
to the TSCA Inventory, EPA recognizes that, before the rule is 
effective, other persons might engage in a use that has been identified 
as a significant new use. However, TSCA section 5(e) Orders have been 
issued for 8 of the 31 chemical substances, and the PMN submitters are 
prohibited by the TSCA section 5(e) Orders from undertaking activities 
which would be designated as significant new uses. The identities of 25 
of the 31 chemical substances subject to this proposed rule have been 
claimed as confidential (per 40 CFR 720.85) for a chemical substance 
covered by this action. Based on this, the Agency believes that it is 
highly unlikely that any of the significant new uses described in the 
regulatory text of this proposed rule are ongoing.
    Therefore, EPA designates October 11, 2019 as the cutoff date for 
determining whether the new use is ongoing. The objective of EPA's 
approach is to ensure that a person cannot defeat a SNUR by initiating 
a significant new use before the effective date of the final rule.
    Persons who begin commercial manufacture or processing of the 
chemical substances for a significant new use identified as of that 
date would have to cease any such activity upon the effective date of 
the final rule. To resume their activities, these persons would have to 
first comply with all applicable SNUR notification requirements and 
wait until EPA has conducted a review of the notice, made an 
appropriate determination on the notice, and has taken such actions as 
are required with that determination.

VII. Development and Submission of Information

    EPA recognizes that TSCA section 5 does not require developing any 
particular new information (e.g., generating test data) before 
submission of a SNUN. There is an exception: Development of test data 
is required where the chemical substance subject to the SNUR is also 
subject to a rule, order or consent agreement under TSCA section 4 (see 
TSCA section 5(b)(1)).
    In the absence of a TSCA section 4 test rule covering the chemical 
substance, persons are required only to submit information in their 
possession or control and to describe any other information known to or 
reasonably ascertainable by them (see 40 CFR 720.50). However, upon 
review of PMNs and SNUNs, the Agency has the authority to require 
appropriate testing. Unit IV. lists potentially useful information 
identified by EPA that would help characterize the potential health 
and/or environmental effects of the PMN/SNUN substance for all the 
listed SNURs. EPA recognizes that the 2016 Lautenberg Amendments have 
led to modifications in our approach to testing requirements, including 
an increased consideration of alternatives to vertebrate testing. 
Descriptions of tests/information needs are provided for informational 
purposes only and EPA strongly encourages persons, before performing 
any testing, to consult with the Agency pertaining to protocol 
selection. Pursuant to TSCA section 4(h), which pertains to reduction 
of testing in vertebrate animals, EPA encourages consultation with the 
Agency on the use of alternative test methods and strategies (also 
called New Approach Methodologies, or NAMs), if available, to generate 
the potentially useful information. EPA encourages dialogue with Agency 
representatives to help determine how best the submitter can meet both 
the data needs and the objective of TSCA section 4(h). To access the

    The potentially useful information listed in Unit IV. may not be 
the only means of addressing the potential risks of the chemical 
substance. EPA recommends that potential SNUN submitters contact EPA 
early enough so that they will be able to conduct the appropriate 
tests.
    SNUN submitters should be aware that EPA will be better able to 
evaluate SNUNs which provide detailed information on the following:
     Human exposure and environmental release that may result 
from the significant new use of the chemical substances.

VIII. SNUN Submissions

    According to 40 CFR 721.1(c), persons submitting a SNUN must comply 
with the same notification requirements and EPA regulatory procedures 
as persons submitting a PMN, including submission of test data on 
health and environmental effects as described in 40 CFR 720.50. SNUNs 
must be submitted on EPA Form No. 7710-25, generated using e-PMN 
software, and submitted to the Agency in accordance with the procedures 
set forth in 40 CFR 720.40 and 721.25. E-PMN software is available 
electronically at http://www.epa.gov/opptintr/newchems.

IX. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers and processors of the chemical 
substances subject to this proposed rule. EPA's complete economic 
analysis is available in the docket identified for this rulemaking 
under ADDRESSES.

X. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.epa.gov/laws-regulations-and-executive-orders.

[[Page 54825]]

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulations and Regulatory Review

    This proposed rule would establish SNURs for several new chemical 
substances that were the subject of PMNs and TSCA section 5(e) Orders. 
The Office of Management and Budget (OMB) has exempted these types of 
actions from review under Executive Orders 12866 (58 FR 51735, October 
4, 1993) and 13563 (76 FR 3821, January 21, 2011).

B. Paperwork Reduction Act (PRA)

    According to PRA (44 U.S.C. 3501 et seq.), an agency may not 
conduct or sponsor, and a person is not required to respond to a 
collection of information that requires OMB approval under PRA, unless 
it has been approved by OMB and displays a currently valid OMB control 
number. The OMB control numbers for EPA's regulations in title 40 of 
the CFR, after appearing in the Federal Register, are listed in 40 CFR 
part 9, and included on the related collection instrument or form, if 
applicable.
    The information collection requirements related to this proposed 
rule have already been approved by OMB pursuant to PRA under OMB 
control number 2070-0012 (EPA ICR No. 574). This action does not impose 
any burden requiring additional OMB approval. If an entity were to 
submit a SNUN to the Agency, the annual burden is estimated to average 
between 30 and 170 hours per response. This burden estimate includes 
the time needed to review instructions, search existing data sources, 
gather and maintain the data needed, and complete, review, and submit 
the required SNUN.
    Send any comments about the accuracy of the burden estimate, and 
any suggested methods for minimizing respondent burden, including the 
use of automated collection techniques, to the Director, Regulatory 
Support Division, Office of Mission Support (2822T), Environmental 
Protection Agency, 1200 Pennsylvania Ave. NW, Washington, DC 20460-
0001. Please remember to include the OMB control number in any 
correspondence, but do not submit any completed forms to this address.

C. Regulatory Flexibility Act (RFA)

    Pursuant to section 605(b) of the RFA (5 U.S.C. 601 et seq.), the 
Agency hereby certifies that promulgation of this proposed SNUR would 
not have a significant adverse economic impact on a substantial number 
of small entities. The requirement to submit a SNUN applies to any 
person (including small or large entities) who intends to engage in any 
activity described in the final rule as a ``significant new use.'' 
Because these uses are ``new,'' based on all information currently 
available to EPA, it appears that no small or large entities presently 
engage in such activities. A SNUR requires that any person who intends 
to engage in such activity in the future must first notify EPA by 
submitting a SNUN. Although some small entities may decide to pursue a 
significant new use in the future, EPA cannot presently determine how 
many, if any, there may be. However, EPA's experience to date is that, 
in response to the promulgation of SNURs covering over 1,000 chemicals, 
the Agency receives only a small number of notices per year. For 
example, the number of SNUNs received was seven in Federal fiscal year 
(FY) 2013, 13 in FY2014, six in FY2015, 10 in FY2016, 14 in FY2017, and 
18 in FY2018 and only a fraction of these were from small businesses. 
In addition, the Agency currently offers relief to qualifying small 
businesses by reducing the SNUN submission fee from $16,000 to $2,800. 
This lower fee reduces the total reporting and recordkeeping of cost of 
submitting a SNUN to about $10,116 for qualifying small firms. 
Therefore, the potential economic impacts of complying with this 
proposed SNUR are not expected to be significant or adversely impact a 
substantial number of small entities. In a SNUR that published in the 
Federal Register of June 2, 1997 (62 FR 29684) (FRL-5597-1), the Agency 
presented its general determination that final SNURs are not expected 
to have a significant economic impact on a substantial number of small 
entities, which was provided to the Chief Counsel for Advocacy of the 
Small Business Administration.

D. Unfunded Mandates Reform Act (UMRA)

    Based on EPA's experience with proposing and finalizing SNURs, 
State, local, and Tribal governments have not been impacted by these 
rulemakings, and EPA does not have any reasons to believe that any 
State, local, or Tribal government will be impacted by this action. As 
such, EPA has determined that this proposed rule would not impose any 
enforceable duty, contain any unfunded mandate, or otherwise have any 
effect on small governments subject to the requirements of UMRA 
sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

E. Executive Order 13132: Federalism

    This action would not have a substantial direct effect on States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government, as specified in Executive Order 13132 (64 FR 
43255, August 10, 1999).

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This action would not have Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes. This 
proposed rule would not significantly nor uniquely affect the Indian 
Tribal governments, nor would it involve or impose any requirements 
that affect Indian Tribes. Accordingly, the requirements of Executive 
Order 13175 (65 FR 67249, November 9, 2000), do not apply to this 
action.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997), because this is not an economically significant 
regulatory action as defined by Executive Order 12866, and this action 
does not address environmental health or safety risks 
disproportionately affecting children.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 (66 FR 28355, 
May 22, 2001), because this proposed rule is not expected to affect 
energy supply, distribution, or use.

I. National Technology Transfer and Advancement Act (NTTAA)

    In addition, since this proposed rule would not involve any 
technical standards, NTTAA section 12(d) (15 U.S.C. 272 note), does not 
apply to this action.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    This action does not entail special considerations of environmental 
justice related issues as delineated by Executive Order 12898 (59 FR 
7629, February 16, 1994).
