Significant New Use Rules on Certain Chemical Substances (20-
2.5e)

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 chemical substances that were
the subject of premanufacture notices (PMNs). The SNURs require persons
who intend to manufacture (defined by statute to include import) or
process any of these chemical substances for an activity that is
proposed as a significant new use by this rule to notify EPA at least
90 days before commencing that activity. The required notification
initiates EPA's evaluation of the use, under the conditions of use for
that chemical substance, within the applicable review period. 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 9, 2020.

ADDRESSES: Submit your comments, identified by docket identification

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
provisions promulgated at 19 CFR 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, which would include the SNUR requirements should these proposed
rules be finalized. The EPA policy in support of import certification
appears at 40 CFR part 707, subpart B. In addition, pursuant to 40 CFR
721.20, any persons who export or intend to export a chemical substance
that is the subject of this proposed rule on or after November 9, 2020
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) (15 U.S.C.
2604(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 any of these
chemical substances for an 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.
    The docket for these proposed SNURs, identified as docket ID number
EPA-HQ-OPPT-2020-0131, includes information considered by the Agency in
developing these proposed SNURs.

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

    TSCA section 5(a)(2) (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 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 rule, recordkeeping
requirements, 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 these SNURs must comply with the
same significant new use notice (SNUN) requirements and EPA regulatory
procedures as submitters of PMNs under TSCA section 5(a)(1)(A). These
requirements include the information submission requirements of TSCA
sections 5(b) and 5(d)(1), the exemptions authorized by TSCA

sections 5(h)(1), (h)(2), (h)(3), and (h)(5), and the regulations at 40
CFR part 720. Once EPA receives a SNUN and before the manufacture or
processing for the significant new use can commence, 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. 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 what would constitute a significant new use for the
chemical substances that are the subject of these SNURs, EPA considered
relevant information about the toxicity of the chemical substances,
potential human exposures and environmental releases that may be
associated with possible uses of these chemical substances, in the
context of the four TSCA section 5(a)(2) factors listed in this unit.
    The proposed rules include 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). The TSCA Orders
require protective measures to limit exposures or otherwise mitigate
the potential unreasonable risk. The proposed SNURs identify
significant new uses as any manufacturing, processing, use,
distribution in commerce, or disposal that does not conform to the
restrictions imposed by the underlying TSCA Orders, consistent with
TSCA section 5(f)(4).
    Where EPA determined that the PMN substance may present an
unreasonable risk of injury to human health via inhalation exposure,
the underlying TSCA Order usually requires that potentially exposed
employees wear specified respirators unless actual measurements of the
workplace air show that air-borne concentrations of the PMN substance
are below a New Chemical Exposure Limit (NCEL), and includes
requirements addressing performance criteria for sampling and
analytical methods, periodic monitoring, respiratory protection, and
recordkeeping. No comparable NCEL provisions currently exist in 40 CFR
part 721, subpart B, for SNURs. Therefore, for these cases, the
individual SNURs in 40 CFR part 721, subpart E, will state that persons
subject to the SNUR who wish to pursue NCELs as an alternative to the
40 CFR 721.63 respirator requirements may request to do so under 40 CFR
721.30. EPA expects that persons whose 40 CFR 721.30 requests to use
the NCELs approach for SNURs that are approved by EPA will be required
to comply with NCELs provisions that are comparable to those contained
in the corresponding TSCA Order for the same chemical substance.
    These proposed rules include 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. The proposed SNURs would identify as significant new uses
any manufacturing, processing, use, distribution in commerce, or
disposal that does not conform to the protection measures.

IV. Substances Subject to This Proposed Rule

    EPA is proposing significant new use and recordkeeping requirements
for certain chemical substances in 40 CFR part 721, subpart E. In this
unit, EPA provides the following information for each chemical
substance that is identified in this unit as subject to this proposed
rule:
     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 TSCA Order.
     Effective date of the TSCA Order (if applicable).
     Potentially Useful Information.
     CFR citation assigned in the regulatory text section of
the proposed rule.
    The chemicals subject to these proposed SNURs are as follows:
    PMN Numbers: P-18-241, P-18-244, and P-18-245.
    Chemical Names: 2-Propenoic acid, 2-methyl-, methyl ester, polymer
with ethenylbenzene, ethyl 2-propenoate, 2-oxiranylmethyl 2-methyl-2-
propenoate and 1,2-propanediol mono(2-methyl-2-propenoate), reaction
products with diethanolamine, polymers with substituted-alkyl acrylate,
formats (salts) (P-18-241) (generic); 2-Propenoic acid, 2-methyl,
methyl ester, polymer with ethenylbenzene, ethyl 2-propenoate, 2-
oxiranylmethyl 2-methyl-2-propenoate and 1,2-propanediol mono(2-methyl-
2-propenoate), reaction products with diethanolamine, polymers with
substituted-alkyl methacrylate, formats (salts) (P-18-244) (generic);
2-Propenoic acid, 2-methyl-, methyl ester, polymer with ethenylbenzene,
ethyl 2-propenoate, 2-oxrianylmethyl 2-methyl-2-propenoate, and 1,2-
propaneidol mono(2-methyl-2-propenoate), reaction products with
diethanolamine, polymers with alkylene glycol monoacrylate, formats
(salts) (P-18-245) (generic).
    CAS Numbers: Not available.
    Basis for the action: The PMNs state that the generic (non-
confidential) use of the substances will be as additives for automotive
coatings. EPA estimated the human health hazard of the chemical
substances based on their measured and estimated physical/chemical
properties and by comparison with structurally analogous chemical
substances. EPA determined environmental hazard for the new chemical
substances based on Structural Activity Relationships (SAR) analysis
for polycationic polymers. EPA has identified concerns for potential
neurotoxicity, blood toxicity, reproductive and developmental toxicity,
and moderate environmental hazard if the chemical substances are not
manufactured and not used following the limitations identified by the
submitters in the notices. This proposed SNUR designates the following
circumstances of use as ``significant new uses'' requiring further
review by EPA:
     Use of the PMN substances other than as described in the
PMNs.
    Potentially useful information: EPA has determined that information
about the human health and environmental effects of the PMN substances
may be potentially useful 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
neurotoxicity, reproductive/developmental toxicity, and aquatic

toxicity testing would help characterize the potential health and
environmental effects of the PMN substances.
    CFR Citations: 40 CFR 721.11401 (P-18-241), 40 CFR 721.11402 (P-18-
244), and 40 CFR 721.11403 (P-18-245).

    PMN Numbers: P-16-539, P-18-157, P-18-158, P-18-159, and P-19-33.
    Chemical Names: Organic sulfonate compound (generic) (P-16-539),
thiophenium, 1-(2,7-disubstituted-1-naphthalenyl)tetrahydro-, salt with
polyfluoro-N-polyfluoroalkylsulfonyl-1-alkanesulfonamide (1:1)
(generic) (P-18-157), sulfonium, triphenyl-, salt with 2,3-
bis(substituted) 5-sulfocarbopolycyclic-2,3-carboxylate derivative
(1:1) (generic) (P-18-158), thiophenium, 1-(2,7-disubstituted-1-
naphthalenyl)tetrahydro-, salt with polyfluoro-N-
polyfluoroalkylsulfonyl-1-alkanesulfonamide (1:1) (P-18-159), and
sulfonium, triphenyl-, 5-(alkyl) fluoropentane derivative (generic) (P-
19-33).
    CAS Numbers: Not available.
    Effective Date of TSCA Order: January 31, 2020.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) use of the substances will be for photolithography (P-16-
539, P-18-158, and P-19-33) and as a photosensitizer for photoresist
(P-18-158 and P-18-159). Based on the physical/chemical properties of
the PMN substances and test data on structurally similar substances,
the PMN substances are potentially persistent, bioaccumulative, and
toxic (PBT) chemicals (as described in the New Chemical Program's PBT
category policy statement (64 FR 60194, November 4, 1999; FRL-6097-7)).
EPA estimates that the PMN substances will persist in the environment
for more than 2 months and estimates a bioaccumulation factor of
greater than or equal to 1,000. Based on physical/chemical properties
and comparison with analogous chemical substances, EPA has also
identified concerns for photosensitization, eye corrosion, irritation,
acute toxicity, neurotoxicity, lung overload, aquatic toxicity, and
reproductive/developmental toxicity. The TSCA 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 substances may present an unreasonable risk of
injury to human health or the environment. To protect against these
risks, the TSCA Order requires:
    1. No manufacture of any of the PMN substances beyond the time
limits specified in the TSCA Order without submittal to EPA of the
results of certain testing described in the Testing section of the TSCA
Order;
    2. Use of personal protective equipment where there is a potential
for dermal exposure;
    3. Establishment of a hazard communication program, including human
health precautionary statements on each label and in the Safety Data
Sheet (SDS);
    4. No modification of the processing of the PMN substances in any
way that generates a dust, mist, or aerosol in a non-enclosed process;
    5. Use of the PMN substances only as described in the TSCA Order;
    6. No domestic manufacture of the PMN substances (i.e., import
only);
    7. Import of the PMN substances only in solution, or in any form in
sealed containers weighing 5 kilograms or less; and
    8. No exceedance of the confidential annual production volumes
listed in the TSCA 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 about the physical/chemical properties, fate,
bioaccumulation, environmental hazard, and human health effects of the
PMN substance may be potentially useful in support of a request by the
PMN submitter to modify the TSCA Order, or if a manufacturer or
processor is considering submitting a SNUN for a significant new use
that will be designated by this SNUR. The submitter has agreed not to
exceed the time limits specified in the TSCA Order without performing
the required Tier I and Tier II testing outlined in the Testing section
of the TSCA Order.

trifluoroethyl ester, ion(1-), (5)-, triphenylsulfonium (1:1) (generic)
(P-19-133).
    CAS Numbers: Not available.
    Effective Date of TSCA Order: January 31, 2020.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) uses of the substances will be for microlithography for
electronic device manufacturing (P-17-178, P-18-13, P-18-14, and P-18-
37), polymers for photo resist (P-19-78 and P-17-79), and
microlithography for electronic device manufacturing (P-19-78, P-19-79,
P-19-111, P-19-112, P-19-114, and P-19-133). Based on the physical/
chemical properties of the PMN substances and test data on structurally
similar substances, the PMN substances are potentially PBT chemicals
(as described in the New Chemical Program's PBT category policy

    CFR Citation: 40 CFR 721.11529.

    PMN Numbers: P-18-297, P-18-311, P-18-314, and P-18-315.
    Chemical Names: Substituted, (alkylaromatic)diaromatic salt with
trihalo-[(trihaloalkyl)substituted]substituted alkaneamide (generic)
(P-18-297), triarylsulfonium substituted oxatricycloalkyloxycarbonyl
dihalo alkane sulfonate (generic) (P-18-311), substituted
triarylsulfonium carbopolycyclic heteromonocyclic dihalo sulfoacetate
(generic) (P-18-314), and substituted triarylsulfonium substituted
carbopolycyclic carboxylate (generic) (P-18-315).
    CAS Numbers: Not available.
    Effective Date of TSCA Order: February 4, 2020.
    Basis for TSCA Order: The PMNs state that the generic (non-
confidential) use of the substances will be as components of material
for fabrication. Based on the physical/chemical properties of the PMN
substances and test data on structurally similar substances, the PMN
substances are potentially PBT chemicals (as described in the New
Chemical Program's PBT category policy statement (64 FR 60194, November
4, 1999; FRL-6097-7)). 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
physical/chemical properties and comparison with analogous chemical
substances, EPA has also identified concerns for photosensitization,
eye corrosion, irritation, acute toxicity, neurotoxicity, lung
overload, aquatic toxicity, and reproductive/developmental toxicity.
The 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
substances may present an unreasonable risk of injury to human health
or the environment. To protect against these risks, the TSCA Order
requires:
    1. No manufacture of any of the PMN substances beyond the time
limits specified in the TSCA Order without submittal to EPA of the
results of certain testing described in the Testing section of the TSCA
Order;
    2. Use of personal protective equipment where there is a potential
for dermal exposure;
    3. Establishment of a hazard communication program, including human
health precautionary statements on each label and in the SDS;
    4. No modification of the processing of the PMN substances in any
way that generates a dust, mist, or aerosol in a non-enclosed process;
    5. Use of the PMN substances only as described in the TSCA Order;
    6. No domestic manufacture of the PMN substances (i.e., import
only);
    7. Import of the PMN substances only in solution, or in any form in
sealed containers weighing 5 kilograms or less; and
    8. No exceedance of the confidential annual importation volumes
listed in the TSCA 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 about the physical/chemical properties, fate,
bioaccumulation, environmental hazard, and human health effects of the
PMN substance may be potentially useful in support of a request by the
PMN submitter to modify the TSCA Order, or if a manufacturer or
processor is considering submitting a SNUN for a significant new use
that will be designated by this SNUR. The submitter has agreed not to
exceed the time limits specified in the TSCA Order without performing
the required Tier I and Tier II testing outlined in the Testing section
of the TSCA Order.

physical/chemical properties of the PMN substance, the PMN substance is
a potentially persistent, bioaccumulative, and toxic (PBT) chemical (as
described in the New Chemical Program's PBT category at 64 FR 60194;
November 1999). EPA estimates that the PMN substance will persist in
the environment for more than 2 months and estimates a bioaccumulation
factor of greater than or equal to 1,000. Based on physical/chemical

    Basis for TSCA Order: The PMNs states that the generic (non-
confidential) use will be to monitor oil and gas well performance (P-
19-180, P-19-181, P-19-182, P-19-184, and P-19-187) and as well

estimated physical/chemical properties of the PMN substances and
comparison with analogous chemical substances, EPA has identified
concerns for developmental toxicity and neurotoxicity for all of the
PMN substances and additionally irritation to skin, eyes, and
respiratory tract for P-19-168, P-19-169, P-19-171, P-19-172, P-19-173,

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 or the environment. To
protect against these risks, the TSCA Order requires:
    1. No manufacture (including import), processing, or use of any of
the PMN substances other than for the confidential use described in
each PMN;
    2. Submission to EPA of certain toxicity testing before
manufacturing (including import) beyond the confidential cumulative
production volumes listed in the Testing Section of the TSCA Order;
    3. Use of personal protective equipment where there is a potential
for dermal exposure to PMN substances P-19-168, P-19-169, P-19-171, P-
19-172, P-19-173, P-19-175, P-19-176, P-19-177, P-19-178, or P-19-179;
    4. Use of engineering controls/processes as specified in the TSCA
Order;
    5. Use of a NIOSH-certified respirator with an APF of at least 10
where there is a potential for inhalation exposure to PMN substances P-
19-168, P-19-169, P-19-171, P-19-172, P-19-173, P-19-175, P-19-176, P-
19-177, P-19-178, or P-19-179 or compliance with a NCEL of 0.0195 mg/
m\3\ as an 8-hour time-weighted average to prevent inhalation exposure;
    6. Establishment and use of a hazard communication program,
including human health precautionary statements on each label and in
the SDS;
    7. No manufacture or use of PMN substances P-19-180, P-19-181, P-
19-182, P-19-184, or P-19-187 other than in liquid formulations; and
    8. No manufacture of the PMN substances P-19-168, P-19-169, P-19-
171, P-19-172, P-19-173, P-19-175, P-19-176, P-19-177, P-19-178, or P-
19-179 beyond the confidential annual production volume limit specified
in the TSCA 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 about the human health effects of the PMN substances may be
potentially useful in support of a request by the PMN submitter to
modify the TSCA Order, or if a manufacturer or processor is considering
submitting a SNUN for a significant new use that will be designated by
this SNUR. EPA has determined that the results of skin irritation, eye
damage, neurotoxicity, reproductive/developmental toxicity, pulmonary
effects, and specific target organ toxicity testing may be potentially
useful to characterize the human health effects of the PMN substances.
Although the TSCA Order does not require these tests, the TSCA Order's
restrictions remain in effect until the TSCA Order is modified or
revoked by EPA based on submission of this or other relevant
information.

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    During review of the PMNs submitted for some of the chemical
substances that are the subject to these proposed SNURs, EPA concluded
that 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 the TSCA
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 chemical substances that are the subject
of these proposed SNURs and as further discussed in Unit IV., EPA
identified certain other circumstances of use different from the
intended conditions of use identified in the PMNs and determined that
those changes 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.

B. Objectives

    EPA is proposing these SNURs for specific chemical substances which
have undergone premanufacture review because the Agency wants:
     To 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 Orders,
consistent with TSCA section 5(f)(4).
     To have an opportunity 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 be able 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.

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 Orders have been issued for 42
of the 45 chemical substances that are the subject of this proposed
SNUR, and the PMN submitters are prohibited by the TSCA Orders from
undertaking activities which would be designated as significant new
uses. The identities of all of the chemical substances subject to this
proposed rule have been claimed as confidential per 40 CFR 720.85.
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 9, 2020 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.
    In the unlikely event that a person began 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.
    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
https://www.epa.gov/tsca-inventory.

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: If a person is required to
submit information for a chemical substance pursuant to a rule, TSCA
Order or consent agreement under TSCA section 4, then TSCA section
5(b)(1)(A) requires such information to be submitted to EPA at the time
of submission of the SNUN.
    In the absence of a rule, TSCA Order, or consent agreement under
TSCA section 4 covering the chemical substance, persons are required
only to submit information in their possession or control and to
describe any other information known or reasonably ascertainable (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 for all SNURs listed here. Descriptions of this
information is provided for informational purposes. The potentially
useful information identified in Unit IV. of the proposed rule will be
useful to EPA's evaluation in the event that someone submits a SNUN for
the significant new use. Companies who are considering submitting a
SNUN are encouraged, but not required, to develop the information on
the substance, which may assist with EPA's analysis of the SNUN. EPA
strongly encourages persons, before performing any testing, to consult
with the Agency. Furthermore, pursuant to TSCA section 4(h), which
pertains to reduction of testing on vertebrate animals, EPA encourages
dialog 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 OCSPP test guidelines referenced in
this document electronically, please go to http://www.epa.gov/ocspp and
select ``Test Methods and Guidelines.'' The Organisation for Economic
Co-operation and Development (OECD) test guidelines are available from
the OECD Bookshop at http://www.oecdbookshop.org or SourceOECD at
http://www.sourceoecd.org.
    The potentially useful information listed in Unit IV. may not be
the only means of addressing the potential risks of the chemical
substance. However, submitting a SNUN without any test data or other
information may increase the likelihood that EPA will take action under
TSCA section 5(e) or 5(f). 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.
     Information on risks posed by the chemical substances
compared to risks posed by potential substitutes.

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. E-PMN software is available electronically
at https://www.epa.gov/reviewing-new-chemicals-under-toxic-substances-control-act-tsca.

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 under docket ID number EPA-HQ-OPPT-
2020-0131.

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.

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. 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 the 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 activities related to this action have
already been approved by OMB under the PRA under OMB control number
2070-0012 (EPA ICR No. 574). This proposed rule does not contain 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 using
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 the RFA section 605(b) (5 U.S.C. 601 et seq.), the
Agency hereby certifies that promulgation of these SNURs 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. 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
action would not significantly nor uniquely affect the communities of
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 proposed rule 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 proposed rule 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)

    This action does not involve any technical standards subject to
NTTAA section 12(d) (15 U.S.C. 272 note).

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).
