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 
(ID) number EPA-HQ-OPPT-2020-0131, through the Federal eRulemaking

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

[[Page 64281]]

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

[[Page 64282]]

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.

heterotrisubstituted-bile acid, 1-(difluorosulfomethyl)-2,2,2-
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 
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

    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

    PMN Number: P-18-16.
    Chemical Name: Aromatic sulfonium tricyclo fluoroalkyl sulfonic 
acid salt (generic).
    CAS Number: None available.
    Effective Date of TSCA Order: February 11, 2020.
    Basis for TSCA Order: The PMN states that the generic (non-
confidential) use will be as a photoacid generator (PAG). Based on the 
physical/chemical properties of the PMN substance, the PMN substance is 
a potentially PBT chemical (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 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 
properties and comparison with analogous chemical substances, EPA has 
also identified concerns for photosensitization, eye corrosion, 
irritation, acute toxicity, liver toxicity, neurotoxicity, 
reproductive/developmental toxicity, and aquatic 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 substance 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 the PMN substance 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 substance in any 
way that generates a dust, mist, or aerosol in a non-enclosed process;
    5. Use of the PMN substance only as described in the TSCA Order;
    6. No domestic manufacture of the PMN substance (i.e., import 
only);
    7. Import of the PMN substance only in solution, or in any form in 
sealed containers weighing 5 kilograms or less; and
    8. No exceedance of the confidential annual importation volume 
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.

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.

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;

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

[[Page 64286]]

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:

[[Page 64287]]

     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.

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

[[Page 64288]]

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).
