Significant New Use Rules on Certain Chemical Substances (19-4.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 26 chemical substances which 
were the subject of premanufacture notices (PMNs). Five of these 
chemical substances are subject to Orders issued by EPA pursuant to 
TSCA, and the remaining 21 of these chemical substances received a 
``not likely to present an unreasonable risk'' determination pursuant 
to TSCA. This action would require persons who intend to manufacture 
(defined by statute to include import) or process any of these 26 
chemical substances for an activity that is proposed as a significant 
new use 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 December 4, 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

[[Page 59336]]

(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 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 
December 4, 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). 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?

    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 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 sections 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 26 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 five 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 21 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 26 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 5(e) Order.
     Potentially Useful Information. This is information 
identified by EPA that

[[Page 59337]]

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.
     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 five PMN substances that are subject 
to Orders issued under TSCA section 5(e)(1)(A), as required by the 
determinations made under section 5(a)(3)(B). Those 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 Orders, consistent with TSCA section 5(f)(4).
    These proposed rules also include 21 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, but the TSCA section 5(a)(3)(C) 
determinations did not deem such uses as reasonably foreseen. 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 Number: P-16-548

    Chemical Name: Triarylsulfonium salt (generic).
    CAS Number: Not available.
    Effective date of TSCA section 5(e) Order: July 22, 2019.
    Basis for TSCA section 5(e) Order: The PMN states that the generic 
(non-confidential) use of the PMN substance will be as a resin 
catalyst. Based on physical/chemical properties of the PMN substance 
(as described in the New Chemical Program's PBT category at 64 FR 
60194; November 1999), the PMN substance is a potentially persistent, 
bioaccumulative, and toxic (PBT) chemical. EPA estimates that that 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 comparison to structurally analogous chemical substances, the 
estimated physical/chemical properties of the PMN, and test data for 
the PMN substance, EPA has identified concerns for eye irritation, 
systemic, developmental, blood, and reproductive effects. 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 and the environment. To protect against 
these risks, the Order requires:
    1. Refraining from domestic manufacture in the United States (i.e., 
import only);
    2. Use of the PMN substance only for the confidential use specified 
in the Order;
    3. No manufacture (including import) of the PMN substance beyond 
the confidential annual manufacture volume specified in the Order;
    4. Refraining from processing or using the PMN substance in any 
manner that generates a mist, vapor, or aerosol; and
    5. No release of the PMN substance into the waters of the United 
States.
    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 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 
specific target organ toxicity and reproductive/developmental toxicity 
testing would help characterize the potential health 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.

PMN Numbers: P-17-312, P-17-313, P-17-314, P-17-315, P-17-316, and P-
17-317

disubstituted amine-disubstituted polypropylene glycol reaction 
products (generic) (P-17-312); Phenol, 4,4'-(1-methylethylidene)bis-,

omega-(2-oxiranylmethoxy)poly[oxy(methyl-1,2-ethanediyl)], alkylphenyl 
ethers, reaction products with disubstituted amine, organic acid salts 
(generic) (P-17-315); Organic acid, compds. with bisphenol A-

bisphenol A-epichlorohydrin-polypropylene glycol diglycidyl ether 
polymer-disubstituted polypropylene glycol reaction products (generic) 
(P-17-317).
    CAS Numbers: Not available.
    Basis for action: The PMNs state that the generic (non-
confidential) use of the substances will be as additives for 
electrocoat. Based on the estimated physical/chemical properties of the 
PMN substances, comparison with structurally analogous substances, and 
Structural Activity Relationships (SAR) analysis on analogous 
polycationic polymers, EPA has identified concerns for lung effects, 
nasal epithelial damage, skin and eye irritation, and aquatic toxicity 
if the chemical substances are not used following the limitations 
noted. The conditions of use of the PMN substances as described in the 
PMNs include the following protective measures:
    1. No modification of the manufacturing, processing, or use of the 
PMN substances that result in the

[[Page 59338]]

generation of a dust, mist, or aerosol; and
    2. No release of a manufacturing, processing, or use stream 
associated with any use of the PMN substance into the waters of the 
United States exceeding a surface water concentration of 78 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 substances 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, skin irritation/corrosion, eye 
damage, and acute aquatic toxicity testing would help characterize the 
potential health effects of the PMN substances.

313), 40 CFR 721.11386 (P-17-314), 40 CFR 721.11387 (P-17-315), 40 CFR 
721.11388 (P-17-316), and 40 CFR 721.11389 (P-17-317).

PMN Numbers: P-17-398, P-17-399, P-18-1, and P-18-28

    Chemical names: Branched cyclic and linear hydrocarbons from 
plastic depolymerization (generic) (P-17-398), Alkane, alkene, styrenic 
compounds derived from plastic depolymerization (generic) (P-17-399), 
Carbon compound derived from plastic depolymerization (generic) (P-18-
1), and Branched cyclic and linear hydrocarbons from plastic 
depolymerization (generic) (P-18-28).
    CAS numbers: Not available.
    Effective date of TSCA section 5(e) Order: June 10, 2019.
    Basis for TSCA section 5(e) Order: The PMNs state that the use of 
P-17-398 and P-17-399 will be as a refinery feedstock or fuel blending 
additive, the generic use of P-18-1 will be as an additive, and the use 
of P-18-28 will be as a chemical feedstock. Based on the physical/
chemical properties of the PMN substances and comparison to 
structurally analogous chemical substances, EPA has identified concerns 
for neurological impairment, and hematological effects including 
aplastic anemia and acute myelogenous leukemia for PMN substance P-18-
28. There is concern for lung effects for P-18-1, if respirable, based 
on the respirable, poorly soluble particles category. Based on SAR 
analysis on analogous substances, EPA predicts toxicity to aquatic 
organisms may occur at concentrations that exceed 1 ppb for P-17-398 
and P-17-399, and 15 ppb for P-18-28. 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 and the environment. The Order was also issued under 
TSCA sections 5(a)(3)(B)(ii)(II) and 5(e)(1)(A)(ii)(II), based on a 
finding that the substances are or will be produced in substantial 
quantities and that the substances either enter or may reasonably be 
anticipated to enter the environment in substantial quantities, or 
there is or may be significant (or substantial) human exposure to the 
substances. To protect against these risks, the Order requires:
    1. Refraining from manufacturing, processing, or using P-17-398 and 
P-17-399 other than as a refinery feedstock or a fuel blending additive 
and refrain from manufacturing, processing, and using P-18-28 other 
than as a chemical feedstock or a fuel blending additive;
    2. Manufacture of P-18-1 via the enclosed manufacturing process 
described in the PMN; and
    3. Manufacture of P-18-1 according to the particle sizes described 
in the PMN: 1% or less of the particles at less than 75 microns.
    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 and environmental effects of the PMN 
substances 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 additional particle size characterization testing for P-18-1 
and acute and chronic aquatic toxicity testing for P-17-398, P-17-399, 
and P-18-28 would help EPA determine the potential human and 
environmental effects of the PMN substances. Although the TSCA section 
5(e) Order does not require this information, the Order's restrictions 
remain in effect until the Order is modified or revoked by EPA based on 
submission of this or other relevant information.

399), 40 CFR 721.11392 (P-18-1), and 40 CFR 721.11393 (P-18-28).

PMN Number: P-18-9

    Chemical Name: Phosphonic acid, dimethyl ester, polymer with alkyl 
diols (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 lubricant additive. 
Based on estimated physical/chemical properties of the PMN substance, 
test data on the PMN substance, comparison to structurally analogous 
chemical substances, and SAR analysis of test data on analogous esters, 
EPA has identified concerns for gastrointestinal and kidney effects, 
reproductive/developmental 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 measures:
    1. No release of a manufacturing, processing, or use stream 
associated with any use of the PMN substance into the waters of the 
United States exceeding a surface water concentration of 300 ppb; and
    2. No manufacture, process, or use of the PMN substance that 
generates a dust, mist, or aerosol.
    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 aquatic toxicity, specific target organ toxicity, and 
reproductive/developmental toxicity testing would help characterize the 
potential health and environmental effects of the PMN substance.
    CFR Citation: 40 CFR 721.11394.

PMN Number: P-18-11

    Chemical Name: 1H-Imidazole, 1,2,4,5-tetramethyl-.
    CAS Number: 1739[hyphen]83[hyphen]9.
    Basis for action: The PMN states that the use of the PMN substance 
will be as a chemical intermediate in the synthesis of a polymer. Based 
on estimated physical/chemical properties of the PMN substance, test 
data on analogous chemical substances, comparison to structurally 
analogous chemical substances, and SAR analysis of test data on 
analogous pyrroles/diazoles, EPA has identified concerns for irritation 
and corrosion to all tissues,

[[Page 59339]]

developmental effects, liver 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 measures:
    1. Refraining from domestic manufacture in the United States (i.e., 
import only);
    2. No release of a manufacturing, processing, or use stream 
associated with any use of the PMN substance into the waters of the 
United States exceeding a surface water concentration of 7 ppb; and
    3. No use of the PMN substance other than as a chemical 
intermediate.
    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 skin corrosion, developmental/reproductive toxicity, 
specific target organ toxicity, and aquatic toxicity testing would help 
characterize the potential health and environmental effects of the PMN 
substance.
    CFR Citation: 40 CFR 721.11395.

PMN Number: P-18-170

    Chemical Name: 1-Propanaminium, N,N'-(oxydi-2,1-ethanediyl)bis[3-
chloro-2-hydroxy-N,N-dimethyl-, chloride (1:2).
    CAS Number: 96320-92-2.
    Basis for action: The PMN states that the generic (non-
confidential) use of the PMN substance will be for use in textile 
treatment. Based on the physical/chemical properties of the PMN 
substance, comparison of structurally analogous chemical substances, 
and SAR analysis on cationic surfactants, EPA has identified concerns 
for surfactant effects on the lungs, developmental effects, 
mutagenicity, carcinogenicity, systemic toxicity, skin and respiratory 
sensitization, liver and kidney 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 measures:
    1. No manufacturing, processing, or use of the PMN substance that 
results in inhalation exposures; and
    2. No release of a manufacturing, processing, or use stream 
associated with any use of the PMN substance into the waters of the 
United States exceeding a surface water concentration of 164 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 specific target organ toxicity, reproductive/
developmental toxicity, and chronic aquatic toxicity testing would help 
characterize the potential health and environmental effects of the PMN 
substance.
    CFR Citation: 40 CFR 721.11396.

    CFR Citation: 40 CFR 721.11411.

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 five 
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 21 chemical substances that are the 
subject of these SNURs and as further discussed in Unit IV, EPA 
identified certain circumstances that raised potential risk concerns. 
EPA determined that deviations from the limitations 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 certain limitations in the submission.

B. Objectives

    EPA is proposing these SNURs for specific chemical substances which 
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 five of the 26 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 21 of the 26 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 November 4, 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 of 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

[[Page 59343]]

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 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. 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 under docket ID number EPA-HQ-OPPT-
2019-0494.

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 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 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 the 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 in this proposed rule have 
already been approved by OMB pursuant to the 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 
through 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 RFA section 605(b) (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.).

[[Page 59344]]

E. Executive Order 11632: Federalism

    This proposed rule 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 proposed rule 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 
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 and because this proposed 
rule is not a significant regulatory action under Executive Order 
12866.

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