Significant New Use Rules on Certain Chemical Substances (21-1.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 chemical substances that were
the subject of premanufacture notices (PMNs). The chemical substances
received ``not likely to present an unreasonable risk'' determinations
under TSCA. 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 12, 2021.

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 12, 2021
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 https://www.epa.gov/dockets/commenting-epa-dockets.

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-2021-0220, 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 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

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    During review of the 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 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. The identities of many 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 12, 2021 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 http://www.epa.gov/opptintr/existingchemicals/pubs/tscainventory/index.html.

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 (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 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.
    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 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 recommended test data. EPA
encourages dialog with Agency representatives to help determine how
best the submitter can meet both the data needs and the objective of
TSCA section 4(h). For more information on alternative test methods and
strategies to reduce vertebrate animal testing, visit https://www.epa.gov/assessing-and-managing-chemicals-under-tsca/alternative-test-methods-and-strategies-reduce.
    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.

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 for this rulemaking.

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

    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).
