Significant New Use Rules on Certain Chemical Substances (21-2.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 
pursuant to 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 December 17, 2021.

ADDRESSES: Submit your comments, identified by docket identification 
(ID) number EPA-HQ-OPPT-2021-0227, 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 December 17, 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

[[Page 64116]]

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-2021-0227, 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 
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).

    Chemical Name: Mixed amine salt (generic).
    CAS Number: Not available.
    Basis for action: The PMN states that the use of the PMN substance 
will be as a salt for polymers. Based on the estimated physical/
chemical properties of the PMN substance, test data on components of 
the PMN substance, and comparison to analogous aliphatic amines, EPA 
has identified concerns for irritation, bladder effects, 
carcinogenicity, developmental effects, corrosion, pulmonary effects, 
and aquatic toxicity if the chemical substance is not used following 
the limitation noted. The conditions of use of the PMN substance as 
described in the PMN include the following protective measure:

on the estimated physical/chemical properties of the PMN substances and 
comparison to structurally analogous chemical substances, EPA has 
identified concerns for systemic toxicity, lung toxicity, and 
irritation 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 measure:
     No spray application of the PMN substances other than by 
the method described in the spray analysis report submitted with the 
PMNs.
    The proposed SNURs would designate as a ``significant new use'' the 
absence of this protective measure.

    CFR Citation: 40 CFR 721.11686.

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

[[Page 64122]]

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 November 17, 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

[[Page 64123]]

Director, Regulatory Support Division, Office of Mission Support 
(2822T), Environmental Protection Agency, 1200 Pennsylvania Ave. NW, 
Washington, DC 20460-0001. Please remember to include the OMB control 
number in any correspondence, but do not submit any completed forms to 
this address.

C. Regulatory Flexibility Act (RFA)

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

D. Unfunded Mandates Reform Act (UMRA)

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

E. Executive Order 13132: Federalism

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

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

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

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

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

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

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

I. National Technology Transfer and Advancement Act (NTTAA)

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

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

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