Significant New Use Rules on Certain Chemical Substances (21-2.B)

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 which are 
the subject of premanufacture notices (PMNs). This action would require 
persons to notify EPA at least 90 days before commencing manufacture 
(defined by statute to include import) or processing of any of these 
chemical substances for an activity that is designated as a significant 
new use by this proposed rule. This action would further require that 
persons not commence manufacture or processing for the significant new 
use until they have submitted a Significant New Use Notice (SNUN), and 
EPA has conducted a review of the notice, made an appropriate 
determination on the notice, and has taken any risk management actions 
as are required as a result of that determination.

DATES: Comments must be received on or before June 1, 2021.

ADDRESSES: Submit your comments, identified by docket identification

SUPPLEMENTARY INFORMATION:

I. General Information

A. Does this action apply to me?

    You may be potentially affected by this action if you manufacture, 
process, or use the chemical substances contained in this proposed 
rule. The following list of North American Industrial Classification 
System (NAICS) codes is not intended to be exhaustive, but rather 
provides a guide to help readers determine whether this document 
applies to them. Potentially affected entities may include:
     Manufacturers or processors of one or more subject 
chemical substances (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries.
    This action may also affect certain entities through pre-existing 
import certification and export notification rules under TSCA. Chemical 
importers are subject to the TSCA section 13 (15 U.S.C. 2612) import 
provisions. This action may also affect certain entities through pre-
existing import certification and export notification rules 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 June 1, 2021 are subject 
to the export notification provisions of TSCA section 12(b) (15 U.S.C. 
2611(b)) 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 CBI 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) for 
chemical substances which are the subjects of PMNs P-19-82, P-20-76, 
and P-20-94. These proposed SNURs would require persons who intend to 
manufacture or process any of these chemical substances for an activity 
that is designated as a significant new use to notify EPA at least 90 
days before commencing that activity.
    The record for these proposed SNURs, identified as docket ID number 
EPA-HQ-OPPT-2020-0581, 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. Do the SNUR general provisions apply?

    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

[[Page 22925]]

40 CFR 721.1(c), persons subject to these 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 sections 5(h)(1), 
5(h)(2), 5(h)(3), and 5(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. If EPA determines 
that the chemical substance 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, and 
potential human exposures and environmental releases that may be 
associated with the substances, in the context of the four bulleted 
TSCA section 5(a)(2) factors listed in this unit. During its review of 
these chemicals, EPA identified certain conditions of use that are not 
intended by the submitters, but reasonably foreseen to occur. EPA is 
proposing to designate those reasonably foreseen conditions of use as 
well as certain other circumstances of use as significant new uses.

IV. Substances Subject to This Proposed Rule

    EPA is proposing significant new use and recordkeeping requirements 
be added to 40 CFR part 721, subpart E for the chemical substances 
identified in this unit. For each chemical substance, EPA provides the 
following information in this unit:
     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.
     Potentially useful information.
     CFR citation assigned in the regulatory text section of 
these proposed rules.
    The regulatory text section of these proposed rules specifies the 
activities designated as significant new uses. Certain new uses, 
including production volume limits and other uses designated in the 
proposed rules, may be claimed as CBI.
    The chemical substances that are the subject of these proposed 
SNURs are undergoing premanufacture review. In addition to those 
conditions of use intended by the submitter, EPA has identified certain 
other reasonably foreseen conditions of use. EPA has preliminarily 
determined that the chemicals under their intended conditions of use 
are not likely to present an unreasonable risk. However, EPA has not 
assessed risks associated with the reasonably foreseen conditions of 
use for these chemicals. EPA is proposing to designate these reasonably 
foreseen conditions of use and other circumstances of use as 
significant new uses. As a result, those significant new uses cannot 
occur without first going through a separate, subsequent EPA review and 
determination process associated with a SNUN.
    The substances subject to these proposed rules are as follows:
    PMN Number: P-19-82.
    Chemical name: Heptanal, 6-hydroxy-2,6-dimethyl-.
    CAS number: 62439-42-3.
    Basis for action: The PMN states that the use of the substance will 
be as a fragrance for scented papers, candles, detergents, cleaners, 
etc. and for non-TSCA fragrance applications. Based on the physical/
chemical properties of the substance, test data on the substance, and 
Structure Activity Relationships (SAR) analysis of test data on 
analogous substances, EPA has identified concerns for aquatic toxicity, 
eye irritation, reproductive toxicity, skin sensitization, and specific 
target organ toxicity if the chemical is not used following the 
limitations noted. This proposed SNUR designates the following as 
``significant new uses'' requiring further review by EPA:
     Processing the PMN substance to a concentration of greater 
than or equal to 1.0% in the final end use formulation.
     Release of the PMN substance resulting in surface water 
concentrations that exceed 14 ppb.
    Potentially useful information: EPA has determined that certain 
information about the effects of the PMN substance 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 aquatic toxicity, 
developmental toxicity, eye irritation/corrosion, and specific target 
organ toxicity testing would help characterize the potential 
environmental and health effects of the PMN substance.
    CFR citation: 40 CFR 721.11568.

    PMN Number: P-20-76.
    Chemical name: Glycine, reaction products with sodium O-iso-Pr 
carbonodithioate, sodium salts.
    CAS number: 2205080-23-3.
    Basis for action: The PMN states that the generic use of the 
substance will be as a mining chemical. Based on the physical/chemical 
properties of the substance, test data on the substance, and SAR 
analysis of test data on analogous substances, EPA has identified 
concerns for aquatic toxicity, carcinogenicity, genetic toxicity, 
reproductive toxicity, serious eye damage, skin corrosion, skin 
sensitization, and specific target organ toxicity if the chemical is 
not used following the limitations noted. This proposed SNUR designates 
the following as ``significant new uses'' requiring further review by 
EPA:
     Domestic manufacture of the PMN substance.
     Release of the PMN substance resulting in surface water 
concentrations that exceed 21 ppb.
    Potentially useful information: EPA has determined that certain 
information about the effects of the PMN substance 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 aquatic toxicity, 
carcinogenicity, eye irritation/corrosion, genetic toxicity, 
reproductive toxicity, skin sensitization, and specific target organ 
toxicity testing

[[Page 22926]]

would help characterize the potential environmental and health effects 
of the PMN substance.
    CFR citation: 40 CFR 721.11569.

    PMN Number: P-20-94.
    Chemical name: Alkanedioic acid, polymer with tri-alkyl-
isocyanatocarbomonocycle, dialkylglycols, ester with 2,3-
dihydroxypropyl alkyl ester, 2-hydroxyethyl methacrylate-blocked 
(generic).
    CAS number: Not Available.
    Basis for action: The PMN states that the use of the substance will 
be as a formulation component in UV/EB coatings, inks, 3D printing/
stereolithography/additive manufacturing, and adhesive manufacturing. 
Based on the physical/chemical properties of the substance and 
Structure Activity Relationships (SAR) analysis of test data on 
analogous substances, EPA has identified concerns for eye irritation, 
skin irritation, and skin sensitization, if the chemical is not used 
following the limitations noted. This proposed SNUR designates the 
following as ``significant new uses'' requiring further review by EPA:
     Use without personal protective equipment involving a 
National Institute for Occupational Safety and Health (NIOSH)-certified 
respirator with an Assigned Protection Factor (APF) of at least 50 (or 
1,000 for spray applications), unless the substance was manufactured 
with no greater than 3.5% acrylate feedstock by weight and any residual 
isocyanate in the substance is present at no greater than 0.1% by 
weight.
     Use of the PMN substance in a consumer product.
    Potentially useful information: EPA has determined that certain 
information about the effects of the PMN substance 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 occupational exposure 
monitoring would help characterize the potential effects of the PMN 
substance.
    CFR citation: 40 CFR 721.11570.

V. Rationale and Objectives of the Proposed Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances 
that are the subject of these proposed SNURs and as further discussed 
in Unit IV., EPA identified certain other reasonably foreseen 
conditions of use, in addition to those conditions of use intended by 
the submitter. EPA has preliminarily determined that the chemical under 
the intended conditions of use is not likely to present an unreasonable 
risk. However, EPA has not assessed risks associated with the 
reasonably foreseen conditions of use. EPA is proposing to designate 
these conditions of use as well as certain other circumstances of use 
as significant new uses. As a result, those significant new uses cannot 
occur without going through a separate, subsequent EPA review and 
determination process associated with a SNUN.

B. Objectives

    EPA is proposing these SNURs 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 obligated to make a determination under TSCA section 
5(a)(3) regarding the use described in the SNUN, under the conditions 
of use. The Agency will either determine under TSCA section 5(a)(3)(C) 
that the chemical, under the conditions of use, is not likely to 
present an unreasonable risk, including an unreasonable risk to a 
potentially exposed or susceptible subpopulation identified as relevant 
by the Administrator under the conditions of use, or make a 
determination under TSCA section 5(a)(3)(A) or (B) and take the 
required regulatory action associated with the determination, before 
manufacture or processing for the significant new use of the chemical 
substance can occur.
     To be able to complete its review and determination on 
each of the PMN substances, while deferring analysis on the significant 
new uses proposed in these rules unless and until the Agency receives a 
SNUN.
    Issuance of a proposed SNUR for a chemical substance does not 
signify that the chemical substance is listed on the 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.

VI. Applicability of the Proposed Rules to Uses Occurring Before the 
Effective Date of the Final Rule

    To establish a significant new use, EPA must determine that the use 
is not ongoing. The chemical substances subject to this proposed rule 
were undergoing premanufacture review at the time of signature of this 
proposed rule and were not on the TSCA Inventory. 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 
the chemical substances subject to these proposed SNURs, EPA concludes 
that the proposed significant new uses are not ongoing.
    EPA designates December 4, 2020 (date of web posting of this 
proposed rule) 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 on or after 
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 
EPA would have to take action under section 5 allowing manufacture or 
processing to proceed. In developing this proposed rule, EPA has 
recognized that, given EPA's general practice of posting proposed rules 
on its website a week or more in advance of Federal Register 
publication, this objective could be thwarted even before Federal 
Register publication of the proposed rule.

VII. Development and Submission of Information

    EPA recognizes that TSCA section 5 does not require development of 
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, 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, 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 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 for all SNURs listed here. Descriptions are provided 
for informational purposes. The potentially

[[Page 22927]]

useful information identified in Unit IV. 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 pertaining to protocol selection. 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).
    The potentially useful information described in Unit IV. may not be 
the only means of providing information to evaluate the chemical 
substance associated with the significant new uses. However, submitting 
a SNUN without any test data may increase the likelihood that EPA will 
take action under TSCA sections 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 and 721.25. 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 action proposes to establish SNURs for 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 requirements related to this action have 
already been approved by OMB pursuant to 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 section 605(b) of the RFA, 5 U.S.C. 601 et seq., I 
hereby certify 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, 12 in FY2016, 13 in FY2017, and 11 in FY2018, 
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

[[Page 22928]]

government will be impacted by this proposed rule. As such, EPA has 
determined that this proposed rule does 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. 1531-1538 et seq.).

E. Executive Order 13132: Federalism

    This action will not have federalism implications because it is not 
expected to 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 will not have Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes, 
significantly or uniquely affect the communities of Indian Tribal 
governments, and does not involve or impose any requirements that 
affect Indian Tribes, as specified in Executive Order 13175 (65 FR 
67249, November 9, 2000).

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

    This action 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 action is not expected to affect 
energy supply, distribution, or use and because this action is not a 
significant regulatory action under Executive Order 12866.

I. National Technology Transfer and Advancement Act (NTTAA)

    In addition, since this action does 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
