Significant New Use Rules on Certain Chemical Substances (19-5.B)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: EPA is issuing 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 requires 
persons to

[[Page 46551]]

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 rule. The required notification initiates EPA's evaluation of 
the chemical under the conditions of use 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 Significant 
New Use Notice (SNUN), made an appropriate determination on the SNUN, 
and has taken such actions as are required as a result of that 
determination.

DATES: This rule is effective on October 2, 2020. For purposes of 
judicial review, this rule shall be promulgated at 1 p.m. (e.s.t.) on 
August 17, 2020.

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 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. Importers of chemicals subject to these 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 rule 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.

II. Background

A. What action is the Agency taking?

    EPA is finalizing SNURs under TSCA section 5(a)(2) for chemical 
substances which were the subject of PMNs P-17-324, P-18-109, P-18-276, 
P-18-358, P-18-384, and P-19-24. These SNURs 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.
    Previously, in the Federal Register of September 11, 2019 (84 FR 
47923) (FRL-9999-27), EPA proposed SNURs for these chemical substances 
and established the record for these SNURs in the docket under docket 
ID number EPA-HQ-OPPT-2019-0495. That docket includes information 
considered by the Agency in developing the proposed and final rules, 
including public comments and EPA's responses to the public comments 
received.

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 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. According 
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). In 
particular, 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, EPA must 
either determine that the significant new use is not likely to present 
an unreasonable risk of injury 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 significant new 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:

[[Page 46552]]

     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 addition to these factors enumerated in TSCA section 5(a)(2), 
the statute authorizes EPA to consider any other relevant factors.
    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 
finalizing its proposed designation of those reasonably foreseen 
conditions of use as well as certain other circumstances of use as 
significant new uses.

IV. Public Comments on Proposed Rule and EPA Responses

    EPA received public comments from two identifying entities on the 
proposed rule. The Agency's responses are presented in the Response to 
Public Comments document that is available in the docket for this rule. 
In response to public comment, EPA has modified the significant new use 
in the SNUR at 40 CFR 721.11379 to refer more generally to the 
manufacture of 6-lithium halide scintillation crystals.

V. Substances Subject to This Rule

    EPA is establishing significant new use and recordkeeping 
requirements for chemical substances in 40 CFR part 721, subpart E. In 
Unit IV. of the proposed SNUR (see Unit II.A.), EPA provided 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.
     Potentially Useful Information.
     CFR citation assigned in the regulatory text section of 
these rules.
    The regulatory text section of these rules specifies the activities 
designated as significant new uses. Certain new uses, including 
production volume limits and other uses designated in the rules, may be 
claimed as CBI.
    The chemical substances that are the subject of the SNURs addressed 
in this document completed premanufacture review. In addition to those 
conditions of use intended by the submitter, EPA has identified certain 
other reasonably foreseen conditions of use as well as other 
circumstances 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 designating these reasonably foreseen 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 the SNUN.

VI. Rationale and Objectives of the Rule

A. Rationale

    During review of the PMNs submitted for the chemical substances 
that are the subject of these SNURs and as further discussed in Unit 
IV. of the proposed rule, EPA identified certain reasonably foreseen 
conditions of use as well as certain other circumstances of use 
different from the intended conditions of use identified in the PMNs 
and determined that those changes could result in changes in the type 
or form of exposure to the chemical substances and/or increased 
exposures to the chemical substances and/or changes in the reasonably 
anticipated manner and methods of manufacturing, processing, 
distribution in commerce, and disposal of the chemical substances.

B. Objectives

    EPA is issuing these SNURs 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 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 before the significant new use may commence. The Agency will 
either determine under TSCA section 5(a)(3)(C) that the significant new 
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.
    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. Applicability of the 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 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.
    EPA designated September 4, 2019 (the date of web posting of the 
proposed rule) as the cutoff date for determining whether the new use 
is ongoing. The objective of EPA's approach has been to ensure that a 
person could not 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, that person will have to cease any such 
activity upon the effective date of the final rule. To resume their 
activities, that person 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.

[[Page 46553]]

VIII. 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 (15 U.S.C. 2603), then TSCA 
section 5(b)(1)(A) (15 U.S.C. 2604(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. of the proposed rule 
lists potentially useful information for all SNURs listed in this 
document. Descriptions are provided for informational purposes. The 
information identified in Unit IV. of the proposed rule will be 
potentially 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.
    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).
    The potentially useful information described in Unit IV. of the 
proposed rule 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 that provide detailed information on the following:
     Human exposure and environmental release that may result 
from the significant new use of the chemical substances.
     Information on risks posed by the chemical substances 
compared to risks posed by potential substitutes.

IX. Procedural Determinations

    By this rule, EPA is establishing certain significant new uses 
which have been claimed as CBI subject to Agency confidentiality 
regulations at 40 CFR part 2 and 40 CFR part 720, subpart E. Absent a 
final determination or other disposition of the confidentiality claim 
under 40 CFR part 2 procedures, EPA is required to keep this 
information confidential. EPA promulgated a procedure to deal with the 
situation where a specific significant new use is CBI, at 40 CFR 
721.1725(b)(1).
    Under these procedures a manufacturer or processor may request EPA 
to determine whether a proposed use would be a significant new use 
under the rule. The manufacturer or processor must show that it has a 
bona fide intent to manufacture or process the chemical substance and 
must identify the specific use for which it intends to manufacture or 
process the chemical substance. If EPA concludes that the person has 
shown a bona fide intent to manufacture or process the chemical 
substance, EPA will tell the person whether the use identified in the 
bona fide submission would be a significant new use under the rule. 
Since most of the chemical identities of the chemical substances 
subject to these SNURs are also CBI, manufacturers and processors can 
combine the bona fide submission under the procedure in 40 CFR 
721.1725(b)(1) with that under 40 CFR 721.11 into a single step.
    If EPA determines that the use identified in the bona fide 
submission would not be a significant new use, i.e., the use does not 
meet the criteria specified in the rule for a significant new use, that 
person can manufacture or process the chemical substance so long as the 
significant new use trigger is not met. In the case of a production 
volume trigger, this means that the aggregate annual production volume 
does not exceed that identified in the bona fide submission to EPA. 
Because of confidentiality concerns, EPA does not typically disclose 
the actual production volume that constitutes the use trigger. Thus, if 
the person later intends to exceed that volume, a new bona fide 
submission would be necessary to determine whether that higher volume 
would be a significant new use.

X. 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.

XI. Economic Analysis

    EPA has evaluated the potential costs of establishing SNUN 
requirements for potential manufacturers and processors of the chemical 
substances subject to this rule. EPA's complete economic analysis is 
available in the docket under docket ID number EPA-HQ-OPPT-2019-0495.

XII. 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 establishes 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 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. EPA is amending the table in 40 CFR part 9 to list the OMB 
approval number for the information collection requirements contained 
in this action. This listing of the OMB control numbers

[[Page 46554]]

and their subsequent codification in the CFR satisfies the display 
requirements of PRA and OMB's implementing regulations at 5 CFR part 
1320. This Information Collection Request (ICR) was previously subject 
to public notice and comment prior to OMB approval, and given the 
technical nature of the table, EPA finds that further notice and 
comment to amend it is unnecessary. As a result, EPA finds that there 
is ``good cause'' under section 553(b)(3)(B) of the Administrative 
Procedure Act (5 U.S.C. 553(b)(3)(B)) to amend this table without 
further notice and comment.
    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 Regulatory Flexibility Act (RFA) 
(5 U.S.C. 601 et seq.), the Agency hereby certifies that promulgation 
of this 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, EPA has concluded 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, EPA 
received 7 SNUNs in Federal fiscal year (FY) 2013, 13 in FY2014, 6 in 
FY2015, 10 in FY2016, 14 in FY2017, and 11 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 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 action 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. 1501 et seq.).

E. Executive Order 13132: Federalism

    This action will 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, entitled 
``Federalism'' (64 FR 43255, August 10, 1999).

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

    This action does not have Tribal implications because it is not 
expected to have substantial direct effects on Indian Tribes. This 
action does not significantly nor uniquely affect the communities of 
Indian Tribal governments, nor does 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 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 action 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

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

XIII. Congressional Review Act (CRA)

    Pursuant to the CRA (5 U.S.C. 801 et seq.), EPA will submit a 
report containing this rule and other required information to the U.S. 
Senate, the U.S. House of Representatives, and the Comptroller General 
of the United States prior to publication of the rule in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
