particular, the Act addresses actions 
that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 (adjusted for inflation) or more in any one year. Though this rule will not result in such an expenditure, 
we do discuss the effects of this rule elsewhere in this preamble. 
F. Environment 
We have analyzed this rule under 
Department of Homeland Security 
Directive 023–01, Rev. 1, associated implementing instructions, and Environmental Planning COMDTINST 5090.1 (series), which guide the Coast Guard in complying with the National Environmental Policy Act of 1969 (42 U.S.C. 4321–4370f), and have determined that this action is one of a category of actions that do not individually or cumulatively have a significant effect on the human environment. This rule involves a safety zone lasting only 110 total hours that will prohibit entry within a portion of the Potomac River. It is categorically excluded from further review under paragraph L60(a) of Appendix A, Table 1 of DHS Instruction Manual 023–01– 001–01, Rev. 1. A Record of Environmental Consideration supporting this determination is available in the docket. For instructions on locating the docket, see the 
ADDRESSES section of this preamble.

Significant New Use Rules on Certain 
Chemical Substances (20–4.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 were the subject of premanufacture notices (PMNs). This action requires persons to notify EPA 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. This action further requires 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 : This rule is effective on May 21, 
2021. For purposes of judicial review, this rule shall be promulgated at 1 p.m. (e.s.t.) on April 5, 2021.

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. This action may also affect certain entities through pre-existing import certification and export notification rules under TSCA, which would include the SNUR requirements. 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 rule 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.

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–18– 59, P–18–60, and P–18–381. 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 
April 17, 2020 (85 FR 21366) (FRL– 10007–50), EPA proposed SNURs for these chemical substances. More information on the specific chemical substances subject to this final rule can be found in the Federal Register document proposing the SNURs. The 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 on the proposed rules, as described in Unit IV. 
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 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). 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), 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 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 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 A. Determination Factors 
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 designating those reasonably foreseen conditions of use as well as certain other circumstances of use as significant new uses. 
B. Procedures for Significant New Uses 
Claimed as Confidential Business Information (CBI) 
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 
VerDate Sep<11>2014 16:10 Mar 19, 2021 Jkt 253001 PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 E:\FR\FM\22MRR1.SGM 22MRR1jbell on DSKJLSW7X2PROD with RULES15098 Federal Register / Vol. 86, No. 53 / Monday, March 22, 2021 / Rules and Regulations 
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) and has referenced it to apply to other SNURs. 
Under these procedures a 
manufacturer or processor may request EPA to determine whether a specific 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. 
IV. Public Comments 
EPA received public comments from 
two identifying entities on the proposed 
rule. The Agency’s responses are described in a separate Response to Public Comments document contained in the public docket for this rulemaking. EPA made one change to a final rule as described in the document. EPA also received one anonymous comment. It was general in nature and did not pertain to the proposed rule; therefore, no response is required. 
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, 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 this final rule. 
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. 
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 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 designating 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 issuing 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 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. 
•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 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. 
VII. Applicability of the 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 rule were undergoing premanufacture review at the time of signature of the 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 SNURs EPA concluded at the time of signature of the proposed rule that the designated significant new uses were not ongoing. 
EPA designated April 2, 2020 (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 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 began commercial 
manufacture or processing of the chemical substances for a significant new use identified on or after that date will 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 TSCA section 5 allowing manufacture or processing to proceed. 
VIII. Development and Submission of 
Information 
EPA recognizes that TSCA section 5 
does not require development of any 
VerDate Sep<11>2014 16:10 Mar 19, 2021 Jkt 253001 PO 00000 Frm 00030 Fmt 4700 Sfmt 4700 E:\FR\FM\22MRR1.SGM 22MRR1jbell on DSKJLSW7X2PROD with RULES15099 Federal Register / Vol. 86, No. 53 / Monday, March 22, 2021 / Rules and Regulations 
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. of the proposed rule lists potentially useful information for all SNURs listed here. Descriptions are 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. 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 election. 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 which provide detailed information on the following: •Human exposure and 
environmental release that may result from the significant new use of the chemical substances. 
IX. 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. 
X. 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 for this rulemaking. 
XI. 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 
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. 
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 RFA section 605(b), 5 
U.S.C. 601 et seq., I hereby certify 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, 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 
VerDate Sep<11>2014 16:10 Mar 19, 2021 Jkt 253001 PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 E:\FR\FM\22MRR1.SGM 22MRR1jbell on DSKJLSW7X2PROD with RULES15100 Federal Register / Vol. 86, No. 53 / Monday, March 22, 2021 / Rules and Regulations 
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 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. 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 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 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). 
K. Congressional Review Act (CRA) 
This action is subject to the CRA (5 
U.S.C. 801 et seq.), and EPA will submit 
a rule report containing this rule and 
other required information to each House of the Congress and to the Comptroller General of the United States. This action is not a ‘‘major rule’’ as defined by 5 U.S.C. 804(2).

ACTION : Final rule. 
SUMMARY : The Environmental Protection 
Agency (EPA) is taking final action to withdraw the remaining portion of a Federal Implementation Plan (FIP) for Arkansas that was published in the Federal Register on September 27, 2016, which addressed certain regional haze obligations for the first implementation period for the Domtar Ashdown Mill. Specifically, this remaining portion of the FIP we are withdrawing contains best available retrofit technology (BART) requirements for sulfur dioxide (SO
2) and nitrogen oxide (NO X) for 
Domtar Ashdown Mill Power Boiler No. 1; and SO
2, NO X, and particulate matter 
(PM) BART requirements for Power Boiler No. 2. These portions of the FIP are being replaced by a revision to the Arkansas State Implementation Plan (SIP) containing SO
2, NO X, and PM 10 
BART alternative emission limitations that we are taking final action to approve in a separate rulemaking that is also being published in this issue of the Federal Register. 
DATES : This final rule will be effective 
April 21, 2021.
