Environmental Protection Agency (EPA).
EPA is amending significant new use rules (SNURs) issued under the Toxic Substances Control Act (TSCA) for certain chemical substances, which were the subject of premanufacture notices (PMNs) and significant new use notices (SNUNs). As a result of EPA's review of SNUNs for these chemical substances and based on new and existing data, EPA is finalizing amendments to these SNURs. Specifically, this action amends the identified SNURs to allow certain new uses reported in the SNUNs without additional notification requirements and modify the significant new use notification requirements based on the actions and determinations for the SNUN submissions.
This rule is effective on December 28, 2020. For purposes of judicial review, this rule shall be promulgated at 1 p.m. (e.s.t.) on November 10, 2020.

A. What action is the Agency taking?
EPA is issuing amendments to the SNURs for certain chemical substances in 40 CFR part 721, subpart E. A SNUR for a chemical substance designates certain activities as a significant new use. Persons who intend to manufacture or process the chemical substance for the significant new use must notify EPA at least 90 days before commencing that activity. The required notification (i.e., a SNUN) initiates EPA's evaluation of the intended use within the applicable review period. Manufacture and processing for the significant new use may not commence until EPA has conducted a review of the notice, made an appropriate determination on the notice, and taken such actions as are required with that determination.
Previously, in the Federal Register of April 1, 2020 (85 FR 18173; FRL-10004-51), EPA proposed amendments to the SNURs for these chemical substances and established the record for these SNUR amendments in the docket under docket ID number EPA-HQ-OPPT-2019-0614. 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 (i.e., a SNUR) after considering all relevant factors, including those listed in TSCA section 5(a)(2). EPA may also amend a SNUR promulgated under TSCA section 5(a)(2). Procedures and criteria for modifying or revoking SNUR requirements appear at 40 CFR 721.185.
C. How do the general SNUR provisions apply to this action?
General provisions for SNURs appear in 40 CFR part 721, subpart A. These provisions describe persons subject to the final rule, recordkeeping requirements, exemptions to reporting requirements, and applicability of the rule to uses occurring before the effective date of the final 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 notice 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
A. Considerations for Significant New Use Determinations
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 whether and how to modify the significant new uses for the chemical substances that are the subject of these SNURs, and as described in the preamble to the proposed rule, EPA considered relevant information about the toxicity of the chemical substance, likely human exposures and environmental releases associated with possible uses, and the four TSCA section 5(a)(2) factors listed in this unit.
B. Procedures for Significant New Uses Claimed as 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 required to keep this information confidential. EPA promulgated a Start Printed Page 67998procedure 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 on Proposed Rule and EPA Responses
EPA received three public comments on the proposed amendments. The Agency's responses to these comments are provided in a separate Response to Public Comments document that is available in the docket for this rule. EPA made one change to the final rule amending 40 CFR 721.10663 based on one comment. Specifically, EPA added language used in previous SNURs for other carbon nanotube chemicals identifying criteria where SNUR requirements do not apply. EPA agrees with the commenter that when the chemical substance meets any of these criteria, there is no unreasonable risk from exposure to the substance.
V. Rationale of the Final Rule
These amendments are based on EPA's determination under 40 CFR 721.185(a)(3) following review of significant new use notices (SNUNs) for the chemical substances submitted to EPA. After reviewing the SNUNs, EPA concluded that there is no need to require additional notice from persons who propose to engage in identical or similar activities. In those instances where EPA expanded the scope of the significant new use, the Agency identified concerns during review of the SNUNs, as discussed in Unit IV. of the proposed rule, associated with certain potential new uses. In addition to considering the factors discussed in Unit IV. of the proposed rule, EPA determined that those uses could result in changes in the type or form of exposure to the chemical substance, increased exposures to the chemical substance, and/or changes in the reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of the chemical substance.
VI. Applicability of Rule to Uses Occurring Before Effective Date of the Final Rule
To establish a significant new use, EPA must determine that the use is not ongoing. EPA made this determination in issuing the original final rule for each chemical substance, and solicited additional comments on the proposed modifications to provide an opportunity for members of the public to indicate whether any of the uses which are not significant new uses under the current rules, but which would be regulated as “significant new uses” if the proposed rule is finalized, are ongoing. EPA received no comments that these uses were ongoing. Therefore, EPA concludes that the uses are not ongoing and designated April 1, 2020 (the date of publication of the proposed rule) as the cutoff date for determining whether the new use is ongoing.
In the unlikely event that a person began commercial manufacture or processing of the chemical substances for a significant new use identified as of the cutoff 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.
VII. Development and Submission of Information
EPA recognizes that TSCA section 5 generally 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 an applicable rule, order or consent agreement under TSCA section 4, or a TSCA section 5(b)(4) listing 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 addressed in this final rule. Descriptions are provided for informational purposes. The information identified in Unit IV. of the proposed rule will be potentially useful to EPA's evaluation of a chemical substance in the event that someone submits a SNUN for a significant new use pursuant to the SNURs addressed in this final rule. Companies who are considering submitting a SNUN are encouraged, but are not required, to develop the potentially useful 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 on 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 dialogue 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 identified in Unit IV. of the proposed rule 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 sections 5(e) or 5(f). EPA recommends that potential SNUN Start Printed Page 67999submitters contact EPA early enough to provide time for conducting 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; and
- Information on risks posed by the chemical substances compared to risks posed by potential substitutes.
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 under 40 CFR part 720, 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 721.25 and 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 rule. EPA's complete economic analysis is available in the docket under docket ID number EPA-HQ-OPPT-2019-0614.
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 modifies SNURs for several chemical substances that were the subject of PMNs and SNUNs. 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. Executive Order 13771: Reducing Regulations and Controlling Regulatory Costs
This action is not subject to Executive Order 13771 (82 FR 9339, February 3, 2017), because this action is not a significant regulatory action under Executive Order 12866.
C. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden under the PRA (44 U.S.C. 3501 et seq.). Burden is defined in 5 CFR 1320.3(b). The information collection activities associated with new chemical SNURs have already been approved under OMB control number 2070-0012 (EPA ICR No. 0574). This action does not impose any burden requiring additional OMB approval.
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. This listing of the OMB control numbers and their subsequent codification in the CFR satisfies the display requirements of PRA and OMB's implementing regulations at 5 CFR part 1320.
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.
D. 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 SNUR modifications will 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.
E. 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.).Start Printed Page 68000
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).
G. 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.
H. 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. EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that EPA has reason to believe may disproportionately affect children, per the definition of “covered regulatory action” in section 2-202 of the Executive Order.
I. 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.
J. National Technology Transfer and Advancement Act (NTTAA)
This action does not involve any technical standards and is therefore not subject to considerations under NTTAA section 12(d) (15 U.S.C. 272 note).
K. 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).
XI. 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 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).
