III. Statutory and Executive Order 
Reviews 
Under the CAA, the Administrator is 
required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA’s role is to approve state choices, if they meet the criteria of the Act. Accordingly, this proposed action merely proposes to approve state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action: 
•Is not a ‘‘significant regulatory 
action’’ subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); 
•Is not an Executive Order 13771 (82 
FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866; 
•Does not impose an information 
collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); 
•Is certified as not having a 
significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); 
•Does not contain any unfunded 
mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); 
•Does not have Federalism 
implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); 
•Is not an economically significant 
regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); 
•Is not a significant regulatory action 
subject to Executive Order 13211 (66 FR 28355, May 22, 2001); 
•Is not subject to requirements of 
section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and 
•Does not provide the EPA with the 
discretionary authority to address disproportionate human health or environmental effects with practical, appropriate, and legally permissible methods under Executive Order 12898 (59 FR 7629, February 16, 1994). 
In addition, the SIP is not approved 
to apply on any Indian reservation land or in any other area where the EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

Significant New Use Rules on Certain 
Chemical Substances (19–4.F) 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : EPA is proposing significant 
new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 26 chemical substances which were the subject of premanufacture notices (PMNs). Five of these chemical substances are subject to Orders issued by EPA pursuant to TSCA, and the remaining 21 of these chemical substances received a ‘‘not likely to present an unreasonable risk’’ determination pursuant to TSCA. This action would require persons who intend to manufacture (defined by statute to include import) or process any of these 26 chemical substances for an activity that is proposed as a significant new use to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA’s evaluation of the use, under the conditions of use for that chemical substance, within the applicable review period. Persons may not commence 
manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required by that determination. 
DATES : Comments must be received on 
or before December 4, 2019.

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 
VerDate Sep<11>2014 17:22 Nov 01, 2019 Jkt 250001 PO 00000 Frm 00021 Fmt 4702 Sfmt 4702 E:\FR\FM\04NOP1.SGM 04NOP159336 Federal Register / Vol. 84, No. 213 / Monday, November 4, 2019 / Proposed Rules 
(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 certification requirements 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 final 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 proposed rule on or after December 4, 2019 are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (see 40 CFR 721.20), and must comply with the export notification requirements in 40 CFR part 707, subpart D. 
B. What should I consider as I prepare 
my comments for EPA? 
1. Submitting CBI. Do not submit this 
information to EPA through regulations.gov or email. Clearly mark 
the part or all of the information that you claim to be CBI. For CBI information in a disk or CD–ROM that you mail to EPA, mark the outside of the 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 http://www.epa.gov/dockets/ comments.html. 
II. Background A. What action is the Agency taking? 
EPA is proposing these SNURs under 
TSCA section 5(a)(2) for chemical 
substances that were the subject of PMNs. These proposed SNURs would require persons to notify EPA at least 90 days before commencing the manufacture or processing of a chemical substance for any activity proposed as a 
significant new use. Receipt of such notices would allow EPA to assess risks and, if appropriate, to regulate the significant new use before it may occur. Additional background regarding SNURs is more fully set out in the preamble to EPA’s first direct final SNUR published in the Federal Register issue of April 24, 1990 (55 FR 17376). Consult that preamble for further general information on the objectives, rationale, and procedures for SNURs and on the basis for significant new use designations, including provisions for developing test data. 
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 proposed rule, recordkeeping requirements, and 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 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 section 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 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. In the case of a determination other than not likely to present unreasonable risk, the applicable review period must also expire before manufacturing or processing for the new use may commence. If EPA determines that the use is not likely to present an unreasonable risk, EPA is required under TSCA section 5(g) to make public, and submit for publication in the Federal Register, a statement of EPA’s findings. 
III. Significant New Use Determination 
TSCA section 5(a)(2) states that EPA’s 
determination that a use of a chemical 
substance is a significant new use must be made after consideration of all relevant factors, including: 
•The projected volume of 
manufacturing and processing of a chemical substance. 
•The extent to which a use changes 
the type or form of exposure of human beings or the environment to a chemical substance. 
•The extent to which a use increases 
the magnitude and duration of exposure of human beings or the environment to a chemical substance. 
•The reasonably anticipated manner 
and methods of manufacturing, processing, distribution in commerce, and disposal of a chemical substance. 
In determining significant new uses 
for the 26 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 addition to the factors in TSCA section 5(a)(2). Consistent with TSCA section 5(f)(4), for the five chemical substances subject to an order under TSCA section 5(e), EPA is proposing to identify any use not conforming to the restrictions of the order as a significant new use. For the 21 chemical substances that EPA has determined ‘‘not likely’’ to present an unreasonable risk under the conditions of use, EPA is proposing to identify other circumstances that, while not reasonably foreseen, would warrant further EPA review before manufacture or processing for such a use is commenced. 
IV. Substances Subject to This Proposed 
Rule 
EPA is proposing significant new use 
and recordkeeping requirements for 26 chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides 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 or basis for the 
TSCA 5(e) Order. 
•Potentially Useful Information. This 
is information identified by EPA that 
VerDate Sep<11>2014 17:22 Nov 01, 2019 Jkt 250001 PO 00000 Frm 00022 Fmt 4702 Sfmt 4702 E:\FR\FM\04NOP1.SGM 04NOP159337 Federal Register / Vol. 84, No. 213 / Monday, November 4, 2019 / Proposed Rules 
would help characterize the potential 
health and/or environmental effects of the chemical substance in support of a request by the PMN submitter to modify the Order, or if a manufacturer or 
processor is considering submitting a SNUN for a significant new use designated by the SNUR. 
•CFR citation assigned in the 
regulatory text section of the proposed rule. The regulatory text section of each proposed rule specifies the activities that would be designated as significant new uses. Certain new uses, including exceedance of production volume limits (i.e., limits on manufacture volume) and 
other uses designated in this proposed rule, may be claimed as CBI. 
These proposed rules include five 
PMN substances that are subject to Orders issued under TSCA section 5(e)(1)(A), as required by the determinations made under section 5(a)(3)(B). Those Orders require protective measures to limit exposures or otherwise mitigate the potential unreasonable risk. The proposed SNURs would identify as significant new uses any manufacturing, processing, use, distribution in commerce, or disposal that does not conform to the restrictions imposed by the underlying Orders, consistent with TSCA section 5(f)(4). 
These proposed rules also include 21 
PMN substances that received ‘‘not likely to present an unreasonable risk’’ determination in TSCA section 5(a)(3)(c). However, during the course of these reviews, EPA identified concerns for certain health and/or environmental risks if the chemicals were not used following the limitations identified by the submitters in the notices, but the TSCA section 5(a)(3)(C) determinations did not deem such uses as reasonably foreseen. The proposed SNURs would identify as significant new uses any manufacturing, processing, use, distribution in commerce, or disposal that does not conform to those same limitations. 
The chemicals subject to these 
proposed SNURs are as follows: 
PMN Number: P–16–548 
Chemical Name: Triarylsulfonium salt 
(generic). 
CAS Number: Not available. 
Effective date of TSCA section 5(e) 
Order: July 22, 2019. 
Basis for TSCA section 5(e) Order: 
The PMN states that the generic (non- 
confidential) use of the PMN substance will be as a resin catalyst. Based on physical/chemical properties of the PMN substance (as described in the New Chemical Program’s PBT category at 64 FR 60194; November 1999), the PMN substance is a potentially persistent, bioaccumulative, and toxic 
(PBT) chemical. EPA estimates that that PMN substance will persist in the environment for more than 2 months and estimates a bioaccumulation factor of greater than or equal to 1,000. Based on comparison to structurally analogous chemical substances, the estimated physical/chemical properties of the PMN, and test data for the PMN substance, EPA has identified concerns for eye irritation, systemic, developmental, blood, and reproductive effects. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation, the substance may present an unreasonable risk of injury to human health and the environment. To protect against these risks, the Order requires: 
1. Refraining from domestic 
manufacture in the United States (i.e., import only); 
2. Use of the PMN substance only for 
the confidential use specified in the Order; 
3. No manufacture (including import) 
of the PMN substance beyond the confidential annual manufacture volume specified in the Order; 
4. Refraining from processing or using 
the PMN substance in any manner that generates a mist, vapor, or aerosol; and 
5. No release of the PMN substance 
into the waters of the United States. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information about the human health effects of the PMN substance may be potentially useful in support of a request by the PMN submitter to modify the TSCA section 5(e) Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has determined that the results of specific target organ toxicity and reproductive/developmental toxicity testing would help characterize the potential health effects of the PMN substance. Although the TSCA section 5(e) Order does not require this information, the TSCA section 5(e) Order’s restrictions remain in effect until the TSCA section 5(e) Order is modified or revoked by EPA based on submission of this or other relevant 
information.

CAS Numbers: Not available. 
Basis for action: The PMNs state that 
the generic (non-confidential) use of the 
substances will be as additives for electrocoat. Based on the estimated physical/chemical properties of the PMN substances, comparison with structurally analogous substances, and Structural Activity Relationships (SAR) analysis on analogous polycationic polymers, EPA has identified concerns for lung effects, nasal epithelial damage, skin and eye irritation, and aquatic toxicity if the chemical substances are not used following the limitations noted. The conditions of use of the PMN substances as described in the PMNs include the following protective measures: 
1. No modification of the 
manufacturing, processing, or use of the PMN substances that result in the 
VerDate Sep<11>2014 17:22 Nov 01, 2019 Jkt 250001 PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 E:\FR\FM\04NOP1.SGM 04NOP159338 Federal Register / Vol. 84, No. 213 / Monday, November 4, 2019 / Proposed Rules 
generation of a dust, mist, or aerosol; 
and 
2. No release of a manufacturing, 
processing, or use stream associated with any use of the PMN substance into the waters of the United States 
exceeding a surface water concentration of 78 ppb. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information may be potentially useful to characterize the health and environmental effects of the PMN substances 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 pulmonary effects, skin irritation/corrosion, eye damage, and acute aquatic toxicity testing would help characterize the potential health effects of the PMN substances.

CAS numbers: Not available. 
Effective date of TSCA section 5(e) 
Order: June 10, 2019. 
Basis for TSCA section 5(e) Order: 
The PMNs state that the use of P–17– 
398 and P–17–399 will be as a refinery feedstock or fuel blending additive, the generic use of P–18–1 will be as an additive, and the use of P–18–28 will be as a chemical feedstock. Based on the physical/chemical properties of the PMN substances and comparison to structurally analogous chemical substances, EPA has identified concerns for neurological impairment, and hematological effects including aplastic anemia and acute myelogenous leukemia for PMN substance P–18–28. There is concern for lung effects for P– 18–1, if respirable, based on the respirable, poorly soluble particles category. Based on SAR analysis on analogous substances, EPA predicts toxicity to aquatic organisms may occur at concentrations that exceed 1 ppb for P–17–398 and P–17–399, and 15 ppb for P–18–28. The Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a finding that in the absence of sufficient information to permit a reasoned evaluation, the substances may present an unreasonable risk of injury to human health and the environment. The Order was also issued under TSCA sections 5(a)(3)(B)(ii)(II) and 5(e)(1)(A)(ii)(II), based on a finding that the substances are or will be produced in substantial quantities and that the substances either enter or may reasonably be anticipated to enter the environment in substantial quantities, or there is or may be significant (or substantial) human exposure to the substances. To protect against these risks, the Order requires: 
1. Refraining from manufacturing, 
processing, or using P–17–398 and P– 17–399 other than as a refinery feedstock or a fuel blending additive and refrain from manufacturing, processing, and using P–18–28 other than as a chemical feedstock or a fuel blending additive; 
2. Manufacture of P–18–1 via the 
enclosed manufacturing process described in the PMN; and 
3. Manufacture of P–18–1 according 
to the particle sizes described in the PMN: 1% or less of the particles at less than 75 microns. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ the absence of these protective measures. 
Potentially useful information: EPA 
has determined that certain information about the human health and environmental effects of the PMN substances may be potentially useful in support of a request by the PMN submitter to modify the TSCA section 5(e) Order, or if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this SNUR. EPA has determined that the results of additional particle size characterization testing for P–18–1 and acute and chronic aquatic toxicity testing for P– 17–398, P–17–399, and P–18–28 would help EPA determine the potential human and environmental effects of the PMN substances. Although the TSCA section 5(e) Order does not require this information, the Order’s restrictions remain in effect until the Order is modified or revoked by EPA based on submission of this or other relevant information.

The conditions of use of the PMN substance as described in the PMN include the following protective measures: 
1. No release of a manufacturing,

CFR Citation: 40 CFR 721.11411. 
V. Rationale and Objectives of the Proposed Rule 
A. Rationale 
During review of the PMNs submitted 
for the chemical substances that are 
subject to these proposed SNURs, EPA concluded that for five chemical substances regulation was warranted under TSCA section 5(e), pending the development of information sufficient to make reasoned evaluations of the health or environmental effects of the chemical substances. The basis for such findings is outlined in Unit IV. Based on these findings, TSCA section 5(e) Orders requiring the use of appropriate exposure controls were negotiated with the PMN submitters. As a general matter, EPA believes it is necessary to follow TSCA section 5(e) Orders with a SNUR that identifies the absence of those protective measures as Significant New Uses to ensure that all manufacturers and processors—not just the original submitter—are held to the same standard. 
During review of the other 21 
chemical substances that are the subject of these SNURs and as further discussed in Unit IV, EPA identified certain circumstances that raised potential risk concerns. EPA determined that deviations from the limitations identified in the submissions could result in changes in the type or form of exposure to the chemical substances and/or increased exposures to the chemical substances and/or changes in the reasonably anticipated manner and methods of manufacturing, processing, distribution in commerce, and disposal of the chemical substances, and therefore warranted SNURs. The SNURs would identify as significant new uses any manufacturing, processing, use, distribution in commerce, or disposal that does not conform to the certain limitations in the submission. 
B. Objectives 
EPA is proposing these SNURs for 
specific chemical substances which 
have undergone premanufacture review because the Agency wants: 
•To 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 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 either determine that the 
prospective manufacture or processing is not likely to present an unreasonable risk, or to take necessary regulatory action associated with any other determination, before the described significant new use of the chemical substance occurs. 
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. 
VI. Applicability of the Proposed 
Significant New Use Designation 
To establish a significant new use, 
EPA must determine that the use is not ongoing. The chemical substances subject to this proposed rule have undergone premanufacture review. In cases where EPA has not received a notice of commencement (NOC) and the chemical substance has not been added to the TSCA Inventory, no person may commence such activities without first submitting a PMN. Therefore, for chemical substances for which an NOC has not been submitted EPA concludes that the designated significant new uses are not ongoing. 
When chemical substances identified 
in this proposed rule are added to the TSCA Inventory, EPA recognizes that, before the rule is effective, other persons might engage in a use that has been identified as a significant new use. However, TSCA section 5(e) Orders have been issued for five of the 26 chemical substances, and the PMN submitters are prohibited by the TSCA section 5(e) Orders from undertaking activities which would be designated as significant new uses. The identities of 21 of the 26 chemical substances subject to this proposed rule have been claimed as confidential (per 40 CFR 720.85) for a chemical substance covered by this action. Based on this, the Agency believes that it is highly unlikely that any of the significant new uses described in the regulatory text of this proposed rule are ongoing. 
Therefore, EPA designates November 
4, 2019 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 as of that date would have to cease any such activity upon the effective date of the final rule. To resume their activities, these persons would have to first comply with all applicable SNUR notification requirements and wait until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required with that determination. 
VII. Development and Submission of 
Information 
EPA recognizes that TSCA section 5 
does not require developing any particular new information (e.g., generating test data) before submission of a SNUN. There is an exception: development of test data is required where the chemical substance subject to the SNUR is also subject to a rule, order or consent agreement under TSCA section 4 (see TSCA section 5(b)(1)). 
In the absence of a TSCA section 4 
test rule 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 identified by EPA that would help characterize the potential health and/or environmental effects of the PMN/SNUN substance for all of the listed SNURs. EPA recognizes that the 2016 Lautenberg Amendments have led to modifications in our approach to 
testing requirements, including an increased consideration of alternatives to vertebrate testing. Descriptions of tests/information needs are provided for informational purposes only and EPA strongly encourages persons, before performing any testing, to consult with the Agency pertaining to protocol selection. 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 potentially useful information. 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). To access the OCSPP test guidelines referenced in this document electronically, please go to http://www.epa.gov/ocspp and select ‘‘Test 
Methods and Guidelines.’’ The 
Organisation for Economic Co-operation and Development test guidelines are available from the OECD Bookshop at http://www.oecdbookshop.org or 
SourceOECD at http://www.sourceoecd.org. 
The potentially useful information 
listed in Unit IV. may not be the only 
means of addressing the potential risks of the chemical substance. 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 http://www.epa.gov/opptintr/newchems. 
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 under docket ID number EPA– HQ–OPPT–2019–0494. 
X. Statutory and Executive Order 
Reviews 
Additional information about these 
statutes and Executive Orders can be found at https://www.epa.gov/laws- regulations-and-executive-orders. A. Executive Order 12866: Regulatory 
Planning and Review and Executive Order 13563: Improving Regulations and Regulatory Review 
This proposed rule would establish 
SNURs for several new chemical substances that were the subject of PMNs and TSCA section 5(e) Orders. 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 the PRA, unless it has been approved by OMB and displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in title 40 of the CFR, after appearing in the Federal Register, are listed in 40 CFR part 9, and included on the related collection instrument or form, if applicable. 
The information collection activities 
in this proposed rule have already been approved by OMB pursuant to the 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.), the Agency hereby 
certifies 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, 10 in FY2016, 14 in FY2017, and 18 in FY2018 and only a fraction of these were from small businesses. In addition, the Agency currently offers 
relief to qualifying small businesses by reducing the SNUN submission fee from $16,000 to $2,800. This lower fee reduces the total reporting and recordkeeping of cost of submitting a SNUN to about $10,116 for qualifying small firms. Therefore, the potential economic impacts of complying with this proposed SNUR are not expected to be significant or adversely impact a substantial number of small entities. In a SNUR that published in the Federal Register of June 2, 1997 (62 FR 29684) 
(FRL–5597–1), the Agency presented its general determination that final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration. 
D. Unfunded Mandates Reform Act 
(UMRA) 
Based on EPA’s experience with 
proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reasons to believe that any State, local, or Tribal government will be impacted by this action. As such, EPA has determined that this proposed rule would not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1501 et seq.).

E. Executive Order 11632: Federalism 
This proposed rule would not have a 
substantial direct effect on States, on the 
relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). 
F. Executive Order 13175: Consultation 
and Coordination With Indian Tribal Governments 
This proposed rule would not have 
Tribal implications because it is not expected to have substantial direct 
effects on Indian Tribes. This proposed rule would not significantly nor uniquely affect the communities of Indian Tribal governments, nor would it involve or impose any requirements that affect Indian Tribes. Accordingly, the requirements of Executive Order 13175 (65 FR 67249, November 9, 2000), do not apply to this action. 
G. Executive Order 13045: Protection of 
Children From Environmental Health Risks and Safety Risks 
This proposed rule is not subject to 
Executive Order 13045 (62 FR 19885, April 23, 1997), because this is not an economically significant regulatory action as defined by Executive Order 12866, and this action does not address environmental health or safety risks disproportionately affecting children. 
H. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This proposed rule is not subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001), because this proposed rule is not expected to affect energy supply, distribution, or use and because this proposed rule is not a significant regulatory action under Executive Order 12866. 
I. National Technology Transfer and 
Advancement Act (NTTAA) 
In addition, since this proposed rule 
would 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 proposed rule does not entail 
special considerations of environmental justice related issues as delineated by Executive Order 12898 (59 FR 7629, February 16, 1994). List of Subjects in 40 CFR Part 721
