Significant New Use Rules on Certain 
Chemical Substances (19–4.B) 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : EPA is proposing significant 
new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 17 chemical substances which are the subject of premanufacture notices (PMNs). This action would require persons to notify EPA at least 90 days before commencing manufacture (defined by statute to include import) or processing of any of these 17 chemical substances for an activity that is designated as a significant new use by this proposed rule. This action would further require that persons not commence manufacture or processing for the significant new use until they have submitted a Significant New Use Notice, and EPA has conducted a review of the notice, made an appropriate determination on the notice under TSCA 5(a)(3), and has taken any risk management actions as are required as a result of that determination. 
DATES : Comments must be received on 
or before September 13, 2019.

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 (including 
importers) 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 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 these proposed SNURs would need to certify their compliance with the SNUR requirements should these proposed rules be finalized. The EPA policy in support of import certification appears at 40 CFR part 707, subpart B. In addition, pursuant to 40 CFR 721.20, any persons who export or intend to export a chemical substance that is the subject of this proposed rule on or after September 13, 2019 are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) and must comply with the export notification requirements in 40 CFR part 707, subpart D. 
B. What should I consider as I prepare 
my comments for EPA? 
1. Submitting CBI. Do not submit CBI 
to EPA through regulations.gov or email. 
Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD– ROM that you mail to EPA, mark the outside of the disk or CD–ROM as CBI and then identify electronically within the disk or CD–ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2. 
2. Tips for preparing your comments. 
When preparing and submitting your comments, see the commenting tips at 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 17 chemical 
substances which were the subjects of PMNs P–16–92, P–17–346, P–17–347/ 348/349/350/351/352, P–17–395, P–18– 35, P–18–103, P–18–155/156, P–18–286, P–18–392, P–19–29, and P–19–62. These proposed SNURs would require persons who intend to manufacture or process any of these chemical substances for an activity that is designated as a significant new use to notify EPA at least 90 days before commencing that activity. 
The record for the proposed SNURs 
on these chemicals was established as docket EPA–HQ–OPPT–2019–0442. That record includes information considered by the Agency in developing these proposed SNURs. 
B. What is the Agency’s authority for 
taking this action? 
Section 5(a)(2) of TSCA (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. Once EPA determines through rulemaking that a use of a chemical substance is a significant new use, TSCA section 5(a)(1)(B)(i) (15 U.S.C. 2604(a)(1)(B)(i)) requires persons to submit a significant new use notice (SNUN) to EPA at least 90 days before they manufacture or process the chemical substance for that use. TSCA prohibits such manufacturing or processing from commencing until EPA has conducted a review of the SNUN, made an appropriate determination on the SNUN, and taken such actions as are required in association with that determination (15 U.S.C. 2604(a)(1)(B)(ii)). 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. As described in Unit V., the general SNUR provisions are found at 40 CFR part 721, subpart A. 
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. 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) (15 U.S.C. 2604(a)(1)(A)). In particular, these requirements include the information submission requirements of TSCA sections 5(b) and 5(d)(1) (15 U.S.C. 2604(b) and 2604(d)(1)), the exemptions authorized by TSCA sections 5(h)(1), 5(h)(2), 5(h)(3), and 5(h)(5) and the regulations at 40 CFR part 720. Once EPA receives a SNUN, EPA must either determine that the use is not likely to present an unreasonable risk of injury under the conditions of 
use for the chemical substance or take such regulatory action as is associated with an alternative determination before the manufacture or processing for the significant new use can commence. If EPA determines that the 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 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 conditions of use of the substances, in the context of the four bulleted TSCA section 5(a)(2) factors listed in this unit. During its review of these chemicals, EPA identified certain conditions of use that are not intended by the submitters, but reasonably foreseen to occur. EPA is

proposing to designate those reasonably 
foreseen conditions of use as significant new uses. 
IV. Substances Subject to This Proposed 
Rule 
EPA is proposing significant new use 
and recordkeeping requirements for 17 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. 
•Information identified by EPA that 
would help characterize the potential health and/or environmental effects of the chemical substances if a manufacturer or processor is considering submitting a SNUN for a significant new use designated by the SNUR. 
This information may include testing 
not required to be conducted but which would help characterize the potential health and/or environmental effects of the PMN substance. Any recommendation for information identified by EPA was made based on EPA’s consideration of available screening-level data, if any, as well as other available information on appropriate testing for the chemical substance. Further, any such testing identified by EPA that includes testing on vertebrates was made after consideration of available toxicity information, computational toxicology and bioinformatics, and high- throughput screening methods and their prediction models. EPA also recognizes that whether testing/further information is needed will depend on the specific exposure and use scenario in the SNUN. EPA encourages all SNUN submitters to contact EPA to discuss any potential future testing. See Unit VII. for more information. 
•CFR citation assigned in the 
regulatory text section of these proposed rules. 
The regulatory text section of these 
proposed rules specifies the activities designated as significant new uses. Certain new uses, including production volume limits and other uses designated in the proposed rules, may be claimed as CBI. 
The chemical substances that are the 
subject of these proposed SNURs are undergoing premanufacture review. In addition to those conditions of use intended by the submitter, EPA has identified certain other reasonably foreseen conditions of use. EPA has preliminarily determined that the chemicals under their intended conditions of use are not likely to present an unreasonable risk. However, EPA has not assessed risks associated with the reasonably foreseen conditions of use for these chemicals. EPA is proposing to designate these reasonably foreseen and other potential conditions of use as significant new uses. As a result, those conditions of use are no longer reasonably foreseen to occur without first going through a separate, subsequent EPA review and determination process associated with a SNUN. 
The substances subject to these 
proposed rules are as follows: 
PMN Number: P–16–92 
Chemical name: Polymeric polyamine 
(generic). 
CAS number: Not available. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as industrial coatings, open non-dispersive use. Based on the physical/chemical properties of the PMN substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for irritation, corrosion, sensitization and lung effects (based on cationic binding to lung tissues), and toxicity to aquatic organisms at surface water concentrations exceeding 10 ppb, if the chemical substance is used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substance that EPA intends to assess before they occur include the following: 
•Use of the PMN substance for other 
than for the confidential use described in the PMN. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ these conditions of use. 
Potentially useful information: EPA 
has determined that certain information about the human health and environmental toxicity of the PMN substance may be potentially useful to characterize the health effects of the PMN substance 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 sensitization and environmental toxicity testing and pulmonary effects would help characterize the potential health and environmental effects of the PMN substance. 
CFR citation: 40 CFR 721.11330. PMN Number: P–17–346 
Chemical name: Triarylalkyl 
phosphonium halide salt (generic). 
CAS number: Not available. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as a destructive use. Based on the physical/chemical properties of the PMN substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for Acute toxicity, irritation/corrosion effects to the skin, eyes, and respiratory tract, systemic toxicity, and environmental toxicity if the chemical substance is used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substance that EPA intends to assess before they occur include the following: 
1. Use for other than the confidential 
uses identified in the PMN. 
2. Release of the PMN substance into 
the waters of the United States resulting in surface water concentrations exceeding 5 ppb. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ these conditions of use. 
Potentially useful information: EPA 
has determined that certain information about the human health and environmental toxicity of the PMN substance may be potentially useful to characterize the health and 
environmental effects of the PMN substance 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 acute toxicity, specific target organ toxicity, irritation, and environmental toxicity testing would help characterize the potential health and environmental effects of the PMN substance.

Basis for action: The PMNs state that 
the generic (non-confidential) use of the substances will be as an oilfield surfactant. Based on the physical/ chemical properties of the PMN substances and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for lung toxicity and toxicity to aquatic organisms, if the chemical substances are used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substances that EPA intends to assess before they occur include the following: 
1. Use of the PMN substances other 
than for the confidential use described in the PMNs. 
2. Any manufacture, processing or use 
of the PMN substances that results in inhalation exposure. 
3. Annual production volume 
exceeding 5,000 kilograms of the PMN substances in aggregate. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ these conditions of use. 
Potentially useful information: EPA 
has determined that certain information about the human health and environmental toxicity of the PMN substances 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 and environmental toxicity testing would help characterize the potential health and environmental effects of the PMN substances.

the generic (non-confidential) use of the 
substance will be as a water treatment additive. Based on the physical/ chemical properties of the PMN substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for developmental toxicity, neurotoxicity, carcinogenicity, and skin sensitization, and toxicity to aquatic organisms, if the chemical substance is used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substance that EPA intends to assess before they occur include the following: 
1. Use of the PMN substance other 
than for the confidential uses described in the PMN. 
2. Any manufacture, processing or use 
of the PMN substance that results in inhalation exposure.

Based on the physical/chemical properties of the PMN substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for irritation and developmental neurotoxicity effects, if the chemical substance is used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substance that EPA intends to assess before they occur include the following: 
1. Use of the PMN substance other 
than as a solvent in vapor degreasing/ vapor cleaning or additional confidential uses described in the PMN. 
2. Manufacture (including import), 
processing or use of the PMN substance without the transport container loading process described in the PMN. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ these conditions of use. 
Potentially useful information: EPA 
has determined that certain information about the human health toxicity of the PMN substance may be potentially useful to characterize the health effects of the PMN substance 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 skin irritation and developmental neurotoxicity testing would help characterize the potential health effects of the PMN substance.

PMN Number: P–18–392 
Chemical name: Heteromonocycle, 
alkenyl alkyl (generic). 
CAS number: Not available. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as an intermediate chemical. Based on the physical/ chemical properties of and test data on the PMN substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for irritation/ corrosion and carcinogenicity if the chemical substance is used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substance that EPA intends to assess before they occur include the following: 
•No use other than the confidential 
uses identified in the PMN. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ these conditions of use. 
Potentially useful information: EPA 
has determined that certain information about the human health toxicity of the PMN substance may be potentially useful to characterize the health effects of the PMN substance 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 absorption, skin and eye irritation/corrosion, and carcinogenicity testing would help characterize the potential health effects of the PMN substance.

PMN Number: P–19–29 
Chemical name: Phosphonium, 
tributylethyl-, diethyl phosphate (1:1). 
CAS number: 20445–94–7. 
Basis for action: The PMN states that 
the generic (non-confidential) use of the 
substance will be as a catalyst. Based on the physical/chemical properties of and available data on the PMN substance and Structure Activity Relationships (SAR) analysis of test data on analogous substances, EPA has identified concerns for irritation, corrosion, neurotoxicity, reproductive toxicity, liver toxicity, and toxicity to aquatic organisms at surface water concentrations exceeding 51 ppb, if the chemical substance is used in ways other than as intended by the PMN submitter. Other conditions of use of the PMN substance that EPA intends to assess before they occur include the following: 
1. Use of the PMN substance other 
than for the confidential uses described in the PMN. 
2. Release to the PMN substance into 
the waters of the United States resulting in surface water concentrations exceeding 51 ppb. 
The proposed SNUR would designate 
as a ‘‘significant new use’’ these conditions of use. 
Potentially useful information: EPA 
has determined that certain information about the human health and environmental fate of the PMN substance may be potentially useful to characterize the health effects of the PMN substance 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 irritation, specific target organ toxicity, neurotoxicity, and reproductive toxicity, and environmental fate testing would help characterize the potential health and environmental effects of the PMN substance.

CFR citation: 40 CFR 721.11345. 
V. Rationale and Objectives of the Proposed Rule 
A. Rationale 
During review of the PMNs submitted 
for the chemical substances that are the 
subject of these proposed SNURs and as further discussed in Unit IV, EPA identified certain other reasonably foreseen conditions of use, in addition to those conditions of use intended by the submitter. EPA has preliminarily determined that the chemical under the intended conditions of use is not likely to present an unreasonable risk. However, EPA has not assessed risks associated with the reasonably foreseen conditions of use. EPA is proposing to designate these conditions of use as significant new uses to ensure that they are no longer reasonably foreseen to occur without first going through a separate, subsequent EPA review and determination process associated with a SNUN. 
B. Objectives 
EPA is proposing SNURs for 17 
specific chemical substances which are 
undergoing premanufacture review because the Agency wants to achieve the following objectives with regard to the significant new uses that would be designated in this proposed rule: 
•EPA would 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. 
•EPA would be obligated to make a 
determination under TSCA section 5(a)(3) regarding the use described in the SNUN, under the conditions of use. The Agency will either determine under TSCA section 5(a)(3)(C) that the 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. •EPA would be able to complete its 
review and determination on each of the 
PMN substances, while deferring analysis on the significant new uses proposed in these rules unless and until the Agency receives a SNUN. 
Issuance of a proposed SNUR for a 
chemical substance does not signify that the chemical substance is listed on the TSCA Inventory. Guidance on how to determine if a chemical substance is on the TSCA Inventory is available on the internet at https://www.epa.gov/tsca- inventory. 
VI. Applicability of the Proposed Rules 
to Uses Occurring Before the Effective Date of the Final Rule 
To establish a significant new use, 
EPA must determine that the use is not ongoing. The chemical substances 
subject to this proposed rule were undergoing premanufacture review at the time of signature of this proposed rule and were not on the TSCA Inventory. In cases where EPA has not received a notice of commencement (NOC) and the chemical substance has not been added to the TSCA Inventory, no person may commence such activities without first submitting a PMN. Therefore, for the chemical substances subject to these proposed SNURs, EPA concludes that the proposed significant new uses are not ongoing. 
EPA designates August 1, 2019 (date 
of web posting) as the cutoff date for determining whether the new use is ongoing. The objective of EPA’s approach is to ensure that a person cannot defeat a SNUR by initiating a significant new use before the effective date of the final rule. 
Persons who begin commercial 
manufacture or processing of the chemical substances for a significant new use identified on or after that date would have to cease any such activity upon the effective date of the final rule. To resume their activities, these persons would have to first comply with all applicable SNUR notification requirements and EPA would have to take action under section 5 allowing manufacture or processing to proceed. In developing this proposed rule, EPA has recognized that, given EPA’s general practice of posting proposed rules on its website a week or more in advance of Federal Register publication, this objective could be thwarted even before Federal Register publication of the proposed rule. 
VII. Development and Submission of 
Information 
EPA recognizes that TSCA section 5 
does not require development of any particular new information (e.g., 
generating test data) before submission of a SNUN. There is an exception: If a person is required to submit information for a chemical substance pursuant to a rule, order or consent agreement under TSCA section 4 (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. lists potentially useful information for all SNURs listed here. Descriptions are provided for informational purposes. The potentially useful information identified in Unit IV. will be useful to EPA’s evaluation in the event that someone submits a SNUN for the significant new use. Companies who are considering submitting a SNUN are encouraged, but not required, to develop the information on the substance, which may assist with EPA’s analysis of the SNUN. 
EPA strongly encourages persons, 
before performing any testing, to consult with the Agency pertaining to protocol selection. Furthermore, pursuant to TSCA section 4(h), which pertains to reduction of testing in vertebrate animals, EPA encourages consultation with the Agency on the use of alternative test methods and strategies (also called New Approach Methodologies, or NAMs), if available, to generate the recommended test data. EPA encourages dialog with Agency representatives to help determine how best the submitter can meet both the data needs and the objective of TSCA 
section 4(h). 
The potentially useful information 
described in Unit IV. may not be the only means of providing information to evaluate the chemical substance associated with the significant new uses. However, submitting a SNUN without any test data may increase the likelihood that EPA will take action under TSCA section 5(e) or 5(f). EPA recommends that potential SNUN submitters contact EPA early enough so that they will be able to conduct the appropriate tests. 
SNUN submitters should be aware 
that EPA will be better able to evaluate SNUNs which provide detailed information on the following:

•Human exposure and 
environmental release that may result 
from the significant new use of the chemical substances. 
VIII. SNUN Submissions 
According to 40 CFR 721.1(c), persons 
submitting a SNUN must comply with 
the same notification requirements and EPA regulatory procedures as persons submitting a PMN, including submission of test data on health and environmental effects as described in 40 CFR 720.50. SNUNs must be submitted on EPA Form No. 7710–25, generated using e-PMN software, and submitted to the Agency in accordance with the procedures set forth in 40 CFR 720.40 and 721.25. E–PMN software is available electronically at https://www.epa.gov/reviewing-new-chemicals- under-toxic-substances-control-act-tsca. 
IX. Economic Analysis 
EPA has evaluated the potential costs 
of establishing SNUN requirements for 
potential manufacturers and processors of the chemical substances subject to this proposed rule. EPA’s complete economic analysis is available in the docket under docket ID number EPA– HQ–OPPT–2019–0263. 
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 8 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 Order 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011). 
B. Paperwork Reduction Act (PRA) 
According to the PRA, 44 U.S.C. 3501 
et seq., an Agency may not conduct or 
sponsor, and a person is not required to respond to a collection of information that requires OMB approval under PRA, unless it has been approved by OMB and displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in title 40 of the CFR, after appearing in the Federal Register, are listed in 40 CFR part 9, and included on the related collection instrument or form, if applicable. The information collection 
requirements related to this action have 
already been approved by OMB pursuant to PRA under OMB control number 2070–0012 (EPA ICR No. 574). This action does not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average between 30 and 170 hours per response. This burden estimate includes the time needed to review instructions, search existing data sources, gather and maintain the data needed, and complete, review, and submit the required SNUN. 
Send any comments about the 
accuracy of the burden estimate, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques, to the Director, Regulatory Support Division, Office of Mission Support (2822T), Environmental Protection Agency, 1200 Pennsylvania Ave. NW, Washington, DC 20460–0001. Please remember to include the OMB control number in any correspondence, but do not submit any completed forms to this address. 
C. Regulatory Flexibility Act (RFA) 
Pursuant to section 605(b) of the RFA, 
5 U.S.C. 601 et seq., 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, 12 in FY2016, 13 in FY2017, and 11 in FY2018, only a fraction of these were from small businesses. In addition, the Agency currently offers relief to qualifying small businesses by reducing the SNUN submission fee from $16,000 to $2,800. This lower fee reduces the total reporting and recordkeeping of cost of submitting a SNUN to about $10,116 for qualifying small firms. Therefore, the potential economic impacts of complying with this proposed SNUR are not expected to be significant or adversely impact a substantial number of small entities. In a SNUR that published in the Federal Register of June 2, 1997 (62 FR 29684) 
(FRL–5597–1), the Agency presented its general determination that final SNURs are not expected to have a significant economic impact on a substantial number of small entities, which was provided to the Chief Counsel for Advocacy of the Small Business Administration. 
D. Unfunded Mandates Reform Act 
(UMRA) 
Based on EPA’s experience with 
proposing and finalizing SNURs, State, local, and Tribal governments have not been impacted by these rulemakings, and EPA does not have any reasons to believe that any State, local, or Tribal government will be impacted by this proposed rule. As such, EPA has determined that this proposed rule does not impose any enforceable duty, contain any unfunded mandate, or otherwise have any effect on small governments subject to the requirements of UMRA sections 202, 203, 204, or 205 (2 U.S.C. 1531–1538 et seq.). 
E. Executive Order 13132: Federalism 
This action 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 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 proposed rule. 
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, 
VerDate Sep<11>2014 16:38 Aug 13, 2019 Jkt 247001 PO 00000 Frm 00081 Fmt 4702 Sfmt 4702 E:\FR\FM\14AUP1.SGM 14AUP1khammond on DSKBBV9HB2PROD with PROPOSALS40378 Federal Register / Vol. 84, No. 157 / Wednesday, August 14, 2019 / Proposed Rules 
1997), because this is not an 
economically significant regulatory action as defined by Executive Order 12866, and this action does not address environmental health or safety risks disproportionately affecting children. 
H. Executive Order 13211: Actions 
Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use 
This proposed rule is not subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001), because this action is not expected to affect energy supply, distribution, or use and because this action is not a significant regulatory action under Executive Order 12866. 
I. National Technology Transfer and 
Advancement Act (NTTAA) 
In addition, since this action does not 
involve any technical standards, NTTAA section 12(d), 15 U.S.C. 272 note, does not apply to this action. 
J. Executive Order 12898: Federal 
Actions To Address Environmental Justice in Minority Populations and Low-Income Populations 
This action does not entail special 
considerations of environmental justice related issues as delineated by Executive Order 12898 (59 FR 7629, February 16, 1994).
