Modification of Significant New Uses 
of Certain Chemical Substances 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : EPA is proposing to amend 
the significant new use rules (SNURs) for chemical substances, which were the subject of a premanufacture notice (PMN) and a significant new use notice (SNUN). This action would amend the 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. EPA is proposing this amendment based on review of new and existing data for the chemical substances. 
DATES : Comments must be received on 
or before May 1, 2020.

SUPPLEMENTARY INFORMATION : 
I. General Information 
A. Does this action apply to me? 
You may be potentially affected by 
this action if you manufacture, process, 
or use the chemical substances contained in this 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 the 
chemical substance (NAICS codes 325 and 324110), e.g., chemical 
manufacturing and petroleum refineries. 
This proposed rule may 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 and must certify that the shipment of the chemical substance complies with all applicable rules and orders under TSCA. Importers of chemicals subject to a SNUR must certify their compliance with the SNUR requirements. Any person who exports or intends to export the chemical substance that is the subject of a final rule are subject to the export notification provisions of TSCA section 12(b) (15 U.S.C. 2611(b)) (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 amendments to the 
SNURs for 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 would initiate EPA’s evaluation of the intended use within the applicable review period. Manufacture and processing for the significant new use would be unable to commence until EPA conducted a review of the notice, made an appropriate determination on the notice, and took such actions as are required with that determination. 
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 and may issue or modify a TSCA section 5(e) Order and/or amend the SNUR promulgated under TSCA section 5(a)(2). Procedures and criteria for modifying or revoking SNUR requirements appear at 40 CFR 721.185. 
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 whether and how to 
amend the significant new uses for the chemical substances that are the subject of these SNURs 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. 
IV. Substances Subject to This Proposed 
Significant New Use Rule Amendment and Proposed Changes 
EPA is proposing to amend the 
significant new use and recordkeeping requirements for chemical substances in 40 CFR part 721, subpart E. In this unit, EPA provides the following information for each chemical substance: 
•PMN number and SNUN number. 
•Chemical name (generic name, if 
the specific name is claimed as CBI). 
•Chemical Abstracts Service (CAS) 
number (if assigned for non-confidential chemical identities). 
•Federal Register publication date 
and reference for the final SNUR previously issued. 
•Basis for the Proposed Amendment. 
•Potentially Useful Information. This 
is information identified by EPA that 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 TSCA 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 this proposed rule. 
PMN P–95–169; SNUN S–08–7; SNUN 
S–14–1; and SNUN S–17–10 
Chemical name: 2-Propen-1-one, 1-(4- 
morpholinyl)-. 
CAS number: 5117–12–4. 
Federal Register publication date and 
reference: Jan. 5, 2000 (65 FR 354) 
(FRL–6055–2), amended May 13, 2011 
(76 FR 27910) (FRL–8871–5), and amended June 30, 2015, (80 FR 37165) (FRL–9928–93). 
Basis for the modified significant new 
use rule: P–95–169 is used as a diluent for ultraviolet and electron beam curable resins for coatings, inks, and curable adhesives, S–14–1 is used as a monomer in ultraviolet ink jet applications and S–08–7 is used in energy production. The proposed SNUR modification of April 9, 2015, (80 FR 19037) (FRL–9924–10) contains the basis of the current SNUR codified at 40 CFR 721.5185. 
On June 12, 2017, EPA received a 
SNUN (S–17–10) involving the chemical 
substance for use as a monomer for use in stereolithography. The 90-day review period for the SNUN expired on February 6, 2018 and a TSCA section 5(e) Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a determination that the use may present an unreasonable risk of injury to human health and the environment. EPA identified concerns, based on acute toxicity, neurotoxicity, eye irritation, sensitization, liver toxicity, and aquatic toxicity test data for the chemical substance. In addition to the dermal protection, hazard communication, use, and water release notification requirements under the SNUR, the TSCA section 5(e) Order for S–17–10 required respirators to prevent inhalation exposure during the use of the chemical substance as a monomer in stereolithography. The proposed amendment would remove the use described in the SNUN from the scope of the significant new use, except where that use does not include the protective measures described in the TSCA section 5(e) Order for S–17–10. 
Potentially Useful Information: 
Certain information may be potentially useful to characterize the health and environmental effects of the chemical substance in support of a request 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 proposed SNUR. The results of specific organ toxicity and aquatic toxicity testing would help 
characterize the potential health and environmental effects of the chemical substance

CAS numbers: Not Available. 
Federal Register publication date and 
reference: Apr. 27, 2012, (77 FR 25236) 
(FRL– 9343–4). 
Basis for the modified significant new 
use rule: P–10–136 states that the 
chemical substances will be used as a monomer for acryl-based ultra-violet (UV)-curing coatings, inks, and adhesives. A SNUR was issued based on meeting the concern criteria at 40 CFR 721.170(b)(3)(i) and (b)(4)(i). EPA identified concerns for systemic toxicity, mutagenic effects, dermal sensitization and neurotoxicity, based on test data on the PMN substances. The SNUR required notification for domestic manufacture; for use other than as a monomer for acryl-based ultra-violet (UV)-curing coatings, inks, and adhesives; and for manufacturing, processing or use resulting in releases to surface waters exceeding 2 ppb. 
On August 16, 2018, EPA received S– 
18–5 for the generic (non-confidential) use as a monomer for industrial adhesives, coatings and inks. The 90- day review period expired on September 25, 2019. Based on the activities described in the SNUN, EPA determined under TSCA section 5(a)(3)(C) that the use is not likely to present an unreasonable risk. The modified SNUR would retain the existing notification requirements and remove the new use described in S–18– 5 from the scope of the significant new use. 
Potentially Useful Information: 
Certain information may be potentially useful to characterize the health and environmental effects of the chemical substances if a manufacturer or processor is considering submitting a SNUN for a significant new use that would be designated by this proposed SNUR. The results of specific target organ toxicity and aquatic toxicity testing would help characterize the potential health and environmental effects of the chemical substances.

PMN P–12–44; SNUN S–18–4; and 
SNUN S–19–5 
Chemical name: Functionalized 
multi-walled carbon nanotubes (generic). 
CAS number: None. 
Federal Register publication date and 
reference: May 9, 2013, (78 FR 27056) 
(FRL–9384–8). 
Basis for the modified significant new 
use rule: The generic (non-confidential) 
use for P–12–44 is an additive for rubber and batteries. The SNUR was issued based on meeting the concern criteria at 40 CFR 721.170(b)(3)(ii) and (b)(4)(ii). EPA identified concerns for lung effects to workers exposed to the PMN substance and for sublethal effects in fish at levels at 100 ppb. The SNUR required notification if the chemical substance was used other than for the confidential use described in the PMN, for manufacturing, processing or use as a powder, and for manufacturing, processing or use resulting in releases to surface waters. 
On May 14, 2018, EPA received a 
SNUN, S–18–4 for the chemical substance for use as a chemical additive in epoxy compounds for transportation, marine and industrial coatings, paints and manufactured goods. The 90-day review period for the SNUN expired on February 22, 2019. Based on the activities described in the SNUN, an Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on determinations under sections 5(a)(3)(B)(i) and 5(e)(1)(A)(i) of TSCA that the use may present an unreasonable risk of injury to human health, and the information available to the Agency is insufficient to permit a reasoned evaluation of the environmental effects. EPA identified concerns for lung effects, carcinogenicity, immunotoxicity, and thymus toxicity. 
Due to potential worker exposures, 
the TSCA Order for S–18–4 allows the use of the chemical substance as a chemical additive for use in epoxy compounds for transportation, marine and industrial coatings, paints and manufactured goods and requires personal protective equipment including respirators to prevent dermal and inhalation exposure. The TSCA Order also retains the same requirements as the SNUR for no water release, for no manufacturing, processing or use as a powder, and allowing the confidential use described in PMN P–12–44. 
On May 20, 2019 EPA received a 
SNUN, S–19–5 for the chemical substance from the same submitter as S– 18–4 for use in conductive ink. The 90- day review period for the SNUN expired 
on August 9, 2019. Based on the activities described in the SNUN, including the requirements of the TSCA Order for S–18–4, EPA determined under TSCA section 5(a)(3)(C) that the use is not likely to present an unreasonable risk. EPA modified the TSCA Order for S–18–4 to allow the use described in the SNUN. 
The proposed amendment would (1) 
remove the new uses described in SNUN S–19–5 from the scope of the significant new use and (2) remove the 
new uses described in SNUN S–18–4 from the scope of the significant new use except where that use does not include the protective measures described in the TSCA Order for S–18– 4. 
Potentially Useful Information: 
Certain information may be potentially useful to characterize the health and environmental effects of the chemical substance in support of a request to modify the TSCA section 5(e) Order, or if a manufacturer or processor is considering submitting a SNUN. The results of particle size information, specific organ toxicity, carcinogenicity, and acute and chronic aquatic toxicity testing would help characterize the potential health and environmental effects of the chemical substance. 
CFR citation: 40 CFR 721.10663. 
PMN P–12–0292; PMN P–17–217; and SNUN S–19–4 
Chemical name: Coke (coal), 
secondary pitch; a carbon-containing residue from the coking of air blown pitch coke oil and/or pitch distillate; composed primarily of isotropic carbon, it contains small amounts of sulfur and ash constituents. 
CAS number: 94113–91–4. 
Federal Register publication date and 
reference: November 17, 2016 (81 FR 
81264) (FRL–9953–41). 
Basis for the modified significant new 
use rule: P–12–292 states the generic 
(non-confidential) use of the chemical substance is in the carbon graphite industry. The SNUR issued under TSCA sections 5(e)(1)(A)(i) and 5(e)(1)(A)(ii)(I), was based on the chemical substance may present an unreasonable risk of injury to human health. EPA identified concerns for lung effects and cancer to workers exposed to the substance via inhalation based on SAR analysis of test data on analogous respirable, poorly soluble particulates, in the carbon black. The SNUR required notification for use without the personal protective equipment, including a NIOSH-certified respirator with an APF of at least 50 or compliance with a New Chemicals Exposure Limit (NCEL) of 0.0025 mg/ m
3; use without establishment and use 
of a hazard communication program; 
domestic manufacture; use other than the confidential use specified in the TSCA Order; and exceeding an aggregate confidential production volume limit. 
On January 19, 2017, EPA received 
PMN P–17–217 for the same chemical substance for use as an additive to increase the porosity in the manufacture of diesel particulate filters. The 90-day review period for the PMN expired on July 4, 2017. Based on the activities described in the PMN, an Order was issued under TSCA sections 5(a)(3)(B)(ii)(I) and 5(e)(1)(A)(ii)(I), based on a determination that the chemical substance may present an unreasonable risk of injury to human health. In addition to the restrictions identified for the SNUR, the TSCA Order for P–17–217 did not allow processing or use of the chemical substance involving an application method that generates a dust, vapor, mist, or aerosol; permitted use as an additive for diesel particulate filters manufacture to increase the porosity of the filter material for export only (i.e., no use of the additive formulation within the United States); and required certain testing before exceeding an aggregate production volume limit of 2,500,000 kilograms. 
On June 4, 2019, EPA received a 
SNUN, S–19–4 for use of the chemical substance as a lubricating agent in the production of automotive disc brakes. The 90-day review period for the SNUN expired on September 13, 2019. Based on the activities described in the SNUN, EPA determined under TSCA section 5(a)(3)(C) that the use is not likely to present an unreasonable risk. 
The modified SNUR proposes to 
designate as a ‘‘significant new use’’ processing or use of the chemical substance involving an application method that generates a dust, vapor, mist, or aerosol, exceeding an aggregate production volume of 2,500,000 
kilograms, and to allow the uses described in P–17–217 and S–19–4. It would also be a significant new use to use the substance in an additive formulation to produce diesel particulate filters within the United States. 
Potentially Useful Information: 
Certain information may be potentially useful to characterize the health effects of the chemical substance in support of a request 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 proposed SNUR.

toxicity and carcinogenicity testing 
would help characterize the potential health effects of the chemical substance. 
CFR citation: 40 CFR 721.10928. 
V. Rationale for the Proposed Rule 
In those instances where EPA 
expanded the scope of the significant new use, the Agency identified concerns, as discussed in Unit IV., associated with certain uses that are not current. EPA determined that those uses could result in changes in the type or form of exposure to the chemical substance and/or 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, in addition to considering the factors discussed in Unit IV. 
VI. Applicability of the Proposed 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 solicits comments on whether any of the uses that are not currently a significant new use under the current rule, but which would be 
regulated as a ‘‘significant new use’’ if this proposed rule is finalized are ongoing. These specific new uses are processing or use involving an application method that generates a dust, vapor, mist, or aerosol or exceeding an aggregate production volume of 2,500,000 kilograms for the SNUR for 40 CFR 721.10928, worker protection requirements for the SNUR for 40 CFR 721.10663, and the additional worker protection requirements for inhalation exposure for the SNUR for 40 CFR 721.5185. EPA designates April 1, 2020 as the cutoff date for determining whether the new use is ongoing. EPA has decided that the intent of TSCA section 5(a)(1)(B) is best served by designating a use as a significant new use as of the date of public release of the proposed SNUR rather than as of the effective date of the final rule. If uses begun after public release were considered ongoing rather than new, it would be difficult for EPA to establish SNUR notice requirements, because a person could defeat the SNUR by initiating the proposed significant new use before the rule became effective, and then argue that the use was ongoing as of the effective date of the final rule. 
Thus, any persons who begin 
commercial manufacture or processing activities with the chemical substance that are not currently a significant new use under the current rule but which would be regulated as a ‘‘significant new use’’ if this proposed rule is finalized, must cease any such activity as of the effective date of the rule if and when finalized. To resume their activities, these persons would have to comply with all applicable SNUR notice requirements and wait until the notice review period, including all extensions, expires. 
VII. Development and Submission of 
Information 
TSCA section 5 generally does not 
require developing 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 or reasonably ascertainable (40 CFR 720.50). Unit IV. lists potentially useful information for all SNURs in this rule. Descriptions of this information 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. Furthermore, pursuant to TSCA section 4(h), which pertains to reduction of testing on vertebrate animals, EPA encourages dialog 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 
listed in Unit IV. may not be the only means of providing information to evaluate 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 721.25 and 40 CFR 720.40. E–PMN software is available electronically at https://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. The 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 proposed rule would modify 
SNURs for chemical substances that were the subject of a PMN and a SNUN. The Office of Management and Budget (OMB) has exempted these types of actions from review under Executive Order 12866, entitled Regulatory Planning and Review (58 FR 51735, October 4, 1993). 
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. EPA is amending the table in 40 CFR part 9 to list the OMB approval number for the information collection requirements contained in this rule. 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. This Information Collection Request (ICR) was previously subject to public notice and comment prior to OMB approval, and given the technical nature of the table, EPA finds that further notice and comment to amend it is unnecessary. As a result, EPA finds that there is ‘‘good cause’’ under section 553(b)(3)(B) of the Administrative Procedure Act, 5 U.S.C. 553(b)(3)(B), to amend this table without further notice and comment. 
The information collection 
requirements related to this action have already been approved by OMB pursuant to PRA under OMB control number 2070–0012 (EPA ICR No. 574). This action does not impose any burden requiring additional OMB approval. If an entity were to submit a SNUN to the Agency, the annual burden is estimated to average between 30 and 170 hours per response. This burden estimate includes the time needed to review instructions, search existing data sources, gather and maintain the data needed, and complete, review, and submit the required SNUN. 
Send any comments about the 
accuracy of the burden estimate, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques, to the Director, Regulatory Support Division, Office of Mission 
Support (2822T), Environmental Protection Agency, 1200 Pennsylvania Ave. NW, Washington, DC 20460–0001. Please remember to include the OMB control number in any correspondence, but do not submit any completed forms to this address. 
C. Regulatory Flexibility Act (RFA) 
Pursuant to 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. 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 final rule. 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 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, entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999). F. Executive Order 13175: Consultation 
and Coordination With Indian Tribe 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, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 9, 2000), do not apply to this proposed rule. 
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 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 proposed rule does not entail 
special considerations of environmental justice related issues as delineated by Executive Order 12898 (59 FR 7629, February 16, 1994).

FURTHER INFORMATION CONTACT . 
This action may also affect certain 
entities through pre-existing export notification rules under TSCA. If this proposed SNUR revocation becomes effective, persons who export or intend to export the chemical that is the subject of this action would no longer be subject to the TSCA section 12(b)(15 U.S.C. 2611(b) export notification requirements at 40 CFR part 707 that are currently triggered by the SNUR. 
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? 
In the Federal Register of April 5, 
2019 (84 FR 13531) (FRL–9991–19), 
EPA promulgated a SNUR at 40 CFR 721.11193 for the chemical substance identified generically as alpha 1,3- polysaccharide (P–16–581). The SNUR designated certain activities as significant new uses. EPA has received new data on the biosolubility of the chemical substance. Based on its review of these data, EPA now proposes to revoke the SNUR pursuant to 40 CFR 721.185. In this unit, EPA provides a brief description of the chemical
