Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 94635 

E. Public Comment and Proposed 

Action 

Section 110(k)(4) of the CAA 

authorizes the EPA to conditionally 

approve a plan revision based on a 

commitment by the State to adopt 

specific enforceable measures by a date 

certain but not later than one year after 

the date of the plan approval. 42 U.S.C. 

7410(k)(4). In this instance, the 

enforceable measures that the State 

must submit are new or revised rules 

that correct the rule deficiencies 

identified above. On October 30, 2024, 

the State transmitted a commitment 

letter, dated October 2, 2024, from the 

BAAQMD committing to correct the 

deficiencies identified in this proposed 

action. The State also submitted a letter, 

dated October 30, 2024, from CARB 

committing to submit the revised rules 

to the EPA within 12 months of the 

publication of the final conditional 

approval by the EPA. As authorized in 

section 110(k)(4) of the CAA, the EPA 

proposes to conditionally approve the 

submitted rules based on the 

commitment by the state to adopt 

specific enforceable measures by a date 

certain but not later than one year after 

the date of the plan approval. 

If this proposed conditional approval 

is finalized as proposed, and the 

BAAQMD or the State fail to comply 

with this commitment, the conditional 

approval would convert to a 

disapproval. 

We will accept comments from the 

public on this proposal until December 

30, 2024. If we take final action to 

approve the submitted rules, our final 

action will incorporate these rules into 

the federally enforceable SIP. 

III. Incorporation by Reference 

In this rule, the EPA is proposing to 

include in a final EPA rule regulatory 

text that includes incorporation by 

reference. In accordance with 

requirements of 1 CFR 51.5, the EPA is 

proposing to incorporate by reference 

BAAQMD, Rule 9–4, Nitrogen Oxides 

from Natural Gas-Fired Furnaces, 

amended on March 15, 2023 and 

BAAQMD, Rule 9–6, Nitrogen Oxides 

from Natural Gas-Fired Boilers and 

Water Heaters, adopted March 15, 2023, 

as discussed in section I. of this 

document. The EPA has made, and will 

continue to make, these materials 

available through https://

www.regulations.gov and at the EPA 

Region IX Office (please contact the 

person identified in the FOR FURTHER

INFORMATION CONTACT section of this 

preamble for more information). 

IV. Statutory and Executive Order 

Reviews 

Under the Clean Air Act, 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, provided that 

they meet the criteria of the Clean Air 

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 14094 (88 FR 

21879, April 11, 2023); 

• 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 subject to Executive Order 

13045 (62 FR 19885, April 23, 1997) 

because it proposes to approve a State 

program; 

• Is not a significant regulatory action 

subject to Executive Order 13211 (66 FR 

28355, May 22, 2001); and 

• Is not subject to requirements of 

section 12(ds) 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 Clean Air Act. 

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 rulemaking 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). 

Executive Order 12898 (Federal 

Actions To Address Environmental 

Justice in Minority Populations and 

Low-Income Populations, 59 FR 7629, 

Feb. 16, 1994) directs Federal agencies 

to identify and address 

‘‘disproportionately high and adverse 

human health or environmental effects’’ 

of their actions on communities with 

environmental justice (EJ) concerns to 

the greatest extent practicable and 

permitted by law. Executive Order 

14096 (Revitalizing Our Nation’s 

Commitment to Environmental Justice 

for All, 88 FR 25251, April 26, 2023) 

builds on and supplements E.O. 12898 

and defines EJ as, among other things, 

‘‘the just treatment and meaningful 

involvement of all people, regardless of 

income, race, color, national origin, or 

Tribal affiliation, or disability in agency 

decision-making and other Federal 

activities that affect human health and 

the environment.’’ 

The air agency evaluated EJ 

considerations as part of its rule 

development process even though the 

CAA and applicable implementing 

regulations neither prohibit nor require 

an evaluation. The EPA is taking action 

under the CAA on bases independent of 

the air agency’s evaluation of EJ. Due to 

the nature of the action being taken 

here, this action is expected to have a 

neutral to positive impact on the air 

quality of the affected area. In addition, 

there is no information in the record 

upon which this decision is based that 

is inconsistent with the stated goal of 

Executive Orders 12898 and 14096 of 

achieving EJ for communities with EJ 

concerns.

94636 Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 

SUMMARY: EPA is proposing significant 

new use rules (SNURs) under the Toxic 

Substances Control Act (TSCA) for 

certain chemical substances that were 

the subject of premanufacture notices 

(PMNs). The chemical substances 

received ‘‘not likely to present an 

unreasonable risk’’ determinations 

pursuant to TSCA. The SNURs require 

persons who intend to manufacture 

(defined by statute to include import) or 

process any of these chemical 

substances for an activity that is 

proposed as a significant new use by 

this rulemaking to notify EPA at least 90 

days before commencing that activity. 

The required notification initiates EPA’s 

evaluation of that use, under the 

conditions of use for that chemical 

substance. In addition, the manufacture 

or processing for the significant new use 

may not commence until EPA has 

conducted a review of the required 

notification, made an appropriate 

determination regarding that 

notification, and taken such actions as 

required by that determination. 

DATES: Comments must be received on 

or before December 30, 2024.

SUPPLEMENTARY INFORMATION: 

I. Executive Summary 

A. 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 factors in TSCA section 

5(a)(2) (see also the discussion in Unit 

II.). 

B. What action is the Agency taking? 

EPA is proposing SNURs for chemical 

substances that were the subject of 

PMNs as discussed in Unit III. These 

SNURs, if finalized as proposed, 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. 

C. Does this action apply to me? 

1. General Applicability 

This action applies to you 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 

(NAICS codes 325 and 324110), e.g., 

chemical manufacturing and petroleum 

refineries. 

2. Applicability to Importers and 

Exporters 

This action may also apply to certain 

entities through pre-existing import 

certification and export notification 

requirements under TSCA (https://

www.epa.gov/tsca-import-exportrequirements). 

Chemical importers are subject to 

TSCA section 13 (15 U.S.C. 2612), the 

requirements promulgated at 19 CFR 

12.118 through 12.127, 19 CFR 127.28, 

and the EPA policy in support of import 

certification at 40 CFR part 707, subpart 

B. Chemical importers must certify that 

the shipment of the chemical substance 

complies with all applicable rules and 

orders under TSCA, including 

regulations issued under TSCA sections 

5, 6, 7 and Title IV. 

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 

December 30, 2024 are subject to 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. 

D. What are the incremental economic 

impacts of this action? 

EPA has evaluated the potential costs 

of establishing SNUN reporting 

requirements for potential 

manufacturers (including importers) 

and processors of the chemical 

substances subject to these proposed 

SNURs. This analysis, which is 

available in the docket, is briefly 

summarized here. 

1. Estimated Costs for SNUN 

Submissions 

If a SNUN is submitted, costs are an 

estimated $45,000 per SNUN 

submission for large business submitters 

and $14,500 for small business 

submitters. These estimates include the 

cost to prepare and submit the SNUN 

(including registration for EPA’s Central 

Data Exchange (CDX)), and the payment 

of a user fee. Businesses that submit a 

SNUN would be subject to either a 

$37,000 user fee required by 40 CFR 

700.45(c)(2)(ii) and (d), or, if they are a 

small business as defined at 13 CFR 

121.201, a reduced user fee of $6,480 

(40 CFR 700.45(c)(1)(ii) and (d)) per 

fiscal year 2022. The costs of 

submission for SNUNs will not be 

incurred by any company unless a 

company decides to pursue a significant 

new use as defined in these SNURs. 

Additionally, these estimates reflect the 

costs and fees as they are known at the 

time of this rulemaking. 

2. Estimated Costs for Export 

Notifications 

EPA has also evaluated the potential 

costs associated with the export 

notification requirements under TSCA 

section 12(b) and the implementing 

regulations at 40 CFR part 707, subpart 

D. For persons exporting a substance 

that is the subject of a SNUR, a one-time 

notice to EPA must be provided for the 

first export or intended export to a 

particular country. The total costs of 

export notification will vary by 

chemical, depending on the number of 

required notifications (i.e., the number 

of countries to which the chemical is 

exported). While EPA is unable to make 

any estimate of the likely number of 

export notifications for the chemical 

substances covered by these SNURs, as 

stated in the accompanying economic 

analysis, the estimated cost of the export 

notification requirement on a per unit 

basis is approximately $106.

2. Tips for Preparing Your Comments 

When preparing and submitting your 

comments, see the commenting tips at 

https://www.epa.gov//epa-dockets. 

II. Background 

This unit provides general 

information about SNURs. For 

additional information about EPA’s new 

chemical program go to https://

www.epa.gov/reviewing-new-chemicalsunder-toxic-substances-control-act-tsca. 

A. Significant New Use Determination 

Factors 

TSCA section 5(a)(2) states that EPA’s 

determination that a use of a chemical 

substance is a significant new use must 

be made after consideration of all 

relevant factors, including: 

• The projected volume of 

manufacturing and processing of a 

chemical substance. 

• The extent to which a use changes 

the type or form of exposure of human 

beings or the environment to a chemical 

substance. 

• The extent to which a use increases 

the magnitude and duration of exposure 

of human beings or the environment to 

a chemical substance. 

• The reasonably anticipated manner 

and methods of manufacturing, 

processing, distribution in commerce, 

and disposal of a chemical substance. 

In determining what would constitute 

a significant new use for the chemical 

substances that are the subject of these 

SNURs, EPA considered relevant 

information about the toxicity of the 

chemical substances, and potential 

human exposures and environmental 

releases that may be associated with the 

substances, in the context of the four 

bulleted TSCA section 5(a)(2) factors 

listed in this unit and discussed in Unit 

III. 

These proposed SNURs include PMN 

substances that received a ‘‘not likely to 

present an unreasonable risk’’ 

determination in TSCA section 

5(a)(3)(c). 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 conditions of use as 

significant new uses. 

B. Rationale and Objectives of the 

SNURs 

1. Rationale 

Under TSCA, no person may 

manufacture a new chemical substance 

or manufacture or process a chemical 

substance for a significant new use until 

EPA makes a determination as described 

in TSCA section 5(a) and takes any 

required action. The issuance of a SNUR 

is not a risk determination itself, only a 

notification requirement for ‘‘significant 

new uses,’’ so that the Agency has the 

opportunity to review the SNUN for the 

significant new use and make a TSCA 

section 5(a)(3) risk determination. 

During review of the PMNs submitted 

for the chemical substances that are the 

subject of these proposed SNURs and as 

further discussed in Unit III., EPA 

identified certain other conditions of 

use, in addition to those conditions of 

use intended by the submitter. EPA has 

determined that the chemical under the 

conditions of use is not likely to present 

an unreasonable risk. However, EPA has 

not assessed risks associated with 

certain conditions of use. EPA is 

proposing to designate these other 

circumstances of use as significant new 

uses. As a result, those significant new 

uses cannot occur without going 

through a separate, subsequent EPA 

review and determination process 

associated with a SNUN. 

2. Objectives 

EPA is proposing these SNURs 

because the Agency wants: 

• To be able to complete its review 

and determination on each of the PMN 

substances, while deferring analysis on 

the significant new uses proposed in 

these rules unless and until the Agency 

receives a SNUN. 

• To have an opportunity to review 

and evaluate data submitted in a SNUN 

before the submitter begins 

manufacturing or processing a listed 

chemical substance for the described 

significant new use. 

• To be obligated to make a 

determination under TSCA section 

5(a)(3) regarding the use described in 

the SNUN, under the conditions of use. 

The Agency will either determine under 

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. 

Issuance of a proposed 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 at 

https://www.epa.gov/tsca-inventory. 

C. Significant New Uses Claimed as CBI 

EPA is proposing to establish certain 

significant new uses which have been 

claimed as CBI subject to Agency 

confidentiality regulations at 40 CFR 

part 2 and 40 CFR part 720, subpart E. 

Absent a final determination or other 

disposition of the confidentiality claim 

under 40 CFR part 2 procedures, EPA is 

required to keep this information 

confidential. EPA promulgated a 

procedure to deal with the situation 

where a specific significant new use is 

CBI, at 40 CFR 721.11. 

Under these procedures a 

manufacturer or processor may request 

EPA to identify the confidential 

significant new use under the rule. The 

manufacturer or processor must show 

that it has a bona fide intent to 

manufacture or process the chemical 

substance and must identify the specific 

use for which it intends to manufacture 

or process the chemical substance. If 

EPA concludes that the person has 

shown a bona fide intent to manufacture 

or process the chemical substance, EPA 

will identify the confidential significant 

new use to that person. Since most of 

the chemical identities of the chemical 

substances subject to these SNURs are 

also CBI, manufacturers and processors 

can combine the bona fide submission 

under the procedure in 40 CFR 721.11 

into a single step. 

D. Applicability of General Provisions 

General provisions for SNURs appear 

in 40 CFR part 721, subpart A. These 

provisions describe persons subject to 

SNURs, recordkeeping requirements, 

exemptions to reporting requirements, 

and applicability of the rule to uses 

occurring before the effective date of the 

rule. Pursuant to 40 CFR 721.1(c), 

persons subject to SNURs must comply 

with the same requirements and EPA 

regulatory procedures as submitters of 

PMNs under TSCA section 5(a)(1)(A). In 

particular, these requirements include 

the information submission 

requirements of TSCA sections 5(b) and 


khammond on DSK9W7S144PROD with PROPOSALS
94638 Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 

5(d)(1), the exemptions authorized by 

TSCA sections 5(h)(1), 5(h)(2), 5(h)(3), 

and 5(h)(5) and the regulations at 40 

CFR part 720. In addition, provisions 

relating to user fees appear at 40 CFR 

part 700. 

Once EPA receives a SNUN, EPA 

must either determine that the 

significant new 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 under 

TSCA section 5 before the manufacture 

(including import) or processing for the 

significant new use can commence. If 

EPA determines that the significant new 

use of the chemical substance 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. 

As discussed in Unit I.C.2., persons 

who export or intend to export a 

chemical substance identified in a 

proposed or final SNUR are subject to 

the export notification provisions of 

TSCA section 12(b), and persons who 

import a chemical substance identified 

in a final SNUR are subject to the TSCA 

section 13 import certification 

requirements. See also https://

www.epa.gov/tsca-import-exportrequirements. 

E. Applicability of the Proposed SNURs 

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 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. The identities of many 

of the chemical substances subject to 

this proposed rule have been claimed as 

confidential per 40 CFR 720.85 and the 

PMN submitter did not intend to engage 

in the other circumstances of use that 

are designated as significant new uses 

for the chemical substances subject to 

this proposed rule. Based on this, the 

Agency believes that it is highly 

unlikely that any of the significant new 

uses identified in Unit III. are ongoing. 

When the chemical substances 

identified 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. Persons who 

begin manufacture or processing of the 

chemical substances for a significant 

new use identified on or after the 

designated cutoff date specified in Unit 

III.A. 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 TSCA 

section 5 allowing manufacture or 

processing to proceed. 

F. Important Information About SNUN 

Submissions 

1. SNUN Submissions 

SNUNs must be submitted on EPA 

Form No. 7710–25, generated using ePMN 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-chemicalsunder-toxic-substances-control-act-tsca. 

2. 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, then TSCA section 

5(b)(1)(A) requires such information to 

be submitted to EPA at the time of 

submission of the SNUN. 

In the absence of a rule, TSCA 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. 

To assist with EPA’s analysis of the 

SNUN, submitters are encouraged, but 

not required, to provide the potentially 

useful information identified for the 

chemical substance in Unit III.C. 

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). For more information on 

alternative test methods and strategies

The potentially useful information 

described in Unit III. may not be the 

only means of providing information to 

evaluate the chemical substance 

associated with the significant new 

uses. However, submitting a SNUN 

without any test data may increase the 

likelihood that EPA will take action 

under TSCA sections 5(e) or 5(f). EPA 

recommends that potential SNUN 

submitters contact EPA early enough so 

that they will be able to conduct the 

appropriate tests. 

SNUN submitters should be aware 

that EPA will be better able to evaluate 

SNUNs which provide detailed 

information on the following: 

• Human exposure and 

environmental release that may result 

from the significant new use of the 

chemical substances. 

III. Chemical Substances Subject to 

These Proposed SNURs 

A. What is the designated cutoff date for 

determining whether the new use is 

ongoing for these chemical substances? 

EPA designates November 29, 2024 as 

the cutoff date for determining whether 

the new use is ongoing. This 

designation is explained in more detail 

in Unit II.E. 

B. What information is provided for 

each chemical substance? 

For each chemical substance 

identified in Unit III.C., EPA provides 

the following information: 

• PMN number (the proposed CFR 

citation assigned in the regulatory text 

section of this document). 

• Chemical name (generic name, if 

the specific name is claimed as CBI). 

• Chemical Abstracts Service Registry 

Number (CASRN) (if assigned for nonconfidential chemical identities). 

• Basis for the SNUR. 

• Potentially useful information. 

The regulatory text section of this 

document specifies the activities 

designated as significant new uses. 

Certain new uses, including production 

volume limits and other uses designated 


khammond on DSK9W7S144PROD with PROPOSALS
Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 94639 

in the proposed rules, may be claimed 

as CBI. 

The chemical substances have 

undergone premanufacture review. In 

addition to those conditions of use 

intended by the submitter, EPA has 

identified certain other circumstances of 

use. EPA has preliminarily determined 

that the chemicals under their 

conditions of use are not likely to 

present an unreasonable risk. However, 

EPA has not assessed risks associated 

with the other circumstances of use for 

these chemicals. EPA is proposing to 

designate these other circumstances of 

use as significant new uses. As a result, 

those significant new uses cannot occur 

without first going through a separate, 

subsequent EPA review and 

determination process associated with a 

SNUN. 

C. Which chemical substances are 

subject to this proposed rule? 

The substances subject to the 

proposed rules in this document are as 

follows: 

PMN Number (Proposed CFR Citation): 

P–20–168 (40 CFR 721.11955) 

Chemical Name: Polyolefin 

polyamine succinimide, carbopolycycle 

alkoxylated (generic). 

CASRN: Not available. 

Basis for Action: The PMN states that 

the use of the PMN substance will be as 

a lubricating additive for engine oils, 

transmission and hydraulic fluid, and 

gear oil applications. Based on 

comparison to analogous chemical 

substances and the structural alert for 

aliphatic amines, EPA has identified 

concerns for irritation to the eyes, skin, 

and respiratory tract if the chemical 

substance is not used following the 

limitation noted. The conditions of use 

of the PMN substance as described in 

the PMN include the following 

protective measure: 

• Use of the PMN substance only as 

a lubricating additive for engine oils, 

transmission and hydraulic fluid, and 

gear oil applications. 

The proposed SNUR would designate 

as a ‘‘significant new use’’ the absence 

of this protective measure. 

Potentially Useful Information: EPA 

has determined that certain information 

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 will be 

designated by this SNUR. EPA has 

determined that the results of skin 

irritation testing may be potentially 

useful to characterize the health effects 

of the PMN substance. 

PMN Number (Proposed CFR Citation): 

P–21–5 (40 CFR 721.11956) 

Chemical Name: Carbonmonocyclic 

alkene polymer with alkyl alkenoate, 

alkyl alkenoate, alkyl alkenoate and 

polyalkyldiene alkenoate (generic). 

CASRN: Not available. 

Basis for Action: The PMN states that 

the use of the PMN substance will be as 

a polymeric additive in gear oils. Based 

on comparison to analogous chemical 

substances, information provided in the 

Safety Data Sheet (SDS), and physical/ 

chemical properties, EPA has identified 

concerns for skin and eye irritation and 

lung effects (lung overload) if the 

chemical substance is not used 

following the limitation noted. The 

conditions of use of the PMN substance 

as described in the PMN include the 

following protective measure: 

• No manufacture, processing, or use 

of the PMN substance in any manner 

that results in worker inhalation 

exposure to the PMN substance. 

The proposed SNUR would designate 

as a ‘‘significant new use’’ the absence 

of this protective measure. 

Potentially Useful Information: EPA 

has determined that certain information 

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 will be 

designated by this SNUR. EPA has 

determined that the results of skin 

irritation, eye irritation, and specific 

target organ toxicity testing may be 

potentially useful to characterize the 

health effects of the PMN substance. 

PMN Number (Proposed CFR Citation): 

P–21–95 (40 CFR 721.11957) 

Chemical Name: 1-tetradecene, 

homopolymer, hydrogenated, byproducts from, C28–42 fraction. 

CASRN: 2263959–83–5. 

Basis for Action: The PMN states that 

the use of the PMN substance will be as 

a base oil for crankcase motor oil, 

transmission oil, and other industrial 

applications such as compressor and 

gear fluids and consumer use as a 

carrier fluid for additives to motor oils 

and automatic transmission fluids. 

Based on comparison to an analogous 

chemical substance and on physical/ 

chemical properties, EPA has identified 

concerns for blood, respiratory tract, 

and lung effects including aspiration 

hazard if the chemical substance is not 

used following the limitation noted. The 

conditions of use of the PMN substance 

as described in the PMN include the 

following protective measure: 

• No processing of the PMN 

substance other than in an enclosed 

system when heated. 

The proposed SNUR would designate 

as a ‘‘significant new use’’ the absence 

of this protective measure. 

Potentially Useful Information: EPA 

has determined that certain information 

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 will be 

designated by this SNUR. EPA has 

determined that the results of specific 

target organ toxicity and pulmonary 

effects testing may be potentially useful 

to characterize the health effects of the 

PMN substance. 

PMN Number (Proposed CFR Citation): 

P–21–174 (40 CFR 721.11958) 

Chemical Name: Carbonic acid, ester, 

polymer with alkanediol (C=4,5) 

(generic). 

CASRN: Not available. 

Basis for Action: The PMN states that 

the generic (non-confidential) use of the 

PMN substance will be as a raw material 

for polyurethane. Based on test data 

submitted on the PMN substance, EPA 

has identified concerns for aquatic 

toxicity if the chemical substance is not 

used following the limitation noted. The 

condition of use of the PMN substance 

as described in the PMN includes the 

following protective measure: 

• No release of the PMN substance 

resulting in surface water 

concentrations that exceed 200 ppb. 

The proposed SNUR would designate 

as a ‘‘significant new use’’ the absence 

of this protective measure. 

Potentially Useful Information: EPA 

has determined that certain information 

may be potentially useful to characterize 

the environmental effects of the PMN 

substance if a manufacturer or processor 

is considering submitting a SNUN for a 

significant new use that will be 

designated by this SNUR. EPA has 

determined that the results of chronic 

aquatic toxicity testing may be 

potentially useful to characterize the 

environmental effects of the PMN 

substance. 

PMN Number (Proposed CFR Citation): 

P–23–17 (40 CFR 721.11959) 

Chemical Name: Hydrolyzed 

collagen, polymer with aromatic 

isocyanate, N-triethoxysylil-alkanamine, 

pectic polysaccharide and poly alkyl 

alcohol (generic). 

CASRN: Not available. 

Basis for Action: The PMN states that 

the use of the PMN substance will be as 

an encapsulant for time-released 

delivery of fragrance. Based on potential 

changes to the molecular weight or 

composition of the PMN substance, EPA 

has identified concerns for lung toxicity 


khammond on DSK9W7S144PROD with PROPOSALS
94640 Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 

if the chemical substance is not used 

following the limitation noted. The 

conditions of use of the PMN substance 

as described in the PMN include the 

following protective measure: 

• Use of the PMN substance only as 

an encapsulant for time-released 

delivery of fragrance. 

The proposed SNUR would designate 

as a ‘‘significant new use’’ the absence 

of this protective measure. 

Potentially Useful Information: EPA 

has determined that certain information 

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 will be 

designated by this SNUR. EPA has 

determined that the results of 

pulmonary effects testing may be 

potentially useful to characterize the 

health effects of the PMN substance. 

IV. Statutory and Executive Order 

Reviews 

Additional information about these 

statutes and Executive orders can be 

found at https://www.epa.gov/lawsregulations-and-executive-orders. 

A. Executive Order 12866: Regulatory 

Planning and Review and Executive 

Order 14094: Modernizing Regulatory 

Review 

This action proposes to establish 

SNURs for new chemical substances 

that were the subject of PMNs. The 

Office of Management and Budget 

(OMB) has exempted these types of 

actions from review under Executive 

Order 12866 (58 FR 51735, October 4, 

1993), as amended by Executive Order 

14094 (88 FR 21879, April 11, 2023). 

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 SNURs have 

already been approved by OMB 

pursuant to PRA under OMB control 

number 2070–0038 (EPA ICR No. 1188). 

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 submission. 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. 

EPA always welcomes your feedback 

on the burden estimates. Send any 

comments about the accuracy of the 

burden estimate, and any suggested 

methods for improving the collection 

instruments or instruction or 

minimizing respondent burden, 

including through the use of automated 

collection techniques. 

C. Regulatory Flexibility Act (RFA) 

I certify that this action will not have 

a significant economic impact on a 

substantial number of small entities 

under the RFA (5 U.S.C. 601 et seq.). 

The requirement to submit a SNUN 

applies to any person (including small 

or large entities) who intends to engage 

in any activity described in the final 

rule as a ‘‘significant new use.’’ Because 

these uses are ‘‘new,’’ based on all 

information currently available to EPA, 

EPA has concluded that no small or 

large entities presently engage in such 

activities. 

A SNUR requires that any person who 

intends to engage in such activity in the 

future must first notify EPA by 

submitting a SNUN. Although some 

small entities may decide to pursue a 

significant new use in the future, EPA 

cannot presently determine how many, 

if any, there may be. However, EPA’s 

experience to date is that, in response to 

the promulgation of SNURs covering 

over 1,000 chemicals, the Agency 

receives only a small number of notices 

per year. For example, the number of 

SNUNs received was 16 in Federal fiscal 

year (FY) FY2018, five in FY2019, seven 

in FY2020, 13 in FY2021, 11 in FY2022, 

and 15 in FY2023, and only a fraction 

of these submissions were from small 

businesses. 

In addition, the Agency currently 

offers relief to qualifying small 

businesses by reducing the SNUN 

submission fee from $37,000 to $6,480. 

This lower fee reduces the total 

reporting and recordkeeping cost of 

submitting a SNUN to about $14,500 per 

SNUN submission for qualifying small 

firms. Therefore, the potential economic 

impacts of complying with these 

proposed SNURs 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 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) 

This action does not contain an 

unfunded mandate of $100 million or 

more (in 1995 dollars) in any one year 

as described in UMRA, 2 U.S.C. 1531– 

1538, and does not significantly or 

uniquely affect small governments. 

Based on EPA’s experience with 

proposing and finalizing SNURs, State, 

local, and Tribal governments have not 

been impacted by SNURs, and EPA does 

not have any reasons to believe that any 

State, local, or Tribal government will 

be impacted by these SNURs. In 

addition, the estimated costs of this 

action to the private sector do not 

exceed $183 million or more in any one 

year (the 1995 dollars are adjusted to 

2023 dollars for inflation using the GDP 

implicit price deflator). The estimated 

costs for this action are discussed in 

Unit I.D. 

E. Executive Order 13132: Federalism 

This action will not have federalism 

implications as specified in Executive 

Order 13132 (64 FR 43255, August 10, 

1999), because it is not expected to have 

a substantial direct effect on States, on 

the relationship between the national 

government and the States, or on the 

distribution of power and 

responsibilities among the various 

levels of government. Accordingly, the 

requirements of Executive Order 13132 

do not apply to this action. 

F. Executive Order 13175: Consultation 

and Coordination With Indian Tribal 

Governments 

This action will not have Tribal 

implications as specified in Executive 

Order 13175 (65 FR 67249, November 9, 

2000), because it is not expected to have 

substantial direct effects on Indian 

Tribes, significantly or uniquely affect 

the communities of Indian Tribal 

governments and does not involve or 

impose any requirements that affect 

Indian Tribes. Accordingly, the 

requirements of Executive Order 13175 

do not apply to this action. 

G. Executive Order 13045: Protection of 

Children From Environmental Health 

Risks and Safety Risks 

This action is not subject to Executive 

Order 13045 (62 FR 19885, April 23, 

1997), because it does not concern an 

environmental health or safety risk. 

Since this action does not concern a 

human health risk, EPA’s 2021 Policy 


khammond on DSK9W7S144PROD with PROPOSALS
Federal Register / Vol. 89, No. 230 / Friday, November 29, 2024 / Proposed Rules 94641 

on Children’s Health also does not 

apply. Although the establishment of 

these SNURs do not address an existing 

children’s environmental health 

concern because the chemical uses 

involved are not ongoing uses, SNURs 

require that persons notify EPA at least 

90 days before commencing 

manufacture (defined by statute to 

include import) or processing of any of 

these chemical substances for an 

activity that is designated as a 

significant new use by this rulemaking. 

This notification allows EPA to assess 

the intended uses to identify potential 

risks and take appropriate actions before 

the activities commence. 

H. Executive Order 13211: Actions 

Concerning Regulations That 

Significantly Affect Energy Supply, 

Distribution, or Use 

This action is not a ‘‘significant 

energy action’’ as defined in Executive 

Order 13211 (66 FR 28355, May 22, 

2001), because it is not likely to have a 

significant adverse effect on the supply, 

distribution, or use of energy. 

I. National Technology Transfer and 

Advancement Act (NTTAA) 

This action does not involve any 

technical standards subject to NTTAA 

section 12(d) (15 U.S.C. 272 note). 

J. Executive Order 12898: Federal 

Actions To Address Environmental 

Justice in Minority Populations and 

Low-Income Populations and Executive 

Order 14096: Revitalizing Our Nation’s 

Commitment to Environmental Justice 

for All 

This action does not concern human 

health or environmental conditions and 

therefore cannot be evaluated with 

respect to the potential for 

disproportionate impacts on non-white 

and low-income populations in 

accordance with Executive Order 12898 

(59 FR 7629, February 16, 1994) and 

Executive Order 14096 (88 FR 25251, 

April 26, 2023). Although this action 

does not concern human health or 

environmental conditions, the 

premanufacture notifications required 

by these SNURs allows EPA to assess 

the intended uses to identify potential 

disproportionate risks and take 

appropriate actions before the activities 

commence.

SUMMARY: EPA is issuing this 

supplemental proposal to update the 

significant new use rules (SNURs) 

previously proposed under the Toxic 

Substances Control Act (TSCA) for 

seventeen chemical substances that 

were the subject of premanufacture 

notices (PMNs) and are also subject to 

an Order issued by EPA pursuant to 

TSCA. The SNURs would require 

persons who intend to manufacture 

(defined by statute to include import) or 

process any of these seventeen chemical 

substances for an activity that is 

proposed as a significant new use by 

this rulemaking to notify EPA at least 90 

days before commencing that activity. 

The required notification initiates EPA’s 

evaluation of the conditions of use for 

that chemical substance. In addition, the 

manufacture or processing for the 

significant new use may not commence 

until EPA has conducted a review of the 

required notification, made an 

appropriate determination regarding 

that notification, and taken such actions 

as required by that determination. 

DATES: Comments must be received on 

or before December 30, 2024.

SUPPLEMENTARY INFORMATION: 

I. Executive Summary 

A. 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 factors in TSCA section 

5(a)(2) (see also the discussion in Unit 

II.). 

B. What action is the Agency taking? 

EPA is proposing SNURs for chemical 

substances discussed in Unit III. These 

SNURs, if finalized as proposed, 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. 

C. Does this action apply to me? 

1. General Applicability 

This action applies to you 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 

(NAICS codes 325 and 324110), e.g., 

chemical manufacturing and petroleum 

refineries.
