Significant New Use Rules on Certain 

Chemical Substances (22–4.5e) 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: EPA is issuing significant new 

use rules (SNURs) under the Toxic 

Substances Control Act (TSCA) for 

certain chemical substances that were 


ddrumheller on DSK120RN23PROD with RULES1
100362 Federal Register / Vol. 89, No. 239 / Thursday, December 12, 2024 / Rules and Regulations 

the subject of premanufacture notices 

(PMNs) and are also subject to an Order 

issued by EPA pursuant to TSCA. The 

SNURs require persons to notify EPA at 

least 90 days before commencing the 

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 in the SNUR. The 

required notification initiates EPA’s 

evaluation of the conditions of that 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: This rule is effective February 

10, 2025. For purposes of judicial 

review, this rule shall be promulgated at 

1 p.m. (EST) on December 26, 2024. 

ADDRESSES: The docket for this action,

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). 

B. What action is the Agency taking? 

EPA is finalizing SNURs under TSCA 

section 5(a)(2) for the chemical 

substances identified in Unit III. These 

chemical substances were the subject of 

PMNs and are also subject to an Order 

issued by EPA pursuant to TSCA 

section 5(e)(1)(A), as required by the 

determinations made under TSCA 

section 5(a)(3)(B). The SNURs identify 

as significant new uses any 

manufacturing, processing, use, 

distribution in commerce, or disposal 

that does not conform to the restrictions 

imposed by the underlying TSCA 

Orders, consistent with TSCA section 

5(f)(4). The SNURs require persons who 

intend to manufacture or process any of 

these chemical substances for an 

activity that is designated as a 

significant new use in the SNURs to 

notify EPA at least 90 days before 

commencing that activity. 

Previously, EPA proposed SNURs for 

these chemical substances in the 

Federal Register of June 11, 2024 (89 FR 

49121 (FRL–11912–01–OCSPP)). The 

docket includes information considered 

by the Agency in developing the 

proposed and final rules, including 

public comments and EPA’s responses 

to the comments received as discussed 

in Unit II.E. 

C. Does this action apply to me? 

1. General Applicability 

This action applies to you if you 

manufacture, process, or use the 

chemical substances identified in Unit 

III. 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 in 19 CFR 12.118 through 

12.127, 19 CFR 127.28, and 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 identified in Unit 

III. 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. 

D. What are the incremental economic 

impacts of this action? 

EPA has evaluated the potential costs 

of establishing SNUN reporting 

requirements for potential 

manufacturers and processors of the 

chemical substances identified in Unit 

III. This analysis, which is available in 

the docket, is briefly summarized here. 

1. Estimated Costs for SNUN 

Submissions 

A SNUR requires that any person who 

intends to engage in such activity in the 

future must first notify EPA by 

submitting a SNUN. 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)). 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 pre-existing 

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 


ddrumheller on DSK120RN23PROD with RULES1
Federal Register / Vol. 89, No. 239 / Thursday, December 12, 2024 / Rules and Regulations 100363 

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. 

II. Background 

A. General Information About SNURS 

Unit II. of the proposed rule provides 

general information about SNURs, and 

additional information about EPA’s new 

chemical program is available at https:// 

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

B. Applicability of the Significant New 

Use Designation 

To establish a significant new use, 

EPA must determine that the use is not 

ongoing. As discussed in Unit II.E. of 

the proposed rule, EPA concluded that 

the proposed significant new uses were 

not ongoing. If EPA subsequently 

determines that such a use was ongoing 

as of the date of publication of the 

proposed rule and did not cease prior to 

issuance of the final rule, EPA will not 

designate that use as a significant new 

use in the final rule. EPA has no 

information to suggest that any of the 

significant new uses identified in this 

rule are ongoing. 

As discussed in the Federal Register 

of April 24, 1990 (55 FR 17376 (FRL– 

3658–5)), 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 

publication of the proposed rule rather 

than as of the effective date of the final 

rule. The objective of EPA’s approach is 

to ensure that a person cannot impede 

finalization of a SNUR by initiating a 

significant new use after publication of 

the proposed rule but before the 

effective date of the final rule. Uses 

arising after the publication of the 

proposed rule are distinguished from 

uses that are identified in the final rule 

as having been ongoing on the date of 

publication of the proposed rule. The 

former would be new uses, the latter 

ongoing uses, except that uses that are 

identified as ongoing as of the 

publication of the proposed rule would 

not be considered ongoing uses if they 

have ceased by the date of issuance of 

a final rule. 

In the unlikely event that before a 

final rule becomes effective a person 

begins commercial manufacturing 

(including importing) or processing of 

the chemical substances for a use that is 

designated as a significant new use in 

that final rule, such a person would 

have to cease any such activity upon the 

effective date of the final rule. To 

resume their activities, these persons 

would have to first comply with all 

applicable SNUR notification 

requirements and wait until all TSCA 

prerequisites for the commencement of 

manufacture or processing have been 

satisfied. 

Issuance of a SNUR for a chemical 

substance does not signify that the 

chemical substance is listed on the 

TSCA Chemical Substance Inventory 

(TSCA Inventory). Guidance on how to 

determine if a chemical substance is on 

the TSCA Inventory is available on the 

internet at https://www.epa.gov/tscainventory. 

C. 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 as identified for the 

chemical substance in Unit III.C. of the 

proposed rule. 

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 

to reduce vertebrate animal testing, visit 

https://www.epa.gov/assessing-andmanaging-chemicals-under-tsca/ 

alternative-test-methods-and-strategiesreduce. 

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 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 about human exposure and 

environmental release that may result 

from the significant new use of the 

chemical substances. 

D. Public Comments on Proposed Rule 

and EPA Responses 

EPA received public comments on the 

proposed SNURs, and prepared a 

Response to Comment document that 

provides the Agency responses. The 

comments and the Response to 

Comment document are available in the 

docket. As described in the Response to 

Comment document, EPA is finalizing 

these SNURs with the following 

changes: 

• For PMN P–21–56 (40 CFR 

721.11868), EPA has reviewed the new 

test data submitted by the PMN 

submitter and no longer has the concern 

for skin sensitization based on the 

weight of available scientific evidence. 

The explanation is provided in the 

revised human health risk assessment, 

which has been added to the docket. 

EPA is modifying the significant new 

use terms included in the final SNUR. 

Two significant new uses, 

manufacturing the substance beyond 24 

months and the requirement that the 

substance be classified as a skin 

sensitization risk on labels and the 

Safety Data Sheets, are not included in 

the final SNUR, and the company’s 


ddrumheller on DSK120RN23PROD with RULES1
100364 Federal Register / Vol. 89, No. 239 / Thursday, December 12, 2024 / Rules and Regulations 

consent order is being modified 

accordingly. 

• EPA inadvertently assigned the 

same CFR number to several proposed 

SNURs and has updated the CFR 

numbering for those SNURs. The 

proposed CFR numbering ranged from 

§§ 721.11860 through 721.11890, and 

the corrected CFR numbering ranges 

from §§ 721.11863 through 721.11893. 

III. Chemical Substances Subject to 

These SNURs 

A. What is the designated cutoff date for 

ongoing uses? 

EPA designates the date of 

publication of the proposed rule as the 

cutoff date for determining whether the 

new use is ongoing, i.e., June 11, 2024 

(89 FR 49121 (FRL–11912–01–OCSPP)). 

This designation is explained further in 

Unit II.B. 

B. What information is provided for 

each chemical substance? 

In Unit III.C. of the proposed rule, 

EPA provided the following information 

for each chemical substance subject to 

these SNURs: 

• PMN number (the 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) or Accession Number 

(if assigned for non-confidential 

chemical identities). 

• Basis for the SNUR (e.g., Effective 

date of and basis for the TSCA Order). 

• 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, may be claimed as CBI. 

In addition, as discussed in Unit III.B. 

of the proposed rule, these SNURs 

include PMN substances that are subject 

to orders issued under TSCA section 

5(e)(1)(A), as required by the 

determinations made under TSCA 

section 5(a)(3)(B). Those TSCA Orders 

require protective measures to limit 

exposures or otherwise mitigate the 

potential unreasonable risk. As such, 

the SNURs identify as significant new 

uses any manufacturing, processing, 

use, distribution in commerce, or 

disposal that does not conform to the 

restrictions imposed by the underlying 

TSCA Orders, consistent with TSCA 

section 5(f)(4). 

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 establishes 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 estimate. 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 7 in Federal fiscal 

year (FY) 2020, 13 in FY2021, 11 in 

FY2022, and 15 in FY2023, 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 $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 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

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 

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 the 

identified chemical substances for an 

activity that is designated as a 

significant new use by the SNUR. 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 

EPA believes that this type of action 

does not concern human health or 

environmental conditions and therefore 

cannot be evaluated with respect to 

potentially disproportionate and 

adverse effects on communities with 

environmental justice concerns in 

accordance with Executive Orders 

12898 (59 FR 7629, February 16, 1994) 

and 14096 (88 FR 25251, April 26, 

2023). Although this action does not 

concern human health or environmental 

conditions, the 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. 

K. Congressional Review Act (CRA) 

This action is subject to the CRA (5 

U.S.C. 801 et seq.), and EPA will submit 

a rule report to each House of the 

Congress and to the Comptroller General 

of the United States. This action is not 

a ‘‘major rule’’ as defined by 5 U.S.C. 

804(2).

Finding of Failure To Submit State 

Implementation Plan Submissions for 

the 2008 and 2015 Ozone National 

Ambient Air Quality Standards; 

California; San Diego County Area 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final action. 

SUMMARY: The Environmental Protection 

Agency (EPA) is taking final action to 

find that California has failed to submit 

State Implementation Plan (SIP) 

elements required under the Clean Air 

Act (CAA or the ‘‘Act’’) for the 2008 and 

2015 8-hour ozone national ambient air 

quality standards (NAAQS) in the San 

Diego County nonattainment area. 

California was required to submit a SIP 

submission demonstrating that 

reasonably available control technology 

(RACT) requirements are implemented 

at the ‘‘Serious’’ nonattainment area 

classification for the 2008 and 2015 

ozone NAAQS. The State submitted the 

required RACT demonstrations on 

December 28, 2020, but subsequently 

withdrew portions of its submission on 

August 23, 2024. If the EPA has not 

affirmatively found that the State has 

submitted a complete SIP for the 

withdrawn RACT element requirements 

within 18 months of this finding, the 

offset sanction will apply in the area. If 

within six additional months the EPA 

has still not affirmatively determined 

that the State has submitted a complete 

SIP for the withdrawn RACT element 

requirements, the highway funding 

sanction will apply in the area. No later 

than two years after the EPA makes this 

finding, if the State has not submitted 

and the EPA has not approved each of 

the required RACT elements, the EPA 

must promulgate a federal 

implementation plan (FIP) to address 

the remaining requirements. 

DATES: This action is effective January 

13, 2025. 

ADDRESSES: The EPA has established a 

docket for this action under Docket ID 

No. EPA–R09–OAR–2024–0369. All

SUPPLEMENTARY INFORMATION: Section 

553 of the Administrative Procedure Act 

(APA), U.S.C. 553(b)(B), provides that 

an agency may issue a rule without 

providing notice and an opportunity for 

public comment when that agency finds 

for good cause that notice and public 

procedure are impracticable, 

unnecessary, or contrary to public 

interest. The EPA has determined that 

there is a good cause for issuing this 

finding without prior proposal and 

opportunity for comment because there 

is little or no judgment involved for the 

EPA to make a finding of failure to 

submit SIPs or elements of SIPs required 

by the CAA, where states have not 

submitted a required SIP revision, made 

incomplete submissions, or, as in this 

case, withdrawn an existing submission. 

In such circumstances, the EPA finds 

that notice and public procedures are 

unnecessary and that this constitutes 

good cause under 5 U.S.C 553(b)(B). 

Throughout this document, ‘‘we,’’ 

‘‘us,’’ and ‘‘our’’ refer to the EPA.

Submit 

III. Final Action 

IV. Statutory and Executive Order Reviews 

I. Background 

Emissions of volatile organic 

compounds (VOCs) and oxides of 

nitrogen (NOX) contribute to the 

production of ground-level ozone, smog, 

and particulate matter (PM), which 

harm human health and the 

environment. Section 110(a) of the CAA 

requires states to submit regulations that 

control VOC and NOX emissions. 

Sections 182(b)(2) and (f) require that 

SIPs for ozone nonattainment areas that 

are classified as Moderate or above 

implement RACT for any source 

covered by a Control Techniques 

Guidelines (CTG) document and for any 

major source of VOCs or NOX. Section 

III.D of the preamble to the EPA’s final 

rule to implement the 2008 ozone 

NAAQS further discusses RACT 

requirements.1 Section III.D states, in 

part, that RACT SIPs must contain 

adopted RACT regulations, 

certifications that existing provisions 

meet the RACT requirement (where 

appropriate), and/or negative 

declarations that no sources in the 

nonattainment area are covered by a 

specific CTG.2 It also provides that 

states must submit appropriate 

supporting information for their RACT 

submissions as described in the EPA’s 

implementation rule for the 1997 ozone 

NAAQS.3

The San Diego County ozone 

nonattainment area is classified as
