Release of Policy Assessment for the 

Review of the Secondary National 

Ambient Air Quality Standards for 

Oxides of Nitrogen, Oxides of Sulfur 

and Particulate Matter 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability. 

SUMMARY: On or about January 12, 2024, 

the Environmental Protection Agency 

(EPA) will make available the 

document, Policy Assessment for the 

Review of the Secondary National 

Ambient Air Quality Standards for 

Oxides of Nitrogen, Oxides of Sulfur 

and Particulate Matter (PA, EPA–452/ 

R–24–003). This document was 

prepared as part of the current review of 

the secondary national ambient air 

quality standards (NAAQS) for Oxides 

of Nitrogen (NOX), Oxides of Sulfur 

(SOX), and Particulate Matter (PM). The 

PA serves to ‘‘bridge the gap’’ between 

the currently available scientific and 

technical information and the 

judgments required of the Administrator 

in determining whether to retain or 

revise the existing secondary NO2, SO2

and PM NAAQS. The secondary 

NAAQS for oxides of nitrogen, oxides of 

sulfur, and particulate matter are set to 

protect the public welfare from known 

or anticipated effects of these pollutants 

in the ambient air. 

DATES: This document will be available 

on or about January 12, 2024. 

ADDRESSES: This document will be 

available on the EPA’s website at 

https://www.epa.gov/naaqs/nitrogendioxide-no2-and-sulfur-dioxide-so2- 

secondary-air-quality-standards. The 

document will be accessible under 

‘‘Policy Assessments’’ from the current 

review.

Ginger Tennant, Office of Air Quality 

Planning and Standards, (Mail Code 

C504–06), U.S. Environmental 

Protection Agency, P.O. Box 12055, 

Research Triangle Park, NC 27711; 

telephone number: 919–541–4072, or 

email: tennant.ginger@epa.gov. 

SUPPLEMENTARY INFORMATION: Two 

sections of the Clean Air Act (CAA or 

the Act) govern the establishment and 

revision of the NAAQS. Section 108 

directs the Administrator to identify and 

list certain air pollutants and then issue 

‘‘air quality criteria’’ for those 

pollutants. The air quality criteria are to 

‘‘accurately reflect the latest scientific 

knowledge useful in indicating the kind 

and extent of all identifiable effects on 

public health or welfare which may be 

expected from the presence of such 

pollutant in the ambient air . . .’’ (CAA 

section 108(a)(2)). Under section 109 of 

the Act, the EPA is then to establish 

primary (health-based) and secondary 

(welfare-based) NAAQS for each 

pollutant for which the EPA has issued 

air quality criteria. Section 109(d)(1) of 

the Act requires periodic review and, if 

appropriate, revision of existing air 

quality criteria. Revised air quality 

criteria are to reflect advances in 

scientific knowledge on the effects of 

the pollutant on public health and 

welfare. Under the same provision, the 

EPA is also to periodically review and, 

if appropriate, revise the NAAQS, based 

on the revised air quality criteria. 

The Act additionally requires 

appointment of an independent 

scientific review committee that is to 

periodically review the existing air 

quality criteria and NAAQS and to 

recommend any new standards and 

revisions of existing criteria and 

standards as may be appropriate (CAA 

section 109(d)(2)(A)–(B)). Since the 

early 1980s, the requirement for an 

independent scientific review 

committee has been fulfilled by the 

Clean Air Scientific Advisory 

Committee (CASAC). 

The EPA’s overall plan for this review 

is presented in the Integrated Review 

Plan for the Secondary National 

Ambient Air Quality Standards for 

Ecological Effects of Oxides of Nitrogen, 

Oxides of Sulfur and Particulate Matter 

(IRP).1 As described in the IRP, the EPA 

has prepared the Integrated Science 

Assessment (ISA) for Oxides of 

Nitrogen, Oxides of Sulfur and 

Particulate Matter Ecological Criteria 

(U.S. EPA, 2020), drafts of which were 

released in March 2017 and June 2018 

for public comment and review by the 

CASAC.2 A draft of the PA was also 

reviewed by the CASAC (88 FR 17572, 

March 23, 2023; 88 FR 45414, July 17, 

2023). The final PA reflects 

consideration of the advice and 

comments from the CASAC on the draft 

PA, as well as public comments. The PA 

serves to ‘‘bridge the gap’’ between the 

scientific and technical information in 

the 2020 ISA and any air quality, 

exposure, and risk analyses available in 

this review, and the judgments required 

of the Administrator in determining 

whether to retain or revise the existing 

secondary ambient air quality standards 

for NO2, SO2 and PM. The final PA 

document will be available on EPA’s 

website at https://www.epa.gov/naaqs/ 

nitrogen-dioxideno2-and-sulfur-dioxideso2-secondaryair-quality-standards. The 

document briefly described here does 

not represent and should not be 

construed to represent any final EPA 

policy, viewpoint, or determination.
