Call for Information on the Integrated 

Science Assessment for Ozone and 

Related Photochemical Oxidants 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice; call for information. 

SUMMARY: The Environmental Protection 

Agency (EPA) is preparing an Integrated 

Science Assessment (ISA) as part of the 

review of the air quality criteria and the 

primary (health-based) and secondary 

(welfare-based) National Ambient Air 

Quality Standards (NAAQS) for Ozone 

(O3) and related photochemical 

oxidants. The ISA will be developed by 

the Center for Public Health and 

Environmental Assessment (CPHEA) 

within EPA’s Office of Research and 

Development. When final, the ISA is 

intended to update the previous ISA for 

O3 and related photochemical oxidants 

(EPA/600/R–20/012), published in 2020. 

Interested parties are invited to assist 

EPA in developing and refining the 

scientific information base for the 

review of the O3 NAAQS by submitting 

research studies and data that have been 

published or accepted for publication 

since January 1, 2018. 

DATES: All communications and 

information should be received by EPA 

by October 24, 2023. 

ADDRESSES: Information may be 

submitted electronically, by mail, by 

facsimile, or by hand delivery/courier. 

Please follow the detailed instructions 

as provided in the section of this notice 

entitled SUPPLEMENTARY INFORMATION. 

FOR FURTHER INFORMATION CONTACT: For 

information on the public comment 

period, contact the ORD Docket at the 

EPA Headquarters Docket Center; 

phone: 202–566–1752; facsimile: 202– 

566–9744; or email: ord.docket@

epa.gov. For technical information, 

contact Qingyu Meng; phone: 919–541–

or Jeffrey Herrick; phone: 919–541– 

7745; or email: herrick.jeffrey@epa.gov. 

SUPPLEMENTARY INFORMATION: 

I. Information About the Document 

Section 108(a) of the Clean Air Act 

(the Act) directs the Administrator to 

identify and list certain air pollutants 

which, among other things, ‘‘cause or 

contribute to air pollution which may 

reasonably be anticipated to endanger 

public health or welfare;’’ 1 and then to 

issue air quality criteria for them. 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 [the] 

pollutant in the ambient air . . . .’’. 

Under section 109 of the Act, EPA is 

then to establish NAAQS for each 

pollutant for which EPA has issued 

criteria. Section 109(d)(1) of the Act 

additionally requires periodic review 

and, if appropriate, revision of existing 

air quality criteria to reflect advances in 

scientific knowledge on the effects of 

the pollutant on public health and 

welfare. Under the same provision, EPA 

is also to periodically review and, if 

appropriate, revise the NAAQS, based 

on the revised air quality criteria. 

Documents and technical materials 

associated with NAAQS reviews are 

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

Photochemical oxidants, including 

O3, are one of six ‘‘criteria’’ pollutants 

for which EPA has established NAAQS, 

and O3 is the current indicator for that 

NAAQS. In its periodic review of the air 

quality criteria for these pollutants, EPA 

reviews the currently available science 

and prepares an ISA. The ISA provides 

the scientific foundation for EPA’s 

NAAQS reviews, in conjunction with 

additional technical and policy 

assessments, and for the Administrator’s 

decisions on the adequacy of the current 

NAAQS and the appropriateness of 

possible alternative standards. Early 

steps in this review process include 

announcing the initiation of the review 

of the air quality criteria and the 

NAAQS and the intention of the EPA to 

develop an ISA, and requesting that the 

public submit scientific literature that 

they want to bring to the attention of the 

Agency as it begins this process. The 

Clean Air Scientific Advisory 

Committee (CASAC), whose review and 

advisory functions are mandated by 

section 109(d)(2) of the Clean Air Act, 

is charged, among other things, with the 

independent scientific review of the air 

quality criteria. In conjunction with the 

CASAC review, the public will have an 

opportunity to review and comment on 

the draft ISA. The ISA developed in this 

review of the air quality criteria and O3

NAAQS will build on the scientific 

assessment from the last review,2

focusing on assessing and integrating 

the information newly available since 

that considered in the 2020 ISA. With 

regard to development of the ISA, the 

public is encouraged to assist in 

identifying relevant scientific 

information for the review by 

submitting research studies that were

not part of the prior review, and that 

have been published or accepted for 

publication in a peer-reviewed journal. 

The Agency is interested in obtaining 

newly available information, 

particularly concerning toxicological 

studies of effects of controlled exposure 

to O3 in laboratory animals, humans, 

and in vitro systems; epidemiologic 

(observational) studies of health effects 

associated with ambient O3 exposures in 

human populations; studies examining 

populations and life stages that may be 

at increased risk of O3-related health 

effects.. For studies examining effects on 

welfare or the environment, studies that 

address or provide new information on 

terrestrial biota are of particular interest, 

including effects of O3 on vegetation; 

communities and populations of plants 

and associated biota, as well as 

exposure-response relationships 

between O3 in ambient air and specific 

welfare effects. The EPA also seeks 

recent information in other areas of O3

research such as atmospheric chemistry 

and physics, sources and emissions, 

analytical methodology, transport and 

transformation in the environment, and 

ambient concentrations. 

The Agency also seeks information 

regarding the design and scope of the 

review of the air quality criteria to 

ensure that it addresses key policyrelevant issues and considers the new 

science that is relevant to informing our 

understanding of these issues. The 

Agency seeks new scientific information 

that may address key uncertainties 

identified in the last O3 NAAQS review, 

which are provided in section 3.6 of the 

2020 Policy Assessment (EPA–452/R– 

20–001, May 2020).3 The Agency also 

seeks new scientific information or data 

that may address scientific and 

technical issues raised in two more 

recent letters from CASAC: one dated 

November 22, 2022 (EPA–CASAC–23– 

001) 4 and the other dated June 9, 2023 

(EPA–CASAC–23–002).5 Other 

opportunities for submission of new 

peer-reviewed, published (or in-press) 

papers will be possible as part of public 

comment on the draft ISA that will be 

reviewed by the CASAC.
