II. Information About the Document

    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).
    Presently the EPA is reviewing the air quality criteria and NAAQS 
for photochemical oxidants and O3.\1\ The EPA's overall plan 
for this review is presented in the Integrated Review Plan for the 
Ozone NAAQS (IRP).\2\ As described in the IRP, the EPA is preparing an 
Integrated Science Assessment for (ISA), a draft of which was released 
in September 2019 for public comment and review by the CASAC (84 FR 
50836).\3\ The PA, when final, serves to ``bridge the gap'' between the 
scientific and technical information in the final ISA and any air 
quality, exposure and risk analyses available in the review, and the 
judgments required of the Administrator in determining whether to 
retain or revise the existing ozone NAAQS. The draft PA builds upon 
information presented in the draft ISA and the draft exposure and risk 
analyses (presented in an appendix to the draft PA). The draft PA 
document will be available on or about October 31, 2019, on the EPA's 
website at https://www.epa.gov/naaqs/ozone-o3-air-quality-standards. 
The EPA is soliciting advice and recommendations from the CASAC by 
means of a review of this draft document at an upcoming public meeting 
of the CASAC. Information about this public meeting, including the 
dates and location, will be published as a separate notice in the 
Federal Register. Following the CASAC meeting, the EPA will consider 
comments received from the CASAC and the public in preparing revisions 
to these documents.
