On Sep 29, 2008 (73 FR 56581), EPA formally initiated its current review of the air quality criteria for ozone, requesting the submission of recent scientific information on specified topics. A draft of EPA’s ‘‘Integrated Review Plan for the Ozone National Ambient Air Quality Standards Review’’ (EPA/452/P–09/001) was made available in September 2009 for public comment and was discussed by the CASAC via a publicly accessible teleconference consultation on November 13, 2009 (74 FR 54562). In August 2010, EPA held a workshop to discuss, with invited scientific experts, initial draft materials prepared in the development of the ISA (75 FR 42085). The first external review draft ISA for Ozone and Related Photochemical Oxidants will be discussed at a public meeting for review by CASAC, and public comments received will be provided to the CASAC review panel.

I. Information About the Document

    Section 108(a) of the Clean Air Act directs the Administrator to 
identify certain pollutants which, among other things, ``cause or 
contribute to air pollution which may reasonably be anticipated to 
endanger public health or welfare'' and to issue air quality criteria 
for them. These 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 [a] pollutant in the ambient air * * *.'' 
Under section 109 of the Act, EPA is then to establish national ambient 
air quality standards (NAAQS) for each

pollutant for which EPA has issued criteria. Section 109(d) of the Act 
subsequently 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 or welfare. 
EPA is also to revise the NAAQS, if appropriate, based on the revised 
air quality criteria.
    Ozone (O3) is one of six principal (or ``criteria'') 
pollutants for which EPA has established NAAQS. Periodically, EPA 
reviews the scientific basis for these standards by preparing an 
Integrated Science Assessment (ISA) (formerly called an Air Quality 
Criteria Document). The ISA, in conjunction with additional technical 
and policy assessments, provide the scientific basis for EPA decisions 
on the adequacy of the current NAAQS and the appropriateness of 
possible alternative standards. The Clean Air Scientific Advisory 
Committee (CASAC), an independent science advisory committee whose 
existence and whose review and advisory functions are mandated by 
Section 109(d)(2) of the Clean Air Act, is charged (among other things) 
with independent scientific review of EPA's air quality criteria.
    On Sep 29, 2008 (73 FR 56581), EPA formally initiated its current 
review of the air quality criteria for ozone, requesting the submission 
of recent scientific information on specified topics. A draft of EPA's 
``Integrated Review Plan for the Ozone National Ambient Air Quality 
Standards Review'' (EPA/452/P-09/001) was made available in September

scientific experts, initial draft materials prepared in the development 
of the ISA (75 FR 42085).
    The first external review draft ISA for Ozone and Related 
Photochemical Oxidants will be discussed at a public meeting for review 
by CASAC, and public comments received will be provided to the CASAC 
review panel. A future Federal Register notice will inform the public 
of the exact date and time of that CASAC meeting.
