I. General Information

A. Background

    Section 108 (a) of the Clean Air Act directs the EPA Administrator 
to identify certain pollutants which ``may reasonably be anticipated to 
endanger public health and 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 and welfare. EPA is also to revise the 
NAAQS, if appropriate, based on the revised criteria.
    Ozone is one of six ``criteria'' pollutants for which EPA has 
established air quality criteria and NAAQS. On September 26, 2000 (65 
FR 57810), EPA formally initiated its current review of the criteria 
and NAAQS for ozone, requesting the submission of recent scientific 
information on specified topics. A draft Project Work Plan for a 
revised Ozone AQCD, with preliminary outlines for the proposed 
chapters, was released for public comment (66 FR 67524, December 31, 
2001) and reviewed by the Clean Air Scientific Advisory Committee 
(CASAC) of EPA's Science Advisory Board (68 FR 3527, January 24, 2003). 
EPA later convened a series of workshops to discuss draft sections and 
chapters that had been developed

for revising the existing Ozone AQCD (68 FR 17365, April 9, 2003, and 
68 FR 60369, October 22, 2003).
    In January 2005, EPA announced the availability of the First 
External Review Draft of the revised Ozone AQCD for public review and 
comments (70 FR 4850, January 31, 2005) and presented the draft to the 
CASAC Ozone Review Panel on May 4-5, 2005. Taking into account public 
and CASAC comments, EPA prepared and announced a Second External Review 
Draft for public review and comment (70 FR 51810, August 31, 2005).
    At a public meeting in December 2005, EPA presented the Second 
External Review Draft to the Clean Air Scientific Advisory Committee 
(CASAC) for their review. Public comments and comments from the CASAC 
Review Panel were considered in preparing the final Ozone AQCD 
announced in this Federal Register notice.
