The Staff Paper is intended to ‘‘bridge the gap’’ between the scientific review contained in the Criteria Document and the public health and welfare policy judgments required of the Administrator in reviewing the NAAQS. In January 2005, a first external review draft of the Criteria Document was released by EPA for public review and comment and for review by the CASAC of EPA’s Science Advisory Board (70 FR 4850, January 31, 2005) at a public meeting held in May 2005. Comments received from review of the first draft document were considered in preparing the second draft Criteria Document released for public review and comment in August 2005 (70 FR 51810, August 31, 2005). Based on this document, the first Draft Staff Paper was released in November 2005 (70 FR 69761, November 17, 2005), and reviewed at a public meeting on December 8, 2005. Based on the information contained in the final Criteria Document, released in March 2006 (71 FR 10030, February 28, 2006), the second Draft Staff Paper includes assessments and analyses related to: (1) Air quality characterization; (2) integration and evaluation of health information; (3) exposure analysis; (4) health risk assessment; and (5) evaluation of information on vegetation damage and other welfare effects. The second Draft Staff Paper contains staff conclusions and options with respect to possible retention or revision of the current primary (health-based) and secondary (welfare-based) standards and identifies alternative standards for consideration by the Administrator. The draft Exposure Analysis, Risk Assessment and Environmental Assessment technical support documents describe and present the results from an ozone exposure analysis and health risk assessment in several urban areas, and the impact of ozone on the environment. Draft plans upon which these assessments are based, the Ozone Health Assessment Plan: Scope and Methods for Exposure Analysis and Risk Assessment and the Scope and Methods for Environmental Assessment Plan, were previously reviewed by CASAC and the public. Comments VerDate Aug<31>2005 20:08 Jul 17, 2006 Jkt 208001 received on those plans have been considered in developing the draft Exposure Analysis, Risk Assessment and Environmental Assessment technical support documents being released at this time. The exposure analysis, risk assessment, and environmental assessment methodologies and results are also discussed in the second Draft Staff Paper. The EPA is soliciting advice and recommendations from the CASAC by means of a peer review of the second Draft Staff Paper and drafts of the Exposure Analysis, Risk Assessment, and Environmental Assessment at an upcoming public meeting of the CASAC scheduled for August 24 and 25, 2006. A Federal Register notice will inform the public of the location of that meeting. Following the CASAC meeting, EPA will consider comments received from CASAC and the public in preparing a final Staff Paper and final Exposure Analysis, Risk Assessment, and Environmental Assessment technical support documents.

II. Background on the Ozone NAAQS Review

    Section 108(a) of the CAA directs the 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 CAA, EPA is then to establish NAAQS for each 
pollutant for which EPA has issued criteria. Section 109(d) of the CAA 
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. 
Also, EPA is to retain or, if appropriate revise, the NAAQS based on 
the revised criteria, which have undergone review by the Clean Air 
Scientific Advisory Committee (CASAC).
    The CASAC, which is comprised of seven members appointed by the EPA 
Administrator, was established under section 109(d)(2) of the CAA (42 
U.S.C. 7409) as an independent scientific advisory committee, in part 
to provide advice, information, and recommendations on the scientific 
and technical aspects of issues related to air quality criteria and 
NAAQS under sections 108 and 109 of the CAA. The CASAC is a Federal 
advisory committee under the Federal Advisory Committee Act (FACA), as 
amended, 5 U.S.C., App. The CASAC Ozone Review Panel consists of the 
members of the chartered CASAC, is supplemented by subject-matter 
experts, and complies with the provisions of FACA.
    Ozone is one of six ``criteria'' pollutants for which EPA has 
established air quality criteria and NAAQS. Presently, EPA is reviewing

[[Page 40720]]

the criteria and NAAQS for ozone. This review includes preparation of 
two key documents, the Air Quality Criteria for Ozone and Related 
Photochemical Oxidants (``Criteria Document'') and a related ``Staff 
Paper.'' The purpose of the Staff Paper is to evaluate the policy 
implications of the key scientific and technical information contained 
in the Criteria Document and identify critical elements that EPA staff 
believe should be considered in reviewing the NAAQS. The Staff Paper is 
intended to ``bridge the gap'' between the scientific review contained 
in the Criteria Document and the public health and welfare policy 
judgments required of the Administrator in reviewing the NAAQS.
    In January 2005, a first external review draft of the Criteria 
Document was released by EPA for public review and comment and for 
review by the CASAC of EPA's Science Advisory Board (70 FR 4850, 
January 31, 2005) at a public meeting held in May 2005. Comments 
received from review of the first draft document were considered in 
preparing the second draft Criteria Document released for public review 
and comment in August 2005 (70 FR 51810, August 31, 2005). Based on 
this document, the first Draft Staff Paper was released in November 
2005 (70 FR 69761, November 17, 2005), and reviewed at a public meeting 
on December 8, 2005. Based on the information contained in the final 
Criteria Document, released in March 2006 (71 FR 10030, February 28, 
2006), the second Draft Staff Paper includes assessments and analyses 
related to: (1) Air quality characterization; (2) integration and 
evaluation of health information; (3) exposure analysis; (4) health 
risk assessment; and (5) evaluation of information on vegetation damage 
and other welfare effects. The second Draft Staff Paper contains staff 
conclusions and options with respect to possible retention or revision 
of the current primary (health-based) and secondary (welfare-based) 
standards and identifies alternative standards for consideration by the 
Administrator.
    The draft Exposure Analysis, Risk Assessment and Environmental 
Assessment technical support documents describe and present the results 
from an ozone exposure analysis and health risk assessment in several 
urban areas, and the impact of ozone on the environment. Draft plans 
upon which these assessments are based, the Ozone Health Assessment 
Plan: Scope and Methods for Exposure Analysis and Risk Assessment and 
the Scope and Methods for Environmental Assessment Plan, were 
previously reviewed by CASAC and the public. Comments received on those 
plans have been considered in developing the draft Exposure Analysis, 
Risk Assessment and Environmental Assessment technical support 
documents being released at this time. The exposure analysis, risk 
assessment, and environmental assessment methodologies and results are 
also discussed in the second Draft Staff Paper.
    The EPA is soliciting advice and recommendations from the CASAC by 
means of a peer review of the second Draft Staff Paper and drafts of 
the Exposure Analysis, Risk Assessment, and Environmental Assessment at 
an upcoming public meeting of the CASAC scheduled for August 24 and 25, 
2006. A Federal Register notice will inform the public of the location 
of that meeting. Following the CASAC meeting, EPA will consider 
comments received from CASAC and the public in preparing a final Staff 
Paper and final Exposure Analysis, Risk Assessment, and Environmental 
Assessment technical support documents.

    Dated: July 13, 2006.
