EPA Clean Air Scientific Advisory Committee, Notification of Public Advisory Committee Meeting; Teleconference Consultation on Project Work Plan for Revised Air Quality Criteria for Ozone and Related Photochemical Oxidants.


Pursuant to the Federal Advisory Committee Act (FACA), as amended (5 U.S.C. App.), Public Law 92-463, notice is hereby given that the Clean Air Scientific Advisory Committee (CASAC) of the U.S. Environmental Protection Agency's (EPA or Agency) Science Advisory Board (SAB) will meet via teleconference on Thursday, February 6, Start Printed Page 35282003, from 10 a.m. to 1 p.m. eastern time. This teleconference meeting will be hosted out of Conference Room 6013, U.S. EPA, Ariel Rios Federal Building North, 1200 Pennsylvania Avenue, NW., Washington, DC 20004. The meeting is open to the public; however, due to limited space, seating will be on a first-come basis. The public may also attend via telephone, however, lines may be limited. Information on how to participate is provided below.

Purpose of this Meeting: The purpose of this public teleconference meeting is for the CASAC to conduct a consultation with EPA on the Project Work Plan for Revised Air Quality Criteria for Ozone and Related Photochemical Oxidants. (Note: A full CASAC review of the first revised draft AQCD for ozone and related photochemical oxidants is scheduled to take place later this calendar year, and will be announced via a separate Federal Register notice.)

Background: EPA promulgates National Ambient Air Quality Standards (NAAQS) based on scientific information assessed in air quality criteria documents (AQCD) issued under the Clean Air Act (CAA), section 108. The CAA also requires periodic (i.e., every five years) revision of criteria and review of NAAQS. Furthermore, section 109 of the CAA directed the establishment of the CASAC (42 U.S.C. 7409). The CASAC has a statutorily-mandated responsibility under the CAA to review and offer scientific and technical advice to the EPA Administrator on the air-quality criteria and regulatory documents which form the basis for the NAAQS. The previous AQCD for ozone, published in July 1996, provided the scientific basis for EPA's promulgation, in July 1997, of a new eight-hour NAAQS for ground-level ozone.

The Project Work Plan for Revised Air Quality Criteria for Ozone and Related Photochemical Oxidants was prepared by EPA's Office of Research and Development (ORD) National Center for Environmental Assessment (NCEA), located at Research Triangle Park (RTP), NC. The plan presents information on EPA's approach to assessing the latest available scientific information to be incorporated into a revised Ozone AQCD, identifies key issues to be addressed in the Ozone AQCD, and includes brief summaries of legislative requirements and the history of previous ozone criteria revisions and NAAQS reviews. ORD will prepare a draft revised Ozone AQCD and subject it to review at expert peer-review workshops, by the public, and by the CASAC.

The main purpose of the forthcoming revised AQCD for Ozone and Related Photochemical Oxidants is to critically evaluate and assess the latest scientific knowledge useful in indicating the kind and extent of all identifiable effects on public health and welfare which may be expected from the presence of these pollutants in the ambient air. ORD will place emphasis on assessment of health and environmental effects information. Other scientific information will also be evaluated, in part to provide a better understanding of key issues such as those associated with ozone photochemistry; issues on environmental ozone concentrations attributable to anthropogenic and background sources; and issues related to the health and environmental effects associated with changes in solar UV radiation and global warming, as mediated by changes in tropospheric ozone. The final Ozone AQCD document will be used by EPA's Office of Air Quality Planning and Standards (OAQPS) in its review of the Ozone NAAQS.

Providing Oral or Written Comments: It is the policy of the EPA Science Advisory Board to accept written public comments of any length, and to accommodate oral public comments whenever possible. The EPA Science Advisory Board expects that public statements presented at its meetings will not be repetitive of previously-submitted oral or written statements. Specific instructions are as follows:

Oral Comments: In general, each individual or group requesting an oral presentation at a face-to-face meeting will be limited to a total time of 10 minutes (unless otherwise indicated above).
