Air Quality Criteria for Ozone and Related Photochemical Oxidants
AGENCY: Environmental Protection Agency.
ACTION: Notice; call for information.
-----------------------------------------------------------------------
SUMMARY: The National Center for Environmental Assessment, Office of
Research and Development, of the U.S. Environmental Protection Agency
(EPA) is undertaking to update and revise, where appropriate, the Air
Quality Criteria for Ozone and Related Photochemical Oxidants (EPA-600/
P-93-004aF-cF) published in July 1996.
Since completion of the 1996 ozone criteria document, the EPA has
continued to collect scientific information on the effects of ground-
level ozone on health and vegetation. A summary and evaluation of this
and other selected literature that may be particularly relevant to a
review of the National Ambient Air Quality Standards for ozone will be
presented in the forthcoming revised criteria document.
As part of this continuing review, interested parties are invited
to assist the EPA in developing and refining the scientific information
base for updating the air quality criteria for ozone. While EPA has
continued to follow the literature and gather appropriate studies since
early 1996, the Agency is interested in additional new information,
particularly concerning the effects expected from the presence of
ground-level ozone in the ambient air on: humans and laboratory
animals; vegetation, both in agroecosystems (crops) and in natural
ecosystems; nonbiological materials; and global climate. EPA also seeks
recent information in other areas of ozone research such as its
chemistry and physics, sources and emissions, analytical methodology,
transport and transformation in the environment, and ambient
concentrations. To be considered for inclusion in the revised criteria
document, submitted information should be published, accepted for
publication, or have been presented at a public scientific meeting.
DATES: All communications and information must be submitted by December
1, 2000, and addressed to the Project Manager for Ozone and Related
Photochemical Oxidants, National Center for Environmental Assessment
(MD-52), U.S. Environmental Protection Agency, Research Triangle Park,
NC 27711.
Dated: September 15, 2000.

Director, National Center for Environmental Assessment.
