ENVIRONMENTAL PROTECTION AGENCY
Workshop To Review Initial Draft Materials for the Nitrogen
Oxides (NOX) Integrated Science Assessment (ISA) for Health
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of Workshop.
SUMMARY: As part of the review of the air quality criteria for nitrogen
oxides (NOX) and primary (health-based) National Ambient Air
Quality Standards (NAAQS) for nitrogen dioxide (NO2), EPA is
announcing a workshop to evaluate preliminary draft materials that will
inform the development of the NOX Integrated Science
Assessment (ISA) for health effects. The workshop is being organized by
EPA's National Center for Environmental Assessment (NCEA) within the
Office of Research and Development and will be held on June 11, 2013,
in Research Triangle Park, North Carolina and will be open to
attendance by interested public observers on a first-come, first-served
basis up to the limits of available space.
DATES: The workshop will be held on June 11, 2013, beginning at 9:30
a.m. and ending at 5:00 p.m.
ADDRESSES: The workshop will be held in the auditorium of EPA's main
campus, 109 T.W. Alexander Drive, Research Triangle Park, North

I. Summary of Information About the Workshop
Section 109(d) of the Clean Air Act (CAA) requires the U.S. EPA to
conduct periodic reviews of the air quality criteria for each air
pollutant listed under section 108 of the Act. Based on such reviews,
EPA is to retain or revise the NAAQS for a given pollutant as
appropriate. As part of these reviews, NCEA assesses newly available
scientific information and develops ISA documents (formerly known as
Air Quality Criteria Documents) that provide the scientific basis for
the reviews of the NAAQS.
NCEA-Research Triangle Park is holding this workshop to inform the
Agency's evaluation of the scientific evidence for the review of the
primary NAAQS for NO2. Section 109(b)(1) of the CAA defines
primary NAAQS as standards, ``the attainment and maintenance of which
in the judgment of the Administrator, based on such criteria and
allowing an adequate margin of safety, are requisite to protect the
public health.'' EPA intends to develop a separate ISA, and NAAQS
review, for the secondary (welfare-based) NAAQS for NO2, in
conjunction with a review of the secondary NAAQS for sulfur dioxide.
The purpose of the workshop is to obtain review of the scientific
content of preliminary draft materials that will inform the development
of the draft health effects ISA. Workshop sessions will include review
and discussion of preliminary draft materials on the atmospheric
chemistry of and human exposure to NOX as well as health
effects evidence from in vivo and in vitro animal toxicology, human
clinical, and epidemiology studies. In addition, roundtable discussions
will help identify key studies or concepts within each discipline to
assist EPA in integrating relevant literature within and across
disciplines. These preliminary materials are not being released as an
external draft but will be used to guide workshop discussions and
inform the development of the draft health effects ISA. This workshop
is planned to help ensure that the ISA, once developed, is up-to-date
and focuses on the key evidence to inform the scientific understanding
for the review of the primary NAAQS for NOX. EPA is planning
to release the first external review draft health effects ISA for
NOX for review by the Clean Air Scientific Advisory
Committee and the public in August 2013.
II. Workshop Information
Members of the public may attend the workshop as observers. Space
is limited, and reservations will be accepted on a first-come, first-
