Abstract
The Environmental Protection Agency (EPA) is preparing an Integrated Science Assessment (ISA) as part of the review of the primary (health-based) National Ambient Air Quality Standards (NAAQS) for oxides of nitrogen. As part of this review, EPA is announcing a series of public workshops to evaluate preliminary draft materials that will inform the development of the ISA for oxides of nitrogen. Preliminary materials are not being released externally but will be provided to the panelists to guide discussions that will inform the development of the draft ISA for oxides of nitrogen. The workshops are being organized by EPA's Center for Public Health and Environmental Assessment (CPHEA) within the Office of Research and Development and will be held by webinar and teleconference on October 8, October 30, and October 31. Members of the public may attend the webinars as observers. Space in the teleconferences may be limited, and reservations will be accepted on a first-come, first-served basis.

2024 Workshops To Obtain Input on Initial Draft Materials for the
Integrated Science Assessment (ISA) for Oxides of Nitrogen--Health
Criteria
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of workshop.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is preparing an
Integrated Science Assessment (ISA) as part of the review of the
primary (health-based) National Ambient Air Quality Standards (NAAQS)
for oxides of nitrogen. As part of this review, EPA is announcing a
series of public workshops to evaluate preliminary draft materials that
will inform the development of the ISA for oxides of nitrogen.
Preliminary materials are not being released externally but will be
provided to the panelists to guide discussions that will inform the
development of the draft ISA for oxides of nitrogen. The workshops are
being organized by EPA's Center for Public Health and Environmental
Assessment (CPHEA) within the Office of Research and Development and
will be held by webinar and teleconference on October 8, October 30,
and October 31. Members of the public may attend the webinars as
observers. Space in the teleconferences may be limited, and
reservations will be accepted on a first-come, first-served basis.
DATES: The workshops will be held on October 8, October 30, and October
31.
ADDRESSES: The workshops will be held by webinar and teleconference.
The website information and call-in number for the webinars are
available to registered participants. Please register by going to

SUPPLEMENTARY INFORMATION:
I. Information About the Workshop
Section 108(a) of the Clean Air Act directs the Administrator to
identify certain air pollutants which, among other things, ``cause or
contribute to air pollution which may reasonably be anticipated to
endanger public health or welfare''; \1\ 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
NAAQS for each pollutant for which EPA has issued criteria. Section
109(d)(1) 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 or welfare. EPA is also required to review and, if
appropriate, revise the NAAQS, based on the revised air quality
criteria (for more information on the NAAQS review process, see <a href="https://www.epa.gov/naaqs">https://www.epa.gov/naaqs</a>).
---------------------------------------------------------------------------
\1\ Under Clean Air Act section 302(h), welfare effects include,
but are not limited to, ``effects on soils, water, crops,
vegetation, manmade materials, animals, wildlife, weather,
visibility, and climate, damage to and deterioration of property,
and hazards to transportation, as well as effects on economic values
and on personal comfort and well-being.''
---------------------------------------------------------------------------
EPA has established NAAQS for six criteria pollutants including
oxides of nitrogen. Periodically, EPA reviews the scientific basis for
these standards by preparing an ISA. In conjunction with additional
technical and policy assessments conducted by EPA's Office of Air
Quality Planning and Standards (OAQPS), the ISA provides the scientific
and technical basis for EPA decisions on the adequacy of the current
NAAQS and the appropriateness of possible alternative standards.
CPHEA is holding a series of workshops to inform the Agency's
evaluation of the scientific evidence for the oxides of nitrogen. The
purpose of these workshops is to obtain input on the scientific content
of preliminary draft materials that will inform the development of the
draft ISA. Workshop sessions will include discussion of preliminary
draft materials from subject areas which may include exposure
assessment, toxicology, epidemiology, air quality/exposure, and fate
and transport. These preliminary materials are not being released as an
external draft but will be provided to the panelists to guide
discussions and inform the development of the draft ISA for Oxides of
Nitrogen--Health Criteria. These workshops are planned to help ensure
that the ISA, once developed, is up-to-date and focuses on the key
[[Page 73415]]
evidence necessary to inform the underlying scientific basis for the
review of the primary NAAQS for oxides of nitrogen. EPA is planning to
release the external review draft of the ISA for Oxides of Nitrogen--
Health Criteria for review by the Clean Air Scientific Advisory
Committee (CASAC) and the public in late 2025.
II. Workshop Information
Members of the public may attend the webinars as observers. Space
in the teleconferences may be limited, and reservations will be
accepted on a first-come, first-served basis. Registration for the
workshop is available online at <a href="https://www.eventbrite.com/o/us-epa-81991238023">https://www.eventbrite.com/o/us-epa-81991238023</a>.
