Draft Plan for Development of the Integrated Science Assessment
for Nitrogen Oxides--Health Criteria
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of public comment period.
SUMMARY: The U.S. EPA is announcing the availability of the ``Draft
Plan for Development of the Integrated Science Assessment for Nitrogen
Oxides--Health Criteria.'' The draft document was prepared by the
National Center for Environmental Assessment (NCEA) within EPA's Office
of Research and Development as part of the review of the primary
(health-based) national ambient air quality standards (NAAQS) for
nitrogen dioxide (NO2). The purpose of this draft document
is to communicate the plan for the development of the Integrated
Science Assessment (ISA) for the health effects of nitrogen oxides
(NOX), which will provide a comprehensive assessment of the
current scientific literature pertaining to known and anticipated
effects on public health associated with the NOX in the
EPA is releasing this draft document to seek consultation by the
Clean Air Scientific Advisory Committee (CASAC) and the public (meeting
date and time to be specified in a separate Federal Register notice).
The draft document does not represent and should not be construed to
represent any final EPA policy, viewpoint, or determination. EPA will
consider any public comments submitted in response to this notice when
revising the draft plan for development of the NOX ISA.
DATES: The public comment period begins, May 3, 2013, and ends May 31,
2013. Comments must be received on or before May 31, 2013.
ADDRESSES: The ``Draft Plan for Development of the Integrated Science
Assessment for Nitrogen Oxides--Health Criteria'' will be available
primarily via the Internet on the NCEA home page under the Recent
Additions and Publications menus at http://www.epa.gov/ncea or in the
public docket at http://www.regulations.gov (Docket ID: EPA-HQ-ORD-
2013-0232). A limited number of CD-ROM or paper copies will be
available. Contact Ms. Marieka Boyd by phone (919-541-0031), fax (919-
541-5078), or email ([email protected]) to request either of these,
and please provide your name, your mailing address, and the document
title, ``Draft Plan for Development of the Integrated Science
Assessment for Nitrogen Oxides--Health Criteria'' to facilitate
processing of your request.

I. Information About the Document
Section 108(a) of the Clean Air Act directs the Administrator to
identify certain pollutants, which among other things, ``cause or
contribute to air pollution, which may reasonably be anticipated to
endanger public health or 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 [the] 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) 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 to revise the NAAQS, if appropriate, based on the revised
air quality criteria.
NO2 is one of six criteria pollutants for which EPA has
established NAAQS. Periodically, EPA reviews the scientific basis for
these standards by preparing an ISA (formerly called an Air Quality
Criteria Document). The ISA, in conjunction with additional technical
and policy assessments, provide the scientific basis for EPA decisions
on the adequacy of the current NAAQS and the appropriateness of
possible alternative standards. The CASAC, an independent science
advisory committee whose review and advisory functions are mandated by
Section 109(d)(2) of the Clean Air Act, is charged (among other things)
with independent scientific review of EPA's air quality criteria.
On February 10, 2012 (77 FR 7149), EPA formally initiated its
current review of the air quality criteria for the health effects of
NOX and the primary (health-based) NO2 NAAQS,
requesting the submission of recent scientific information on specified
topics. EPA held a workshop February 29 to March 1, 2013, to discuss
with invited scientific experts, key science and policy issues relevant
to the review of the health effects of NOX (77 FR 7149).
NCEA has prepared a draft plan for development of the ISA for the
health effects of NOX, which communicates the scope,
organization, methodology, and key policy-relevant issues for the ISA.
EPA is planning to release the first external review draft of the
health effects ISA for NOX for review by CASAC and the
public later on in 2013.
Development of the ISA is one phase of the NAAQS review, and a
draft Integrated Review Plan (IRP) is being developed that will
characterize all of the phases of the review of the primary NAAQS for
NO2, including the schedule for the entire review, the
process for conducting the various phases of the review, and the key
policy-relevant science issues that will guide the review. The draft
IRP will be released for review by CASAC and the public later on in
2013 and after consideration of CASAC and public comments, a final IRP
will be issued in early 2014. The IRP will incorporate a revised plan
for ISA development after consideration of CASAC and public comments.
