Final Integrated Science Assessment
for Oxides of Nitrogen, Oxides of
Sulfur, and Particulate Matter—
Ecological Criteria
AGENCY

Agency (EPA).
ACTION
: Notice of availability.
SUMMARY
: The Environmental Protection
Agency (EPA) is announcing the
availability of a final document titled,
‘‘Final Integrated Science Assessment
for Oxides of Nitrogen, Oxides of Sulfur,
and Particulate Matter—Ecological
Criteria’’ (EPA/600/R–20/278). The
document was prepared by the Center
for Public Health and Environmental
Assessment (CPHEA) within EPA’s
Office of Research and Development
(ORD) as part of the review of the
secondary (welfare-based) national
ambient air quality standards (NAAQS)
for oxides of nitrogen, oxides of sulfur,
and particulate matter. This ISA
represents an update of the 2008
Integrated Science Assessment for
Oxides of Nitrogen and Sulfur—
Ecological Criteria (EPA/600/R–08/
082F) and the 2009 Integrated Science
Assessment for Particulate Matter (EPA/
600/AR–08/139F). The ISA, in
conjunction with additional technical
and policy assessments, provides the
basis for EPA’s decisions on the
adequacy of the current NAAQS and the
appropriateness of possible alternative
standards.
DATES
: The document will be available
on or about October 16, 2020.
ADDRESSES
: The ‘‘Final Integrated
Science Assessment for Oxides of
Nitrogen, Oxides of Sulfur, and
Particulate Matter—Ecological Criteria’’
will be available primarily via the
internet on EPA’s Integrated Science
Assessment for Oxides of Nitrogen,
Oxides of Sulfur, and Particulate Matter
page at https://www.epa.gov/isa/

particulate-matter or the public docket
at http://www.regulations.gov, Docket
ID: [EPA–HQ–ORD–2013–0620 and
EPA–HQ–OAR–2014–0128]. A limited
number of CD–ROM copies will be
available. Contact Ms. Marieka Boyd by

SUPPLEMENTARY INFORMATION
:
I. Information About the Document
Section 108(a) of the Clean Air Act
directs the Administrator to identify
certain air pollutants, emissions of
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. The 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 https://
www.epa.gov/naaqs).
EPA has established NAAQS for six
criteria pollutants. Presently the EPA is
reviewing the secondary air quality
criteria and NAAQS for oxides of
nitrogen, oxides of sulfur, and
particulate matter. Periodically, EPA
reviews the scientific basis for these
standards by preparing an Integrated
Science Assessment (ISA) (formerly
called an Air Quality Criteria
Document). The ISA provides the
scientific basis for EPA’s decisions, in
conjunction with additional technical
and policy assessments, on the
adequacy of the current NAAQS and the
appropriateness of possible alternative
standards. The Clean Air Scientific
Advisory Committee (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 the
EPA’s air quality criteria.
On August 21, 2013 (78 FR 53452),
EPA formally initiated its current
review of the air quality criteria for the
ecological effects of oxides of nitrogen
and oxides of sulfur, and the associated
secondary (welfare-based) NAAQS,
requesting the submission of recent
scientific information on specified
topics. Similarly, on December 3, 2014
(79 FR 71764), EPA formally initiated its
current review of the air quality criteria
for the particulate matter NAAQS. EPA
conducted two workshops—the first on
March 4–6, 2014, for oxides of nitrogen
and oxides of sulfur (79 FR 8644,
February 13, 2014), and the second on
February 11, 2015 (79 FR 71764,
December 3, 2014), for particulate
matter—to gather input from invited
scientific experts, both internal and
external to EPA, as well as from the
public, regarding key science and policy
issues relevant to the review of the these
secondary NAAQS. Teleconference
workshops with invited scientific
experts, both internal and external to
EPA, were held on August 25–27, 2015
(80 FR 48316, August 12, 2015), and
June 13, 2016 (81 FR 89262, May 11,
2016), to discuss initial draft materials
prepared in the development of the draft
ISA.
These science and policy issues were
incorporated into EPA’s ‘‘Draft
Integrated Review Plan for the
Secondary National Ambient Air
Quality Standard for Oxides of Nitrogen
and Oxides of Sulfur’’ as well as the
‘‘Integrated Review Plan for the National
Ambient Air Quality Standards for
Particulate Matter.’’ The Draft Integrated
Review Plan (IRP) for oxides of nitrogen
and oxides of sulfur was available for
public comment (80 FR 69220, Monday,
November 9, 2015) and discussion by
the CASAC via publicly accessible

IRP for particulate matter was available
for public comment (81 FR 2297, April
19, 2016) and discussion by the CASAC
via publicly accessible teleconference
consultation (81 FR 13362, March 14,
2016) prior to release of the final
document (81 FR 87933, December 6,
2016). The ‘‘First External Review Draft
Integrated Science Assessment for
Oxides of Nitrogen, Oxides of Sulfur,
and Particulate Matter—Ecological
Criteria’’ was available for public
comment (82 FR 15703, March 30, 2017)
and discussed by CASAC and the public
at meetings on May 24–25, 2017 (82 FR
15701, March 30, 2017).
The ‘‘Second External Review Draft
Integrated Science Assessment for
Oxides of Nitrogen, Oxides of Sulfur,
and Particulate Matter—Ecological
Criteria’’ was available for public
comment (83 FR 29786, June 26, 2018)
and discussed by CASAC and the public
at meetings on September 5–6, 2018 (83
FR 31755, July 9, 2018), and April 27,
2020 (85 FR 16093, March 20, 2020).
Subsequently, CASAC provided a letter
of their review on May 5, 2020, to the
EPA Administrator, which can be
