Abstract
The Environmental Protection Agency (EPA) is announcing the availability of a final document titled, "Supplement to the 2019 Integrated Science Assessment for Particulate Matter (Final)" ([EPA/ 600/R-22/028]). 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 reconsideration of the EPA's 2020 final action reviewing the National Ambient Air Quality Standard (NAAQS) for particulate matter (PM). The Supplement represents a targeted review of peer-reviewed studies published since the literature cutoff date (i.e., ~January 2018) of the 2019 Integrated Science Assessment for Particulate Matter (PM ISA). The Supplement and the 2019 p.m. ISA provide the scientific basis for EPA's decisions, in conjunction with additional technical and policy assessments, for the reconsideration of the EPA's 2020 review of the NAAQS and the appropriateness of possible alternative standards.

Supplement to the 2019 Integrated Science Assessment for
Particulate Matter
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is announcing the
availability of a final document titled, ``Supplement to the 2019
Integrated Science Assessment for Particulate Matter (Final)'' ([EPA/
600/R-22/028]). 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 reconsideration of the
EPA's 2020 final action reviewing the National Ambient Air Quality
Standard (NAAQS) for particulate matter (PM). The Supplement represents
a targeted review of peer-reviewed studies published since the
literature cutoff date (i.e., ~January 2018) of the 2019 Integrated
Science Assessment for Particulate Matter (PM ISA). The Supplement and
the 2019 p.m. ISA provide the scientific basis for EPA's decisions, in
conjunction with additional technical and policy assessments, for the
reconsideration of the EPA's 2020 review of the NAAQS and the
appropriateness of possible alternative standards.
DATES: The document will be available on or about May 13, 2022.

ADDRESSES: The ``Supplement to the 2019 Integrated Science Assessment
for Particulate Matter (Final)'' will be available primarily via the
internet on EPA's Integrated Science Assessment for Particulate Matter
at the public docket at <a href="http://www.regulations.gov">http://www.regulations.gov</a>, Docket ID: [EPA-HQ-

SUPPLEMENTARY INFORMATION:
I. Information About the Document
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''; 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 <a href="https://www.epa.gov/naaqs">https://www.epa.gov/naaqs</a>).
EPA has established NAAQS for six criteria pollutants. In
conducting periodic reviews of the air quality criteria and NAAQS, 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 June 10, 2021, the EPA announced its decision to reconsider the
2020 p.m. NAAQS final action, available at: <a href="https://www.epa.gov/newsreleases/epa-reexamine-health-standards-harmful-soot-previous-administration-left-unchanged">https://www.epa.gov/newsreleases/epa-reexamine-health-standards-harmful-soot-previous-administration-left-unchanged</a>. The EPA also announced that, as a part
of the reconsideration, a supplement to the Integrated Science
Assessment (ISA) for Particulate Matter (PM), which was finalized in
December 2019, would be developed. The ``Supplement to the 2019
Integrated Science Assessment for Particulate Matter (External Review
Draft)'' was released for public comment and review by the CASAC on
September 30, 2021 (<a href="https://cfpub.epa.gov/ncea/isa/recordisplay.cfm?deid=352823">https://cfpub.epa.gov/ncea/isa/recordisplay.cfm?deid=352823</a>).
The CASAC PM panel met at a virtual public meeting on November 17-
19, 2021, to review the draft Supplement to the 2019 p.m. ISA (86 FR
52673, September 22, 2021). A virtual public meeting was then held on
February 25, 2022-March 4, 2022, and during this meeting on February
28, 2022, the chartered CASAC considered the CASAC PM Panel's draft
letter to the Administrator on the draft Supplement to the 2019 p.m.
ISA. This meeting was announced in the Federal Register on January 7,
2022 (87 FR 958). Subsequently, on March 18, 2022, the chartered CASAC
provided a consensus letter of their review to the Administrator of the
EPA (<a href="https://casac.epa.gov/ords/sab/f?p=113:0:9895873668768:APPLICATION_PROCESS=REPORT_DOC:::REPORT_ID:1093">https://casac.epa.gov/ords/sab/f?p=113:0:9895873668768:APPLICATION_PROCESS=REPORT_DOC:::REPORT_ID:1093</a>)
. The EPA has considered comments by the chartered CASAC and by the
public in preparing this final Supplement to the 2019 p.m. ISA.
