ENVIRONMENTAL PROTECTION AGENCY
[EPA-HQ-OAR-2007-0492; FRL-9132-8]
Draft Document Related to the Review of the National Ambient Air
Quality Standards for Particulate Matter
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of Extension of Comment Period.
-----------------------------------------------------------------------
SUMMARY: The EPA is announcing an extension of the public comment
period for a draft assessment document titled, Policy Assessment for
the Review of the Particulate Matter National Ambient Air Quality
Standards--First External Review Draft (75 FR 4067; January 26, 2010).
The EPA is extending the comment period that originally was scheduled
to end on April 12, 2010. The extended comment period will close on
April 26, 2010. The EPA recognizes that this document was released for
public comment nine days later than originally anticipated. As a
result, the Agency is extending the comment period by two weeks to
provide stakeholders and the public with adequate time to conduct
appropriate analysis and prepare meaningful comments.
DATES: Comments on the above report must be received on or before April
26, 2010.

may not be able to consider your comment. Electronic files should avoid
the use of special characters, any form of encryption, and be free of
any defects or viruses.
Docket: All documents in the docket are listed in the http://www.regulations.gov index. Although listed in the index, some

General Information
A. What Should I Consider as I Prepare My Comments for EPA?
1. Submitting CBI. Do not submit this information to EPA through
http://www.regulations.gov or e-mail. Clearly mark the part or all of
the information that you claim to be CBI. For CBI information in a disk
or CD ROM that you mail to EPA, mark the outside of the disk or CD ROM
as CBI and then identify electronically within the disk or CD ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
2. Tips for Preparing Your Comments. When submitting comments,
remember to:
Identify the rulemaking by docket number and other
identifying information (subject heading, Federal Register date and
page number).
Follow directions--The agency may ask you to respond to
specific questions or organize comments by referencing a Code of
Federal Regulations (CFR) part or section number.
Explain why you agree or disagree; suggest alternatives
and substitute language for your requested changes.
Describe any assumptions and provide any technical
information and/or data that you used.
If you estimate potential costs or burdens, explain how
you arrived at your estimate in sufficient detail to allow for it to be
reproduced.
Provide specific examples to illustrate your concerns, and
suggest alternatives.
Explain your views as clearly as possible, avoiding the
use of profanity or personal threats.
Make sure to submit your comments by the comment period
deadline identified.
SUPPLEMENTARY INFORMATION: Under section 108(a) of the Clean Air Act
(CAA), the Administrator identifies and lists certain pollutants which
``cause or contribute to air pollution which may reasonably be
anticipated to endanger public health or welfare.'' The EPA then issues
air quality criteria for these listed pollutants, which are commonly
referred to as ``criteria pollutants.'' 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, in varying quantities.'' Under section
109 of the CAA, EPA establishes primary (health-based) and secondary
(welfare-based) national ambient air quality standards (NAAQS) for
pollutants for which air quality criteria are issued. Section 109(d) of
the CAA requires periodic review and, if appropriate, revision of
existing air quality criteria. The revised air quality criteria reflect
advances in scientific knowledge on the effects of the pollutant on
public health or welfare. The EPA is also required to periodically
review and, if appropriate, revise the NAAQS based on the revised air
quality criteria.
As part of the ongoing review of the NAAQS for particulate matter
(PM), EPA released a draft document titled Policy Assessment for the
Review of the Particulate Matter National Ambient Air Quality
Standards--First External Review Draft (March 2010, EPA 452/P-10-003)
for review by the Clean Air Scientific Advisory Committee (CASAC) and
public comment (75 FR 4067; January 26, 2010). The first draft Policy
[[Page 16461]]
Assessment builds upon information presented in the Integrated Science
Assessment for Particulate Matter (Final Report) \1\ and two draft
assessment documents, Quantitative Health Risk Assessment for
Particulate Matter--Second External Review Draft \2\ and Particulate
Matter Urban-Focused Visibility Assessment--Second External Review
Draft.\3\ The first draft Policy Assessment may be accessed online
through EPA's TTN Web site at http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_2007_pa.html. The EPA is soliciting advice and
recommendations from the CASAC by means of a review of the first draft
Policy Assessment at an upcoming public teleconference of the CASAC
that will be held on April 8-9, 2010 (75 FR 8062; February 23, 2010).
The EPA will consider comments received from the CASAC and the public
in preparing revisions to this document. A second draft Policy
Assessment document will be issued later this spring for CASAC and
public review. The EPA will consider CASAC and public comments on the
second draft Policy Assessment in preparing a final Policy Assessment.
The final Policy Assessment will serve to ``bridge the gap'' between
the scientific information and the judgments required of the
Administrator in determining whether it is appropriate to retain or
revise the current PM NAAQS.
