Extension of Comment Period on Draft Documents Related to the
Review of the Primary National Ambient Air Quality Standard for Sulfur
Oxides

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of extension of public comment period.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing a
30-day extension of the comment period on two draft documents titled,
Risk and Exposure Assessment for the Review of the Primary National
Ambient Air Quality Standard for Sulfur Oxides, External Review Draft
(draft REA) and Policy Assessment for the Review of the Primary
National Ambient Air Quality Standard for Sulfur Oxides, External
Review Draft (draft PA). The EPA is extending the comment period for an
additional 30 days to provide stakeholders and the public with
additional time to review these documents and to prepare meaningful
comments. The original comment period was to end on October 18, 2017.
The extended comment period will now close on November 17, 2017.

DATES: The comment period for the document published in the Federal
Register on September 19, 2017 (82 FR 43756) is extended. Comments must
be received on or before November 17, 2017.

ADDRESSES: Submit your comments, identified by Docket ID No. EPA-HQ-
OAR-2013-0566, to the Federal eRulemaking Portal: http://www.regulations.gov. Follow the online instructions for submitting
comments. Once submitted, comments cannot be edited or withdrawn. The
EPA may publish any comment received to its public docket. Do not
submit electronically any information you consider to be Confidential
Business Information (CBI) or other information whose disclosure is
restricted by statute. Multimedia submissions (audio, video, etc.) must
be accompanied by a written comment. The written comment is considered
the official comment and should include discussion of all points you
wish to make. The EPA will generally not consider comments or comment
contents located outside of the primary submission (i.e., on the Web,
Cloud, or other file sharing system). For additional submission
methods, the full EPA public comment policy, information about CBI or
multimedia submissions, and general guidance on making effective
comments, please visit http://www2.epa.gov/dockets/commenting-epa-dockets. The draft REA and draft PA are available via the Internet at
https://www.epa.gov/naaqs/sulfur-dioxide-so2-primary-air-quality-standards.

SUPPLEMENTARY INFORMATION:

I. General Information

A. What should I consider as I prepare my comments for the EPA?

    1. Submitting CBI. Do not submit this information to EPA through
http://regulations.gov or email. 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 Code of Federal Regulations (CFR) part 2.
    2. Tips for Preparing your Comments. When submitting comments,
remember to:
     Identify the notice 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 CFR part or
section number.
     Explain why you agree or disagree; suggest alternative and
substitute language for your requested changes.
     Describe any assumption 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.

II. Information Specific to the Documents

    Two sections of the Clean Air Act (CAA) govern the establishment
and revision of the national ambient air quality standards (NAAQS).
Section 108 (42 U.S.C. 7408) directs the Administrator to identify and
list certain air pollutants and then to issue air quality criteria for
those pollutants. The Administrator is to list those air pollutants
that in his ``judgment, cause or contribute to air pollution which may
reasonably be anticipated to endanger public health or welfare''; ``the
presence of which in the ambient air results from numerous or diverse
mobile or stationary sources''; and ``for which . . . [the
Administrator] plans to issue air quality criteria . . .'' (42 U.S.C.
7408(a)(1)(A)-(C)). Air quality criteria are intended 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 . . .'' (42 U.S.C. 7408(a)(2)). Under section 109 (42 U.S.C. 7409),
the EPA establishes primary (health-based) and secondary (welfare-
based) NAAQS for pollutants for which air quality criteria are issued.
Section 109(d) 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 revise the NAAQS, if appropriate, based on the
revised criteria. Section 109(d)(2) requires that an independent
scientific review committee ``shall complete a review of the criteria .
. . and the national primary and secondary ambient air quality
standards . . . and shall recommend to the Administrator any new . . .
standards and revisions of the existing criteria and standards as may
be appropriate . . . .'' Since the early 1980s, this independent review
function has been performed by the Clean Air Scientific Advisory
Committee (CASAC).
    Presently, the EPA is reviewing the air quality criteria and
primary NAAQS for sulfur oxides.\1\ The EPA's overall plan for this
review is presented in the Integrated Review Plan for the Primary NAAQS
for Sulfur Dioxide (IRP). The EPA is currently working to finalize the
Integrated Science Assessment for Sulfur Oxides--Health Criteria (ISA),
the second draft of which was reviewed by the CASAC at a public meeting
in March 2017 (82 FR 11449). The Risk and Exposure Assessment Planning
Document for the Review of the Primary National Ambient Air Quality
Standards for Sulfur Oxides (REA Planning Document) was also reviewed
by the CASAC at this meeting (82 FR 11449). The draft REA and draft PA,
which build on information presented in these documents, were the
subject of review by the CASAC at a public meeting on September 18-19,
2017 (82 FR 37213). The EPA will consider comments received from the
CASAC and the public in preparing revisions to these documents. The
draft REA and PA documents, and other documents in this review,
referenced above, are available on the EPA's Technology Transfer
Network Web site at https://www.epa.gov/naaqs/sulfur-dioxide-so2-primary-air-quality-standards.
---------------------------------------------------------------------------

    \1\ The indicator for the current standard is sulfur dioxide.
---------------------------------------------------------------------------

    The notice of availability for the draft REA and draft PA was
originally published on September 19, 2017, with the public comment
period closing on October 18, 2017 (82 FR 43756). We received a request
from a member of the public to extend the comment period by 30 days.
After considering this request, we are extending the comment period
and, as described above, it will now close on November 17, 2017.

    Dated: October 11, 2017.

Director, Office of Air Quality Planning and Standards.
