Confidential Business Information (CBI) or other information whose
disclosure is restricted by statute. Do not submit information that you
consider to be CBI or otherwise protected through www.regulations.gov
(or email). The www.regulations.gov Web site is an ``anonymous access''

1. Submitting CBI. Do not submit this information to the EPA
through www.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 the 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,
Identify the rulemaking by docket number and other
identifying information (subject heading, Federal Register date and
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

II. Information Specific to This Document
Two sections of the Clean Air Act (CAA) govern the establishment
and revision of the 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 her ``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 . . .'' 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(b). 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 EPA is also
required to periodically review and, if appropriate, revise the NAAQS
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 existing criteria and standards as
may be appropriate. . . .'' Since the early 1980's, this independent
review function has been performed by the Clean Air Scientific Advisory
Presently, the EPA is reviewing the primary NAAQS for
SO2.\1\ The draft document, announced today, has been
developed as part of the planning phase for the review. This phase
began with a science policy workshop to identify issues and questions
to frame the review.\2\ Drawing from the workshop discussions, the
draft IRP has been prepared jointly by EPA's National Center for
Environmental Assessment, within the Office of Research and
Development, and EPA's Office of Air Quality Planning and Standards,
within the Office of Air and Radiation. The draft IRP presents the
current plan and specifies the schedule for the entire review, the
process for conducting the review, and the key policy-relevant science
issues that will guide the review. This document will be available on
the EPA's Technology Transfer Network (TTN) Web site at http://www.epa.gov/ttn/naaqs/standards/so2/s_so2_index.htmlhttp://www.epa.gov/ttn/naaqs/standards/pb/s_pb_index.html, accessible in the
``Documents from Current Review'' section under ``Planning Documents.''
\1\ The EPA's call for information for this review was issued on
May 10, 2013 (78 FR 27387).
\2\ The EPA held a workshop titled, ``Kickoff Workshop to Inform
EPA's Review of the Primary SO2 NAAQS'' on June 12-13,
2013 (78 FR 27387).
The draft IRP is being made available for CASAC review and for
public comment. Comments should be submitted to the docket, as
described above, by April 17, 2014. Information about the CASAC review
meeting on this planning document, including the dates and location,
will be published as a separate notice in the Federal Register. The
final IRP will be prepared after considering comments from CASAC and
the public. This draft document does not represent and should not be
construed to represent any final EPA policy, viewpoint or
