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
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.
• Make sure to submit your
comments by the comment period
deadline identified.
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 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
E:\FR\FM\12MRN1.SGM

srobinson on DSKHWCL6B1PROD with NOTICES
11878
Federal Register / Vol. 75, No. 48 / Friday, March 12, 2010 / Notices
quantities.’’ Under section 109 of the
CAA, EPA establishes national ambient
air quality standards (NAAQS) for each
listed pollutant, with the NAAQS based
on the air quality criteria. 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 revise the
NAAQS, if appropriate, based on the
revised criteria.
The EPA is currently conducting a
joint review of the existing secondary
(welfare-based) NAAQS for oxides of
nitrogen (NOX) and oxides of sulfur
(SOX). Because NOX, SOX, and their
associated transformation products are
linked from an atmospheric chemistry
perspective as well as from an
environmental effects perspective, and
because of the National Research
Council’s 2004 recommendations to
consider multiple pollutants in forming
the scientific basis for the NAAQS, EPA
has decided to jointly assess the science,
risks, and policies relevant to protecting
the public welfare associated with NOX
and SOX. This is the first time since
NAAQS were established in 1971 that a
joint review of these two pollutants has
been conducted. Since both the CASAC
and EPA have recognized these
interactions historically, and the science
related to these interactions has
continued to evolve and grow to the
present day, there is a strong basis for
considering them together.
As part of this review of the current
secondary (welfare-based) NAAQS for
NOX and SOX, EPA’s OAQPS staff are
preparing a first draft Policy
Assessment. The objective of this
assessment is to evaluate the policy
implications of the key scientific
information contained in the document
Integrated Science Assessment for
Oxides of Nitrogen and SulfurEcological Criteria (https://
cfpub.epa.gov/ncea/cfm/
recordisplay.cfm?deid=201485),
prepared by EPA’s National Center for
Environmental Assessment (NCEA) and
the results from the analyses contained
in the Risk and Exposure Assessment
for Review of the Secondary National
Ambient Air Quality Standards for
Oxides of Nitrogen and Oxides of Sulfur
(https://www.epa.gov/ttn/naaqs/
standards/no2so2sec/cr_rea.html). The
first draft Policy Assessment will be
available online at: https://www.epa.gov/
ttn/naaqs/standards/no2so2sec/
index.html. This first draft Policy
Assessment will be reviewed by the
CASAC during a public meeting to be

California State Motor Vehicle
Pollution Control Standards;
Amendments to the California Zero
Emission Vehicle (ZEV) Regulation;
Waiver Request; Opportunity for
Public Hearing
AGENCY: Environmental Protection
Agency (EPA).
ACTION: Notice of opportunity for public
hearing and comment.
SUMMARY: The California Air Resources
Board (CARB) has notified EPA that it
has adopted amendments to its
regulations related to zero emission
vehicles (ZEVs) in California. By letter
dated September 17, 2009, CARB
requested that EPA confirm that its
amendments as they affect model years
2008–2011 are within-the-scope of
previous waivers of preemption issued
by EPA. CARB also requests that EPA
confirm that amendments as they affect
the 2012 and subsequent model years
are also within-the-scope of previous
waivers of preemption issued by EPA;
or, in the alternative, that EPA grant a
new waiver of preemption for these
future model years. This notice
announces that EPA has tentatively
scheduled a public hearing concerning
California’s request and that EPA is
accepting written comment on the
request.
DATES: EPA has tentatively scheduled a
public hearing concerning CARB’s
request on April 13, 2010 at 10 a.m. EPA
will hold a hearing only if any party
notifies EPA by April 1, 2010,
expressing its interest in presenting oral
testimony. By April 6, 2010, any person
who plans to attend the hearing may
call David Dickinson at (202) 343–9256
to learn if a hearing will be held or may
check the following Web site for an
update: https://www.epa.gov/otaq/
cafr.htm.
Parties wishing to present oral
testimony at the public hearing should
also provide written notice to David
Dickinson at the address noted below. If

Fmt 4703
Sfmt 4703
EPA receives a request for a public
hearing, that hearing will be held at
1310 L St, NW., Washington, DC 20005.
If EPA does not receive a request for
a public hearing, then EPA will not hold
a hearing, and instead consider CARB’s
request based on written submissions to
the docket. Any party may submit
written comments by May 17, 2010.
ADDRESSES: EPA will make available for
public inspection materials submitted
by CARB, written comments received
from interested parties, and any
testimony given at the public hearing.
Materials relevant to this proceeding are
contained in the Air and Radiation
Docket and Information Center,
maintained in Docket No. EPA–HQ–
OAR–2009–0780. The docket is located
at The Air Docket, Room 3334, 1301
Constitution Avenue, NW., Washington,
DC 20460, and may be viewed between
8 a.m. and 5:30 p.m., Monday through
Friday. The telephone is (202) 566–
1742. A reasonable fee may be charged
by EPA for copying docket material.
Additionally, an electronic version of
the public docket is available through
the Federal government’s electronic
public docket and comment system.
You may access EPA dockets at https://
www.regulations.gov. After opening the

SUPPLEMENTARY INFORMATION:
(A) Procedural History
Within CARB’s 1990–1991 California
Low Emission Vehicle (LEV I)
rulemaking, CARB required that ten
percent of the passenger cars and
LDT1s 1 marketed by all but small
volume manufacturers were required to
be ZEVs starting in the 2003 model year.
EPA granted California an initial waiver
of preemption for California’s original
1990 ZEV requirements in January 1993
as part of the LEV I waiver.2 CARB
amended its original ZEV requirements
in 1996, and in January 2001, EPA
