Adequacy Status of the Indiana and Ohio Portions of the
Cincinnati-Hamilton, Ohio/Kentucky/Indiana, Submitted 8-Hour Ozone
Attainment Demonstration for Transportation Conformity Purposes

AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of adequacy.

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

SUMMARY: In this notice, EPA is notifying the public that we have found
that the motor vehicle emissions budgets (MVEBs) for volatile organic
compounds (VOC) and oxides of nitrogen (NOX) in the Indiana
and Ohio portions of the Cincinnati-Hamilton, Ohio/Kentucky/Indiana
area are adequate for use in transportation conformity determinations.
Indiana submitted the Cincinnati-Hamilton budgets with an 8-hour ozone
attainment demonstration on June 13, 2007. As a result of our finding,
the Indiana and Ohio portions of the Cincinnati-Hamilton, Ohio/
Kentucky/Indiana area must use the MVEBs from the submitted 8-hour
ozone attainment demonstration for future transportation conformity
determinations.

DATES: This finding is effective May 8, 2008.

Radiation Division, United States Environmental Protection Agency,

SUPPLEMENTARY INFORMATION: Throughout this document, whenever ``we'',
``us'' or ``our'' is used, we mean EPA.

Background

    Today's notice is simply an announcement of a finding that we have
already made. On March 6, 2008, EPA Region 5 sent a letter to the
Indiana Department of Environmental Management stating that the 2008
MVEBs for the Indiana and Ohio portion of the Cincinnati-Hamilton,
Ohio/Kentucky/Indiana area, which were submitted with the 8-hour ozone
attainment demonstration, are adequate. Receipt of these MVEBs was
announced on EPA's transportation conformity Web site, and no comments
were submitted. The finding is available at EPA's conformity Web site: 
http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm.
    The adequate 2008 MVEBs, in tons per day (tpd), for VOC and
NOX for the Indiana and Ohio portions of the Cincinnati-
Hamilton, Ohio/Kentucky/Indiana area are as follows:

                                                              2008 MVEB
                                                                (tpd)
------------------------------------------------------------------------
VOC........................................................        72.16
NOX........................................................        18.99
------------------------------------------------------------------------

    Transportation conformity is required by section 176(c) of the
Clean Air Act. EPA's conformity rule requires that transportation
plans, programs, and projects conform to state air quality
implementation plans and establishes the criteria and procedures for
determining whether or not they do conform. Conformity to a State
Implementation Plan (SIP) means that transportation activities will not
produce new air quality violations, worsen existing violations, or
delay timely attainment of the national ambient air quality standards.
    The criteria by which we determine whether a SIP's motor vehicle
emission budgets are adequate for transportation conformity purposes
are outlined in 40 CFR 93.118(e)(4). We have described our process for
determining the adequacy of submitted SIP budgets in our July 1, 2004,
preamble starting at 69 FR 40038, and we used the information in these
resources while making our adequacy determination. Please note that an
adequacy review is separate from EPA's completeness review, and it also
should not be used to prejudge EPA's ultimate approval of the SIP. Even
if we find a budget adequate, the SIP could later be disapproved.
    The finding and the response to comments are available at EPA's
transportation conformity Web site: http://www.epa.gov/otaq/
stateresources/transconf/adequacy.htm.

    Authority: 42 U.S.C. 7401-7671q.
