Adequacy Status of the Indianapolis, Indiana Submitted Annual 
Fine Particulate Matter 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 fine particulate 
matter (PM2.5) and oxides of nitrogen (NOx) as a 
precursor to PM2.5 in the Indianapolis, Indiana area are 
adequate for use in transportation conformity determinations. Indiana 
submitted the Indianapolis area budgets with the final PM2.5 
attainment demonstration submittal on June 5, 2008. As a result of our 
finding, the Indianapolis, Indiana area must use the MVEBs from the 
submitted PM2.5 attainment demonstration plan for future 
transportation conformity determinations.

DATES: This finding is effective May 21, 2010.

SUPPLEMENTARY INFORMATION: Throughout this document, whenever ``we'',

    Today's notice is simply an announcement of a finding that we have 
already made. On April 12, 2010, EPA Region 5 sent a letter to the 
Indiana Department of Environmental

[[Page 24944]]

Management stating that the 2002 and 2009 MVEBs for the Indianapolis, 
Indiana area, which were submitted with the state's PM2.5 
attainment demonstration, are adequate. Receipt of these MVEBs was 
announced on EPA's transportation conformity website with a 30 day 
public comment period, 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 2002 and 2009 MVEBs, in tons per year (tpy), for 
PM2.5 and NOX for the Indianapolis, Indiana area 
are as follows:

                          Indianapolis, Indiana
                                      PM2.5 (tpy)          NOX (tpy)
2002............................  842.37............  47,815.51
2009............................  518.43............  28,537.23

    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.
