[FRL-9841-2]
Adequacy Status of the Houston-Galveston-Brazoria, Texas
Reasonable Further Progress and Attainment Demonstration Implementation
Plan for the 1997 8-Hour Ozone Standard; Motor Vehicle Emission Budgets
for Transportation Conformity Purposes
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of adequacy.
-----------------------------------------------------------------------
SUMMARY: EPA is notifying the public that it has found that the motor
vehicle emissions budgets (MVEBs) in the Houston-Galveston-Brazoria,
Texas (HGB) 1997 8-hour ozone standard Reasonable Further Progress
(RFP) and Attainment Demonstration (AD) State Implementation Plan (SIP)
revisions, submitted on May 6, 2013 by the Texas Commission on
Environmental Quality (TCEQ), are adequate for transportation
conformity purposes. As a result of EPA's finding, the HGB area must
use these budgets for future conformity determinations.
DATES: These budgets are effective August 19, 2013.
FOR FURTHER INFORMATION CONTACT: The essential information in this
notice will be available at EPA's conformity Web site: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm. You may also
contact Mr. Jeffrey Riley, Air Planning Section (6PD-L), U.S.
Environmental Protection Agency, Region 6, 1445 Ross Avenue, Dallas,

SUPPLEMENTARY INFORMATION: Throughout this document ``we,'' ``us,'' and
``our'' refers to EPA. The word ``budget(s)'' refers to the mobile
source emissions budget for volatile organic compounds (VOCs) and the
mobile source emissions budget for nitrogen oxides (NOX).

On May 6, 2013, TCEQ submitted as a SIP revision updated MVEBs for
the HGB area. The MVEBs updated the March 2010 HGB 1997 8-hour ozone
RFP and AD SIP revisions to replace the on-road mobile source emissions
inventories for NOX and VOCs based on EPA's MOBILE model
with those based on EPA's MOVES model. This submittal established MVEBs
for the HGB area for the years 2008, 2011, 2014, 2017 and 2018. The
MVEB is the amount of emissions allowed in the state implementation
plan for on-road motor vehicles; it establishes an emissions ceiling
for the regional transportation network. The MVEBs are provided in
Tables 1 and 2:

On May 14, 2013, EPA posted the availability of the HGB area MVEBs
on EPA's Web site for the purpose of soliciting public comments, as
part of the adequacy process. The comment period closed on June 13,
2013, and we received no comments.
Today's notice is simply an announcement of a finding that EPA has
already made. EPA Region 6 sent a letter to TCEQ on July 17, 2013,
finding that the MVEBs in the HGB 1997 8-hour ozone RFP and AD SIPs,
submitted on May 6, 2013 are adequate and must be used for
transportation conformity determinations in the HGB area. This finding
has also been announced on EPA's conformity Web site: http://www.epa.gov/otaq/stateresources/transconf/adequacy.htm.
Transportation conformity is required by section 176(c) of the
Clean Air Act. EPA's conformity rule, 40 Code of Federal Regulations
(CFR) part 93, 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 so. Conformity to a 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 EPA determines whether a SIP's MVEB is
adequate for transportation conformity purposes are outlined in 40 CFR
93.118(e)(4). We have also described the process for determining the
adequacy of submitted SIP budgets in our July 1, 2004, final rulemaking
entitled, ``Transportation Conformity Rule Amendments for the New 8-
hour Ozone and PM2.5 National Ambient Air Quality Standards
and Miscellaneous Revisions for Existing Areas; Transportation
Conformity Rule Amendments: Response to Court Decision and Additional
Rule Changes'' (69 FR 40004). Please note that an adequacy review is
separate from EPA's completeness review, and it should not be used to
prejudge EPA's ultimate approval of the HGB 1997 8-hour ozone RFP and
AD SIP revision submittals. Even if EPA finds the budgets adequate, the
HGB RFP and AD SIP revision submittals could later be disapproved.
Within 24 months from the effective date of this notice, the HGB-
area transportation partners, such as the Houston-Galveston Area
Council, will need to demonstrate conformity to the new MVEBs if the
demonstration has not already been made, pursuant to 40 CFR 93.104(e).
See 73 FR 4419 (January 24, 2008).
