Transportation Conformity Purposes
Environmental Protection
Agency (EPA).
ACTION: Notice of adequacy
determination.
AGENCY:
In this notice, the EPA is
notifying the public of its finding that
the motor vehicle emissions budgets
(MVEBs) for particulate matter with an
aerodynamic diameter of a nominal 10
microns or less (PM10), nitrogen oxides
(NOx), and volatile organic compounds
(VOC) for the years 2008, 2015 and 2023
in the Northern Ada County PM10 State
Implementation Plan, Maintenance
Plan: Ten-Year Update (Maintenance
Plan Update) are adequate for
transportation conformity purposes. The
Maintenance Plan Update was
submitted to the EPA by the State of
Idaho Department of Environmental

Quality (IDEQ or the State) on March 11,
2013, with a clarification to the MVEB
submitted on April 16, 2013. As a result
of this finding, the Community Planning
Association of Southwest Idaho, the
Idaho Transportation Department and
the U.S. Department of Transportation
will be required to use these MVEBs for
future transportation conformity
determinations.
DATES: This finding is effective June 21,
2013.
FOR FURTHER INFORMATION CONTACT: The
finding will be available at the EPA’s
conformity Web site: https://
www.epa.gov/otaq/stateresources/

SUPPLEMENTARY INFORMATION: This
action provides notice of the EPA’s
adequacy finding regarding the MVEBs
in the Maintenance Plan Update in
Northern Ada County. The EPA’s
finding was made pursuant to the
adequacy review process for
implementation plan submissions
delineated at 40 CFR 93.118(f)(1) under
which the EPA reviews the adequacy of
an implementation plan submission
prior to the EPA’s final action on the
implementation plan.
The IDEQ submitted the Maintenance
Plan Update to the EPA on March 11,
2013, with a clarification to the MVEBs
submitted on April 16, 2013. Pursuant
to 40 CFR 93.118 (f)(1), the EPA notified
the public of its receipt of this plan that
would be reviewed for an adequacy
determination on the EPA’s Web site
and requested public comment by no
later than May 15, 2013. The EPA
received no comments on the plan
during that comment period. As part of
our review, we also reviewed comments
submitted to the IDEQ during the State’s
public hearing process and the State’s
response to those comments. One
comment related to the MVEBs was
submitted during the State’s public
hearing process. The commenter
requested an explanation of the
differences in the State’s current and
previous PM10 emission budgets, and a
justification for the State’s reliance on
an emission factor that differed from the
factor previously relied-upon in the
State’s emission budget. The EPA finds
that the State addressed the discrepancy
identified by the commenter and
adequately explained the derivation of
the State’s current PM10 emission
budget.
The EPA Region 10 sent a letter to the
IDEQ on May 17, 2013 (adequacy letter),
PO 00000
Frm 00065
Fmt 4703
Sfmt 9990
subsequent to the close of the EPA
comment period, stating that the EPA
found the new MVEBs in the submitted
Maintenance Plan Update to be
adequate for use in transportation
conformity. A copy of the adequacy
letter and its enclosure is available at
the EPA’s conformity Web site: https://
www.epa.gov/otaq/stateresources/
transconf/adequacy.htm. The new
MVEBs that the EPA determined to be
adequate for purposes of transportation
conformity are listed in the following
table.

Transportation conformity is required
by section 176(c) of the Clean Air Act.
The EPA’s conformity rule requires
transportation plans, programs, and
projects to conform to state
implementation plans (SIPs) and
establishes the criteria and procedures
for determining whether or not they do.
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 minimum criteria by which we
determine whether a SIP’s MVEBs are
adequate for conformity purposes are
specified at 40 CFR 93.118(e)(4). The
EPA’s analysis of how the State’s
submission satisfies these criteria is
found in the adequacy letter. The EPA’s
MVEB adequacy review is separate from
the EPA’s SIP completeness review and
it also should not be used to prejudge
the EPA’s ultimate approval of the SIP.
Even if we find the budget adequate, the
SIP could later be disapproved.
