Approval and Promulgation of Air Quality Implementation Plans; 
Ohio; Dayton-Springfield, Steubenville-Weirton, Toledo, and 
Parkersburg-Marietta; 1997 8-Hour Ozone Maintenance Plan Revision to 
Approved Motor Vehicle Emissions Budgets

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: Under the Clean Air Act (CAA), EPA is approving requests by 
Ohio to revise the 1997 8-hour ozone maintenance air quality state 
implementation plan (SIP) for the Dayton-Springfield area, the Toledo 
area, and the Ohio portions of the Parkersburg-Marietta and 
Steubenville-Weirton, West Virginia-Ohio areas, to replace onroad 
emissions inventories and motor vehicle emissions budgets (budgets) 
with inventories and budgets developed using EPA's Motor Vehicle 
Emissions Simulator (MOVES) emissions model. The Dayton-Springfield 
area consists of Clark, Greene, Miami, and Montgomery Counties. The 
Ohio portion of the Steubenville-Weirton, West Virginia-Ohio area 
consists of Jefferson County, Ohio. The Toledo area consists of Lucas 
and Wood Counties. The Ohio portion of the Parkersburg-Marietta, West 
Virginia-Ohio area consists of Washington County. Ohio submitted the 
SIP revision requests on the following dates: Dayton-Springfield on 
February 11, 2013; Steubenville-Weirton on March 15, 2013; Toledo on 
April 18, 2013; Parkersburg-Marietta on April 26, 2013.

DATES: This direct final rule will be effective December 23, 2013, 
unless EPA receives adverse comments by November 25, 2013. If adverse 
comments are received, EPA will publish a timely withdrawal of the 
direct final rule in the Federal Register informing the public that the 
rule will not take effect.

I. What is EPA approving?

    EPA is approving new MOVES2010a-based onroad emissions inventories 
and budgets for the Dayton-Springfield and Toledo areas, and the Ohio 
portions of the Steubenville-Weirton and Parkersburg-Marietta, West 
Virginia-Ohio 1997 8-hour ozone maintenance areas, that will replace 
MOBILE-based inventories and budgets in the SIP. These areas were 
redesignated to attainment of the 1997 8-hour ozone standard effective 
June 15, 2007 (72 FR 26648, 44784, 27652, 27640), and MOBILE6.2-based 
onroad emissions inventories and budgets were approved in those 
actions. Upon effective date of approval of the MOVES-based budgets, 
they must then be used in future transportation conformity analyses for 
the area as required by section 176(c) of the CAA. See the official 
release of the MOVES2010 emissions model (75 FR 9411-9414) for 
background, and section II.(c) below for details.

II. What is the background for this action?

a. SIP Budgets and Transportation Conformity

    Under the CAA, states are required to submit, at various times, 
control strategy SIP revisions and maintenance plans for nonattainment 
and maintenance areas for a given national ambient air quality standard 
(NAAQS). These SIP revisions and maintenance plans include budgets of 
onroad mobile source emissions for criteria pollutants and/or their 
precursors. Transportation plans and projects ``conform'' to (i.e., are 
consistent with) the SIP when they will not cause or contribute to air 
quality violations, or delay timely attainment of the NAAQS or an 
interim milestone.

b. Prior Approval of Budgets

    EPA previously approved MOBILE6.2-based budgets for the Dayton-
Springfield and Toledo areas, and the Ohio portions of the Parkersburg-
Marietta and Steubenville-Weirton, West Virginia-Ohio 8-hour ozone 
maintenance areas, for volatile organic compounds (VOCs) and nitrogen 
oxides (NOX). The Dayton-Springfield area's ozone 
maintenance plan established 2005 and 2018 budgets. The Toledo area and 
the Ohio portions of the Parkersburg-Marietta and Steubenville-Weirton 
areas' ozone maintenance plans established 2009 and 2018 budgets. These 
budgets demonstrated a reduction in emissions from the monitored 
attainment year.

c. The MOVES Emissions Model

    The MOVES model is EPA's state of the art tool for estimating 
highway emissions. EPA announced the release of MOVES2010 in March 2010 
(75 FR 9411). Use of the MOVES model is required for regional emissions 
analyses for transportation conformity determinations outside of 
California that begin after March 2, 2013.
    MOVES2010a was used to estimate emissions in the areas for the same 
milestone years as the original onroad emissions inventories and 
budgets in the SIP. The Ohio Environmental Protection Agency (OEPA) is 
revising the onroad emissions inventories and budgets using the latest 
planning assumptions, including population and employment updates. In 
addition, newer vehicle registration data has been used to update the 
age distribution of the vehicle fleet. Since future demonstrations of 
conformity will use emissions estimates derived with MOVES, it is 
appropriate to establish benchmarks based on MOVES. The interagency 
consultation group has had extensive consultation on the requirements 
and need for new budgets.

d. Submission of New Budgets Based on MOVES2010a

    Ohio submitted final budgets based on MOVES2010a that cover the 
Dayton-Springfield (submitted February 11, 2013) and Toledo (submitted 
April 18, 2013) areas and the Ohio portions of the Parkersburg-Marietta 
(submitted April 26, 2013) and Steubenville-Weirton (submitted March 
15, 2013), West Virginia-Ohio areas. Ohio did not receive any comments 
for the Toledo, Dayton-Springfield, or Parkersburg-Marietta submittals. 
Ohio received comments requesting clarification on the Steubenville-
Weirton submittal from the West Virginia Division of Air Quality and 
provided responses to the clarifications requested.
    For the Dayton-Springfield area, the new MOVES2010a-based budgets 
are for the years 2005 and 2018 for both VOCs and NOX. For 
the Toledo area and the Ohio portions of the Parkersburg-Marietta and 
Steubenville-Weirton areas, the new MOVES2010a-based budgets are for 
the years 2009 and 2018 for both VOCs and NOX. The budgets 
for these areas are detailed later in this notice. Ohio also provided 
the areas' total emissions, including onroad mobile emissions 
inventories based on MOVES2010a, for the attainment year, the interim 
budget year, and the maintenance year. The combined emissions reduction 
from all sectors between the attainment year and the maintenance year 
is shown as well. Total emissions include point, area, nonroad mobile 
and onroad mobile sources. The total emissions and combined emissions 
reduction from all sectors from 2005 to 2018 for VOC and NOX 
for the area is shown in tables 1 and 2. In tables 1 through 8, for 
onroad emissions of both VOC and NOX for the years noted 
with an asterisk, a 15% safety margin\1\ has been applied to reach the 
values shown.
---------------------------------------------------------------------------

    \1\ The safety margin is achieved by adding a certain percentage 
of emissions, in tons per day, onto the MOVES-based onroad emissions 
budgets. In this case, Ohio chose to add a 15% safety margin to 
their budgets. The safety margin cannot exceed the combined 
emissions reduction for the area.

    The metropolitan planning organizations for these areas added only 
a portion of the overall safety margin available for NOX and 
VOCs to the budgets for the years indicated with an asterisk in tables 
1 through 8. As shown in tables 1 through 8, the submittals demonstrate 
how the areas' emissions decline from the attainment year to maintain 
the 1997 8-hour ozone standard.
    No additional control measures were needed to maintain the 1997 8-
hour ozone standard in the Dayton-Springfield and Toledo areas, and the 
Ohio portions of the Parkersburg-Marietta and Steubenville-Weirton,

[[Page 63392]]

West Virginia-Ohio areas. An appropriate safety margin for 
NOX and VOCs was selected by the interagency consultation 
groups for each area, which consist of representatives from the Federal 
Highway Administration, OEPA, Ohio Department of Transportation, and 
EPA. The submitted budgets for these areas are addressed later in this 
notice.

III. What are the criteria for approval?

    EPA requires that revisions to existing SIPs and budgets continue 
to meet applicable requirements (e.g., reasonable further progress, 
attainment, or maintenance). The SIP must also meet any applicable SIP 
requirements under CAA section 110. In addition, adequacy criteria 
found at 40 CFR 93.118(e)(4) must be satisfied before EPA can find 
submitted budgets adequate and approve them for conformity purposes.
    Areas can revise their budgets and inventories using MOVES without 
revising their entire SIP if (1) the SIP continues to meet applicable 
requirements when the previous motor vehicle emissions inventories are 
replaced with MOVES base year and milestone, attainment, or maintenance 
year inventories, and (2) the state can document that growth and 
control strategy assumptions for non-motor vehicle sources continue to 
be valid and any minor updates do not change the overall conclusions of 
the SIP. The submittals meet this requirement as described below in the 
next section.
    For more information, see EPA's latest ``Policy Guidance on the Use 
of MOVES2010 for SIP Development, Transportation Conformity, and Other 
Purposes'' (April 2012), available online at: www.epa.gov/otaq/stateresources/transconf/policy.htm#models.

IV. What is EPA's analysis of the state's submittals?

a. The Revised Inventories

    The SIP revision requests for these areas' 1997 ozone maintenance 
plans seek to revise only the onroad mobile source inventories. OEPA 
has certified that the control strategies for each area remain the same 
as in the original SIP, and that no other control strategies are 
necessary. OEPA finds that growth and control strategy assumptions for 
non-mobile sources (i.e., area, nonroad, and point) have not changed 
significantly from the original submittals. This is confirmed by the 
monitoring data for the areas, which continue to monitor attainment for 
the 1997 8-hour ozone standard.
    OEPA's submittals confirm that the total emissions in the revised 
SIP (which includes MOVES2010a emissions from mobile sources) as shown 
in tables 1 through 8 demonstrate that emissions in the areas continue 
to decline and remain below the attainment levels.
    Ohio has submitted MOVES2010a-based budgets for the Dayton-
Springfield and Toledo areas, and the Ohio portions of the Parkersburg-
Marietta and Steubenville-Weirton, West Virginia-Ohio areas that are 
clearly identified in the submittals. The budgets are displayed in 
tables 9 through 12.

b. Approvability of the MOVES2010a-based Budgets

    EPA is approving the MOVES2010a-based budgets submitted by Ohio for 
use in determining transportation conformity in the Dayton-Springfield 
and Toledo areas, and the Ohio portions of the Parkersburg-Marietta and 
Steubenville-Weirton, West Virginia-Ohio 1997 ozone maintenance areas. 
EPA evaluated the MOVES-based budgets submitted using the adequacy 
criteria found in 40 CFR 93.118(e)(4) and our in-depth evaluation of 
the state's submittals and SIP requirements.
    Before submitting the revised budgets, OEPA followed all necessary 
conformity procedures. The budgets are clearly identified and precisely 
quantified in the submittals. The budgets, when considered with other 
emissions sources, are consistent with continued maintenance of the 
1997 ozone standard. The budgets are clearly related to the emissions 
inventories and control measures in the SIP. The changes from the 
previous budgets are clearly explained with the change in the model 
from MOBILE6.2 to MOVES2010a and the revised and updated planning 
assumptions. The inputs to the model are detailed in the Appendices to 
the submittals. EPA has reviewed the inputs to the MOVES2010a modeling 
and participated in the consultation process. The Federal Highway 
Administration and the Ohio Department of Transportation have taken a 
lead role in working with the areas' metropolitan planning 
organizations to provide accurate, timely information and inputs to the 
MOVES2010a model runs. The state has documented that growth and control 
strategy assumptions for non-motor vehicle sources (i.e. area, nonroad, 
and point) continue to be valid and any minor updates do not change the 
overall conclusions of the SIP.
    Ohio's submissions confirm that the SIP continues to demonstrate 
maintenance of the 1997 ozone standard because the total emissions in 
the revised SIP (including MOVES2010a emissions for onroad mobile 
sources) continue to decrease from the attainment year to the final 
year of the maintenance plans for these areas, as shown in tables 1 
through 8. As tables 1 through 12 show, the submitted budgets include 
an appropriate margin of safety while still maintaining total emissions 
below the attainment level.
    Based on our review of the SIP and the new budgets provided, EPA 
has determined that the SIP will continue to meet the requirements if 
the revised motor vehicle emissions inventories are

[[Page 63393]]

replaced with MOVES2010a inventories.

c. Applicability of MOBILE6.2-based Budgets

    Upon the effective date of the approval of the revised budgets, the 
state's existing MOBILE6.2-based budgets for these areas will no longer 
be applicable for transportation conformity purposes.

V. What action is EPA taking?

    EPA is approving the submitted onroad mobile source emissions 
inventories and the submitted budgets for the Dayton-Springfield 
(submitted February 11, 2013) and Toledo (submitted April 18, 2013), 
and the Ohio portions of the Parkersburg-Marietta (submitted April 26, 
2013) and Steubenville-Weirton (submitted March 15, 2013), West 
Virginia-Ohio 1997 ozone maintenance plans. We are publishing this 
action without prior proposal because we view this as a 
noncontroversial amendment and anticipate no adverse comments. However, 
in the proposed rules section of this Federal Register publication, we 
are publishing a separate document that will serve as the proposal to 
approve the state plan if relevant adverse written comments are filed. 
This rule will be effective December 23, 2013 without further notice 
unless we receive relevant adverse written comments by November 25, 
2013. If we receive such comments, we will withdraw this action before 
the effective date by publishing a subsequent document that will 
withdraw the final action. All public comments received will then be 
addressed in a subsequent final rule based on the proposed action. EPA 
will not institute a second comment period. Any parties interested in 
commenting on this action should do so at this time. Please note that 
if EPA receives adverse comment on an amendment, paragraph, or section 
of this rule and if that provision may be severed from the remainder of 
the rule, EPA may adopt as final those provisions of the rule that are 
not the subject of an adverse comment. If we do not receive any 
comments, this action will be effective December 23, 2013.

VI. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Order 
12866 (58 FR 51735, October 4, 1993);
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the state, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by December 23, 2013. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. Parties with objections to this direct final rule are 
encouraged to file a comment in response to the parallel notice of 
proposed rulemaking for this action published in the proposed rules 
section of today's Federal Register, rather than file an immediate 
petition for judicial review of this direct final rule, so that EPA can 
withdraw this direct final rule and address the comment in the proposed 
rulemaking. This action may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2).)
