I. Background and Purpose

    On April 30, 2004 (69 FR 23857), EPA designated as nonattainment 
any area that was violating the 1997 0.08 parts per million (ppm) 8-
hour ozone national ambient air quality standard (NAAQS) based on the 
three most recent years (2001-2003) of air quality data.\1\ Portions of 
Hillsborough, Merrimack, Rockingham and Strafford Counties in New 
Hampshire were designated as a moderate ozone nonattainment area 
(specifically, the Boston-Manchester-Portsmouth (SE), New Hampshire 
area). The rest of New Hampshire was designated as attainment of the 
1997 8-hour ozone NAAQS. (See 40 CFR 81.330.) One year after the June 
15, 2004 effective date of the 8-hour ozone designations, 
transportation and general conformity applied to the nonattainment 
area.
---------------------------------------------------------------------------

    \1\ On March 27, 2008 (73 FR 16436), EPA revised the 8-hour 
ozone standard. The new standard is set at 0.075 ppm. EPA has not 
yet made designations for the 2008 ozone standard.
---------------------------------------------------------------------------

    On March 18, 2008, EPA determined that the Boston-Manchester-
Portsmouth (SE), New Hampshire moderate 8-hour ozone nonattainment area 
had attained the 1997 8-hour ozone NAAQS. (See 73 FR 14387.) This 
determination of attainment was based upon certified ambient air 
monitoring data that show the Boston-Manchester-Portsmouth (SE), New 
Hampshire area had monitored attainment of the 1997 ozone NAAQS since 
the 2002-2004 monitoring period. At present, quality controlled and 
quality assured ozone data for 2008 available in the EPA Air Quality 
System (AQS) database, but not yet certified, show this area continues 
to attain the 1997 ozone NAAQS.
    Under the provisions of EPA's ozone implementation rule (see 40 CFR 
Section 51.918), this determination of attainment suspended the 
requirements for the Boston-Manchester-Portsmouth (SE), New Hampshire 
moderate ozone nonattainment area to submit an attainment 
demonstration, a reasonable further progress plan, section 172(c)(9) 
contingency measures, and any other planning State Implementation Plans 
(SIPs) related to attainment of the 1997 8-hour ozone NAAQS for so long 
as the area continues to attain the 1997 ozone NAAQS. However, this 
action did not constitute a redesignation to attainment under CAA 
section 107(d)(3), because the area did not have an approved 
maintenance plan as required under section 175A of the CAA, nor a 
determination that the area had met the other requirements for 
redesignation. The classification and designation status of the area 
remains moderate nonattainment for the 1997 8-hour ozone NAAQS and 
transportation and general conformity continue to apply.
    On May 28, 2008, the State of New Hampshire submitted a formal 
revision to its SIP containing 8-hour ozone transportation conformity 
emission budgets in tons per summer day, of volatile organic compounds 
(VOC) and oxides of nitrogen (NOX) for the year 2009 for the 
Boston-Manchester-Portsmouth (SE), New Hampshire moderate 8-hour ozone 
nonattainment area. This SIP revision was developed in accordance with 
EPA's transportation conformity rule (69 FR 40028; July 1, 2004), which 
allows states with 8-hour ozone nonattainment areas to adopt early 
motor vehicle emissions budgets (MVEBs) that address the 8-hour ozone 
NAAQSs in advance of a complete SIP attainment demonstration. EPA's 
clean air determination has stayed the state's obligation to prepare an 
8-hour ozone attainment SIP for the 1997 ozone standard. The submitted 
SIP revision establishes budgets to simplify the conformity process for 
New Hampshire Metropolitan Planning Organizations (MPOs) while 
increasing the level of protection for New Hampshire's citizens during 
this interim period before MVEBs are established by an 8-hour ozone 
redesignation plan and its maintenance plan.
    The 8-hour ozone motor vehicle emissions budgets for calendar year 
2009 included in New Hampshire's May 28, 2008 SIP revision cover the 
exact area of the 8-hr ozone nonattainment area. Before these budgets 
were determined adequate (see Section III ``Adequacy Process and SIP 
Approval'' below), the four New Hampshire MPOs in the nonattainment 
area \2\ were required to determine conformity jointly using: (1) The 
2002 interim emissions budgets for that portion of the 8-hour ozone 
area located within the former Manchester 1-hour ozone nonattainment 
area; (2) the 2007 MVEBs for the former Boston-Lawrence-Worcester, 
Southern New Hampshire 1-hour ozone nonattainment area; and, (3) the 
2003 MVEBs for the former Portsmouth-Dover-Rochester, New Hampshire 1-
hour ozone nonattainment area.
---------------------------------------------------------------------------

    \2\ The four metropolitan planning organizations within 8-hr 
ozone nonattainment area are: the Nashua Regional Planning 
Commission; the Rockingham Planning Commission; the Southern New 
Hampshire Planning Commission, and the Strafford Regional Planning 
Commission.
---------------------------------------------------------------------------

II. Comparisons of Year 2002 Emissions to Year 2009

    Inventory information developed for the New Hampshire 2002 Periodic 
Emission Inventory, as well as for 2009 emission projections, was 
prepared on a full county level, not on an individual town basis. 
Interagency consultation between EPA and the New Hampshire Department 
of Environmental Services established that emissions reductions 
calculated for the four full county inventories (point sources, area 
sources, non-road and on-road mobile) would be proportional to 
emissions reductions in the slightly smaller area of the Boston-
Manchester-Portsmouth (SE), New Hampshire, 8-hour ozone nonattainment 
area. However, the actual 2009 MVEBs were developed on a town-by-town 
basis and correspond to the actual area of the 8-hour nonattainment 
area.
    The total inventory of VOC for Hillsborough, Merrimack, Rockingham, 
and Strafford Counties is 231,636 pounds per summer weekday in calendar 
year 2002, and is projected to be 195,536 pounds per summer weekday in 
calendar year 2009. This represents an overall inventory reduction of 
15.58% (36,099 pounds of VOC per summer weekday). Similarly, the total 
inventory of NOX for Hillsborough, Merrimack, Rockingham, 
and Strafford Counties is 280,757 pounds per summer weekday in calendar 
year 2002, and is projected to be 191,074 pounds per summer weekday in 
calendar year 2009. This represents an overall inventory reduction of 
31.94% (89,683 pounds of NOX per summer weekday). On-road 
mobile VOC and NOX 2009 summer weekday emissions are 
expected to decrease significantly from 2002 levels

[[Page 8865]]

(38.13% reduction of VOC and 36.24% reduction of NOX).
    Table 1 below shows that VOC and NOX emissions in the 
southern New Hampshire four counties (Hillsborough, Merrimack, 
Rockingham, and Strafford Counties) are expected to decrease 
considerably from year 2002 to year 2009 for all source categories, 
except area sources.

III. Adequacy Process and SIP Approval

    On March 2, 1999, the United States Court of Appeals for the 
District of Columbia Circuit issued a decision on EPA's third set of 
transportation conformity amendments in response to a case brought by 
the Environmental Defense Fund. The decision held that conformity 
determinations could no longer be based on submitted SIP emission 
budgets, prior to a positive adequacy determination by EPA.
    A May 14, 1999 EPA memorandum from Gay MacGregor to the Regional 
Division Directors provides guidance on how to review budgets for 
adequacy and the process for public comment and notification (posting 
on the Web). The May 14, 1999 guidance is available on EPA's conformity 
Web site at URL address: http://www.epa.gov/otaq/stateresources/transconf/policy/epaguidf.pdf. EPA provided additional guidance in its 
Final Rulemaking on July 1, 2004, (69 FR 40004-40081), ``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; Final Rule.''
    EPA initiated the adequacy process for New Hampshire's motor 
vehicle emissions budgets on June 4, 2008, by announcing that New 
Hampshire had submitted a 2009 MVEB SIP for 8-hour ozone on EPA's Web 
site ``SIP Submissions Currently Under EPA Adequacy Review'' http://www.epa.gov/otaq/stateresources/transconf/currsips.htm. The criteria by 
which EPA determines whether a SIP's motor vehicle emissions budgets 
are adequate for conformity purposes are outlined in 40 CFR 
93.118(e)(4)(i) through 93.118(e)(4)(vi) and 93.118(e)(5). On July 9. 
2008, EPA notified the New Hampshire Department of Environmental 
Services (NH DES) that no comments were received during the thirty day 
public comment period, and that EPA had determined the 2009 motor 
vehicle emissions budgets submitted on May 28, 2008, to be adequate for 
transportation conformity purposes. EPA New England published a Notice 
of Adequacy in the Federal Register on July 28, 2008, (73 FR 43751), 
announcing our July 9, 2008 adequacy determination and making the motor 
vehicle emissions budgets effective on August 12, 2008. A copy of EPA's 
July 9, 2008 adequacy determination to NH DES and the Federal Register 
Notice of Adequacy are both posted in the electronic docket as well as 
on EPA's Web site ``SIP Submissions that EPA has Found Adequate or 
Inadequate,'' at URL address: http://www.epa.gov/otaq/stateresources/transconf/pastsips.htm.
    This positive adequacy determination simplifies the administrative 
process for demonstrating transportation conformity by establishing the 
2009 VOC and NOX motor vehicle emissions budgets as 
conformity criteria for all 2009 and later evaluation years. In 
addition, New Hampshire's 2009 motor vehicle emissions budgets will 
help ensure maintenance of the 8-hour ozone NAAQS by limiting the 
transportation sector to a more restrictive year 2009 level of on-road 
VOC and NOX than currently allowed by transportation 
conformity's interim emission tests which are based on a combination of 
2002 emissions, 2003 1-hour ozone MVEBs and 2007 1-hour ozone MVEBs in 
the 8-hour ozone nonattainment area.
    Today's direct final rulemaking approves New Hampshire's adequate 
2009 8-hour ozone motor vehicle emissions budgets into the New 
Hampshire SIP.

IV. Transportation Conformity Motor Vehicle Emissions Budgets

    The 2009 8-hour ozone motor vehicle emissions budgets being 
approved are the on-road portion of the 2009 emissions projections. As 
illustrated in Table 2, below, the budgets are 15.31 tons per summer 
day for VOC and 28.53 tons per summer day for NOX. The State 
of New Hampshire Department of Transportation and Metropolitan Planning 
Organizations within the nonattainment area shall use these budgets for 
future transportation conformity determinations.

V. Basis for Approval

    EPA's review of New Hampshire's SIP revision concludes that this 
SIP revision is consistent with EPA's Transportation Conformity Rule. 
Approval of New Hampshire's SIP revision is directionally sound since 
it would approve year 2009 motor vehicle emissions budgets which are 
more stringent than the year 2002 baseline emissions, and more 
stringent than the year 2003 and year 2007 1-hour ozone attainment 
demonstration MVEBs now used to evaluate transportation conformity in 
the Boston-Manchester-Portsmouth (SE), New Hampshire 8-hour ozone 
nonattainment area. The projected overall summer weekday inventory 
reduction in VOC emissions from 2002 to 2009 is approximately 15.6 
percent, along with a 31.9 percent reduction in NOX 
emissions. This results from a projected 38 percent reduction in VOC 
emissions and a 36 percent reduction in NOX emissions from 
on-road mobile sources.
    New Hampshire's projected reduction in VOC and NOX 
emissions will help ensure maintenance of the 8-hour ozone standard. 
The projected reduction in both on-road mobile sources and overall 
inventory is greater than the five to ten percent reduction that was 
provided as an example in the July 2004 conformity rule preamble (69 FR 
40019; July 1, 2004). EPA believes that New Hampshire's May 28, 2008 
SIP revision containing 2009 motor vehicle emissions budgets for the 
Southeast New Hampshire moderate 8-hour ozone nonattainment area should 
be approved since it will strengthen the existing SIP. Listed below are 
several factors that make New Hampshire's SIP package directionally 
sound.
    1. On March 18, 2008, (73 FR 14387) the EPA determined that the 
Boston-Manchester-Portsmouth (SE), New Hampshire moderate 8-hour ozone 
nonattainment area had attained the 1997 8-hour NAAQS for ozone.
    2. Certified ambient air monitoring data continues to show that the 
area is monitoring attainment for the 1997 8-hour ozone NAAQS.
    3. There is a very large percent reduction projected in both VOC 
and NOX on-road emissions (38% and 36%, respectively). New 
Hampshire's June 7, 2007 submittal of its 2002 Periodic Inventory shows 
that on-road mobile sources made up 29 percent of the VOC inventory and 
50 percent of the NOX inventory for the 8-hour ozone 
nonattainment area.
    4. The 2009 motor vehicle emissions budgets are more stringent than 
existing 1-hour budgets that the area has been using in conjunction 
with the interim emissions tests.

VI. Final Action

    EPA is approving New Hampshire's 2009 motor vehicle emissions 
budgets for the 8-hour ozone National Ambient Air Quality Standard, 
which were submitted on May 28, 2008, into the New Hampshire SIP. The 
VOC and NOX motor vehicle emissions budgets being approved 
are the on-road mobile source 2009 projections of 15.31 tons per summer 
day of VOC and 28.53 tons per summer day of NOX. These motor 
vehicle emissions budgets must be used to demonstrate that all 
transportation plans and transportation improvement programs in the 
Boston-Manchester-Portsmouth (SE), New Hampshire, 8-hour ozone 
nonattainment area result in emissions of VOC and NOX that 
do not exceed the 2009 motor vehicle emissions budgets.
    The EPA is publishing this action without prior proposal because 
the Agency views this as a noncontroversial amendment and anticipates 
no adverse comments. However, in the proposed rules section of this 
Federal Register publication, EPA is publishing a separate document 
that will serve as the proposal to approve the SIP revision should 
relevant adverse comments be filed. This rule will be effective April 
28, 2009 without further notice unless the Agency receives relevant 
adverse comments by March 30, 2009.
    If the EPA receives such comments, then EPA will publish a notice 
withdrawing the final rule and informing the public that the rule will 
not take effect. All public comments received will then be addressed in 
a subsequent final rule based on the proposed rule. The EPA will not 
institute a second comment period on the proposed rule. All parties 
interested in commenting on the proposed rule should do so at this 
time. If no such comments are received, the public is advised that this 
rule will be effective on April 28, 2009 and no further action will be 
taken on the proposed rule. 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.

VII. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Act 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 Clean Air Act. 
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 Clean Air Act; 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.

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 Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by April 28, 2009. 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. This action may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2).)
