VII. Statutory and Executive Order Reviews
I. Background and Purpose
On December 17, 2004, (69 FR 943; January 5, 2005), EPA designated
the New York-Northern New Jersey-Long Island, NY-NJ-CT area as
nonattainment for the annual National Ambient Air Quality Standards
(NAAQSs) for fine particle pollution or PM2.5. [Airborne
particles less than or equal to 2.5 micrometers in diameter are
considered to be ``fine particles,'' also referred to as
PM2.5.] One year after the April 5, 2005 effective date of
the PM2.5 designations, transportation conformity applies to
this multi-state PM2.5 nonattainment area. Within three
years of final designation, (by April 5, 2008), consistent with section
172(b) of the Clean Air Act, and 40 CFR 51.1002 of the PM2.5
implementation regulations, the States of New Jersey, New York and
Connecticut are required to submit an attainment demonstration and
adopted regulations ensuring that the New York-Northern New Jersey-Long
Island, NY-NJ-CT PM2.5 nonattainment area will attain the
National Ambient Air Quality Standards as expeditiously as practicable.
This PM2.5 attainment demonstration must include motor
vehicle emissions budgets for direct PM2.5 (including re-
entrained road dust and/or highway and transit construction dust if
determined significant contributors), and any PM2.5
precursors determined to be significant (which may include nitrogen
oxides (NOX), volatile organic compounds (VOC), sulfur
dioxide (SO2) and ammonia (NH3)). The SIP must
clearly identify the budgets (motor vehicle emissions budgets) for
transportation conformity purposes.
In the June 8, 2006 Federal Register (71 FR 33305), EPA announced
that the direct PM2.5 and NOX motor vehicle
emissions budgets identified in New Jersey's PM2.5 early
progress state implementation plan (SIP) for the New Jersey portion of
the NY-NJ-CT PM2.5 nonattainment area were adequate for
transportation conformity purposes. As a result of EPA's adequacy
finding, the two metropolitan planning organizations in northern New
Jersey (the North Jersey Transportation Planning Authority (NJTPA) and
the Delaware Valley Regional Planning Commission (DVRPC)) must use the
new 2009 direct PM2.5 and NOX budgets from the
early progress PM2.5 SIP for future conformity
determinations. In addition, with the establishment of adequate motor
vehicle emissions budgets, New Jersey can independently determine
conformity for the New Jersey portion of the NY-NJ-CT PM2.5
nonattainment area and is no longer tied to New York and Connecticut
for transportation conformity determinations. On July 10, 2006, EPA
approved the PM2.5 motor vehicle emissions budgets for
Northern New Jersey into the New Jersey SIP (71 FR 38770).
On April 17, 2007, the Connecticut Department of Environmental
Protection (DEP) submitted a revision to its SIP for establishing early
fine particulate (PM2.5) transportation conformity emission
budgets for the Connecticut portion of the New York-Northern New
Jersey-Long Island, NY-NJ-CT PM2.5 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
PM2.5 nonattainment areas to adopt early motor vehicle
emission budgets that address the annual PM2.5 NAAQSs in
advance of a complete SIP attainment demonstration. This SIP revision
establishes early budgets to simplify the conformity process for
Connecticut Metropolitan Planning Organizations (MPOs) while increasing
the level of protection for Connecticut's citizens during this interim
period before PM2.5 attainment plans are due in April 2008.
The PM2.5 motor vehicle emission budgets for calendar
year 2009 included in Connecticut's April 17, 2007 SIP revision apply
to MPOs in the Connecticut counties of Fairfield and New Haven. Before
these budgets were determined adequate (see Section C below), these
Connecticut MPOs were required to determine conformity jointly with the
New York MPOs included in the NY-NJ-CT PM2.5 nonattainment
area based on a calendar year 2002 interim baseline budget test.
Consistent with a supplemental EPA rulemaking on
[[Page 50061]]
transportation conformity (70 FR 24280; May 6, 2005), Connecticut's
April 17, 2007 SIP revision establishes early motor vehicle budgets for
direct PM2.5 emissions and for emissions of nitrogen oxides
(NOX) [the only PM2.5 precursor found to be
significant at this time for onroad mobile sources]. Since the budgets
have been determined adequate, Connecticut MPOs must demonstrate that
all transportation plans result in emissions of PM2.5 and
NOX that do not exceed the annual 2009 motor vehicle
emissions budget levels.
II. Comparison of Year 2002 Emissions to Year 2009
The total inventory of direct PM2.5 emissions for the
Connecticut portion of the NY-NJ-CT PM2.5 nonattainment Area
is 6,663 tons in calendar year 2002, and is projected to be 6,495 tons
in calendar year 2009. This represents an overall inventory reduction
of 2.5% (168 tons of direct PM2.5 emissions). Table 1,
below, compares calculated year 2002 and year 2009 direct
PM2.5 inventories by source type for the Connecticut portion
of the NY-NJ-CT PM2.5 nonattainment area. Although direct
PM2.5 emissions from area and point sources are projected to
increase by two and eight percent, respectively, emissions from nonroad
and onroad sources are projected to decrease by 13 and 31 percent,
respectively.

The total inventory of NOX emissions for the Connecticut
portion of the NY-NJ-CT PM2.5 nonattainment area is 61,199
tons in calendar year 2002, and projected to be 44,433 tons in calendar
year 2009. This represents an overall inventory reduction of 27%
(16,766 tons of NOX emissions). Table 2, below, compares
calculated 2002 and 2009 annual NOX inventories by source
type for the Connecticut portion of the NY-NJ-CT PM2.5
nonattainment area. Although NOX emissions from area and
point sources are projected to increase by four and seven percent,
respectively, emissions from nonroad and onroad sources are projected
to decrease by 12 and 46 percent, respectively.

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 emissions
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 Connecticut's motor vehicle
emissions budgets on April 19, 2007, by announcing that Connecticut had
submitted an early progress SIP for PM2.5 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 emission 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 May 24, 2007, EPA
notified the Connecticut Department of Environmental Protection (CT
DEP) 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 April 17, 2007, to be adequate for
transportation conformity purposes. EPA New England published a Notice
of Adequacy Federal Register on Tuesday, June 5, 2007 (72 FR 31069),
announcing our May 24, 2007 adequacy determination and making the motor
vehicle emissions budgets effective on June 20, 2007. A copy of EPA's
May 24, 2007 adequacy determination to CT DEP
[[Page 50062]]
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 direct PM2.5 and NOX motor vehicle emissions
budgets as conformity criteria for all 2009 and later evaluation years.
Connecticut's early motor vehicle emissions budgets will insure
progress is made towards achieving and maintaining the PM2.5
NAAQS by limiting the transportation sector to a more restrictive year
2009 level of on-road direct PM2.5 and NOX than
currently allowed by transportation conformity's interim emissions
tests which are based on 2002 emissions in the New York and Connecticut
portions of the nonattainment area. Connecticut will also be able to
evaluate conformity independently and will no longer be required to re-
evaluate conformity whenever a MPO in the New York portion of the New
York-Northern New Jersey-Long Island, NY-NJ-CT PM2.5
nonattainment area triggers conformity. EPA's adequacy determination
for New Jersey's PM2.5 motor vehicle emissions budgets (71
FR 33305; June 8, 2006) already allows New Jersey to independently
determine conformity.
Today's direct final rulemaking approves Connecticut's adequate
2009 direct PM2.5 and NOX motor vehicle emissions
budgets into the Connecticut SIP.
IV. Transportation Conformity Motor Vehicle Emissions Budgets
The early direct PM2.5 and NOX annual motor
vehicle emissions budgets being established are the on-road portion of
the 2009 projections illustrated in Table 3, below, 360 tons per year
for direct PM2.5 and 18,279 tons per year for
NOX. The State of Connecticut Department of Transportation
and Metropolitan Planning Organizations within the Connecticut portion
of the NY-NJ-CT PM2.5 nonattainment area [Council of
Governments of the Central Naugatuck Valley (portion), Greater
Bridgeport and Valley Regional Planning Organizations, Housatonic
Valley Council of Elected Officials (portion), South Central Regional
Council of Governments, and South Western Regional Planning Agency],
shall use these budgets for future transportation conformity
determinations.

V. Basis for Approval
EPA's review of Connecticut's SIP revision concludes that this SIP
revision is consistent with EPA's Transportation Conformity Rule.
Approval of Connecticut'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 now used to evaluate
transportation conformity in the NY-NJ-CT PM2.5
nonattainment area. The projected overall annual inventory reduction in
direct PM2.5 emissions from 2002 to 2009 is approximately
2.5 percent, along with a 27 percent reduction in NOX
emissions. This results from a projected 31 percent reduction in direct
PM2.5 emissions and a 46 percent reduction in NOX
emissions from onroad sources.
Connecticut's projected reduction in direct PM2.5 and
NOX emissions demonstrates progress towards attainment of
the PM2.5 annual standard. Although, the projected reduction
in direct PM2.5 emissions is below 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
Connecticut's early progress SIP should be approved since it will
strengthen the existing SIP. Listed below are several factors that make
Connecticut's SIP package directionally sound.
1. Fairfield County and New Haven County were included in the New
York-Northern New Jersey-Long Island, NY-NJ-CT PM2.5
nonattainment area because of traffic and commuting patterns and other
weighting factors used in EPA's designation process. Connecticut has
never monitored values at or above the annual NAAQSs for
PM2.5.\1\
---------------------------------------------------------------------------
\1\ This SIP is addressing requirements for the annual
PM2.5 standard. Nonattainment of the revised 24-hour
PM2.5 standard (35 micrograms per cubic meter of air
([mu]g/m3)) has not yet been determined.
---------------------------------------------------------------------------
2. There were no monitored violations of EPA's annual
PM2.5 standard in Fairfield and New Haven counties in 2002,
and any reduction in the overall inventory for the two county area
below 2002 levels should help ensure that this level of air quality is
maintained or improved in the future.
3. There is a significant projected tonnage decrease in overall
PM2.5 emissions (168 tons) and NOX emissions
(16,766 tons) by 2009 in comparison to 2002 base year levels.
4. There is a very large percent reduction projected in both
PM2.5 direct and NOX on-road emissions (31% and
46%, respectively) and traffic and commuting patterns were one of the
areas highlighted in the technical support documentation for EPA's
PM2.5 designation decisions.
5. The large reduction in Connecticut's NOX emissions
(27% overall reduction from all inventory sources) may be more
beneficial to transport issues by reducing precursors, than immediate
reduction of direct PM2.5 emissions in Connecticut.
VI. Final Action
EPA is approving the Connecticut SIP revision for establishment of
interim progress for the annual fine particle National Ambient Air
Quality Standard, which was submitted on April 17, 2007. The direct
PM2.5 and annual NOX motor vehicle emissions
budgets being approved are the on-road mobile source 2009 projections
of 360 tons per year of direct PM2.5 and 18,279 tons per
year of NOX. These motor vehicle emissions budgets must be
used to demonstrate that all transportation plans in the Connecticut
portion of the NY-NJ-CT PM2.5 nonattainment area result in
emissions of PM2.5 and NOX that do not exceed the
annual 2009 motor vehicle emissions budget levels.
The EPA is publishing this rule without prior proposal because the
Agency views this as a noncontroversial amendment and anticipates no
adverse
[[Page 50063]]
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 adverse
comments be filed. This action will be effective October 29, 2007
without further notice unless the EPA receives adverse comments by
October 1, 2007.
If the EPA receives such comments, then EPA will publish a document
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. Parties interested in commenting
should do so at this time. If no such comments are received, the public
is advised that this rule will be effective on October 29, 2007 and no
further action will be taken on the proposed rule.
VII. Statutory and Executive Order Reviews
Under Executive Order 12866 (58 FR 51735, October 4, 1993), this
action is not a ``significant regulatory action'' and therefore is not
subject to review by the Office of Management and Budget. For this
reason, this action is also not subject to Executive Order 13211,
``Actions Concerning Regulations That Significantly Affect Energy
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action
merely approves State law as meeting Federal requirements and imposes
no additional requirements beyond those imposed by State law.
Accordingly, the Administrator certifies that this rule will not have a
significant economic impact on a substantial number of small entities
under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because
this rule approves pre-existing requirements under state law and does
not impose any additional enforceable duty beyond that required by
state law, it 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).
This rule also does not have tribal implications because it will
not have a substantial direct effect on one or more Indian tribes, on
the relationship between the Federal Government and Indian tribes, or
on the distribution of power and responsibilities between the Federal
Government and Indian tribes, as specified by Executive Order 13175 (65
FR 67249, November 9, 2000). This action also does not have Federalism
implications because it does not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government, as specified in Executive Order 13132 (64
FR 43255, August 10, 1999), because it merely approves a state rule
implementing a federal standard, and does not alter the relationship or
the distribution of power and responsibilities established in the Clean
Air Act. This rule also is not subject to Executive Order 13045
``Protection of Children from Environmental Health Risks and Safety
Risks'' (62 FR 19885, April 23, 1997), because it approves a state rule
implementing a Federal standard.
In reviewing SIP submissions, EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act. In
this context, in the absence of a prior existing requirement for the
State to use voluntary consensus standards (VCS), EPA has no authority
to disapprove a SIP submission for failure to use VCS. It would thus be
inconsistent with applicable law for EPA, when it reviews a SIP
submission, to use VCS in place of a SIP submission that otherwise
satisfies the provisions of the Clean Air Act. Thus, the requirements
of section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not
impose an information collection burden under the provisions of the
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
The Congressional Review Act, 5 U.S.C. section 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
rule 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 October 29, 2007. Interested
parties should comment in response to the proposed rule rather than
petition for judicial review, unless the objection arises after the
comment period allowed for in the proposal. Filing a petition for
reconsideration by the Administrator of this final rule does not affect
the finality of this rule 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).)
