Approval and Promulgation of Air Quality Implementation Plans;
New Hampshire; Manchester and Nashua Carbon Monoxide Limited
Maintenance Plans
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing to
approve a State Implementation Plan (SIP) revision submitted by the
State of New Hampshire. This SIP revision establishes carbon monoxide
(CO) limited maintenance plans for the City of Manchester, New
Hampshire and the City of Nashua, New Hampshire. As part of its limited
maintenance plan, New Hampshire will continue year-round CO monitoring
at the Londonderry Moose Hill station in Londonderry, New Hampshire
with triggers to reestablish CO monitoring sites in Manchester and
Nashua if elevated CO levels are recorded in Londonderry. Future carbon
monoxide transportation conformity evaluations for Manchester and
Nashua would for the length of their limited maintenance plans be
considered to satisfy the regional emissions analysis and ``budget
test'' requirements. This action is being taken under the Clean Air
Act.

I. Background and Purpose
The City of Manchester, New Hampshire (Manchester) and the City of
Nashua, New Hampshire (Nashua) were designated nonattainment by EPA for
carbon monoxide on March 3, 1978 (43 FR 8962) and April 11, 1980 (45 FR
24869), respectively. The current National Ambient Air Quality Standard
(NAAQS) for CO is 9.0 parts per million (ppm) for an 8-hour average
concentration and 35 ppm for a 1-hour concentration, not to be exceeded
more than once per calendar year. In 1991, following passage of the
Clean Air Act Amendments of 1990 (CAA), both cities were designated
``nonattainment'' and ``not classified'' (November 6, 1991; 56 FR
56694) although ambient monitoring showed NAAQS attainment had been
achieved by that time. In February 1999, the State of New Hampshire
submitted a formal CO redesignation request and a CO maintenance plan
for Manchester and Nashua. Effective January 29, 2001 (November 29,
2000; 65 FR 71060), EPA redesignated Manchester and Nashua from
nonattainment to attainment for CO and approved New Hampshire's CO
maintenance plan.
On May 30, 2007, the New Hampshire Department of Environmental
Services (NH DES) submitted a SIP revision to EPA that contained
modifications to their CO maintenance plan for the Nashua CO
maintenance area. These modifications which were approved by EPA
through a direct final rule (September 10, 2007; 72 FR 51564) changed
the triggering mechanism by which contingency measures would be
implemented in Nashua, and allowed the State to discontinue CO
monitoring in the Nashua maintenance area. New Hampshire would rely on
data from the CO monitor in Manchester to determine when, and if,
monitoring would be reestablished in the Nashua maintenance area, and,
in some circumstances, when contingency measures would be triggered in
the Nashua maintenance area. At the time of the SIP revision approval,
CO concentrations measured in Nashua were below the NAAQS for nearly 20
years, and maximum measured concentrations were less than 50% of the 9
parts per million 8-hour CO standard.
On August 1, 2012, the NH DES submitted a limited maintenance plan
SIP revision for the remainder of Manchester and Nashua's second ten-
year maintenance plans (January 29, 2011 to January 29, 2021). The
revision also requests discontinuance of CO monitoring in Manchester to
be replaced by a CO monitoring station in Londonderry, New Hampshire
(mid-way between Manchester and Nashua). These revisions are the
subject of today's notice of proposed rulemaking.
Under the CO limited maintenance plan New Hampshire would continue
to implement strategies that have helped reduce CO emissions in
Manchester and Nashua. These strategies include: New Hampshire's
Vehicle Inspection/Maintenance On Board Diagnostic (OBD II) program;
Vehicle Miles Travel reductions (implement congestion and emission
reduction programs such as traffic signal coordination, increased mass
transit, RideShare, anti-idling and other traffic mitigation measures);
and Low Emissions Vehicles Standards. New Hampshire has also committed
to continuing CO monitoring in Londonderry with triggers to reestablish
CO monitoring in Manchester and Nashua. In the event monitored carbon
monoxide concentrations reach or exceed the limited maintenance
eligibility criteria of 7.65 parts per million, then the area would
revert to a full maintenance plan.
II. Criteria for Limited Maintenance Plan Designation
A. EPA Guidance
For the Manchester and Nashua areas, NH DES's SIP revision uses
EPA's limited maintenance plan approach, as detailed in the EPA
guidance memorandum, ``Limited Maintenance Plan Option for
Nonclassifiable CO Nonattainment Areas'' from Joseph Paisie, Group
Leader, Integrated Policy and Strategies Group, Office of Air Quality
and Planning Standards (OAQPS), dated October 6, 1995, (the Paisie
Memorandum, [a copy of which is included in the Docket as part of the
States' SIP revision]). Pursuant to this approach EPA will consider the
maintenance demonstration satisfied for ``not classified'' areas if the
monitoring data show the design value is at or below 7.65 parts per
million, or 85 percent of the level of the 8-hour carbon monoxide
NAAQS. The design value must be based on eight consecutive quarters of
data. For such areas, there is no requirement to project emissions of
air quality over the maintenance period. EPA believes if the area
begins the maintenance period at, or below, 85 percent of the CO 8 hour
NAAQS, the applicability of ``Prevention of Significant Deterioration''
(PSD), the control measures already in the SIP, and Federal measures
(including the Federal Motor Vehicle Control Program emission
standards, limiting CO emissions), should provide adequate assurance of
maintenance over the initial 10-year maintenance period. In addition,
the design value for the area must continue to be at or below 7.65 ppm
until the time of final EPA action on the redesignation.
The 8-hour CO design values for each of New Hampshire's CO
maintenance areas are summarized in Table 1 below. In all cases, 8-hour
design values are significantly less than the 7.65 ppm threshold
specified in EPA guidance, thus making each area potentially eligible
for the limited maintenance plan option.

B. Emission Inventory
Consistent with EPA's guidance for limited maintenance plans, the
State developed an attainment emissions inventory to identify the level
of emissions in Hillsborough County, which includes Manchester and
Nashua, sufficient to attain the NAAQS. (See Table 2 below.) The State
also developed an attainment emissions inventory identifying the level
of emissions statewide associated with attaining and maintaining the CO
NAAQS. (See Table 3 below.) These inventories are consistent with EPA's
most recent guidance on emissions inventories for nonattainment areas
available at the time, and they document a downward trend in CO
emissions during the time period associated with the monitoring data
achieving attainment and continued maintenance of the CO NAAQS.

C. Demonstration of Maintenance
The maintenance demonstration requirement is considered to be
satisfied if the monitoring data show that the area is meeting the air
quality criteria for limited maintenance areas (7.65 ppm or 85% of the
CO NAAQS). There is no requirement to project emissions over the
maintenance period. The EPA believes since the area is below 85 percent
of exceedance levels, the air quality along with the continued
applicability of PSD requirements, any control measures already in the
SIP, and Federal measures, should provide adequate assurance of
maintenance over the remainder of the 10-year maintenance period.
When EPA approves a limited maintenance plan, EPA is concluding
that an emissions budget may be treated as essentially not constraining
for the length of the maintenance period because it is unreasonable to
expect that such an area will experience so much growth in that period
that a violation of the CO NAAQS would result.
D. Monitoring Network and Verification of Continued Attainment
In its SIP revision, NH DES commits to continue CO monitoring year-
round at the Londonderry Moose Hill station in Londonderry. NH DES
worked closely with EPA to carefully select this site due to its
central proximity to Manchester and Nashua. The Londonderry Moose Hill
Station came online on January 1, 2011 as a National Core (NCore)
multi-pollutant monitoring station measuring a wide variety of
pollutants. The Londonderry station measures fine particulate
(PM2.5), nitrogen oxides, ozone, sulfur dioxide and carbon
monoxide, in addition to wind speed, wind direction, and relative
humidity.
III. Contingency Measures
Section 175A(d) of the Act requires that a maintenance plan include
contingency provisions, as necessary, to promptly correct any violation
of the NAAQS that occurs after redesignation of the area. Under section
175A(d), contingency measures do not have to be
[[Page 77631]]
fully adopted at the time of redesignation. However, the contingency
plan is considered to be an enforceable part of the SIP and should
ensure that the contingency measures are adopted expeditiously once
they are triggered by a specified event. Previously implemented
contingency measures and emissions reductions strategies in New
Hampshire have proven successful, and will be continued through the
maintenance period. These include: Vehicle Inspection/Maintenance (I/
M); vehicle miles traveled reductions; and other emissions reduction
programs.
Vehicle Inspection/Maintenance (I/M)--EPA approved New Hampshire's
I/M program on January 25, 2013 (78 FR 5292). In its CO maintenance
plan SIP revision, NH DES commits to continued implementation of this
program.
Vehicle Miles Traveled reductions--In its CO maintenance plan SIP
revision, NH DES commits to continue working with the NH Department of
Transportation and regional Metropolitan Planning Organizations (MPOs)
to identify effective congestion and emission reduction project and
programs such as traffic signal coordination, increased mass transit,
RideShare, anti-idling and other traffic management strategies.
Other emissions reductions programs--NH DES and local MPOs are
actively promoting low emissions vehicles and emissions reductions
strategies such as anti-idling programs and park & ride lot
construction as part of their long range transportation plans.
IV. State Commitments
New Hampshire will monitor CO levels using the Londonderry Moose
Hill station and emissions inventories. Because New Hampshire proposes
to discontinue monitoring CO in Manchester, it will adopt a more
stringent contingency threshold or ``trigger'' than indicated in the
2007 SIP revision. In the event the second highest CO concentration in
any calendar year monitored in Londonderry reaches 50 percent of the
Federal 1-hour or 8-hour NAAQS for CO, New Hampshire will, within six
months of recording such concentrations, reestablish the CO monitoring
site in Manchester consistent with EPA siting criteria, and resume
analyzing and reporting those data. If the reestablished Manchester CO
monitor measures a violation of the either the Federal 1-hour or 8-hour
NAAQS for CO, contingency measures will be implemented in Manchester
and Nashua. Contingency measures in Nashua would cease once a
reestablished CO monitor in Nashua shows that the area is in attainment
of the CO standard.
V. Conformity
Section 176(c) of the Act defines transportation conformity as
conformity to the SIP's purpose of eliminating or reducing the severity
and number of violations of the NAAQS and achieving expeditious
attainment of such standards. The Act further defines transportation
conformity to mean that no Federal transportation activity will: (1)
Cause or contribute to any new violation of any standard in any area;
(2) increase the frequency or severity of any existing violation of any
standard in any area; or (3) delay timely attainment of any standard or
any required interim emission reductions or other milestones in any
area. The Federal Transportation Conformity Rule, 40 CFR part 93
subpart A, sets forth the criteria and procedures for demonstrating and
assuring conformity of transportation plans, programs and projects
which are developed, funded or approved by the U.S. Department of
Transportation, and by metropolitan planning organizations or other
recipients of funds under title 23 U.S.C. or the Federal Transit Laws
(49 U.S.C. Chapter 53). The transportation conformity rule applies
within all nonattainment and maintenance areas. As prescribed by the
transportation conformity rule, once an area has an applicable State
Implementation Plan with motor vehicle emissions budgets, the expected
emissions from planned transportation activities must be consistent
with (``conform to'') such established budgets for that area.
According to EPA's guidance on limited maintenance plans, in the
case of the Manchester and Nashua New Hampshire CO limited maintenance
plan areas, the emissions budgets may be treated as essentially not
constraining for the length of the maintenance period as long as the
area continues to meet the limited maintenance criteria, because there
is no reason to expect that these areas will experience so much growth
in that period that a violation of the CO NAAQS would result. In other
words, emissions from on-road transportation sources need not be capped
for the maintenance period because it is unreasonable to believe that
emissions from such sources would increase to a level that would
threaten the air quality in this area for the duration of this
maintenance period. Therefore, for limited maintenance plan CO
maintenance areas, all Federal actions that require conformity
determinations under the transportation conformity rule are considered
to satisfy the regional emissions analysis and ``budget test''
requirements in 40 CFR 93.118 of the rule.
Since limited maintenance plan areas are still maintenance areas,
however, transportation conformity determinations are still required
for transportation plans, programs and projects. Specifically, for such
determinations, transportation plans, transportation improvement
programs, and projects must still demonstrate that they are fiscally
constrained (40 CFR part 108) and must meet the criteria for
consultation and Transportation Control Measure (TCM) implementation in
the conformity rule (40 CFR 93.112 and 40 CFR 93.113, respectively). In
addition, projects in limited maintenance areas will still be required
to meet the criteria for CO hot spot analyses to satisfy ``project
level'' conformity determinations (40 CFR 93.116 and 40 CFR 93.123)
which must incorporate the latest planning assumptions and models that
are available. All aspects of transportation conformity (with the
exception of satisfying the emission budget test) will still be
required.
If the Manchester or Nashua CO attainment areas monitor CO
concentrations at or above the limited maintenance eligibility criteria
or 7.65 parts per million, then that maintenance area would no longer
qualify for a limited maintenance plan and would revert to a full
maintenance plan. In this event, the limited maintenance plan would
remain applicable for conformity purposes only until the full
maintenance plan is submitted and EPA has found its motor vehicle
emissions budgets adequate for conformity purposes or EPA approves the
full maintenance plan SIP revision. Any required new conformity
determinations could not be made until there is an adequate budget or
approved full maintenance plan. At that time, regional emissions
analyses would resume as a transportation conformity criteria.
VI. Proposed Action
EPA is proposing to approve conversion of the Manchester and Nashua
current carbon monoxide maintenance plans to a limited maintenance plan
for the remainder of the City of Manchester, and the City of Nashua,
New Hampshire CO maintenance plans which terminate on January 29, 2021.
EPA is proposing to approve replacement of the CO air quality
monitoring in Manchester with carbon monoxide monitoring at the
Londonderry Moose Hill station in Londonderry, New Hampshire with
triggers to reestablish CO monitoring
[[Page 77632]]
sites in Manchester and Nashua if elevated CO levels are recorded in
Londonderry.
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 proposed 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 proposed 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.
