I. Background and Purpose
On May 30, 2007, the State of New Hampshire submitted a formal
revision to its State Implementation Plan (SIP). The SIP revision
consists of a minor modification to the carbon monoxide (CO)
maintenance plan for Nashua, New Hampshire. (A redesignation request
and a maintenance plan for the Nashua CO nonattainment area were
approved by EPA on November 29, 2000 (65 FR 71060).) The modification
changes the triggering mechanism which will be used by the State to
determine if contingency measures need to be implemented in Nashua. The
end result of this action will be to allow the discontinuation of CO
monitoring in the Nashua maintenance area.
II. What action is EPA taking?
EPA is approving revisions to the Nashua carbon monoxide
maintenance plan submitted by the State of New Hampshire on May 30,
2007. Specifically, EPA is approving the State's modification of the
portion of the maintenance plan used to determine when contingency
measures need to be triggered to reduce CO concentrations in Nashua.
New Hampshire's SIP revision and EPA's evaluation of this SIP
revision are discussed below. Additional details are also provided in a
memorandum dated July 27, 2007, entitled ``Technical Support Document
for Revision to the Carbon Monoxide Maintenance Plan for Nashua, New
Hampshire,'' (TSD). The TSD and New Hampshire's submittal are available
in the docket supporting this action.
III. Summary of SIP Revision
On May 30, 2007, the New Hampshire Department of Environmental
Services submitted a SIP revision to EPA that contains a modification
to their CO maintenance plan for the Nashua CO maintenance area. The
modifications to the maintenance plan change the triggering mechanism
by which contingency measures would be implemented and will allow the
State to discontinue CO monitoring in the Nashua maintenance area. CO
concentrations measured in Nashua have been below the National Ambient
Air Quality Standard (NAAQS) for nearly 20 years, and in recent years,
maximum measured concentrations have been less than 50% of the 9 parts
per million 8-hour CO standard. In this SIP revision, the State of New
Hampshire is establishing an alternative triggering mechanism, which
will rely on CO data from a nearby CO monitor in Manchester, New
Hampshire.
Section 6.5.3 of the State's currently approved CO maintenance
plan, entitled ``Selection of a Nonattainment Indicator,'' includes a
triggering mechanism based on levels at the CO monitor in Nashua. Under
the current maintenance plan, contingency measures in Nashua are
triggered when a violation of the CO NAAQS is measured in Nashua. Under
the revised maintenance plan, New Hampshire will rely on data from the
Manchester CO monitor to determine when and if monitoring will be
reestablished in the Nashua maintenance area, and, in some
circumstances, when contingency measures will be triggered in the
Nashau maintenance area. The revised maintenance plan language is found
below:
``For the purposes of this plan, New Hampshire will be
discontinuing CO monitoring in Nashua upon EPA approval of this
revised plan. New Hampshire DES will continue to collect and review
CO monitoring data from nearby Manchester, NH on an on-going basis.
In the event the second highest CO concentration in any calendar
year monitored in Manchester reaches 75 percent of the federal 1-
hour or 8-hour national ambient air quality standard for CO, New
Hampshire will, within 9 months of recording such concentrations,
re-establish a CO monitoring site in Nashua consistent with EPA
siting criteria, and resume analyzing and reporting those data. New
Hampshire will continue to commit to implement its contingency
program in Nashua in the event that a CO violation (the `contingency
trigger') is monitored at the re-established Nashua monitoring site
at any time during the maintenance period and to consider one or
more of the other EPA-approved measures listed in Section 6.5.2 if
necessary to reduce CO levels.
If the Manchester CO monitor measures a violation of either the
federal 1-hour or 8-hour NAAQS for CO, the contingency measures in
Section 6.5.2 will be implemented in Nashua as well, until a re-
established Nashua CO monitor shows that the area is attainment of
the CO standard.
When implementing contingency measures, New Hampshire will
review and implement the measures necessary to remedy the violation,
including transportation control measures (TCM) or other additional
vehicle or fuel controls.''
IV. EPA's Evaluation of the SIP Revision
EPA agrees that the mechanism described above represents an
acceptable contingency triggering mechanism for the Nashua CO
maintenance plan. Approval of this revised triggering mechanism will
allow New Hampshire DES to discontinue monitoring in the Nashua area,
which we believe is appropriate for this area which is currently
measuring concentrations well below the existing 1-hour and 8-hour CO
NAAQS. Under this plan, we believe air quality goals can be maintained,
and State monitoring resources conserved.
On October 17, 2006, EPA published a final monitoring rule revising
the minimum monitoring requirements. That rule explicitly recognized
that, in some cases where measured levels of pollutants are low,
shutting down certain CO monitors may be allowed. The rule, however,
also explicitly provides that if a monitor is the only monitor in the
area, and it serves as a trigger to implement a contingency measure in
an EPA-approved maintenance plan, the maintenance plan would need to be
revised, and the trigger replaced. (See 71 FR 61250 and 71 FR 61301.)
As described above, this action is approving a change to the
mechanism that New Hampshire will use to determine when contingency
measures need to be triggered to reduce CO concentrations in Nashua.
Previously, the State would implement a contingency measure based on
concentrations of CO monitored in Nashua. In light of the fact that
Nashua CO concentrations have been well below the standard for some
time, the State is looking to conserve resources. New Hampshire DES
wants to use its CO monitor in Manchester, a nearby city, to aid in
determining if Nashua has
[[Page 51566]]
a CO problem. Nashua and Manchester (both in Hillsborough County) are
less than 20 miles apart, have similar populations, and both have had
CO concentrations similar to each other for years. (The TSD provides a
comparison of the data collected at the Nashua and Manchester CO
monitors over the past several decades.) Both cities were designated
nonattainment in 1990 for CO ``by operation of law,'' though both had
design values below the standard at that time. In both cases, only the
city itself was designated nonattainment since data did not support an
expansion of the nonattainment area. Both cities were redesignated to
attainment in 2000, and both have measured CO concentrations well below
the standard since that time.
In order to conserve resources, the State is seeking to discontinue
monitoring in Nashua since current air quality levels do not warrant
the additional expense of running a CO monitor in this area. The State
has committed to continue CO monitoring in Manchester, and will
reestablish CO monitoring in Nashua if air quality in Manchester
degrades significantly. Starting in the early 1970s, EPA has set
national standards that have considerably reduced emissions of CO and
other pollutants from motor vehicles, including tailpipe emissions, new
vehicle technologies, and clean fuels programs. Because of this, EPA
believes that it is unlikely that either maintenance area will exceed
the CO NAAQS again. Thus, we believe that the revisions that New
Hampshire has made to its maintenance plan will continue to protect the
citizens of New Hampshire from high CO concentrations, and also
conserve resources.
V. Final Action
EPA is approving revisions to the Nashua CO maintenance plan
submitted by the State of New Hampshire on May 30, 2007. Specifically,
EPA is approving the State's request to modify the portion of the
maintenance plan used to determine when contingency measures need to be
implemented in Nashua. As described in more detail above, the State
will shut down the Nashua CO monitor and rely on data from the CO
monitor in Manchester to determine when and if monitoring will be
reestablished in the Nashua maintenance area, and, in some
circumstances, when contingency measures will be triggered in the
Nashua maintenance area.
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
November 9, 2007 without further notice unless the Agency receives
relevant adverse comments by October 10, 2007.
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 November 9, 2007 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.
VI. 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.
[[Page 51567]]
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 November 9, 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).)

(d) Approval--On May 30, 2007, the New Hampshire Department of
Environmental Services submitted a modification to the Nashua
maintenance plan approved in paragraph (c) of this section. New
Hampshire will not conduct CO monitoring in Nashua, but instead commits
to continue to collect and review CO monitoring data from nearby
Manchester, NH on an on-going basis. In the event the second highest CO
concentration in any calendar year monitored in Manchester reaches 75
percent of the federal 1-hour or 8-hour national ambient air quality
standard for CO, New Hampshire will, within 9 months of recording such
concentrations, re-establish a CO monitoring site in Nashua consistent
with EPA siting criteria, and resume analyzing and reporting those
data. New Hampshire commits to implement its contingency program in
Nashua in the event that a CO violation is monitored at the re-
established Nashua monitoring site at any time during the maintenance
period. If the 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 Nashua as well, until a re-established CO monitor in
Nashua shows that the area is in attainment of the CO standard.
