II. Background A. Billings CO Maintenance Plan Under the Clean Air Act (CAA) Amendments of 1990, the Billings area was designated as nonattainment and classified as a ‘‘not classified’’ CO area. This was because the area had been designated as nonattainment before November 15, 1990, but had not violated the CO NAAQS in 1988 and 1989 (56 FR 56694, November 6, 1991). On February 9, 2001, the Governor of Montana submitted to us a request to redesignate the Billings CO nonattainment area to attainment for the CO NAAQS. Along with this request, the Governor submitted a CAA section 175A(a) maintenance plan which demonstrated that the area would maintain the CO NAAQS for the first 10 years following our approval of the redesignation request. We approved the State’s redesignation request and 10year maintenance plan on February 21, 2002 (67 FR 7966). E:\FR\FM\02DEP1.SGM 02DEP1 71371 Federal Register / Vol. 79, No. 231 / Tuesday, December 2, 2014 / Proposed Rules Eight years after an area is redesignated to attainment, CAA section 175A(b) requires the state to submit a subsequent maintenance plan to EPA, covering a second 10-year period.1 This second 10-year maintenance plan must demonstrate continued compliance with the NAAQS during this second 10-year period. To fulfill this requirement of the CAA, the Governor of Montana’s designee submitted the second 10-year update of the Billings CO maintenance plan (hereafter; ‘‘revised Billings Maintenance Plan’’) to us on July 13, 2011. With this action, we are proposing approval of the revised Billings Maintenance Plan. The 8-hour CO NAAQS—9.0 parts per million (ppm)—is attained when such value is not exceeded more than once a year. 40 CFR 50.8(a)(1). The Billings area has attained the 8-hour CO NAAQS from 1988 to the present. In October 1995, EPA issued guidance that provided nonclassifiable CO nonattainment areas the option of using a less rigorous ‘‘limited maintenance plan’’ (LMP) option to demonstrate continued attainment and maintenance of the CO NAAQS.2 According to this guidance, areas that can demonstrate design values (2nd highest max) at or below 7.65 ppm (85% of exceedance levels of the 8-hour CO NAAQS) for eight consecutive quarters qualify to use an LMP. The area qualified for and used EPA’s LMP option for the first 10-year Billings CO maintenance plan (67 FR 7966, February 21, 2002). For the revised Billings Maintenance Plan the State again used the LMP option to demonstrate continued maintenance of the CO NAAQS in the Billings area. We have determined that the Billings area continues to qualify for the LMP option because the maximum design value for the most recent eight consecutive quarters with certified data at the time the State adopted the plan (years 2008 and 2009) was 2 ppm.3 mstockstill on DSK4VPTVN1PROD with PROPOSALS B. Alternative CO Monitoring Strategy Along with the revised Billings Maintenance Plan, the State submitted a CO maintenance plan for the Great Falls, Montana maintenance area, and 1 In this case, the initial maintenance period extended through 2012. Thus, the second 10-year period extends through 2022. 2 Memorandum ‘‘Limited Maintenance Plan Option for Nonclassifiable CO Nonattainment Areas’’ from Joseph W. Paisie, Group Leader, EPA Integrated Policy and Strategies Group, to Air Branch Chiefs, October 6, 1995. 3 See Table 2 below. Additionally, according to the LMP guidance, an area using the LMP option must continue to have a design value ‘‘at or below 7.65 ppm until the time of final EPA action on the redesignation.’’ Table 2, below, demonstrates that the area meets this requirement. VerDate Sep<11>2014 16:20 Dec 01, 2014 Jkt 235001 an alternative strategy for monitoring continued attainment of the CO NAAQS in all of the State’s CO maintenance areas on July 13, 2011.4 The State submitted the alternative monitoring strategy to conserve resources by discontinuing the gaseous CO ambient monitors in both the Billings and Great Falls CO maintenance areas. In place of the gaseous ambient monitors, the State’s alternative method relies on rolling 3-year Average Daily Traffic (ADT) vehicle counts collected from permanent automatic traffic recorders in each maintenance area. We commented on the State’s ‘‘Alternative Monitoring Strategy,’’ and the State submitted to us a revised version of the strategy which incorporated our comments on June 22, 2012. The State’s June 22, 2012 Alternative Monitoring Strategy replaced the version submitted on July 13, 2011. III. EPA’s Evaluation of Montana’s Alternative Monitoring Strategy in Billings Since 2002, no Billings CO monitor has registered a design value greater than 4.4 ppm, which is roughly half of the NAAQS. Further, since 2006, no Billings monitor has registered a design value greater than 2.2 ppm, roughly 25% of the NAAQS.5 Citing these consistently low monitor values, and expressing a desire to conserve monitoring resources, the State has requested to discontinue CO monitoring in Billings and instead use an alternative strategy for monitoring maintenance of the CO NAAQS. The State’s Alternative Monitoring Strategy utilizes ADT vehicle counts collected from permanent automatic traffic recorders in the Billings CO maintenance area to determine average monthly traffic during the traditional high CO concentration season of November through February. The State will compare the latest rolling 3-years of monthly ADT volumes to the 2008–2010 baseline ADT volumes (see Table 1) that correlate to the low CO monitored values during that period (see Table 2). Because mobile sources are the biggest driver of CO pollution, the Montana Department of Environmental Quality (MDEQ) reasoned that any significant increase in CO emissions would have to be accompanied by a significant 4 In addition to Billings and Great Falls, the Missoula, MT CO maintenance area was included in the July 13, 2011Alternative Monitoring Strategy. 5 See Table 2 below. Design values were derived from the EPA AirData (http://www.epa.gov/airdata/) Web site. PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 increase in ADT.6 EPA agrees with the State’s reasoning.

If the CO design value in that season has not increased from the baseline mean by an equal or greater rate at which ADT has increased, and the monitor values remain at or below 50% of the CO NAAQS (2nd max concentration ≤ 4.5 ppm), the monitor may again be removed and the ADT counts will continue to be relied upon to determine compliance with the NAAQS. This process will be repeated each time the rolling 3-year ADT increases by a factor of 25% (e.g. 50%, 75%) above the baseline 2008–2010 period, and the same analysis will be conducted to determine if the monitors can again be removed. 6 See ‘‘Review of National Ambient Air Quality Standards for Carbon Monoxide,’’ 76 FR 54294, August 31, 2011. 7 Design values were derived from the EPA AirData (http://www.epa.gov/airdata/) Web site. E:\FR\FM\02DEP1.SGM 02DEP1 71372 Federal Register / Vol. 79, No. 231 / Tuesday, December 2, 2014 / Proposed Rules 40 CFR 58.14(c) allows approval of requests to discontinue ambient monitors ‘‘on a case-by-case basis if discontinuance does not compromise data collection needed for implementation of a NAAQS and if the requirements of appendix D to 40 CFR part 58, if any, continue to be met.’’ EPA finds that the Alternative Monitoring Strategy meets the criteria of 40 CFR 58.14(c) for the Billings CO maintenance area. Given the long history of low CO concentrations in the Billings area, and the adequacy of the Alternative Monitoring Strategy at ensuring continued attainment of the CO NAAQS, EPA finds it appropriate to approve the State’s request to discontinue the Billings monitor and use the Alternative Monitoring Strategy in its place. IV. EPA’s Evaluation of the Billings Second 10-Year CO Maintenance Plan The following are the key elements of a LMP for CO: Emission Inventory, Maintenance Demonstration, Monitoring Network/Verification of Continued Attainment, Contingency Plan, and Conformity Determinations. Below, we describe our evaluation of each of these elements as it pertains to the revised Billings Maintenance Plan. mstockstill on DSK4VPTVN1PROD with PROPOSALS A. Emission Inventory The revised Billings Maintenance Plan contains an emissions inventory for the base year 2009. The emission inventory is a list, by source, of the air contaminants directly emitted into the Billings CO maintenance area on a typical winter day in 2009.8 The mobile sources data in the emission inventory in the July 13, 2011 submittal were developed using emissions modeling methods that EPA did not consider upto-date. After consultation with EPA, the State then provided EPA with technical information to clarify and supplement the emissions inventory from the July 13, 2011 submittal.9 This supplemental technical information utilized EPA recommended mobile sources emissions modeling methods (MOVES2010b) .10 The Billings LMP and supplementary technical information contain detailed emission inventory information that was prepared 8 Violations of the CO NAAQS are most likely to occur on winter weekdays. 9 The supplemental technical information was sent to EPA on July 23, 2014, and is available in the docket for this action. 10 Motor Vehicle Emissions Simulator (MOVES) model; version 2010b. VerDate Sep<11>2014 16:20 Dec 01, 2014 Jkt 235001 in accordance with EPA guidance and is acceptable to EPA.11 B. Maintenance Demonstration We consider the maintenance demonstration requirement to be satisfied for areas that qualify for and use the LMP option. As mentioned above, a maintenance area is qualified to use the LMP option if that area’s maximum 8-hour CO design value for eight consecutive quarters does not exceed 7.65 ppm (85% of the CO NAAQS). EPA maintains that if an area begins the maintenance period with a design value no greater than 7.65 ppm, the applicability of prevention of significant deterioration requirements, the control measures already in the SIP, and federal measures should provide adequate assurance of maintenance over the 10-year maintenance period. Therefore, EPA does not require areas using the LMP option to project emissions over the maintenance period. Because CO design values in the Billings area are consistently well below the LMP threshold (See Table 2), the State has adequately demonstrated that the Billings area will maintain the CO NAAQS into the future. C. Monitoring Network/Verification of Continued Attainment In the revised Billings Maintenance Plan, the State commits to ‘‘continue to monitor CO using an instrumental method or a functionally equivalent monitoring methodology as approved by EPA.’’ As noted, EPA is proposing to approve the State’s Alternative Monitoring Strategy for the Billings CO maintenance area as part of this action. Based on final approval of the Alternative Monitoring Strategy, we will have concluded that the strategy is adequate to verify continued attainment of the CO NAAQS in Billings. D. Contingency Plan Section 175A(d) of the CAA requires that a maintenance plan include contingency provisions to promptly correct any violation of the NAAQS that occurs after redesignation of an area. To meet this requirement, the State has identified appropriate contingency measures along with a schedule for the development and implementation of such measures. The Billings Maintenance Plan stated in section 56.12.7.4 that the State will use an exceedance of the CO NAAQS as the trigger for adopting specific contingency measures for the Billings 11 ‘‘Procedures for Processing Requests to Redesignate Areas to Attainment,’’ from John Calcagni, September 4, 1992. PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 area. As noted, the Alternative Monitoring Strategy requires reinstitution of a CO monitor in Billings if traffic levels increase from the 2008– 2010 baseline by a factor of 25%. Therefore, EPA finds that CO emissions in Billings are very unlikely to increase to the point of an exceedance without that exceedance being observed by a gaseous monitor. The State indicates that notification of an exceedance to EPA and other affected governments will occur within 60 days. Upon notification of a CO NAAQS exceedance, MDEQ and Riverstone Health will convene to recommend an appropriate contingency measure or measures that would be necessary to avoid a violation of the CO NAAQS. The necessary contingency measure(s) will then be proposed for local adoption. Finalization of the necessary contingency measures for local adoption will be completed within three months of the exceedance notification. Full implementation of the locally adopted contingency measure(s) will be achieved within one year after the recording of a CO NAAQS violation. The potential contingency measures, identified in section 56.12.7.4.C of the Billings Maintenance Plan, include implementation of a mandatory oxygenated fuels program with local regulations in the Billings or Yellowstone County area for the winter months of November, December, and January, and establishing an episodic woodburning curtailment program. A more complete description of the triggering mechanism and these contingency measures can be found in section 56.12.7.4 of the Billings Maintenance Plan. We find that the contingency measures provided in the State’s maintenance plan for Billings are sufficient and meet the requirements of section 175A(d) of the CAA. E. Transportation Conformity Transportation conformity is required by section 176(c) of the CAA. Conformity to a SIP means that transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA’s conformity rule at 40 CFR part 93, subpart A requires that transportation plans, programs and projects conform to SIPs and establish the criteria and procedures for determining whether or not they conform. To effectuate its purpose, the conformity rule requires a demonstration that emissions from the Regional Transportation Plan (RTP) and the Transportation Improvement E:\FR\FM\02DEP1.SGM 02DEP1 mstockstill on DSK4VPTVN1PROD with PROPOSALS Federal Register / Vol. 79, No. 231 / Tuesday, December 2, 2014 / Proposed Rules Program (TIP) are consistent with the motor vehicle emission budget (MVEB) contained in the control strategy SIP revision or maintenance plan (40 CFR 93.101, 93.118, and 93.124). A MVEB is defined as the level of mobile source emissions of a pollutant relied upon in the attainment or maintenance demonstration to attain or maintain compliance with the NAAQS in the nonattainment or maintenance area.12 Under the LMP policy, emissions budgets are treated as essentially not constraining for the length of the maintenance period. While EPA’s LMP guidance does not exempt an area from the need to affirm conformity, it explains that the area may demonstrate conformity without submitting a MVEB. This is because it is unreasonable to expect that an LMP area will experience so much growth in that period that a violation of the CO NAAQS would result.13 Therefore, for the Billings CO maintenance area, all actions that require conformity determinations for CO under our conformity rule provisions are considered to have already satisfied the regional emissions analysis and ‘‘budget test’’ requirements in 40 CFR 93.118. Since LMP areas are still maintenance areas, certain aspects of transportation conformity determinations still will be required for transportation plans, programs and projects. Specifically, for such determinations, RTPs, TIPs and projects must still demonstrate that they are fiscally constrained (40 CFR 93.108) and meet the criteria for consultation and Transportation Control Measure implementation in the conformity rule provisions (40 CFR 93.112 and 40 CFR 93.113, respectively). In addition, projects in LMP areas still will be required to meet the applicable criteria for CO hot spot analyses to satisfy ‘‘project level’’ conformity determinations (40 CFR 93.116 and 40 CFR 93.123), which must also incorporate the latest planning assumptions and models available (40 CFR 93.110 and 40 CFR 93.111, respectively). In view of the CO LMP policy, the effect of this proposed approval will be to affirm our adequacy finding such that no regional emissions analyses for future transportation CO conformity determinations are required for the CO LMP period and beyond (as per EPA’s CO LMP policy and 40 CFR 93.109(e)). 12 Further information concerning EPA’s interpretations regarding MVEBs can be found in the preamble to EPA’s November 24, 1993, transportation conformity rule (see 58 FR 62193— 62196). 13 Limited Maintenance Plan Guidance at 4. October 6, 1995. VerDate Sep<11>2014 16:20 Dec 01, 2014 Jkt 235001 V. Proposed Action EPA is proposing to approve the revised Billings Maintenance Plan submitted on July 13, 2011. This maintenance plan meets the applicable CAA requirements and EPA has determined it is sufficient to provide for maintenance of the CO NAAQS over the course of the second 10-year maintenance period out to 2022. EPA is also proposing to approve the State’s Alternative Monitoring Strategy for the Billings CO maintenance area. We do not propose to approve application of the Alternative Monitoring Strategy in other areas of Montana with this action, as the Alternative Monitoring Strategy must be considered on a case-by-case basis specific to the circumstances of each particular CO maintenance area rather than broadly. VI. Statutory and Executive Orders Review Under the CAA, 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 CAA. Accordingly, this action merely proposes to approve 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 (Public Law 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); PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 71373 • 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.

A. Billings CO Maintenance Plan
Under the Clean Air Act (CAA) Amendments of 1990, the Billings area
was designated as nonattainment and classified as a ``not classified''
CO area. This was because the area had been designated as nonattainment
before November 15, 1990, but had not violated the CO NAAQS in 1988 and
1989 (56 FR 56694, November 6, 1991). On February 9, 2001, the Governor
of Montana submitted to us a request to redesignate the Billings CO
nonattainment area to attainment for the CO NAAQS. Along with this
request, the Governor submitted a CAA section 175A(a) maintenance plan
which demonstrated that the area would maintain the CO NAAQS for the
first 10 years following our approval of the redesignation request. We
approved the State's redesignation request and 10-year maintenance plan
on February 21, 2002 (67 FR 7966).
[[Page 71371]]
Eight years after an area is redesignated to attainment, CAA
section 175A(b) requires the state to submit a subsequent maintenance
plan to EPA, covering a second 10-year period.\1\ This second 10-year
maintenance plan must demonstrate continued compliance with the NAAQS
during this second 10-year period. To fulfill this requirement of the
CAA, the Governor of Montana's designee submitted the second 10-year
update of the Billings CO maintenance plan (hereafter; ``revised
Billings Maintenance Plan'') to us on July 13, 2011. With this action,
we are proposing approval of the revised Billings Maintenance Plan.
\1\ In this case, the initial maintenance period extended
through 2012. Thus, the second 10-year period extends through 2022.
The 8-hour CO NAAQS--9.0 parts per million (ppm)--is attained when
such value is not exceeded more than once a year. 40 CFR 50.8(a)(1).
The Billings area has attained the 8-hour CO NAAQS from 1988 to the
present. In October 1995, EPA issued guidance that provided
nonclassifiable CO nonattainment areas the option of using a less
rigorous ``limited maintenance plan'' (LMP) option to demonstrate
continued attainment and maintenance of the CO NAAQS.\2\ According to
this guidance, areas that can demonstrate design values (2nd highest
max) at or below 7.65 ppm (85% of exceedance levels of the 8-hour CO
NAAQS) for eight consecutive quarters qualify to use an LMP. The area
qualified for and used EPA's LMP option for the first 10-year Billings
CO maintenance plan (67 FR 7966, February 21, 2002). For the revised
Billings Maintenance Plan the State again used the LMP option to
demonstrate continued maintenance of the CO NAAQS in the Billings area.
We have determined that the Billings area continues to qualify for the
LMP option because the maximum design value for the most recent eight
consecutive quarters with certified data at the time the State adopted
the plan (years 2008 and 2009) was 2 ppm.\3\
\2\ Memorandum ``Limited Maintenance Plan Option for
Nonclassifiable CO Nonattainment Areas'' from Joseph W. Paisie,
Group Leader, EPA Integrated Policy and Strategies Group, to Air
Branch Chiefs, October 6, 1995.
\3\ See Table 2 below. Additionally, according to the LMP
guidance, an area using the LMP option must continue to have a
design value ``at or below 7.65 ppm until the time of final EPA
action on the redesignation.'' Table 2, below, demonstrates that the
area meets this requirement.
B. Alternative CO Monitoring Strategy
Along with the revised Billings Maintenance Plan, the State
submitted a CO maintenance plan for the Great Falls, Montana
maintenance area, and an alternative strategy for monitoring continued
attainment of the CO NAAQS in all of the State's CO maintenance areas
on July 13, 2011.\4\ The State submitted the alternative monitoring
strategy to conserve resources by discontinuing the gaseous CO ambient
monitors in both the Billings and Great Falls CO maintenance areas. In
place of the gaseous ambient monitors, the State's alternative method
relies on rolling 3-year Average Daily Traffic (ADT) vehicle counts
collected from permanent automatic traffic recorders in each
maintenance area. We commented on the State's ``Alternative Monitoring
Strategy,'' and the State submitted to us a revised version of the
strategy which incorporated our comments on June 22, 2012. The State's
June 22, 2012 Alternative Monitoring Strategy replaced the version
submitted on July 13, 2011.
\4\ In addition to Billings and Great Falls, the Missoula, MT CO
maintenance area was included in the July 13, 2011Alternative
III. EPA's Evaluation of Montana's Alternative Monitoring Strategy in
Since 2002, no Billings CO monitor has registered a design value
greater than 4.4 ppm, which is roughly half of the NAAQS. Further,
since 2006, no Billings monitor has registered a design value greater
than 2.2 ppm, roughly 25% of the NAAQS.\5\ Citing these consistently
low monitor values, and expressing a desire to conserve monitoring
resources, the State has requested to discontinue CO monitoring in
Billings and instead use an alternative strategy for monitoring
maintenance of the CO NAAQS.
\5\ See Table 2 below. Design values were derived from the EPA
AirData (http://www.epa.gov/airdata/) Web site.
The State's Alternative Monitoring Strategy utilizes ADT vehicle
counts collected from permanent automatic traffic recorders in the
Billings CO maintenance area to determine average monthly traffic
during the traditional high CO concentration season of November through
February. The State will compare the latest rolling 3-years of monthly
ADT volumes to the 2008-2010 baseline ADT volumes (see Table 1) that
correlate to the low CO monitored values during that period (see Table
2). Because mobile sources are the biggest driver of CO pollution, the
Montana Department of Environmental Quality (MDEQ) reasoned that any
significant increase in CO emissions would have to be accompanied by a
significant increase in ADT.\6\ EPA agrees with the State's reasoning.

Carbon Monoxide,'' 76 FR 54294, August 31, 2011.

If the rolling 3-year ADT value is 25% higher than the average
value from the 2008-2010 baseline period of 34,246, the State will
reestablish CO ambient monitoring in Billings the following high season
(November-February). If the CO design value in that season has not
increased from the baseline mean by an equal or greater rate at which
ADT has increased, and the monitor values remain at or below 50% of the
CO NAAQS (2nd max concentration <= 4.5 ppm), the monitor may again be
removed and the ADT counts will continue to be relied upon to determine
compliance with the NAAQS. This process will be repeated each time the
rolling 3-year ADT increases by a factor of 25% (e.g. 50%, 75%) above
the baseline 2008-2010 period, and the same analysis will be conducted
to determine if the monitors can again be removed.
\7\ Design values were derived from the EPA AirData (http://www.epa.gov/airdata/) Web site.
[[Page 71372]]
40 CFR 58.14(c) allows approval of requests to discontinue ambient
monitors ``on a case-by-case basis if discontinuance does not
compromise data collection needed for implementation of a NAAQS and if
the requirements of appendix D to 40 CFR part 58, if any, continue to
be met.'' EPA finds that the Alternative Monitoring Strategy meets the
criteria of 40 CFR 58.14(c) for the Billings CO maintenance area. Given
the long history of low CO concentrations in the Billings area, and the
adequacy of the Alternative Monitoring Strategy at ensuring continued
attainment of the CO NAAQS, EPA finds it appropriate to approve the
State's request to discontinue the Billings monitor and use the
Alternative Monitoring Strategy in its place.
IV. EPA's Evaluation of the Billings Second 10-Year CO Maintenance Plan
The following are the key elements of a LMP for CO: Emission
Inventory, Maintenance Demonstration, Monitoring Network/Verification
of Continued Attainment, Contingency Plan, and Conformity
Determinations. Below, we describe our evaluation of each of these
elements as it pertains to the revised Billings Maintenance Plan.
The revised Billings Maintenance Plan contains an emissions
inventory for the base year 2009. The emission inventory is a list, by
source, of the air contaminants directly emitted into the Billings CO
maintenance area on a typical winter day in 2009.\8\ The mobile sources
data in the emission inventory in the July 13, 2011 submittal were
developed using emissions modeling methods that EPA did not consider
up-to-date. After consultation with EPA, the State then provided EPA
with technical information to clarify and supplement the emissions
inventory from the July 13, 2011 submittal.\9\ This supplemental
technical information utilized EPA recommended mobile sources emissions
modeling methods (MOVES2010b) .\10\ The Billings LMP and supplementary
technical information contain detailed emission inventory information
that was prepared in accordance with EPA guidance and is acceptable to
EPA.\11\
\8\ Violations of the CO NAAQS are most likely to occur on
winter weekdays.
\9\ The supplemental technical information was sent to EPA on
July 23, 2014, and is available in the docket for this action.
\10\ Motor Vehicle Emissions Simulator (MOVES) model; version
\11\ ``Procedures for Processing Requests to Redesignate Areas
to Attainment,'' from John Calcagni, September 4, 1992.
We consider the maintenance demonstration requirement to be
satisfied for areas that qualify for and use the LMP option. As
mentioned above, a maintenance area is qualified to use the LMP option
if that area's maximum 8-hour CO design value for eight consecutive
quarters does not exceed 7.65 ppm (85% of the CO NAAQS). EPA maintains
that if an area begins the maintenance period with a design value no
greater than 7.65 ppm, the applicability of prevention of significant
deterioration requirements, the control measures already in the SIP,
and federal measures should provide adequate assurance of maintenance
over the 10-year maintenance period. Therefore, EPA does not require
areas using the LMP option to project emissions over the maintenance
period. Because CO design values in the Billings area are consistently
well below the LMP threshold (See Table 2), the State has adequately
demonstrated that the Billings area will maintain the CO NAAQS into the
In the revised Billings Maintenance Plan, the State commits to
``continue to monitor CO using an instrumental method or a functionally
equivalent monitoring methodology as approved by EPA.'' As noted, EPA
is proposing to approve the State's Alternative Monitoring Strategy for
the Billings CO maintenance area as part of this action. Based on final
approval of the Alternative Monitoring Strategy, we will have concluded
that the strategy is adequate to verify continued attainment of the CO
NAAQS in Billings.
Section 175A(d) of the CAA requires that a maintenance plan include
contingency provisions to promptly correct any violation of the NAAQS
that occurs after redesignation of an area. To meet this requirement,
the State has identified appropriate contingency measures along with a
schedule for the development and implementation of such measures.
The Billings Maintenance Plan stated in section 56.12.7.4 that the
State will use an exceedance of the CO NAAQS as the trigger for
adopting specific contingency measures for the Billings area. As noted,
the Alternative Monitoring Strategy requires reinstitution of a CO
monitor in Billings if traffic levels increase from the 2008-2010
baseline by a factor of 25%. Therefore, EPA finds that CO emissions in
Billings are very unlikely to increase to the point of an exceedance
without that exceedance being observed by a gaseous monitor.
The State indicates that notification of an exceedance to EPA and
other affected governments will occur within 60 days. Upon notification
of a CO NAAQS exceedance, MDEQ and Riverstone Health will convene to
recommend an appropriate contingency measure or measures that would be
necessary to avoid a violation of the CO NAAQS. The necessary
contingency measure(s) will then be proposed for local adoption.
Finalization of the necessary contingency measures for local adoption
will be completed within three months of the exceedance notification.
Full implementation of the locally adopted contingency measure(s) will
be achieved within one year after the recording of a CO NAAQS
The potential contingency measures, identified in section
56.12.7.4.C of the Billings Maintenance Plan, include implementation of
a mandatory oxygenated fuels program with local regulations in the
Billings or Yellowstone County area for the winter months of November,
December, and January, and establishing an episodic woodburning
curtailment program. A more complete description of the triggering
mechanism and these contingency measures can be found in section
56.12.7.4 of the Billings Maintenance Plan.
We find that the contingency measures provided in the State's
maintenance plan for Billings are sufficient and meet the requirements
of section 175A(d) of the CAA.
Transportation conformity is required by section 176(c) of the CAA.
Conformity to a SIP means that transportation activities will not
produce new air quality violations, worsen existing violations, or
delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA's
conformity rule at 40 CFR part 93, subpart A requires that
transportation plans, programs and projects conform to SIPs and
establish the criteria and procedures for determining whether or not
they conform. To effectuate its purpose, the conformity rule requires a
demonstration that emissions from the Regional Transportation Plan
(RTP) and the Transportation Improvement
[[Page 71373]]
Program (TIP) are consistent with the motor vehicle emission budget
(MVEB) contained in the control strategy SIP revision or maintenance
plan (40 CFR 93.101, 93.118, and 93.124). A MVEB is defined as the
level of mobile source emissions of a pollutant relied upon in the
attainment or maintenance demonstration to attain or maintain
compliance with the NAAQS in the nonattainment or maintenance area.\12\
\12\ Further information concerning EPA's interpretations
regarding MVEBs can be found in the preamble to EPA's November 24,
1993, transportation conformity rule (see 58 FR 62193--62196).
Under the LMP policy, emissions budgets are treated as essentially
not constraining for the length of the maintenance period. While EPA's
LMP guidance does not exempt an area from the need to affirm
conformity, it explains that the area may demonstrate conformity
without submitting a MVEB. This is because it is unreasonable to expect
that an LMP area will experience so much growth in that period that a
violation of the CO NAAQS would result.\13\ Therefore, for the Billings
CO maintenance area, all actions that require conformity determinations
for CO under our conformity rule provisions are considered to have
already satisfied the regional emissions analysis and ``budget test''
requirements in 40 CFR 93.118.
\13\ Limited Maintenance Plan Guidance at 4. October 6, 1995.
Since LMP areas are still maintenance areas, certain aspects of
transportation conformity determinations still will be required for
transportation plans, programs and projects. Specifically, for such
determinations, RTPs, TIPs and projects must still demonstrate that
they are fiscally constrained (40 CFR 93.108) and meet the criteria for
consultation and Transportation Control Measure implementation in the
conformity rule provisions (40 CFR 93.112 and 40 CFR 93.113,
respectively). In addition, projects in LMP areas still will be
required to meet the applicable criteria for CO hot spot analyses to
satisfy ``project level'' conformity determinations (40 CFR 93.116 and
40 CFR 93.123), which must also incorporate the latest planning
assumptions and models available (40 CFR 93.110 and 40 CFR 93.111,
In view of the CO LMP policy, the effect of this proposed approval
will be to affirm our adequacy finding such that no regional emissions
analyses for future transportation CO conformity determinations are
required for the CO LMP period and beyond (as per EPA's CO LMP policy
and 40 CFR 93.109(e)).
EPA is proposing to approve the revised Billings Maintenance Plan
submitted on July 13, 2011. This maintenance plan meets the applicable
CAA requirements and EPA has determined it is sufficient to provide for
maintenance of the CO NAAQS over the course of the second 10-year
maintenance period out to 2022.
EPA is also proposing to approve the State's Alternative Monitoring
Strategy for the Billings CO maintenance area. We do not propose to
approve application of the Alternative Monitoring Strategy in other
areas of Montana with this action, as the Alternative Monitoring
Strategy must be considered on a case-by-case basis specific to the
circumstances of each particular CO maintenance area rather than
