[EPA-R08-OAR-2012-0352; FRL-9919-97-OAR]


Approval and Promulgation of Air Quality Implementation Plans; 
State of Montana Second 10-Year Carbon Monoxide Maintenance Plan for 
Billings

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing approval of a State Implementation Plan (SIP) 
revision submitted by the State of Montana. On July 13, 2011, the 
Governor of Montana's designee submitted to EPA a second 10-year 
maintenance plan for the Billings area for the carbon monoxide (CO) 
National Ambient Air Quality Standard (NAAQS). This maintenance plan 
addresses maintenance of the CO NAAQS for a second 10-year period 
beyond the original redesignation. EPA is also proposing approval of an 
alternative monitoring strategy for the Billings CO maintenance area, 
which was submitted by the Governor's designee on June 22, 2012.

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 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 
Monitoring Strategy.
---------------------------------------------------------------------------

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.
---------------------------------------------------------------------------

    \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.

    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.

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 
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 
2010b.
    \11\ ``Procedures for Processing Requests to Redesignate Areas 
to Attainment,'' from John Calcagni, September 4, 1992.
---------------------------------------------------------------------------

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 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

[[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, 
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)).

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);
     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.
