[EPA-R08-OAR-2018-0235; FRL-9993-66-Region 8]

Approval and Promulgation of Air Quality Implementation Plans; 
State of Montana; Missoula PM10 Nonattainment Area Limited Maintenance 
Plan and Redesignation Request

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving the 
Limited Maintenance Plan (LMP), submitted by the State of Montana to 
the EPA on August 3, 2016, for the Missoula moderate particulate matter 
with an aerodynamic diameter less than or equal to a nominal 10 
micrometers (PM10) nonattainment area (Missoula NAA) and 
concurrently redesignating the Missoula NAA to attainment of the 24-
hour PM10 National Ambient Air Quality Standard (NAAQS). In 
order to approve the LMP and redesignation, the EPA is determining that 
the Missoula NAA has attained the 1987 24-hour PM10 NAAQS of 
150 [micro]g/m\3\. This determination is based upon monitored air 
quality data for the PM10 NAAQS during the years 2015-2017. 
The EPA is also approving the Missoula LMP as meeting the appropriate 
transportation conformity requirements. Lastly, the EPA is approving 
certain rule revisions the Missoula City-County Air Pollution Control 
Program submitted on August 3, 2016, and August 22, 2018.

DATES: Effective June 24, 2019.

SUPPLEMENTARY INFORMATION: Throughout this document ``we,'' ``us,'' and 
``our'' means the EPA.

I. Background

    The Missoula NAA encompasses the City of Missoula and was 
designated nonattainment for the 1987 24-hour PM10 NAAQS and 
classified as moderate under section 107(d)(4)(B), following enactment 
of the Clean Air Act (CAA) Amendments of 1990. See 56 FR 56694 
(November 6, 1991). On August 30, 1995, the EPA fully approved the 
Missoula NAA PM10 plan including reasonably available 
control measures (RACM), an attainment demonstration, emissions 
inventory, quantitative milestones, and control and contingency 
requirements.
    The factual and legal background for this action is discussed in 
detail in our March 5, 2019 (84 FR 7846) proposed approval of certain 
rule revisions to the Missoula City-County Air Pollution Control 
Program, the Missoula Limited Maintenance Plan, the Missoula LMP as 
meeting the appropriate transportation conformity requirements, and 
concurrent redesignation of the Missoula NAA to attainment of the NAAQS 
for PM10.

II. Response to Comments

    The public comment period on the EPA's proposed rule opened on 
March 5, 2019, the date of its publicaction in the Federal Register, 
(84 FR 7846), and closed on April 4, 2019. During this time, the EPA 
received no comments.

III. Final Action

    The EPA is making the determination that the Missoula NAA has 
attained the 1987 24-hour PM10 NAAQS of 150 [micro]g/m\3\. 
This determination is based upon monitored air quality data for the 
PM10 NAAQS during the years 2015-2017. Additionally, the EPA 
is approving the Missoula NAA LMP submitted on August 3, 2016, as 
meeting the applicable CAA requirements, and we have determined the LMP 
to be sufficient to provide for maintenance of the PM10 
NAAQS over the course of the 10-year maintenance period out to 2029. 
The EPA is also approving the Missoula LMP as meeting the appropriate 
transportation conformity requirements found in 40 CFR 93, subpart A. 
The EPA is approving most of the revisions submitted on August 3, 2016 
and August 22, 2018 (Chapter 4 revisions). Specifically, the EPA is 
approving revisions to the eight chapters on Definitions, Failure to 
Attain Standards, Emergency Episode Avoidance Plan, Industrial Sources, 
Fugitive Particulate, Solid Fuel Burning Devices, Administrative 
Procedures, and Penalties. As identified in Section IV of the March 5, 
2019 proposed approval, the EPA is not acting on Chapter 9, rule 9.204 
in the August 3, 2016 submittal or the IBR revisions in the August 22, 
2018 submittal. Lastly, this rule redesignates the Missoula NAA from 
nonattainment to attainment of the PM10 NAAQS. A list of the 
revisions to the Missoula City-County Air Pollution Control Program 
that the EPA is approving is outlined in Table 1 below.

IV. Incorporation by Reference

    In this document, the EPA is finalizing regulatory text that 
includes incorporation by reference. In accordance with requirements of 
1 CFR 51.5, the EPA is finalizing the incorporation by reference of the 
Regulations described in the amendments to 40 CFR part 52 set forth 
below. The EPA has made, and will continue to make, these materials 
generally available through www.regulations.gov and at the EPA Region 8 
Office (please contact the person identified in the FOR FURTHER 
INFORMATION CONTACT section of this preamble for more information). 
Therefore, these materials have been approved by the EPA for inclusion 
in the State implementation plan (SIP), have been incorporated by 
reference by the EPA into that plan, are fully federally enforceable 
under sections 110 and 113 of the CAA as of the effective

[[Page 24038]]

date of the final rulemaking of the EPA's approval, and will be 
incorporated by reference in the next update to the SIP compilation.

V. Statutory and Executive Orders Review

    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, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this 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 action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866;
     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, 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 CAA; and
     Does not provide the 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, the SIP is not approved to apply on any Indian 
reservation land or in any other area where the EPA or an Indian tribe 
has demonstrated that a tribe has jurisdiction. In those areas of 
Indian country, the rule does not have tribal implications and will not 
impose substantial direct costs on tribal governments or preempt tribal 
law as specified by Executive Order 13175 (65 FR 67249, November 9, 
2000).
    The Congressional Review Act, 5 U.S.C. 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. The EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by July 23, 2019. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action 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).)
