## I. Background

                    EPA is taking final action to approve (with one exception) the revisions to Title 17, Chapter 8, subchapter 8 of the Administrative Rules of Montana (ARM) submitted by the State on June 4, 2013, that relate to the State's PSD program. The revisions to the State PSD SIP were adopted by the Montana Department of                           ( print page 4794)                        Environmental Quality (MDEQ) on September 27, 2012, and became effective October 12, 2012.                

                    Montana's revisions addressed certain requirements in EPA's November 29, 2005 “Final Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standards—Phase 2,” 70 FR 71612 (“Phase 2 Ozone Implementation Rule”). EPA's November 29, 2005 rule required states to revise their programs for major source permitting to address ozone formation by properly regulating precursor pollutants. “Precursor pollutants” are pollutants that combine to form another pollutant; in particular, nitrogen oxides (NOX) react with volatile organic compounds to form ozone. In the Phase 2 Ozone Implementation Rule, EPA identified NOX                     as an ozone precursor pollutant in attainment and unclassifiable areas. Accordingly, the Phase 2 Ozone Implementation Rule amended the definitions in 40 CFR 51.166 of “major stationary source,” “major modification,” “significant,” and “regulated NSR pollutant” to include NOX                     as an ozone precursor; the rule also amended certain requirements regarding monitoring of ozone to reflect the identification of NOX                     as an ozone precursor.                

                    However, prior to Montana's June 4, 2013 submittal, the State had not amended its PSD rules accordingly. As a result, in a July 22, 2011 final rule (Approval and Disapproval and Promulgation of State Implementation Plan Revisions; Infrastructure Requirements for the 1997 8-Hour Ozone National Ambient Air Quality Standards; Montana), EPA partially disapproved a Montana SIP submission that (among other things) addressed PSD requirements pursuant to CAA section 110(a)(2)(C), because Montana's PSD rules did not properly address NOX                     as an ozone precursor pollutant as required by the Phase 2 Ozone Implementation Rule. 76 FR 43918; see also 76 FR 28934 (proposal). Under CAA section 110(c)(1)(B), this disapproval started a two-year Federal Implementation Plan (FIP) clock as to this deficiency, which required EPA to promulgate a FIP within two years of the disapproval unless the State submitted and we approved a plan revision correcting the deficiency. As we are now taking final action to approve Montana's June 4, 2013, submittal, which addresses the requirements of the Phase 2 Ozone Implementation Rule, this action fixes the deficiency identified in our prior disapproval and removes our FIP obligations.                

## II. What are the changes that EPA is taking final action to approve?

With respect to Montana's June 4, 2013 submittal, EPA is taking final action to approve revisions to the Montana SIP that bring the State PSD program into conformance with the requirements of the Phase 2 Ozone Implementation Rule.

                    In our September 29, 2014 proposed action (79 FR 58311), we proposed to approve the following revisions to the Administrative Rules of Montana (ARM):                     *17.8.801(20)(a) (major modification); 17.8.801(22)(b) (major stationary source); 17.8.801(25) (nitrogen oxides or NO**X**); 17.8.801(27)(a) (significant); and 17.8.818(7)(a)(6) (Review of Major Source and Major Modifications—Source Applicability and Exemptions).*                     The submittal also corrected a small error in an August 15, 2012 Montana submittal regarding the treatment of fine particulate matter (PM2.5). We have not acted on the remaining portions of the August 15, 2012 submittal; EPA will act on the correction in the June 4, 2013 submittal in tandem with our future action on the rest of the August 15, 2012 submittal.                

We provided a detailed explanation of the basis of approval in our proposed rulemaking (see 79 FR 58311). We invited comment on all aspects of our proposal and provided a 30-day comment period. The comment period ended on October 29, 2014.

## III. Response to Comments

We received one comment during the public comment period. This one comment was in support of our proposed rule, and we acknowledge receipt of that comment.

## IV. What action is EPA taking today?

As discussed in our proposed rulemaking, the requirements included in Montana's PSD program, as specified in ARM 17.8.801 and ARM 17.8.818, are substantially the same as the federal provisions for PSD as set forth at 40 CFR 51.166. Thus, for the reasons discussed in our proposal notice and summarized above, EPA is taking final action to approve the revisions to the ARM 17.8.801 and 17.8.818 as outlined in Section II of this rulemaking (with the small exception noted there) and as submitted to EPA by the State of Montana on June 4, 2013.

## 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, 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 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 in 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.

                    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                           ( print page 4795)                        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 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 March 30, 2015. 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 CAA section 307(b)(2).)
