I. Summary of EPA’s Proposed Action
On July 30, 2015, EPA proposed to approv e the Mammoth Lakes PM10 redesignation request and maintenance plan
. We propos ed th is action because California’s SIP revision meets the C lean
A ir A ct (CAA) requirements and EPA guidance concerning redesignations to attainment of a National Ambient Air Quality Standard (NAAQS or standard ) and maintenance plans (80 FR 45477)
. For our detailed procedural and substantive review of the State’s SIP submittal and o u r discussion of our findings and rationale for our proposal and this final action, please see our
p roposal and the docket for this action.
First, under CAA section 107(d)(3)(D), EPA p ropos ed to
approve the State ’s request to redesignate the Mammoth Lak es PM10 nonattainment area to attainment for the PM10 NAAQS. In our July 30, 2015 proposal , we concluded th at the area has met the five criteria for redesignation under CAA section 107(d)(3)(E): (1) the area has attained the PM10 NAAQS over the period 20 09

- 2014; (2) the required portions of the SIP are fully approvedThis document is a prepubl ication version signed by Regional Administrator Jared Blumenfeld on Septembe r 18 ,

4 for the area; (3) the improvement in ambient air quality in the area is due to permanent and enforceable reductions in PM10 emissions; (4) California has met all requirements applicable to th e Mammoth Lakes PM10 nonattainment area with respect to section 110 and part D of the CAA; and, (5) the Mammoth Lakes PM10 Maintenance Plan, as described below , meets the requirements of CAA section 175A
. Second, under section 110(k)(3) of the CAA , EPA pro posed to approve as a revision to the SIP, the maintenance plan developed by the Great Basin Unified Air Pollution Control District (GBUAPCD) entitled “2014 Update Air Quality Maintenance Plan and Redesignation Request for the Town of Mammoth Lakes” ( herei n and in our proposal referred to as the Mammoth Lakes PM10 Maintenance Plan), dated May 5, 2014, submitted by California, through the California Air Resources Board (CARB), to EPA on October 21, 2014. 1 EPA proposed to find that the Mammoth Lakes PM10 Main tenance Plan meets the requirements in section 175A of the CAA. The plan’s maintenance demonstration shows that the Mammoth Lakes area will continue to attain the PM10 NAAQS for at least 10 years beyond redesignation (i.e. through 2030 ) by continued implem entation of the local control measures approved

5 into the SIP. The plan’s contingency provisions incorporate a process for identifying new or more stringent control measures in the event of a future monitored violation. Finally, EPA
p roposed to approve the plan’s 2012 emission inventor y as meeting the requirements of CAA section 172 and 175A.
Third, EPA proposed to approve the motor vehicle emission budget s ( budgets ) in the Mammoth Lakes PM10 Maintenance Plan because we find they meet the applicable transpor tation conformity requirements under 40 CFR 93.118(e). With our proposal published July 30, 2015, EPA informed the public that

we are reviewing the plan’s budgets for adequacy and that we started the public comment period on adequacy of the proposed budget s . This comment period closed on August 31, 2015. We received no public comments concerning the adequacy of the proposed PM10 motor vehicle emissions budgets. II. Public Comments and EPA Responses EPA’s proposed rule provided a 30

- day comment period.
Dur ing this comment period we received no comments on our proposal

6 California , air quality monitoring data, and other relevant materials contained within our docket , EPA f ind s that the State has addressed all the necessary requirements for redesignation of the Mammoth Lakes nonattainment area to attainment of the PM10 NAAQS, pursuant to CAA sections 107(d)(3)(E) and 175A
. First, under CAA section 107(d)(3)(D), we are approv ing the
State 's request, which accompanied the submittal of the Mammoth Lakes PM10 Main tenance P lan, to redesignate the Mammoth Lakes PM10 nonattainment area to attainment for the 24

- hour PM10 NAAQS. Ou r redesignation of the Mammoth Lakes area is based on

our determination that the area has met the five criteria for redesignation under CAA section 107(d)(3)(E): (1) the area has attained the 24

- hour PM10 NAAQS as demonstrated by 2009

- 2014 data ; 2 (2) the r elevant portions of the SIP are fully approved; (3) the improvement in air quality in the Mammoth Lakes area is due to permanent and enforceable reductions in PM10 emissions; (4) California has met all requirements applicable to the Mammoth Lakes PM10 nona ttainment area with respect to section 110 and part D of the CAA; and, (5) our approval of the Mammoth Lakes PM10 Maintenance Plan, as part of this action.

2 We reviewed 2015 preliminary data received from the State and found that the Mammoth Lakes area did not show exceedances of the 24

- hour PM10 NAAQS in the first quarter of 2015. Second quarter data was not submitted by the State in time for consideration w ithin this notice.This document is a prepubl ication version signed by Regional Administrator Jared Blumenfeld on Septembe r 18 ,

201 5 . We have taken steps to ensure the accuracy of this version, but it is not the official version.

7 Second, under section 110(k)(3) of the CAA , EPA is
approv ing the Mammoth Lakes PM10 Maintenance Plan and finds that it meets the requirements of Section 175A. We find that the maintenance demonstration show s that the area will continue to attain the 24

- hour PM10 NAAQS for at least 10 years beyond redesignation (i.e ., through 2030). We find that the Maintenance Plan provides a contingency process for identifying and adopting new or more stringent control measures if a monitored violation of the PM10 NAAQS occurs. Finally, w e are approv ing the 2012 emissions inventory as meeting applicable requirements for emissions inventories in Section s 172 and 175A of the CAA
. Last, w e find that the Mammoth Lakes PM10 M aintenance
P lan’s motor vehicle emissions budgets meet applicable CAA requirements for maintenance plans and trans portation conformity requirements under 40 CFR 93.118(e). With the effective date of this action, these approved budgets must be used in any future regional PM10 regional emissions analysis conducted by the State and the Federal Highway Administration.

IV. Statut ory and Executive Order Reviews 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);This document is a prepubl ication version signed by Regional Administrator Jared Blumenfeld on Septembe r 18 ,

201 5 . We have taken steps to ensure the accuracy of this version, but it is not the official version.

8 40 CFR 52.02(a). Thus, in rev iewing 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 201 1);

• 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 a s specified in Executive Order 13132 (64 FR 43255, August 10, 1999);This document is a prepubl ication version signed by Regional Administrator Jared Blumenfeld on Septembe r 18 ,

201 5 . We have taken steps to ensure the accuracy of this version, but it is not the official version.

9 • 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 a ction 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 i nconsistent 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, the S tate plan that EPA is approv ing today does not apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas o f Indian country, th is rule , as it relates to the maintenance plan, 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, 2 000).This document is a prepubl ication version signed by Regional Administrator Jared Blumenfeld on Septembe r 18 ,

10 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 action and other required information to the U.S. Senate, the U.S. House of Representatives, an d 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. 8 04(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 [INSERT DATE 60 DAYS AFTER THE DATE OF PUBLICATION IN THE Federal Regis ter ] . 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 ruleThis document is a prepubl ication version signed by Regional Administrator Jared Blumenfeld on Septembe r 18 ,
