I. What is the B ackground for th is A ction?
A. Ozone NAAQS , Area Designations and Classifications The Clean Air Act (CAA or “ Act ” ) requires the EPA to establish national primary and secondary standards for cer tain widespread pollutants, such as ozone, that cause or contribute to air pollution that is reasonably anticipated to endanger public health or welfare. 1 In the 1970s, the EPA promulgated primary and secondary ozone standards, based on a 1

- hour average . I n

1 See sections 108 and 109 of the Clean Air Act (CAA or “Act”) . Primary standards represent ambient air quality standards the attainment and maintenance of which the Environmental Protection Agency ( EPA ) has determined, including a margin of safety, are requisite to protect the public health. Secondary standards repr esent ambient air quality standards the attainment and maintenance of which the EPA has determined are requisite to protect the public welfare from any known or anticipated adverse effects associated with the presence of such air pollutant in the ambient a ir. CAA section 109(b).4 This document is a prepublication version signed by EPA Acting Regional Administrator Deborah Jordan on Decem ber 2 , 2016

1997, we replaced the 1

- hour ozone standards with primary and secondary 8

- hour ozone standards. In 2008, we tightened the 8

- hour ozone standards to the level of 0.075 parts per million (ppm), daily maximum 8

- hour average. 2 See 73 FR 16436 ( March 27, 2008 ); 40 CFR 50.15

. Since the primary and secondary ozone standards are the same, we refer to them here after in this document using the singular “2008 ozone standard” ( or simply “standard” ) or NAAQS. The 2008 ozone standard is met at an ambient air quality mo nitoring site when the 3

- year average of the annual fourth

- highest daily maximum 8

- hour average ozone concentration is less than or equal to 0.075 ppm , as determined in accordance with 40 CFR part 50 , A ppendix P

. The EPA designated NAAs for the 2008 ozone standard on May 21, 2012, effective July 20, 2012 (77 FR 30088). In that action, the EPA classified (by operation of law) the Mariposa County, C alifornia 3 NAA as a “Marginal” nonattainment area. The original attainment date for the 2008 ozone standard for this Marginal ozone nonattainment area was as expeditious as practicable but not later than July 20, 2015. See 40 CFR 51.1103. In May 2016, the EPA determined that the Mariposa County NAA failed to attain the 2008 ozone standard by the applicable attainme nt date of July 20, 2015, and reclassified the area to the next higher classification, i.e. , “Moderate.” Our determination was based on complete,

2 In 2015, we tightened the ozone National Ambient Air Quality Standards (NAAQS or “standards”) even further and established 0.070 parts per million ( ppm ) , 8

- hour average, as the new ozone NAAQS. See 80 FR 65292 (October 26, 2015). While the 1979 1

- hour ozone NAAQS and 1997 8

- hour ozone NAAQS have been revoked, the 2008 ozone NAAQS remains in effect. 3 Mariposa County is located in central California and is the southern

- most county within the air basin designated by California as the Mountain Counties Air Basin. The nonattainment area designation for Mariposa County encompasses the entire county.5 This document is a prepublication version signed by EPA Acting Regional Administrator Deborah Jordan on Decem ber 2 , 2016

quality

- assured and certified data for 2012

- 2014. 4 States with Moderate ozone NAA s are required to submit revisions to the applicable SIP that comply with the requirements set forth in subpart 2 of part D of title I of the CAA and in the EPA’s ozone implementation rule for the 2008 ozone NAAQS in 40 CFR part 51, subpart AA. The relevan t SIP requirements include, among other requirements, attainment demonstrations and associated reasonably available control measures (RACM), reasonable further progress (RFP) plans, and contingency measures for failure to attain or make RFP. The applicable attainment date for areas classified as Moderate nonattainment for the 2008 ozone NAAQS is as expeditious as practicable but not later than July 20, 2018. See 40 CFR 51.1103.
B. Relevant Statutory and Regulatory Requirements Under the provisions of EPA’ s ozone implementation rule for the 2008 ozone NAAQS, if the EPA issues a determination that an area is attaining the relevant standard, also known as a Clean Data Determination, the requirements for such area to submit attainment demonstrations and associ ated RACM , RFP plans, contingency measures and other planning SIPs related to attainment of the 2008 ozone NAAQS are suspended until such time as the area is redesignated to attainment for the 2008 ozone NAAQS . However, if the EPA later determines , through notice

and

- comment rulemaking, that the area has again violated the 2008 ozone NAAQS, the area is again required to submit such plans. See 40 CFR 5 1 .1118. While these requirements are

4 81 FR 26697 (May 4, 2016). The 2012

- 2014 design value for the Mariposa County NAA was 0.078 parts per million , which exceeded the 2008 ozo ne NAAQS of 0.075 ppm, daily maximum 8

- hour average. We note that today’s action is based on the 2013

- 2015 design value.6 This document is a prepublication version signed by EPA Acting Regional Administrator Deborah Jordan on Decem ber 2 , 2016

. We have taken steps to ensure the accuracy of this version, but it is not the official version.
suspended, the EPA is not precluded from acting upon these SIP elements at any time if submitted to the EPA for review and approval.
C. Ambient Air Quality Monitoring Data A determination of whether an area’s air quality meets the 2008 ozone NAAQS is generally based upon three consecutive calendar years of complete, quality

- assured data measured at established State and Local Air Monitoring Stations (SLAMS) in the NAA and entered into the EPA Air Quality System (AQS) database. Data from ambient air monitoring sites operated by state or local agencie s in compliance with EPA monitoring requirements must be submitted to AQS. Heads of monitoring agencies annually certify that these data are accurate to the best of their knowledge. Accordingly, the EPA relies primarily on data in AQS when determining the attainment status of an area. See 40 CFR 50.15 ; 40 CFR part 50, Appendix P ; 40 CFR part 53; 40 CFR part 58, A ppendices A, C, D and E. All data are reviewed to determine the

area ’ s air quality status in accordance with 40 CFR part 50, Appendix P

. The 2008 o zone standard is met at an ambient air quality monitoring site when the design value is less than or equal to 0.0 75 ppm , as determined in accordance with 40 CFR part 50, Appendix P

. See 40 CFR 50.1 5

. The design value is a statistic that describes the air q uality status of a given location relative to the level of the NAAQS. For the purpose of comparison with the 2008 ozone standard, the design value for a site is the 3

- year average of the annual fourth

- highest daily maximum 8

- hour average ozone concentratio ns. When the design value is less than or equal to 0.0 75 ppm (based on the rounding convention in 40 CFR part 50, A ppendix P ) at each monitoring site within the area, then the area is meeting the NAAQS. The data completeness7 This document is a prepublication version signed by EPA Acting Regional Administrator Deborah Jordan on Decem ber 2 , 2016

. We have taken steps to ensure the accuracy of this version, but it is not the official version.
requirement is met when the 3

- y ear average percent of days with valid monitoring data is at least 90 percent , and no single year has less than 75 percent data completeness as determined in
accordance with 40 CFR part 50 , A ppendix P

. II. What is the EPA’s A nalysis of the R elevant A ir Q uality D ata?
A. Monitoring Network and Data Considerations The California Air Resources Board ( CARB ) and local a ir p ollution c ontrol d istricts and

a ir q uality m anagement d istricts ( “d istricts ” ) operate ambient air monitoring stations throughout the State of C alifornia . CARB is the lead monitoring agency in the Primary Quality Assurance Organization (PQAO) that includes all the monitoring agencies in the State with a few exceptions. 5 , 6 Within the Mariposa County ozone nonattainment area, there is one ozone SLA MS (referred to as the Jerseydale site ) that is operated by CARB, and one SLAMS (referred to as the Turtleback Dome site in Yosemite National Park) that is operated by the National Park Service (NPS). The ozone monitoring site operated by NPS at Turtleback Dome is one of many sites throughout the U.S. and Canada that comprise the Clean Air Status and Trends Network (CASTNET). 7 Ozone monitors at CASTNET sites meet the EPA’s ambient air quality monitoring requirements of 40 CFR part 58, and data from such sites are submitted to AQS.

5 A Primary Quality Assurance Organization (PQAO) means a monitoring organization, a group of monitoring organizations or other organi zation that is responsible for a set of stations that monitor the same pollutant and for which data quality assessments can be pooled. Each criteria pollutant sampler/monitor at a monitoring station must be associated with only one PQAO. (40 CFR 58.1). 6 The Bay Area Air Quality Management District (AQMD) , the South Coast AQMD and the San Diego Air Pollution Control District are each designated as the PQAO for their respective ambient air monitoring programs. 7 Clean Air Status and Trends Network ( CASTNE T ) is a national monitoring network established to assess trends in pollutant concentrations, atmospheric deposition and ecological effects due to changes in air pollutant emissions. For additional background on CASTNET, see https://www.epa.gov/castnet

Ozone data from CASTNET sites, such as Turtleback Dome, are eligible for use in determining compliance with the ozone NAAQS

. CARB i s the PQAO for the Jerseydale site. The NPS is the PQAO for the Turtleback Dome site

. All state and local air monitoring agencies are required to submit annual monitoring network plans to the EPA. 8 An annual monitoring network plan discusses the status of the air monitoring network, as required und er 40 CFR part 58.10. CARB submits the annual monitoring network plan s for the Jerseydale site

. Since 2007, the EPA has regularly reviewed these annual monitoring network plans for compliance with the ap plicable reporting requirements in 40 CFR part 58. With respect to ozone, the EPA found that the area’s annual monitoring netw ork plans meet the applicable requirements under 40 CFR part 58. See EPA letter s to CARB approving annual monitoring network plans for the years 2013, 2014 and 2015

. 9 The 2016 CASTNET annual network plan, dated June 23, 2016, includes the Turtleback Dome site. 10 The EPA also concluded from its Technical System Audit of the CARB PQAO ( conducted during Summer 2015), that the combined ambient air monitoring network operated

by CARB currently meets or exceeds the requirements for the minimum number of SLAMS for the 2008 ozone standard

. 11 A ll of the monitoring sites in the PQAO are reviewed with respect to monitoring objectives, spatial scales and other site criteria as required by 40 CFR part 58, Appendix D. CARB oversees the qualit y assurance of all data collected within the CARB PQAO. Also, CARB annually certifies that the data it submits to AQS are complete and quality

- assured. This include s data from all CARB sites, including the Jerseydale site. 12 Data from the Turtleback Dome site are certified by the NPS. 13 As noted above, there are two ozone SLAMS monitoring sites operating within the Mariposa County NAA. These sites monitor ozone concen trations on a continuous basis using EPA reference or equivalent methods. 14

, 15 Lastly, consistent with the requirements contained in 40 CFR part 50, the EPA has reviewed the quality

- assured and certified ozone ambient air monitoring data, as recorded in

11 Letter from Elizabeth J. Adams , Acting Director, Air Division, EPA Region IX, to Richard Corey , Executive Officer, CARB, dated August 31, 2016, transmitting findings of the EPA’s 201 5 Technical System Audit of the CARB's ambient air monitoring program. 12 See , e.g., letter from Ravi Ramalingam, Chief, Air Quality Data Branch, CARB , to Elizabeth Adams, Acting Director, Air Division, EPA Region 9, certifying calendar year 2015 ambient air quality data and quality assurance data, May 10, 2016. 13 See , e.g., letter from Barkley Sive , Air Resources Division Program Manager, National Park Service, to Lew Wein s tock, EPA Office of Air Quality Policy and Standards, certifying calendar year 2015 ambient air quality data and quality assurance , dated April 27, 2016. 14 See the CARB’s Annual Monitoring Networ k Report for Twenty

- five Districts in California (July 2015). The EPA approved an ozone season waiver for the Jerseydale site. See letter from Meredith Kurpius, Manager, Air Quality Analysis Office, EPA Region IX, to Ravi Ramalingam , Chief, Consumer Produc ts and Air Quality Assessment Branch, CARB, dated March 8, 2016. The Jerseydale ozone monitor operate s only in the warme r six months of the year. The site is at a high elevation where access during the winter can be problematic. Ozone concentrations during the winter at th e Jerseydale site are well below the levels of the 2008 ozone standard. 15 See the CARB’s Annual Monitoring Network Report for Twenty

- five Districts in California (July 2015)

AQS for the applicable monitoring period, collected at the monitoring sites in the Mariposa County NAA for completeness. The EPA has determined that the data are complete. 16 For the two ozone monitoring sites in Mariposa County , daily maximum 8

- hour average co ncentrations are available for at least 90 percent of the days within the ozone monitoring season, on average for the 2013

- 2015 period, and daily maximum 8

- hour average concentrations are available for at least 75 percent of the days within the ozone monit oring season for each individual year within that period.
B. Evaluation of the Ambient Air Quality Data As noted above, the applicable attainment date for the Mariposa County ozone NAA is July 20, 201 8 ; however, we have reviewed the data collected at the two monitoring sites within that area during the most recent three

- year period (2013

- 2015) to determine whether the area has already attained the 2008 ozone standard. Table 1 s hows the fourth

- highest da ily maximum 8

- hour ozone concentrations for 2013 through 2015 at bot h sites in the Mariposa County ozone NAA and shows the design values for 2013

- 2015. The design value for a given area is based on the monitoring site in the area with the highest design va lue. In this case, the design value for
2013

- 2015 for the Mariposa County ozone NAA is at the Jerseydale site and is 0.07 5 ppm, which is equal to the standard (i.e. , 0.075 ppm ). Therefore, we are determin ing , based on the complete, quality

- assured and cert ified data for 2013

- 2015, that the Mariposa County Moderate ozone NAA has attained the 2008 ozone standard

. We have also reviewed p reliminary data for 2016

. What is the Effect of this Action? With this determination that the Mariposa County ozone NAA has attained the 2008 ozone NAAQS, the obligation on the State of California to submit SIP revisions related to attainment of the 2008 ozone standard in Mariposa County, including but not limited to SIP

rev isions demonstrating attainment and RFP , is suspended until such time as Mari posa County is redesignated to attainment for the 2008 ozone standard , at which time the requirements no longer apply . However, if the EPA determines, through notice

- and

- comment r ulemaking, that Mari pos a

17 See EPA’s Ozone Watch. The November 8, 2016 Ozone Watch reports that the preliminary 2014

County has once again violated the 2008 ozone NAAQS , the n the area is again required to submit the attainment

- related SIP revisions. See 40 CFR 51.1118. This final determination of attainment for the Mariposa County NAA does not c onstitute a redesignation to attainment. Under CAA section 107(d)(3)(E), redesignations to attainment require states to meet a number of additional statutory criteria , including EPA’s approval of a SIP revision demonstrating maintenance of the standard for 10 years after redesignation. The designation status of th e Mariposa Count y area will remain Moderate nonattainment for the 2008 ozone NAAQS until such time as the EPA determines that the area meets the CAA requirements for redesignation to attainment

. IV. Final Action The EPA is taking direct final action to determine that the Mariposa County Moderate ozone NAA has attained the 2008 ozone standard based on complete, quality

- assured and certified ambient air quality monitoring data for the 2013

- 2015 mon itoring period. Preliminary data for 2016 are consistent with continued attainment of the standard in the Mariposa County
NAA. Upon the effective date of this determination , the requirements for the Mariposa County NAA to submit planning SIPs related to at tainment of the standard are suspended until the area is redesignated or the EPA determines that the area has violated the standard, at which time the

area would again be required to submit such plans. We do not think anyone will object to this determination , so we are finalizing it without proposing it in advance. However, in the Proposed Rules section of this Federal Register , we are simultaneously proposing to make the same determination made herein

FEDERAL REGISTER ], we will publish a timely withdrawal in the Federal Register to notify the public that the direct final action will not take effect and we will address the comments in a subsequent final action based on the proposal. If we do not receive timely adverse comments, the direct final action will be effective without further notice on [ INSERT DATE 6 0 DAYS AFTER DATE OF PUBLICATION IN THE FEDERAL REGISTER ]. V. Statutory and Executive Order Reviews
Th is action makes a determination based on air quality data and do es not impose additional requirements beyond those imposed by state law. For that reason, th e action:

• i s 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);

• d o es 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. );

• d o es not contain any unfunded mandate or significantly or uniquely af fect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104

– 4);

• d o es not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);14 This document is a prepublication version signed by EPA Acting Regional Administrator Deborah Jordan on Decem ber 2 , 2016

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

• i s not an economically significant regulatory act ion 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 the 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

• d o es not provide the EPA with the discretionary authority to address, as appropriate, dispr oportionate 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
131 75 (65 FR 67249, November 9, 2000), because the SIP obligations discussed herein do not apply to Indian t ribes, and thus this action will not impose substantial direct costs on tribal governments or preempt tribal law

. 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 eac h 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 6015 This document is a prepublication version signed by EPA Acting Regional Administrator Deborah Jordan on Decem ber 2 , 2016

. We have taken steps to ensure the accuracy of this version, but it is not the official version.
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 C lean 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 DATE OF PUBLICATION IN THE FEDERAL REGISTER ]. 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

. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the Proposed Rules section of today’s Federal Register , rather than file a n immediate petition for judicial review of this direct final rule, so that the EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. T his action may not be challenged later in proceedings to enforce its requirements ( see section 307(b)(2)).
