I. Summary of Proposed Rule

    On October 12, 2016 (81 FR 70382), the EPA proposed to determine 
that the Eastern San Luis Obispo ozone NAA has attained the 2008 ozone 
standard by the applicable attainment date of July 20, 2106, based on 
complete, quality-assured and certified ambient air quality monitoring 
data for the 2013-2015 monitoring period. San Luis Obispo County is the 
northern-most county within the air basin designated by California as 
the South Central Coast Air Basin. The NAA encompasses roughly the 
eastern half of San Luis Obispo County. For the precise boundaries of 
the Eastern San Luis Obispo 2008 ozone NAA, see 40 CFR 81.305.
    Our proposed rule provided background information on the 2008 ozone 
standards,\1\ the EPA's classification of the Eastern San Luis Obispo 
NAA under the Clean Air Act (CAA) as ``Marginal'' for the 2008 ozone 
standard, and the EPA's prior approval of an extension of the 
applicable attainment date for the area from July 20, 2015 to July 20, 
2016 (81 FR 26697, May 4, 2016). In our proposed rule, we described our 
obligation under CAA section 181(b)(2)(A) to determine whether an ozone 
NAA attained the ozone NAAQS by the applicable attainment date within 
six months of that date; how we determine whether an area's air quality 
meets the 2008 ozone standard; and the relevant air quality monitoring 
agencies in the Eastern San Luis Obispo ozone NAA, their monitoring 
network plans, and the relevant ozone monitoring sites. We also 
discussed our previous review of the networks and network plans, the 
annual certifications of ambient air monitoring data, and our 
determination of completeness for 2013-2015 data from the two ozone 
monitoring sites within the Eastern San Luis Obispo NAA.
---------------------------------------------------------------------------

    \1\ Since the primary and secondary 2008 ozone standards are the 
same, we hereafter refer to them herein using the singular ``2008 
ozone standard.''
---------------------------------------------------------------------------

    Our proposed rule included a table of ozone ``design values'' at 
the two ozone monitoring sites in the Eastern San Luis

[[Page 93621]]

Obispo NAA.\2\ See 81 FR 70382, at 70384. As explained in our proposed 
rule, the 2008 ozone standard is attained in an area when the design 
value is less than or equal to 0.075 parts per million (ppm), as 
determined in accordance with 40 CFR part 50, appendix P, at each 
monitoring site within the area. See 40 CFR 50.15. Based on our review 
of the monitoring data, which showed a design value for the area of 
0.073 ppm (based on data collected at the Red Hills site) for 2013-
2015, and taking into account the extent and reliability of the 
applicable ozone monitoring network, we proposed to determine that the 
Eastern San Luis Obispo NAA has attained the 2008 ozone standard by the 
applicable attainment date of July 20, 2016 based on complete, 
certified and quality-assured data for the 2013-2015 period. Lastly, we 
noted that if we finalize our proposed determination, then the Marginal 
Eastern San Luis Obispo NAA would not be subject to reclassification to 
``Moderate'' for the 2008 ozone standard, that a determination of 
attainment by the applicable attainment date would not constitute a 
redesignation, and that the designation status of the Eastern San Luis 
Obispo area would remain nonattainment for the 2008 ozone standard 
until such time as the EPA determines that the area meets the CAA 
requirements for redesignation to attainment. Please see our proposed 
rule for more information concerning these topics.
---------------------------------------------------------------------------

    \2\ The design value is a statistic that describes the air 
quality 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 concentrations. 
The design value for a given area is based on the monitoring site 
with the highest design value.
---------------------------------------------------------------------------

II. Public Comments and EPA Responses

    The EPA's proposed action provided a 30-day public comment period. 
During this period, we received no comments.

III. Final Action

    Under CAA section 181(b)(2)(A), and based on the rationale 
presented in our proposed rule and summarized above, the EPA is 
finalizing our determination that the Eastern San Luis Obispo ozone NAA 
has attained the 2008 ozone NAAQS by the applicable attainment date of 
July 20, 2016. The EPA is making this determination based on complete, 
quality-assured and certified ambient air quality monitoring data for 
the 2013-2015 monitoring period. As a result of this determination, the 
Eastern San Luis Obispo 2008 ozone NAA will not be reclassified to a 
higher classification for the 2008 ozone standard.

IV. Statutory and Executive Order Reviews

    This action is a determination based on air quality data 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);
     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 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, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because 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 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 February 21, 2017. 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)).

    (i) Determination of attainment. The EPA has determined that, as of 
January 20, 2017, the San Luis Obispo (Eastern San Luis Obispo) 2008 8-
hour ozone nonattainment area in California has attained the 2008 ozone 
standard by the July 20, 2016 applicable attainment date, based upon 
complete, quality-

assured and certified data for 2013-2015. Therefore, the EPA has met 
its obligation pursuant to CAA section 181(b)(2)(A) to determine, based 
on the area's air quality data as of the attainment date, whether the 
area attained the standard. As a result of this determination, the San 
Luis Obispo (Eastern San Luis Obispo) 2008 ozone nonattainment area in 
California will not be reclassified for failure to attain by the July 
20, 2016 applicable attainment date under section 181(b)(2)(A).
