ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R07-OAR-2017-0251; FRL 9967-49-Region 7]


Approval of Missouri Air Quality Implementation Plans; Final 
Rule; Determination of Attainment for the 2010 1-Hour Primary Sulfur 
Dioxide National Ambient Air Quality Standard; Jefferson County 
Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to determine that the Jefferson County nonattainment area, in 
Missouri, has attained the 2010 1-hour primary Sulfur Dioxide 
(SO2) National Ambient Air Quality Standard (NAAQS) per the 
EPA's Clean Data Policy. This determination of attainment is based upon 
complete, quality assured, and certified ambient air monitoring data 
from the 2014-2016 monitoring period, associated dispersion modeling, 
and supplemental emissions inventory information, which demonstrate 
that the Jefferson County area attained the 2010 1-hour primary 
SO2 NAAQS.

DATES: This final rule is effective on October 13, 2017.

ADDRESSES: EPA has established a docket for this action under Docket ID 
No. EPA-R07-OAR-2017-0251. All documents in the docket are listed on

I. Background Information

    On June 2, 2010 (75 FR 35520), the EPA established a health-based 
1-hour primary SO2 NAAQS at 75 ppb. Upon promulgation of a 
new or revised NAAQS, section 107(d) of the Clean Air Act (CAA) 
requires the EPA to designate any area that does not meet (or that 
contributes to ambient air quality in a nearby area that does not meet) 
the NAAQS as nonattainment. On August 5, 2013, the EPA designated a 
portion of Jefferson County, Missouri, as nonattainment for the 2010 1-
hour primary SO2 NAAQS, effective October 4, 2013.\1\ The 
designation was based on 2008-2010 monitoring data in Herculaneum, 
Missouri, which monitored violations of the standard (see section III 
of this document for additional monitoring information). The effective 
date of the nonattainment designation was October 4, 2013. This action 
established an attainment date five years after the effective date for 
the areas designated as nonattainment for the 2010 SO2 NAAQS 
(i.e., by October 4, 2018).
---------------------------------------------------------------------------

    \1\ 78 FR 47191 (August 5, 2013), codified at 40 CFR 81.326.
---------------------------------------------------------------------------

    On February 2, 2016, the state submitted a request asking the EPA 
to determine that the nonattainment area attained the 2010 1-hour 
primary SO2 NAAQS per the EPA's Clean Data 
Policy.2 3 On June 23, 2017, the EPA published a notice of 
proposed rulemaking (NPR) which proposed to approve the State's 
requests. See 82 FR 28605. Specifically, the EPA proposed to take the 
following actions: (1) Determine that the Jefferson County 
SO2 nonattainment area is attaining the 2010 1-hour 
SO2 NAAQS; (2) determine that the Jefferson County 
SO2 nonattainment area has clean monitoring data; (3) 
suspend the requirements for the state to submit an attainment 
demonstration, a reasonable further progress plan, contingency 
measures, and other planning SIPs revisions related to attainment of 
the 2010 1-hour primary SO2 NAAQS until such time, if any, 
that the EPA subsequently determines, after notice-and-comment 
rulemaking in the Federal Register, that the area has violated the 2010 
1-hour primary SO2 NAAQS.

    The details of Missouri's submittal and the rationale for EPA's 
proposed action are explained in the NPR and will not be restated here.

II. EPA's Response to Comments

    The public comment period on EPA's proposed rule opened June 23, 
2017, the date of its publication in the Federal Register, and closed 
on July 24, 2017. During this period, the EPA received one set of 
public comments on the NPR, which supported the proposed redesignation 
and provided additional technical information. The EPA acknowledges 
these supportive comments, and the additional technical information, 
however, as the comments were essentially in favor of the agency's 
proposed action, the EPA is not responding to the individual comments.

III. What action is EPA taking?

    The EPA is finalizing its determination that the Jefferson County 
2010 1-hour primary SO2 nonattainment area (hereby referred 
to as ``the nonattainment area''), in Missouri, has attained the 2010 
1-hour primary SO2 NAAQS.\4\ This action is based on 
complete, quality assured, and certified ambient air monitoring data 
from the 2013-2015 monitoring period, with additional certified 
monitoring data from 2016, associated dispersion modeling for the 2013-
2015 emission years, as well as supplemental 2016 emissions inventory 
information--which show that the nonattainment area has attained the 
2010 1-hour primary SO2 NAAQS. 5 6
---------------------------------------------------------------------------

    \4\ In accordance with appendix T to 40 CFR part 50, the 1-hour 
primary SO2 NAAQS is met at an ambient air quality 
monitoring site when the valid 1-hour primary standard design value 
is less than or equal to 75 parts per billion (ppb). See 40 CFR 
50.17(b).
    \5\ In accordance with appendix T to 40 CFR part 50, a 1-hour 
primary SO2 NAAQS design value is valid if it encompasses 
three consecutive calendar years of complete data. A year meets data 
completeness requirements when all 4 quarters are complete. A 
quarter is complete when at least 75 percent of the sampling days 
for each quarter have complete data. A sampling day has complete 
data if 75 percent of the hourly concentration values, including 
state-flagged data affected by exceptional events which have been 
approved for exclusion by the Administrator, are reported.
    \6\ Monitoring data must be reported, quality assured, and 
certified in accordance with the requirements set forth in 40 CFR 
part 58.
---------------------------------------------------------------------------

    The EPA has made the monitoring data, the modeling data, the 
supplemental emissions inventory information and additional information 
submitted by the state to support this action available in the docket 
to this rulemaking through www.regulations.gov and/or at the EPA Region 
7 Office (please contact the person identified in the For Further 
Information Contact section of this preamble for more information).

IV. Statutory and Executive Order Reviews

A. General Requirements

    Under the CAA, a determination that a nonattainment area is 
attaining a NAAQS is an action that affects the status of a 
geographical area and does not impose any additional regulatory 
requirements on sources beyond those imposed by state law. A 
determination of attainment does not in and of itself create any new 
requirements, but rather results in the applicability of requirements 
contained in the CAA for areas that have been stated above. Moreover, 
the Administrator is required to approve a SIP submission that complies 
with the provisions of the CAA and applicable Federal regulations. See 
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 CAA. Accordingly, these actions merely approve state 
law as meeting federal requirements and do not impose additional 
requirements beyond those imposed by state law. This action results in 
the suspension of certain Federal requirements and would not impose any 
additional requirements. For these reasons, 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);

[[Page 42947]]

     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 (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, this action does not 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).

B. Congressional Review Act

    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. 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).

C. Petitions for Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by July 11, 2016. 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).
