[EPA-R08-OAR-2017-0298; FRL-9969-01-Region 8]


Approval and Promulgation; State of Utah; Salt Lake County and 
Utah County Nonattainment Area Coarse Particulate Matter State 
Implementation Plan Revisions To Control Measures for Point Sources

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is finalizing 
approval of certain State Implementation Plan (SIP) revisions submitted 
by Utah on January 4, 2016, and of certain revisions submitted on 
January 19, 2017, for the coarse particulate matter (PM10) 
national ambient air quality standard (NAAQS) in the Salt Lake County 
and Utah County PM10 nonattainment areas. The revisions that 
the EPA is approving are located in Utah Division of Administrative 
Rule (DAR) R307-110-17 and SIP Subsection IX.H.1-4, and establish 
emissions limits for PM10, NOX and SO2 
for certain stationary sources in the nonattainment areas. These 
actions are being taken under section 110 of the Clean Air Act (CAA).

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

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R08-OAR-2017-0298. All documents in the docket are 
listed on the http://www.regulations.gov Web site. Although listed in

SUPPLEMENTARY INFORMATION: 

I. Background

    Under the 1990 amendments to the CAA, Salt Lake and Utah Counties 
were designated nonattainment for PM10 and classified as 
moderate areas by operation of law as of November 15, 1990 (56 FR 
56694, 56840; November 6, 1991). On July 8, 1994, the EPA approved the 
PM10 SIP for the Salt Lake and Utah County Nonattainment 
Areas

[[Page 47150]]

(59 FR 35036). The SIP included a demonstration of attainment and 
various control measures, including emission limits at stationary 
sources.
    On January 4, 2016, Utah submitted SIP revisions to R307-110-17 
titled ``Section IX, Control Measures for Area and Point Sources, Part 
H, Emission Limits'' and revisions to Subsection IX.H.1-4. The titles 
for Subsection IX.H.1-4 include: (1) General Requirements: Control 
Measures for Area and Point Sources, Emission Limits and Operating 
Practices, PM10 Requirements; (2) Source Specific Emission 
Limitations in Salt Lake County PM10 Nonattainment/
Maintenance Area; (3) Source Specific Emission Limitations in Utah 
County PM10 Nonattainment/Maintenance Area; and (4) Interim 
Emission Limits and Operating Practices. Additionally, on January 19, 
2017, Utah submitted revisions to Subsection IX.H.1-4. Further 
discussion of the revisions to R307-110-17 and Subsection IX.H.1-4 can 
be found below.
    On July 13, 2017 (82 FR 32287), the EPA proposed to approve certain 
SIP revisions to the Salt Lake County and Utah County NAA Moderate area 
SIPs submitted by the State. Our proposed notice provides details on 
the EPA's evaluation of the State's submittals. The submittals dated 
January 4, 2016, and January 19, 2017, contained revisions to the Utah 
DAR, Title R307--Environmental Quality, set of rules, and SIP 
subsection IX.H.1-4.

II. Response to Comments

    The EPA did not receive any comments on the July 13, 2017 proposed 
action.

III. Final Action

    For the reasons stated in our proposed notice, the EPA is 
finalizing approval of revisions to Administrative Rule R307-110-17 and 
revisions to Subsection IX.H.1-4 for incorporation into the Utah SIP as 
submitted by the State of Utah on January 4, 2016, and January 19, 
2017. These revisions establish emissions limitations and related 
requirements for certain stationary sources of PM10, 
NOX and SO2, and will therefore serve to continue 
progress towards attainment and maintenance of the PM10 
NAAQS in the nonattainment areas. The revisions reflect more stringent 
emission levels for total emissions of PM10, SO2, 
and NOX for each of the affected facilities, as well as 
updates of the inventory of major stationary sources to accurately 
reflect the current sources in both the Salt Lake County and Utah 
County nonattainment areas (e.g., removing sources which no longer 
exist, or are now covered under an area source rule). The updated list 
of sources and revised emission limits for the major stationary sources 
in the two nonattainment areas will serve to enhance both area's 
ability to attain or maintain the NAAQS.
    The specific emission limits and operating practices the EPA is 
finalizing for approval are listed in the following tables:

\4\ This section establishes interim emission limits for sources whose new emission limits under Subsections IX.H.2 and 3 are based on controls that are
  not currently installed, with the provision that all necessary controls needed to meet the emission limits under Subsection IX.H.2 and IX.H.3 shall be
  installed by January 1, 2019.

IV. Incorporation by Reference

    In this rule, the EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, the EPA is finalizing the incorporation by reference of Utah 
Division of Administrative Rules described in the amendments set forth 
to 40 CFR part 52 below. The EPA has made, and will continue to make, 
these materials generally available through www.regulations.gov and/or 
at the EPA Region 8 Office (please contact the person identified in the 
FOR FURTHER INFORMATION CONTACT section of this preamble for more 
information).
    Therefore, these materials have been approved by the EPA for 
inclusion in the SIP, have been incorporated by reference by the EPA 
into that plan, are fully federally enforceable under sections 110 and 
113 of the CAA as of the effective date of the final rulemaking of the 
EPA's approval, and will be incorporated by reference by the Director 
of the Federal Register in the next update to the SIP compilation.\1\
---------------------------------------------------------------------------

    \1\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

V. Statutory and Executive Order Reviews

A. General Requirements

    Under the CAA, 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, the 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. 
For this reason, these actions:
     Are not significant regulatory actions 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); Do 
not impose an information collection burden under the provisions of the 
Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Are 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.);
     Do 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);
     Do not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Are not economically significant regulatory actions based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Are not significant regulatory actions subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Are 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
     Do 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, the SIP 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 
final 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. 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).

C. Petitions for Judicial Review

    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this

[[Page 47153]]

action must be filed in the United States Court of Appeals for the 
appropriate circuit by December 11, 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 CAA section 307(b)(2).
