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). The air quality planning requirements for moderate PM10 nonattainment areas are set out in subparts 1 and 4, part D, Title I of the Act. As described in section 110 and 172 of the Act, areas designated nonattainment based on failure to meet the PM10 NAAQS are required to develop SIPs with sufficient control measures to expeditiously attain and maintain the NAAQS. On July 8, 1994, the EPA approved the PM10 SIP for Salt Lake and Utah Counties (59 FR 35036). The SIP included a demonstration of attainment and various control measures, including emission limits at stationary sources. Because emissions of SO2 and NOX contribute significantly to the PM10 problem in the area, the SIP included limits on emissions of SO2 and NOX in addition to emissions of PM10 . On September 26, 1995, the EPA designated Ogden City as nonattainment for PM10 and classified the area as moderate under section 107(d)(3) of the Act (60 FR 38726; July 28, 1995). Subsequently, the EPA approved a clean data determination for the Ogden City nonattainment area on January 7, 2013 (78 FR 885), suspending obligations to submit certain requirements of part D, subparts 1 and 4 of the Act for so long as the area continues to attain. On July 3, 2002 Utah submitted SIP revisions adopting rule R307- 110-10, which incorporated revisions to portions of Utah's SIP Section IX, Part A, and rule R307-110-17, which incorporated revisions to portions of Utah's SIP Section IX Part H. These revisions were approved by the EPA on December 23, 2002 (67 FR 78181). The revisions to Utah's SIP Section IX Part H removed several stationary sources subject to reasonably available control technology (RACT) requirements from the initial list of RACT sources in the Utah County nonattainment area, based on SIP threshold limits for PM10 , NOx, and SO2 of 100 tpy, 200 tpy, and 250 tpy, respectively. In doing so, the number of major stationary sources included in the SIP for the Utah County nonattainment area was reduced from 14 sources to 5 sources. Notably, one of the sources retained in Utah's 2002 SIP was Geneva Steel, which underwent a protracted closure and had largely ceased operations by 2004. In 2005, the PacifiCorp--Lake Side Power Plant was constructed on a portion of the former Geneva Steel facility, utilizing banked emission credits from Geneva Steel's closure. 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. III. EPA's Evaluation of Utah's SIP A. R307-110-17 1. Section R307-110-17 incorporates the amendments to Section IX.H into state rules, thereby making them effective as a matter of state law. This is a ministerial provision and does not by itself include any control measures. B. Subsection IX.H.1-4 1. Subsection IX.H.1. General Requirements: Control Measures for Area and Point Sources, Emission Limits and Operating Practices, PM10 Requirements. This section establishes general requirements for record keeping, [[Page 32289]] reporting, and monitoring for the stationary sources subject to emissions limits under subsections IX.H.2-4. Additionally, this section establishes general refinery requirements, addressing limitations on emitting units common to the refineries in the nonattainment areas. These general refinery requirements include limits at fluid catalytic cracking units, limits on refinery fuel gas, restrictions on liquid fuel oil consumption, requirement for sulfur removal units, and requirements for hydrocarbon flares. 2. Subsection IX.H.2. Source Specific Emission Limitations in Salt Lake County PM10 Nonattainment/Maintenance Area. This section establishes specific emission limitations for 14 sources. These sources are Big West Oil Refinery; Bountiful City Light and Power; Central Valley Reclamation Facility; Chevron Products Company; Hexcel Corporation; Holly Refining and Marketing Company; Kennecott Utah Copper (KUC): Bingham Canyon Mine; KUC: Copperton Concentrator; KUC: Power Plant and Tailings Impoundment; KUC: Smelter and Refinery; PacifiCorp Energy: Gadsby Power Plant; Tesoro Refining & Marketing Company; University of Utah; and West Valley Power Holdings, LLC. Major stationary sources were identified based on their potential to emit (PTE) of 100 tons per year (tpy) or more of PM10 , NOx, or SO2 . A summary of the current emission limits, for retained sources, is outlined in Table 1 below, and a summary of the proposed new emission limits is outlined in Table 2 below.

Subsection IX.H.3. Source Specific Emission Limitations in Utah County PM10 Nonattainment/Maintenance Area. This section establishes specific emission limitations for 6 sources. These sources are Brigham Young University (BYU); Geneva Nitrogen Inc.; PacifiCorp Energy: Lake Side Power Plant; Payson City Corporation: Payson City Power; Provo City Power: Power Plant; and Springville City Corporation: Whitehead Power Plant. Major stationary sources were identified based on their PTE of 100 tons per year (tpy) or more for PM10 , NOX , and SO2 . It is important to note that the SIP threshold of 100 tpy for all three pollutants is less than the previous SIP major stationary source thresholds Utah established in its 2002 SIP revision. The 2002 SIP revision had established major stationary source thresholds for PM10 , NOX , and SO2 at 100 tpy, 200 tpy, and 250 tpy, respectively. By lowering the SIP threshold to 100 tpy for all three pollutants, three sources are now added into the SIP. These sources are BYU, Payson City Power and PacifiCorp Energy--Lake Side Power Plant. PacifiCorp Energy-- Lake Side Power Plant sits on a portion of the former Geneva Steel site. A summary of the current emission limits, for retained sources, is outlined in Table 3 below, and a summary of the proposed new emission limits are outlined in Table 4 below.

This will be accomplished through the installation of low NOX burners with Flue Gas Recirculation. \7\ The NOX limit for Units #4 and #6 is 127 ppm (38.5 lb/hr) until December 31, 2018, at which time the limit will then be 36 ppm (19.2 lb/hr). 4. Subsection IX.H.4. Interim Emission Limits and Operating Practices. R307-110-17 Section IX, Control Measures for Area and Point Sources, Part H, Emission Limits. 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. A summary of the proposed interim emission limits is outlined in Table 5 below.

Consideration of Section 110(l) of the CAA Under section 110(l) of the CAA, the EPA cannot approve a SIP revision if the revision would interfere with any applicable requirements concerning attainment and reasonable further progress (RFP) toward attainment of the NAAQS, or any other applicable requirement of the Act. In addition, section 110(l) requires that each revision to an implementation plan submitted by a state shall be adopted by the state after reasonable notice and public hearing. The Utah SIP revisions that the EPA is proposing to approve do not interfere with any applicable requirements of the Act. The DAR section R307-110-17 and Subsection IX.H.1-4, submitted January 4, 2016, and January 19, 2017 are intended to strengthen the SIP. Therefore, CAA section 110(l) requirements are satisfied. Specifically, the proposed emission limits for the retained sources in the Salt Lake County nonattainment area will result in a reduction of PM10 , SO2 , and NOX emissions by 10.64 tpd, 12.87 tpd and 29.97 tpd, respectively, when compared to the limits established in the original PM10 SIP. Given the large net decrease in emissions from the retained major stationary sources in the Salt Lake County nonattainment area, the proposed action will enhance the area's ability to attain or maintain the NAAQS. The proposed emissions from Geneva Nitrogen, Provo City Power Plant, and the Springville City Corporation--Whitehead Power Plant are consistent with the 2002 SIP revisions for Utah County. Additionally, this proposed action adds three sources--BYU, Payson City Power and PacifiCorp Energy--Lake Side Power Plant. Both BYU and Payson City Power have been in existence since the original 1994 SIP, and BYU was initially included as a source in the original 1994 SIP, but was removed in 2002. The inclusion of these two sources do not reflect an increase in emissions into the Utah County nonattainment area airshed, but rather reflect a change in the approach of how stationary sources are included into the SIP. PacifiCorp Energy--Lake Side Power Plant is also being added into the SIP, but its addition does not reflect an emissions increase to the nonattainment area because the facility was required to use offsetting emissions, largely made available through the closure of the Geneva Steel facility. The closing of Geneva Steel resulted in the removal of approximately 1,700 tpy PM10 , 1,400 tpy SO2 , and 4,200 tpy NOX from the Utah County airshed. These emission reductions were banked and made available for purchase for future major source construction and modifications. In order to construct the Lakeside Power Plant, banked emission credits were purchased and used at an offset ratio of 1.2:1 (e.g. For every 1.0 tpy of emissions allowed at the Lakeside Power Plant, 1.2 tpy of banked emission credits must be spent from the Utah emissions credit offset registry.). In total the Lakeside Power Plant utilized banked emission credits for PM10, SO2 , and NOX in the amounts of 257 tpy, 66 tpy, and 337 tpy, respectively. Given the offset ratio required for the construction of the Lakeside Power Plant, the inclusion of this source into the SIP does not result in any emissions increase to the Utah County airshed, and actually reflects a net decrease from the 2002 SIP. As a result of the decreased emissions from the closure of the Geneva Steel facility, and the offsetting ratio required to construct the Lake Side Power Plant, the proposed revision to the Utah County PM10 SIP will enhance the area's ability to attain or maintain the NAAQS. V. Summary of Proposed Action and Request for Public Comment The EPA is proposing approval and requesting public comment on revisions to Administrative Rule R307-110-17 and revisions to Subsection IX.H.1-4 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 proposed revisions reflect more stringent emission levels for total emissions of PM10 , SO2 , and NOX for each of the affected facilities, as well as updates 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. VI. Incorporation by Reference In this rule, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference the DAQ PM10 SIP revisions as discussed in section III of this preamble. 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). VII. Statutory and Executive Order Reviews Under the CAA, 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); 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, this action merely proposes to approve state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:Is 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); 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 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). [[Page 32294]] In addition, the SIP is not approved to 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 proposed 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).
