Project Description SLCDA has requested the addition of a 450 kW emergency generator, two 1500 kW emergency generators, and three above ground 8,000-gallon storage tanks. In addition to this equipment, SLCDA has requested several equipment items be updated. These updates include adjusting the capacity of an existing generator from 400 kW to 375 kW, the relocation of a 300 kW generator, the removal of a 350 kW generator and a 375 kW generator, and the removal of the burn pit training equipment. EMISSION IMPACT ANALYSIS The SLCDA conducted modeling on 1-hour NO2 emissions for the new emergency generator engines. Detailed results of the modeling can be found in the modeling memo MN104500030-23. The model results for the 1- hour NO2 NAAQS concentration were found to be 96.81% of the standard. The DAQ reviewed and accepted the results of the modeling. The engines passed the standard with the following restrictions: Engineer Review N104500030: Salt Lake City Department of Airports - Salt Lake City International Airport December 29, 2023 Page 3 - Testing may occur between 7am and 7pm for the generators in conditions II.A.34, II.A.35, II.A.36, and II.A.43 - Testing for the above generators shall not exceed 52 tests each per rolling 12-month period. - All other generators may test at any time of the day The source is not required to model for other criteria pollutants and HAPs because the emission increases are below the modeling thresholds per R307-410 or the area is already a nonattainment area for the pollutants.

Engineer Review N104500030: Salt Lake City Department of Airports - Salt Lake City International Airport December 29, 2023 Page 5 Review of BACT for New/Modified Emission Units 1. BACT review regarding new emergency generator engines SLCDA is proposing to install two new emergency backup generators rated 1500 kW each, as well as a 450 kW emergency backup generator. The proposed engines are certified to meet tier 2 emission standards. Emissions from the engine are primarily NOx and CO, with some smaller amounts of other criteria pollutants and HAPs being emitted. The 1500 kW engines will emit 1.46 tons per year of NOx and 0.19 tons per year of CO each. The 450 kW generator will emit 0.29 tons per year of NOx and 0.03 tons per year of CO. To further control emissions, selective catalytic reduction (SCR) and Tier 4 certified engines were evaluated. SCR would control NOx by passing engine exhaust through a stream of urea combined with a solid catalyst to convert the NOx into inert gasses of CO2, water, and nitrogen. This control method is estimated to yield up to 90% control of NOx, however, this number may be significantly lower for emergency engines, as they are only operating for short periods of time less than an hour in length. Because of these operating times, the catalyst chamber may have trouble reaching the temperatures needed for the catalyst to be effective, in the range of 500-1000 degrees Fahrenheit. Additionally, an economic impact analysis was done for SCR technology. Using cost estimates from a 2010 study from the California air resources board (https://ww2.arb.ca.gov/sites/default/files/classic/regact/2010/atcm2010/atcmisor.pdf), the additional capital cost is estimated to be at least $210,000 for the 1500 kW engines, and $37,000 for the 450 kW engine. Using a 10-year life span and a 7% interest rate, a capital recovery factor was determined that annualizes the cost over the lifespan of the equipment. The annualized cost was determined to be $29,904/year each for the 1500 kW engines, $5,284/year for the 450 kW Engine. SCR can control up to 1.3 tons per year each for the 1500 kW engines, giving a cost effectiveness of $23,0003/ton of NOx removed. For the 450 kW engine, it can control up to 0.26 tons per year of NOx, giving a cost effectiveness of $20,323/ton of NOx removed. This is considered economically infeasible, and is not considered further. Tier 4 certified engines were also considered. The emission limits for tier 4 (final) certified engines above 1200 hp are 0.5 g/hp-hr NOx, 0.14 g/hp-hr VOC, and 0.02 g/hp-hr PM. Tier 4 final standards for engines between 600 and 750 hp are 0.3 g/hp-hr NOx, 0.14 g/hp-hr VOC, and 0.01 g/hp-hr PM. For the 1500 kW and 450 kW engines, this represents a 92.5% reduction in NOx emissions. Using the same source from CARB as above, it is estimated an additional capital cost of $310,000 for the 1,500 kW engines would be required. This gives an annualized cost of $44,020/year and a cost effectiveness of $32,545/ton of NOx removed. For the 450 kW engine, this would be a capital cost of $55,000, an annualized cost of $7,831/year, and a cost effectiveness of $29,047/ton of NOx removed. For both engine sizes, this is considered economically infeasible, and is not considered further. The only remaining option is the proposed tier 2 engines, which are accepted as BACT. Additionally, ultra-low sulfur diesel fuel will be used in the engines, defined as fuel with a sulfur content of 15 ppm or less, which reduces formation of SO2 and PM10/PM2.5 emissions. These controls are accepted as BACT. BACT for control of the 450 kW and 1500 kW emergency backup engines will be installation of an engine certified to tier 2 nonroad diesel engine standards, use of ultra-low sulfur diesel fuel, and a 20% opacity limit. [Last updated December 29, 2023] Engineer Review N104500030: Salt Lake City Department of Airports - Salt Lake City International Airport December 29, 2023 Page 6 2. BACT review regarding Storage Tanks SLCDA is proposing to install three 8,000 gallon ASTs, containing diesel and gasoline. This installation will increase emissions of VOCs and HAPs from working and breathing losses in the tanks. Due to the relatively low emissions from the tanks, totaling 1.30 tons per year of VOCs combined, add-on controls such as a vapor capture system would not be economically feasible to implement. SLCDA evaluated and proposed the following emission reduction methods for controlling VOCs: Use of a white enamel coating to reduce thermal absorption Submerged filling, pumping fuel in under the surface of existing liquid to reduce turbulence when filling which reduces VOCs Best management practices including regular inspections of the tanks and pipes for leaks and other maintenance issues, and use of fuel stabilizers when fuel is stored for long durations. The DAQ accepts the above measures as BACT for the diesel and gasoline storage tanks.

Comment regarding emission calculations: Emissions from the new and removed emergency generators were calculated as follows: 100 hours of operation annually are assumed, using emission factors from manufacturer specification sheets. The NOx emission factor was determined to be 95% of the NOx + NMHC emission factor, the SO2 and CO2 emission factors were determined from AP-42 Section 3.4, Table 3.4-1, assuming fuel with 15 ppm sulfur content. PM10 and PM2.5 emission factors were assumed to be equivalent to the total PM emission factor. HAP emission factors were determined from AP-42 Section 3.3 and 3.4, Tables 3.3-2, 3.4-3 and 3.4-4. Storage Tank emissions were determined according to methodology presented in AP-42 Section 7.1 for horizontal fixed-roof tanks. For the gasoline storage tank, gasoline was modeled as motor gasoline RVP 13. [Last updated October 17, 2023] 2. Comment regarding NSPS and MACT: NSPS NSPS Subpart Dc applies to owners and operators of small industrial-commercial-institutional steam generating boilers. The source has existing boilers rated at 25 MMBtu/hr; therefore, these boilers are subject to this subpart. NSPS Subpart IIII applies to owners and operators of stationary CI ICE that commence construction after July 11, 2005, where the stationary CI ICE are manufactured after April 1, 2006. Many on-site emergency generator engines are subject to this subpart. The equipment list in section II.A details which engines are subject to this subpart. MACT MACT Subpart ZZZZ applies to owners and operators of stationary RICE at a major or area source of HAP emissions. Many on-site emergency generator engines are subject to the standard. Please see II.A for which engines are subject to this subpart. MACT Subpart CCCCCC applies to each gasoline dispensing facility that is located at an area source. The gasoline storage tanks are subject to the requirements of this subpart. MACT Subpart JJJJJJ applies to industrial, commercial, or institutional boilers located at area sources of HAPs. However, section 63.11195 states that gas-fired boilers are exempt from the requirements of this subpart. This exemption also allows up to 48 hours of operation with fuel oil for testing purposes, which is enforced in condition II.B.1.d. Therefore, this facility is not subject to this subpart. Engineer Review N104500030: Salt Lake City Department of Airports - Salt Lake City International Airport December 29, 2023 Page 21 [Last updated October 17, 2023] 3. Comment regarding Title V: Title V of the 1990 Clean Air Act (Title V) applies to the following: 1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source. This facility is not a major source and is not a Title IV source. The facility is subject to 40 CFR 60 (NSPS) and 40 CFR 63 (MACT) regulations. It is not subject to 40 CFR 61 (NESHAP) regulations. NSPS Subparts IIII, JJJJ, and MACT subpart ZZZZ and CCCCCC exempts sources from the obligation to obtain a permit under a Title V permit, if the source is not otherwise required by law to obtain a permit. While NSPS subpart Dc does no exempt sources from obtaining a Title V permit, the applicable facilities under this subpart do not have any emission limitations, only recordkeeping requirements. Therefore, this subpart does not require the source to obtain a Title V permit. There are no other reasons why this source would be required to obtain a part 70 permit; therefore, Title V does not apply to this facility as per R307-415-4(2)(c). [Last updated November 22, 2023] 4. Comment regarding Changes in this modification: This modification has resulted in the following changes to DAQE-AN104500029-22: 1. A net increase in emissions occurred with the addition of three new generators and the removal of two existing generators. Emission totals were updated to account for this increase. 2. Equipment items II.A.38 was updated, as the listed engine rating was not accurate and was lower than what was listed in the permit. The engine capacity was updated to 375 kW from 400 kW. 3. The source provided an administrative update to the location of equipment listed in condition II.A.17, changing the location from Pump Station #5 to the North Support area. 4. The 350 kW engine previously listed in condition II.A.19 at the "New Terminal Tunnel" location and the 375 kW engine previously listed in condition II.A.20 have both been removed from the facility, and emissions were adjusted to reflect this removal. 5. Condition II.B.3.c has been updated as a result of updated modeling provided for this modification, and to account for changes in the equipment list. 6. The three 8,000 gallon storage tanks were added to the end of the equipment list as two separate equipment items, one for the two diesel storage tanks and one for the gasoline storage tank. 7. The new 450 kW generator engine was added as equipment item II.A.20, and the two new 1500 kW generators were added as equipment item II.A.44. The different locations in the permit were chosen to maintain some organizational consistency in engine sizes and placement in the equipment list. 8. Condition II.B.1.d.1 was updated remove the requirement to keep track of natural gas consumption for the four 25 MMBtu/hr boilers, as there is no associated limit on natural gas Engineer Review N104500030: Salt Lake City Department of Airports - Salt Lake City International Airport December 29, 2023 Page 22 consumption for the boilers. 9. Condition II.B.1.i was added to enforce BACT for the three new ASTs. [Last updated December 1, 2023] 5. Comment regarding Modeling methodology: During review of the permit, the question of what engines are selected to be modeled came up, as well as the question of why certain engines have restrictions whereas others do not. The modeled engines are the 13 engines rated 1000 kW or higher, plus a 450 kW engine and 300 kW engine that are close enough to one of the larger engines to require modeling evaluation of their impacts. The engines that are not restricted in use as a result of the model are larger engines with higher hourly emission rates. However, these engines also have a much higher airflow rate from the engine stack. This parameter causes the engine plume to rise higher, which causes better dispersion from pollutants, and means less of the plume reaches the ground where the highest impacts on the atmosphere occur due to low winds. The engines modeled as "20GEN1A, 41GEN1B, 41GEN1E, 41GEN1G, 15KWA, and 15 KW_B" all operate with a significantly higher engine flow rate compared to the engines restricted by the model, with all except 20GEN1A having a flow rate of over 100 m/s. 20GEN1A has a flow rate of 86.82 m/s, which is still significantly higher than the restricted engines, which have an engine flow rate of around 55 m/s. All other engines in the permit are not included in the model because they are not large enough to cause a significant impact on the 1-hour NO2 NAAQS.

As the mentioned sources would not be modified, they are not part of this application. 2 Permit condition numbers coincide with conditions in Approval Order (AO) DAQE-AN104500028-21 Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Emissions Calculations 3 Ramboll Confidential 3. EMISSIONS CALCULATIONS Pollutants emitted from the facility include NOX; CO; VOCs; sulfur dioxide (SO2); particulate matter (PM); PM less than 10 microns in diameter (PM10); PM less than 2.5 microns in diameter (PM2.5); hazardous air pollutants (HAPs); and greenhouse gases, represented in terms of carbon dioxide equivalents (CO2e). The methodology used to estimate potential emissions is discussed in the following sections. The manufacturer’s specification sheets for the generator are provided in Appendix C, and detailed calculations are provided for the proposed generators in Appendix D. 3.1 New Diesel-Fired Emergency Standby Generators Operation of the diesel-fired emergency generator engines would result in emissions of products of combustion. The derivation of potential hourly and annual emissions is presented below. 3.1.1 Derivation of Potential Hourly Emissions The following emission factors were used to estimate the potential hourly emissions from the emergency generators:  The manufacturer’s engine-specific emission factors for NOX, VOC (hydrocarbons), CO, and filterable PM were used to estimate the emissions of those pollutants at each generator load. If engine-specific emission factors were not available, emission factors from AP-42 Chapter 3.3 Gasoline And Diesel Industrial Engines and Chapter 3.4, Large Stationary Diesel and All Stationary Dual-fuel Engines were conservatively used.3,4 It was conservatively assumed that all particulate matter in the engine exhaust is PM2.5. Individual emission factors for NOx and Non- methane hydrocarbons (NMHC) were determined using a NOx/NMHC ratio of 95% to 5%, per USEPA’s federal emission standards referenced in TCEQ’s Emissions Reductions Plan.5 Conversion from NMHC to VOC emissions are based on guidance from USEPA’s conversion factors for hydrocarbon emission components.6 Potential hourly emissions were based on the maximum hourly emission rate for each pollutant at any engine load for each engine group.  Emissions of SO2, CO2, and HAPs were estimated based on the diesel fuel emission factors in the USEPA’s AP-42, Chapter 3.4, Large Stationary Diesel and All Stationary Dual-fuel Engines. The emission factor for SO2 was calculated based on the maximum allowable diesel fuel sulfur content of 0.0015% by weight, per 40 CFR 60 Subpart IIII (see Section 0 of this report).

Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 6 Ramboll Confidential 4. FEDERAL AND STATE REGULATORY APPLICABILITY The following sections outline the federal and state air regulations that are potentially applicable to the facility. Specifically, requirements under the federal NSR permitting program, Title V of the Clean Air Act Amendments, New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAP), Chemical Accident Prevention Provisions, and the UAC are discussed herein. 4.1 New Source Review The federal NSR permitting program regulates emissions from major stationary sources of regulated air pollutants. NSR is comprised of two elements: Nonattainment NSR (NNSR) and Prevention of Significant Deterioration (PSD). NNSR permitting is applicable in areas that have been designated as nonattainment for a regulated pollutant under the National Ambient Air Quality Standards (NAAQS). PSD permitting applies in areas that have been designated as attainment or unclassifiable. The facility is located in Salt Lake County, which has been designated as serious nonattainment for PM2.5,8 moderate nonattainment for ozone, and as attainment or unclassifiable for all other criteria pollutants.9,10 As such, NNSR is the potentially applicable program for ground-level ozone formation (VOCs and NOX), PM2.5, and precursors for the formation of PM2.5, which include NOX, SO2, and VOC. PSD is the applicable permitting program for all other criteria pollutants at the facility. The NSR major source threshold for Salt Lake County is 70 tpy for PM2.5 and each of its precursor pollutants (NOX, SO2, and VOC).11,12 Additionally, pursuant to UAC R307-420, the Major Source threshold for VOC is 50 tpy in Salt Lake County. Although UAC R307-420 is only applicable when Salt Lake County is classified as in attainment for ozone, SLCDA has conservatively assumed the Major Source threshold for VOC is 50 tpy. As shown in Table 1, the potential emissions from operations at the facility for each of these pollutants would be less than the applicable major source thresholds. The facility is also classified as a minor source with respect to PSD, and the facility-wide potential emissions for all NSR-regulated criteria pollutants would be less than the major source threshold of 100 tpy, pursuant UAC R307-101-2.13 4.2 Title V Operating Permits The Title V operating permits program, promulgated in 40 CFR 70, requires a facility to obtain a Title V operating permit if it has potential emissions of a regulated criteria pollutant exceeding 100 tpy, of any single HAP exceeding 10 tpy, or of the aggregate of all HAPs exceeding 25 tpy. However, as discussed in Section 4.1, the Title V major source thresholds for PM2.5 and its precursor pollutants are at a lower threshold of 70 tpy in Salt Lake County since the area is designated as serious non-attainment for PM2.5. Additionally, pursuant to 8 UDAQ submitted a PM2.5 Maintenance Plan based on a Clean Data Determination and, as such, the redesignation to a maintenance area is pending. 9 40 CFR 81.345 10 Salt Lake County was redesignated to a maintenance area for PM10 on March 27, 2020. 11 Utah Administrative Code.

R307-101: General Requirements. https://rules.utah.gov/publicat/code/r307/r307- 101.htm Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 7 Ramboll Confidential UAC R307-420, the Major Source threshold for VOC is 50 tpy in Salt Lake County. Although UAC R307-420 is only applicable when Salt Lake County is classified as in attainment for ozone, SLCDA has conservatively assumed the Major Source threshold for VOC is 50 tpy. Facility-wide potential emissions would be less than 100 tpy each for all criteria pollutants, less than 70 tpy each for PM2.5 and its precursors, less than 50 tpy for VOC, and less than the applicable major source thresholds for HAPs. As such, the facility would continue to be classified as a synthetic minor source of air emissions with respect to the Title V program. 4.3 New Source Performance Standards NSPS, promulgated in 40 CFR 60, provide emissions standards for criteria pollutant emissions from new, modified, and reconstructed sources. The following sections discuss the NSPS that are potentially applicable to the proposed generators and fuel storage tanks. 4.3.1 40 CFR 60 Subpart A – General Provisions NSPS Subpart A provides generally applicable requirements for testing, monitoring, notifications, and recordkeeping. Any source that is subject to another subpart under 40 CFR 60 is also subject to Subpart A, unless otherwise stated in the specific subpart. 4.3.2 40 CFR 60 Subpart K – Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After June 11, 1973, and Prior to May 19, 1978 NSPS Subpart K is applicable to petroleum storage tanks which were constructed, reconstructed, or modified between June 1973 and May 1978, and which have a storage capacity greater than 40,000 gallons.14 The facility would maintain aboveground fuel storage tanks for the proposed generators; however, each of these tanks are new units constructed after 1978. Furthermore, none of the tanks would have a storage capacity greater than 40,000 gallons. Therefore, NSPS Subpart K provisions do not apply. 4.3.3 40 CFR 60 Subpart Ka – Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After May 18, 1978, and Prior to July 23, 1984 Similar to NSPS Subpart K, NSPS Subpart Ka is applicable to petroleum storage tanks which were constructed, reconstructed, or modified between May 1978 and July 1984, and which have a storage capacity greater than 40,000 gallons.15 As previously discussed, the proposed aboveground diesel storage tanks are new units constructed after 1984. Further, none of the diesel tanks would have a storage capacity greater than 40,000 gallons. Therefore, NSPS Subpart Ka is also not applicable. 4.3.4 40 CFR 60 Subpart Kb – Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984 NSPS Subpart Kb applies to volatile organic liquid (VOL) storage vessels which were constructed, reconstructed, or modified after July 1984. VOL storage tanks are only subject to this rule if they meet one of the following criteria:16 14 40 CFR 60.110 15 40 CFR 60.110a 16 40 CFR 60.110b(b) Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 8 Ramboll Confidential  The storage vessel has a maximum storage capacity greater than or equal to 151 m3 (39,890 gallons) and which stores a VOL with a maximum true vapor pressure exceeding 3.5 kPa (0.51 psia); or  The storage vessel has a maximum storage capacity greater than or equal to 75 m3 (19,812.9 gallons) but less than 151 m3 and which stores a VOL with a maximum true vapor pressure exceeding 15.0 kPa (2.2 psia). The new fuel storage tanks would all have a storage capacity less than 19,812.9 gallons, therefore, NSPS Subpart Kb does not apply. 4.3.5 40 CFR 60 Subpart IIII – Stationary Compression Ignition Internal Combustion Engines NSPS Subpart IIII applies to new, modified, and reconstructed compression ignition (CI) internal combustion engines (ICE). New engines are subject to this regulation if construction of the CI ICE commenced after July 11, 2005, and if the engine was manufactured after April 1, 2006, for CI ICE that are not fire pump engines, or July 1, 2006, for CI ICE that are fire pump engines.17 This rule is applicable to the proposed CI ICE that would be operated at the facility. The proposed generator would meet the definition of emergency stationary ICE in 40 CFR 60.4219 and would not operate as a fire pump engine. 4.3.5.1 Emission Standards The proposed generators would be classified as emergency generators under this regulation and would each have a displacement of less than 10 liters per cylinder. Per 40 CFR 60.4205(b), the generators would be subject to the applicable emission standards in 40 CFR 89.112-113. The Tier 2 emission standards for nonroad engines with a rated power greater than 560 kW are summarized in Table 2.18 The USEPA Tier 2 standards for nonroad engines are based on a weighted cycle and cannot be used for comparison to the actual emissions from the engine at a specific load. Table 2. Tier 2 Emission Standards1 Pollutant Emission Standard (g/kW-hr) NOX + Non-Methane Hydrocarbons (NMHC) 6.4 CO 3.5 PM 0.20 Notes: 1) Obtained from 40 CFR 89.112 (a), Table 1 for Tier 2 engines rated >560 kW. 17 40 CFR 60.4200(a)(2) 18 40 CFR 89.112(a), Table 1. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 9 Ramboll Confidential Additionally, the facility is required to only combust in its generators fuel that complies with the following requirements in 40 CFR 80.510(b) for nonroad diesel fuel:19  Maximum sulfur content of 15 ppm; and  Either a minimum cetane index of 40 or a maximum aromatic content of 35 volume percent. The applicant would comply with the emission standards in 40 CFR 89.112-113 by purchasing engines certified by the manufacturer to comply with the Tier 2 emission standards.20 Further, the site would operate and maintain the engine according to the manufacturer’s emission-related written instructions and only change those emission-related settings that are permitted by the manufacturer.21 4.3.5.2 Run Time Restrictions for Emergency ICE In order for a stationary engine to be considered an emergency ICE under NSPS Subpart IIII, it must meet the run time restrictions in 40 CFR 60.4211(f). There is no restriction on usage of an emergency ICE in emergency situations.22 Each engine is restricted to a maximum of 100 hours per calendar year of operation for maintenance checks and readiness testing.23 Each engine is allowed up to 50 hours per calendar year of non-emergency operation other than maintenance and testing; however, any non-emergency run time must be counted as part of the 100 hours per calendar year for maintenance and testing.24 Any other operations are prohibited. The facility would equip each emergency ICE with a non-resettable hour meter prior to startup of the unit in order to verify compliance with the run time restrictions for emergency and non-emergency runs.25 4.3.5.3 Notifications, Reporting, and Recordkeeping An Initial Notification under NSPS Subpart A is not required for emergency stationary ICE. The facility would retain records of the emergency and non-emergency runs for the engine for a minimum of two years, as recorded through the engine’s non-resettable hour meter. The records would indicate the time of operation of the engine and the reason the engine was in operation during that time.26 4.3.6 40 CFR 60 Subpart JJJJ – Stationary Spark Ignition Internal Combustion Engines NSPS Subpart JJJJ is applicable to new, modified, and reconstructed stationary spark ignition (SI) ICE. The proposed generator would be categorized as a CI ICE. As such, NSPS Subpart JJJJ does not apply. 19 40 CFR 60.4207(b) 20 40 CFR 60.4211(c) 21 40 CFR 60.4211(a) 22 40 CFR 60.4211(f)(1) 23 40 CFR 60.4211(f)(2)(i).

A facility that has potential emissions exceeding 10 tpy for any individual HAP and/or emissions exceeding 25 tpy for the sum of all HAP is classified as a major source of HAP emissions. A facility that is not a major source of HAP is classified as an area source. The facility would continue to be classified as an area source with the proposed modifications because it has potential HAP emissions less than the major source thresholds. The following sections discuss the potentially applicable NESHAP standards for the proposed generator and storage tanks. 4.4.1 40 CFR 63 Subpart A – General Provisions NESHAP Subpart A provides generally applicable requirements for testing, monitoring, notifications, and recordkeeping. Any source that is subject to another subpart under 40 CFR 63 is also subject to Subpart A, unless otherwise stated in the specific subpart. 4.4.2 40 CFR 63 Subpart EEEE – Organic Liquids Distribution (Non-Gasoline) NESHAP Subpart EEEE is applicable to organic liquids distribution operations, including organic liquid storage tanks, located at major sources of HAP emissions.27 This regulation does not apply as the facility would continue to be classified as an area source of HAP emissions. 4.4.3 40 CFR 63 Subpart ZZZZ – Stationary Reciprocating Internal Combustion Engines NESHAP Subpart ZZZZ applies to new and existing stationary reciprocating internal combustion engines (RICE) located at both major and area sources of HAP emissions. Per 40 CFR 63.6590(c), for new or reconstructed stationary RICE located at an area source of HAP emissions, the only requirement under NESHAP Subpart ZZZZ is to meet the requirements of NSPS Subpart IIII for CI ICE and of NSPS Subpart JJJJ for SI ICE. Since the proposed CI ICE at the facility would be in compliance with NSPS Subpart IIII, the unit would also be in compliance with NESHAP Subpart ZZZZ. No further requirements apply for this engine under this regulation. 4.5 Chemical Accident Prevention Provisions The Chemical Accident Prevention Provisions, promulgated in 40 CFR 68, provide requirements for the development of risk management prevention (RMP) plans for regulated substances. Applicability to RMP plan requirements is based on the types and amounts of chemicals stored at a facility. Neither gasoline or diesel fuel is on the list of regulated substances in Subpart F of this rule; therefore, the facility is not required to develop an RMP plan under 40 CFR 68. 4.6 Utah Administrative Code, Title R307 – Environmental Quality, Air Quality In addition to the federal regulations, Title R307 of the UAC establishes regulations applicable at the emission unit level and at the facility level. The state regulations in Chapter 2 also include general requirements for facilities, such as the requirement to obtain permits to construct and operate. Source-specific standards in R307 that are potentially applicable to the proposed generator are discussed in the following sections. 27 40 CFR 63.2330 Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 11 Ramboll Confidential 4.6.1 R307-203 – Emission Standards: Sulfur Content of Fuels This regulation provides emission standards for fuel burning equipment that combusts coal, oil, or a mixture thereof. The rule does not apply to sources covered by a NSPS for sulfur emissions. While the NSPS that regulates the emergency generator engines, 40 CFR 60 Subpart IIII, does not specifically regulate sulfur emissions, it does provide a requirement for the fuel sulfur content of the diesel fuel combusted in the engines (maximum sulfur content of 0.0015% by weight). The NSPS Subpart IIII fuel sulfur content limit is more stringent than that contained in this regulation (i.e., 0.85 pounds per million British thermal unit [lb/MMBtu]). Therefore, the NSPS Subpart IIII fuel sulfur content limitation applies in lieu of the R307-203 limitation. 4.6.2 R307-305-3 – Nonattainment and Maintenance Areas for PM10: Emission Standards – Visible Emissions This rule sets standards for visible emissions in PM10 nonattainment and maintenance areas, including Salt Lake County. R307-305-3(3) states that visible emissions from diesel engines in stationary operation shall be of a shade or density no darker than 20% opacity, not exceeding three minutes in any hour.28 The proposed emergency generators would be subject to this standard. R307-305-3(4) further clarifies that visible emissions exceeding the opacity standards for short time periods as the result of initial warm-up, caused by start-up or shutdown of a facility, installation or operation, or unavoidable combustion irregularities which do not exceed three minutes in length shall not be deemed in violation, provided that UDAQ finds that adequate control technology has been applied. The applicant would be required to minimize visible and non-visible emissions during start-up or shutdown, installation, or operation through the use of adequate control technology and proper procedures. Such requirements would be satisfied through exclusive use of ultra-low sulfur diesel fuel in all generator engines onsite consistent with NSPS Subpart IIII requirements. 4.6.3 R307-309 – Nonattainment and Maintenance Areas for PM10 and PM2.5: Fugitive Emissions and Fugitive Dust This rule sets standards for control of fugitive dust and fugitive emissions in PM10 and PM2.5 nonattainment and maintenance areas, including Salt Lake County. R307-309-4 states that fugitive emissions from any source shall not exceed 15% opacity. During operation, the proposed facility would not be a source of fugitive dust since it would not have unpaved roads in operational areas and would not engage in the handling of dust generating bulk materials. 4.6.4 R307-401 – Permits: New and Modified Sources R307-401 establishes application and permitting requirements for new installations and modifications to existing installations throughout the State of Utah. As a minor source for all criteria pollutants (and associated precursor pollutants) located in a nonattainment area, the facility is categorically subject to the provisions of R307-401. The applicant would continue to comply with all generally applicable requirements found under R307-401 as evidenced in the supporting sections of this NOI application. Additional provisions that apply to modifications to existing installations located in nonattainment areas are found under R307- 403, discussed subsequently. 28 Unavoidable combustion irregularities which exceed three minutes in length must be handled in accordance with R307-107. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 12 Ramboll Confidential 4.6.5 R307-403 – Permits: New and Modified Sources in Nonattainment Areas and Maintenance Areas R307-403 implements the provisions of the federal nonattainment area permitting program for major sources as required by 40 CFR 51.165. The requirements under R307-403-5(1) apply to new or modified sources located in a PM10 nonattainment area that have the potential to emit more than 25 tpy of combined PM10, SO2, and NOX emissions. Salt Lake County is currently designated as attainment for PM10, so R307-403-5(1) is not applicable. Per R307-403-5(2), major sources or major modifications to existing sources located in a PM2.5 nonattainment areas must obtain ERCs. As demonstrated in Table 1, the proposed modifications would not cause the facility to be classified as a major source and the project itself would not meet the definition of a major modification to existing sources. Therefore, the requirement to obtain ERCs prior to initiating construction does not apply. 4.6.6 R307-410 – Emissions Impact Analysis The provisions of R307-410 establish the procedures and requirements for evaluating the emissions impact of new and modified sources that require an approval order under R307- 401 to ensure that the source would not interfere with the attainment or maintenance of any NAAQS in the state of Utah. The facility’s potential emissions with the newly proposed generators would not exceed any of the modeling thresholds under R307-410-4 Table 1. However, SLCDA understands that UDEQ would like the applicant to demonstrate compliance with the 1-hour NO2 NAAQS since the proposed facility modification’s NOx emissions will exceed 10 pounds per hour. SLCDA has conducted an air dispersion modeling analysis using USEPA’s recommended short-range transport dispersion model (i.e., AERMOD). This analysis was conducted in accordance with the air dispersion modeling protocol submitted to UDAQ on June 14, 2023.29 The facility’s demonstration of compliance with the 1-hour NO2 and annual NAAQS is shown in the final modeling report, provided to UDAQ under separate cover, and is summarized in Section 6. 4.6.7 R307-420 – Permits: Ozone Offset Requirements in Davis and Salt Lake County Counties Section R307-420-1 indicates that this regulation becomes effective only when Salt Lake and Utah counties are redesignated into attainment for ozone. Additionally, this regulation only applies to major sources or major modifications as defined in R307-420-2. Since the facility is not a major source and this project is not considered a major modification, the facility is not subject to this regulation. 4.6.8 R307-421 – Permits: PM10 Offset Requirements in Salt Lake County and Utah County Section R307-421-5 indicates that this regulation becomes effective only when Salt Lake and Utah counties are redesignated into attainment for PM10. Salt Lake County was redesignated as attainment for PM10 on March 27, 2020, and so this regulation is applicable. The combined emissions increase of PM10, SO2, and NOX attributable to the proposed generators at the facility is less than the 25 tpy threshold; therefore, the requirement to obtain ERCs prior to initiating construction does not apply. 29 The Modeling Protocol was approved by Dave Prey on January 4, 2022. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Evaluation of Best Available Control Technology 13 Ramboll Confidential 5. EVALUATION OF BEST AVAILABLE CONTROL TECHNOLOGY New and modified sources of air emissions in Utah are required to implement best available control technology (BACT) for control of emissions when applying for an AO.30 Determination of BACT includes analyses pertaining to technical feasibility of potential air pollution control technologies, as well as factors such as the energy, environmental, and economic impacts of the technology. This section evaluates BACT for emissions of criteria pollutants from the emergency generators and ASTs, specifically NOX, CO, VOC, PM10, PM2.5, and SO2. The emergency backup generator to be installed at the facility would be certified by the manufacturer to meet the requirements of USEPA’s Tier 2 emission standards, in accordance with the requirements of 40 CFR 60 Subpart IIII. The primary pollutant of concern is NOX, as indicated by the potential emissions of the emergency backup generators and local attainment considerations (i.e., NOX is a precursor pollutant for secondary formation of ozone, PM10, and PM2.5). Because the emergency backup generator would operate in standby mode the majority of the time, the use of engines certified by the manufacturer to meet the Tier 2 standards satisfies BACT requirements for this scenario. However, to be proactive, the applicant has evaluated additional potential control technologies that can reduce NOX emissions. The three (3) ASTs to be installed at the facility would comply with Utah Rule R307-401-8, with emission limits for storage tanks being 8.66 tpy of VOCs and 1.93 tpy of HAPs. The primary pollutant of concern is VOCs, as indicated by the potential emissions of the ASTs and local attainment considerations (i.e., VOCs are a precursor pollutant for secondary formation of ozone). The applicant has evaluated potential control technologies to reduce VOC emissions from the fuel ASTs. 5.1 Engine BACT Determination for NOX In accordance with the USEPA’s top-down approach for conducting BACT analyses, the applicant has reviewed potential control technologies for reducing NOX emissions from diesel- fired ICE. Of all potential technologies, those technically capable of reducing NOX emissions from diesel-fired ICE of equivalent capacity to those used at the facility include the use of (1) Selective Catalytic Reduction (SCR), (2) engines certified by the manufacturer to the USEPA’s Tier 4 emissions standards under 40 CFR 60 Subpart IIII, and (3) engines certified by the manufacturer to the USEPA’s Tier 2 emission standards under 40 CFR 60 Subpart IIII. The following sections evaluate these potential NOX control technologies for determination of BACT. 5.1.1 Evaluation of SCR SCR achieves a reduction in NOX emissions by passing a stream of urea solution into the generator exhaust, in the presence of a fixed, solid catalyst. The urea reacts with the NOX yielding nitrogen, water, and CO2. The applicant has evaluated the control effectiveness and potential energy, environmental, and economic impacts in the following subsections. 30 R307-401-5(d) Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential SCR Control Effectiveness The control efficiency of this technology is dependent on several factors including generator load, catalyst state, and exhaust temperature. The SCR controls evaluated are estimated to achieve up to a 90% reduction in NOX emissions31, which would equate to a NOX emissions rate of 0.44 g/bhp-hr (1.94 lb/hr/generator) for the Cummins generator. To ensure the SCR systems operate effectively, the unit must be operated and maintained in accordance with the manufacturer’s recommendations. However, per the California Air Resources Board’s (ARB) review on stationary compression ignition engines, it is stated that since SCR’s require exhaust temperatures of 260°C to 540°C (500°F-1,004°F), it may be difficult for emergency generators to meet these temperatures since most of their operations are on low loads and for short periods of time32. Therefore, if the exhaust temperature was not met for these runs, the SCR would not activate, and the desired NOX reduction would not be met. Additionally, an increase in load size or run duration for the activation of the SCR would result in additional emissions from the engine. Evaluation of Energy Impacts of SCR The energy required to operate SCR after-treatment is minimal relative to that of a generator. During the winter months, there would be a small input of energy into the SCR unit to prevent freezing of the urea solution. Evaluation of Environmental Impacts of SCR During operation of the SCR unit, the reaction of NOX, urea, and oxygen would result in the formation of CO2 emissions to the atmosphere, in addition to the formation of nitrogen and water vapor emissions. However, the amount of CO2 emissions from urea usage is a minor contributor to the overall GHG emissions from the engine resulting from diesel combustion, and the environmental impact of the additional CO2 emissions is more than offset by the benefit of NOX reduction. Additionally, the SCR process requires the installation of reagent storage facilities, a system capable of metering and diluting the stock reagent into the appropriate solution, and an atomization/injection system at the appropriate locations in the combustion unit. Evaluation of Economic Impacts of SCR The economic impact of installing SCR technology is significant. The procurement and installation process would consume a large amount of capital, and there would also be long- term costs associated with the maintenance, repair, consumables, and catalyst storage and regeneration associated with operating the SCR units. California’s ARB also researched the cost associated with installing diesel particulate filters (DPF) and SCRs on new Tier 2 or Tier 3 engines33. The following costs were determined based on engine size and SLCDA has conservatively assumed that the cost for SCR installation, without DPF, is equal to the difference in cost between the DPF and DPF/SCR scenario, as shown in Table 3 below. 31 Based on the maximum control efficiency from USEPA’s Air Pollution Control Technology Fact Sheet, Selective Catalytic Reduction (SCR), USEPA-452/F-03-032. https://www3.epa.gov/ttn/catc/cica/files/fscr.pdf 32 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf 33 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential Table 3.

According to CARB data, SCR would result in an additional $210,000 each for the new 1,500 kW (2,012 hp) engines. This would result in ~$145,000/ton NOX removed. Additionally, this does not account for the ongoing operation and maintenance costs of the SCR system. 5.1.2 Evaluation of USEPA Tier 4 Certification 40 CFR 60 Subpart IIII requires owners and operators of new non-emergency diesel-fired ICE with a rated power output of greater than 560 kW to purchase engines that are certified by the manufacturer to the USEPA’s Tier 4 nonroad engine emission standards. As such, the proposed diesel-fired emergency backup generator to be installed at the site is not subject to Tier 4 certification. However, for completeness, the applicant has reviewed the potential use of Tier 4-certified engines at the site as a means of demonstrating BACT-level NOX emissions. For the purposes of evaluating potential NOX emissions control technologies, the applicant considers the use of Tier 4-certified engines to be effectively equivalent from an emissions performance perspective to the use of Tier 2-certified engines utilizing SCR for NOX emissions control. According to the California ARB, a Tier 4 engine supplied by a manufacturer with a DPF and SCR would be an additional $310,000 for each of the new 1,500 kW engines.34 5.1.3 Evaluation of USEPA Tier 2 Certification 40 CFR 60 Subpart IIII requires owners and operators of new emergency diesel-fired ICE to purchase engines certified by the manufacturer to the USEPA’s nonroad engine emission standards. Since the use of Tier 2-certified engines does not involve an exhaust stream control technique, there are no associated adverse environmental, energy, or economic impacts. 34 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential 5.1.4 Selection of BACT for NOX Based on a limited review of USEPA’s RACT/BACT/LAER Clearinghouse (RBLC) database for diesel generators, the use of either Tier 4 engines or Tier 2 engines with SCR represents the lowest achievable emission rate (LAER) level of emission control for emergency backup generators and exceeds the BACT requirements of this minor source project. In reviewing the control techniques described above, SLCDA has determined that the Tier 2 engines meet BACT for NOX by implementing good operating practices and through purchasing an engine certified to the required Tier 2 emissions standards. Although the Tier 4 engine and Tier 2 engines with SCR are technically feasible, due to the low potential emission reduction for the generators and the high capital and annual operating costs, these options were determined to be economically infeasible. 5.2 Engine BACT Determination for Other Criteria Pollutants Emissions of all other criteria pollutants would be less than 1 tpy for each emergency generator. Due to the low emission rates of these pollutants, they do not warrant control technology beyond those inherent to Tier 2 generators, which is considered BACT for this facility. This conclusion is consistent with the USEPA’s determination in the development of 40 CFR 60 Subpart IIII that add-on controls are not economically viable for emergency ICE. While the use of Tier 4-certified engines could potentially lower emissions of PM, the conservatively estimated potential generator emissions of PM are already minimal (0.04 tpy versus a major source threshold of 70 tpy) and are based on the maximum ratio of the manufacturer’s “Not to Exceed” emission factor, which is approximately 25% higher than the manufacturer’s “nominal” or expected emission factors. As such, the use of and significant costs associated with installing a Tier 4-certified engine would be expected to result in only minimal reductions of PM emissions (e.g., less than 0.5 tpy) at the site. Consequently, the applicant considers the use of Tier 2-certified engines to represent BACT for all other criteria pollutants. The proposed generators are certified by the manufacturer to the USEPA’s Tier 2 emissions standards, and the site will operate and maintain each engine according to the manufacturer’s emission-related written instructions and only change those emission-related settings that are permitted by the manufacturer. Further, the applicant will only combust ultra-low sulfur diesel fuel in its generators, with a maximum fuel sulfur content of 0.0015% by weight consistent with the requirements of NSPS Subpart IIII. 5.3 Engine BACT Conclusion The emergency generator engines to be installed at the facility are certified by the manufacturer to meet the requirements of USEPA’s Tier 2 emission standards, in accordance with the requirements of 40 CFR 60 Subpart IIII. The primary pollutant of concern from this generator is NOX, as indicated by the potential emissions and local attainment considerations as a precursor for ozone, PM10, and PM2.5. Because this emergency generator would be in standby mode the majority of the time and typically run for short periods of time, the use of engines certified by the manufacturer to meet the Tier 2 standards satisfies BACT requirements for this scenario. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential 5.4 AST BACT Determination for VOCs The applicant has also prepared a BACT analysis in accordance with the USEPA’s top-down approach for VOC emissions from the three (3) proposed ASTs. Of the three proposed ASTs, one will contain unleaded gasoline; the other two will be diesel tanks. The VOC control technologies for ASTs considered include (1) stage 1 vapor recovery, (2) white or aluminum exterior surfaces that are exposed to sunlight, (3) submerged filling, and (4) best management practices. 5.4.1 Stage 1 Vapor Recovery Stage I vapor recovery is a control strategy to capture gasoline vapors that are released when gasoline is delivered to a storage tank. When a fuel tank is being filled, the newly added liquid displaces the vapor that is in equilibrium with whatever quantity of liquid is present in the tank at the time of filling. The concentration of this vapor phase is a function of temperature, pressure, and the vapor pressure of the fuel. In stage 1 vapor recovery, the displaced vapor is returned to the loading truck and sent back to the fuel supplier for further processing or combustion. Utah establishes requirements for stage 1 vapor recovery of stationary gasoline tanks in R307-328-5, which mandates vapor recovery systems with 90% control efficiencies for tanks that exceed a throughput of 10,000 gallons in any one month period. The proposed gasoline tanks at SLCDA are not subject to this rule because they will have monthly throughputs of less than 10,000 gallons. This rule is not applicable to diesel tanks. 5.4.2 White or Aluminum Exterior Surfaces VOC emissions from fuel storage tanks can be greatly influenced by their exterior color. Darker paint colors absorb more radiant heat from the sun, which then transfers thermal energy to the tanks contents. When the temperature of the fuel rises, the concentration of fuel in the gas phase within the tank will increase, which leads to greater standing and working losses. Fuel tanks are often painted with light colors to reflect solar insolation, thereby maintaining lower temperatures inside the tank. The three (3) proposed ASTs have a white enamel coating, which will contribute to the reduction of standing and working losses. In addition, the proposed tanks are UL-2085 Fireguard© units that are thermally protected with a double-wall construction and a 3-inch (minimum) interstice that will bolster the tanks insulative properties.35 5.4.3 Submerged Filling The two primary methods for filling fuel tanks include splash filling and submerged filling. Submerged filling refers to the process of filling a tank by pumping the new fluid beneath the surface of the existing liquid. Splash filling is the procedure of filling a tank by adding additional liquid fuel above the surface of the existing liquid. Splash filling results in heavy turbulence, greater vapor/liquid contact, and more atomization; all of which amount to an increase in VOC emissions, relative to the submerged loading option. SLCDA will practice submerged filling with all three (3) proposed ASTs. 5.4.4 Best Management Practices Employing best management practices is essential to ensure proper, leak-free operation of fuel tanks. Best management practices for fuel tanks include: 35 Per AST exhibit.pdf, supplied by SLCDA in March 2023. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential 1. Regular inspections of the tank, checking for leaks, rust, bad seals, or signs of leakage. Checking fuel storage tanks and associated fittings/pipes for signs of corrosion and/or leaks can help prevent avoidable VOC losses. 2. Using fuel stabilizers when fuel is stored for long durations. In addition to preventing direct fuel waste, fuel stabilizers can inhibit the oxidation of fuels into more corrosive compounds that may damage tanks over time and cause them to leak. SLCDA will adhere to best management practices with all proposed ASTs. 5.4.5 BACT Determination for VOC Emissions from ASTs Based on a limited review of USEPA’s RACT/BACT/LAER Clearinghouse (RBLC) database for stationary petroleum storage tanks, the use of best management practices and submerged filling represents the lowest achievable emission rate (LAER) level of emission control for the proposed gasoline and diesel ASTs. One tank in the RBLC query utilized stage 1 vapor recovery, however, per R307-328, the proposed ASTs are not required to implement stage 1 vapor recovery as the throughput will be less than 10,000 gallons per calendar month. In addition to implementing submerged filling and best management practices, the proposed ASTs will have a white enamel finish and are thermally protected via a double-wall construction with a 3-inch (minimum) interstice around the inner tank, both being features which will contribute to lower fuel temperatures within the tank and thus fewer standing and working losses. SLCDA therefore concludes that white paint and the thermally guarded construction, submerged filling protocol, and best management practices constitute BACT in this case.

Please see responses below, as well as a revised NOI and spec sheet for the 1,500kW generators. 1. Burn Pit Source – There are emissions associated with the burn pit. However, since SLCDA is not able to locate the original emissions estimates that were used in the baseline emissions for the burn bit, we are conservatively assuming no emissions reduction from this equipment removal. 2. Generator spec sheets: a. For the 1,500 kW generators – Please refer to the attached NOI/spec sheets including emission factors. b. For the 450 kW generator – The spec sheet for this generator is rated at 450 kW (603 hp), but has a nameplate horsepower of 755 hp. To account for engine performance rather than rating, emissions were calculated using “Full Standby” emission factors and power output (661 hp), as shown in Appendix C, Table 1 from the submitted NOI. Would you like us to revise to use the nameplate horsepower (755 hp)? 3. Regarding the decimal places for the emission summary (Table 1) on pages 8 and 60 (now page 64) - We have revised these to include two decimal places as requested.

I. OBJECTIVE Salt Lake City Airport Authority (Applicant) is seeking a modified approval order for their Salt Lake City Airport, located in Salt Lake County, Utah. This report, prepared by the Staff of the New Source Review Section (NSR), contains a review of the air quality impact analysis (AQIA) including the information, data, assumptions and modeling results used to determine if the facility will be in compliance with applicable State and Federal concentration standards. II. APPLICABLE RULE(S) Utah Air Quality Rules: R307-401-6 Condition for Issuing an Approval Order R307-410-3 Use of Dispersion Models R307-410-4 Modeling of Criteria Pollutants in Attainment Areas III. MODELING METHODOLOGY A. Applicability Emissions from the facility include PM10, NOx, CO, SO2, and HAPs. This modeling is part of a modified approval order. The emission rates for NOx triggered the requirement to model under R307-410. Modeling was performed by the UDAQ. Department of Environmental Quality Kimberly D.

Topography/Terrain The Plant is at an elevation 4224 feet with terrain features that have an affect on concentration predictions. a. Zone: 12 b. Approximate Location: UTM (NAD83): 416843 meters East 4515457 meters North 2. Urban or Rural Area Designation After a review of the appropriate 7.5-minute quadrangles, it was concluded the area is “rural” for air modeling purposes. 3. Ambient Air It was determined the Plant boundary used in the AQIA meets the State’s definition of ambient air. 4. Building Downwash The source was modeled with the AERMOD model. All structures at the plant were used in the model to account for their influence on downwash. 5. Meteorology Five (5) years of off-site surface and upper air data were used in the analysis consisting of the following: Surface – Salt Lake Airport, UT NWS: 2016-2020 Upper Air – Salt Lake Airport, UT NWS: 2016-2020 6. Background The background concentrations were based on concentrations measured in Rose Park, Utah. 7. Receptor and Terrain Elevations The modeling domain used by the Applicant consisted of receptors including property boundary receptors. This area of the state contains mountainous terrain and the modeling domain has simple and complex terrain features in the near and far fields. Therefore, receptor points representing actual terrain elevations from the area were used in the analysis. DAQE- MN104500030-23 Page 3 8. Model and Options The State-accepted AERMOD model was used to predict air pollutant concentrations under a simple/complex terrain/wake effect situation. In quantifying concentrations, the regulatory default option was selected. 9.

EMISSIONS CALCULATIONS Pollutants emitted from the facility include NOX; CO; VOCs; sulfur dioxide (SO2); particulate matter (PM); PM less than 10 microns in diameter (PM10); PM less than 2.5 microns in diameter (PM2.5); hazardous air pollutants (HAPs); and greenhouse gases, represented in terms of carbon dioxide equivalents (CO2e). The methodology used to estimate potential emissions is discussed in the following sections. The manufacturer’s specification sheets for the generator are provided in Appendix C, and detailed calculations are provided for the proposed generators in Appendix D. 3.1 New Diesel-Fired Emergency Standby Generators Operation of the diesel-fired emergency generator engines would result in emissions of products of combustion. The derivation of potential hourly and annual emissions is presented below. 3.1.1 Derivation of Potential Hourly Emissions The following emission factors were used to estimate the potential hourly emissions from the emergency generators: • The manufacturer’s engine-specific emission factors for NOX, VOC (hydrocarbons), CO, and filterable PM were used to estimate the emissions of those pollutants at each generator load. If engine-specific emission factors were not available, emission factors from AP-42 Chapter 3.3 Gasoline And Diesel Industrial Engines and Chapter 3.4, Large Stationary Diesel and All Stationary Dual-fuel Engines were conservatively used.3,4 It was conservatively assumed that all particulate matter in the engine exhaust is PM2.5. Individual emission factors for NOx and Non- methane hydrocarbons (NMHC) were determined using a NOx/NMHC ratio of 95% to 5%, per USEPA’s federal emission standards referenced in TCEQ’s Emissions Reductions Plan.5 Conversion from NMHC to VOC emissions are based on guidance from USEPA’s conversion factors for hydrocarbon emission components.6 Potential hourly emissions were based on the maximum hourly emission rate for each pollutant at any engine load for each engine group. • Emissions of SO2, CO2, and HAPs were estimated based on the diesel fuel emission factors in the USEPA’s AP-42, Chapter 3.4, Large Stationary Diesel and All Stationary Dual-fuel Engines. The emission factor for SO2 was calculated based on the maximum allowable diesel fuel sulfur content of 0.0015% by weight, per 40 CFR 60 Subpart IIII (see Section 0 of this report). The emissions calculations assumed a diesel high heating value of 0.137 MMBtu/gal, based on AP- 42, Table 3.4-1, footnote a.7 3 US EPA. 1996.

Salt Lake County is currently classified as Moderate nonattainment for the Ozone standard. However, UAC does not have regulations codified for when Salt Lake County is designated as nonattainment, and therefore, the Major Source classification for VOC from UAC R307- 420 was used. 3) Utah Administrative Code.

Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 6 Ramboll Confidential 4. FEDERAL AND STATE REGULATORY APPLICABILITY The following sections outline the federal and state air regulations that are potentially applicable to the facility. Specifically, requirements under the federal NSR permitting program, Title V of the Clean Air Act Amendments, New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAP), Chemical Accident Prevention Provisions, and the UAC are discussed herein. 4.1 New Source Review The federal NSR permitting program regulates emissions from major stationary sources of regulated air pollutants. NSR is comprised of two elements: Nonattainment NSR (NNSR) and Prevention of Significant Deterioration (PSD). NNSR permitting is applicable in areas that have been designated as nonattainment for a regulated pollutant under the National Ambient Air Quality Standards (NAAQS). PSD permitting applies in areas that have been designated as attainment or unclassifiable. The facility is located in Salt Lake County, which has been designated as serious nonattainment for PM2.5,8 moderate nonattainment for ozone, and as attainment or unclassifiable for all other criteria pollutants.9,10 As such, NNSR is the potentially applicable program for ground-level ozone formation (VOCs and NOX), PM2.5, and precursors for the formation of PM2.5, which include NOX, SO2, and VOC. PSD is the applicable permitting program for all other criteria pollutants at the facility. The NSR major source threshold for Salt Lake County is 70 tpy for PM2.5 and each of its precursor pollutants (NOX, SO2, and VOC).11,12 Additionally, pursuant to UAC R307-420, the Major Source threshold for VOC is 50 tpy in Salt Lake County. Although UAC R307-420 is only applicable when Salt Lake County is classified as in attainment for ozone, SLCDA has conservatively assumed the Major Source threshold for VOC is 50 tpy. As shown in Table 1, the potential emissions from operations at the facility for each of these pollutants would be less than the applicable major source thresholds. The facility is also classified as a minor source with respect to PSD, and the facility-wide potential emissions for all NSR-regulated criteria pollutants would be less than the major source threshold of 100 tpy, pursuant UAC R307-101-2.13 4.2 Title V Operating Permits The Title V operating permits program, promulgated in 40 CFR 70, requires a facility to obtain a Title V operating permit if it has potential emissions of a regulated criteria pollutant exceeding 100 tpy, of any single HAP exceeding 10 tpy, or of the aggregate of all HAPs exceeding 25 tpy. However, as discussed in Section 4.1, the Title V major source thresholds for PM2.5 and its precursor pollutants are at a lower threshold of 70 tpy in Salt Lake County since the area is designated as serious non-attainment for PM2.5. Additionally, pursuant to 8 UDAQ submitted a PM2.5 Maintenance Plan based on a Clean Data Determination and, as such, the redesignation to a maintenance area is pending. 9 40 CFR 81.345 10 Salt Lake County was redesignated to a maintenance area for PM10 on March 27, 2020. 11 Utah Administrative Code.

Although UAC R307-420 is only applicable when Salt Lake County is classified as in attainment for ozone, SLCDA has conservatively assumed the Major Source threshold for VOC is 50 tpy. Facility-wide potential emissions would be less than 100 tpy each for all criteria pollutants, less than 70 tpy each for PM2.5 and its precursors, less than 50 tpy for VOC, and less than the applicable major source thresholds for HAPs. As such, the facility would continue to be classified as a synthetic minor source of air emissions with respect to the Title V program. 4.3 New Source Performance Standards NSPS, promulgated in 40 CFR 60, provide emissions standards for criteria pollutant emissions from new, modified, and reconstructed sources. The following sections discuss the NSPS that are potentially applicable to the proposed generators and fuel storage tanks. 4.3.1 40 CFR 60 Subpart A – General Provisions NSPS Subpart A provides generally applicable requirements for testing, monitoring, notifications, and recordkeeping. Any source that is subject to another subpart under 40 CFR 60 is also subject to Subpart A, unless otherwise stated in the specific subpart. 4.3.2 40 CFR 60 Subpart K – Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After June 11, 1973, and Prior to May 19, 1978 NSPS Subpart K is applicable to petroleum storage tanks which were constructed, reconstructed, or modified between June 1973 and May 1978, and which have a storage capacity greater than 40,000 gallons.14 The facility would maintain aboveground fuel storage tanks for the proposed generators; however, each of these tanks are new units constructed after 1978. Furthermore, none of the tanks would have a storage capacity greater than 40,000 gallons. Therefore, NSPS Subpart K provisions do not apply. 4.3.3 40 CFR 60 Subpart Ka – Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After May 18, 1978, and Prior to July 23, 1984 Similar to NSPS Subpart K, NSPS Subpart Ka is applicable to petroleum storage tanks which were constructed, reconstructed, or modified between May 1978 and July 1984, and which have a storage capacity greater than 40,000 gallons.15 As previously discussed, the proposed aboveground diesel storage tanks are new units constructed after 1984. Further, none of the diesel tanks would have a storage capacity greater than 40,000 gallons. Therefore, NSPS Subpart Ka is also not applicable. 4.3.4 40 CFR 60 Subpart Kb – Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984 NSPS Subpart Kb applies to volatile organic liquid (VOL) storage vessels which were constructed, reconstructed, or modified after July 1984. VOL storage tanks are only subject to this rule if they meet one of the following criteria:16 14 40 CFR 60.110 15 40 CFR 60.110a 16 40 CFR 60.110b(b) Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 8 Ramboll Confidential • The storage vessel has a maximum storage capacity greater than or equal to 151 m3 (39,890 gallons) and which stores a VOL with a maximum true vapor pressure exceeding 3.5 kPa (0.51 psia); or • The storage vessel has a maximum storage capacity greater than or equal to 75 m3 (19,812.9 gallons) but less than 151 m3 and which stores a VOL with a maximum true vapor pressure exceeding 15.0 kPa (2.2 psia). The new fuel storage tanks would all have a storage capacity less than 19,812.9 gallons, therefore, NSPS Subpart Kb does not apply. 4.3.5 40 CFR 60 Subpart IIII – Stationary Compression Ignition Internal Combustion Engines NSPS Subpart IIII applies to new, modified, and reconstructed compression ignition (CI) internal combustion engines (ICE). New engines are subject to this regulation if construction of the CI ICE commenced after July 11, 2005, and if the engine was manufactured after April 1, 2006, for CI ICE that are not fire pump engines, or July 1, 2006, for CI ICE that are fire pump engines.17 This rule is applicable to the proposed CI ICE that would be operated at the facility. The proposed generator would meet the definition of emergency stationary ICE in 40 CFR 60.4219 and would not operate as a fire pump engine. 4.3.5.1 Emission Standards The proposed generators would be classified as emergency generators under this regulation and would each have a displacement of less than 10 liters per cylinder. Per 40 CFR 60.4205(b), the generators would be subject to the applicable emission standards in 40 CFR 89.112-113. The Tier 2 emission standards for nonroad engines with a rated power greater than 560 kW are summarized in Table 2.18 The USEPA Tier 2 standards for nonroad engines are based on a weighted cycle and cannot be used for comparison to the actual emissions from the engine at a specific load. Table 2. Tier 2 Emission Standards1 Pollutant Emission Standard (g/kW-hr) NOX + Non-Methane Hydrocarbons (NMHC) 6.4 CO 3.5 PM 0.20 Notes: 1) Obtained from 40 CFR 89.112 (a), Table 1 for Tier 2 engines rated >560 kW. 17 40 CFR 60.4200(a)(2) 18 40 CFR 89.112(a), Table 1. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 9 Ramboll Confidential Additionally, the facility is required to only combust in its generators fuel that complies with the following requirements in 40 CFR 80.510(b) for nonroad diesel fuel:19 • Maximum sulfur content of 15 ppm; and • Either a minimum cetane index of 40 or a maximum aromatic content of 35 volume percent. The applicant would comply with the emission standards in 40 CFR 89.112-113 by purchasing engines certified by the manufacturer to comply with the Tier 2 emission standards.20 Further, the site would operate and maintain the engine according to the manufacturer’s emission-related written instructions and only change those emission-related settings that are permitted by the manufacturer.21 4.3.5.2 Run Time Restrictions for Emergency ICE In order for a stationary engine to be considered an emergency ICE under NSPS Subpart IIII, it must meet the run time restrictions in 40 CFR 60.4211(f). There is no restriction on usage of an emergency ICE in emergency situations.22 Each engine is restricted to a maximum of 100 hours per calendar year of operation for maintenance checks and readiness testing.23 Each engine is allowed up to 50 hours per calendar year of non-emergency operation other than maintenance and testing; however, any non-emergency run time must be counted as part of the 100 hours per calendar year for maintenance and testing.24 Any other operations are prohibited. The facility would equip each emergency ICE with a non-resettable hour meter prior to startup of the unit in order to verify compliance with the run time restrictions for emergency and non-emergency runs.25 4.3.5.3 Notifications, Reporting, and Recordkeeping An Initial Notification under NSPS Subpart A is not required for emergency stationary ICE. The facility would retain records of the emergency and non-emergency runs for the engine for a minimum of two years, as recorded through the engine’s non-resettable hour meter. The records would indicate the time of operation of the engine and the reason the engine was in operation during that time.26 4.3.6 40 CFR 60 Subpart JJJJ – Stationary Spark Ignition Internal Combustion Engines NSPS Subpart JJJJ is applicable to new, modified, and reconstructed stationary spark ignition (SI) ICE. The proposed generator would be categorized as a CI ICE. As such, NSPS Subpart JJJJ does not apply. 19 40 CFR 60.4207(b) 20 40 CFR 60.4211(c) 21 40 CFR 60.4211(a) 22 40 CFR 60.4211(f)(1) 23 40 CFR 60.4211(f)(2)(i).

A facility that has potential emissions exceeding 10 tpy for any individual HAP and/or emissions exceeding 25 tpy for the sum of all HAP is classified as a major source of HAP emissions. A facility that is not a major source of HAP is classified as an area source. The facility would continue to be classified as an area source with the proposed modifications because it has potential HAP emissions less than the major source thresholds. The following sections discuss the potentially applicable NESHAP standards for the proposed generator and storage tanks. 4.4.1 40 CFR 63 Subpart A – General Provisions NESHAP Subpart A provides generally applicable requirements for testing, monitoring, notifications, and recordkeeping. Any source that is subject to another subpart under 40 CFR 63 is also subject to Subpart A, unless otherwise stated in the specific subpart. 4.4.2 40 CFR 63 Subpart EEEE – Organic Liquids Distribution (Non-Gasoline) NESHAP Subpart EEEE is applicable to organic liquids distribution operations, including organic liquid storage tanks, located at major sources of HAP emissions.27 This regulation does not apply as the facility would continue to be classified as an area source of HAP emissions. 4.4.3 40 CFR 63 Subpart ZZZZ – Stationary Reciprocating Internal Combustion Engines NESHAP Subpart ZZZZ applies to new and existing stationary reciprocating internal combustion engines (RICE) located at both major and area sources of HAP emissions. Per 40 CFR 63.6590(c), for new or reconstructed stationary RICE located at an area source of HAP emissions, the only requirement under NESHAP Subpart ZZZZ is to meet the requirements of NSPS Subpart IIII for CI ICE and of NSPS Subpart JJJJ for SI ICE. Since the proposed CI ICE at the facility would be in compliance with NSPS Subpart IIII, the unit would also be in compliance with NESHAP Subpart ZZZZ. No further requirements apply for this engine under this regulation. 4.5 Chemical Accident Prevention Provisions The Chemical Accident Prevention Provisions, promulgated in 40 CFR 68, provide requirements for the development of risk management prevention (RMP) plans for regulated substances. Applicability to RMP plan requirements is based on the types and amounts of chemicals stored at a facility. Neither gasoline or diesel fuel is on the list of regulated substances in Subpart F of this rule; therefore, the facility is not required to develop an RMP plan under 40 CFR 68. 4.6 Utah Administrative Code, Title R307 – Environmental Quality, Air Quality In addition to the federal regulations, Title R307 of the UAC establishes regulations applicable at the emission unit level and at the facility level. The state regulations in Chapter 2 also include general requirements for facilities, such as the requirement to obtain permits to construct and operate. Source-specific standards in R307 that are potentially applicable to the proposed generator are discussed in the following sections. 27 40 CFR 63.2330 Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 11 Ramboll Confidential 4.6.1 R307-203 – Emission Standards: Sulfur Content of Fuels This regulation provides emission standards for fuel burning equipment that combusts coal, oil, or a mixture thereof. The rule does not apply to sources covered by a NSPS for sulfur emissions. While the NSPS that regulates the emergency generator engines, 40 CFR 60 Subpart IIII, does not specifically regulate sulfur emissions, it does provide a requirement for the fuel sulfur content of the diesel fuel combusted in the engines (maximum sulfur content of 0.0015% by weight). The NSPS Subpart IIII fuel sulfur content limit is more stringent than that contained in this regulation (i.e., 0.85 pounds per million British thermal unit [lb/MMBtu]). Therefore, the NSPS Subpart IIII fuel sulfur content limitation applies in lieu of the R307-203 limitation. 4.6.2 R307-305-3 – Nonattainment and Maintenance Areas for PM10: Emission Standards – Visible Emissions This rule sets standards for visible emissions in PM10 nonattainment and maintenance areas, including Salt Lake County. R307-305-3(3) states that visible emissions from diesel engines in stationary operation shall be of a shade or density no darker than 20% opacity, not exceeding three minutes in any hour.28 The proposed emergency generators would be subject to this standard. R307-305-3(4) further clarifies that visible emissions exceeding the opacity standards for short time periods as the result of initial warm-up, caused by start-up or shutdown of a facility, installation or operation, or unavoidable combustion irregularities which do not exceed three minutes in length shall not be deemed in violation, provided that UDAQ finds that adequate control technology has been applied. The applicant would be required to minimize visible and non-visible emissions during start-up or shutdown, installation, or operation through the use of adequate control technology and proper procedures. Such requirements would be satisfied through exclusive use of ultra-low sulfur diesel fuel in all generator engines onsite consistent with NSPS Subpart IIII requirements. 4.6.3 R307-309 – Nonattainment and Maintenance Areas for PM10 and PM2.5: Fugitive Emissions and Fugitive Dust This rule sets standards for control of fugitive dust and fugitive emissions in PM10 and PM2.5 nonattainment and maintenance areas, including Salt Lake County. R307-309-4 states that fugitive emissions from any source shall not exceed 15% opacity. During operation, the proposed facility would not be a source of fugitive dust since it would not have unpaved roads in operational areas and would not engage in the handling of dust generating bulk materials. 4.6.4 R307-401 – Permits: New and Modified Sources R307-401 establishes application and permitting requirements for new installations and modifications to existing installations throughout the State of Utah. As a minor source for all criteria pollutants (and associated precursor pollutants) located in a nonattainment area, the facility is categorically subject to the provisions of R307-401. The applicant would continue to comply with all generally applicable requirements found under R307-401 as evidenced in the supporting sections of this NOI application. Additional provisions that apply to modifications to existing installations located in nonattainment areas are found under R307- 403, discussed subsequently. 28 Unavoidable combustion irregularities which exceed three minutes in length must be handled in accordance with R307-107. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 12 Ramboll Confidential 4.6.5 R307-403 – Permits: New and Modified Sources in Nonattainment Areas and Maintenance Areas R307-403 implements the provisions of the federal nonattainment area permitting program for major sources as required by 40 CFR 51.165. The requirements under R307-403-5(1) apply to new or modified sources located in a PM10 nonattainment area that have the potential to emit more than 25 tpy of combined PM10, SO2, and NOX emissions. Salt Lake County is currently designated as attainment for PM10, so R307-403-5(1) is not applicable. Per R307-403-5(2), major sources or major modifications to existing sources located in a PM2.5 nonattainment areas must obtain ERCs. As demonstrated in Table 1, the proposed modifications would not cause the facility to be classified as a major source and the project itself would not meet the definition of a major modification to existing sources. Therefore, the requirement to obtain ERCs prior to initiating construction does not apply. 4.6.6 R307-410 – Emissions Impact Analysis The provisions of R307-410 establish the procedures and requirements for evaluating the emissions impact of new and modified sources that require an approval order under R307- 401 to ensure that the source would not interfere with the attainment or maintenance of any NAAQS in the state of Utah. The facility’s potential emissions with the newly proposed generators would not exceed any of the modeling thresholds under R307-410-4 Table 1. However, SLCDA understands that UDEQ would like the applicant to demonstrate compliance with the 1-hour NO2 NAAQS since the proposed facility modification’s NOx emissions will exceed 10 pounds per hour. SLCDA has conducted an air dispersion modeling analysis using USEPA’s recommended short-range transport dispersion model (i.e., AERMOD). This analysis was conducted in accordance with the air dispersion modeling protocol submitted to UDAQ on June 14, 2023.29 The facility’s demonstration of compliance with the 1-hour NO2 and annual NAAQS is shown in the final modeling report, provided to UDAQ under separate cover, and is summarized in Section 6. 4.6.7 R307-420 – Permits: Ozone Offset Requirements in Davis and Salt Lake County Counties Section R307-420-1 indicates that this regulation becomes effective only when Salt Lake and Utah counties are redesignated into attainment for ozone. Additionally, this regulation only applies to major sources or major modifications as defined in R307-420-2. Since the facility is not a major source and this project is not considered a major modification, the facility is not subject to this regulation. 4.6.8 R307-421 – Permits: PM10 Offset Requirements in Salt Lake County and Utah County Section R307-421-5 indicates that this regulation becomes effective only when Salt Lake and Utah counties are redesignated into attainment for PM10. Salt Lake County was redesignated as attainment for PM10 on March 27, 2020, and so this regulation is applicable. The combined emissions increase of PM10, SO2, and NOX attributable to the proposed generators at the facility is less than the 25 tpy threshold; therefore, the requirement to obtain ERCs prior to initiating construction does not apply. 29 The Modeling Protocol was approved by Dave Prey on January 4, 2022. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Evaluation of Best Available Control Technology 13 Ramboll Confidential 5. EVALUATION OF BEST AVAILABLE CONTROL TECHNOLOGY New and modified sources of air emissions in Utah are required to implement best available control technology (BACT) for control of emissions when applying for an AO.30 Determination of BACT includes analyses pertaining to technical feasibility of potential air pollution control technologies, as well as factors such as the energy, environmental, and economic impacts of the technology. This section evaluates BACT for emissions of criteria pollutants from the emergency generators, specifically NOX, CO, VOC, PM10, PM2.5, and SO2. The emergency backup generator to be installed at the facility would be certified by the manufacturer to meet the requirements of USEPA’s Tier 2 emission standards, in accordance with the requirements of 40 CFR 60 Subpart IIII. The primary pollutant of concern is NOX, as indicated by the potential emissions of the emergency backup generators and local attainment considerations (i.e., NOX is a precursor pollutant for secondary formation of ozone, PM10, and PM2.5). Because the emergency backup generator would operate in standby mode the majority of the time, the use of engines certified by the manufacturer to meet the Tier 2 standards satisfies BACT requirements for this scenario. However, to be proactive, the applicant has evaluated additional potential control technologies that can reduce NOX emissions. 5.1 BACT Determination for NOX In accordance with the USEPA’s top-down approach for conducting BACT analyses, the applicant has reviewed potential control technologies for reducing NOX emissions from diesel- fired ICE. Of all potential technologies, those technically capable of reducing NOX emissions from diesel-fired ICE of equivalent capacity to those used at the facility include the use of (1) Selective Catalytic Reduction (SCR), (2) engines certified by the manufacturer to the USEPA’s Tier 4 emissions standards under 40 CFR 60 Subpart IIII, and (3) engines certified by the manufacturer to the USEPA’s Tier 2 emission standards under 40 CFR 60 Subpart IIII. The following sections evaluate these potential NOX control technologies for determination of BACT. 5.1.1 Evaluation of SCR SCR achieves a reduction in NOX emissions by passing a stream of urea solution into the generator exhaust, in the presence of a fixed, solid catalyst. The urea reacts with the NOX yielding nitrogen, water, and CO2. The applicant has evaluated the control effectiveness and potential energy, environmental, and economic impacts in the following subsections. SCR Control Effectiveness The control efficiency of this technology is dependent on several factors including generator load, catalyst state, and exhaust temperature. The SCR controls evaluated are estimated to achieve up to a 90% reduction in NOX emissions 31, which would equate to a NOX emissions rate of 0.44 g/bhp-hr (1.94 lb/hr/generator) for the Cummins generator. To ensure the SCR systems operate effectively, the unit must be operated and maintained in accordance with the manufacturer’s recommendations. However, per the California Air Resources Board’s 30 R307-401-5(d) 31 Based on the maximum control efficiency from USEPA’s Air Pollution Control Technology Fact Sheet, Selective Catalytic Reduction (SCR), USEPA-452/F-03-032. https://www3.epa.gov/ttn/catc/cica/files/fscr.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential (ARB) review on stationary compression ignition engines, it is stated that since SCR’s require exhaust temperatures of 260°C to 540°C (500°F-1,004°F), it may be difficult for emergency generators to meet these temperatures since most of their operations are on low loads and for short periods of time 32. Therefore, if the exhaust temperature was not met for these runs, the SCR would not activate, and the desired NOX reduction would not be met. Additionally, an increase in load size or run duration for the activation of the SCR would result in additional emissions from the engine. Evaluation of Energy Impacts of SCR The energy required to operate SCR after-treatment is minimal relative to that of a generator. During the winter months, there would be a small input of energy into the SCR unit to prevent freezing of the urea solution. Evaluation of Environmental Impacts of SCR During operation of the SCR unit, the reaction of NOX, urea, and oxygen would result in the formation of CO2 emissions to the atmosphere, in addition to the formation of nitrogen and water vapor emissions. However, the amount of CO2 emissions from urea usage is a minor contributor to the overall GHG emissions from the engine resulting from diesel combustion, and the environmental impact of the additional CO2 emissions is more than offset by the benefit of NOX reduction. Additionally, the SCR process requires the installation of reagent storage facilities, a system capable of metering and diluting the stock reagent into the appropriate solution, and an atomization/injection system at the appropriate locations in the combustion unit. Evaluation of Economic Impacts of SCR The economic impact of installing SCR technology is significant. The procurement and installation process would consume a large amount of capital, and there would also be long- term costs associated with the maintenance, repair, consumables, and catalyst storage and regeneration associated with operating the SCR units. California’s ARB also researched the cost associated with installing diesel particulate filters (DPF) and SCRs on new Tier 2 or Tier 3 engines 33. The following costs were determined based on engine size and SLCDA has conservatively assumed that the cost for SCR installation, without DPF, is equal to the difference in cost between the DPF and DPF/SCR scenario, as shown in Table 3 below. 32 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf 33 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential Table 3. SCR Cost Analysis HP Range Cost of New Tier 2/3 Gen- Set ($) Scenario 1 – DPF Only Additional Costs Scenario 2 – DPF and SCR Additional Costs SLCDA Estimate – SCR Only Additional Costs 50-174 $29,000 $4,000 $13,000 $9,000 175-749 $67,000 $18,000 $55,000 $37,000 750-1209 $141,000 $37,000 $115,000 $78,000 1207-2000 $309,000 $61,000 $189,000 $128,000 >2,000 $523,000 $100,000 $310,000 $210,000 Note: These numbers have not been updated to reflect 2023 $ amount and would increase if current costs were added to the analysis. According to CARB data, SCR would result in an additional $210,000 each for the new 1,500 kW (2,012 hp) engines. This would result in ~$145,000/ton NOX removed. Additionally, this does not account for the ongoing operation and maintenance costs of the SCR system. 5.1.2 Evaluation of USEPA Tier 4 Certification 40 CFR 60 Subpart IIII requires owners and operators of new non-emergency diesel-fired ICE with a rated power output of greater than 560 kW to purchase engines that are certified by the manufacturer to the USEPA’s Tier 4 nonroad engine emission standards. As such, the proposed diesel-fired emergency backup generator to be installed at the site is not subject to Tier 4 certification. However, for completeness, the applicant has reviewed the potential use of Tier 4-certified engines at the site as a means of demonstrating BACT-level NOX emissions. For the purposes of evaluating potential NOX emissions control technologies, the applicant considers the use of Tier 4-certified engines to be effectively equivalent from an emissions performance perspective to the use of Tier 2-certified engines utilizing SCR for NOX emissions control. According to the California ARB, a Tier 4 engine supplied by a manufacturer with a DPF and SCR would be an additional $310,000 for each of the new 1,500 kW engines.34 5.1.3 Evaluation of USEPA Tier 2 Certification 40 CFR 60 Subpart IIII requires owners and operators of new emergency diesel-fired ICE to purchase engines certified by the manufacturer to the USEPA’s nonroad engine emission standards. Since the use of Tier 2-certified engines does not involve an exhaust stream control technique, there are no associated adverse environmental, energy, or economic impacts. 34 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential 5.1.4 Selection of BACT for NOX Based on a limited review of USEPA’s RACT/BACT/LAER Clearinghouse (RBLC) database for diesel generators, the use of either Tier 4 engines or Tier 2 engines with SCR represents the lowest achievable emission rate (LAER) level of emission control for emergency backup generators and exceeds the BACT requirements of this minor source project. In reviewing the control techniques described above, SLCDA has determined that the Tier 2 engines meet BACT for NOX by implementing good operating practices and through purchasing an engine certified to the required Tier 2 emissions standards. Although the Tier 4 engine and Tier 2 engines with SCR are technically feasible, due to the low potential emission reduction for the generators and the high capital and annual operating costs, these options were determined to be economically infeasible. 5.2 BACT Determination for Other Criteria Pollutants Emissions of all other criteria pollutants would be less than 1 tpy for each emergency generator. Due to the low emission rates of these pollutants, they do not warrant control technology beyond those inherent to Tier 2 generators, which is considered BACT for this facility. This conclusion is consistent with the USEPA’s determination in the development of 40 CFR 60 Subpart IIII that add-on controls are not economically viable for emergency ICE. While the use of Tier 4-certified engines could potentially lower emissions of PM, the conservatively estimated potential generator emissions of PM are already minimal (0.04 tpy versus a major source threshold of 70 tpy) and are based on the maximum ratio of the manufacturer’s “Not to Exceed” emission factor, which is approximately 25% higher than the manufacturer’s “nominal” or expected emission factors. As such, the use of and significant costs associated with installing a Tier 4-certified engine would be expected to result in only minimal reductions of PM emissions (e.g., less than 0.5 tpy) at the site. Consequently, the applicant considers the use of Tier 2-certified engines to represent BACT for all other criteria pollutants. The proposed generators are certified by the manufacturer to the USEPA’s Tier 2 emissions standards, and the site will operate and maintain each engine according to the manufacturer’s emission-related written instructions and only change those emission-related settings that are permitted by the manufacturer. Further, the applicant will only combust ultra-low sulfur diesel fuel in its generators, with a maximum fuel sulfur content of 0.0015% by weight consistent with the requirements of NSPS Subpart IIII. 5.3 Conclusion The emergency generator engines to be installed at the facility are certified by the manufacturer to meet the requirements of USEPA’s Tier 2 emission standards, in accordance with the requirements of 40 CFR 60 Subpart IIII. The primary pollutant of concern from this generator is NOX, as indicated by the potential emissions and local attainment considerations as a precursor for ozone, PM10, and PM2.5. Because this emergency generator would be in standby mode the majority of the time and typically run for short periods of time, the use of engines certified by the manufacturer to meet the Tier 2 standards satisfies BACT requirements for this scenario.

Emission factors were obtained from the manufacturer's specification sheets. Where available, engine performance data were used to identify power output at the most conservative engine load. Particulate matter emissions were conservatively assumed to be equal to PM2.5 emissions. Where applicable, individual emission factors for NOx and NMHC were determined using a NOx/NMHC ratio of 95% to 5% for diesel engines, per U.S. EPA federal emission standards referenced in Texas Commission on Environmental Quality's Emissions Reductions Plan. SOx emission factors for engines < 600 HP were obtained from US EPA's AP-42 Chapter 3.3, Table 3.3-1. All SOx emissions were conservatively assumed to be equivalent to SO2 emissions.

INTRODUCTION Salt Lake City Department of Airports (“SLCDA” or “the applicant”) is submitting this Notice of Intent (NOI) to the Utah Department of Environmental Quality – Division of Air Quality (UDAQ) to request authority to install one (1) new 450 kW emergency generator, two (2) new 1,500 kW emergency generators, and three (3) new 8,000-gallon aboveground fuel storage tanks (ASTs). The applicant is also proposing to relocate an existing 300 kW generator and to update the reported capacity of another existing generator from 400 kW to 375 kW. In addition, the applicant intends to remove two (2) emergency generators: one (1) 400 kW unit, and one (1) 350 kW unit. Finally, the applicant wishes to remove the training burn pit, which has been unused since 2017, from the permit, due to discontinued service. SLCDA currently operates under Approval Order (AO) DAQE-AN104500029-22, which was approved on November 2, 2022. A site location map is provided in Appendix A. The facility is currently classified as a synthetic minor source of air emissions with respect to the Title V and New Source Review (NSR) permitting programs. Since potential facility-wide emissions of nitrogen oxides (NOX), carbon monoxide (CO), and particulate matter (PM) would each exceed 5 tons per year (tpy), the applicant is hereby requesting an Approval Order (AO) from UDAQ for construction and operation of the proposed modifications at the facility, in accordance with the requirements of the Utah Administrative Code (UAC) Rule R307-401-8.1 The NOI application forms are included in Appendix B of this report. 1 Utah Administrative Code.

FACILITY DESCRIPTION The applicant is proposing to construct and operate two (2) additional diesel-fired emergency generators for the Airport Redevelopment Project (ARP). In addition, SLCDA is requesting to add one (1) new generator, remove two (2) generators, update the reported capacity of one (1) generator, relocate one (1) generator, and add three (3) above-ground storage tanks (ASTs). Lastly, SLCDA intends to remove the training burn pit from the permit, which has been out of operation since 2017. A list of the proposed modifications is provided below,2 and the manufacturer’s specification sheets for the proposed new generators are provided in Appendix C. Equipment Additions: • One (1) 450 kW emergency generator at Pump Station #5 • Two (2) 1,500 kW emergency generators as part of ARP effort • Three (3) 8,000-gallon above-ground fuel storage tanks (ASTs) at North Support Source Location/Generator Rating Administrative Updates: • II.A.17 300 kW generator at Pump Station #5 – Relocation to North Support • II.A.38 400 kW generator at Airport Training Facility – Update reported capacity from 400 kW to 375 kW • II.A.19 350 kW and II.A.20 375 kW emergency generators at North Support – Removal of both sources. • II.A.44 Training Equipment at burn pit – Removal of source Other sources of emissions at the facility consist of emergency generators, diesel and gasoline storage tanks, two paint booths, a natural gas-fired heat exchanger (8 MMBtu/hr), four boilers rated at 25 MMBtu/hr, and various natural gas-fired boilers and comfort heating devices rated at less than 5 MMBtu/hr. As the mentioned sources would not be modified, they are not part of this application. 2 Permit condition numbers coincide with conditions in Approval Order (AO) DAQE-AN104500028-21 Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Emissions Calculations 3 Ramboll Confidential 3. EMISSIONS CALCULATIONS Pollutants emitted from the facility include NOX; CO; VOCs; sulfur dioxide (SO2); particulate matter (PM); PM less than 10 microns in diameter (PM10); PM less than 2.5 microns in diameter (PM2.5); hazardous air pollutants (HAPs); and greenhouse gases, represented in terms of carbon dioxide equivalents (CO2e). The methodology used to estimate potential emissions is discussed in the following sections. The manufacturer’s specification sheets for the generator are provided in Appendix C, and detailed calculations are provided for the proposed generators in Appendix D. 3.1 New Diesel-Fired Emergency Standby Generators Operation of the diesel-fired emergency generator engines would result in emissions of products of combustion. The derivation of potential hourly and annual emissions is presented below. 3.1.1 Derivation of Potential Hourly Emissions The following emission factors were used to estimate the potential hourly emissions from the emergency generators: • The manufacturer’s engine-specific emission factors for NOX, VOC (hydrocarbons), CO, and filterable PM were used to estimate the emissions of those pollutants at each generator load. If engine-specific emission factors were not available, emission factors from AP-42 Chapter 3.3 Gasoline And Diesel Industrial Engines and Chapter 3.4, Large Stationary Diesel and All Stationary Dual-fuel Engines were conservatively used.3,4 It was conservatively assumed that all particulate matter in the engine exhaust is PM2.5. Individual emission factors for NOx and Non- methane hydrocarbons (NMHC) were determined using a NOx/NMHC ratio of 95% to 5%, per USEPA’s federal emission standards referenced in TCEQ’s Emissions Reductions Plan.5 Conversion from NMHC to VOC emissions are based on guidance from USEPA’s conversion factors for hydrocarbon emission components.6 Potential hourly emissions were based on the maximum hourly emission rate for each pollutant at any engine load for each engine group. • Emissions of SO2, CO2, and HAPs were estimated based on the diesel fuel emission factors in the USEPA’s AP-42, Chapter 3.4, Large Stationary Diesel and All Stationary Dual-fuel Engines. The emission factor for SO2 was calculated based on the maximum allowable diesel fuel sulfur content of 0.0015% by weight, per 40 CFR 60 Subpart IIII (see Section 0 of this report). The emissions calculations assumed a diesel high heating value of 0.137 MMBtu/gal, based on AP- 42, Table 3.4-1, footnote a.7 3 US EPA. 1996.

Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 6 Ramboll Confidential 4. FEDERAL AND STATE REGULATORY APPLICABILITY The following sections outline the federal and state air regulations that are potentially applicable to the facility. Specifically, requirements under the federal NSR permitting program, Title V of the Clean Air Act Amendments, New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutants (NESHAP), Chemical Accident Prevention Provisions, and the UAC are discussed herein. 4.1 New Source Review The federal NSR permitting program regulates emissions from major stationary sources of regulated air pollutants. NSR is comprised of two elements: Nonattainment NSR (NNSR) and Prevention of Significant Deterioration (PSD). NNSR permitting is applicable in areas that have been designated as nonattainment for a regulated pollutant under the National Ambient Air Quality Standards (NAAQS). PSD permitting applies in areas that have been designated as attainment or unclassifiable. The facility is located in Salt Lake County, which has been designated as serious nonattainment for PM2.5,8 moderate nonattainment for ozone, and as attainment or unclassifiable for all other criteria pollutants.9,10 As such, NNSR is the potentially applicable program for ground-level ozone formation (VOCs and NOX), PM2.5, and precursors for the formation of PM2.5, which include NOX, SO2, and VOC. PSD is the applicable permitting program for all other criteria pollutants at the facility. The NSR major source threshold for Salt Lake County is 70 tpy for PM2.5 and each of its precursor pollutants (NOX, SO2, and VOC).11,12 Additionally, pursuant to UAC R307-420, the Major Source threshold for VOC is 50 tpy in Salt Lake County. Although UAC R307-420 is only applicable when Salt Lake County is classified as in attainment for ozone, SLCDA has conservatively assumed the Major Source threshold for VOC is 50 tpy. As shown in Table 1, the potential emissions from operations at the facility for each of these pollutants would be less than the applicable major source thresholds. The facility is also classified as a minor source with respect to PSD, and the facility-wide potential emissions for all NSR-regulated criteria pollutants would be less than the major source threshold of 100 tpy, pursuant UAC R307-101-2.13 4.2 Title V Operating Permits The Title V operating permits program, promulgated in 40 CFR 70, requires a facility to obtain a Title V operating permit if it has potential emissions of a regulated criteria pollutant exceeding 100 tpy, of any single HAP exceeding 10 tpy, or of the aggregate of all HAPs exceeding 25 tpy. However, as discussed in Section 4.1, the Title V major source thresholds for PM2.5 and its precursor pollutants are at a lower threshold of 70 tpy in Salt Lake County since the area is designated as serious non-attainment for PM2.5. Additionally, pursuant to 8 UDAQ submitted a PM2.5 Maintenance Plan based on a Clean Data Determination and, as such, the redesignation to a maintenance area is pending. 9 40 CFR 81.345 10 Salt Lake County was redesignated to a maintenance area for PM10 on March 27, 2020. 11 Utah Administrative Code.

Although UAC R307-420 is only applicable when Salt Lake County is classified as in attainment for ozone, SLCDA has conservatively assumed the Major Source threshold for VOC is 50 tpy. Facility-wide potential emissions would be less than 100 tpy each for all criteria pollutants, less than 70 tpy each for PM2.5 and its precursors, less than 50 tpy for VOC, and less than the applicable major source thresholds for HAPs. As such, the facility would continue to be classified as a synthetic minor source of air emissions with respect to the Title V program. 4.3 New Source Performance Standards NSPS, promulgated in 40 CFR 60, provide emissions standards for criteria pollutant emissions from new, modified, and reconstructed sources. The following sections discuss the NSPS that are potentially applicable to the proposed generators and fuel storage tanks. 4.3.1 40 CFR 60 Subpart A – General Provisions NSPS Subpart A provides generally applicable requirements for testing, monitoring, notifications, and recordkeeping. Any source that is subject to another subpart under 40 CFR 60 is also subject to Subpart A, unless otherwise stated in the specific subpart. 4.3.2 40 CFR 60 Subpart K – Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After June 11, 1973, and Prior to May 19, 1978 NSPS Subpart K is applicable to petroleum storage tanks which were constructed, reconstructed, or modified between June 1973 and May 1978, and which have a storage capacity greater than 40,000 gallons.14 The facility would maintain aboveground fuel storage tanks for the proposed generators; however, each of these tanks are new units constructed after 1978. Furthermore, none of the tanks would have a storage capacity greater than 40,000 gallons. Therefore, NSPS Subpart K provisions do not apply. 4.3.3 40 CFR 60 Subpart Ka – Storage Vessels for Petroleum Liquids for Which Construction, Reconstruction, or Modification Commenced After May 18, 1978, and Prior to July 23, 1984 Similar to NSPS Subpart K, NSPS Subpart Ka is applicable to petroleum storage tanks which were constructed, reconstructed, or modified between May 1978 and July 1984, and which have a storage capacity greater than 40,000 gallons.15 As previously discussed, the proposed aboveground diesel storage tanks are new units constructed after 1984. Further, none of the diesel tanks would have a storage capacity greater than 40,000 gallons. Therefore, NSPS Subpart Ka is also not applicable. 4.3.4 40 CFR 60 Subpart Kb – Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984 NSPS Subpart Kb applies to volatile organic liquid (VOL) storage vessels which were constructed, reconstructed, or modified after July 1984. VOL storage tanks are only subject to this rule if they meet one of the following criteria:16 14 40 CFR 60.110 15 40 CFR 60.110a 16 40 CFR 60.110b(b) Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 8 Ramboll Confidential • The storage vessel has a maximum storage capacity greater than or equal to 151 m3 (39,890 gallons) and which stores a VOL with a maximum true vapor pressure exceeding 3.5 kPa (0.51 psia); or • The storage vessel has a maximum storage capacity greater than or equal to 75 m3 (19,812.9 gallons) but less than 151 m3 and which stores a VOL with a maximum true vapor pressure exceeding 15.0 kPa (2.2 psia). The new fuel storage tanks would all have a storage capacity less than 19,812.9 gallons, therefore, NSPS Subpart Kb does not apply. 4.3.5 40 CFR 60 Subpart IIII – Stationary Compression Ignition Internal Combustion Engines NSPS Subpart IIII applies to new, modified, and reconstructed compression ignition (CI) internal combustion engines (ICE). New engines are subject to this regulation if construction of the CI ICE commenced after July 11, 2005, and if the engine was manufactured after April 1, 2006, for CI ICE that are not fire pump engines, or July 1, 2006, for CI ICE that are fire pump engines.17 This rule is applicable to the proposed CI ICE that would be operated at the facility. The proposed generator would meet the definition of emergency stationary ICE in 40 CFR 60.4219 and would not operate as a fire pump engine. 4.3.5.1 Emission Standards The proposed generators would be classified as emergency generators under this regulation and would each have a displacement of less than 10 liters per cylinder. Per 40 CFR 60.4205(b), the generators would be subject to the applicable emission standards in 40 CFR 89.112-113. The Tier 2 emission standards for nonroad engines with a rated power greater than 560 kW are summarized in Table 2.18 The USEPA Tier 2 standards for nonroad engines are based on a weighted cycle and cannot be used for comparison to the actual emissions from the engine at a specific load.

Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 9 Ramboll Confidential Additionally, the facility is required to only combust in its generators fuel that complies with the following requirements in 40 CFR 80.510(b) for nonroad diesel fuel:19 • Maximum sulfur content of 15 ppm; and • Either a minimum cetane index of 40 or a maximum aromatic content of 35 volume percent. The applicant would comply with the emission standards in 40 CFR 89.112-113 by purchasing engines certified by the manufacturer to comply with the Tier 2 emission standards.20 Further, the site would operate and maintain the engine according to the manufacturer’s emission-related written instructions and only change those emission-related settings that are permitted by the manufacturer.21 4.3.5.2 Run Time Restrictions for Emergency ICE In order for a stationary engine to be considered an emergency ICE under NSPS Subpart IIII, it must meet the run time restrictions in 40 CFR 60.4211(f). There is no restriction on usage of an emergency ICE in emergency situations.22 Each engine is restricted to a maximum of 100 hours per calendar year of operation for maintenance checks and readiness testing.23 Each engine is allowed up to 50 hours per calendar year of non-emergency operation other than maintenance and testing; however, any non-emergency run time must be counted as part of the 100 hours per calendar year for maintenance and testing.24 Any other operations are prohibited. The facility would equip each emergency ICE with a non-resettable hour meter prior to startup of the unit in order to verify compliance with the run time restrictions for emergency and non-emergency runs.25 4.3.5.3 Notifications, Reporting, and Recordkeeping An Initial Notification under NSPS Subpart A is not required for emergency stationary ICE. The facility would retain records of the emergency and non-emergency runs for the engine for a minimum of two years, as recorded through the engine’s non-resettable hour meter. The records would indicate the time of operation of the engine and the reason the engine was in operation during that time.26 4.3.6 40 CFR 60 Subpart JJJJ – Stationary Spark Ignition Internal Combustion Engines NSPS Subpart JJJJ is applicable to new, modified, and reconstructed stationary spark ignition (SI) ICE. The proposed generator would be categorized as a CI ICE. As such, NSPS Subpart JJJJ does not apply. 19 40 CFR 60.4207(b) 20 40 CFR 60.4211(c) 21 40 CFR 60.4211(a) 22 40 CFR 60.4211(f)(1) 23 40 CFR 60.4211(f)(2)(i).

A facility that has potential emissions exceeding 10 tpy for any individual HAP and/or emissions exceeding 25 tpy for the sum of all HAP is classified as a major source of HAP emissions. A facility that is not a major source of HAP is classified as an area source. The facility would continue to be classified as an area source with the proposed modifications because it has potential HAP emissions less than the major source thresholds. The following sections discuss the potentially applicable NESHAP standards for the proposed generator and storage tanks. 4.4.1 40 CFR 63 Subpart A – General Provisions NESHAP Subpart A provides generally applicable requirements for testing, monitoring, notifications, and recordkeeping. Any source that is subject to another subpart under 40 CFR 63 is also subject to Subpart A, unless otherwise stated in the specific subpart. 4.4.2 40 CFR 63 Subpart EEEE – Organic Liquids Distribution (Non-Gasoline) NESHAP Subpart EEEE is applicable to organic liquids distribution operations, including organic liquid storage tanks, located at major sources of HAP emissions.27 This regulation does not apply as the facility would continue to be classified as an area source of HAP emissions. 4.4.3 40 CFR 63 Subpart ZZZZ – Stationary Reciprocating Internal Combustion Engines NESHAP Subpart ZZZZ applies to new and existing stationary reciprocating internal combustion engines (RICE) located at both major and area sources of HAP emissions. Per 40 CFR 63.6590(c), for new or reconstructed stationary RICE located at an area source of HAP emissions, the only requirement under NESHAP Subpart ZZZZ is to meet the requirements of NSPS Subpart IIII for CI ICE and of NSPS Subpart JJJJ for SI ICE. Since the proposed CI ICE at the facility would be in compliance with NSPS Subpart IIII, the unit would also be in compliance with NESHAP Subpart ZZZZ. No further requirements apply for this engine under this regulation. 4.5 Chemical Accident Prevention Provisions The Chemical Accident Prevention Provisions, promulgated in 40 CFR 68, provide requirements for the development of risk management prevention (RMP) plans for regulated substances. Applicability to RMP plan requirements is based on the types and amounts of chemicals stored at a facility. Neither gasoline or diesel fuel is on the list of regulated substances in Subpart F of this rule; therefore, the facility is not required to develop an RMP plan under 40 CFR 68. 4.6 Utah Administrative Code, Title R307 – Environmental Quality, Air Quality In addition to the federal regulations, Title R307 of the UAC establishes regulations applicable at the emission unit level and at the facility level. The state regulations in Chapter 2 also include general requirements for facilities, such as the requirement to obtain permits to construct and operate. Source-specific standards in R307 that are potentially applicable to the proposed generator are discussed in the following sections. 27 40 CFR 63.2330 Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 11 Ramboll Confidential 4.6.1 R307-203 – Emission Standards: Sulfur Content of Fuels This regulation provides emission standards for fuel burning equipment that combusts coal, oil, or a mixture thereof. The rule does not apply to sources covered by a NSPS for sulfur emissions. While the NSPS that regulates the emergency generator engines, 40 CFR 60 Subpart IIII, does not specifically regulate sulfur emissions, it does provide a requirement for the fuel sulfur content of the diesel fuel combusted in the engines (maximum sulfur content of 0.0015% by weight). The NSPS Subpart IIII fuel sulfur content limit is more stringent than that contained in this regulation (i.e., 0.85 pounds per million British thermal unit [lb/MMBtu]). Therefore, the NSPS Subpart IIII fuel sulfur content limitation applies in lieu of the R307-203 limitation. 4.6.2 R307-305-3 – Nonattainment and Maintenance Areas for PM10: Emission Standards – Visible Emissions This rule sets standards for visible emissions in PM10 nonattainment and maintenance areas, including Salt Lake County. R307-305-3(3) states that visible emissions from diesel engines in stationary operation shall be of a shade or density no darker than 20% opacity, not exceeding three minutes in any hour.28 The proposed emergency generators would be subject to this standard. R307-305-3(4) further clarifies that visible emissions exceeding the opacity standards for short time periods as the result of initial warm-up, caused by start-up or shutdown of a facility, installation or operation, or unavoidable combustion irregularities which do not exceed three minutes in length shall not be deemed in violation, provided that UDAQ finds that adequate control technology has been applied. The applicant would be required to minimize visible and non-visible emissions during start-up or shutdown, installation, or operation through the use of adequate control technology and proper procedures. Such requirements would be satisfied through exclusive use of ultra-low sulfur diesel fuel in all generator engines onsite consistent with NSPS Subpart IIII requirements. 4.6.3 R307-309 – Nonattainment and Maintenance Areas for PM10 and PM2.5: Fugitive Emissions and Fugitive Dust This rule sets standards for control of fugitive dust and fugitive emissions in PM10 and PM2.5 nonattainment and maintenance areas, including Salt Lake County. R307-309-4 states that fugitive emissions from any source shall not exceed 15% opacity. During operation, the proposed facility would not be a source of fugitive dust since it would not have unpaved roads in operational areas and would not engage in the handling of dust generating bulk materials. 4.6.4 R307-401 – Permits: New and Modified Sources R307-401 establishes application and permitting requirements for new installations and modifications to existing installations throughout the State of Utah. As a minor source for all criteria pollutants (and associated precursor pollutants) located in a nonattainment area, the facility is categorically subject to the provisions of R307-401. The applicant would continue to comply with all generally applicable requirements found under R307-401 as evidenced in the supporting sections of this NOI application. Additional provisions that apply to modifications to existing installations located in nonattainment areas are found under R307- 403, discussed subsequently. 28 Unavoidable combustion irregularities which exceed three minutes in length must be handled in accordance with R307-107. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Federal and State Regulatory Applicability 12 Ramboll Confidential 4.6.5 R307-403 – Permits: New and Modified Sources in Nonattainment Areas and Maintenance Areas R307-403 implements the provisions of the federal nonattainment area permitting program for major sources as required by 40 CFR 51.165. The requirements under R307-403-5(1) apply to new or modified sources located in a PM10 nonattainment area that have the potential to emit more than 25 tpy of combined PM10, SO2, and NOX emissions. Salt Lake County is currently designated as attainment for PM10, so R307-403-5(1) is not applicable. Per R307-403-5(2), major sources or major modifications to existing sources located in a PM2.5 nonattainment areas must obtain ERCs. As demonstrated in Table 1, the proposed modifications would not cause the facility to be classified as a major source and the project itself would not meet the definition of a major modification to existing sources. Therefore, the requirement to obtain ERCs prior to initiating construction does not apply. 4.6.6 R307-410 – Emissions Impact Analysis The provisions of R307-410 establish the procedures and requirements for evaluating the emissions impact of new and modified sources that require an approval order under R307- 401 to ensure that the source would not interfere with the attainment or maintenance of any NAAQS in the state of Utah. The facility’s potential emissions with the newly proposed generators would not exceed any of the modeling thresholds under R307-410-4 Table 1. However, SLCDA understands that UDEQ would like the applicant to demonstrate compliance with the 1-hour NO2 NAAQS since the proposed facility modification’s NOx emissions will exceed 10 pounds per hour. SLCDA has conducted an air dispersion modeling analysis using USEPA’s recommended short-range transport dispersion model (i.e., AERMOD). This analysis was conducted in accordance with the air dispersion modeling protocol submitted to UDAQ on June 14, 2023.29 The facility’s demonstration of compliance with the 1-hour NO2 and annual NAAQS is shown in the final modeling report, provided to UDAQ under separate cover, and is summarized in Section 6. 4.6.7 R307-420 – Permits: Ozone Offset Requirements in Davis and Salt Lake County Counties Section R307-420-1 indicates that this regulation becomes effective only when Salt Lake and Utah counties are redesignated into attainment for ozone. Additionally, this regulation only applies to major sources or major modifications as defined in R307-420-2. Since the facility is not a major source and this project is not considered a major modification, the facility is not subject to this regulation. 4.6.8 R307-421 – Permits: PM10 Offset Requirements in Salt Lake County and Utah County Section R307-421-5 indicates that this regulation becomes effective only when Salt Lake and Utah counties are redesignated into attainment for PM10. Salt Lake County was redesignated as attainment for PM10 on March 27, 2020, and so this regulation is applicable. The combined emissions increase of PM10, SO2, and NOX attributable to the proposed generators at the facility is less than the 25 tpy threshold; therefore, the requirement to obtain ERCs prior to initiating construction does not apply. 29 The Modeling Protocol was approved by Dave Prey on January 4, 2022. Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Evaluation of Best Available Control Technology 13 Ramboll Confidential 5. EVALUATION OF BEST AVAILABLE CONTROL TECHNOLOGY New and modified sources of air emissions in Utah are required to implement best available control technology (BACT) for control of emissions when applying for an AO.30 Determination of BACT includes analyses pertaining to technical feasibility of potential air pollution control technologies, as well as factors such as the energy, environmental, and economic impacts of the technology. This section evaluates BACT for emissions of criteria pollutants from the emergency generators, specifically NOX, CO, VOC, PM10, PM2.5, and SO2. The emergency backup generator to be installed at the facility would be certified by the manufacturer to meet the requirements of USEPA’s Tier 2 emission standards, in accordance with the requirements of 40 CFR 60 Subpart IIII. The primary pollutant of concern is NOX, as indicated by the potential emissions of the emergency backup generators and local attainment considerations (i.e., NOX is a precursor pollutant for secondary formation of ozone, PM10, and PM2.5). Because the emergency backup generator would operate in standby mode the majority of the time, the use of engines certified by the manufacturer to meet the Tier 2 standards satisfies BACT requirements for this scenario. However, to be proactive, the applicant has evaluated additional potential control technologies that can reduce NOX emissions. 5.1 BACT Determination for NOX In accordance with the USEPA’s top-down approach for conducting BACT analyses, the applicant has reviewed potential control technologies for reducing NOX emissions from diesel- fired ICE. Of all potential technologies, those technically capable of reducing NOX emissions from diesel-fired ICE of equivalent capacity to those used at the facility include the use of (1) Selective Catalytic Reduction (SCR), (2) engines certified by the manufacturer to the USEPA’s Tier 4 emissions standards under 40 CFR 60 Subpart IIII, and (3) engines certified by the manufacturer to the USEPA’s Tier 2 emission standards under 40 CFR 60 Subpart IIII. The following sections evaluate these potential NOX control technologies for determination of BACT. 5.1.1 Evaluation of SCR SCR achieves a reduction in NOX emissions by passing a stream of urea solution into the generator exhaust, in the presence of a fixed, solid catalyst. The urea reacts with the NOX yielding nitrogen, water, and CO2. The applicant has evaluated the control effectiveness and potential energy, environmental, and economic impacts in the following subsections. SCR Control Effectiveness The control efficiency of this technology is dependent on several factors including generator load, catalyst state, and exhaust temperature. The SCR controls evaluated are estimated to achieve up to a 90% reduction in NOX emissions 31, which would equate to a NOX emissions rate of 0.44 g/bhp-hr (1.94 lb/hr/generator) for the Cummins generator. To ensure the SCR systems operate effectively, the unit must be operated and maintained in accordance with the manufacturer’s recommendations. However, per the California Air Resources Board’s 30 R307-401-5(d) 31 Based on the maximum control efficiency from USEPA’s Air Pollution Control Technology Fact Sheet, Selective Catalytic Reduction (SCR), USEPA-452/F-03-032. https://www3.epa.gov/ttn/catc/cica/files/fscr.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential (ARB) review on stationary compression ignition engines, it is stated that since SCR’s require exhaust temperatures of 260°C to 540°C (500°F-1,004°F), it may be difficult for emergency generators to meet these temperatures since most of their operations are on low loads and for short periods of time 32. Therefore, if the exhaust temperature was not met for these runs, the SCR would not activate, and the desired NOX reduction would not be met. Additionally, an increase in load size or run duration for the activation of the SCR would result in additional emissions from the engine. Evaluation of Energy Impacts of SCR The energy required to operate SCR after-treatment is minimal relative to that of a generator. During the winter months, there would be a small input of energy into the SCR unit to prevent freezing of the urea solution. Evaluation of Environmental Impacts of SCR During operation of the SCR unit, the reaction of NOX, urea, and oxygen would result in the formation of CO2 emissions to the atmosphere, in addition to the formation of nitrogen and water vapor emissions. However, the amount of CO2 emissions from urea usage is a minor contributor to the overall GHG emissions from the engine resulting from diesel combustion, and the environmental impact of the additional CO2 emissions is more than offset by the benefit of NOX reduction. Additionally, the SCR process requires the installation of reagent storage facilities, a system capable of metering and diluting the stock reagent into the appropriate solution, and an atomization/injection system at the appropriate locations in the combustion unit. Evaluation of Economic Impacts of SCR The economic impact of installing SCR technology is significant. The procurement and installation process would consume a large amount of capital, and there would also be long- term costs associated with the maintenance, repair, consumables, and catalyst storage and regeneration associated with operating the SCR units. California’s ARB also researched the cost associated with installing diesel particulate filters (DPF) and SCRs on new Tier 2 or Tier 3 engines 33. The following costs were determined based on engine size and SLCDA has conservatively assumed that the cost for SCR installation, without DPF, is equal to the difference in cost between the DPF and DPF/SCR scenario, as shown in Table 3 below. 32 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf 33 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential Table 3.

According to CARB data, SCR would result in an additional $210,000 each for the new 1,500 kW (2,012 hp) engines. This would result in ~$145,000/ton NOX removed. Additionally, this does not account for the ongoing operation and maintenance costs of the SCR system. 5.1.2 Evaluation of USEPA Tier 4 Certification 40 CFR 60 Subpart IIII requires owners and operators of new non-emergency diesel-fired ICE with a rated power output of greater than 560 kW to purchase engines that are certified by the manufacturer to the USEPA’s Tier 4 nonroad engine emission standards. As such, the proposed diesel-fired emergency backup generator to be installed at the site is not subject to Tier 4 certification. However, for completeness, the applicant has reviewed the potential use of Tier 4-certified engines at the site as a means of demonstrating BACT-level NOX emissions. For the purposes of evaluating potential NOX emissions control technologies, the applicant considers the use of Tier 4-certified engines to be effectively equivalent from an emissions performance perspective to the use of Tier 2-certified engines utilizing SCR for NOX emissions control. According to the California ARB, a Tier 4 engine supplied by a manufacturer with a DPF and SCR would be an additional $310,000 for each of the new 1,500 kW engines.34 5.1.3 Evaluation of USEPA Tier 2 Certification 40 CFR 60 Subpart IIII requires owners and operators of new emergency diesel-fired ICE to purchase engines certified by the manufacturer to the USEPA’s nonroad engine emission standards. Since the use of Tier 2-certified engines does not involve an exhaust stream control technique, there are no associated adverse environmental, energy, or economic impacts. 34 California Air Resources Board, Proposed Amendments to the Airborne Toxic Control Measure for Stationary Compression Ignition Engines. https://ww3.arb.ca.gov/regact/2010/atcm2010/atcmisor.pdf Notice of Intent to Construct Application Salt Lake City Department of Airports (SLCDA) Confidential 5.1.4 Selection of BACT for NOX Based on a limited review of USEPA’s RACT/BACT/LAER Clearinghouse (RBLC) database for diesel generators, the use of either Tier 4 engines or Tier 2 engines with SCR represents the lowest achievable emission rate (LAER) level of emission control for emergency backup generators and exceeds the BACT requirements of this minor source project. In reviewing the control techniques described above, SLCDA has determined that the Tier 2 engines meet BACT for NOX by implementing good operating practices and through purchasing an engine certified to the required Tier 2 emissions standards. Although the Tier 4 engine and Tier 2 engines with SCR are technically feasible, due to the low potential emission reduction for the generators and the high capital and annual operating costs, these options were determined to be economically infeasible. 5.2 BACT Determination for Other Criteria Pollutants Emissions of all other criteria pollutants would be less than 1 tpy for each emergency generator. Due to the low emission rates of these pollutants, they do not warrant control technology beyond those inherent to Tier 2 generators, which is considered BACT for this facility. This conclusion is consistent with the USEPA’s determination in the development of 40 CFR 60 Subpart IIII that add-on controls are not economically viable for emergency ICE. While the use of Tier 4-certified engines could potentially lower emissions of PM, the conservatively estimated potential generator emissions of PM are already minimal (0.04 tpy versus a major source threshold of 70 tpy) and are based on the maximum ratio of the manufacturer’s “Not to Exceed” emission factor, which is approximately 25% higher than the manufacturer’s “nominal” or expected emission factors. As such, the use of and significant costs associated with installing a Tier 4-certified engine would be expected to result in only minimal reductions of PM emissions (e.g., less than 0.5 tpy) at the site. Consequently, the applicant considers the use of Tier 2-certified engines to represent BACT for all other criteria pollutants. The proposed generators are certified by the manufacturer to the USEPA’s Tier 2 emissions standards, and the site will operate and maintain each engine according to the manufacturer’s emission-related written instructions and only change those emission-related settings that are permitted by the manufacturer. Further, the applicant will only combust ultra-low sulfur diesel fuel in its generators, with a maximum fuel sulfur content of 0.0015% by weight consistent with the requirements of NSPS Subpart IIII. 5.3 Conclusion The emergency generator engines to be installed at the facility are certified by the manufacturer to meet the requirements of USEPA’s Tier 2 emission standards, in accordance with the requirements of 40 CFR 60 Subpart IIII. The primary pollutant of concern from this generator is NOX, as indicated by the potential emissions and local attainment considerations as a precursor for ozone, PM10, and PM2.5. Because this emergency generator would be in standby mode the majority of the time and typically run for short periods of time, the use of engines certified by the manufacturer to meet the Tier 2 standards satisfies BACT requirements for this scenario.
