Ancillary equipment includes, but is not limited to, storage tanks, product loading operations, wastewater treatment systems, steam- or electricity-producing units (including coke gasification units), pressure relief valves, pumps, sampling vents and continuous analyzer vents. Cascaded flare system means a series of flares connected to one flare gas header system arranged with increasing pressure set points so that discharges will be initially directed to the first flare in the series (i.e., the primary flare). lf the discharge pressure exceeds a set point at which the flow to the primary flare would exceed the primary flare's capacity, flow will be diverted to the second flare in the series. Similarly, flow would be diverted to a third (or fourth) flare if the pressure in the flare gas header system exceeds a threshold where the flow to the first two (or three) flares would exceed their capacities. Corrective action means the design, operation and maintenance changes that one takes consistent with good engineering practice to reduce or eliminate the likelihood of the recurrence of the primary cause and any other contributing cause(s) of an event identified by a root cause analysis as having resulted in a discharge of gases to an affected flare in excess of specified thresholds. Corrective action analysis means a description of all reasonable interim and long-term measures, if any, that are available, and an explanation of why the selected corrective action(s) islare the best alternative(s), including, but not limited to, considerations of cost effectiveness, technical feasibility, safety and secondary impacts. Emergency flare means a flare that combusts gas exclusively released as a result of malfunctions (and not startup, shutdown, routine operations or any other cause) on four or fewer occasions in a rolling 365-day period. For purposes of this rule, a flare cannot be categorized as an emergency flare unless it maintains a water seal. Flare means a combustion device that uses an uncontrolled volume of air to burn gases. The flare includes the foundation, flare tip, structural support, burner, igniter, flare controls, including air injection or steam injection systems, flame arrestors and the flare gas header system. ln the case of an interconnected flare gas header system, the flare includes each individual flare serviced by the interconnected flare gas header system and the interconnected flare gas header system. As noted in the clarification and correction memo issued by the EPA dated Augusl27, 2013, "flare" does not include thermal oxidizers, process heaters, or other truly enclosed combustion devices. Flare gas header system means all piping and knockout pots, including those in a subheader system, used to collect and transport gas to a flare either from a process unit or a pressure relief valve from the fuel gas system, regardless of whether or not a flare gas recovery system draws gas from the flare gas SLC Refinery FMP rev. 6 - 10/1/2024 header system. The flare gas header system includes piping inside the battery limit of a process unit if the purpose of the piping is to transport gas to a flare or knockout pot that is paft of the flare. Flare gas recovery system means a system of one or more compressors, piping and the associated water seal, rupture disk or similar device used to divert gas from the flare and direct the gas to the fuel gas system or to a fuel gas combustion device. Fuel gas means any gas which is generated at a petroleum refinery and which is combusted. Fuel gas includes natural gas when the natural gas is combined and combusted in any proportion with a gas generated at a refinery. Fuel gas does not include gases generated by catalytic cracking unit catalyst regenerators, coke calciners (used to make premium grade coke) and fluid coking burners but does include gases from flexicoking unit gasifiers and other gasifiers. Fuel gas does not include vapors that are collected and combusted in a thermal oxidizer or flare installed to control emissions from wastewater treatment units other than those processing sour water, marine tank vessel loading operations or asphalt processing units (i.e., asphalt blowing stills). Fuel gas combustion device means any equipment, such as process heaters and boilers, used to combust fuel gas. For the purposes of this subpart, fuel gas combustion device does not include flares or facilities in which gases are combusted to produce sulfur or sulfuric acid. Fuel gas rystem means a system of compressors, piping, knock-out pots, mix drums, and units used to remove sulfur contaminants from the fuel gas (e.9., amine scrubbers) that collects refinery fuel gas from one or more sources for treatment as necessary prior to combusting in process heaters or boilers. A fuel gas system may have an overpressure vent to a flare but the primary purpose for a fuel gas system is to provide fuel to the refinery. Non-emergency flare means any flare that is not an emergency flare as defined in this subpart. Petroleum means the crude oil removed from the earth and the oils derived from tar sands, shale, and coal. Petroleum refinery means any facility engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants, asphalt (bitumen) or other products through distillation of petroleum or through redistillation, cracking or reforming of unfinished petroleum derivatives. A facility that produces only oil shale or tar sands-derived crude oil for further processing at a petroleum refinery using only solvent extraction and/or distillation to recover diluent is not a petroleum refinery. Primary flare means the first flare in a cascaded flare system. Process upset gas means any gas generated by a petroleum refinery process unit or by ancillary equipment as a result of startup, shutdown, upset or malfunction. Purge gas means gas introduced between a flare's water seal and a flare's tip to prevent oxygen infiltration (backflow) into the flare tip. For flares with no water seals, the function of purge gas is performed by sweep gas (i.e., flares without water seals do not use purge gas). SLC Refinery FMP rev. 6 - 10/1/2024 Reduced sulfur compounds means hydrogen sulfide (HzS), carbonyl sulfide, and carbon disulfide. Refinery process unit means any segment of the petroleum refinery in which a specific processing operation is conducted. Root cause analysis means an assessment conducted through a process of investigation to determine the primary cause, and any other contributing cause(s), of a discharge of gases in excess of specified thresholds. Secondary flare means a flare in a cascaded flare system that provides additional flare capacity and pressure relief to a flare gas system when the flare gas flow exceeds the capacity of the primary flare. For purposes of this subpart, a secondary flare is characterized by infrequent use and must maintain a water seal. Sweep gas means the gas introduced in a flare gas header system to maintain a constant flow of gas to prevent oxygen buildup in the flare header. For flares with no water seals, sweep gas also performs the function of preventing oxygen infiltration (backflow) into the flare tip. SLC Refinery FMP rev. 6 - 10/1/2024 lntroduction Summory Tesoro Refining & Marketing Company LLC, doing business as Marathon, (Tesoro) owns and operates the Salt Lake City Refinery located in Salt Lake County, Utahl. This Flare Management Plan (FMP) documents actions to minimize waste gas flow to the flares and meet the equipment work practice and operational standards set forth in 40 CFR Part 60.100a through 60.109a, also known as New Source Performance Standard (NSPS) Subpart Ja. The Salt Lake City Refinery operates three flares. The North and South flares are connected to the flare gas recovery system (FGR) and all operating units except the Sulfur Recovery Unit (SRU) and Tail Gas Treating Unit (TGTU). The FGR system was installed in 2015. The SRU Flare operates independently, services the SRU and TGTU exclusively, and is not connected to the FGR system. NSPS Ja was originally proposed in 2008 and was updated and revised for several years thereafter. The Environmental Protection Agency (EPA) published final rule amendments in the Federal Register on September 12,2012. A flare, as defined in NSPS Ja, is an affected facility and can trigger the rule requirements via construction, modification or reconstruction. The modification provisions are specified in 560.100a(cX1)-(2). Tesoro has determined that the Nor1h, South, and SRU flares have triggered modification via $60.100a(c)(1) and are therefore subject to NSPS Subpart Ja including the flare equipment work practice and operational standards. One of the work practice standards under NSPS Ja requires that a Flare Management Plan be developed and submitted to the EPA. This document fulfills the 560.103a(aX1)-(7) requirements. For each of the three affected flares at Tesoro Salt Lake City this FMP: Lists the process units connected to the flare (560.103a(a)(1)) Documents Tesoro's flare minimization efforts (560.103a(a)(2)) Describes the flare (560.1 03a(a)(3)) Evaluates baseline flow to the flare and establishes alternative baselines for alternative operating scenarios (560.1 03a(aX )) Presents procedures to minimize flaring during startup and shutdown (560.103a(aX5)) Summarizes procedures to reduce flaring due to fuel gas imbalances (560.103a(aX6)) 1 Tesoro Refining & Marketing Company LLC's parent company Andeavor merged with Marathon Petroleum Corporation in 2018. By operation of this merger, Tesoro became an indirect and wholly owned subsidiary of Marathon. Tesoro Refining & Marketing Company LLC remains the owner of the Salt Lake City Refinery. SLC Refinery FMP rev. 6 - 10/1/2024 o Describes procedures to minimize flare gas recovery system outages (560.103a(aX7)) The history of and revisions to this FMP are described in Appendix A. Focility Descriplion The Tesoro Salt Lake City Refinery processes approximately 66,000 barrels per day of crude oil, producing primarilygasoline and dieselfuel. Otherproducts include liquid propane, refineryfuelgas, jetfuel, and heavy fuel oil. Process units include Crude Distillation, Ultraformer, Fluid Catalytic Cracking with Vapor Recovery, Alkylation, Polymerization, Cogeneration, Benzene Saturation, Gasoline Hydrotreating, Diesel Desulfurization, Sulfur Recovery and Tail Gas Treating, Rail and Truck Loading Racks, Tank Farm, and Wastewater Treatment. Affected Flores The refinery has three flares. All North and South flare networks are connected to the flare gas recovery system (FGR) and provide relief for the operating units. The Sulfur Recovery Unit (SRU) Flare operates independently and services the SRU and Tail Gas Treating Unit (IGTU) and is not connected to the FGR system. Tesoro rents a thermal oxidizer to degas Group 1 tanks when they are taken out of service. The thermal oxidizer does not meet the definition of a flare as defined by 40 CFR 60.101a. The detailed specifications of the flares are included in Section 3.0 of this plan. The flares are subject to NSPS Ja based on the addition of new piping connecting refinery process units and ancillary equipment to the flare after June 24,2008. [40 CFR 560.100a(c)(1)] Flore Minimizotion Resulis The Salt Lake City Refinery has installed Flare Gas Recovery (FGR) which has reduced the baseline flaring to zero, aside from purges and sweeps, during normal operation. Since installation in 2015, the FGR system, along with emphasis on flare minimization, has significantly reduced the frequency and duration of flare events. SLC Refinery FMP rev. 6 - 10/1/2024 11 1.0 Flqre Conneclions [560.1O3o(oxl)l A list of all flare connections including refinery process units, ancillary equipment, and fuel gas systems connected to the affected flare(s) required by 560.103a(aX1) is included in Appendix B. Ancillary equipment, as defined by 560.101a, includes, but is not limited to, storage tanks, product loading operations, wastewater treatment systems, steam or electricity producing units, pressure relief valves, pumps, sampling vents and continuous analyzer vents. To complete this effort, Tesoro field-verified all flare connections after initially assembling the connection list from piping and instrumentation diagrams (P&lDs). The initial flare connection verification was conducted in 201 3 and 2014, and then updated in 201 5 after installation of the FGR system. Since 20'17, connections to the North and South flares have been reviewed periodically, including a detailed review in 2019. The flare connection list and maps are kept up to date through the refinery's management of change (MOC) process. The extent of the flare connections required to be included in the FMP is broad based on the 560.101a definition of ancillary equipment as follows: Ancillary equipment meons equipment used in conjunction with or thot serve a refinery process unit. Ancillory equipment includes, but is not limited to, storage tonks, product loading operotions, wostewoter treotment systems, steom- or electricity-producing units (including coke gasification units), pressure relief volves, pumps, sompling vents ond continuous onolyzer vents. Per 560.103a(bX2), this FMP will be updated periodically to account for flare connection changes but does not need to be resubmitted unless a primary or alternative baseline is changed, flare gas recovery is installed, or a flare monitoring election is changed. l.t North ond South Flores The North and South flares are interconnected and service all units with the exception of the SRU and TGTU. Though interconnected by FGR and cross-over connections, the North and South flares have individual water seals and can be isolated from each other when necessary. These flares share common primary and alternative baselines, as described in Section 4.0 below, and their combined flows are used to determine Root Cause Analysis (RCA) triggers. The south flare tip and pilot systems were replaced during the 2024 turnaround to ensure current best practice reliability. 1.2 SRU Flore The SRU flare is entirely separate from the North and South flares. lt services only the SRU and TGTU. Though flaring events are infrequent, the SRU flare is not considered an emergency flare for the purposes of NSPS Ja monitoring requirements. The SRU flare tip and pilot systems were replaced during the 2020 turnaround, including improved metallurgy, to improve flare and pilot reliability. SLC Refinery FMP rev. 6 - 10/1/2024 2.0 Flqre Minimizolion [S60.103o(ox2)l 560.103a(aX2) requires an assessment of whether discharges to affected flares from these process units, ancillary equipment, and fuel gas systems can be minimized. The flare minimization assessment must (at a minimum) consider the following: o Elimination of process gas discharge to the flare through process operating changes or gas recovery at the source. o Reduction of the volume of process gas to the flare through process operating changes. o lnstallation of a flare gas recovery system or, for facilities that are fuel gas rich, a flare gas recovery system and a co-generation unit or combined heat and power unit. o Minimization of sweep gas flow rates and, for flares with water seals, purge gas flow rates. Descriptions of the minimization assessment and its results are included below. 2.1 Flore Minimizotion Assessmenl The Salt Lake City Refinery conducted the minimization assessment that involved mapping and evaluating all flare connections and reviewing historical flaring events to identify potential reduction projects beyond the installation of FGR. This assessment considered the capital and annual operating costs, technical feasibility, secondary environmental impacts, and safety aspects of each potential change. See Section 2.3 for the outcomes of specific projects that have been implemented driving further flare minimization and reduction at the North and South Flares. Flare minimization measures presented here are consistent with those in the site's Consent Decree Flare Management Plan and MACT CC Flare Management Plan. As part of the current flare minimization effort at the SRU flare, each SRU flare connection was reviewed by experienced operators, operation supervisors, process engineers, project engineers, and environmental staff. During this detailed review, flare connections were discussed individually with the exception of process safety valves (PSVs), which were evaluated as a group. PSVs are, by definition, safety devices whose release is minimized via standard operating procedures. While PSV releases are minimized as part of normal operations, they can sometimes leak and contribute to vent gas volumes. Though initially addressed as a group, PSVs were discussed individually when historical flare contribution has occurred due to relief or leaks. See the SRU Flare header connection list in Appendix B for the outcomes of this individual connection minimization review. 2.2 Summory of Key Minimizotion Assessment Resulls of the North ond South Flores During planned startup and shutdown, for release events where significant flaring could occur, the existing operating procedures are reviewed to ensure that Operations personnel are familiar with the procedures and know their role. This review includes consideration of flare minimization for each planned startup and shutdown with significant flaring risk. SLC Refinery FMP rev. 6 - 10/1/2024 13 Emergency releases can be necessary to protect the equipment from damage and the community from danger. Flares are an essential safety device for refineries and must be used as such in the case of emergencies. However, steps have been taken to ensure good work practice standards in such events where emergency releases are necessary. Furthermore, the Salt Lake City Refinery utilizes FGR at the North and South Flares which increases the flare waste gas capacity of the flare system prior to flaring. Additionally, the Salt Lake City Refinery utilizes cogeneration units to consume excess fuel gas to produce power, consequently reducing the quantity of flare waste gas sent to the flares. FGR and cogeneration both decrease the amount of flare waste gas flared at the Salt Lake City Refinery by reducing fuel gas imbalance. 2.3 FIore Minimizolion lmplemenlotion ol North ond Soulh Flores 2.3.1 Procedurol Review 2.3.1.1 Updotes lo Procedures Startup and shutdown procedures are updated as opportunities for reduce flaring are identified. Any startup or shutdown event in which excessive flaring occurs are evaluated to determine if changes in procedures, plans, or equipment configurations can be effectively used to prevent or minimize flaring in the future. Variables to be manipulated will be evaluated in order to make the appropriate procedural changes. 2.3.1.2 Flore Procedurot Troining The Salt Lake City Refinery has focused on operator training and awareness of specific prevention measures and general approaches to minimizing flaring. All operators are trained on the procedures that were altered to prevent or mitigate flaring during startup, shutdown, maintenance and normal operations situations. Similarly, all affected FGR operators are trained on unit training manuals with a focus on maintaining a reliable, operational FGR as well as troubleshooting and responding to changes in flaring process conditions. 2.3.1.3 Flore Coordinolor To ensure procedures for startup and shutdown are implemented properly when flaring is anticipated, the Salt Lake City Refinery has established the Flare Coordinator role. The role of Flare Coordinator is filled by individuals as documented by the Salt Lake City Environmental Department based on the current operating conditions. The Flare Coordinator is responsible for coordinating flaring and managing all flare plans and contingencies. lt is the responsibility of the Flare Coordinator to coordinate and implement startup and shutdown sequences that balance the fuel gas system to the degree possible based on storage capacity, gas routing limitations, and operational stability. The capacity of the FGR will be monitored by the Flare Coordinator throughout the startup or shutdown process. 2.3.1.4 Refinery-Wide Stortup ond Shutdown Startup and shutdown flaring events fall into two categories: those that can be conducted without flaring and those for which flaring may be (or is likely) unavoidable. SLC Refinery FMP rev. 6 - 10/1/2024 14 Starlup and shutdown activities for which flaring can be eliminated range from small-scale maintenance activities on single pieces of equipment up to full process unit shutdowns. The key factors in determining whether flaring can be eliminated is whether there are processes capable of consuming the material vented from the equipment or units being shut down. Factors leading to flaring thus include gas routing and fuel gas demand limitations. Routing limitations may include pressure differentials, pipe configurations, operability, and other factors. Fuel gas demand limitations may be localized to the processes accepting vented material or refinery wide. The overall "robustness" of a refinery's fuel gas system (i.e., the scale of its fuel gas producers and consumers) relative to the scope of a startup or shutdown is a critical factor for the plant's ability to accommodate this activity without flaring. ln addition to the refinery-wide methods of minimizing flaring through specified startup and shutdown procedures, the methods for startup and shutdown of individual process flare units or flare networks to prevent or minimize flaring have been identified. 2.3.1.5 Fuel Gos Consumplion The key strategy used to prevent and minimize flaring during startup and shutdown is maximizing the amount of material vented from equipment which can be consumed by refinery processes rather than flared. lt is thus desirable to keep fuel gas consumers operating as long as possible while the processes that produce fuel gas are shutdown. Similarly, upon startup, fuel gas consumers are brought online first as possible to prevent or minimize flaring. Though the refinery will schedule startup and shutdown sequences with material and fuel gas balances as significant factors, there are challenges which can preclude complete implementation of this strategy. These challenges include storage capacity for both feedstocks to and products from fuel gas consuming units, gas routing limitations, and operational stability. 2.3.1.6 Venling Rote ln addition to the startup and shutdown sequences, the rate at which these activities are conducted can affect the volume of material flared. Plans for full process unit startup and shutdown events where flaring is anticipated will include an evaluation of the rate at which venting should occur to prevent or minimize flaring to the extent required by regulatory limits. At times it may be advantageous to conduct a certain aspect of the event slowly, such as when a decreased vent rate allows excess material to be consumed by another refinery process instead of exceeding the consumer's capacity. Alternatively, there are conditions when a faster rate of venting may be required. An example of this condition would be venting of inert constituents that cannot safely be routed to the FGR and must be flared. lnerting and deinventorying will be conducted by maximizing consumption of vented material and by reducing the quantity of gas required to render equipment inert in order to minimize flaring. When the overall refinery fuel gas consumption volume is high, the nitrogen can be vented to the fuel gas system or FGR without adversely affecting the combustion characteristics of fuel gas consumers. When the refinery fuel gas consumption volume is low, such as during shutdown, or when there is not sufficient fuel gas demand, the nitrogen must be vented to the flare system. Alternative means of inerting, including chemical cleaning, steam-out rates and durations, and reducing the volume of inerting gases, have been 15SLC Refinery FMP rev. 6 - 10/1/2024 evaluated for the South Area and are scheduled to be completed for the North Area prior to the next scheduled refinery tu rnaround. 2.3.2 Emergency Releose The Salt Lake City Refinery has an extensive library of robust emergency procedures. The emergency procedures outline the necessary steps to operate safely and without damage to the equipment, people and the enviornment. Each emergency procedure outlines the purpose, responsibilities of the affected employees, relevant supporting documents, materials and equipment necessary, and the procedure itself. All emergency procedures must be read and understood prior to its performance. Any deviation from the documented procedures must be documented in writing, reviewed, approved, and have proper authorization. ln the past few years, electric power outages were a significant cause of process upset flaring. The Salt Lake City Refinery has completed the following electrical power infrastructure projects to improve power reliability and minimize flaring due to local or refinery-wide power outages: Converted a single bus system at the Rocky Mountain Power (RMP) substation to a ring bus system lnstalled two functionally independent Cogen systems . Added redundant circuits to all major power distribution systems lmproved Cogen reliability by debugging protection and control settings Built a new main substation o lmproved preventative maintenance procedures . lmproved current transformer (CT) testing . lmproved ground fault detection . Reduced single points of failure o Refined load shedding operations to minimize impacts of external power interruptions The Salt Lake City Refinery has historically been served from a single overhead 46 kilovolt distribution line with single taps branching off to the various substations throughout the plant. The four new medium voltage substations installed at the refinery include redundant feeders, high speed protective relays and automatic transfer schemes. The substations are also supplied by armored tray cables that reduce exposure to lightning, faulting, and other hazards that often lead to power upsets and to flaring. 2.3.3 lmplementotion of PSV Prevention Meqsures All Process Safety Valves (PSVs) connected to the flare have three primary prevention measures as listed below. SLC Refinery FMP rev. 6 - 10/1/2024 16 1. Documented routine inspections, 2. Designing equipment to codes and standards, and 3. Alarms, including monitoring at PSV, flare flow, or seal monitoring, coupled with operator action. All three of these prevention measures reduce the flare waste gas sent to the flare header, therefore reducing the frequency and volume of flare waste gas flared. 2.3.4 lnslollotion of Flore Gqs Recovery ond Cogenerotion Unils The Salt Lake City Refinery installed a FGR in 2015. The Salt Lake City Refinery's FGR consists of three compressors, each with 1.35 MMSCFD of recovery capacity, for the North and South Flares. All three compressors are online during planned startup and shutdowns. The FGR system operated without shutdown from 20'l 5 until 2020. The FGR was taken offline for maintenance during the 2020 and 2024 turnarounds. Additional work scope during the 2020 turnaround included SRU flare tip replacement and modernization, installation of a reengineered north flare flow monitor and maintenance of the north flare and SRU flare. The recovered flare gas is routed to an amine contactor column where hydrogen sulfide (HzS) is removed from the gas. The treated recovered flare gas is sent to the fuel gas mix drum for use in the refinery fuel gas system. 2024 turnaround scope included replacement of the south flare tip, new upgraded south flare steam control valves, south flare header replacement (including port forfuture instruments), and new upgraded south flare flow meters. The Salt Lake City Refinery installed a cogeneration unit in 2003 The Salt Lake City Refinery's cogeneration system consists of two units, each with 11.8 MW capacity.

Since installation in 2015, the north flare flow meter has consistently recorded flows that do not exist resulting in over reporting of flare volume.

The north flare flow meter continues to report positive flow that does not exist, particularly during afternoon sun. The flow meter manufacturer believes these false positive flow readings are attributable to convection flows in the flare header in a direction tangential to the header axis due to a phenomenon title diurnal effect. SLC Refinery FMP rev. 6 - 10/1/2024 20 3.3.1.2 South Flore Soufh Flore Flow lnslru menlofion Specificofions The Tesoro Salt Lake City Refinery operates two co-located flow meters on the south flare. The primary flow meter is an ultrasonic GE Panametrics GF868 flare gas flow meter system that uses dual path T17 transducers. While this flow meter is well suited for most operating scenarios, it is not designed to accurately quantify low density gas streams such as occur during ultraformer hydrogen venting scenarios. During these scenarios the refinery utilizes a FCI model ST100A thermal dispersion flow meter that maintains required accuracy while measuring low density gas streams without requiring temperature or pressure compensation. The thermal mass flow meter was replaced and upgraded during the 2024 turnaround. These flow meters are installed in a representative measurement location downstream of the water seal. The ultrasonic flow meter utilizes live pressure and temperature correction. These instruments are used to report the flare flow rate at standard conditions (68"F and 1 atmosphere).

Pressure instrument tag: None required o Temperature instrument tag: None required The refinery utilizes conditional logic to determine which of these monitors is best suited for flow measurement at a particular point in time. This is done by evaluating flow in the ultraformer hydrogen vent line as a surrogate for hydrogen content in the south flare header. lf the ultraformer hydrogen flow rate, as measured by f032346, exceeds 240,000 SCFD, the south flare vent gas stream is considered to have high hydrogen content and the thermal mass flow meter may be selected as the most accurate flow measurement. lt should be noted this flow is generally zero except during episodic venting or ultraformer hydrogen. ln all other cases the primary flow monitor, the ultrasonic instrument, is selected. Additionally, during period of maintenance or instrument malfunction, data from either instrument may be substituted to ensure redundancy and high instrument availability.

On July 27,2015, the EPA approved an Alternative Monitoring Plan (AMP)for the Tesoro Salt Lake City Refinery regarding the concentration of the span gas used to check the daily calibration drift and high range validation standards used during cylinder gas audits (CGAs). Tesoro requested that the extremely high concentration hydrogen sulfide calibration gas which would be required by 40 CFR 60.13(dX1) and Performance Specification 5 for the total sulfur CEMS at the SRU flare be eliminated. The approved AMP requires Tesoro to conduct a linearity check over each of the three methods described above every three (3) years. An R-squared correlation coefficient value of 0.95 or greater from the best-fit linear trend is considered to be within tolerance. Consistent with 40 CFR 560.107a(a)(2Xv), compliance with the HzS concentration requirements in 560.103a(h) for the SRU flare is demonstrated by the TRS analyzer. The span of Method 1 for the SRU TRS analyzer is 20-1,200 ppm as total sulfur and satisfies the requirement in 560.107a(aX2)(v) that the instrument has a span capable of accurately measuring concentrations between 20 and 300 ppmv. The facility has at times experienced downtime with its gas chromatographs, in particular the total sulfur units. During high analyzer downtime scenarios, the facility may rent certified continuous emission monitoring systems to improve downtime performance. All analyzer serial numbers are reported in quarterly continuous emission monitoring reports submitted to the Utah Division of Air Quality. SLC Refinery FMP rev. 6 - 10/1/2024 4.0 Boseline Flow qnd Allernqlive Operoting Scenorios [560.1 03o(ox4)l NSPS Subpart Ja requires that a primary baseline flow rate be established for each flare. Alternative operating scenarios with associated alternative baselines may also be established. Under NSPS Subpart Ja, the trigger for conducting a mandatory root cause analysis (RCA) is 500,000 standard cubic feet per day (SCFD) over the primary baseline during normal operations or 500,000 SCFD over any alternative baseline while operating under the defined alternative operating scenarios. Required RCAs must be completed within 45 days of the triggering event. A RCA does not need to be conducted for startup and shutdown events if the procedures defined in Section 5.0 are followed, though the emissions associated with these events must be reported. Though the Tesoro Salt Lake City Refinery has three flares, there are two distinct flare systems. The North and South Flares are interconnected and their individual flows and SOz emissions are combined for baseline and compliance calculations. The SRU Flare operates independently. Therefore, there are two systems for which baseline flow and alternatlve operating scenarios have been established. The primary and alternative baselines for the Salt Lake City Refinery flares are summarized in Table 4-1 in Section 4.3. Any changes to the primary baseline flow or alternative baselines will require resubmission of this FMP. 4.1 Primory Boseline Flow Rote [560.103o(oXaXi)l The primary baseline flow rate for the North and South Flare system, connected via FGR system, is zero. The FGR system has been designed to capture all non-process upset gas flows. The RCA trigger for the North and South flare system is thus 500,000 SCFD. This trigger applies to any Z4-hour period and must be calculated on a rolling basis. The SRU Flare has two regular contributions due to sweep gas; a natural gas sweep on the SRU flare header and a nitrogen sweep on the Tail Gas Treating Unit (TGTU). These sweeps are necessary to ensure the flare headers are purged of oxygen and that potentially acidic liquid does not accumulate. The primary baseline flow for the SRU flare is 28,800 SCFD based on the minimum required flare sweeps and the RCA trigger for the SRU flare is thus 528,800 SCFD. This trigger applies to any 24-hour period and must be calculated on a rolling basis. 4.2 Allernotive Operoling Scenorios [560.1 O3o(oXaXii)l The following alternative operating scenarios have been established based on past operating conditions and updated to account for the anticipated flare minimization impacts of the FGR system. These are appropriately designated as alternative operating scenarios, with corresponding alternative baselines, because their root causes are understood and cannot be avoided without compromising the safety or operational stability of the refinery, which would present risks of greater environmental impacts. These scenarios are updated periodically based on learnings from previous flare events. SLC Refinery FMP rev. 6 - 10/1/2024 27 Alternative operating scenarios have been established for the following conditions for the North and South Flare System: 1. Fuel gas long or low fuel gas NHV while maximizing gasoline production 2. Diesel Desulfurization Unit (DDU) maintenance, outage or catalyst change 3. Diesel #1 production 4. Plant turnarounds 5. North flare hydrogen venting to stabilize vent gas flow meter low range readings When the refinery is operating under one of these alternative operating scenarios, and thus subject to an alternative baseline, that status will be documented. Documentation will include the conditions qualifying the operations as one of the alternative operating scenarlos, the flare gas volume and sulfur content for the duration of the event, and the procedures utilized to minimize flaring. To minimize the environmental impact of alternative operating scenarios, in 2017 the refinery installed an ultraformer hydrogen vent line that allows the facility to preferentially flare a hydrogen rich stream while keeping higher emitting streams in the FGR system. Ultraformer hydrogen vent gas has a preponderance of hydrogen which has a high effective Btu content and emits less regulated pollutants when combusted than gas stream with a higher hydrocarbon content. This also allows the facility to reject hydrogen from the refinery fuel gas system to ensure available gas provides safe and stable combustion, thereby minimizing the volume and emissions intensity of gasses flared and the amount of supplemental natural gas needed to maintain fuel gas NHV. Preferentially venting ultraformer hydrogen is a key minimization effort for each of the alternative operating scenarios. During the first three alternative operating scenarios, the flare gas composition is expected to be primarily hydrogen. There are no alternative baselines for the SRU Flare. 4.2.1 Alternolive Operoting Scenqrio #l - Fuel Gos [ong/[ow NHV while Moximizing Gosoline Produclion When the refinery is operating in a manner that maximizes gasoline production, a refinery fuel gas imbalance may result that necessitates flaring of excess refinery fuel gas that cannot be consumed by refinery process heaters and boilers, either due to low quality (NHV) or excess refinery fuel gas generation. Low heat content in fuel gas causes process heater and boiler flames to become unstable and presents an unacceptable process safety risk. This alternative operating scenario has been established to describe this condition, along with the anticipated flare gas volume and the procedures to minimize flaring while the facility is refinery fuel gas long/low NHV. 4.2.1.1 Alternotive Operoting Scenorio #l Rotionole The Salt Lake City Refinery supplies gasoline to meet market demand. Gasoline production may potentially cause a refinery fuel gas imbalance (long/low NHV). By preferentially venting ultraformer hydrogen during this scenario, the volume and emissions intensity of the flare event is minimized. SLC Refinery FMP rev. 6 - 10/1/2024 4.2.1.2 Alternolive Operoting Scenorio #l Doily Flow ond Expecled Durotion The anticipated daily flow when refinery is fuel gas long/low NHV while maximizing gasoline production is 1,500,000 standard cubic feet per day (SCFD). The duration of this condition varies due to market demand, fluctuations in liquefied petroleum gas (LPG) recovery in the FCCU, hydrogen production at the Ultraformer Unit (UFU), and efficiency fluctuations in the refinery furnaces and steam production. 4.2.1.3 Aliernqtive Operoting Scenorio #l Boseline The alternative baseline for Alternative Operating Scenario #1 is 1,500,000 SCFD. When the refinery is determined to be operating under this scenario, the RCA trigger for the North and South Flare System will thus be 2,000,000 SCFD (1,500,000 + 500,000 SCFD). 4.2.1.4 Allernotive Operoting Scenorio #1 Procedures for Flore Dischorge Minimizotion During fuel gas long scenarios while maximizing gasoline production, the refinery takes the following steps to minimize flaring: . When possible, venting to flare will preferentially be achieved through the UFU hydrogen vent to flare. This minimizes hydrocarbon flow to the flare. r Natural gas supplementation is minimized except as needed to maintain fuel gas quality (BTU/SCF) to ensure safe and correct operation of boilers and fired heaters. o Refinery steam generation is maximized. o Operating parameters are adjusted as practical while still meeting gasoline demand Detailed procedures are described in the refinery's Fuel Gas Balance Guidelines (OPS-OI-005). 4.2.2 Allernolive Operollng Scenorio #2 - DDU Mointenonce or Cololysl Chonge The DDU requires preventative maintenance and catalyst changes, which reduces the refinery hydrogen demand and leads to a refinery fuel gas long scenario. To minimize the environmental impact of this scenario, in 2017 the refinery installed an ultraformer hydrogen vent line that allows the facility to preferentially flare a hydrogen rich stream while keeping higher emitting streams in the FGR system. This also allows the facility to reject hydrogen from the refinery fuel gas system to ensure available gas provides safe and stable combustion, thereby minimizing the volume and emissions intensity of gasses flared. 4.2.2.1 Allernotive Operoling Scenorio #2 Rotionole The DDU must be maintained at a high operating level to ensure the sulfur specifications for diesel fuel are met. Maintaining this level of operation can require the unit to be shut down independently from the rest of the refinery, leading to a fuel gas long scenario. SLC Refinery FMP rev. 6 - 10/1/2024 29 By preferentially venting ultraformer hydrogen during this scenario, the volume and emissions intensity of the flare event is minimized. 4.2.2.2 Alternolive Operoling Scenorio #2 Doily Flow ond Expecled Durolion The anticipated daily flare flow when the DDU is shut down for maintenance or catalyst change is 3,500,000 SCFD.

When the refinery is determined to be operating under this scenario, the RCA trigger will thus be 10,000,000 SCFD (9,500,000 + 500,000 SCFD). 4.2.2.4 Allernolive Operoling Scenorio #2 Procedures for Flqre Dischorge Minimizolion During refinery fuel gas long scenarios due to DDU maintenance or catalyst change, the refinery takes the following steps to minimize flaring: r lf feasible, maintenance and catalyst changes are conducted with a DDU slowdown rather than full shutdown o When possible, venting to flare will preferentially be achieved through the UFU hydrogen vent to flare. This minimizes hydrocarbon flow to the flare. o Natural gas supplementation is minimized except as needed to maintain fuel gas quality (BTU/SCF) to ensure safe and correct operation of boilers and fired heaters o Refinery steam generation is maximized . Operating parameters are adjusted as practical Detailed procedures are described in the refinery's Fuel Gas Balance Guidelines (OPS-OI-005). 4.2.3 Allernolive Operoling Scenorlo #3 - Diesel #l Production During the winter, the refinery produces Diesel #1, which reduces hydrogen demand due to the reduction of sulfur compounds and heavy components in the feed. 4.2.3.1 Allernotive Operoting Scenorio #3 Rotionole During a Diesel #1 run, light distillate is run through the DDU which leads to a significant decrease in hydrogen demand. Diesel #1 runs are generally conducted twice per month in the winter and may lead to a refinery fuel gas long or low NHV scenario. By preferentially venting ultraformer hydrogen during this scenario, the volume and emissions intensity of the flare event is minimized. SLC Refinery FMP rev. 6 - 10/1/2024 4.2.3.2 Allernotive Operoling Scenorio #3 Doily Flow ond Expected Durotion The anticipated daily flare flow during Diesel #1 runs is 6,500,000 SCFD.

When the refinery is determined to be operating under this scenario, the RCA trigger will thus be 7,000,000 SCFD (6,500,000 + 500,000 SCFD). 4.2.3.4 Allernolive Operoting Scenorio #3 Procedures for Flore Dischorge Minimizotion During refinery fuel gas long scenarios due to Diesel #1 runs, the refinery takes the following steps to minimize flaring: o When possible, venting to flare will preferentially be achieved through the UFU hydrogen vent to flare. This minimizes hydrocarbon flow to the flare. o Natural gas supplementation is minimized except as needed to maintain fuel gas quality (BTU/SCF) to ensure safe and correct operation of boilers and fired heaters. . Refinery steam generation is maximized o Operating parameters are adjusted as practical Detailed procedures are described in the refinery's Fuel Gas Balance procedure (OPS-Ol-005). 4.2.4 Alternolive Operoling Scenorio #4 - Plonl Turnqround Approximately once every three to six years the refinery undergoes an extended outage for maintenance and/or project work. During turnarounds all or part of the plant may be shutdown. Depending on the nature and extent of work being performed the duration of these events can last several weeks. Generally, the greatest risk of flaring during turnarounds occurs during shutdown at the beginning of the event and startup at the end of the event. Turnaround work scope often involves physical entry of pro€ess vessels by workers. To allow safe entry into vessels, during shutdown the vessels are de-inventoried, flushed with process materials, steam cleaned (sometimes with chemical cleaning agents), purged with inert gasses and vented to the atmosphere, fuel gas system or flare system (or some combination thereof). During startup, the vessels must be purged of oxygen priorto introducing process materials. Each scenario where a portion of the plant is prepared for turnaround work or returned to operational service is evaluated individually. 31SLC Refinery FMP rev. 6 - 10/1/2024 Shutdown and startup sequencing and duration is planned to balance safety, flare minimization, secondary environmental effects, operability and to minimize downtime. While startup and shutdown flare minimization procedures detailed in Section 5 are applied to turnarounds, turnarounds are distinct from more common outages because of the extent of units being shut down, the extent of cleaning involved and the potential to shutdown flare gas management systems such as headers, flare gas recovery equipment and the actual flares. Purging process vessels and piping with inert gasses such as steam or nitrogen causes challenges maintaining required flare gas or fuel gas net heating value and often requires supplementing with natural gas. 4.2.4.1 Aliernotive Operoling Scenorio #4 Rotionole All refinery equipment must be periodically shut down for maintenance or modification to ensure ongoing safe and reliable operation. Because of the interconnected nature of operational units, these activities are generally grouped into partial or full plant turnarounds. 4.2.4.2 Allernotive Operoling Scenorlo #4 Doily Flow ond Expected Durolion The anticipated daily flare flow when the partial or full'refinery is shut down or started up for turnaround is 5,00,000 SCFD. The anticipated duration for each event is one to three months depending on the nature and extent of work being performed. 4.2.4.3 Allernotive Operoting Scenorlo #4 Boseline The alternative baseline for the North and South Flare System for Alternative Operating Scenario #4 is 6,000,000 scFD. When the refinery is determined to be operating under this scenario, the RCA trigger will thus be 6,500,000 SCFD (6,000,000 + 500,000 SCFD). 4.2.4.4 Allernotive Operoling Scenorio #4 Procedures for Flore Dischorge Minimizotion During turnaround scenarios, the refinery takes the following steps to minimize flaring: Frequency of turnarounds is minimized to the extent practicable. Work is sequenced to contain process gasses in the refinery fuel gas system to the extent practicable. Deinventory, flushing, steaming, chemical cleaning and purging activities are planned to balance safety, flare minimization, secondary environmental effects and operability. Natural gas supplementation is minimized except as needed to maintain fuel gas quality (BTU/SCF) to ensure safe and correct operation of boilers and fired heaters and compliance with environmental limitations.

The refinery CD includes stringent 30 day and 365 day flare volume caps. The refinery has experienced convection flows perpendicular to the header axis in the north flare header that do not represent actual flow to the flare but jeopardize compliance with these flare caps. This effect has been documented in published literature, including Flore Gos Ultrasonic Flow Measurement with lmproved Accuracy ot Low Flow ond Enhanced lmmunity to Cross FIow (James E Matson et. al., The Americas Flow Measurement Conference, April 2012). During these conditions, the refinery has found that venting a small volume of hydrogen via bypass to the flare header disrupts convection flows and results in a more accurate flow reading. This is generally accomplished with third-party supplied high purity hydrogen. Hydrogen is excluded from the CD flare caps, thereby resulting in improved compliance with the CD flare caps, but a slight increase in flows measured again the NSPS Ja flare caps. As previously noted, hydrogen has a high Btu value, does not result in emissions of regulated pollutants, and reduces visible flare emissions. 4.2.5.1 Alternotive Operoting Scenorio #5 Rotionole The Salt Lake City Refinery complies with multiple, inconsistent flare regulations. This practice has been adopted to enhance compliance with CD requirements. 4.2.5.2 Allernotive Operoling Scenorio #5 Dolly Flow ond Expecled Durotion The duration of this practice depends on the current compliance status of multiple regulations. The refinery has an incentive to minimize this practice as it is generally accomplished with purchased high purity hydrogen. 4.2.5.3 Allernotive Operoling Scenorio #5 Boseline The alternative baseline for Alternative Operating Scenario #5 is 500,000 SCFD. This quantity is based on the experience of the refinery. When the refinery is determined to be operating under this scenario, the RCA trigger for the North and South Flare System will thus be 1,000,000 SCFD (500,000 + 500,000 SCFD). 4.2.5.4 Allernolive Operoling Scenorio #5 Procedures for Flore Dischorge Minimizotion During north flare hydrogen venting scenarios, the amount of hydrogen vented will be minimized as practicable to enhance compliance with other regulatory requirements.

Detailed procedures are included in the refinery's Flare Management Plan and the unit startup and shutdown procedures. Per 560.103a(dX3): lf the dischorge from o flore is the result of a plonned stortup or shutdown of o refinery process unit or ancillory equipment connected to the affected flare and the procedures in poragroph (a)(5) of this section were followed, a root couse onolysis and corrective oction onalysis b not required; however, the dischorge must be recorded os described in 560.108a(c)(6) and reported as described in 560.108a(d)(s). Section 5.1 below describes the procedures required by $60.103a(a)(5). lmplementation of these procedures will be documented for each planned startup and shutdown to demonstrate compliance with 560.103a(dX3). When the procedures are implemented, a RCA is not required for flow in excess of the RCA triggers described in Section 4.0, though the discharge must be recorded and reported. The refinery will verify that these procedures have been followed by completing the Startup and Shutdown Flare Minimization Checklist in the Flare Management Plan RWP. Under this checklist, the refinery will evaluate each opportunity for flare minimization and document the course chosen to best balance safety, flare minimization, secondary environmental effects, and operability. 5.1 lmplemented Stortup ond Shuldown Flore Flow Minimizolion Procedures A pre-shutdown flare evaluation will be conducted for each planned startup and shutdown of the refinery, individual area, process unit, or system with significant flaring potential. The flare evaluation will document each element that may result in flaring along with the minimization procedure described below and in the refinery's Flare Management Plan. For the North and South Areas, the shutdown of individual pieces of equipment or small systems that can be accommodated by the FGR operator without flaring do not require a full flare evaluation. ln such cases, the operator of the unit in which the small-scale shutdown is taking place will coordinate with the FGR operatorto ensure there is sufficient capacity in the FGR system to capture all vent gases from equipment and avoid flaring. Because a flare minimization evaluation of the procedures belowwill not be conducted, the RCA exemption cited in 560.103a(dX3) will not apply in these cases. Planned shutdowns in the SRU and TGTU will be evaluated when the activity poses a risk of exceeding the flow or SOz RCA triggers. SLC Refinery FMP rev. 6 - 10/1/2024 35 5.1.1 Storlup Floring Risks During planned startups, there are risks of flaring due to the following operations: 1. Refinery fuel gas imbalance 2. Evacuation of oxygen and inert gases from operating units 3- Pressure control 5.1.2 Procedures to Minimize Slorlup Floring The flaring risks cited in Section 5.1.1 will be addressed by the following procedures: 1.Refinery fuel gas imbalance will be prevented, to the extent possible, by coordinating the sequence and rate of startup and by following the procedures described in Section 5.'1. When safe and practicable, the refinery will start up refinery fuel gas consumers prior to fuel gas generators and coordinate their rates to prevent a refinery fuel gas long scenario. When a refinery fuel gas long scenario cannot be avoided, its duration and volume will be limited to the extent practicable. Evacuation of oxygen and inert gases from operating units may require flaring when it is unsafe to vent these gases to the FGR system due to safety or operability concerns (e.9., when these materials would adversely affect the refinery fuel gas system). When practicable, this venting will be coordinated to minimize the hydrocarbons vented from the unit or other operating units due to the water seal being broken. Upon startup, many vessels require venting to the flare header for pressure control until steady state operating conditions are achieved. When practicable, this venting will be planned to occur when the FGR system is online and the refinery fuel gas system is able to receive and effectively combust the vented gases. When the FGR system is unable to accept the vented gases, efforts will be made to limit the volume and duration of flaring. Shuldown Floring Risks planned shutdowns, there are risks of flaring due to the following operations: Depressuring equipment and operating units Final deinventorying of liquid and low-pressure vapor from equipment and operating units Cleaning equipment and operating units using steaming and chemical cleaning Gas routing limitations due to offline equipment Refinery fuel gas imbalance 5.1.3 During 1. 2. 3. 4. 5. 2. 5.1.4 Procedures lo Minimize Shutdown Flqring The flaring risks cited in Section 5.1.3 will be addressed by the following procedures: 1. Equipment will be depressured to the refinery fuel gas system when feasible based on piping and equipment pressure. When direct depressuring to the refinery fuel gas system is infeasible, the equipment will be vented to the flare header, recovered through the FGR system and sent to the SLC Refinery FMP rev. 6 - 10/1/2024 amine treating and refinery fuel gas systems. Any hydrocarbons unable to be vented to the FGR system which must be flared will be limited to the extent possible without compromising safety. Final deinventorying of liquid and low-pressure vapor from equipment and operating units will be achieved using the FGR system, when feasible. Any hydrocarbons unable to be vented to the FGR system which must be flared will be limited to the extent possible without compromising safety. After equipment is deinventoried it needs to be rendered inerl by removing hydrocarbons so the equipment residuals are below specified safety and environmental limits. lnerting is achieved by a combination of steaming and, when practicable, chemical cleaning. o Steaming is required for all inerting efforts including those supplemented by chemical cleaning, which reduces the overall volume of steam required. When safe and technically feasible, cleaning steam will be condensed and removed from the flare system. Condensers can be used when suitable discharge ports are available from the equipment being deinventoried, when it is practicable to coordinate their use, and when it is feasible to dispose of their liquid discharge. When using condensers is not feasible, steaming through the FGR system will be used if steaming to FGR would not exceed the temperature limits of the compressors or reduce the refinery fuel gas heating value below the minimum requirement of 740 btu/scf. lf steaming to FGR is not feasible based on the conditions cited above, steaming to the flare may be required. Steaming to the flare displaces the water seal and allows all interconnected equipment to vent directly to the flare. ln such cases, steaming will be conducted as quickly as possible to minimize the flaring of vent gas from interconnected equipment. Chemical cleaning reduces flaring emissions and reduces the duration of preparing the equipment for vessel entry. Chemical cleaning is used when safe and technically feasible. Gas routing limitations due to offline equipment arise when interconnected systems are required to be shut down in a sequence that prevents certain units and equipment from routing their gases to the refinery fuel gas or FGR systems. The sequence of unit and equipment shutdown will be considered to reduce gas routing limitations and to avoid flaring unless doing otherwise would present a greater risk to safety, flaring, or secondary environmental impacts via operability. 5.2 Plonned Stortup ond Shuldown Flore Flow Minimizotion Procedures Additional methods of minimizing flaring during planned startups and shutdowns are being evaluated for future implementation including expanded use of condensers and chemical cleaning. Flaring performance during planned startups and shutdowns will be monitored moving fonvard and procedures will be updated as opportunities to further minimize flaring are identified. 4. SLC Refinery FMP rev. 6 - 10/1/2024 37 6.0 Fuel Gos lmbolqnce Flore Minimizqtion Procedures [560.1 03o(ox6)l Tesoro Salt Lake City has well-established procedures for addressing refinery fuel gas imbalances and minimize flaring. These procedures are described in Section 6.'l below. 6.1 lmplemenled Fuel Gos lmbolonce Flore Flow Minimizotion Procedures ln conjunction with the five (5) alternative operating scenarios described in Section 4.0 of this FMP, flare minimization during refinery fuel gas imbalances is achieved by preventing, when possible, refinery fuel gas long scenarios, preparing for those which are unavoidable, and responding to them appropriately. Preventing refinery fuel gas long scenarios, when practicable, is achieved by coordinating production rates and planned outages. The two primary contributing causes to refinery fuel gas long scenarios are misalignment between refinery fuel gas producers and refinery fuel gas consumers, and high inventories of propane and butane. When practicable, outages of refinery fuel gas users will be coordinated with reduced rates or outages at refinery fuel gas producers, primarily the FCCU and the UFU. The Salt Lake City Refinery endeavors to manage propane and butane inventories to ensure these gases do not need to be vented to the flare network when insufficient refinery fuel gas demand exists to prevent flaring. Preparation for unavoidable refinery fuel gas long scenarios is focused on minimizing propane and butane inventories prior to the events. By limiting inventories to the extent practical prior to the refinery fuel gas imbalance events, the quantity of propane and butane flared is reduced. Tesoro Salt Lake City's Standard Operating lnstruction (OPS-Ol-005) contains the detailed instructions for minimizing flaring during refinery fuel gas imbalances when they cannot be prevented. The key elements of this work instruction include minimizing natural gas supplementation, decreasing refinery fuel gas production, and increasing refinery fuel gas consumption. Strategies for achieving these goals are described in Sections 6.1.1-6.1.3. The procedures in OPS-OI-005 have proven sufficient to address refinery fuel gas imbalances during normal operations. Abnormal operating conditions, including planned or unplanned outages in one or more units or areas, are addressed in Sections 4.0 and 5.0 of this flare management plan. 6.1.1 Minimize Nqlurol Gos Supplementoiion When a refinery fuel gas long scenario is identified, natural gas supplementation will be minimized to the refinery fuel gas system as soon as practicable. 6.1.2 lncreose Fuel Gos Consumplion Refinery fuel gas consumption will be increased by maximizing the Cogen firing rate, increasing the rate and subsequent refinery fuel gas demand at key refinery fuel gas consuming units, and maximizing hydrogen uptake as practicable. SLC Refinery FMP rev. 6 - 10/1/2024 38 Maximizing the Cogen firing rate will generate electrical power and steam for the refinery. ln cases where Cogen is at its maximum rate or othenvise limited, refinery fuel gas may also be routed to the Cogen Duct Burner to produce additional steam. During periods of fuelgas imbalance, refineryfuel gas consuming units, including the Crude Unit, DDU, and Benzene Saturation Unit (BSU), will increase production to consume excess refinery fuel gas. Hydrogen inputs to the refinery will be reduced to the degree practicable to further limit the energy input to the refinery and maximize refinery fuel gas usage. 6.1.3 Decreose Fuel Gos Produclion Refinery fuel gas production will be reduced by decreasing the FCCU operating temperature, decreasing the feed rates to the FCCU and UFU to the extent required to comply with regulatory flare volume caps, and increasing propane recovery at the following units: Vapor Recovery Unit (VRU), Ultraformer Unit (UFU), Diesel Desulfurization Unit (DDU), and Benzene Saturation Unit (BSU). Decreasing the operating temperature of the FCCU reduces the amount of refinery fuel gas produced in the unit. ln most minor refinery fuel gas imbalance situations, this is sufficient to restore balance. lf reducing the temperature of the FCCU is not sufficient, the following additional steps may be taken. Decreasing the feed rate to the FCCU and UFU, to the extent necessary to comply with regulatory flare volume caps, will reduce refinery fuel gas production. Feed rates are adjusted, as needed, to bring the refinery fuel gas production and consumption into balance. The feed rates are reduced only to the extent necessary to comply with regulatory flare volume caps or their specified minimums, below which there is a significant risk of instability and increased emissions due to an unplanned shutdown. lf decreasing the operating temperature in the FCCU and decreasing the feed rate of the FCCU and UFU, paired with the increase of refinery fuel gas consumption described in Section 6.1.2, are insufficient to restore balance to the refinery fuel gas system, refinery fuel gas production can be further reduced by increasing the recovery of propane at the VRU, UFU, DDU, and BSU. Propane recovery is normally maximized during refinery operation but can be moderated at times to balance storage capacity. Under a refinery fuel gas long scenario, increasing inventories of propane is beneficial for reducing the volume of refinery fuel gas. 6.2 Plonned Fuel Gos lmbolonce Flore Flow Minimizotion Procedures There are currently no planned refinery fuel gas imbalance flare flow minimization procedures that have not already been implemented. The refinery's flaring will be evaluated moving forward and procedures will be updated when safe, technically feasible, and appropriate. SLC Refinery FMP rev. 6 - 10/1/2024 39 7.0 Flore Gos Recovery Ouloge Reduclion Procedures [S60.1 03o(ox7)l 7.1 lmplemenied Flore Gos Recovery Outoge Reduction Procedures FGR system outage reduction procedures include the following categories, each of which are described in more detail below: 1. Design 2. Preventative Maintenance 3. Operating Approach 4. Online Monitoring 5. Operator Training The FGR system has been designed to minimize outages by including three liquid ring seal compressors, redundant systems for online maintenance, and online monitoring. The three compressors will operate in primary, secondary, and backup roles as described in the operating approach section below. Redundant systems include key flow, pressure, and other monitoring instrumentation, spare pumps, multiple fans for the liquid ring water cooling system, and duplicate ring water basket strainers to allow for online swapping, cleaning, and maintenance. The FGR system has been designed with extensive online monitoring to ensure the system is operating effectively prior to high flare gas recovery loads, detect problems proactively, and determine when maintenance is required as described below. Preventative maintenance on the FGR compressors and supporting systems are conducted in accordance with the manufacturers'recommendations. The manufacturer's recommended preventative maintenance includes visual inspections, measurement of key parameters, lubrication checks, and filter replacements. Detailed maintenance procedures and schedules are in the compressors'operation and maintenance manual. The installation of three compressors, each of which is capable of handling the refinery's normal flare flow, enables timely and effective completion of preventative maintenance. As described below, one compressor operates in manual mode while the other two operate and respond to flare header conditions automatically in primary and secondary modes. This configuration allows preventative maintenance to be conducted on any compressor except during rare times when all three compressors are needed to manage the flare header flow, usually associated with shutdown activities. Preventative maintenance on the FGR system's supporting equipment is scheduled to coincide with times when flare flows are very low or during facility shutdowns. The three FGR compressors installed at the Salt Lake City Refinery allow for a flexible operating approach that allows the refinery to adapt to different operating conditions while maintaining the compressors as described above. One compressor will typically operate in primary service, another in secondary service, and the last in manual service. Each compressor has been designed to capture the anticipated refinery flow during normal operations and can serve in the primary, secondary, or manual mode. The primary compressor will operate continuously. When there is not enough vent gas to meet the compressor's required minimum, a portion of the compressed gas is recycled. The secondary compressor will come SLC Refinery FMP rev, 6 - 10/1/2024 40 online when flare header pressure rises to a set point that indicates the primary compressor has reached its capacity. When the suction pressure drops and the recycle valve is required to open, the secondary compressor will automatically shut down. The manual compressor may be started directly by either the board or field operator during times when flare header loads are anticipated to exceed the primary and secondary compressors' capacities. Prior to the startup of any compressor, specific conditions must be met to ensure safe and reliable operation. The FGR system has extensive online monitoring for the compressors, seal drums, and their supporting equipment. Online monitoring systems have been designed to alarm initially when operating conditions approach their limits to allow operators to take corrective action. lf the operating conditions cannot be returned to normal operating ranges, the system will automatically shut down the compressor to prevent unsafe conditions and damage to the compressors and other refinery equipment. The compressors will only be restarted after all parameters are returned to normal ranges. All refinery operators have been trained on the basic operation of FGR to ensure they understand how the flare gas loads affect the system. The FGR operators and maintenance personnel have received additional training on the control logic, alarms, operating approach, troubleshooting, and maintenance of the FGR system. While the FGR system has operated almost continuously since it was installed in 2015, it underwent extensive maintenance during plantwide turnarounds in 2020 and 2024. These maintenance periods were minimized in accordance with site CD requirements. Since the FGR system has been operating it has consistently surpassed the availability requirements established in the facility's consent Decree. 7.2 Plonned Flore Gos Recovery Outoge Reduction Procedures There are currently no planned flare gas recovery outage reduction procedures that have not been implemented. The Salt Lake City Refinery will monitor FGR system uptime and the causes of any outages, then update the procedures if necessary.
