Note: Tesoro failed to conduct a CGA for the TRS monitor on the north flare. A RATA was
conducted during 3Q2024 for H2S. However due to a scheduling anomaly, a resent in the
maintenance work order system, and an errant date entry, the CGA was not conducted until
October 10, 2024 (10 days after the quarter). This appears to be an isolated incident and does
not appear to be consistent with normal compliance related items at the facility.

SOURCE INSPECTION
SUMMARY EVALUATION: Tesoro maintains its CEMS as required in R307-170 and 40 CFR 60.13.

CURRENT
RECOMMENDATIONS: All deviations appear to be a result of breakdown or process related problems
that do not warrant issuing a violation.

Tesoro was in compliance during this reporting period. No further enforcement
actions should be taken.

Tesoro’s NSPS monitoring system meets the performance standards of 40 CFR
60, Appendix B Performance Specifications.

Tesoro failed to conduct a CGA for the TRS monitor at the north flare. A
warning letter should be sent noting the failure.

HIGH PRIORITY
VIOLATOR (HPV): No

RECOMMENDATION
FOR NEXT INSPECTION: Check DAS for daily zero and span drift.
Check the QC program to ensure that monitor drift is being tracked and that the
source can identify excessive drift.

HAND DELIVERED
Re: Quarterly CEMS Report - Third Quarter 2024
Dear Mr. Bird,
A digital file was submitted via email containing the Third Quarter 2024 report for the Continuous
Emission Monitors Systems (CEMS) located at the Tesoro Refining & Marketing Company, LLC in Salt
Lake City. This file contains data for forty-nine (49) CEMS at the Tesoro facility. The analyzers are
listed below:
o Two Oz, two CO, and two COz monitors at the Fluid Catalytic Cracking Unit Regenerator (Regen)
o SO: low, SOz high, O:, flow monitors at the Sulfur Recovery Unit (SRU)
o HzS monitor for the refinery fuel gas located at the V-917 Fuel Gas Mix Drum
o Two HzS monitors at the J-80 Sweet Gas Compressor feeding the Cogeneration Turbine Units

installed downstream of the Electrostatic Precipitator on the FCCU.
Two CO, two SO: (high and low methods), two NOx (high and low methods), and two Ou at the
Carbon Monoxide (CO) Boiler bypass stack of the FCCU, upstream of the CO Boiler. These
analyzers are used to monitor the gas discharged from the CO Boiler Bypass stack in event of a
discharge
The affected facilities consist of the Regen, CO Boiler Bypass, Wet Gas Scrubber, SRU, V-91 7 Fuel Gas
Mix Drum, Cogen, North Flare, South Flare and SRU Flare. Each CEMS at the Regen and CO Boiler
Bypass stack and the SO: and NOx at the WGS includes redundant, independent CEMS that can be
activated by the analyzer technicians within a few hours.
CEMS span exceedances are listed in Type Code 210. As described above, the Sulfur Recovery Unit
(SRU) SO: and Flare Total Sulfur (TS) CEMS for the North, South and SRU Flares are comprised of two
or three methods (low, mid, and high) to monitor the full range of expected concentrations to the
analyzers. Therefore, with respect to evaluating CEMS span exceedances, Tesoro does not believe the
entire CEMS span was exceeded if the span was exceeded on just the analyzer's lower methods, and that
it does not qualifo as a span exceedance to be reported under Type Code 210. When the concentration of
the flare gas exceeds the span of the analyzer's low and/or mid methods, it is captured by the analyzer's
high method. With this cascading system on these CEMS, Tesoro can monitor and record the
concentration of the gas up to the high-level span of the analyzer's high method.
Similarly, for evaluation of monitor downtime under Type Code 220 for the flare analyzers, if the gas
concentration was measured in the range of a low, middle, and/or high method, and a daily calibration
failed for that particular method, Tesoro only reported the downtime for the method that failed. For
example, if the flare gas concentration was measured to be only in the low method and a daily calibration
failed for the high method, downtime would only be reported for the high method. For the SRU SOz
analyzers, the high range encompasses the entirety of the low range analyzer. If the low range analyzer
fails a daily calibration while the high range analyzer passes, there will be no downtime.
For the third quarter, all Cylinder Cas Audits (CGAs) are presented in Type Code 260. The North Flare
Total Sulfur analyzers did not complete a CGA during the third quarter. A detailed write up on these
missing CGAs can be found in Appendix A. Relative Accuracy Test Audit (RATA) reports are presented
in Type Code 250.
For the CO Boiler Bypass, a RATA can only be performed on the CO CEMS during certain operating
instances because this analyzer can be operated above span during normal operation and is maintained
through a routine CGA. If the bypass stack were to be utilized, Operations would shift the FCCU to full
burn mode resulting in CO within range of the CEMS.
The Sulfur Recovery Unit (SRU) operates an incinerator for control of reduced sulfur HAPs. Tesoro's
continuous compliance demonstration requirements for the SRU are specified in Subpart UUU Appendix
Table 35, Item 3 (Option 2) and require that the daily average oxygen concentration in the vent stream
must not fall below the level established during the performance test. Tesoro reports exceedances of this
O: limit and O: monitor availability and performance specification results in this report.
Excess Emissions and Out of Control Periods
Flares
Under New Source Performance Standard (NSPS) Ja the North, South and SRU flares are each subject to
the work practice standard to conduct a root cause analysis and corrective action analysis anytime the SOz
emissions exceed 500 lb or discharge to the flare is in excess of 500,000 standard cubic feet (scl; above
an established baseline in a 24-hour period. At each flare location the TS CEMS are used as a surrogate
for SO: emissions. The North and South flare networks are connected to flare gas recovery; therefore,
compliance with the SO: and flow work practice standards is demonstrated on a combined basis (North
plus South). The SO: and flow standards are work practice standards under NSPS Ja and are not emission
limits. As a result, Tesoro does not report SO: and flow as excess emissions in this repoft. Root cause
and corrective actions are reported in the NSPS, Subpart Ja semi-annual report. The SRU Flare uses
Total Sulfur analyzers to demonstrate compliance with Tesoro's 162 ppm 3-hour average H:S limit, while
the North and South Flares use an H2S analyzer to do so. Tesoro has evaluated compliance with HzS with
respect to excess emissions exceeding 162 ppmv on a 3-hour rolling average under Type Code 430. There
was I instance of excess emissions totaling 4 hours for the North Flare H:S for this reporting period.
FCCU WGS
Tesoro has evaluated compliance with SO: with respect to excess emissions exceeding 50 ppmvd at 0%
O: on a 7-day rolling average, per $60.102a(b)(3), and 18 ppmvd at0o/oOton a7-day rolling average, per
ApprovalOrder Condition II.B.4.a under Type Code 410. There were no instances of excess SOz
emissions for this reporting period.
Tesoro has evaluated compliance with NOx with respect to excess emissions exceeding 80 ppmvd at 0%
O: on a 7-day rolling average, per $60.102a(bX2), and 20 ppmvd at lYo Oz on a 7-day rolling average, per
Approval Order Condition ll.B.4.a under Type Code 420. There were no instances of excess NOx
emissions for this reporting period.
Tesoro has evaluated compliance with CO with respect to excess ernissions exceeding 500 ppmvd at 0%
O: on a l-hour rolling average, per $60.102a(b)(4). under Type Code 440. There were 2 instances of
excess CO emissions for this reporting period.
In accordance with Condition ll.B.4.a of the refinery's ApprovalOrder. emissions associated with startup,
shutdorvn, and malfunction of the FCCU and associated SO: and NOx control equipment are not used in
determining compliance with the 7-day emissions limits and are not exceedances of those emissions
limits. In accordance with Condition II.B.4.d of the refinery's Approval Order, emissions from these
periods are not used in determining compliance with the short-term CO emissions limit and are not
exceedances of the emissions limit.

APPENDIX A
The SLC Tesoro refinery operates two independent sulfur species Continuous Emissions Monitoring
Systems (CEMS) on the North Flare: H:S and total sulfur. Both CEMS are subject to the requirements
of 40 CFR 60 rather than the requirements of 40 CFR 75. Based on process knowledge and monitoring
history, it is believed that the preponderance of sulfur present in the North Flare gas stream exists as
HuS. The purpose of the H:S CEMS is to monitor compliance with the 162 ppm operations standard
found in 40 CFR 60.103a(h). The purpose of the total sulfur analyzer is to determine when the refinery
triggers the root cause analysis work practice standard of 500 pounds per hour SOz found in 40 CFR
60.103a(cX1Xi).
During the third quarter 2024 (3Q24) reporting period, a Relative Accuracy Test Audit (RATA) was
required on the H:S CEMS and was successfully completed on812112024. A3Q24 Calibration Gas
Audit (CGA) was also required on the total sulfur analyzel howeveq the CGA was not performed until
October 11,2024. While Tesoro acknowledges the importance of fulfilling all regulatory requirements,
it is noteworthy that this analyzer exists to monitor the triggering of a root cause analysis work practice
standard, rather than monitoring compliance with an emissions limit. During the 3Q24 reporting period,
the highest reported SOz em issions monitored at the north flare were 140. I pounds per day, versus the
trigger for a root cause analysis work practice standard of 500 pounds per day. The refinery has not
triggered a 500 pounds per day root cause analysis work practice standard since January of 2017.
Additionally, Tesoro has not missed a required CGA in at least twenty years. While Tesoro takes the
requirement to perform all required CEMS quality assurance activities seriously, we do not believe any
actual harm to the environment has occurred as a result of this missed requirement. 40 CFR 60 does
not specifo any data validation ramifications of a missed CGA; monitor availability is reported in
accordance with 40 CFR 60 requirements in the attached report.
Several factors combined to result in the missed CGA. Tesoro schedules CGAs using an SAP-based
maintenance work order system. Tesoro maintenance schedulers recently refined how the system
schedules CGAs by scheduling them earlier each quarter, to avoid issues performing them toward the
end of the quarter. During this process, they inadvertently typed an incorrect date into the SAP-based
maintenance work order system. Additionally, during this period the analyzer maintenance team was
operating with an open role and did not notice the unscheduled CGA. Furthermore, the environmental
department was also operating with an open role during this time, and did not notice the missed
requirement until October 10,2024. Once noticed, the environmental department immediately notified
the analyzer team who performed a passing CGA on October 11,2024. Tesoro then notified the Utah
Division of Air Quality on October 15,2024.
The SAP scheduling error has been corrected. Also, the environmental department has backfilled the
open CEMS role and has implemented double checks to ensure that all required CGAs and RATAs are
performed each quarter. Tesoro will continue to commit to improving our operating systems,
minimizing the likelihood of a recurrence.
