The RA of the CEMS shall be no greater than 20 percent of the mean Value of the RM test data in terms of the units of the emission standard or 10 percent of the applicable standard whichever is greater. Stack Test Deviation Report No deviations were observed during testing. DEVIATIONS: No deviations were noted in this report. 1 8 2 2 CONCLUSION: Silver Eagle Refining operates the continuous emissions monitor (CEM) on the Refinery Fuel Gas System to measure H2S emissions. The CEM was audited by the DAQ and found to meet quality assurance requirements found in 40 CFR Part 60, Appendix B, Performance Specification 1, and R307-170, Continuous Emission Monitoring System Program. Quarterly cylinder gas audits and an annual relative accuracy test audit were conducted in accordance with the procedures outlined in UAC R307-170. RECOMMENDATION: The Silver Eagle Refining H2S CEM systems were operating as required in R307-170 and 40 CFR 60.13 at the time of this evaluation.

Portions of the facility are subject to provisions of the 40 CFR 60, Appendix B, PS 7, Subpart J, and the Utah Department of Environmental Quality, Division of Air Quality (UDAQ) Approval Order (AO) DAQE-AN101240030-16. PS testing included conducting a relative accuracy test audit (RATA) to determine the relative accuracy (RA) of the hydrogen sulfide (HzS) continuous emissions monitoring system (CEMS) serving the Fuel Gas and Flare Gas. l.l Process/ControlSystemDescriptions Silver Eagle owns and operates a continuous monitoring system located downstream of the primary fuel mixing drum to determine compliance with the sulfur dioxide (SO) and HzS limits of NSPS Subpart J. The facility records the output of the system, for measuring the HzS concentration in the plant fuel gas. SOz emissions are calculated assuming 100% of the HzS in the plant fuel gas is combusted forming SOz at a ratio of 34lbs of HzS equals 64lbs of SOz. 1.2 CEMS Descriptions Parameter: Make: Model: Serial No.: Span: 1.3 Project Team Personnel involved in this project are identified in the following table.

Method descriptions are provided below while quality assurance/quality control data is provided in Appendix C. Table 3-l: Source Testing Methodology 3.1 U.S. EPA Reference Test Method ll - Hydrogen Sulfide The hydrogen sulfide (HzS) testing was conducted in accordance with U.S. EPA Reference Test Method ll. The complete sampling system consisted of a Teflon probe, five (5) midget impingers, dry gas meter, and pump. The first impinger contained 15 mL of hydrogen peroxide (HzOz), the second impinger was empty and the third, fourth and fifth impingers contained 15 mL of cadmium sulfate (CdSOr). Before and after each test run, the sampling system was leak checked. Following each test run, the sampling train was connected to a charcoal tube and the system was purged with ambient air for 15 minutes to ensure that all HzS is removed from the HzOz The contents of the first impinger were discarded. An acidified iodine (Iz) solution was added to each impinger and these contents were transferred to an iodine flask. The sample analysis was performed onsite by titrating the sample with 0.01 N sodium thiosulfate until the solution tumed a light-yellow color. At this point four (4) mL of starch indicator solution was added to the sample and was repeated until the sample returned to a colorless state. The titrant volumes for the endpoints were recorded and used in the emission calculations. The relative accuracy of the HzS CEMS was determined based on procedures found in 40 CFR 60, Appendix B, Performance Specification 7.
