Testing was performed August 27, 2024, to demonstrate compliance with the CO limits found in 40 CFR Part 63, subpart ZZZZ to reduce CO emissions by 70 percent or more. The source demonstrated compliance by measuring CO emissions at the inlet and outlet of the catalyst. The calculated test results are: Source Test Date Pollutant Method Tester Results Tester Reduction Results DAQ Results DAQ Reduction Results Limits 600 hp Diesel-Fired Generator #62-2180 Inlet August 27, 2024 CO 10 539.2 ppm @ 15% O2 99.6% Reduction 528.33 ppm @ 15% O2 99.6% Reduction 70% or greater CO Reduction 600 hp Diesel-Fired Generator #62-2180 Outlet August 27, 2024 CO 10 2.1 ppm @ 15% O2 1.77 ppm @ 15% O2 DEVIATIONS: None. CONCLUSION: The stack test appears to be acceptable. RECOMMENDATION: The emissions from the one (1) 600 hp diesel-fired generator should be considered to have been in compliance with the emission limits of 40 CFR Part 63, subpart ZZZZ during testing.

The test was conducted to determine compliance with Approval Order DAQE- AN130390005-22 issued by Utah Department of Environmental Quality (UDEQ) as well as 40 CFR Part 63, Subpart ZZZZ requirements. The Environmental Protection Agency has established national emissions limitations and operating limitations for hazardous air pollutants (HAPs) emitted from stationary reciprocating internal combustion engines (RICE) located at major and area sources of HAP emissions. In the Code of Federal Regulations (CFR) Title 40, Part 63, Subpart ZZZZ requires that CO meet one of the following requirements for non- emergency, non-black start compression ignition RICE >600 HP (located in Table 2d.3.): x Limit concentration of CO in the stationary RICE exhaust to 23 ppmvd at 15 percent O2. x Reduce CO emissions by 70 percent or more. The specific objectives were to: x Measure emissions concentrations of O2 and CO at the inlet to the catalyst and the outlet of the catalyst of the Caterpillar SR4B generator engine (#62-2180). x Conduct the test program with a focus on safety. Montrose performed the tests to measure the emission parameters listed in Table 1-1. 5 of 58 GP081AS-042615-RT-1705 Geneva Rock Products, Bauer Pit, 600 hp Diesel-Fired Generator Engine #62-2180, Tooele, Utah2024 Compliance Source Test Report, 40 CFR 63, Subpart ZZZZ Table 1-1 Summary of Test Program Test Date Unit ID/ Source Name Activity/Parameters Test Methods No. of Runs Duration (Minutes) 8/27/2024 600 hp diesel-fired Generator Engine (#62- 2180)1 O2 EPA M3A 3 60 CO EPA M10 3 60 To simplify this report, a list of Units and Abbreviations is included in Appendix C.1.

Typically packaged with the engine muffler, DOCs are widely used as a retrofit technology because they require little or no maintenance. DOCs consist of a flow-through honeycomb structure that is coated with a precious metal catalyst and surrounded by a stainless-steel housing. As hot diesel exhaust flows through the honeycomb (or substrate), the precious metal coating causes a catalytic reaction that breaks down the pollutants. These devices may be formulated to operate with fuel sulfur levels of 500 ppm or less, but they are most effective when fuel sulfur is 15 ppm or less. DOCs can be coupled with closed crankcase ventilation, selective catalytic reduction, or lean NOX catalyst technologies for additional emission reductions. 2.2 Flue Gas Sampling Location Information regarding the sampling location is presented in Table 2-1.

The typical sampling system, which incorporates EPA Method 10, is detailed in Figure 3-1. 3.1.2 EPA Method 10, Determination of Carbon Monoxide Emissions from Stationary Sources (Instrumental Analyzer Procedure) EPA Method 10 is an instrumental test method used to continuously measure emissions of CO. Conditioned gas is sent to a gas filter correlation NDIR analyzer to measure the concentration of CO. The performance requirements of the method must be met to validate the data. Pertinent information regarding the performance of the method is presented below: o Single-point sampling is performed for CO measurements as the inside diameter of each location is too small to conduct a meaningful stratification test as outlined in the provisions in section 8.1.2 of Method 7E. o The expected calibration span values are 511 ppmvd CO for the pre- catalyst sampling location and 50.2 ppmvd CO for the post-catalyst sampling location.
