The CPT was conducted to demonstrate compliance with the performance and emissions requirements of 40 CFR 63, Subpart EEE – National Emission Standards for Hazardous Air Pollutants (NESHAP) from Hazardous Waste Combustors (HWC), a.k.a., the HWC Maximum Achievable Control Technology (MACT) rule. The CPT data were used to establish operating parameter limits (OPLs) to assure continuing compliant operation. The established OPLs included a mercury feed rate limit. This mercury feed rate limit, lower than the previous limit based on the October 2017 CPT, hinders treatment of certain customer waste streams and is generally limiting daily incinerator operations. Clean Harbors has concluded retesting of mercury emissions is necessary to establish a higher mercury feed rate limit. Based on test results, a revised Notification of Compliance (NOC) will be submitted to the Utah Department of Environmental Quality, Division of Air Quality (UDAQ) establishing a new higher mercury feed rate limit and associated mercury emission related OPLs. The supplemental mercury emissions test operating data will be reconciled with the current OPLs established by the May 2023 CPT in accordance with 40 CFR 63.1209(i): (i) When an operating parameter is applicable to multiple standards. Paragraphs (j) through (p) of this section require you to establish limits on operating parameters based on comprehensive performance testing to ensure you maintain compliance with the emission standards of this subpart. For several parameters, you must establish a limit for the parameter to ensure compliance with more than one emission standard. An example is a limit on minimum combustion chamber temperature to ensure compliance with both the DRE standard of paragraph (j) of this section and the dioxin/furan standard of paragraph (k) of this section. If the performance tests for such standards are not performed simultaneously, the most stringent limit for a parameter derived from independent performance tests applies. This test plan delineates the incinerator system operational targets, sampling and analyses, and test data reduction and reporting. This test plan is being submitted at least 60 days prior to the planned test date of November 15, 2024. 1.2 SITE CONTACT Questions and comments regarding this test plan should be addressed to: Mr. Kenneth Banks Senior Environmental Compliance Manager Clean Harbors Aragonite, LLC (435) 884-8233 E-mail: banks.kenneth@cleanharbors.com.

The emissions samples will be analyzed by the Eurofins Environment Testing (Eurofins), Knoxville, Tennessee laboratory. Focus Environmental, Inc. (Focus) will be responsible for coordination and overall management of the test program. Clean Harbors Aragonite, LLC Mercury Emissions Test Plan Revision 1, October 2024 CH-UT Hg Test Plan 2024 Rev 1 18-Oct-24.docx 3 Print Date: 18-Oct-24 Project No. P-001591 2.0 PLANNED TEST PROTOCOL 2.1 CURRENT AND PREVIOUS MERCURY FEED RATE LIMITS The current OPLs from the August 2, 2023 Notification of Compliance (NOC) are summarized in Table 1. (Note: Table 1 is the same as Table 3 from the August 2, 2023 NOC.) The current mercury feed rate limit established by the May 2023 CPT is 0.615 lb/hr. As presented in Table 2, this value is based on an average CPT feed rate 0.122 lb/hr extrapolated to the emission standard of 130 ug/dscm @ 7% O2. (Note: Table 2 is an excerpt of Table 4 from the August 2, 2023 NOC.) The previous mercury feed rate was 1.29 lb/hr similarly derived based on the October 2017 CPT data. 2.2 MERCURY RETESTING OBJECTIVES Clean Harbors plans to conduct testing to establish a higher mercury feed rate limit. Testing will be conducted as three (3) test runs feeding customer waste and spiking mercury to the waste feed. The test data will be used to establish a new mercury feed rate limit and 40 CFR 63.1209(i) reconciled values for the following mercury emissions related OPLs:  Maximum Stack Flow Rate 40 CFR 63.1209(l)(2)  Minimum Activated Carbon Feed Rate 40 CFR 63.1209(l)(3)  Minimum First Stage Scrubber Flow Rate 40 CFR 63.1209(l)(2)  Minimum First Stage Scrubber Flow Rate 40 CFR 63.1209(l)(2)  Minimum TMT-15 Feed Rate [mercury emissions control additive not specifically addressed by 40 CFR 63.1209(l)]  Minimum First Stage Scrubber Differential Pressure 40 CFR 63.1209(l)(2)  Minimum Second Stage Scrubber Differential Pressure 40 CFR 63.1209(l)(2) The following additional mercury emissions related OPLs are set based on manufacturer’s specifications independent of test operating conditions and will not be changed by the planned testing:  Minimum Activated Carbon Carrier Fluid Flow Rate 40 CFR 63.1209(l)(3)  Minimum Low Energy Scrubber Differential Pressure 40 CFR 63.1209(l)(2)  Minimum Low Energy Scrubber Liquid Feed Pressure 40 CFR 63.1209(l)(2) The new mercury feed rate limit will be established based on extrapolation of the test demonstrated feed rate and resulting emissions using the following equation: 𝐹𝑅ு௚ ൌ 𝐹𝑅்௘௦௧ ൈ 𝐸𝑆 𝐸𝐶்௘௦௧ Clean Harbors Aragonite, LLC Mercury Emissions Test Plan Revision 1, October 2024 CH-UT Hg Test Plan 2024 Rev 1 18-Oct-24.docx 4 Print Date: 18-Oct-24 Project No. P-001591 where: FRHg = Maximum allowable feed rate limit of mercury FRTest = Feed rate of mercury demonstrated during the test ES = HWC NESHAP emissions standard for mercury, ECTest = Emissions concentration of mercury demonstrated during the test 2.3 TARGET OPERATING CONDITIONS The mercury test target operating conditions are summarized in Table 3. Test targets are proposed for the mercury emissions related OPLs. No targets are proposed for OPLs that are not mercury emissions related. Targets for the mercury emissions related OPLs are at or above the current limits for maximums and at or below current minimums. To conduct testing will require deactivating automatic waste cutoffs (AWFCO) for OPLs that may be exceeded during testing. Request to do so is in accordance with 40 CFR 63.1207(h)(1): (h) Operating conditions during subsequent testing. (1) Current operating parameter limits established under §63.1209 are waived during subsequent comprehensive performance testing. Approval of this test plan by UDAQ will constitute approval to bypass AWFCO limits accordingly during ramp up to test conditions, shakedown operation, and through completion of testing. 2.4 SAMPLING AND ANALYSES Table 4 summarizes sampling and analyses to be performed during testing. 2.4.1 Native Mercury Feed Rate Documentation The native mercury feed rate will be documented based on the customer supplied analysis data and on- site laboratory waste analyses as programmed into, tracked, and recorded by the incinerator’s data acquisition system (DAS). The native mercury feed rate is expected to be substantially less than the spiked mercury feed rate. 2.4.2 Spiked Mercury Feed Rate Documentation The HWC MACT mercury feed rate limit is a total mercury feed limit. Mercury spiking materials will be prepared as pre-weighed packages (Ziplock® bags or comparable) of mercury (II) oxide [HgO]. This is the same chemical and method used to spike mercury during the May 2023 CPT. The mercury spikes will be placed on (piggy backed on) packages or containers of customer waste and fed at regular intervals. The spiked mercury feed rate will be based on the waste package or container drop times, prepared bag weights, and supplier’s chemical assay.

Clean Harbors anticipates that the test will be performed in a single day over a period of approximately ten (10) hours. This includes one 1.5 hours of operation at test target conditions including mercury spiking (system conditioning), three 2- hour sampling runs, plus time for port changes and turnaround time between test runs. If there is a waste feed interruption, the following guidelines will be followed:  Emissions sampling will be stopped as quickly as possible after the interruption.  If the interruption is less than five minutes, there will be no line out period, and testing will recommence as soon as possible.  If the interruption is between five and 20 minutes, there will be a 15-minute line out period, and then sampling will recommence.  If the interruption is between 20 and 60 minutes, there will be a 30-minute line out period and sampling will recommence.  If the interruption exceeds 60 minutes, there will be a one-hour line out period. The test report results will be submitted to the following agencies within 60 days after completion of the field test program:  Utah Department of Environmental Quality, Division of Air Quality (UDAQ); and  Utah Department of Environmental Quality, Division of Waste Management and Radiation Control (UDWMRC). The report will include summaries of the test results, discussions of any instances where the test plan or any specified methods were not followed, discussion of the impact of any deviations on the test results or determinations. The spiked mercury feed rate will be calculated as described previously in Section 2.4.2. For the purposes of calculating the native mercury feed rates, zero will be used where waste feed analysis results are reported as not present at detectable levels. For the purposes of calculating mercury emissions, the reporting limit will be used where analysis results are reported as not present at detectable levels. The test report will include:  Test Program Summary  Results Overview  Process Operating Conditions  Results of Sample Analyses  Example Calculations  Established Operating Parameter Limits.
