barr.com 170 South Main Street, Suite 500, Salt Lake City, UT 84101 | 801.333.8400 Technical Memorandum To: Ethan Upton, Division of Waste Management and Radiation Control From: Guy Partch and Christy Miller, Barr Engineering Co. Subject: Groundwater Monitoring Well Abandonments and Replacements at the Big West Oil North Salt Lake Refinery in 2023-2024 Date: January 27, 2025 c: Jesse Bunkers, Big West Oil Ian Muller, Big West Oil Leigh Beam, Johnston Leigh, Inc. In 2023, Big West Oil, LLC (BWO) coordinated with the Utah Division of Waste Management and Radiation Control (DWMRC) to gain approval for the removal of fourteen (14) groundwater monitoring wells to facilitate several construction projects at BWO’s North Salt Lake (NSL) refinery. Several of these wells were either damaged, not in use, or determined to be unnecessary to monitor groundwater conditions at the perimeter of the refinery. It was agreed that nine (9) monitoring wells would be replaced (new wells installed) upon completion of construction activities. Initial approval from DWMRC for the well abandonments and replacements was received on May 25, 2023. A modification to the installation procedures outlined in the 2019 Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) Phase II Work Plan was requested to require soil screening during well installation with only a photoionization detector (PID) and not both a PID and a laser-induced fluorescence (LIF) tool. Approvals of this modification were received on June 16, 2023 (Access Road wells) and June 20, 2023 (Refinery Projects wells). Lastly, approval was received on December 6, 2023 to adjust the locations of two replacement wells (S-7 and T-24) due to post- construction ground conditions. DWMRC approval communications are included as Attachment A. Following is a list of the wells affected by this effort: • BKW-7 (abandoned and replaced with BKW-7R) • BKW-8 (abandoned and replaced with BKW-8R) • BKW-9 (abandoned and replaced with BKW-9R) • H-6 (abandoned) • S-2 (abandoned) • S-3 (abandoned) • S-5 (abandoned) • S-7 (abandoned and replaced with S-7R) • T-15 (abandoned) • T-20 (abandoned and replaced with T-20R) • T-22 (abandoned and replaced with T-22R) • T-23 (abandoned and replaced with T-23 R) To: Ethan Upton – DWMRC From: Guy Partch, Christy Miller – Barr Engineering Co. Subject: Groundwater Monitoring Well Abandonments and Replacements at the BWO NSL Refinery Date: January 27, 2025 Page: 2 • T-24 (abandoned and replaced with T-24R) • T-25 (abandoned and replaced with T-25R) Project areas and well locations are shown on the attached Figure 1. E.T. Technologies, Inc. (ET) was contracted to perform the work. Prior to well abandonments, a utility locate was performed through Blue Stakes of Utah 811. Due to field conditions, well abandonments occurred in two phases. Wells BKW-8, BKW-7, T-22, T-23, S-2, T-20, H-6, T-15, S-3, and S-7 were abandoned in May 2023. Wells T-24, T-25, and BKW-09 were abandoned in June 2023. All well materials, including the steel protective top, well casing, and screen were removed from the ground and disposed of by ET. Due to the location of well S-5 beneath a propane storage tank, bentonite was used to abandon the well in-place without removing the screen, casing, or protective top. In December 2023, a geophysical survey was performed by Earth Measurement Corp. (EMC) to confirm that there were no buried utilities at the nine proposed replacement well locations. EMC used a ground penetrating radar, an electromagnetic meter, and a radio detection instrument to survey a 20 x 20-foot area centered on each proposed well location. All nine locations were cleared. Documentation of this survey is included in Attachment B. Prior to each well replacement a local utility locate was performed using Blue Stakes of Utah 811. Due to field conditions, well replacements occurred in two phases. Wells BKW-7R, BKW-8R, S-7R, T-22R, T- 23R, and T-24R were installed in January 2024. Wells BKW-9R, T-20R, and T-25R were installed in August 2024. Due to construction activities near T-25R after the geophysical survey, the top eight feet of soil (6-inch diameter) was removed by hydroexcavation during well construction to confirm that buried utilities were not present at the well location. Monitoring wells were installed by ET using a push-probe rig and in accordance with the approved 2019 RFI Phase II Work Plan. Borings were completed to a depth of 15 feet below ground surface (bgs). Continuous sampling was performed (except the upper eight feet at T-25R) to log soil lithology and screen for contamination (e.g. staining, odor, PID readings). Field observations did not indicate soil contamination. PID readings were all below 5 ppm and these low-level PID readings do not correlate with any field observations or hydrocarbon analytical results to indicate contamination. Monitoring wells were constructed with pre-pack 2-inch diameter, 0.010-inch slotted screen and risers. The well heads are all protected in stovepipe above grade completions. Wells will be developed in 2025 prior to groundwater sampling. Boring/well logs are included as Attachment C. ET decontaminated all drilling equipment between each boring per the RFI Phase II Work Plan. All decontamination water was collected and disposed of within the refinery at the millisecond catalytic cracker sump, and all soil cuttings were collected and stored in a labeled 55-gallon drum and placed in a designated area within the refinery to be disposed of at later time. Soil samples were collected for laboratory analysis from each boring at the ground surface and at an interval where the groundwater table was observed and/or at an interval with the highest PID response. Soil samples were submitted to PACE Analytical for analysis of total solids (Method 2540), hexavalent chromium (wet chemistry, Method 7199), mercury (Method 7471A), metals (ICPMS, Method 6020), To: Ethan Upton – DWMRC From: Guy Partch, Christy Miller – Barr Engineering Co.

BWO is constructing an access road along the south refinery perimeter to provide storage tank access and better traffic safety at the refinery. The Revised Plan provides a list of the ten groundwater wells to be abandoned and replaced to accommodate the construction activities. Based on the Revised Plan, wells H-6, S-3, S-5, and T-15 will be abandoned. Wells BKW-8, BKW-7, T-23, T-22, and T-20 will be relocated a short distance from the original wells. BWO intends to abandon and redrill well S-7 in the same location after pavement has been completed. If S-7 is redrilled in the same location, please ensure the boring is large enough to remove any bentonite installed during well abandonment activities to provide a properly installed and functioning replacement well. Another option would be to relocate S-7 a short distance from the original boring. With consideration of the comment regarding replacement of well S-7, the Revised Plan is approved for implementation. Please notify the Division seven days prior to the start of work at the facility to give Division staff the opportunity to oversight the effort.

The Division approved the request for monitoring well replacement (revised May 16, 2023) at BWO based on accepted procedures outlined in the August 28, 2019, Resource Conservation and Recovery Act Facility Investigation (RFI) Phase II Work Plan. These procedures include the use of a laser-induced fluorescence (LIF) tool and photoionization detector (PID) to guide soils sampling. BWO requests a variance to these procedures to include screening soils using only the PID but continuing to collect soils per the RFI Phase II Work Plan. The requested variance to the monitoring well replacement soil screening procedures related to the refinery access road construction project provides an acceptable soil screening method for the collection of soil samples. Therefore, the Variance Request is approved. If you have any questions, please call Karen Wallner at 385-499-0218. Sincerely, Douglas J.

BWO is constructing an access road along the southwestern refinery perimeter and relocating the Waste Management Warehouse and Boiler House to the west side of the refinery. The Refinery Projects Plan provides a list of the three wells to be abandoned and replaced, to accommodate the construction activities. Based on the Refinery Projects Plan, wells BK-9, T-24, and T-25 will be abandoned and replaced with new wells approximately 30 – 50 feet east (upgradient) of the original locations. The replacement wells will be installed, and soil samples will be collected in accordance with the previously approved Resource Conservation and Recovery Act Facility Investigation (RFI) Phase II Work Plan (August 28, 2019) procedures. However, only a Photoionization Detector (PID) will be used to screen the soils instead of using both a PID and a Laser-Induced Fluorescence (LIF) tool during this project. Use of only a PID will provide an acceptable soil screening method for the collection of soil samples. As the upgradient locations of the replacement wells may provide a more conservative detection location for refinery groundwater impacts, the Refinery Projects Plan is approved for implementation. Please notify the Division seven days prior to the start of work at the facility to give my staff the opportunity to oversight the effort.

BWO is constructing an access road along the south refinery perimeter and relocating the Waste Management Warehouse and Boiler House to the west side of the refinery. BWO is requesting to relocate wells T-24 and S-7 to accommodate future projects on the property. Previously, BWO submitted letters to the Division requesting permission to abandon and replace several groundwater monitoring wells to facilitate construction of these projects. The Division approved the abandonment and replacement of these wells in letters dated May 25, 2023, and June 20, 2023. However, due to changes in the design of future potential projects, BWO has requested an adjustment in the location of wells T-24 and S-7. The new proposed location of T-24 is within 10 feet of the original T-24 well location and appears to represent groundwater from the area of the original T-24 location. S-7 is a cross gradient perimeter well located on the east side of the refinery. The new proposed location of S-7 is approximately 250 feet to the southwest of the former S-7 location and is 30 feet north and 150 feet east of the southern refinery fence line. This proposed location for S-7 will allow for the detection of the groundwater benzene plume before it reaches the refinery property limits. (Over) Based on the information contained in the Request, the Request is hereby approved for implementation. Please notify the Division seven days prior to the start of work at the facility to give my staff the opportunity to oversight the effort.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S)Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1701865 02/21/24 08:20 83 of 87 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1701865 02/21/24 15:46 83 of 87 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1701865 02/21/24 08:20 84 of 87 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1701865 02/21/24 15:46 84 of 87 ANALYTICAL REPORT September 03, 2024 Barr Engineering, Inc.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. V The sample concentration is too high to evaluate accurate spike recoveries. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1768597 09/03/24 22:31 88 of 91 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1768597 09/04/24 07:13 88 of 91 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1768597 09/03/24 22:31 89 of 91 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Barr Engineering, Inc.44/06-1025 L1768597 09/04/24 07:13 89 of 91
