RMEC PJ25E-5051 April 15, 2025 Woodrow “Woody” Campbell Environmental Engineer Utah Department of Environmental Quality Division of Water Quality – Groundwater Protection Section 195 North 1950 West Salt Lake City, Utah 84114-3100 SUBJECT: APPLICATION FOR GROUNDWATER DISCHARGE PERMIT RE: PROJECT ROCKY / SLC GLC LOT 11 7026 W. 700 North Salt Lake City, Utah 84116 Dear Woody: On behalf of Supply Properties II, LLC (“Applicant”), RMEC Environmental, Inc. (RMEC) is hereby providing the Utah Department of Environmental Quality (DEQ) Division of Water Quality (DWQ) Groundwater Protection Section with a Groundwater Discharge Permit application associated with the above-referenced commercial property in Salt Lake City. RMEC is serving as the environmental consultant and permitting representative for the Applicant in this matter. Project Site Description The Project Rocky / SLC GLC Lot 11 property is a vacant, 11.905-acre lot that was recently acquired from SLC Port Phase 1A, LLC, a subsidiary of NWQ, LLC. Current construction plans include the development of a freezer warehouse and distribution center. Under the previous ownership, this project site had been designated as Lot 11 of the Salt Lake City (SLC) Port Global Logistics Center (GLC) (collectively, “SLC Port GLC”) Project Site, a large tract of land on the north side of 700 North Street and between 6100 West and 7200 West. Individual lots within SLC Port GLC have slowly been developed since 2019—developments initially began in the eastern portion of the tract and have generally progressed to the west. See Figures 1 and 2, enclosed. Permitting Background In February 2023, DWQ migrated the entire SLC Port GLC Project Site from coverage under the General Permit for Treated Groundwater under Utah Pollution Discharge Elimination System (UPDES) Permit No. UTG790000 for large-scale construction work to a Permit under Groundwater rules (“Permit-by-Rule Determination”) in accordance with Utah Administrative Code (UAC) R317-6. This was primarily due to the preferred practice of land application for all construction dewatering. Refer to DEQ document “DWQ- 2023-002169” (not enclosed) for additional details. Now that the project site is under separate ownership, the Applicant is seeking to acquire and maintain its own groundwater permit prior to the forthcoming construction work that is expected to involve groundwater dewatering. Similar to nearby construction work in the SLC Port GLC Project Site, the preferred dewatering discharge method is land application. Utah Division of Water Quality RMEC PJ25E-5051 Page 2 of 3 April 15, 2025 Description of Construction Activities and Discharges Excavation dewatering during construction of the proposed freezer warehouse and distribution center is expected during installation of water and sewer lines. In certain locations, utility lines may be installed at a maximum depth of 25 feet below ground surface (bgs) along open-trench excavations. Dewatering would consist of using in-situ electric pumps set at low points within the trenches. The project site is relatively flat and suitable for land application (to prevent runoff) as the primary dewatering control measure. Current construction plans include a retention pond in the eastern portion of the property, which is an ideal location to allow for land application and groundwater reinfiltration. As necessary, that area will be bermed and/or contoured to ensure accumulated water is retained onsite. Refer to the enclosed site map. Other Permitting Considerations It should be noted that in order to prevent construction timeline disruptions, the Applicant is simultaneously applying for a Treated Groundwater Discharge Permit for off-site discharges. While no significant contamination has been detected onsite to date, the project site is adjacent to the former North Temple Landfill (NTL), which is currently engaged with DEQ through the Voluntary Cleanup Program (VCP) due to known soil and groundwater contaminants that have migrated off-site. Application for a Treated Groundwater Permit (rather than a traditional construction dewatering permit) is being completed as a precaution to ensure any potential contaminants in dewatering discharges are appropriately addressed through an approved permitting mechanism. In the event that the preferred land application discharge method is not feasible (e.g., due to proximity issues or other onsite logistical concerns) or not adequate (e.g., insufficient infiltration rates or not enough volume), having the Treated Groundwater Permit in place will allow the construction contractor to pivot from land application practices to treatment and off-site discharges without scheduling disruptions. Analytical Sampling Until recently, analytical sampling on and around the property (due to being part of the larger SLC Port GLC Project Site) has included periodic sampling of land-applied discharges. No significant contamination has been detected during those limited dewatering activities, which have generally been infrequent. During the due diligence period prior to the recent ownership change for Lot 11, site-specific groundwater sampling was conducted, primarily to evaluate potential contaminants migrating from the adjoining former NTL site. Contaminants of concern included metals, volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), methane, pesticides, herbicides, polychlorinated biphenyls (PCBs), and per- and poly-fluoroalkyl substances (PFAS), including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Copies of the site-specific analytical results reports have been attached to this letter. Below is a summary of the relevant results: • Arsenic and PFOAs were detected in groundwater above their respective drinking water Maximum Contaminant Levels (MCLs); however, planned development does not include utilizing groundwater as a drinking water source, and no other drinking water sources are present in the vicinity. Arsenic in groundwater has been attributed to natural (not man-made) sources. The presence of PFAS is attributed to migration from the adjoining former NTL site. RMEC anticipates that any permit coverage issued by DEQ for this property will be similar to the existing permit for the SLC Port GLC Project Site. Based on that assumption, and in accordance with what has been done for the SLC Port GLC Project Site, RMEC intends to manage and provide oversight of the permitted Utah Division of Water Quality RMEC PJ25E-5051 Page 3 of 3 April 15, 2025 activities. This includes collecting periodic analytical samples during excavation dewatering. Unless otherwise required by DWQ, land-applied discharges would be analyzed for the following parameters: ▪ pH ▪ Total Arsenic ▪ Total Lead ▪ Oil and Grease ▪ Volatile Organic Compounds (VOCs) ▪ Total Petroleum Hydrocarbons (TPH) In addition to the above-listed parameters, visual observations (e.g., solids or sheen) or other adverse conditions will be recorded. If test results reveal that any applicable permit parameters have been exceeded, all excavation dewatering involving land application will be ceased and DWQ will be immediately notified. The Applicant would then work with DWQ to pursue any prescribed corrective actions. Reporting and Communication As required, RMEC will assist the Applicant with the completion and submittal of any documents related to the Groundwater Discharge Permit. Also, as mentioned previously, all significant concerns or conditions of noncompliance will be promptly communicated to DWQ. Closing We understand that this permit request is unique and may include provisions and parameters that are atypical. The Applicant is committed to working with DWQ to ensure that the dewatering activities during all construction work are completed under the requirements set forth in the Groundwater Discharge Permit.

If more than one discharge point is used, information for each point must be provided. Hazardous Substances - Review the present hazardous substances found in the Clean Water Act, if applicable. List those substances found or believed present in the discharge or potential discharge. FIBER PREPARATION DYEING WASHING DRYING GRIT SEPARATOR NEUTRALIZATION TANK WASTE TREATMENT PLANT WASTE IMPOUNDMENT (DISCHARGE 2 GDP) Land application 5 Part C - Accompanying Reports and Plans The following reports and plans should be prepared by or under the direction of a professional engineer or other ground water professional. Since ground water permits cover a large variety of discharge activities, the appropriate details and requirements of the following reports and plans will be covered in the pre-design meeting(s). For further instruction refer to the Ground Water Permit Application Guidance Document. 8. Hydrogeologic Report Provide a Geologic Description, with references used, that includes as appropriate: Structural Geology – regional and local, particularly faults, fractures, joints and bedding plane joints; Stratigraphy – geologic formations and thickness, soil types and thickness, depth to bedrock; Topography – provide a USGS MAP (7 ½ minute series) which clearly identifies legal site location boundaries, indicated 100 year flood plain area and applicable flood control or drainage barriers and surrounding land uses. Provide a Hydrologic Description, with references used, that includes: Ground water – depths, flow directions and gradients. Well logs should be included if available. Include name of aquifer, saturated thickness, flow directions, porosity, hydraulic conductivity, and other flow characteristics, hydraulic connection with other aquifers or surface sources, recharge information, water in storage, usage, and the projected aerial extent of the aquifer. Should include projected ground water area of influence affected by the discharge. Provide hydraulic gradient map indicating equal potential head contours and ground water flow lines. Obtain water elevations of nearby wells at the time of the hydrologic investigation. Collect and analyze ground water samples from the uppermost aquifer which underlies the discharge point(s). Historic data can be used if the applicant can demonstrate it meets the requirements contained within this section. Collection points should be hydraulically up and downgradient and within a one-mile radius of the discharge point(s). Ground water analysis should include each element listed in Ground Water Discharge Permit Application, Part B7. NOTE Failure to analyze for background concentrations of any contaminant of concern in the discharge or potential discharge may result in the Executive Secretary’s presumptive determination that zero concentration exist in the background ground water quality. Sample Collection and Analysis Quality assurance – sample collection and Preservation must meet the requirements of the EPA RCRA Technical Enforcement Guidance Document, OSWER-9959.1, 1986 [UAC R317-6-6.3(I,6)]. Sample analysis must be performed by State of Utah certified laboratories and be certified for each of the parameters of concern. Analytical methods should be selected from the following sources [UAC R317-6-6.3L]: (Standard Methods for the Examination of Water and Wastewater, 20th Ed.,1998; EPA, Methods for Chemical Analysis of Water and Wastes, 1983; Techniques of Water Resources Investigation of the U.S. Geological Survey, 1998, Book 9; EPA Methods published pursuant to 40 CFR Parts 141, 142, 264 (including Appendix IX), and 270. Analytical methods selected should also include minimum detection limits below both the Ground Water Quality Standards and the anticipated ground water protection levels. Data shall be presented in accordance of accepted hydrogeolgic standards and practice. Provide Agricultural Description,with references used, that includes: If agricultural crops are grown within legal boundaries of the site the discussion must include: types of crops produced; soil types present; irrigation system; location of livestock confinement areas (existing or abandoned). 6 Note on Protection Levels: After the applicant has defined the quality of the fluid to be discharged (Ground Water Discharge Permit Application, Part B), characterized by the local hydrogeologic conditions and determined background ground water quality (Hydrogeologic Report), the Executive Secretary will determine the applicable ground water class, based on: 1) the location of the discharge point within an area of formally classified ground water, or the background value of total dissolved solids. Accordingly, the Executive Secretary will determine applicable protection levels for each pollutant of concern, based on background concentrations and in accordance with UAC R317-6-4. 9.Ground Water Discharge Control Plan: Select a compliance monitoring method and demonstrate an adequate discharge control system. Listed are some of the Discharge Control Options available. No Discharge – prevent any discharge of fluids to the ground water by lining the discharge point with multiple synthetic and clay liners. Such a system would be designed, constructed, and operated to prevent any release of fluids during both the active life and any post-closure period required. Earthen Liner – control the volume and rate of effluent seepage by lining the discharge point with a low permeability earthen liner (e.g. clay). Then demonstrate that the receiving ground water, at a point as close as practical to the discharge point, does not or will not exceed the applicable class TDS limits and protection levels* set by the Executive Secretary. This demonstration should also be based on numerical or analytical saturated or unsaturated ground water flow and contaminant transport simulations. Effluent Pretreatment – demonstrate that the quality of the raw or treated effluent at the point of discharge or potential discharge does not or will not exceed the applicable ground water class TDS limits and protection levels* set by the Executive Secretary. Contaminant Transport/Attenuation – demonstrate that due to subsurface contaminant transport mechanisms at the site, raw or treated effluent does not or will not cause the receiving ground water, at a point as close as possible to the discharge point, to exceed the applicable class TDS limits and protection levels* set by the Executive Secretary. Other Methods – demonstrate by some other method, acceptable to the Executive Secretary, that the ground water class TDS limits and protection levels* will be met by the receiving ground water at a point as close as practical to the discharge point. *If the applicant has or will apply for an alternate concentration limit (ACL), the ACL may apply instead of the class TDS limits and protection levels. Submit a complete set of engineering plans and specifications relating to the construction, modification, and operation of the discharge point or system. Construction Permits for the following types of facilities will satisfy these requirements. They include: municipal waste lagoons; municipal sludge storage and on-site sludge disposal; land application of wastewater effluent; heap leach facilities; other process wastewater treatment equipment or systems. Facilities such as storage piles, surface impoundments and landfills must submit engineering plans and specifications for the initial construction or any modification of the facility. This will include the design data and description of the leachate detection, collection and removal system design and construction. Provide provisions for run on and run-off control. 7 10.Compliance Monitoring Plan: The applicant should demonstrate that the method of compliance monitoring selected meets the following requirements: Ground Water Monitoring – that the monitoring wells, springs, drains, etc., meet all of the following criteria: is completed exclusively in the same uppermost aquifer that underlies the discharge point(s) and is intercepted by the upgradient background monitoring well; is located hydrologically downgradient of the discharge point(s); designed, constructed, and operated for optimal detection (this will require a hydrogeologic characterization of the area circumscribed by the background sampling point, discharge point and compliance monitoring points); is not located within the radius of influence of any beneficial use public or private water supply; sampling parameters, collection, preservation, and analysis should be the same as background sampling point; ground water flow direction and gradient, background quality at the site, and the quality of the ground water at the compliance monitoring point. Source Monitoring – must provide early warning of a potential violation of ground water protection levels, and/or class TDS limits and be as or more reliable, effective, and determinate than a viable ground water monitoring network. Vadose Zone Monitoring Requirements – Should be: used in conjunction with source monitoring; include sampling for all the parameters required for background ground water quality monitoring; the application, design, construction, operation, and maintainence of the monitoring system should conform with the guidelines found in: Vadose Zone Monitoring for Hazardous Waste Sites; June 1983, KT-82- 018(R). Leak Detection Monitoring Requirements – Should not allow any leakage to escape undetected that may cause the receiving ground water the exceed applicable ground water protection levels during the active life and any required post-closure care period of the discharge point. This demonstration may be accomplished through the use of numeric or analytic, saturated or unsaturated, ground water flow or contaminant transport simulations, using actual filed data or conservative assumptions. Provide plans for daily observation or continuous monitoring of the observation sump or other monitoring point and for the reporting of any fluid detected and chemical analysis thereof. Specific Requirements for Other Methods – Demonstrate that: the method is as or more reliable, effective, and determinate than a vable ground water monitoring well network at detecting any violation of ground water protection levels or class TDS limits, that may be caused by the discharge or potential discharge; the method will provide early warning of a potential violation of ground water protection levels or class TDS limits and meets or exceeds the requirements for vadose zone or leak detection monitoring. Monitoring well construction and ground water sampling should conform to A Guide to the Selection of Materials for Monitoring Well Construction. Sample collection and preservation, should conform to the EPA RCRA Technical Enforcement Guidance Document, OSWER-9950.1, September, 1986. Sample analysis must be performed by State-certified laboratories by methods outlined in UAC R317-6-6.3L. Analytical methods used should have minimum detection levels which meet or are less than both the ground water quality standards and the anticipated protection levels. 8 11. Closure and Post Closure Plan: The purpose of this plan is to prevent ground water contamination after cessation of the discharge or potential discharge and to monitor the discharge or potential discharge point after closure, as necessary. This plan has to include discussion on: liquids or products, soils and sludges; remediation process; the monitoring of the discharge or potential discharge point(s) after closure of the activity. 12. Contingency and Corrective Action Plans: The purpose of this Contingency plan is to outline definitive actions to bring a discharge or potential discharge facility into compliance with the regulations or the permit, should a violation occur. This applies to both new and existing facilities. For existing facilities that may have caused any violations of the Ground Water Quality Standards or class TDS limits as a result of discharges prior to the issuance of the permit, a plan to correct or remedy any contaminated ground water must be included. Contingency Plan – This plan should address: cessation of discharge until the cause of the violation can be repaired or corrected; facility remediation to correct the discharge or violation. Corrective Action Plan – for existing facilities that have already violated Ground Water Quality Standards, this plan should include: a characterization of contaminated ground water; facility remediation proposed or ongoing including timetable for work completion; ground water remediation.

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 B The same analyte is found in the associated blank. C3 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low. Method sensitivity check is acceptable. J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. 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. P RPD between the primary and confirmatory analysis exceeded 40%. Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be considered minimum values. U Below Detectable Limits: Indicates that the analyte was not detected. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Intertek/PSI - Salt Lake City, UT 02792278 L1823920 02/14/25 16:19 57 of 59 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Intertek/PSI - Salt Lake City, UT 02792278 L1823920 02/14/25 16:24 57 of 59 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: Intertek/PSI - Salt Lake City, UT 02792278 L1823920 02/14/25 16:19 58 of 59 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Intertek/PSI - Salt Lake City, UT 02792278 L1823920 02/14/25 16:24 58 of 59 ANALYTICAL REPORT February 13, 2025 Intertek/PSI - Salt Lake City, UT Sample Delivery Group:L1823086 Samples Received:02/05/2025 Project Number: Description:Warehouse-NE Corner of W 700N and W 1400 N Site:SLC, UT Report To:Elliott Rodgers 2779 South 600 West Salt Lake City, UT 84115 Entire Report Reviewed By: February 13, 2025 [Preliminary Report] Jordan N Zito Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as "Total" may vary slightly from the sum of the reported component parameters. Pace Analytical is TNI accredited.

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 C3 The reported concentration is an estimate. The continuing calibration standard associated with this data responded low. Method sensitivity check is acceptable. J4 The associated batch QC was outside the established quality control range for accuracy. 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: Intertek/PSI - Salt Lake City, UT L1830274 02/28/25 15:40 22 of 24 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Intertek/PSI - Salt Lake City, UT L1830274 02/28/25 16:03 22 of 24 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: Intertek/PSI - Salt Lake City, UT L1830274 02/28/25 15:40 23 of 24 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Intertek/PSI - Salt Lake City, UT L1830274 02/28/25 16:03 23 of 24 The analyses presented on this report were performed in accordance with the National Environmental Laboratory Accreditation Program (NELAP) unless noted in the comments, flags, or case narrative.
