No. 1 date March 15, 2023 www.kleinfelder.com 1 EXECUTIVE SUMMARY ___________________________________________________________________________________ 1.1 INTRODUCTION AND SITE DESCRIPTION This report presents the results of a Phase II Site Characterization conducted within the approximate 900-acre Olympia Hills property, located northeast of the intersection of Highway 111 and Butterfield Canyon Road in Salt Lake County, Utah (Site) on behalf of SOJO118, LLC (Client) and a Soils Management Plan for one portion of the Site, the Bastian Ditch Shallow Flood Plain Soils. The purpose of the investigation was to assess for potential lead and arsenic impacts to Site soils from historical waterways (natural and man-made) that are known to have historically carried metals-impacted water and sediment. The investigation included an assessment of whether remnants of the waterway channels remain on Site, characterization of the channel sediments and adjacent shallow soils for the concentrations of lead and arsenic, and assessment of the condition and contents of the Bingham Tunnel irrigation pipeline. The Site location is presented on Figure 1. A topographic map showing the Site boundaries is presented as Figure 2. The Site is approximately 900 acres in size and is owned by the Last Holdout, LLC. It has historically been used for row crop agriculture. The Site contains portions of three Operable Units (OUs) of the Kennecott South Zone CERCLA site; the Bastian Ditch (OU5), Copper Creek (OU6), and Butterfield Creek/Herriman Residential and Agricultural (OU3); each of which carried metals-impacted water and sediment along waterways originating from mining areas west of the Site. The Operable Units are shown on Figure 3. Both natural and manmade water ways have historically crossed the Site, as depicted on Figure 4. Butterfield Creek and Copper Creek are natural drainages that ran from the western mountain range through southern and northern portions of the subject property, respectively. The Bastian Ditch, Bingham Tunnel Pipeline, and Butterfield Ditch were constructed as irrigation systems that traversed the site from north to south or west to east. 1.2 SITE CHARACTERIZATION ACTIVITIES Kleinfelder’s scope of services included a review of historical aerial photographs, identifying the approximate locations of historical waterways, excavation of trenches and test pits in the areas of potential contaminant concern, soil sample collection and laboratory analysis for total lead and arsenic. Figure 5 presents the locations of explorations conducted as part of this investigation. Prior Site 20210351.001A/SLC22R147484_R1 Page 2 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com investigations conducted by Rio Tinto Kennecott Utah Copper (RTKC) and Wasatch Environmental Inc. (Wasatch) are discussed in Section 6 of this report. The Phase II analytical results were compared to soil action levels established for Kennecott South Zone Operable Units OU3, OU5, and OU6 and the Salt Lake County Contaminated Soils Ordinance: • Recreational Land Use Standards - 2,207 mg/kg lead and 283 mg/kg arsenic. • Unrestricted Land Use Standards - 500 mg/kg lead and 50 mg/kg arsenic. The Site is proposed for development as mixed-use residential, commercial, and recreational property. When the Kennecott South Zone land use standards were established for these operable units, the area was open space and agricultural land, therefore no Residential or Commercial Land Use Standards were established at that time. 1.3 FINDINGS Metals-impacted soils were detected at concentrations exceeding the Unrestricted Land Use Standards in each of the areas investigated. In general, the location, depth and lateral extent of impacted soils associated with each waterway was characterized. Findings of this investigation are as follows: • Bastian Ditch (OU5) – Lead and arsenic concentrations in soil exceeding the Unrestricted Land Use Standards were generally limited to the upper 24 inches of soil. The width of channel sediments observed in the trenches ranged from approximately six to ten feet. The alignment of the historical channel is no longer visible on the ground surface. • Copper Creek (OU6) – Lead and arsenic concentrations in soil exceeding the Unrestricted Land Use Standards were generally limited to the upper 4.5 feet of the channel soils but were observed at a depth of ten feet in one location. The width of channel sediments observed in the trenches ranged from approximately 8 to 25 feet. The channel is visible on the ground surface. • Butterfield Creek (OU3) – Lead and arsenic concentrations in soil exceeding the Unrestricted Land Use Standards were identified at depths up to 14 feet below the floor of the drainage. The Creek channel is visible on the ground surface and is approximately 15 feet below the surrounding grade and 50 feet wide on its west side, tapering to three feet deep and ten feet wide on the east end. The segment of Butterfield Creek that crosses the southwest portion of the Site near the Bastian Farm buildings and fields was not assessed during this investigation. Prior assessments and remedial actions have been performed by RTKC in this area. 20210351.001A/SLC22R147484_R1 Page 3 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com • Butterfield Ditch (east-west oriented segment) –Lead and arsenic concentrations in soil along the east-west oriented segments of the Butterfield Ditch alignment were reported below the Unrestricted Land Use Standards. The alignment of the historical Ditch is no longer visible on the ground surface. • Butterfield Ditch (north-south oriented segment) – Lead and arsenic concentrations in soil along the north-south oriented segment of the Butterfield Ditch that exceed the Unrestricted Land Use Standards were generally limited to the upper 6 to 12 inches of soil. The alignment of the historical Ditch is no longer visible on the ground surface. • Ditch Overflow Shallow Soils– Lead and arsenic concentrations in shallow soils east of, and topographically lower than, the Bastian Ditch and/or Butterfield Ditch N-S segment that exceed the Unrestricted Land Use Standards appear to be limited primarily to the upper 6 inches of soil; but were observed up to 12 inches deep in some locations. • Bingham Tunnel Pipeline and Outfall Soils– No significant sediment buildup was observed within the two Bingham Tunnel pipelines. Elevated lead and arsenic concentrations were detected on hard scale scraped from the piping interior in two locations. Standing water was noted in the piping in some locations, while piping in other locations were dry. Lead and Arsenic concentrations in soil exceeded the Unrestricted Land Use Standards at the pipeline south outfall in the upper two to three feet of soil. 20210351.001A/SLC22R147484_R1 Page 4 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 2 INTRODUCTION ___________________________________________________________________________________ 2.1 SCOPE OF SERVICES Kleinfelder has prepared this report to present the results of a Site Characterization conducted within the approximately 900-acre Olympia Hills property located northeast of the intersection of Highway 111 and Butterfield Canyon Road in Salt Lake County and Herriman, Utah (Site) on behalf of SOJO118, LLC (Client). The Site location is presented on Figure 1. A topographic map indicating the Site boundaries is presented as Figure 2. This investigation was conducted to assess the concentrations of lead and arsenic in soil along waterways identified as “areas of concern” by Wasatch Environmental in a Phase I Environmental Site Assessment (ESA) conducted for the Site in 2017; and to comply with Salt Lake County Contaminated Soils Ordinance, Title 9 Chapter 9.5. The “areas of concern” identified in the Phase I ESA are presented on Figure 4. This assessment areas included the Bastian Ditch (OU5), Copper Creek (OU6), Butterfield Creek (OU3), Butterfield Ditch, Bastian Ditch Flood Plain Shallow Soils and the Bingham Tunnel Pipeline. Kleinfelder’s scope of services included a review of historical aerial photographs, identifying the approximate locations of historical waterways, excavation of trenches and test pits, soil sample collection and laboratory analysis for total lead and arsenic. 2.2 SITE HISTORY AND FEATURES The following Site history is excerpted from the Wasatch Phase I ESA: The Site consists of land under agricultural production, with farming-related structures and a residence in the southwest corner of the Site. The area of the subject property has a history of mining impacts and farming dating back well into the 1800s. Historical mining and milling operations that occurred from the 1870s to the 1950s in the mountain range west of the subject property have resulted in lead and arsenic impacts to soil and sulfate impacts to groundwater in the vicinity of the subject property. The historical transport of water containing lead and arsenic contaminated sediment via creeks, ditches and tunnels, that originated in areas of known mine waste deposition, have been utilized by the town of Herriman for irrigation purposes. Butterfield Creek (OU3) and Copper Creek (OU6) ran from the western mountain range through southern and northern portions of the subject property, respectively. Several irrigation systems traversed the subject property including the Bastian Ditch (OU5), the Bingham Tunnel Irrigation Pipeline, and the Butterfield Ditch. 20210351.001A/SLC22R147484_R1 Page 5 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com Based on information provided by RTKC personnel, the Bastian Ditch and Butterfield Ditch were in use from the 1880s to the 1930s. The Bingham Tunnel (an eight-inch transite pipeline) was installed in 1952 to carry water from Kennecott operations to the north, to Butterfield Creek and agricultural land further south in Herriman City. A second ten-inch transite pipe was installed adjacent to the first in 1970. The Bingham Tunnel water flow was diverted to a settling pond on property southeast of the Site, called the Dansie Pond (see Figures 4 and 5). The water in the pond was then diverted to farmland on south and east adjoining properties. The Bingham tunnel (which is not an Operable Unit) was no longer in use by 1988. It traverses the west-central portion of the Site from north to south, for approximately 0.7 miles. The two transite pipelines remain buried on the Site. The historical alignment of the Bastian Ditch (OU5) extends approximately 3,300 feet across the Site from north to south; its alignment is no longer visible on the ground surface. Copper Creek (OU6) crosses the Site in two locations: the northwest corner and the east-central portion of the Site, totaling approximately one mile of waterway. The Copper Creek channel is incised on the northwest portion of the Site, but no longer discernible on the ground surface on the northeast portion of the Site. Butterfield Creek (OU3) crosses the Site in two locations: its southwest corner and southeast corner, totaling approximately 1.2 miles of creek channel. At the southwest location, near the Bastian Farm fields, the Creek’s original alignment has been buried and the Butterfield Creek water diverted into an irrigation ditch (also called Butterfield Creek). In the southeast section the original, incised Creek channel is still visible. The historical Butterfield Ditch (which is not an Operable Unit) reportedly began near the southern extent of the Bingham Tunnel and traversed east for approximately 1.2 miles, then turned north for 0.25 miles, and east again following the Site’s northern property line for another 0.4 miles before turning north/off-site. There is no surface evidence of the Butterfield Ditch alignment. Figure 3 presents the Operable Unit locations with respect to the Site. The waterways are presented on Figure 4. Several prior investigations and remedial actions have been performed at the Site as discussed in Section 6 of this report. The segment of Butterfield Creek near the Bastian Farm buildings and fields (southwest corner) was not assessed during this characterization. Several former soil investigations and remedial actions have been performed by RTKC in that area. Prior to a change of land use on that portion of the Site, a more rigorous records review will be performed as well as soil characterization, as appropriate. 20210351.001A/SLC22R147484_R1 Page 6 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 2.3 REGULATORY BACKGROUND The Utah Department of Environmental Quality (UDEQ) Division of Environmental Response and Remediation (DERR) and the U.S. Environmental Protection Agency (EPA) Region 8 (the Agencies) have regulatory authority for contaminated soil management within the Kennecott South Zone operable units, including the Butterfield Creek (OU3), Bastian Ditch (OU5), and Copper Creek (OU6). A 2015 joint Technical Memorandum prepared by the Agencies established soil action levels for the Kennecott South Zone Operable Units. The standards for the OUs within the Site boundaries (OU3, OU5, and OU6) are as follows: Land Use Soil Action Levels Operable Unit (OU) OU Name (Sub-Unit) Residential Arsenic / Lead (mg/kg) Commercial Arsenic / Lead (mg/kg) Recreational Arsenic / Lead (mg/kg) --- Salt Lake County Unrestricted Land Use 50/ 500 NE NE OU3 Butterfield Canyon Creek 100/ 1200 NE 283/2207 Herriman Residential and Agricultural (HAG) 100/ 1200 NE 300/ 10,000 Butterfield Waste Rock 100/ 1200 NE 283/2207 OU5 Bastian Ditch Daybreak Area 100/ 700 450/ 2000* 283/2207 Bastian Ditch (South Zone) NE NE 283/2207 OU6 Lark Waste Rock & Tailings (Includes Copper Creek) NE NE 283/2207 * Commercial Standards were established for all OUs within the Daybreak Development. The same Commercial Standards were established for all Daybreak OUs, including the OU1 Bingham Creek, OU5 Bastian Ditch, OU7 South Jordan Evaporation Pond, and OU17 Bastian Sink. The Unrestricted Land Use Standards are established by the Salt Lake County Contaminated Soils Ordinance, Title 9 Chapter 9.5. When the Kennecott South Zone OU land use standards were established, the land use in the vicinity was undeveloped or agricultural, therefore no residential or commercial land use standards were developed at that time. The 2015 Technical Memorandum is included in Appendix A. 2.4 CONTAMINANTS OF CONCERN The contaminants of concern (COCs) are lead and arsenic in soil, where the various historical waterways may have been impacted with metals-contaminated water. None of the waterway channels assessed during this investigation contained water and no water samples were collected or analyzed. 20210351.001A/SLC22R147484_R1 Page 7 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 3 INVESTIGATION ACTIVITIES ___________________________________________________________________________________ In accordance with Salt Lake County Contaminated Soils Ordinance, Title 9 Chapter 9.5, because the Site is associated with Kennecott South Zone operable units, a Site characterization was conducted to assess for the presence of elevated concentrations of lead and arsenic in Site soils. The field investigation was conducted from April through July of 2020. Prior to commencing field work, Blue Stakes of Utah Utility Notification Center (Blue Stakes) was notified to assess the potential presence and location of buried utilities. The sampling protocol discussed below was used to investigate the potential presence of elevated concentrations of lead and arsenic at the Site. The investigation activities including equipment decontamination, trenching, soil screening, soil sample collection and handling, chain of custody control and documentation were performed in accordance with the project standard operating procedures (SOPs) as presented in Appendix B. Trench photographs and exploration logs are included in Appendix C. 3.1 CREEKS AND DITCH TRENCH EXPLORATION METHODOLOGY The approximate locations of the former Bastian Ditch, Butterfield Ditch, and eastern Copper Creek alignments were identified in the field using GPS coordinates obtained from historical aerial imagery. The locations of the western Copper Creek channel and eastern Butterfield Creek channels were visible on site as incised drainages. A backhoe was used to excavate trenches perpendicular to the drainage locations. The purpose of the trenching was to identify the location, depth and width of the creek or ditch sediments remaining below grade at the Site and to assess the concentrations of lead and arsenic in the sediments. The explorations excavated during this investigation are as follows and are presented on Figures 5 through 7: • Bastian Ditch – Ten trenches were excavated perpendicular to the former Bastian Ditch alignment. An additional 34 shallow test pits were excavated east and west of the Bastian Ditch channel near its southern extent to assess metals impacts to adjacent shallow soils. • Copper Creek – Twelve trenches were excavated perpendicular to the Copper Creek drainage. • Butterfield Creek – Six trenches or test pits were excavated within the incised Butterfield Creek drainage located son the southeast corner of the Site. 20210351.001A/SLC22R147484_R1 Page 8 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com • Butterfield Ditch – Ten trenches were excavated perpendicular to the Butterfield Ditch alignment along its west-east trending segments and four along its north-south trending segment. Each trench was excavated to the depth and width necessary to identify the lateral and vertical extent of the ditch sediment at that location. The trench sediments were logged and field-screened from the sidewalls or from excavation spoils using a hand-held X-Ray Fluorescence (XRF) instrument. The dimensions of the channel, soil discolorations, and the apparent location of the ditch sediments within the trench were noted. Soil samples were collected by hand in trenches up to 4 feet below ground surface (bgs) if the soil type encountered was stable. Soil samples from trench depths greater than 4 feet bgs were collected from spoils placed on the surface by the track-hoe. When visual indicators such as discoloration or sediment deposition and XRF readings showed the apparent channel sediments, soil samples were collected representing an approximate six-inch layer exhibiting the highest lead and/or arsenic XRF measurements. In some instances, an additional sample was collected from the “clean” layer below the channel sediments based on visual indicators and XRF measurements. Generally, samples were not collected for laboratory analysis when no apparent channel sediments were present (i.e., Butterfield Ditch Trenches BFD-5 and BFD-6). Each soil sample was collected using either new disposable hand tools or decontaminated hand tools and homogenized in a new, zip-top plastic bag. Large debris and rocks were removed prior to homogenization of soil. Each soil sample was field screened with the XRF to evaluate lead and arsenic concentrations. 109 soil samples were submitted to Pace Analytical National Center for Testing and Innovation (Pace) for analysis of total lead and arsenic by EPA Method 6010B. The excavations were backfilled with the spoils in reverse order of removal (i.e., near-surface soils replaced last), compacted with the backhoe bucket, and graded to match the surrounding soil. The backfill was not compacted to an engineering standard. The trenches were logged and photographed and XRF readings were entered on the field log at the corresponding depth. The trench locations were surveyed with a hand-held global positioning system (GPS) unit with sub-meter horizontal accuracy. 20210351.001A/SLC22R147484_R1 Page 9 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 3.1.1 Bastian Ditch (OU5) Exploration Kleinfelder excavated ten trenches (BD-1 through BD-10) perpendicular to the Bastian Ditch alignment. The trench depths ranged from approximately three to four feet bgs. The width of channel sediments observed in the trenches ranged from approximately six to ten feet. Soil samples were selected for laboratory analysis based on XRF readings and metals staining observed in the sediments. An additional 34 shallow test pits (BD-10-2 through BD-10-35) were excavated to the east and west of trench BD-10 to evaluate shallow soils for metals impacts, likely due to surface overflow of water from the Bastian Ditch. Yellow and orange staining was observed in the ditch sediments in BD-1 through BD-9, generally from six to twelve inches bgs. 38 soil samples were selected for laboratory analysis from the Bastian Ditch. Bastian Ditch sample locations are presented on Figure 7. 3.1.2 Copper Creek (OU6) Exploration Kleinfelder excavated 12 trenches (CC-1 through CC-12) perpendicular to the Copper Creek alignment. The trench depths ranged from 1.5 to 12.5 feet bgs. The width of channel sediments observed in the trenches ranged from approximately 8 to 25 feet. A total of 29 soil samples were selected for laboratory analysis from Copper Creek. The sample locations are presented on Figures 6 and 7. 3.1.3 Butterfield Creek (OU3) Exploration Kleinfelder excavated trenches and test pits at six locations (BCE-1 through BCE-6) along the Butterfield Creek segment located in the southeastern portion of the Site. The explorations were excavated perpendicular to the present-day Butterfield Creek channel. BCE-1 was excavated as a trench oriented perpendicular to the Butterfield Creek channel. The total depth of BCE-1 was approximately 12 feet below the base of the channel floor. BCE-2 through BCE-6 were excavated as test pits to depths ranging from 2 to 13 feet bgs. A total of 16 soil samples were selected for laboratory analysis from Butterfield Creek. The sample locations are presented on Figure 7. 3.1.4 Butterfield Ditch Exploration Kleinfelder excavated 14 trenches along the former Butterfield Ditch, which is no longer visible at the ground surface. Four trenches, approximately 100 feet long, were excavated perpendicular to the north-south trending segment of the Ditch (BFD-1 through BFD-4). Within each of these trenches, three to four laterally spaced locations within the trench were screened and sampled for laboratory analysis (i.e. samples BFD-1-1, BFD-1-2, BFD-1-3 and BFD-1-4 were collected from Trench BFD-1). Four trenches 20210351.001A/SLC22R147484_R1 Page 10 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com were excavated perpendicular to the east-west trending segment of the Ditch (BFD-5, BFD-7, BFD-9, and BFD-13) that ran from the Bingham Tunnel to the N-S ditch segment. These trenches were extended over 30 feet long in an attempt to identify the historical location of the Butterfield Ditch. Six trenches (BDE-1 through BDE-6) were excavated perpendicular to east-west trending segment of the former Butterfield Ditch along the Site’s northeast fence line. The trenches were excavated approximately 180 feet long in an attempt to identify the historical location of the Ditch. A total of 26 shallow soil samples were collected from the Butterfield Ditch trenches at depths ranging from 0 to 1.5-foot bgs and submitted for laboratory analysis. The sample locations are presented on Figures 6 and 7. 3.2 SHALLOW FLOOD PLAIN EXPLORATION METHODOLOGY Kleinfelder assessed the distribution of metals impacts in shallow soils on the eastern portion of the Site that appear to be related to surface overflow of the Bastian Ditch and Butterfield Ditch North-South trending segment. The Bastian Ditch appears to have lost its channelization on the southern portion of the Site and allowed metals-impacted water to flow across the ground surface in this area. Based on the distribution of metals concentrations detected in the soil, the Butterfield Ditch also appears to have overflowed to the east of its alignment. Ninety locations (ES-1 though ES-90) were assessed using a backhoe and 173 soil samples were submitted for laboratory analysis of lead and arsenic. The shallow floodplain soil samples were collected in a grid pattern at an approximate 300-foot spacing. Soil sample depths were selected based on XRF readings. The shallow soil exploration extended north to south and east to west until the apparent extent of the shallow soil impacts were delineated. The shallow floodplain sample locations are presented on Figures 7 and 8. The test pits were excavated to a maximum depth of approximately 24 inches bgs. During the sample collection process, an XRF unit was used to measure relative lead and arsenic concentrations in the soil at six-inch intervals. In each test pit, Kleinfelder assessed the depth extent of the metals impacts by screening the near surface soil at six-inch intervals until a “clean” interval was identified below the impacted zone. In general, soil samples were collected from each interval with elevated lead or arsenic XRF readings, plus the “clean” interval below. The soil samples were given suffixes that identified the collection depth (i.e., “A” series samples were collected from the 0- to 6-inch interval, and the “B” series samples were collected from the 6- to 12-inch interval, etc.). Samples were collected according to the same procedure described in Section 3.1 and presented in the SOPs in Appendix B. A total of 155 soil samples were submitted for laboratory analysis of total lead and arsenic by EPA Method 6010B. 20210351.001A/SLC22R147484_R1 Page 11 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 3.3 BINGHAM TUNNEL EXPLORATION METHODOLOGY Kleinfelder assessed the location and condition of the Bingham Tunnel Pipeline system (see Figure 6). The Bingham Tunnel Pipeline consists of two transite pipes (eight-inch and ten-inch diameter) that were used to transport mine tailings water from Kennecott operations to the north, across the west-central portion of the Site to Butterfield Creek for use as irrigation water in Herriman City, south of the Site. A third concrete pipe (15-inch diameter) runs from the Bingham Tunnel outfall concrete vault to the former Dansie Pond. Kleinfelder’s assessment consisted of three components: an inspection of the pipeline to verify its integrity and physical location, soil sampling at the pipeline diversion box near Dansie Pond, and sampling of the scale found on the inside of the pipes. To verify the integrity and physical location of the Bingham Tunnel, Kleinfelder directed a backhoe operator to dig a shallow test pit perpendicular to the pipeline’s suspected location. Once the pipes were located, soil was carefully removed so that the pipes could be inspected. A total of 17 test pits were excavated to identify the location of the pipeline. In eight locations (see Figure 6), Kleinfelder directed the backhoe operator to carefully break the transite piping open to assess whether metals-impacted sediment had deposited in the piping. Four soil samples (WD-1, WD-1B, WD-2, and ED-1) were collected adjacent to the concrete diversion box where water was diverted via piping to the Dansie Pond. The soil samples were screened and collected using the same procedures and laboratory analysis as described in Section 3.1. To assess the pipe interior for metals impacts, Kleinfelder collected four samples of the hard scale that lined the interior of the two pipes by scraping the piping sidewall. The scale was only observed in pipes in the far northern portion of the Site. Sidewall scale samples were collected from both transite pipes at two test pit locations (BT1 and BT2). The samples were labeled using the following nomenclature: Bingham Tunnel Test Pit 1 Pipe 1 (8-inch pipe) labeled BT1-1, and Test Pit 1 Pipe 2 (ten-inch pipe) labeled BT1-2. A clean stainless-steel scraping tool was used to remove the scale from the inside of the pipe at each sample location. The scale was placed into clean, laboratory-provided sample containers, and transported under chain of custody documentation to Pace for analysis of total lead and arsenic by EPA Method 6010B. 20210351.001A/SLC22R147484_R1 Page 12 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 4 ANALYTICAL RESULTS ___________________________________________________________________________________ The analytical results obtained from the Site investigation are presented in the following sections. The analytical results were compared to soil action levels established for Kennecott South Zone Operable Units OU3, OU5, and OU6 and the Salt Lake County Contaminated Soils Ordinance: • Recreational Land Use Standards - 2,207 mg/kg lead and 283 mg/kg arsenic. • Unrestricted Land Use Standards - 500 mg/kg lead and 50 mg/kg arsenic. The Site is proposed for development as mixed-use residential, commercial, and recreational property. When the land use standards were established for these operable units, the area was open space and agricultural land, therefore no Residential or Commercial Land Use Standards were established. As detailed herein, metals concentrations were identified in Site soils that exceed the Unrestricted Land Use Standards, and in some locations the Recreational Land Use Standards for lead and arsenic. The laboratory analytical results are summarized in Tables 1 through 4. The quality assurance laboratory results are presented in Table 5. Copies of the laboratory analytical reports and chain of custody documentation are included in Appendix D. 4.1 CREEK AND DITCH INVESTIGATION RESULTS The results for the investigations of the Bastian Ditch, Copper Creek, Butterfield Creek, and the Butterfield Ditch are presented below. The sample locations and color-coded analytical results are presented on Figures 5, 6 and 7. The analytical results are presented on Tables 1, 2 and 3. 4.1.1 Bastian Ditch (OU5) Investigation Results Kleinfelder excavated ten trenches (BD-1 through BD-10) up to 20 feet long across the Bastian Ditch alignment (see Figures 5 and 7). The buried ditch channel was observed to be approximately six to ten feet wide. The impacted soils were visually evident with yellow, red, and green staining and were generally limited to the upper three feet of soil, with the exception of trench BD-8, where soils were impacted to a depth of four feet bgs. 20210351.001A/SLC22R147484_R1 Page 13 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com Soil containing lead and arsenic at concentrations exceeding the Unrestricted Land Use Standards were detected in all ten trenches with the highest concentrations detected within the upper one foot. The maximum lead and arsenic concentrations reported in the Bastian Ditch soil samples were 38,000 mg/kg lead and 1,040 mg/kg arsenic (in BD-8). Four of the ten trenches sampled (BD-5, BD-7, BD-8, and BD-9) contained metals concentrations above the Recreational Land Use Standards. The analytical results are presented in Table 1. 4.1.2 Copper Creek (OU6) Investigation Results Kleinfelder excavated twelve trenches (CC-1 through CC-12) up to 40 feet long across the Copper Creek alignment (see Figures 5, 6 and 7). The channel width was observed to range from approximately 8 to 25 feet. Soil staining was not visible in most of the trenches. When metals impacts were present, a fine layer of red staining was observed directly above a white sediment layer. The metals-impacted soils were generally limited to the upper 4.5 feet of soil, with the exception of trench CC-6, where soils were impacted to a depth of ten feet bgs. Due to the limited number of sample locations and the non-homogenous nature of the Creek channel deposits in this large drainage; this investigation did not fully delineate the depths of impacts along the entire Copper Creek drainage. Although complete vertical delineation was not achieved along the entire drainage, this is not considered a data gap as full delineation will be determined by confirmation sampling during future remedial actions. Vertical delineation was achieved in trenches CC-3 through CC-9 and CC-12 and not in CC-1, CC-2, CC-10, and CC-11. Soil containing lead and arsenic at concentrations exceeding the Unrestricted Land Use Standards were identified in six of the trenches (CC-1, CC-2, CC-3, CC-6, CC-10, and CC-11). The maximum lead and arsenic concentrations reported in the Copper Creek soil samples were 16,500 mg/kg lead and 461 mg/kg arsenic (in trench CC-10). The metals concentrations detected were lower than those in the Bastian Ditch, with just one of the twelve trenches (CC-10) containing metals concentrations above the Recreational Land Use Standards. The analytical results are presented in Table 1. 4.1.3 Butterfield Creek (OU3) Investigation Results Kleinfelder excavated six trenches (BCE-1 through BCE-6) up to 20 feet long across the segment of the Butterfield Creek drainage located in the far southeast corner of the Site (see Figures 5 and 7). This area is intended to remain as open space and the analytical results were compared to the Recreational Land Use Standards. The Creek channel is visible on the ground surface and is approximately 15 feet below the surrounding grade and 50 feet wide on its west side, tapering to three feet deep and ten feet wide 20210351.001A/SLC22R147484_R1 Page 14 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com on the east end. Occasional yellow soil staining was observed in some trenches. The metals-impacted soils were observed from ground surface (on the bottom of the Creek) to 14 feet deep (the extent of the backhoe reach). The maximum lead and arsenic concentrations reported in the near surface soils (zero to one foot bgs) were 5,100 mg/kg lead and 95.7 mg/kg arsenic, which are below the Recreational Land Use Standards. The maximum lead and arsenic concentrations detected in the deeper (1 to 14-foot bgs) soils were 21,300 mg/kg lead and 251 mg/kg arsenic. As the data shows, lead and arsenic concentrations in the Butterfield Creek channel are generally higher below the surficial deposits. Soil samples collected from three test pit locations (BCE-1, BCE-3 and BCE-5) exceeded the Recreational Land Use Standards. The analytical results are presented in Table 1. 4.1.4 Butterfield Ditch Investigation Results Kleinfelder excavated 14 trenches along the former Butterfield Ditch, which is no longer visible at the ground surface. The trench locations are indicated on Figures 5, 6 and 7. No soil discoloration or channelization of sediments were observed in any of the Butterfield Ditch trenches that would indicate the presence of a buried Ditch alignment. Elevated XRF readings were identified only in the north-south trending Ditch segment. The investigation results are presented below by segment location. The analytical results are presented in Table 2. North-South Trending Segment Four trenches (BFD-1 through BFD-4) were excavated along the former Butterfield Ditch north-south trending segment. Soils containing lead and arsenic at concentrations exceeding the Unrestricted Land Use Standards were identified in trenches BFD-1, BFD-2, BFD-3, and BFD-4 in shallow soils up to one-foot bgs. The maximum lead and arsenic concentrations reported in the north-south trending segment of the Butterfield Ditch soil samples were 1,290 mg/kg lead and 53.5 mg/kg arsenic (both from BFD-2), which are below the Recreational Land Use Standards and above the Unrestricted Land Use Standards. Vertical delineation to the Unrestricted Standard was not achieved in trenches BFD-2, BFD-3, and BFD-4. 20210351.001A/SLC22R147484_R1 Page 15 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com Western West-East Trending Segment Four trenches (BFD-5, BFD-7, BFD-9, and BFD-13) were excavated along the east-west trending segment of the Butterfield Ditch that runs across the center of the Site. No soil discoloration or channelization of sediments were observed that would indicate the presence of a buried Ditch alignment and no metals concentrations were detected via XRF screening or laboratory analysis that identified metals-impacted soil above the Unrestricted Land Use Standards. The maximum lead and arsenic concentrations reported were 185 mg/kg lead and 18.9 mg/kg arsenic (both from BFD-9), which are below the Unrestricted Land Use Standards. Northeastern West-East Trending Segment Six trenches (BDE-1 through BDE-6) were excavated perpendicular to east-west trending segment of the former Butterfield Ditch along the Site’s northeast fence line. No soil discoloration or channelization of sediments were observed that would indicate the presence of a buried Ditch alignment and no metals concentrations were detected via XRF screening or laboratory analysis that identified metals-impacted soil above the Unrestricted Land Use Standards. The maximum lead and arsenic concentrations reported were 297 mg/kg and 27.3 mg/kg, respectively, which do not exceed the Salt Lake County Unrestricted Land Use Standards. 4.2 SHALLOW FLOOD PLAIN INVESTIGATION RESULTS Kleinfelder collected 173 shallow soil samples from 90 test pits extending from adjacent to the Bastian Ditch to east of the Butterfield Ditch north-south trending segment (see Figures 5, 7 and 8). Soil samples were selected for laboratory analysis based on the XRF readings. The shallow soil exploration extended north to south and east to west until the apparent extent of the shallow soil impacts were delineated. Twenty of the 90 test pit locations contained lead concentrations in soil above the Unrestricted Land Use Standard, and one test pit contained arsenic above that standard. Where detected, the metals impacts were generally restricted to the upper 6 inches of soil, with impacts extending to one foot bgs in some locations, as indicated on Figure 8. None of the samples analyzed contained lead or arsenic concentrations above the Recreational Land Use Standards. The maximum reported lead and arsenic concentrations in the samples collected during the shallow flood plain exploration were 1,350 mg/kg lead (in ES-34A), and 52.2 mg/kg arsenic (in ES-63A). Sample ES-63A was the only soil sample in which arsenic concentrations were reported above the Unrestricted 20210351.001A/SLC22R147484_R1 Page 16 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com Land Use Standard of 50 mg/kg. Of the 90 test pit locations, vertical delineation to the Unrestricted Land Use Standards was not achieved at four locations (ES-46, ES-55, ES-70, and ES-77). Although complete vertical delineation was not achieved at these locations, this is not considered a data gap as full delineation will be determined by confirmation sampling during future remedial actions. Vertical delineation was achieved at the remaining 86 locations, with soil containing lead and arsenic at concentrations above the Unrestricted Land Use Standards generally restricted to the upper 12 inches. The analytical results are presented in Table 3. 4.3 BINGHAM TUNNEL INVESTIGATION RESULTS Kleinfelder’s assessment included inspecting the transite pipeline to verify its integrity and physical location, soil sampling at the pipeline diversion box near Dansie Pond, and sampling of the sediment or scale found inside the pipes. A total of 17 test pits were excavated to identify the location of the pipelines and the piping interior was inspected at eight locations. In all locations, the two adjacent pipes were intact and no indication of water leakage or metals-impacts to adjacent soils were observed. 4.3.1 Piping Assessment In eight locations (see Figure 6), Kleinfelder directed the backhoe operator to carefully break open the transite piping to assess whether metals-impacted sediment had deposited in the piping. At the seven locations along the main Bingham Tunnel pipeline, no sediment buildup was observed in the pipes. In the Dansie Pond diversion pipe, approximately one inch of sediment was observed and sampled (ED-1). In five locations where the piping was opened both pipes were dry; while in three locations shallow standing water was observed in both pipes (as detailed in Table 4). In two test pit locations(BT1 and BT2) hard scale was observed on the inside of both transite pipelines. Samples of the scale were collected from both transite pipes in two locations (BT1-1, BT1-2, BT2-1 and BT2-2) by scraping the scale material into a sample container. The maximum reported lead and arsenic concentrations in the scale samples were 813 mg/kg lead in sample BT2-2 and 802 mg/kg arsenic in sample BT1-2. 4.3.2 Bingham Tunnel Outfall Soil Assessment Kleinfelder assessed soils at the Bingham Tunnel outfall concrete diversion box near the south end of the Tunnel and the Dansie Pond. Two trenches were excavated on the west side of the diversion box and one trench was excavated on the east side (WD-1, WD-2, and ED-1); labeled using WD prefix for “west ditch” and ED prefix for “east ditch). Seven soil samples were collected from the three trenches and submitted for laboratory analysis. The maximum lead and arsenic concentrations detected in the 20210351.001A/SLC22R147484_R1 Page 17 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com soil were 1,070 mg/kg lead and 986 mg/kg arsenic in WD-1 at two feet bgs. Lead concentrations exceeded the Unrestricted Land Use Standard in all three test pits. Arsenic concentrations exceeded the Unrestricted Land Use Standard in two of the test pits (ED-1, WD-1) with arsenic exceeding the Recreational Land Use Standard in test pit WD-1. The analytical results are presented in Table 4. The Bingham Tunnel Outfall test pits were intended to assess the potential for soil impacts near the outfall culvert via limited sampling in the area. The lateral and vertical extent of soil impacts was not delineated during this assessment. Although complete soil impacts delineation was not achieved at this location, this is not considered a data gap as full delineation will be determined by confirmation sampling during future remedial actions. 20210351.001A/SLC22R147484_R1 Page 18 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 5 DATA QUALITY OBJECTIVES AND QA/QC ___________________________________________________________________________________ 5.1 FIELD QUALITY ASSURANCE/QUALITY CONTROL Quality Assurance (QA) and quality control (QC) procedures associated with the subsurface investigation were implemented to produce data that are accurate, credible, and representative of conditions at the Site. Kleinfelder’s QA/QC procedures for this project included: • Careful record keeping and documentation; • Use of appropriate equipment and decontamination procedures; • Split Quality Assurance samples; • Documentation of Chain-of-Custody; and • The samples were submitted to PACE, a state certified laboratory, which follows QA/QC procedures consistent with USEPA standards. Laboratory QA/QC samples included method blanks, matrix spikes, duplicates and calibration check samples. QA statements for the lab samples are included with the laboratory reports in Appendix D. Quality control for the sampling program included using standardized sample collection and handling methods, documenting pertinent field information, and keeping chain-of-custody records as prescribed herein. Single-use, disposable sampling tools were used for sample collection, or non-disposable sampling equipment was decontaminated between each sample location. 5.2 DATA QUALITY ASSESSMENT REVIEW The purpose of data quality assessment is to provide assurance that data generated under the QA/QC program is reconciled, accurate and consistent with program data quality objectives (DQOs). The quality of the data was assessed based on precision, accuracy, completeness, representativeness, and comparability. The collected samples were analyzed for total arsenic and lead, petroleum hydrocarbon constituents and volatile organic compounds. The samples were analyzed at Pace National Analytical Laboratory (Pace). 20210351.001A/SLC22R147484_R1 Page 19 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com A review of the laboratory analytical reports indicated all sample analyses were performed within holding times, the samples were analyzed following the correct methods, all instruments and calibration check requirements were met, and the method blanks did not report concentrations of either lead or arsenic. Precision is the degree to which a measurement is reproducible and is quantitatively measured by calculating the Relative Percent Difference (RPD) of two measurements. Precision in terms of the RPD was evaluated on an intra-laboratory basis. RPD is defined as: RPD= [(A1-A2)/((A1+A2)/2)]*100 Where A1 = Analytical result from sample #1 A2 = Analytical result from sample #2 Intra-laboratory precision was assessed by calculating the RPD between the original sample and its’ field duplicate. One out of every ten samples collected for lab analysis was split two ways for a total of 29 duplicate samples. The samples were split with one portion submitted as a standard analytical sample and one portion as a blind duplicate. The data quality objective for the split sample analyses is an RPD of <35%. The RPD of the split duplicate samples met the goal of less than 35% for 53 of the 58 analyses (91 percent), as presented in Table 3. The RPD goal exceedance of the three soil samples is likely due to the non-homogenous nature of the sampled soils. Representativeness was assessed by verifying the samples were analyzed within their analytical method holding times and that method blanks do not report any contamination. A review of the laboratory analytical reports indicated all sample analyses were performed within holding times and the method blanks did not report concentrations of either lead or arsenic above the laboratory reporting limit. Comparability was assessed by the units of measure reported in the analytical results compared to the units of measure established for the action levels and by using analytical methods that are comparable to other similar studies in the same area and under the same regulatory framework. The units of measure reported by the laboratory are the same units of measure for the action levels and the analytical methods employed are consistent with similar studies conducted in the area. Percent Completeness was measured as the number of samples that were within the established control limits for all quality control parameters. With 324 soil and sediment samples collected, each analyzed for total lead and arsenic, there are 648 total analytical results. Of the 648 analytical results, 14 individual analytical results were qualified, which represents 2.16% of the sample analyses performed. As such, 20210351.001A/SLC22R147484_R1 Page 20 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 97.84% of the sample results were not qualified and are considered valid, which exceeds the DQO of 90% valid data. Based on our review of the analytical data and associated data quality assessment findings, we believe that the data may be used for the intended purpose of characterizing the Site soils. 5.3 QUALITY ASSURANCE/QUALITY CONTROL Quality control for the sampling program included using standardized sample collection and handling methods, documenting pertinent field information, and keeping chain-of-custody records as prescribed herein. Single-use, disposable sampling tools were used for sample collection, or non-disposable sampling equipment was decontaminated between each sample location. 20210351.001A/SLC22R147484_R1 Page 21 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 6 SUMMARY OF PRIOR SITE INVESTIGATIONS ___________________________________________________________________________________ Several environmental investigations and one remedial action have been completed on portions of the Site over the last 25 years, all related to potential metals impacts to soil from historical mining operations in the Oquirrh Mountains. Excerpts from these reports along with associated tables and figures are included in Appendix A. The following provides a chronological summary of those historical Site activities. 6.1 1996/1997 BUTTERFIELD CREEK/HERRIMAN SOIL INVESTIGATION Portions of the Olympia Hills property were investigated by Rio Tinto Kennecott Utah Copper in 1996/1997. Their Butterfield Creek/Herriman Soil Investigation report documents the historic transport of lead and arsenic contaminated water via creeks, ditches, and tunnels that were utilized by the town of Herriman for irrigation purposes. Sources of contamination were derived from historic mining and milling operations that occurred from the 1870s to the 1950s in the mountain range west of the Site. Historically contaminated creeks and irrigation systems described in the RTKC Soil Investigation Report included the Bastian Ditch, the Bingham Tunnel, the Butterfield Ditch, Copper Creek and Butterfield Creek. The investigation included sampling and laboratory analysis of 119 soil samples collected from 23 soil borings on the Olympia Hills property. Five of these soil borings were advanced in the vicinity of the Butterfield Creek/Bastian Pasture to a depth of 19 feet bgs. Fourteen borings were advanced in the vicinity of the Bastian Ditch and Butterfield Ditch. Four borings were advanced across the center of Olympia Hills in an area referred to by RTKC as “western agricultural land”. Of the 119 total soil samples collected, only one sample (location BH-DH-31 collected from 0-0.7 ft and 0.7-1.7 ft bgs), exhibited metals concentrations exceeding the Unrestricted Land Use Standards of 50 mg/kg arsenic and 500 mk/kg lead. The sample was collected at the intersection of the Bastian Ditch and Butterfield Ditch on the Sites southern property line. Figures and data tables excerpted from the RTKC report are presented in Appendix A. Additional details regarding this investigation can be found in Kennecott Utah Copper’s Report Butterfield Creek/Herriman Soil Investigation Report, October 1996 – February 1997. 20210351.001A/SLC22R147484_R1 Page 22 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 6.2 2000 HERRIMAN DEVELOPABLE LANDS SOIL INVESTIGATION Near surface soils in the far southeast portion of the Site were characterized by the UDERR in 1999 as part of the Herriman Developable Lands investigation. Approximately 10,450 surface soil samples were collected from Herriman developable lands between August and December of 1999 within OU3 Herriman Residential and Agricultural land. The far southeast portion of the Site lies within the investigation area identified as Herriman Agricultural Grounds-008 (HAG-008). The Site soils with OU3 Butterfield Creek (further to the west) were not sampled during the HAG assessment due to denial of access to the property by a former owner. At each sample location, composite soil samples were collected from the surface, 0 to 6 inches, 6 to 12 inches, and 12 to 18 inches deep. There were approximately 81 sample locations within the Olympia Hills property (north of Butterfield Creek). The samples were analyzed for lead and arsenic using an x-ray fluorescence meter (XRF) with one sample for every 30 collected sent to a laboratory for analysis. The majority of the detected concentrations were below the OU3 Herriman Residential Land Use Standards for lead and arsenic of 1,200 mg/kg and 100 mg/kg, respectively. One small area near Butterfield Creek (sample B-7 at a depth between 0.5 and 1.5 feet bgs), had concentrations exceeding the OU3 Herriman Residential Land Use Standards. The HAG-008 lead and arsenic maps and data tables are presented in Appendix A. Additional details regarding this investigation can be found in Utah DERR’s Report Analytical Results Report, Herriman Developable Lands, June 2000. 6.3 BUTTERFIELD CREEK FLOOD SEDIMENT SOIL MITIGATION Shallow metals-impacted soils associated with a 2013 Butterfield Creek flooding event were remediated by RTKC within Butterfield Canyon and on the Last Holdout property (Bastian Farm) in 2014. The 2014 Butterfield Creek Sediment Post-Removal Report and Last Holdout LLC Soil Mitigation Summary documented cleanup efforts along the Butterfield Creek where it traverses the southwest portion of the Site. According to the reports, storm related sediments containing elevated concentrations of lead and arsenic were deposited along areas of the Butterfield Creek during a flood event on September 13 and 14, 2013. A total of 8.74 acres, that included portions of the Site and surrounding properties, were impacted as a result of the storm event. The report indicates the sediment was several inches thick and the impacted areas were easily identified given that the storm sediment was yellow/brown silt and clay. The impacted soil were remediated through excavation and off-site disposal and deep tilling (within the 20210351.001A/SLC22R147484_R1 Page 23 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com Bastian farmed field) to the OU3 Butterfield/Herriman Residential Standards, with the exception of the following. Two soil confirmation samples (BTCX-40 and BTCX-41) collected at three to five inches bgs, located on Site just north of Herriman Highway, contained conentrations of metals in soil above the OU3 Residential Land Use Standards for lead and arsenic (up to 3170 mg/kg lead and 154 mg/kg arsenic). The samples did not exceed the OU3 Agricultural Standards which applied due to the location of the samples in the Bastian farm field. The impacted soil extended under Herriman Highway and was not removed due to concerns of jeopardizing road stability. The Last Holdout LLC Soil Mitigation Summary, which summarizes the cleanup activites on the Site, is included in Appendix A. Additional details regarding the Butterfield Creek flood sediment remedial actions can be found in RTKC’s reports Butterfield Creek Sediment Post-Removal Report, October 2014; and The Lase Holdout LLC Soil Mitigation Summary, July 2014. 6.4 PHASE I ENVIRONMENTAL SITE ASSESSMENT AND SOIL SCREENING A Phase I ESA was conducted by Wasatch Environmental Inc. of the approximate 900-acre Olympia Hills property in 2017. The Site was reported to have consisted of land under agricultural production with farming related structures. The Site historically had several underground storage tanks (USTs) including one 6,000- gallon gasoline UST, one 8,000-gallon diesel UST, and one 500-gallon gasoline UST. The tanks were removed in 1997. Approximately 43 cubic yards of contaminated soil were removed at that time. Petroleum hydrocarbon concentrations in the confirmation samples were below Utah Initial Screening Levels (ISLs). The release received regulatory closure on June 19, 1997. Given the history of heavy metal impacts in the vicinity of the Site, Wasatch Environmental screened surface soils with an XRF at 53 locations. Areas of investigation included Copper Creek, Butterfield Creek, the Bastian Ditch, the areas that were remediated after the 2013 flood event, and the northern property boundary. Surface soil samples SS-1 through SS-5 were collected on October 18, 2017, in areas where elevated lead and arsenic concentrations were detected by the XRF. All five laboratory-analyzed samples detected lead and arsenic concentrations below the OU3 Herriman Soils Residential Land Use Standards. Sample SS-5 was located outside of OU3; therefore, the Salt Lake County Unrestricted Land Use Standards would apply for a residential land use in that area. The analytical results for lead exceeded that standard, at 819 mg/kg. It appears SS-5 was located near the Bastian Ditch alignment which was further assessed during Kleinfelder’s soil investigation. A table summarizing the XRF measurements and laboratory analytical results are presented in Appendix A. 20210351.001A/SLC22R147484_R1 Page 24 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com The Phase I ESA report identified the following Recognized Environmental Conditions (RECs): • Groundwater beneath the subject property is impacted with sulfate from historical mining operations which occurred in the Oquirrh Mountains to the west; however, given the depth to impacted groundwater and assuming drinking water will be provided by the local municipality, exposure to the groundwater plume would not be likely. • Moderate oil staining in the vicinity of the used oil drums east of the main storage structure, and moderate oil staining south of the main storage structure; • There is a likely presence of elevated lead and arsenic in soil at depths between three and four feet bgs along the Butterfield Ditch and Bastian Ditch. Soil contamination, if present within these former ditches, would be encountered at a depth of 3 to 4 feet. • There is a potential for impacts to the subject property from future Butterfield Creek flood events. Additional details regarding the Phase I ESA can be found in Wasatch Environmental’s report Phase I Environmental Site Assessment, 900-Acre Herriman Aquisitiont, Southwest Corner of Salt Lake County, Herriman, Utah 84096, November 13, 2017. 20210351.001A/SLC22R147484_R1 Page 25 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 7 KLEINFELDER’S PHASE II INVESTIGATION FINDINGS ___________________________________________________________________________________ The Site contains historical waterways (natural and man-made) that are known to have carried metals- impacted water and sediment. The Site contains segments of three Kennecott South Zone Operable Units, OU3 Butterfield Creek/Herriman Agricultural and Residential, OU5 Bastian Ditch and OU6 Copper Creek, as well as two non-OU waterways, the Butterfield Ditch and the Bingham Tunnel transite pipeline. Kleinfelder conducted this Site characterization to assess for the presence of elevated metals associated with the various drainages. This investigation identified metals concentrations in Site soils that exceeded the Unrestricted Land Use Standards, and in some locations the Recreational Land Use Standards for lead and arsenic. A summary of the findings of this investigation, by waterway feature, is provided below. • Bastian Ditch (OU5) – Metals impacts to soils in the Bastian Ditch drainage were reported at concentrations exceeding the Unrestricted Land Use Standards in all trenches excavated, generally within the upper 18 inches of soil. Four of the ten trenches sampled contained metals concentrations above the Recreational Land Use Standards. The location of the historical waterway and approximate lateral extent of metals-impacted soils were identified. • Copper Creek (OU6) – Metals impacts to soils in Copper Creek were reported at concentrations exceeding the Unrestricted Land Use Standards at depths up to 9.5 feet below the ground surface. One of the twelve trenches sampled contained metals concentrations above the Recreational Land Use Standards. The location of the historical waterway and approximate lateral extent of metals-impacted soils were identified. • Butterfield Creek (OU3) – Metals impacts to soils in the Butterfield Creek drainage, located in the southeastern portion of the Site, were reported at concentrations exceeding the Unrestricted Land Use Standards at depths up to 14 feet bgs. Full vertical delineation of lead and arsenic impacted soil was not achieved due to the depth at which contamination was encountered. Three of the six trenches sampled contained metals concentrations above the Recreational Land Use Standards. • Butterfield Ditch – Metals impacts to soils were detected along the north-south trending segment of the Butterfield Ditch alignment at concentrations exceeding the Unrestricted Land Use Standards, generally confined to the upper 12-inches of soil. None of the samples analyzed 20210351.001A/SLC22R147484_R1 Page 26 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com exceeded the Recreational Land Use Standards. No metals concentrations were detected above the Unrestricted Land Use Standards in the west-east trending segments of the Butterfield Ditch. • Shallow Flood Plain Soils– Metals impacts to the shallow flood plain soils were reported at concentrations exceeding the Unrestricted Land Use Standards in 20 of the 90 test pit locations sampled, generally within the upper 12 inches of soil. None of the samples analyzed exceeded the Recreational Land Use Standards. • Bingham Tunnel Transite Pipeline –Lead impacts to soil at the south outfall of the tunnel were reported at concentrations exceeding the Unrestricted Land Use Standards, generally within the upper two feet of soil. Arsenic in soil was detected above the Recreational Land Use Standard in two of the four test pits. Elevated metals concentrations were reported in samples of the hard scale found inside the tunnel piping. Because Site development is planned for mixed-use residential, commercial, and open space, a Soil Management Plan (SMP) must be developed to direct the mitigation of the metals-impacted soils in compliance with the proposed land uses. When the Kennecott South Zone Land Use Standards were established by the Agencies, the area was open space and agricultural land, therefore no Residential or Commercial Land Use Standards were established. The Salt Lake County Unrestricted Land Use Standard is appropriate for a residential setting. Commercial Land Use Standards should be established for the Site to allow for appropriate and financially feasible remediation of commercially plotted areas. 20210351.001A/SLC22R147484_R1 Page 27 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 8 LIMITATIONS ___________________________________________________________________________________ This work was performed in a manner consistent with that level of care and skill ordinarily exercised by other members of Kleinfelder’s profession practicing in the same locality, under similar conditions and at the date the services are provided. Our conclusions, opinions and recommendations are based on a limited number of observations and data. It is possible that conditions could vary between or beyond the data evaluated. Kleinfelder makes no other representation, guarantee or warranty, express or implied, regarding the services, communication (oral or written), report, opinion, or instrument of service provided. Kleinfelder offers various levels of investigative and engineering services to suit the varying needs of different clients. It should be recognized that definition and evaluation of geologic and environmental conditions are a difficult and inexact science. Judgments leading to conclusions and recommendations are generally made with incomplete knowledge of the subsurface conditions present due to the limitations of data from field studies. Although risk can never be eliminated, more detailed and extensive studies yield more information, which may help understand and manage the level of risk. Since detailed study and analysis involves greater expense, our clients participate in determining levels of service that provide adequate information for their purposes at acceptable levels of risk. More extensive studies, including subsurface studies or field tests, should be performed to reduce uncertainties. This report may be used only by the client and only for the purposes stated within a reasonable time from its issuance. Land use, Site conditions (both on- and off-Site), or other factors may change over time, and additional work may be required. Non-compliance with any of these requirements by the client or anyone else, unless specifically agreed to in advance by Kleinfelder in writing will release Kleinfelder from any liability resulting from the use of this report by any unauthorized party. 20210351.001A/SLC22R147484_R1 Page 28 of 28 December 6, 2022 © 2023 Kleinfelder Revision No. 1 date March 15, 2023 www.kleinfelder.com 9 REFERENCES ___________________________________________________________________________________ EPA, 2015.

Primarily an agricultural community, the town of Herriman was settled in the 1850s and has utilized water from upstream sources for irrigation since that time. Sources of contamination appear to be from historic mining and milling operations from the 1870s to the 1950s in Butterfield Canyon and the eastern slopes of the Oquirrh Mountains south of Bingham Creek. Beginning in 1962, Kennecott Utah Copper Corporation (KUC) acquired ownership of these historic mining and milling properties. The EPA has determined that the residential soil contamination and any continuing sources of this contamination will require mitigation. A soil characteristic investigation has been conducted to identify possible sources of contamination and migration pathways for contaminant dispersal upstream of Herriman and to assess the distribution of lead and arsenic in soil and sediment in the vicinity of Herriman. 2.0 This report describes the Butterfield Creek/Herriman Site (Site), mining history, sample locations, sampling procedures, and presents the results of this investigation. The site characterization activities were designed to yield data sufficient to support decision making for assessment and/or mitigative activities for the Site. Additional phases of investigation may be conducted to further characterize the Site and the nature and extent of contamination, and to aid in the evaluation of potential clean-up options. KUC will submit findings of this investigation to the EPA and DERR. SITE LOCATION AND DESCRIPTION The area of investigation is located approximately 15 miles southwest of Salt Lake City, in Salt Lake County, Utah, west and northwest of the community of Herriman in southwest Jordan Valley (Map 451-T-4620). Butterfield Canyon is located on the eastern slope of the Oquirrh Mountains approximately 3.75 miles south of Bingham Canyon. Several tributaries join the - 4 mile long Canyon which ranges in elevation from 7000 feet to 5440 feet. Bedrock in Butterfield Canyon consists primarily of Pennsylvanian quartzite and limestone of the Butterfield Formation which were intruded by Tertiary latite sills and dikes. Penetration of metal laden fluids from the volcanic intrusives into faults/fractures of the host rock produced ore mineralization. The ore mineralization commonly occurs at KUC/EEPG BHSIR.DOC 8/4/97 3.0 the limestone/volcanic contact as veins of silver-lead sulfides and carbonates, with accessory gold, iron, zinc, and copper (1). The bedrock is overlain by Quaternary alluvial and colluvial deposits derived from the local bedrock. The alluvial and colluvial deposits consist of clayey to sandy gravel. These deposits merge and inter-finger with Quaternary lacustrine and deltaic valley-fill sediments along the base of the Oquirrh Mountains. The surface of the Quaternary alluvium has been shaped by inundation of historic Lake Bonneville. Several varieties of soil have been identified in Butterfield Canyon. The soil is predominately clayey silty gravel with minor clay and clayey silt to clayey sandy gravel and silty gravel. Soil in the agricultural area around Herriman consists mainly of gravely loam, with abundant cobbles in areas of historic drainage bottoms. Butterfield Creek drains Butterfield Canyon of runoff from melting snow, small springs, groundwater inflow, as well as water from Butterfield tunnel. Approximately one half of the water in the creek comes from Butterfield tunnel. Runoff from the upper gulches is now captured by cutoff walls constructed by KUC and used in its operations. Butterfield Creek is diverted to the Herriman ditch at the mouth of the canyon to irrigate fields west and northwest of Herriman. There is currently no flow in the Butterfield Creek channel in the vicinity of Herriman. The original channel has been graded, plowed and is in agricultural use. Historically, water from several other locations, including Bingham and Mascotte tunnels, has been periodically diverted for irrigation use near Herriman. Land use in the vicinity of Herriman is primarily agricultural. Butterfield Canyon is utilized primarily for recreation and the northern limits of the canyon are part of the KUC Bingham Pit waste rock dumps. SITE HISTORY The town of Herriman was settled around 1852 as an agricultural community utilizing Butterfield Creek for both culinary and irrigation purposes. Mining activities began in upper Bingham Canyon, expanding by the 1870s to the east side of the Oquirrh Mountains and to Yosemite, Saints Rest, Black Jack, and St. James gulches that drain into Butterfield Creek. In 1875 or 1876 the Revere Mill was constructed in Butterfield Canyon at the mouth of Saints Rest Gulch, about three miles west of Herriman. Tailings from lead ores processed at the mill were probably washed into Butterfield Creek. The mill was renamed Yosemite Mill after being purchased by the Yosemite Mining Company possibly in the late 1880s. The mill was destroyed by fire around 1900 and was never rebuilt. Around 1892 to 1894, the Butterfield tunnel was constructed approximately 2 ½ miles upstream from Highway 111, and waste rock from the tunnel and related workings was deposited within and adjacent to Butterfield Creek. Butterfield Mining Company, owners KUC/EEPG BHSIR.DOC 8/4/97 of the tunnel, claimed all water rights of water from the tunnel and erected a diversion near the mouth of the canyon to convey the water for irrigation of their property located approximately one mile northwest of Herriman. Mining operations occurred through the Butterfield tunnel into the 1950s. The waste rock from the Butterfield tunnel was removed by KUC in 1993 under an Administrative Order of Consent with the EPA. The Butterfield Mining Company’s claim to the Butterfield tunnel water was challenged by the Herriman Irrigation Company, and the irrigation company was awarded one half of the water from the tunnel through a Supreme Court ruling in 1902 (4). In 1912, construction was completed on a cement ditch to convey water from Butterfield Creek near the mouth of the canyon for irrigation use in Herriman (2). Around 1901, a townsite and mine facilities were constructed at Lark and the Mascotte tunnel was driven here for drainage and haulage of mine water and waste rock. By 1909, a concentrator mill was in operation one-half mile east of the Mascotte tunnel, depositing tailings in the Lark/Keystone drainage. In 1937, a second mill was situated immediately east of the tailings for re-treatment of the tailings. KUC conducted local removals of lead and arsenic at the Lark tailings. They were consolidated and capped and then the surface was recontoured and seeded in 1994. Other sources of water were used periodically for irrigation near Herriman. The Bastian ditch was in operation by 1909 and conveyed water from Bingham Creek to areas up gradient of Herriman. Water from Bingham Creek was conveyed with and through the Utah Apex tailings via the Bastian ditch. The lower reaches of the Bastian ditch extended almost to Butterfield Creek. The Mascotte ditch was constructed around 1942 to convey water for irrigation from the Mascotte tunnel portal to ponds located about 1000 feet north-northeast of the Lark tailings. Water from the Mascotte ponds may have been conveyed through the Bastian ditch for irrigation. Removal of contaminated soil and sediment from the Mascotte ditch and ponds, with lead and arsenic values ranging up to 12,300 ppm and 1100 ppm, respectively, was completed by KUC in 1994. The area where the Mascotte and Bastian ditches and Midas Creek merge, north of the Lark tailings, was re-graded and reclaimed along with the Lark tailings site. In an agreement in 1952 between the mining companies and the Herriman Irrigation Company, the mining companies agreed to replace water from Butterfield tunnel with Bingham tunnel water. The water was redirected from Bingham tunnel portal to an 8" pipeline and transferred to the Herriman ditch. A second 10" pipeline was installed in 1970 after a 1966 court decision that awarded Herriman Irrigation Company all water from Bingham tunnel regardless of water quality that was not used for mining, milling or leaching operations. The flow was later diverted from the pipelines to a settling pond (Dansie Pond) located on the plateau north of Butterfield Creek. Sediment settled or precipitated out from the tunnel water in this pond. The water in the pond was diverted to KUC/EEPG BHSIR.DOC 8/4/97 4.0 fields in the bottom lands, as well as fields on the plateau on both sides of Butterfield drainage. In 1987, KUC terminated the previous agreements for Bingham tunnel water usage and in 1988 began diverting Bingham tunnel water north to use in its mining and milling operations. In 1995, KUC removed the sediment from the Dansie Pond which contained up to 1280 ppm lead and 1090 ppm arsenic (3). The presence of contaminated soils in Butterfield drainage and Herriman was brought to the attention of the regulatory agencies through a study initiated by the DERR in 1994. Sediment samples from Butter field Creek contained slightly elevated lead and(or) arsenic which was fairly consistent along the Butterfield Creek drainage and in an irrigation ditch along the north side of Herriman. Further sampling by the EPA revealed contamination of sediment in the Herriman ditch and residential soil adjacent to the ditch. Map 451-T-4620 exhibits the locations of historical mining and milling sites in and surrounding Butterfield Canyon (Appendix H). SAMPLE COMPILATION The study area was divided into three zones; 1) Butterfield Canyon; 2) Butterfield Drainage Lowlands; and 3) Herriman Agricultural Land. Butterfield Canyon includes the mining areas in the headwaters and tributaries of Butterfield Canyon and the east slope of the Qquirrh Mountains north from Butterfield Canyon to Midas Creek. Butterfield Drainage Lowlands includes the low lying agricultural areas south of Midas Creek drainage to the Butter field Creek drainage and east to Herriman. Herriman Agricultural Land includes agricultural land northwest of Herriman and ditches utilized by the Herriman Irrigation System. Compilation of this data was accomplished by: Boring and sampling of 48 boreholes near the mouth of Butterfield Canyon, upstream at selected tributaries to Butterfield Creek, and at selected locations in agricultural areas northwest of Herriman; Sampling six sites in waste rock and tailings from the Queen mine and mill site and material from the bank of Butterfield Creek transported via the "Castro Blowout"; Sampling sediment at 18 sites in Butterfield Creek and selected tributaries; Sampling soil from nine sites in agricultural areas and other locations up gradient of Herriman; and Sampling two sites from the Butterfield Creek cut bank between the Saints Rest Gulch confluence and Yosemite Gulch confluence. The above samples were collected from October to December, 1996 in accordance with the Sampling and Analysis Plan (SAP), November, 1996 (Appendix A). The boring, cut bank, source, and sediment samples produced limited data and additional samples were necessary to fully characterize the soils in Butterfield Creek Canyon. Additional historic KUC/EEPG BHSIR.DOC 8/4/97 4.1 data also surfaced after the initial sampling event. Data revealed locations of historic milling sites at the Butterfield Creek/Saints Rest confluence and in Yosemite Gulch. Sixty two trench sites and 12 additional cut bank sites were sampled in January and February, 1997. The additional sampling was conducted to vertically and laterally delineate lead contaminated soils at the Saints Rest and Yosemite confluences with Butterfield Creek Canyon. The trench and cut bank soil sampling and handling procedures followed those outlined in the SAP, November, 1996 (Appendix A). Sample locations are summarized in Table 1 and are plotted on maps 451-T-4610, 451-T- 4574, 451-T-4563, and 451-T-4562 (Appendix H). Sample location maps are indexed on map 451-T-4620 (Appendix H). BOREHOLE SAMPLING 4.2 The boreholes were installed by EarthProbe Environmental of Bountiful, Utah, between October 31, 1996 and November 11, 1996. Boreholes were driven by a "GeoProbe"-type punch to depths ranging from 3 to 31 feet. All boreholes were lithologically logged and sampled. Sampling tubes consisting of high-density polyethylene (HDPE) or poly-vinyl chloride (PVC) liners were used to collect a continuous lithologic column. Composite samples were collected at one foot intervals for the top five feet in all drill holes. Below five feet, samples were composited from various depth intervals based on observations of possible mine waste, such as color or textural differences. The composited intervals, ranged from 1 to 4 feet. Borehole samples were assigned an identification number beginning with the prefix BH-DH- and followed by a number (01 through 48) and sample depth. CUT BANK SAMPLING Cut bank samples from Butterfield Creek banks were collected by scraping soil into a container with a plastic spoon after clearing the surface with a pickhoe. Samples were assigned identification numbers beginning with the prefix BH-CB- and followed by a number (01 and 14) and sample depth. Samples that have an A following the identification number indicates that the sample was collected from sloughed soil at the base of the cut bank. 4.3 MINE WASTE SAMPLING Possible source, characterization samples were collected from historic waste rock and tailings dumps from the Queen mine in Black Jack Gulch and the bank of Butterfield Creek at its confluence with Castro Gulch. Sediment samples were assigned identification numbers beginning with the prefix BH-SC- and followed by a number (01 through 06). KUC/EEPG BHSIR.DOC 8/4/97 4.4 SOIL SAMPLING Soil samples were collected from a ditch and field down gradient from the Bingham tunnel pond (Dansie Pond), Bastian ditch, and from the vicinity of the historic Revere mill in Butterfleld Canyon. Soil samples were assigned an identification number beginning with the prefix BH-SO- followed by a number (01 through 09). 4.5 SEDIMENT (STREAM) SAMPL1NG Sediment samples were collected from Butterfield Creek at locations downstream of selected tributaries on both north and south sides of the canyon, and from selected tributaries up stream of their confluence with Butterfield Creek. Sediment samples were also collected from the headwaters of Butterfield Creek upstream of any mining activities. Sediment samples were assigned an identification number beginning with the prefix BH-SE- followed by a number (01 through 18). 4.6 TRENCH SAMPLING Trench soil sample sites are located near or downstream of Saints Rest and Yosemite gulch confluences and on both north and south sides of Butterfield Creek. The trenches were excavated from three to 5.5 feet deep using a back hoe or hand shovel. Composite samples were collected from the trenches at various depth intervals based on observations of possible mine waste such as color or textural differences. Composited intervals ranged from 0.3 to 1.7 feet. Trench samples were assigned an identification number beginning with the prefix BH-DH- and followed by a number (01 through 62) and sample depth. 5.0 SAMPLING PROCEDURES 5.1 SAMPLE EQUIPMENT Samples were collected using disposable plastic or decontaminated stainless steel hand tools. These tools included the following: disposable plastic spoons, hand shovel, pick hoe, and gloves. A back hoe, hand shovels or pick hoes were used only to gain access to sample material, then, using a clean hand tool, undisturbed sample material was exposed for sample collection. Reusable sampling tools were decontaminated prior to use. 5.2 SAMPLE LOCATIONS All sample locations were identified on an aerial photograph and surveyed. Those locations outside of Butterfield Canyon were surveyed using a global positioning satellite system (GPS). Sample sites were marked in the field with a lath or wooden stake bearing the sample identification number. KUC/EEPG 6 BHSIR.DOC 8/4/97 5.3 SAMPLES Each sample was placed in a plastic ziploc bag with no preservatives and labeled with the following information: 0 0 0 Sample identification number; Initials of sampling personnel; Date and time of collection. 5.4 DECONTAMINATION All non-disposable sampling equipment was decontaminated according to the following procedures: ¯ 0 ¯ ¯ Remove gross contaminants; Wash with Alconox soap; Rinse with tap water; Triple-rinse with de-ionized water; and Repeat all or part of the procedure, if necessary. A high-pressure sprayer was used for decontamination of drilling equipment. Decontamination was conducted away from surface water bodies and the decontamination fluid was allowed to flow over the ground. No hazardous materials were generated. 6.0 ANALYTICAL RESULTS/DISCUSSION Samples were analyzed at Kennecott Environmental Laboratory (KEL) for lead and arsenic according to EPA methods, 3050B (prep and digestion) and 6010B (analysis). Sample splits were also prepared and stored at the KUC Lark warehouse for later analyses, if required. All analytical procedures were consistent with Federal Guidance Solid Waste (SW)-846 (Test Methods For Evaluating Solid Waste). Results of this investigation are located in Tables 2, 3, 4 and Appendix B. 6.1 BUTTERFIELD CANYON Analytical results for Butterfield Canyon are presented in Table 2. 6.1.1 Headwaters Sediment samples collected from the headwaters of Butterfield Creek show low levels of lead and arsenic. Spring Gulch, had slightly elevated concentrations, at 70 ppm lead and 19.8 ppm arsenic, compared to other headwater area samples. These concentrations are well below health-based or environmental screening concentrations. These slightly KUC/EEPG BHSIR.DOC 8/4/97 6.1.2 elevated concentrations may be due to past prospecting or mining activities up gradient in Spring Gulch or from naturally elevated levels of mineralization in host rock up stream of the sample location. North Tributaries Analyses indicated that the northern tributaries of St. James, Olsen, and Castro had lead and arsenic concentrations at or near background levels. Analyses of samples collected from boreholes in Queen, Saints Rest, and Yosemite gulches indicated that: 1) the Queen Gulch samples had elevated lead (2400 ppm to 4090 ppm) and arsenic (224 ppm to 469 ppm) concentrations to a depth of 7 feet; 2) three of the six boreholes in Saints Rest Gulch had elevated lead concentrations (2830 ppm to 3330 ppm ) in the top 1 or 2 feet of the profile and arsenic concentrations less than 100 ppm; 3) another of the Saints Rest Gulch boreholes indicated elevated lead concentrations (2900 ppm to 73,200 ppm) to a depth of 13 feet and arsenic concentrations below 100 ppm; and 4) three of the four boreholes in Yosemite Gulch had elevated lead (922 ppm to 91,600 ppm) and arsenic (14.4 ppm to 715 ppm) concentrations to a depth of 5 feet. Source samples collected from historic mine waste rock and tailings piles in Queen Gulch exhibited elevated lead (1280 ppm to 31,500 ppm) and arsenic (543 ppm to 3150 ppm) concentrations. The source samples exhibited low pH pastes ranging from 4.2 to 5.0. Results of cut bank samples collected along Butterfield Creek between Saints Rest Gulch confluence and Yosemite Gulch confluence indicated that eight of the 26 cut bank samples had lead concentrations > 1000 ppm (1440 to 34,200 ppm). Four of the 26 samples had arsenic concentrations > 100 ppm (129 to 511 ppm). Elevated lead concentrations occurred to depths of 1.5 to 3.9 feet below ground surface and arsenic concentrations from 1.3 to 1.5 feet below ground surface. Two cut bank sites indicated elevated lead concentrations in slough material at the base of the bank (1440 and 10,500 ppm). Results of cut bank samples collected at or down gradient of the Yosemite Gulch confluence indicated that 16 of the 23 soil samples had lead concentrations > 1000 ppm (1000 to 90,700 ppm) and 13 of the of the 23 samples had arsenic concentrations > 100 ppm (117 to 958 ppm). Elevated lead concentrations occur to depths of 0.8 to 8.0 feet below ground surface. Elevated arsenic concentration occur to depths of 0.8 to 4.6 feet below ground surface. Four cut bank sites indicated elevated lead concentrations in slough material at the base of the bank (1000 to 78,500 ppm). Results from trench samples collected at Saints Rest Gulch confluence down gradient to the Yosemite Gulch confluence indicated that 23 of the 72 samples have lead concentrations > 1000 ppm (1140 to 65,900 ppm). Six of these samples had arsenic concentrations > 100 ppm (102 to 456 ppm). Elevated lead concentrations range in depth from 0.5 feet to 3.4 feet and arsenic concentrations from 0.6 to 2.3 feet below ground surface. Results from trench samples collected at or down gradient of the Yosemite Gulch KUC/EEPG BHSIR.DOC 8/4/97 6.1.3 confluence indicated that 37 of the 70 samples have lead concentrations > 1000 ppm (1030 to 86,000 ppm). Eighteen of the 70 samples have arsenic concentrations > 100 ppm (111 to 602 ppm). Elevated lead and arsenic concentrations range in depth from 0.4 feet to 5.5 feet below ground surface. South Tributaries 6.1.4 6.2 Sediment samples collected from southern tributaries exhibit low levels of lead and arsenic. The highest concentrations are 150 ppm lead and 16.6 ppm arsenic. Butterfield Creek Sediment samples collected from the Butterfield Creek bed downstream from confluences with Saints Rest and Yosemite drainages exhibited lead and arsenic concentrations at or below background levels (610 ppm lead and 30.8 ppm arsenic). The higher concentration are attributed to slough material from Saints Rest and Yosemite drainages that was carried down stream and redeposited in the creek bed. BUTTERFIELD DRAINAGE LOWLANDS Analyses indicated that the highest lead concentrations (247 ppm to 1300 ppm) at the mouth of the canyon are located in the top 1 foot of soil. All arsenic concentrations are well below 100 ppm. Butterfield Drainage Lowlands lead and arsenic concentrations are listed in Table 3. These samples were collected from Butterfield Canyon in an alfalfa field immediately up gradient from Highway 111. Soil collected from nine of the 12 boreholes in the bottom lands along Butterfield Creek exhibited elevated lead concentrations (186 ppm to 1190 ppm) in the top 1 or 2 feet of the profile (BH-DH-16 through BH-DH-19 and BH-DH-23 through BH-DH-27). Arsenic concentrations were < 100 ppm. The other three boreholes exhibited elevated lead (1230 ppm to 3540 ppm) and arsenic (113 ppm to 184 ppm) concentrations to depths of 4, 7, and 9 feet, respectively (BH-DH-20 through BH-DH-22). See Table 3 for details. Soil samples collected in the bottom lands (BH-SO-01 and BH-SO-02) indicated elevated lead (932 ppm to 1970 ppm) and arsenic (79.9 ppm to 295 ppm) concentrations. Soil samples collected on the plateau (BH-SO-06 and BH-SO-07) indicated lead concentrations below 660 ppm and an elevated arsenic concentration at 382 ppm. Soil profiles that exhibit deeper (4, 7, and 9 feet below ground surface) elevated lead and arsenic concentrations are located in historic ponds that have been filled with stream sediment. Elevated lead and arsenic concentrations on the surface (1 or 2 feet below ground surface) are probably caused by irrigation water carrying sediments which settled out. KUC/EEPG BHSIR.DOC 8/4/97 6.3 HERRIMAN AGRICULTURAL LOWLANDS Analyses of soil samples collected from boreholes in lower Butterfield ditch exhibited a slightly elevated lead (733 ppm) concentration in the top one foot of soil. All other lead and the arsenic concentrations were near background. Herriman Agricultural Land lead and arsenic concentrations are listed in Table 4. Only one of the ten boreholes sampled on Bastian field and in the Bastian ditch system exhibited elevated lead concentrations (1100 ppm to 2420 ppm) in the top 1.7 feet of soil. This sample was collected at the intersection of Butterfield ditch and Bastian ditch. All other lead and arsenic concentrations were at or near background. This sample was collected at the intersection of Butterfield ditch and Bastian ditch. Samples collected from boreholes on upland agricultural lands exhibited lead and arsenic concentrations at or near background, averaging 31 ppm lead and 18.7 ppm arsenic. Analyses for lead and arsenic indicate that the soils from the Herriman agricultural land are either background or slightly above background. The highest lead and arsenic concentrations in Butterfield ditch tend to be located in the top one foot of soil. Elevated lead and arsenic concentrations on the surface are probably caused by irrigation water carrying sediments which settled out, up gradient erosion and re-working and concentration of heavy metals in surface soils. 7,0 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC) Kennecott Environmental Laboratory (KEL), Magna, Utah, was the primary analytical laboratory, and Mountain States Laboratory (MSL), Salt Lake City, Utah was the secondary laboratory. Both laboratories are State certified and as such follow QA/QC procedures consistent with EPA standards. Laboratory QA/QC samples include method blanks, matrix spikes, duplicates, and matrix duplicates, and calibration and calibration check samples. Copies of the laboratory quality control reports were reviewed on a regular basis. QA/QC procedures included splitting 10 percent of the soil samples collected and submitting these to the EPA (44 samples). One in every 15 samples (6.6%) was split and sent to a second laboratory (21 samples). Soil samples were homogenized before splitting by shaking the bag and breaking all clumps by hand, then pouring ½ of the sample into a labeled ziploc bag. Accuracy is a determination of how close the measurement is to the true value, assessed via spike recovery in sample matrices and blanks and performed by the laboratory as part of their QA/QC procedures. Spike recoveries reported by the laboratories should be within 20 percent of the spiked amount. Completeness is a measure of the amount of valid data obtained, compared to the amount that was expected under normal conditions. Ninety (90%) percent completeness was the goal of this investigation. KUC/EEPG 10 BHSIR.DOC 8/4/97 Two rinsate samples were collected from decontaminated sampling tools. Rinsate analyses are located in Appendix C. All water samples were preserved with nitric acid to a pH of < 2. Rinsate results indicated values at the minimum detectable limits (0.005 mg/L) or below. Results of the 21 split samples analyzed by a second laboratory (MSL; Appendix B) were compared to the results from KEL by calculating the relative percent difference (RPD). The RPD is defined as: 8.0 RPD = (A 1-A2)/((A 1 +A2)/2)* 100 A1 = Analytical results from primary sample A2 = Analytical results from confirmation sample The data quality objective for this comparison was :k 35%. Data that exceeds RPDs in excess of 35% may still however be considered usable if the analyte is detected in quantities less than 10 times the detection limit. Table 5 lists the RPD values calculated from the primary lab (KEL) and the secondary lab (MSL) results. Thirty of these results exceed the required RPD (35%). However, 25 of these RPDs are below a concentration that raises concern. The five remaining samples exceeding 35% may be due to the inhomogenous composition of the soils sampled.

APPENDIX A LAST HOLDOUT LLC (Bastian Pasture)- SOIL MITIGATION SUMMARY (SUMMARY OF FLOOD SEDIMENT CLEANUP ON BASTIAN PROPERTY) RIO TINTO KENNECOTT UTAH COPPER 2014 Property)- Kennecott Utah Copper 4700 Daybreak Parkway South Jordan, Utah 84095 Introduction Storm related sediments washed down Butterfield Creek on September 13-14, 2013. Some of the sediments which contained elevated concentrations of lead and arsenic flowed onto Bastian property (The Last Holdout LLC) in portions of Sections 32 and 33, Township 3 South, Range 2 West, SLBM (Exhibit A). Rio Tinto Kennecott (RTKC) received permission from Dave Bastian to map and sample the deposited storm sediments in September 2013 and entered into an agreement April 4, 2014 for access to use two areas for desilting purposes and to clean up or till in the September 2013 storm sediments. For this report, sampling results do not include the post-removal sampling conducted on the Butterfield Creek banks. Location of Storm Sediments The storm sediments were deposited in an along Butterfield Creek. From west to east, the sediment deposited in an irrigation turn-out/storage area on the west end of the property which overflowed and covered approximately 1.2 acres of a grass field south of the Bastian farm buildings. It also flooded outside of the creek banks across the entire property and east of the Bastian Farm, the sediments flowed out of the creek over Highway 111 and into the wheat field at four locations covering approximately 7.54 acres (Exhibit A). Mapping and Sampling RTKC mapped the locations of the storm sediment and collected samples at five sites. The mapping and sampling locations were captured with GPS (Exhibit A). At the five sites, the storm sediment could readily be differentiated from the underlying soil as it was yellow brown silt and clay as compared to the dark brown to black native silty sandy soil. Four samples were collected at each of the five sites with the upper-most sample of the storm sediment, which ranged from ¼ to ½ inch thick, then a sample from 0-2 inches below the storm sediment, 2-4 inches and 4-6 inches below the storm sediment. All samples were sent to RTKC’s Environmental Lab KEL) for analysis with focus on lead and arsenic. Results are listed in Table 1. The results of the sampling were then provided to Dave Bastian. Based upon the results and the soil agricultural characteristics for native soil of the property, several reasonable options were discussed with Dave Bastian. The option selected included storm sediment removal for Mr. Dave Bastian 14 July 2014 Page 2 areas where very little native soil (< 6 inches) existed and tilling for those areas that have thick (> 6 inches) native soil cover. Areas that had soil removal work also received backfill soil. Sampling was conducted for the post-removal surface and also for the areas tilled. For the post-removal areas, composite samples were collected from 0-2 inches and for the areas tilled, samples were collected at each of the five original sites and collected from 0-2 inches, 2-4 inches and from 4-6 inches. Results of this sampling are presented in Table 1 along with the pre-tilling samples. In addition to the soil mitigation work on Bastian property for the pasture and wheat fields, RTKC also conducted soil removal, sampling and backfill along Butterfield Creek. This work included removing soil up to approximately 25 feet on either side of the creek. Butterfield Creek passes through Bastian’s barn lot and east through a pasture field and then crosses Highway 111 and proceeds east within the County road right-of-way to the starting point of the Herriman Irrigation Pipeline. Sampling results and detailed reporting for the Butterfield Creek banks are not included with this summary but will be included with the report for Butterfield Creek soil clean up.

Four areas were targeted for soil removal in the wheat field east of the Bastian farm buildings along with the irrigation turnout basin south of Highway 111 (Map 1). The wheat field areas where soil was removed included approximately 2.02 acres and the turnout basin included a ditch approximately 125 feet long and 8 feet wide. A total of 72 loads (864 cyds) was hauled to RTKC’s Blue Water Repository and 140 loads (1680 cyds) of clean soil was brought back to the wheat field area. The remaining acreage, excluding Butterfield Creek banks which were also cleaned, were tilled and no soil removed including 5.52 acres in the wheat field and 1.2 acres of the pasture. After storm sediment was removed with a track-hoe and 10-wheeled dump trucks from the wheat field and turnout basin, six post-removal composite samples were collected (Map 1) and one post-removal sample collected from the irrigation turnout. Post-removal data is included in Table 2.

Prior to loading and hauling, the sampling personnel used an X-Ray Floresence (XRF) for field screening and a composite sample was collected and analysed at KEL for lead and arsenic. The lab sample had 51 ppm lead and 13 ppm arsenic. About twice as much clean backfill soil was placed on the removal areas in the wheat field as compared to the soil removed. Mr. Dave Bastian 14 July 2014 Page 5 Access to Soil Removal and Clean Up Areas Access to the wheat field area was through a fence gap directly off of Highway 111 approximately 250 feet west of where Butterfield Creek crosses from south to north across Highway 111. Four to eight inch rock was placed through the fence gap after replacing the 14 inch concrete pipe/culvert with a 14 inch HDPE (plastic) pipe. The replaced pipe is approximately 20 feet long. After the removal and backfill was complete, the coarse rock that was placed over the culvert was removed to a distance of approximately 5 feet north of the culvert. RTKC was notified by Dave Bastian that the remaining rock was still encroaching on the wheat field so addition coarse rock was removed to a distance of approximately 3 feet north of the placed pipe. Access to the existing irrigation turnout was along an existing road located south of the farm buildings and access to the east desilting tanks was along the existing farm road on north side of wheat field and then south and west from the eastern portion of the property. Removal and transport of the tanks was along the same access. After the tanks were removed, stockpiled clean import soil (same as placed on wheat field) was placed in the excavation areas that housed the desilting tanks. Access to Butterfield Creek was through an existing gate on eastern portion located south of Highway 111 and also through the corals and the UP&L road. Coarse rock was exposed for some portions of Butterfield Creek and for these area, imported soil was placed, again the same soil type as placed in the wheat field. Reseeding For all of the non-wheat field areas, seed was broadcast with a hand-seed implement. The areas seeded included the banks of Butterfield Creek, the access trail along Butterfield Creek and the 1.2 acres located adjacent and south of Butterfield Creek immediately downstream of the irrigation turnout basin. The seed mix included crested wheatgrass (Nordan), siberian wheatgrass (Vavilov II), slender wheatgrass (First Strike), western wheatgrass (Rosana or Arriba) and California Poppy. The application rate was 20 lbs/acre. Miscellaneous RTKC contractors rented a tractor to conduct the till work. Dave Bastian provided a 16 foot disc. Areas tilled included the approximate south third of Bastian’s wheat field and also the RTKC property on the north side of Butterfield Creek adjacent and south of the County Road in the canyon mouth. Several gates contained Dave Bastian locks and keys to the locks were provided. RTKC returned the keys after the work was completed.

Decontamination procedures will be established for each site based on the contaminants of concern to be sampled and the degree of hazard associated with the site. Decontamination procedures will be reviewed and approved by the Site Health and Safety Manager. The following procedure contains standard decontamination protocols, suitable for most sites. All non-disposable sampling equipment will be decontaminated prior to use and between samples as follows: · Remove Gross Contaminants – Equipment will be scrubbed using a water/detergent solution and stiff brush until visible contaminants are removed. The water will be changed as necessary, daily at a minimum. · Wash with Alconox soap or similar detergent – An Alconox wash will be prepared as indicated on the product labeling, typically mixing 1 to 1.5 tablespoons of Alconox per gallon of water. The water will be changed as necessary, daily at a minimum. · Water Rinse – Equipment will be rinsed with clear potable water. The water will be changed as necessary, daily at a minimum. · Deionized Water Rinse – Deionized water will be used as a final rinse for all equipment. The water may be poured or sprayed, or the equipment submerged. · Gloves – Sampling personnel will change into a new pair of chemical-resistant gloves between samples and discard the previous pair. The backhoe bucket will be decontaminated prior to use using a high-pressure washer. Decontamination water will be dispersed on the ground surface and allowed to infiltrate near the source. Between trench/sample locations, the backhoe bucket will be shaken and/or swept to remove loose dirt. SAMPLE COLLECTION Sample containers, preservation techniques and holding times will be consistent with EPA SW-846 guidelines. Soil samples to be analyzed for metals will be placed in plastic Ziplock bags. No preservation or sample cooling is necessary for lead and arsenic analysis and the holding time is 6 months. Sample intervals will be selected based on the project sampling plan. Soil samples will be collected using disposable plastic or decontaminated hand tools. These tools may include one or more of the following: · Disposable plastic spoon, trowel or cup · Stainless steel spoon, trowel or cup · Clean, disposable gloves (vinyl, latex, nitrile) )]Q Z # 20213493.001A/DRAFT Page A-2 May 7, 2021 © 2021 Kleinfelder www.kleinfelder.com KLEINFELDER 849 West Levoy, Suite 200, Salt Lake City, UT. 84123 p | 801.261.3336 Only disposable plastic or decontaminated stainless-steel tools will be used to sample the material. Reusable sampling tools will be decontaminated prior to use following the procedures described in the “Equipment Decontamination” SOP. Grab Samples A soil sample will be collected at the selected depths with a spoon, trowel, or chemical-resistant gloves. The material will be screened with the appropriate direct reading instrument, such as a PID or XRF, and the reading will be recorded on the log form or in the field notebook. The portion of the sample collected for chemical analysis will be transferred immediately into the appropriate sample container using decontaminated equipment, clean disposable spoons or equipment, or by hand wearing new disposable chemical-resistant gloves. Avoid gravels and rock fragments when filling soil sample containers. If the sample is to be analyzed for volatile organics, the container will be completely filled with soil to minimize headspace. The container will be labeled appropriately and immediately stored in an iced cooler to maintain a temperature of 4° Celsius (if cooling is required for the analytical method). Composite Soil Samples Composite samples will be prepared by placing equal amounts of soil in a stainless-steel bowl or clean plastic bag using a stainless-steel spoon or by hand wearing new chemical-resistant gloves. The composite sample will be comprised of a minimum of five aliquots. The sample will be homogenized with a stainless-steel spoon or gloved hand. The homogenized soil will be packaged in a laboratory-supplied sample container, labeled appropriately, and placed in an iced cooler to maintain a temperature of 4° Celsius, if appropriate for the analytical method. Enough soil will be collected for each sample to allow for additional laboratory analysis of lead and arsenic if necessary. The samples will be held at the laboratory for 30 days after analysis to accommodate possible additional analysis. Soil sample material will be homogenized prior to analysis. The sample will be placed in a new, re-sealable plastic bag. Large debris and rocks will be removed, and the sample will be homogenized by kneading the soil within the bag. Clay soils, if encountered, will be thoroughly mixed to the extent practicable.

STANDARD OPERATING PROCEDURES EQUIPMENT DECONTAMINATION Decontamination procedures will be used to prevent cross-contamination of samples. Decontamination procedures will be established for each site based on the contaminants of concern to be sampled and the degree of hazard associated with the site. Decontamination procedures will be reviewed and approved by the Site Health and Safety Manager. The following procedure contains standard decontamination protocols, suitable for most sites. All non-disposable sampling equipment will be decontaminated prior to use and between samples as follows: • Remove Gross Contaminants – Equipment will be scrubbed using a water/detergent solution and stiff brush until visible contaminants are removed. The water will be changed as necessary, daily at a minimum. • Wash with Alconox soap or similar detergent – An Alconox wash will be prepared as indicated on the product labeling, typically mixing 1 to 1.5 tablespoons of Alconox per gallon of water. The water will be changed as necessary, daily at a minimum. • Water Rinse – Equipment will be rinsed with clear potable water. The water will be changed as necessary, daily at a minimum. • Deionized Water Rinse – Deionized water will be used as a final rinse for all equipment. The water may be poured or sprayed, or the equipment submerged. • Gloves – Sampling personnel will change into a new pair of chemical-resistant gloves between samples and discard the previous pair. The backhoe bucket will be decontaminated prior to use using a high-pressure washer. Decontamination water will be dispersed on the ground surface and allowed to infiltrate near the source. Between trench/sample locations, the backhoe bucket will be shaken and/or swept to remove loose dirt. SAMPLE COLLECTION Sample containers, preservation techniques and holding times will be consistent with EPA SW-846 guidelines. Soil samples to be analyzed for metals will be placed in plastic Ziplock bags. No preservation or sample cooling is necessary for lead and arsenic analysis and the holding time is 6 months. Sample intervals will be selected based on the project sampling plan. Soil samples will be collected using disposable plastic or decontaminated hand tools. These tools may include one or more of the following: • Disposable plastic spoon, trowel or cup • Stainless steel spoon, trowel or cup • Clean, disposable gloves (vinyl, latex, nitrile) 20210351.001A/SLC22R147484 Page B2 of B3 December 6, 2022 © 2022 Kleinfelder www.kleinfelder.com Only disposable plastic or decontaminated stainless-steel tools will be used to sample the material. Reusable sampling tools will be decontaminated prior to use following the procedures described in the “Equipment Decontamination” SOP. Grab Samples A soil sample will be collected at the selected depths with a spoon, trowel, or chemical-resistant gloves. The material will be screened with the appropriate direct reading instrument, such as a PID or XRF, and the reading will be recorded on the log form or in the field notebook. The portion of the sample collected for chemical analysis will be transferred immediately into the appropriate sample container using decontaminated equipment, clean disposable spoons or equipment, or by hand wearing new disposable chemical-resistant gloves. Avoid gravels and rock fragments when filling soil sample containers. If the sample is to be analyzed for volatile organics, the container will be completely filled with soil to minimize headspace. The container will be labeled appropriately and immediately stored in an iced cooler to maintain a temperature of 4° Celsius (if cooling is required for the analytical method). Composite Soil Samples Composite samples will be prepared by placing equal amounts of soil in a stainless-steel bowl or clean plastic bag using a stainless-steel spoon or by hand wearing new chemical-resistant gloves. The composite sample will be comprised of a minimum of five aliquots. The sample will be homogenized with a stainless-steel spoon or gloved hand. The homogenized soil will be packaged in a laboratory-supplied sample container, labeled appropriately, and placed in an iced cooler to maintain a temperature of 4° Celsius, if appropriate for the analytical method. Enough soil will be collected for each sample to allow for additional laboratory analysis of lead and arsenic if necessary. The samples will be held at the laboratory for 30 days after analysis to accommodate possible additional analysis. Soil sample material will be homogenized prior to analysis. The sample will be placed in a new, re- sealable plastic bag. Large debris and rocks will be removed, and the sample will be homogenized by kneading the soil within the bag. Clay soils, if encountered, will be thoroughly mixed to the extent practicable. Sample Identification and Labeling To prevent misidentification of samples each sample container will be labeled with indelible ink. The following information will be recorded on the sample container: • Project name or number • Sample identification number • Sample depth • Date and time of collection Samples will be transported in laboratory-supplied coolers and stored on ice to maintain a temperature between 2 and 6 degree Centigrade, if sample cooling is required for the analytical method.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. 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. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. 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 E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL). J3 The associated batch QC was outside the established quality control range for precision. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. 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 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1216358 05/18/20 14:38 147 of 161 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1216358 05/18/20 15:55 147 of 161 ONE LAB.

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. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. 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 J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. 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 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1220518 05/28/20 14:55 40 of 44 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1220518 05/28/20 16:22 40 of 44 ONE LAB.

NATIONWIDE.CASE NARRATIVE All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times, unless qualified or notated within the report. Where applicable, all MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. 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. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. 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. 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. O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1232707 07/01/20 10:04 170 of 185 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1232707 07/01/20 10:39 170 of 185 ONE LAB.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. 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. 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 O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1242936 07/30/20 19:29 94 of 108 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1242936 07/31/20 13:55 94 of 108 ONE LAB.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. 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. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. 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 The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1244439 08/05/20 11:57 10 of 12 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: GSC/Kleinfelder - SLC 20210351 L1244439 08/05/20 13:10 10 of 12 ONE LAB.
