Read more DSHW-2023-211360 _6479224.2 RESPONSES TO COMMENTS (RTC) FROM UDEQ-DWMRC Site Characterization Completion Report for Recycled Earth South Property The comments provided by the Utah Department of Environmental Quality, Division of Waste Management and Radiation Control (Division) dated October 5, 2023, are copied below, with responses to the comments prepared by Tetra Tech on behalf of Recycled Earth provided in blue font. These responses are provided to accompany the revised Site Characterization Completion Report for Recycled Earth South Property (Report) to be concurrently re-submitted to the Division. 1. Section 1.0 Introduction The first paragraph states that a singular discharge was received from one Recycled Earth customer. This discharge is described as responsible for an odor, leading to Ogden City’s subsequent investigation, and the Division’s request for investigation of any potential contamination from disposal of unauthorized liquid wastes on the site. According to records provided to Ogden City and the Division by Recycled Earth of historical releases at the site, there were several liquid waste loads accepted from multiple customers between February and August 2022. Any one or several of these accepted liquid waste disposals could have caused the purported contamination. Please update the report to reflect this information. Response: The indicated text has been revised in the Report as directed by DWMRC. However, the Division’s assertion that the contamination could have come from customers other than Beck Sanitation Inc. (BSI), is inaccurate. Recycled Earth has obtained evidence proving that BSI was the only customer who offloaded wastewater at the South Property. Recycled Earth is litigating its claims against BSI in the district court. 2. Section 1.2 Historical Releases Again, throughout this section, a singular release has been identified as the cause of the odor and subsequent investigations by Ogden City and the Division. Additionally, the third paragraph of this section states that Ogden City and the Division identified an unauthorized release by the singular customer as the cause in their respective Notice of Violation and Request. This is not correct; neither Ogden City nor the Division have identified a singular disposal as the primary interest in this investigation. It is the Division’s understanding that Recycled Earth LLC did not know the nature of accepted liquid waste loads and that there were multiple loads from multiple customers. A responsible party should not be named without sufficient records that characterize the waste received all parties that disposed of liquid waste at Recycled Earth LLC. Please update the report to reflect this information. Response: See Response No. 1. However, Section 1.2 has been revised to reflect the language presented in the Site Characterization Plan that was originally approved by the Division and Ogden City. 3. Section 2.1.3 Catch Basin Cleanout, Section 2.1.4 Excavation Near Maintenance Building Please provide waste manifests for the catch basin cleanout and the excavation near the maintenance building. _6479224.2 Response: Waste manifests for the catch basin cleanout and excavation near the maintenance building have been added to Appendix A of the Report. 4. Section 3.3.1 French Drain Sample Results In the Division’s December 5, 2022, letter (DSHW-2022-026972) that detailed comments on the site characterization plan, the Division states “For future soil and water analysis, please note that the Division does not recognize the use of the Division of Environmental Response and Remediation (DERR) Initial Screening Levels (ISL) for soil and groundwater. In lieu of that, the acceptable screening standards for all media of concern will be the US EPA Regional Screening Level, (EPA RSLs).” Please update the Site Characterization Report to use EPA RSL’s for French drain groundwater sample results. Response: Recycled Earth’s technical consultant Tetra Tech and legal counsel Dentons Durham Jones Pinegar strongly oppose application of the Tap Water RSLs because there is no current or anticipated future use of groundwater as tap water at the South Property and because shallow groundwater at the south property and all other properties along the Wasatch Front is not a suitable for drinking water and cannot be used for this purpose without extensive treatment to remove high concentrations of total dissolved solids (TDS). The only water-related screening levels on the EPA RSLs are for drinking water, i.e., Tap Water levels and Maximum Contaminant Levels (MCLs). However, Recycled Earth agrees to add the MCLs to Table 6. Recycled Earth recognizes that there is no MCL or Utah Groundwater Quality Standard for TPH-DRO. As a conservative approach and at the direction of the DWMRC, EPA Tap Water RSLs were added to the Report for screening purposes for indicator compounds specified in Table 5 of the Division’s Technical Guide for Risk Assessments Section 5.2.7. The Guide states that risk from TPH should be evaluated by assessing individual chemical constituents rather than relying on TPH fraction data. All french drain groundwater detections were below the MCLs and Tap Water levels for the indicator compounds except for arsenic. We have revised The Report text and Table 6 to reflect this comparison and the prior references to the ISLs have been removed as directed. Background concentration for arsenic will be further evaluated per the method to be presented in the forthcoming Site Management Plan. 5. Section 3.4.2 Groundwater Sample Results In the Division’s December 5, 2022, letter (DSHW-2022-026972) that detailed comments on the site characterization plan, the Division states: “For future soil and water analysis, please note that the Division does not recognize the use of the Division of Environmental Response and Remediation (DERR) Initial Screening Levels (ISL) for soil and groundwater. In lieu of that, the acceptable screening standards for all media of concern will be the US EPA Regional Screening Level, (EPA RSLs).” Please update the Site Characterization Report to use EPA RSL’s for groundwater sample results. Response: Recycled Earth’s response to this comment is the same as for Response No. 4. Table 11 has been revised to include conservative comparisons of results to the MCLs and EPA Tap Water RSLs for TPH indicator compounds. All groundwater detections were below the MCLs and Tap Water levels for the indicator compounds except for arsenic and manganese. Background concentrations for arsenic and _6479224.2 manganese will be further evaluated per the method to be presented in the forthcoming Site Management Plan. 6. Section 3.6 Conceptual Site Model According to Utah Administrative Code (UAC) R315-101-5 (d), the conceptual site model shall include a determination as to whether or not any potential exposure pathways for subsurface soils are complete under both current and anticipated future conditions. For any exposure pathways that have a reasonable potential for being complete, associated risks shall be evaluated. Section 2.3 of the report states that the French drain invert depth, where sample FD-1 was taken, is approximately five feet below ground surface. Utah Administrative Code R315-101-5 (d)(3) describes that the soil exposure interval applicable to the construction worker is defined as surface down to depth of construction of ten feet below ground surface. Because the French drain soil depth is within surface down to ten feet below ground surface, the exposure pathway has reasonable potential for being complete. Therefore, to protect workers on any future construction activity at the site, please update the Site Characterization Report to include evaluated risks associated with contaminant exposure depth from surface to ten feet below ground surface. Response: Based on this comment, Recycled Earth completed further remediation by excavating soils from the area of french drain soil sample FD-1. This work was performed as described in email correspondence sent by Tetra Tech to the Division on October 13, 2023. A description of this work and the results from confirmation sampling after soil removal have been added to Section 3.3.1 of the Report. Because the three confirmation sample results collected from the excavation floor and sidewalls showed arsenic concentrations below the established background concentration of 15 mg/kg, there is no remaining exposure pathway for subsurface soils and no further assessment or remediation is required for this area. 7. Section 4.1 Summary of Findings As detailed in Number 6 above, the conceptual site model should indicate the risks associated with French drain sample FD-1 arsenic levels from ground surface to ten feet below ground surface. The Summary of Findings section should be updated to detail any necessary remediation or additional sampling needed for the mitigation of those risks, to occur before site closure. Bullet three in Section 4.1 states that data suggests the elevated arsenic detections in groundwater at the site are naturally occurring. Although this may be accurate, variations in groundwater arsenic levels downstream from MW-1 indicate an increase in arsenic levels within the site. Arsenic groundwater background concentration should be established, and further groundwater monitoring and analysis must occur, to make this, or any other groundwater determination. Arsenic groundwater background concentration should be established through upgradient groundwater sampling and further on-site groundwater monitoring shall be used to establish constituent concentration trends to determine if arsenic or other groundwater constituents are shown to be above background concentration. For any on-site constituent concentrations shown to be above background, _6479224.2 potential contamination of downstream resources (i.e., the site storm system if the French drain is reconnected, the Hooper Water Improvement District, and any other potential contamination source downstream from the site) should then be addressed. A plan for future groundwater monitoring and analysis, including background constituent determinations and monitoring objectives, should be included as an attachment in the upcoming Site Management Plan. Please note, for the proposed future groundwater monitoring, the constituent standards should be the U.S. EPA Total Petroleum Hydrocarbons Diesel Range Organics (TPH DRO) RSL standard (ensuring that the analytical method to be used is consistent with the U.S. EPA TPH DRO analytical Method for applicability) or a semi-volatile organic compounds (SVOC) analysis to represent the TPH DRO should be used. The standards for the SVOC constituents detected in groundwater are available in the EPA RSL Table and are listed as the maximum contaminant level (MCL) values. If the MCL value is not available, the default value shall be the Tap Water value. If both values are available, the greater of the two values shall be the standard. See the Division’s Technical Guide for Risk Assessments Section 5.2.7. for further instructions. Response: Recycled Earth has revised Section 4.2 of the Report to include a plan for future groundwater monitoring and background constituent determination for arsenic in the forthcoming SMP; and based on conservative comparison of groundwater results to the EPA Tap Water RSLs for TPH indicator compounds, manganese will require similar evaluation. Arsenic and manganese concentrations in the south property groundwater will be further evaluated to develop site-specific background values per the method to be presented in the forthcoming SMP. 8. Section 4.2 Recommendations Recommendations should reflect the changes made in the Conceptual Site Model and Summary of Findings sections. This may include, but is not limited to, further sampling and remediation of soil from ground surface to ten feet at the French drain FD-1 sample area before site closure. Response: Section 4.2 has been updated to reflect the further remediation through soil excavation and removal at the FD-1 sample location. Confirmation samples results and supporting information about this remediation work are provided in a new Appendix H in the Report. 9. Tables Table 6 – French Drain Sample Detections and Table 11 – Groundwater Monitoring Well Sample Detections should include EPA RSLs. Response: Please Response No. 4. Tables 6 and 11 have been updated to include the TPH indicator compounds listed in Table 5 of the Division’s Technical Guide for Risk Assessments Section 5.2.7. 10. Figures Please verify the depth of monitoring well MW-1; the depth specified in Figure 10 may be a typo. _6479224.2 Response: Please note that Figure 10 presents groundwater elevations, not depths. The legend has been revised for clarity on this matter. 11. In addition, a reminder that an updated plan of operations for Recycled Earth South Property must be submitted to the Division. Currently, construction and demolition (C&D) wastes are approved to be received at the recycling facility, located on the north property of Recycled Earth, for recycling purposes only. The management of C&D wastes on the southern campus, along with the unauthorized dumping of liquid wastes, has not been reviewed or approved by the Division. The updated plan of operations does not need to be included in the revised Site Characterization Report, but any changes to the facility’s operation or construction resulting from the site investigation, characterization, and management plan must be reflected in the updated plan of operations. Response: An updated Plan of Operations will be prepared and provided to DWMRC by Recycled Earth; it will be submitted separately from the Site Characterization Report. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response 1 The NOV was issued by Ogden City Public Services on September 30, 2022 for a purported illicit discharge on the Site by one of Recycled Earth’s customers to the Ogden City Municipal Storm Sewer System (MS4). This phrase should be deleted. The NOV made no reference to Beck SanitaƟon as the illicit discharge source, as this sentence implies. The indicated text has been deleted from the Site CharacterizaƟon Report (Report). 2 According to Recycled Earth, Recycled Earth, no significant spills or releases have occurred at the Site. Add "prior to the August 2022 illicit discharge." The requested text has been added to the Report. 3 Except for the purported release of unauthorized liquid waste by Beck’s SanitaƟon, Inc. idenƟfied by the City and UDEQ in their respecƟve NOV and Request as described previously and described in the Ɵmeline below, Recycled Earth is unaware of other significant releases on or from the Site. Delete this phrase as it implies that the NOV idenƟfied Beck SanitaƟon as responsible for the illicit discharge, which the NOV does not do. The indicated text has been deleted from the Report. It was not Recycled Earth’s intenƟon to suggest that Beck SanitaƟon Inc. (BSI) was idenƟfied in the NOV, but rather the original language was to document which Recycled Earth customer had discharged impacted water to the south property and was ulƟmately responsible for the contaminaƟon. Recycled Earth has obtained evidence proving that BSI was the only customer who offloaded wastewater at the South Property. Recycled Earth is liƟgaƟng its claims against BSI in the district court. 4 August 24: 2022 - Ogden City terminated Recycled Earth's access to the MS4 due to the detecƟon of illicit discharge of pollutants or water containing pollutants to the MS4 by Beck’s SanitaƟon, Inc. Revise to "suspended Recycled Earth's access to the MS4 for 30 days. . ." Ogden City has never terminated Recycled Earth's access to the MS4. The City suspended access for 30 days on 8/24 and the 9/30 NOV suspended access indefinitely, pending compliance with the City's orders. The indicated text has been revised in the Report as requested. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response 5 The released water flowed into Ogden City’s off-Site detenƟon pond and overflowed into the City’s MS4. Revise to "Recycled Earth's detenƟon pond on the north side of the Site ("SE-Pond"). During this incident, water flowed through Recycled Earth's storm water system into the SE-Pond which overflowed into the City's MS4. As shown in the figures aƩached to this report and in public records, the SE-Pond is on Recycled Earth's property. The City has an easement to access the SE-Pond but does not own the pond. The text has been revised in the Report to reflect Recycled Earth’s ownership of the detenƟon pond. 6 Upon acceptance of these results set forth in this Report, Tetra Tech recommends that Ogden City remove the plug and allow Recycled Earth to resume at the Site storm water discharges to the MS4 Ogden City will allow Recycled Earth to resume storm water discharges to the MS4. However, Recycled Earth will be required to idenƟfy and test all liquid retained on Site proposed to be discharged to confirm it meets appropriate water quality standards prior to reconnecƟon. Furthermore, upon reconnecƟon, Recycled Earth will be required to test the storm water discharge at Ouƞall #1 (See Figure 2) at least quarterly for 3 years. Only the previously approved storm water system on Site may be reconnected. The perforated pipe systems were never approved by Ogden City. Recycled Earth submiƩed to Ogden City on October 24, 2023, a “Request for Reinstatement of Storm Water MS4 ConnecƟon,” and is working with Ogden City to complete this process consistent with this comment. No revisions are required for the Report in connecƟon with his comment. 7 The released water flowed into Ogden City’s off-Site detenƟon pond and overflowed into the City’s MS4. While there is an easement dedicated to OC for this detenƟon basin, the basin is owned and operated by RE. See Response to Comment 5 8 Recycled Earth appealed the Second NOV, and the appeal is currently pending before the Ogden City Mayor. A leƩer from the Ogden City Mayor is coming soon. Acknowledged. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response 9 It is anƟcipated that upon acceptance of the site characterizaƟon results and the resumpƟon of discharges to the MS4 that the french drain will be reconnected to the storm water system in cooperaƟon with Ogden City, and the temporary detenƟon basin will be filled and eliminated as a Site feature. Ogden City has not permiƩed and will not permit the french drain to be reconnected for these reasons: 1. The original connecƟon of this french drain was done without approval. Ogden City does not have any site plan or permiƫng records on file showing original approval of the installaƟon of this french drain and the City would not permit such a connecƟon. 2. ReconnecƟng of the french drain would result in discharge of Site groundwater into Ogden MS4 and waters of the state. Concern for groundwater contaminaƟon on site is warranted based on the following informaƟon: •The established need to sample groundwater again in December 2023 to re- evaluate arsenic and TPH DRO concentraƟons in the groundwater at the Site. •The established need to develop a Site Management Plan which restricts use of, and requires worker protecƟon and management during work in, shallow groundwater. •Table 6: All water samples taken along the french drain show exceedances against UDEQ Groundwater Quality Standards for the following analyte. oFD-1: Arsenic oFD-2: Arsenic The french drain has been further excavated in the vicinity of Sample FD-1 to remove the arsenic affected soil. The Report has been revised to present supplemental soil confirmaƟon sample results following the excavaƟon that show remaining arsenic concentraƟons are below the established background concentraƟon of 15 mg/kg. AnalyƟcal results for the confirmaƟon samples are provided in Appendix H. Tetra Tech will include steps for establishing a background concentraƟon for arsenic in groundwater in the forthcoming Site Management Plan. The french drain will remain permanently disconnected. Recycled Earth would like to discuss an approach for future development of a new land drain at the south property when the environmental concerns for shallow groundwater are resolved. This maƩer will be addressed outside of this Report; and text revisions have been made to the Report reflecƟng this revised approach. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response oFD-3: Arsenic oFD-4: Arsenic and Oil & Grease oFD-5: Arsenic •Table 11: Four of six groundwater samples show exceedances against UDEQ Groundwater Quality Standards for the following analyte. oMW-1: Arsenic oMW-2: Arsenic oMW-3: Arsenic and TPH DRO oMS-5: Arsenic 10 Sample detecƟons are provided on Table 1 and are compared to the UTG790000 Effluent LimitaƟons and Sector N Benchmark LimitaƟons Why not test samples in Table 1 for all UTG790000 Effluent and Sector N Benchmark limitaƟons when other surface water samples (Table 5) taken on site have shown exceedances in TSS, pH, Aluminum, Copper, Iron, Zinc, and TPH DRO? The indicated water samples were analyzed for all parameters required per the approved Site CharacterizaƟon Work Plan for surface water samples. These surface water samples were not analyzed for the addiƟonal parameters in UTG790000 because this water was not considered for discharge to the MS4 (only the samples on Table 5 were considered for MS4 discharge; and the final decision was to not discharge any water to the MS4). 11 The released water flowed into Ogden City’s off-site detenƟon pond and overflowed its banks entering a storm water inlet along Midland Drive and the City’s MS4. Revise to "Recycled Earth's SE-Pond located on the Site. . ." The indicated text has been revised in the Report as requested. 12 As described in SecƟon 2.1.1, Recycled Earth constructed a temporary detenƟon pond to contain and evaporate groundwater on the southern porƟon of What is the intent with the liquids in the temporary detenƟon pond? Sample PW-1 in Table 1 shows that this liquid exceeds UTG790000 Effluent LimitaƟons for Copper The water detained in the temporary pond will be held and evaporated unƟl condiƟons allow discussion of a new land drain as described in the Response to Comment 9. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response the Site at the locaƟon shown on Figure 4. and Lead. Both PW-1 and STRENCHSW-1 exceed arsenic screening levels for Utah Groundwater Monitoring Requirements (R315-308-4) and EPA RSLs. Table 1 has been updated to include the UTG790000 effluent limitaƟon for copper. There is no requirement for lead in this general permit. 13 A conceptual site model has been developed to evaluate potenƟal connecƟons between sources and receptors as shown on Figure 11. The model idenƟfies the Beck’s SanitaƟon, Inc. discharge as the source of consƟtuents remaining in Site media (i.e., soil and groundwater) following the preliminary remedial acƟons completed as part of this work and described in this Report. Ogden City has never idenƟfied Beck SanitaƟon as the source. This secƟon should be revised to idenƟfy Recycled Earth Site as the source of the discharge. The indicated text has been revised in the Report as requested. 14 Elevated arsenic was detected in soil at french drain sample locaƟon FD-1; however, there is no risk of direct exposure because this sample was collected several feet below ground surface and has subsequently been backfilled and covered with soil from other areas of the Site determined to be clean through sample collecƟon and analysis. Wouldn't there be risk of direct exposure if the french drain was reconnected to the Site storm system per the recommendaƟon in this report? The french drain area around sample FD-1 has been excavated to remove the affected soil that originally showed an elevated arsenic concentraƟon. Three soil confirmaƟon sample results from the excavaƟon floor and sidewalls showed arsenic concentraƟons below the established background concentraƟon of 15 mg/kg, eliminaƟng the concern for soil exposure to arsenic above background levels. The results from this supplemental work have been added to the revised Report. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response 15 Further evaluaƟon of these potenƟal groundwater exposure points is unnecessary due to the small number of downgradient well users. A porƟon of the Hooper Water Improvement District (System Facility ID 29006WS005) groundwater source protecƟon zone is located less than a quarter mile downgradient to the Site. This system services a populaƟon of 19,524. Has this been considered in the Site CharacterisƟc Report? Recycled Earth has considered all known sources of water supply around Recycled Earth. The Hooper Water Improvement District’s Source ProtecƟon Zone 4 for Supply Well 4 is located approximately ¼ mile from the Recycled Earth south property. According to the UDEQ Guidelines for Groundwater Source ProtecƟon, Zone 4 is defined as an “area within a 15-year groundwater travel Ɵme to a wellhead or margin of the collecƟon area, the boundary of the aquifer(s) which supplies water to the groundwater source, or the groundwater divide, whichever is closest.” Zone 4 is the lowest threshold zone for groundwater source protecƟon. Because Recycled Earth is outside of the Zone 4 Source ProtecƟon Zone, there are no specific groundwater requirements that must be met. Furthermore, future groundwater sampling will be performed to ascertain background concentraƟons for arsenic and to establish whether TPH-DRO concentraƟons are decreasing at the south property. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response 16 There are three downgradient wells used for non-potable purposes within one mile of the Site: one is approximately 0.25 miles to the north and the remaining two are approximately one mile to the northwest. All wells are used for irrigaƟon/stock water and are not used as potable drinking water sources. Both Water Right 35-3315 and 3317 state "domesƟc" as one of the Water Uses idenƟfied at the boƩom of the water right informaƟon. Is it confirmed that domesƟc use is not occurring? See water right details from links below: hƩps://www.waterrights.utah.gov/asp_app s/wrprint/wrprint.asp?wrnum=35-3317 hƩps://www.waterrights.utah.gov/asp_app s/wrprint/wrprint.asp?wrnum=35-3315 Is a 1-mile evaluaƟon sufficient? There are many addiƟonal wells down gradient that show domesƟc use. See map here: hƩps://maps.waterrights.utah.gov/EsriMap /map.asp Water Rights 35-3315 and 3317 correspond to the two wells located one mile to the northwest. Both water claims are from 1936 and the wells were installed in the 1940s. Both wells are now located in the parking lot of a current Burger King restaurant located at 2450 S 1900 W, West Haven, Utah. The wells appear to have been paved over based on Google Street View imagery. The Water Rights well records appear to be out of date based on Recycled Earth’s supplemental research regarding these wells idenƟfied by Ogden City. The Report has been revised to reflect this addiƟonal informaƟon. 17 The Site characterizaƟon results showed that the soil and water at the Site contain no consƟtuent levels above regulatory standards, background levels, or other relevant standards except for the following observaƟons: This sentence is misleading since 82% of the on-site water and 21% of the on-site soil samples exceeded regulatory standards or background levels idenƟfied in the tables. This does not include confirmaƟon samples. It also appears that some of the tables do not show all parameters sampled as indicated in the laboratory reports. Further, it looks that there are some parameters that should have been sampled based on results of other samples. Recycled Earth interprets the City’s comment to refer to the results presentaƟon format used by Tetra Tech to indicate that most results saƟsfy applicable or relevant standards or screening criteria, “except” for certain condiƟons listed in the subsequent bullets of SecƟon 4.1. This format is well suited for the “Conclusion” secƟon because if focuses on exceeding condiƟons while acknowledging all the media samples and laboratory analytes tested that were not above the regulatory criteria (see all results in Appendix G that are non-detect and/or below regulatory criteria). RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response Furthermore, the tables in the Report show detecƟons only as is standard pracƟce to pare down the laboratory reports (Appendix G) to present a usable and interpretable summary of results. Recycled Earth does not believe changes to the language in this secƟon is required. 18 Arsenic was detected in one soil sample (FD-1) at a concentraƟon of 151 mg/kg (Table 6). This soil exceeds the established background level for arsenic (15 mg/kg); however, there is no risk of direct exposure because this sample was collected several feet below ground surface and has subsequently been backfilled and covered with soil from other areas of the Site determined to be clean through sample collecƟon and analysis. The potenƟal for arsenic migraƟon from soil to groundwater has been evaluated and may conƟnue to be evaluated by monitoring shallow groundwater at the Site. See comment [14] above. This sample was taken at the end of the french drain and Tetra Tech is recommending to reconnect the french drain and begin discharging groundwater to the Ogden storm water system. The response to this comment is the same as Responses to Comments 9 and 14; and revisions to the Report have been made to consistently describe the soil remediaƟon at Sample FD-1 with confirmaƟon sample results below the background level of 15 mg/kg. 19 Tetra Tech recommends no further remedial acƟon on or off Site based on the soil removal acƟons performed as part of this work and the results of post- remedial sampling and other sampling conducted during the Site characterizaƟon work Ogden City will follow the recommendaƟons of the DEQ related to this comment. Acknowledged. RESPONSE TO COMMENTS (RTC) FROM OGDEN CITY Site CharacterizaƟon Report for Recycled Earth South Property _6479347.2 Comment No. Referenced Text from Report Comment Tetra Tech Response 20 Tetra Tech recommends that an addiƟonal round of groundwater sampling be performed in December 2023 to re-evaluate the presence of arsenic and TPH DRO concentraƟons in the groundwater. Ogden agrees that further groundwater sampling is necessary. Acknowledged. 21 Recognizing that this is an industrial Site and the characterizaƟon consƟtuent concentraƟon levels were compared to regulatory industrial standards, Tetra Tech also recommends that a Site Management Plan (SMP) be prepared and implemented in accordance with UAC R315-101-7…… The SMP is expected to include the following elements in tandem with an environmental covenant: • Restrict land use of the Site to only industrial or commercial uses; • IdenƟfy the locaƟon of sample FD-1 that contains arsenic at a concentraƟon above background levels and the industrial RSL and require worker protecƟon soil management at depth and soil cover management; and • Restrict use of, and require worker protecƟon and management during work in, shallow groundwater. Ogden agrees that a SMP will be necessary. The restricƟon of land use should not preclude construcƟon of roadways through the property. Any SMP developed for the property must be submiƩed to and approved by Ogden City before it can be considered to be recorded. The SMP will restrict land use to commercial/industrial, without residenƟal use. The SMP is not intended to specify future land development plans and will not specifically address construcƟon of roads or other infrastructure. The DWMRC Director will publish the SMP for public comment, and Recycled Earth invites Ogden City to comment during that process or coordinate with DWMRC for prior review. 22 Table 6, Page 31. The filtered and total metals results for water samples FD-1 through FD-5 are the same. Checking laboratory report, it is the filtered sample results which are not reported on Table 6.

Introduction On behalf of Recycled Earth LLC, Tetra Tech, Inc. (Tetra Tech) has prepared this Site Characterization Completion Report (Report) for the Recycled Earth South Property located at 3025 South 1500 West in Ogden, Utah (Site) in accordance with the Site Characterization Plan (Tetra Tech 2023). The Site Characterization Plan was prepared in response to a Notice of Violation (NOV) and a Request for Voluntary Action (Request) issued to Recycled Earth. The NOV was issued by Ogden City Public Services on September 30, 2022 for a purported illicit discharge from the Site to the Ogden City Municipal Storm Sewer System (MS4). The Request was issued by the Utah Department of Environmental Quality (UDEQ), Division of Waste Management and Radiation Control (DWMRC), on August 26, 2022, and pertained to the same illicit discharge. The Request requested that Recycled Earth investigate the quantity, nature, and extent of potentially contaminated materials on the Site and potential contamination identified in connection with the purported disposal of unauthorized liquid wastes. This Report presents the findings, conclusions, and recommendations from completion of the Site characterization activities. This Report is organized as follows: Section 1.0: Introduction – Provides the Report organization and background information, including a Site description, history of releases, and regulatory actions driving this work. Section 2.0: Scope of Work – Describes preliminary remedial actions performed and the Site characterization activities completed. Section 3.0: Results – Describes final sampling results from remedial activities and Site characterization activities. Section 4.0: Conclusion – Provides a summary of results, conclusions, and recommendations based on the completed work. Section 5.0: References – Provides a list of references included in this Report. As set forth below, Tetra Tech recommends no further remedial action be undertaken based on the soil removal actions and the results of post-remedial sampling and other sampling conducted during the Site characterization work. Tetra Tech recommends that (i) an additional round of groundwater sampling be performed in December 2023 to re-evaluate arsenic and TPH DRO concentrations in the groundwater at the Site and (ii) a Site Management Plan (SMP) be implemented at the Site in accordance with the requirements of Utah Administrative Code (UAC) R315-101-7 and further described in Section 4 of this Report. SITE DESCRIPTION The Site is located at 3025 South 1500 West in Ogden, Utah as shown on Figure 1. The Site covers approximately 11 acres and includes vehicle maintenance, concrete crushing operations, and composting operations, as depicted on the Figure 2 Site Map. Concrete washout operations were historically performed near the crushing operations, but these operations are no longer performed on Site. Vehicle maintenance for Recycled Earth’s vehicles and equipment is performed in the building located on the north end of the Site, and the concrete crushing and composting operations occur on the south end of the Site. The Site was constructed in 2015 by Recycled Earth and was developed over prior agricultural lands. The Site was excavated two to four feet below the original land surface and earth berms were established around the perimeter of the Site to obscure operations from Midland Drive per Ogden City requirements. During development at the Site, shallow groundwater was encountered near the native soil surface. Groundwater levels were lowered by installing a trench filled with gravel and a perforated pipe (land or french drain) to redirect shallow groundwater to the Site Characterization Report Recycled Earth Ogden, Utah 2 November 3, 2023 _6479884.2 stormwater system to lower the groundwater table in the southern portion of the Site. The french drain connects to the southern-most inlet box that collects surface water from the operational areas on the north side of the Site, thus connecting the groundwater dewatering system to the storm water drainage system that eventually discharges to the MS4 with temporary storage in a detention basin located northwest of the Site along Midland Drive. Storm water discharges from the Site are regulated under a Utah General Industrial Storm Water Permit (UTG790000) through the MS4, which eventually discharges to the Weber River approximately two miles north of the Site. HISTORICAL RELEASES According to Recycled Earth, Recycled Earth, no significant spills or releases have occurred at the Site prior to the August 2022 illicit discharge. Recycled Earth periodically excavates soils with visible minor hydrocarbon staining from equipment leaks and properly disposes of them off Site at Intermountain Regional Landfill, which is a Class V municipal waste facility. The soil is transported along with other municipal solid waste in 40-ton haul trucks. Excavated areas are backfilled with clean gravel to the previous grade. As part of Recycled Earth’s concrete recycling operation, Recycled Earth accepted concrete washout from a variety of customers since beginning the operation. The concrete washout was received in various containers and was typically a dry or slurry form when received. The concrete washout was dumped near the base of the concrete pile located on the southern portion of the Site for subsequent crushing when fully cured. Recycled Earth stopped receiving concrete washout in August 2022 when it was discovered the Recycled Earth’s customer, Beck’s Sanitation, Inc., offloaded, without Recycled Earth’s knowledge or consent, liquid waste near the base of the concrete pile located on the southern side of the Site. Except for the purported releases identified by the City and UDEQ in their respective NOV and Request as described previously and described in the timeline below, Recycled Earth is unaware of other significant releases on or from the Site. A summary of the timeline relating to the reported August 2022 release was provided by Recycled Earth and is presented below, including the recent operational history, release history and preliminary mitigation measures: February 2022 – Recycled Earth began accepting from various customers liquids from trenchless excavation and construction projects in Ogden. One of these customers was Beck Sanitation, Inc. Beck Sanitation, Inc. that represented to Recycled Earth that it was offloading water that would be filtered through a gravel filtration system before being offloaded at the Site. Recycled Earth used this water for dust control at Recycled Earth’s concrete crushing operations. August 2022 – Recycled Earth began receiving liquids from Beck’s Sanitation, Inc. trucks at the southern end of the Site near the south end of the Site (this area is referred to as the “South Trench”). August 17, 2022 – The last load of liquid from Beck’s Sanitation, Inc. was accepted in the morning of August 17, 2022. Recycled Earth was notified mid-day about an odor coming from the MS4 conveyance system downstream of the Site. Beck’s Sanitation, Inc. informed the Weber County Health Department that it had disposed at the Site unfiltered wastewater from car wash sumps and other industrial operations, which Beck’s Sanitation, Inc. did without the knowledge or consent of Recycled Earth. (See First Amended Complaint, Recycled Earth, LLC v. Beck’s Sanitation, Inc., Case No. 220905020, 2nd Dist. Ct., Weber County, Utah (alleging Beck’s Sanitation, Inc. dumped unfiltered wastewater onto the Site). August 18, 2022 – Ogden City plugged the stormwater culvert crossing located at 2550 South Street. A Site visit was conducted by Ogden City and UDEQ to inspect the stormwater conveyance pathway from the Site. August 19, 2022 – On behalf of Recycled Earth, Clean Harbors placed silt curtains and sorbent booms at the 2550 South Street culvert and Wilson Creek crossing, and Recycled Earth placed oil absorbent booms Site Characterization Report Recycled Earth Ogden, Utah 3 November 3, 2023 _6479884.2 and pads at the Site (e.g., in catch basins and the outlet to the stormwater detention basin) and downstream at the Wilson Canal crossing. Clean Harbors also collected preliminary soil and water samples at the Site (results were included in the Site Characterization Plan). Ogden City removed the culvert plug at the 2550 South Street due to concerns for flooding. August 20, 2022 – Ogden City installed a mechanical plug to prevent water from the Site from entering the MS4, and Recycled Earth began pumping the on-Site inlet box into a temporary pond to remove potentially impacted groundwater. August 24: 2022 - Ogden City suspended Recycled Earth’s access to the MS4 for 30 days due to the detection of illicit discharge of pollutants or water containing pollutants to the MS4; and subsequently suspended access indefinitely on September 30 with the NOV, pending compliance with the City’s requirements . September 12, 2022 – Recycled Earth stopped pumping water from the inlet box. The flow to the inlet box slowed but ponding was still occurring on the Site. September 27, 2022 – DWMRC representatives inspecting the Site observed soil staining near the cement pad on the south side of the maintenance building, and Recycled Earth immediately excavated visibly affected soil and disposed of the soil off-site at Intermountain Regional Landfill along with other solid waste. Verification samples were collected by Tetra Tech from the excavation on September 27, 2022; the results showed residual hydrocarbon concentrations. This area was further excavated and resampled as part of the preliminary remedial actions as described in Sections 2.1.4 and 3.1.3. Recycled Earth retained Tetra Tech to assist in responding to the NOV and Request. REGULATORY ACTIONS Recycled Earth received a NOV from Ogden City on September 30, 2022 titled “Notice of Violation and Order of Compliance with Municipal Code 9-7D at property address: 3025 S 1500 W Ogden 84401.” According to Ogden City, the NOV was in response to complaints of odors leaving the Site and correspondence between the City and Beck’s Sanitation, Inc. and Recycled Earth. Recycled Earth was ordered in the NOV to complete the following actions: 1. Cease discharge to the City MS4 until further notice. 2. Submit an Industrial Storm Water Pollution Prevention Plan to the City. 3. Submit all records of liquid waste accepted by Recycled Earth to the City no later than 30 days after the NOV. 4. Submit all existing and future soil and water sample data obtained by Recycled Earth or their contractors to the City. 5. Collect and analyze the following soil and water samples in accordance with an approved sampling plan submitted to the City: o Minimum of five soil samples along the french drain o Minimum of two water samples from the white storage tank o All storm inlet boxes o Minimum of 10 soil and five water samples along the storm water conveyance path from Recycled Earth’s property to the Ogden City Limits 6. An environmental report assessing the situation and providing recommendations for site remediation. Site Characterization Report Recycled Earth Ogden, Utah 4 November 3, 2023 _6479884.2 These items in the NOV have been addressed previously or are addressed by this Report. Discharge to the MS4 was plugged immediately after receiving the NOV and remains plugged. Upon acceptance of these results set forth in this Report, Tetra Tech recommends that Ogden City remove the plug and allow Recycled Earth to resume at the Site storm water discharges to the MS4. On August 26, 2022, DWMRC issued Recycled Earth the Request. The Request was not a notice of violation or administrative order but was intended to provide Recycled Earth with a preliminary notice and an opportunity to take the following actions voluntarily: 1. Cease accepting solid waste materials not approved in its plan of operation, including trenchless excavation waste, liquids potentially containing greases or petroleum products, concrete washout water, car wash sump wastes, and waste asphalt. 2. Submit an updated plan of operations and investigate the quantity, nature, and extent of any potentially contaminated materials in the concrete piles on the southern campus of Recycled Earth and provide a report to the Division on this issue. 3. Prepare and submit a plan to characterize the source(s), nature, and extent of potential contamination to groundwater at the Site. These items in the Request have been addressed previously or are addressed by this Report, except for item 2, which is forthcoming and will be provided to DWMRC separately by Recycled Earth. Recycled Earth received a second notice of violation (Second NOV) from Ogden City on January 19, 2023 alleging that Recycled Earth had reinstated access to the MS4 and illegally discharged pollutants therein, following an event in which the pressure from the detained water on the Site blew out a temporary plug in one of the on-Site catch basins. The released water flowed into Recycled Earth's detention pond on the north side of the Site shown on Figure 2 and overflowed into the City’s MS4. Recycled Earth took immediate action to repair/improve the plug and immediately contacted Ogden City. The Second NOV included a penalty of $1,000. Recycled Earth appealed the Second NOV, and the appeal is currently pending before the Ogden City Mayor. Site Characterization Report Recycled Earth Ogden, Utah 5 November 3, 2023 _6479884.2 2.0 SCOPE OF WORK The scope of work performed to meet the regulatory requirements in Ogden City’s NOV and DWMRC’s Request were presented in the Site Characterization Plan, which was approved by Ogden City on January 23, 2023, and by DWMRC on January 25, 2023. The work performed included preliminary remedial actions and sampling of select areas on the Site to further characterize sources of hydrocarbons and other constituents in surface water, soil, and groundwater based on the results from preliminary sampling and analyses presented in the Site Characterization Work Plan. The following table presents a chronological timeline of activities performed at the Site; the sequence varied from the anticipated order of activities due to heavy precipitation during early 2023, which was detained over parts of the Site. Remedial Action Activity Date Detained Water Characterization January 18, 2023 Catch Basin Sampling and Cleanout February 2, June 9, 2023, and August 16, 2023 Surface Characterization February 2, 3, 9, March 10, and April 20, 2023 Subsurface Characterization May 4, 5, and 11, 2023 Excavation Near Maintenance Building May 8, 2023 French Drain Cutoff May 16, 2023 South Trench Cleanout June 29, 2023 French Drain Excavation October 19, 2023 PRELIMINARY REMEDIAL ACTIONS This section describes the preliminary remedial actions performed at specific areas to address observed and probable sources of petroleum hydrocarbon impacts at the Site. These actions were based on findings from preliminary inspections and analysis of environmental samples described in the Site Characterization Plan. The primary objective was to eliminate the sources of hydrocarbon impacts, thereby preventing potential migration to surface water or groundwater and safeguarding environmental media. 2.1.1 French Drain Cutoff The french subdrain system, running beneath the existing concrete pile from south to north, was disconnected from the stormwater drainage system. Recycled Earth cut off and sealed the outlet from the french on May 16, 2023 by excavating and cutting off the pipe south of catch basin CB-8 shown on Figure 3. Both the terminated pipe and the inlet to CB-8 were sealed with mechanical plugs to permanently disconnect the french drain from the storm water collection system. A temporary groundwater detention basin (or sink) was developed at the north end of the concrete pile concurrently with the french drain cutoff to provide an on-Site reservoir for storage and evaporation of groundwater to minimize flooding of site operations. The location of this temporary basin is shown on Figure 4. Site Characterization Report Recycled Earth Ogden, Utah 6 November 3, 2023 _6479884.2 It is anticipated by Recycled Earth that upon resolution of remaining groundwater concerns described in this report that a new land drain system may be discussed with Ogden City; and if (when) a new land drain system is installed, the temporary ground water detention basin will be filled and eliminated as a Site feature. 2.1.2 South Trench Cleanout Standing surface water in the South Trench was sampled and analyzed prior to trench cleanout for the same parameters as the site characterization surface water samples. Sample detections are provided on Table 1 and are compared to the UTG790000 Effluent Limitations and Sector N Benchmark Limitations; and all results were below the effluent limitations. Based on these results, the standing water in the South Trench was pumped into the temporary detention pond, described above in Section 2.1.1, prior to excavation. The South Trench was cleaned out via excavation on June 29, 2023 by Recycled Earth with observation and oversight provided by Tetra Tech. The excavation process was guided by visual observations and a handheld photoionization detector (PID) instrument, which was used to screen for volatile organic compounds (VOCs). The quantity of soil removed from the South Trench is estimated to be 60 cubic yards based on field dimensions. A total of seven verification samples were collected, with samples being obtained approximately every 20 feet along the trench excavation area at the locations shown on Figure 5. Based on the shape and extent of the excavation, representative samples were collected at these locations because there were no distinct bottom and sidewalls for the excavation. The samples were collected in accordance with the Standard Operating Procedures (SOPs) provided in the Site Characterization Plan. The purpose for these samples was to verify that impacted soils have been sufficiently removed to meet the applicable regulatory screening criteria and demonstrate removal of as much source material containing hydrocarbon mass as possible in the immediate area of the trench. Additionally, one soil sample was collected as a ten-point composite from the piles of excavated material to characterize the excavated soil for landfill disposal requirements. All samples were sent to Pace Analytical Laboratory (Pace) for analysis of the following parameters: VOCs to represent total petroleum hydrocarbons gasoline range organics (TPH GRO) using Method 8260B. Semi-volatile organic compounds (SVOCs) to represent total petroleum hydrocarbons diesel range organics (TPH DRO) using Method 8270C. Polycyclic aromatic hydrocarbons (PAHs) using Method 8270-SIM. The impacted soils removed from the trench were disposed of at Intermountain Regional Landfill after receiving laboratory results for the confirmation sample that showed the material was non-hazardous and acceptable to the landfill; a copy of the waste manifest is provided in Appendix A. The results for the verification samples are presented in Section 3.1. 2.1.3 Catch Basin Cleanout Prior to cleaning out the catch basins, soil samples were obtained from each catch basin. Catch basins CB-1, CB- 2, CB-3, and CB-4 were sampled on February 2, 2023. Notably, sample locations CB-5, CB-6, and CB-7 identified in the Site Characterization Plan were empty and could not be sampled. Catch basins CB-8 and CB-9 were in the flooded area of the Site and were therefore sampled later on June 9, 2023. The samples were collected as grab samples in accordance with the applicable SOPs provided in the Site Characterization Plan. The samples were sent to Pace for analysis of the following parameters: PPL Metals by Methods 6010B and 7471A VOCs to represent TPH GRO by Method 8260B SVOCs to represent TPH DRO by Methods 8270C Site Characterization Report Recycled Earth Ogden, Utah 7 November 3, 2023 _6479884.2 PAHs by Method 8270-SIM The locations of the catch basins are shown and numbered for identification purposes on Figure 3. The results for the catch basin samples are presented in Section 3.1. The on-site catch basins containing sediment were cleaned out by Recycled Earth at various times during the site characterization activities with final cleanout and inspection on August 16, 2023, with verification by Tetra Tech. The material from the catch basins was disposed of at Intermountain Regional Landfill after receiving sample results confirming that the sediment in the catch basins is non-hazardous. Copies of waste manifests are provided in Appendix A. The catch basin sediment traps were hand shoveled and pumped out to remove potentially impacted media. The quantity of solids removed from the catch basins was relatively small and these materials were disposed of with other solid wastes from the Site at the Intermountain Regional Landfill. 2.1.4 Excavation Near Maintenance Building The excavation near the cement pad on the south side of the maintenance building on the Site was expanded to remove additional residual petroleum hydrocarbon impacts. After the additional excavation was completed, five confirmation samples were collected on May 8, 2023. Three samples were collected in the footprint of the excavation, four on the sidewalls, and one on the floor at the locations shown on Figure 6. The samples were obtained as grab samples in accordance with the relevant SOPs provided in the Site Characterization Plan. The samples were sent to Pace for analysis of the following parameters: PPL Metals by Methods 6010B and 7471A VOCs to represent TPH GRO by Method 8260B SVOCs to represent TPH DRO by Methods 8270C PAHs by Method 8270-SIM The earthwork associated with this remedial action was performed by Recycled Earth with observation and oversight provided by Tetra Tech. It is estimated that six cubic yards of soil were excavated to complete this remedial action. The excavated soil was disposed of at the Intermountain Regional Landfill and a copy of the waste manifest is provided in Appendix A. DETAINED WATER CHARACTERIZATION AND PERMITTING The plug installed at Recycled Earth’s MS4 outlet led to a substantial volume of detained water held on the Site. The detained water initially flooded the center of the Site where concrete crushing activities were previously performed, as shown on Figure 4. During the highest water level, it was estimated that approximately 600,000 gallons of water were detained in this area. Excess water was attributed to unusually high precipitation early in 2023 and groundwater discharge from the french drain outlet (i.e., catch basin CB-8 shown on Figure 3). Groundwater discharge was higher than normal during the spring of 2023 due to record snowmelt and related runoff from the nearby Wasatch Mountains. On January 13, 2023 the pressure from the detained water on the Site blew out the temporary plug installed over catch basin CB-9 (Figure 4). The released water flowed into Recycled Earth's detention pond located on the Site and overflowed its banks entering a storm water inlet along Midland Drive and the City’s MS4. Recycled Earth took immediate action and installed an earthen plug over the catch basin to isolate the detained on-Site water from the detention basin. The plug was constructed by packing a plastic tarp filled with road base material secured with zip ties into the 12-inch pipe on the north side of the catch basin. A geosynthetic fabric was then placed under the catch basin grate and an additional plastic tarp was placed over the grate. Approximately 200 tons of road base material was placed on top of the tarp until the plug extended one to two feet above the ponded area. The earthen plug was later replaced by a mechanical plug that completely sealed off the french drain Site Characterization Report Recycled Earth Ogden, Utah 8 November 3, 2023 _6479884.2 connection to the storm water system as described in Section 2.1.1. Recycled Earth and Tetra Tech immediately contacted Ogden city about the temporary plug failure and its swift action to re-plug the detained water. Tetra Tech collected four initial water samples from the detained water on January 18, 2023 from the locations shown on Figure 4. The samples were analyzed for the following parameters: pH Chemical oxygen demand (COD) Total suspended solids (TSS) Total dissolved solids (TDS) Total recoverable lead Oil and grease Benzene, toluene, ethylene, and xylene (BTEX) Methyl tert-butyl ether (MTBE) Naphthalene Total toxic organics (TTO) TPH gasoline range organics (GRO) TPH Diesel range organics (DRO) Select metals, including: o Total recoverable aluminum o Arsenic o Barium o Beryllium o Total recoverable cadmium o Total recoverable chromium o Total recoverable copper o Total recoverable iron o Total recoverable lead o Mercury o Selenium o Total recoverable silver o Total recoverable zinc The results for these samples are presented in Section 3.2. Recycled Earth initially planned to treat and discharge the detained water under a General Permit for Treated Groundwater and Surface Water (Permit Number UTG790000); however, it was later decided to continue to hold the water on Site based on decreased precipitation and increased evaporation during the summer months, which significantly reduced the volume of water held on Site. Also, Recycled Earth’s attempts to retain a water treatment contractor proved to be cost- prohibitive. As described in Section 2.1.1, Recycled Earth constructed a temporary detention pond to contain and evaporate groundwater on the southern portion of the Site at the location shown on Figure 4. Tetra Tech collected a water sample from the temporary detention pond on July 14, 2023, in order to characterize the remaining water held on- Site. The results for this detained groundwater sample are presented in Section 3.2. SURFACE MEDIA CHARACTERIZATION This section presents the scope of work for sampling and analysis required by DWMRC and Ogden City. This work included sampling and analysis of surface soils and water at the locations shown on Figures 7 through 9. A Site Characterization Report Recycled Earth Ogden, Utah 9 November 3, 2023 _6479884.2 brief description of the investigation methods is provided below, and complete SOPs developed by Tetra Tech for these activities are in the Site Characterization Plan. Per the NOV from Ogden City, the following samples were collected on- and off-Site: 1. Five water and five soil samples were collected at generally equal distances along the extent of the french drain on April 20, 2023 (Figure 7). The samples were collected by excavating to the water table at each location and collecting samples from the open excavations. Soil samples were collected just above the soil-groundwater interface. The french drain invert depth is approximately five feet below ground surface and is below the water table. 2. Seven soil samples were collected from the locations shown on Figure 8: a. SS-1, SS-2, SS-3 and SS-4 samples were collected from below the broken concrete pile on the southern end of the Site on April 20, 2023. Areas of the broken concrete pile required movement to allow for soil sampling below the concrete. b. Sample, SS-5, was collected on the east side of the concrete pad south of the maintenance building on February 2, 2023. c. Samples SS-6 and SS-7 were collected from the stormwater detention basin on February 2, 2023. 3. Three concrete samples were collected from the broken concrete materials on the southern side of the Site; and one processed (crushed) concrete sample was collected from one of the piles in the center of the Site on March 10, 2023 (Figure 8). Samples were collected from one to two foot depth below the surface of the pile and were crushed to a fine powder using a sledgehammer prior to submittal to the laboratory for analysis. 4. Five water samples and six soil samples were collected along the stormwater conveyance flow path from the Site to the Ogden City Limits on February 3 and 9, 2023 (Figure 9). Each water sample had a corresponding soil sample from the same location except for SW-4, which was in a deep stormwater catch basin that could not be entered for safety reasons. Per direction from Ogden City, sample SS-12 was moved to a location along the Wilson Canal northeast of SW-5 and SS-13. All samples were collected in accordance with the SOPs provided in the Site Characterization Plan. The samples were sent to Pace for analysis of the following parameters: Priority pollutant list (PPL) Metals by Methods 6010B and 7471A Chromium (VI) by Methods 3060A/7199 and 3500 CR C-2011 Total Solids by (water samples only) Method SM2540 D Oil and Grease (water samples only) by Method 1664A VOCs to represent GRO by Method 8260B SVOCs to represent DRO by Methods 8270C PAHs by Method 8270-SIM Total petroleum hydrocarbons oil range organics (TPH ORO) using Method 8015 Polychlorinated Biphenyls (PCB) Congeners by Method 8082 Additionally, three confirmation samples were collected from an excavation near the french drain inlet. The additional excavation was performed in response to the french drain soil sample results for this location, as described in Section 3.3.1. The confirmation samples were analyzed by Pace for total arsenic. SUBSURFACE CHARACTERIZATION This section describes groundwater monitoring well locations, installation procedures, and groundwater monitoring requirements. Site Characterization Report Recycled Earth Ogden, Utah 10 November 3, 2023 _6479884.2 2.4.1 Subsurface Soil Sampling Six monitoring wells were installed on May 4, 2023 at the locations shown on Figure 10 using direct push drilling techniques operated by ET. Technologies with observation and oversight provided by Tetra Tech and in accordance with the revised SOP provided in Appendix B. The revision to the SOP included using direct push methods instead of hollow-stem-auger drilling and such method was approved by DWMRC on April 28, 2023. Blue Stakes was notified prior to the well installations and a private utility locator came on Site and used ground penetrating radar to mark the target well locations. The boreholes were performed sequentially with each boreholes being two inches in diameter and extending to five feet below the water table. The soil lithologies were logged during drilling and the dates and times of soil sample collection, along with the corresponding Quality Control samples, are provided in the Soil Sample Logs provided in Appendix C. One subsurface soil sample was collected from each borehole for laboratory analysis. The samples were collected as grab samples using the collection methods described in the SOPs provided in the Site Characterization Plan. Samples were collected from areas of visibly impacted soils, soils showing detection of volatile organic vapors with the PID, or from a depth immediately above the water table if observations of potential impacts were not observed. The samples were shipped to Pace for analysis of the following parameters: PPL Metals by Methods 6010B and 7471A Chromium (VI) by Methods 3060A/7199 and 3500 CR C-2011 VOCs to represent GRO by Method 8260B SVOCs to represent DRO by Methods 8270C PAHs by Method 8270-SIM TPH ORO by Method 8015 PCB Congeners by Method 8082 All sampling and excavation equipment were decontaminated between locations using potable water, and the decontamination liquids and soil cuttings were removed from the Site for proper disposal. The soil borings were completed as shallow groundwater monitoring wells in accordance with the SOPs provided in the Site Characterization Plan. Protective well casings (vaults) were complete for the wells on May 5, 2023. 2.4.2 Groundwater Sampling The monitoring wells were developed prior to sampling on May 8, 2023 using development techniques described in the revised SOP 011 provided in Appendix B. The procedures and results of the well development process for each monitoring well are presented in Appendix C. Groundwater samples were collected on May 11, 2023 using the procedures described in the SOPs provided in the Site Characterization Plan. Samples were collected after a minimum of three well volumes had been purged from the well and field parameters (temperature, pH, specific conductivity, dissolved oxygen, and oxidation- reduction potential) were within 10% of prior readings. Groundwater samples were analyzed for constituents listed in UAC R315-308-4 as directed by the DWMRC: Inorganic Constituents: o ammonia (as N) - 350.1 o carbonate/bicarbonate - 2320 B-2011 o calcium - 6010 o COD - 410.4 o chloride – 9056 o iron - 6010 o magnesium - 6010 Site Characterization Report Recycled Earth Ogden, Utah 11 November 3, 2023 _6479884.2 o manganese - 6010 o nitrate (as N) - 9056 o pH - 9045 o potassium - 6010 o sodium - 6010 o sulfate - 9056 o TDS - 2540 C-2011 o total organic carbon (TOC) - 9060A PPL Metals by Methods 6010B and 7471A VOCs by Method 8260B SVOCs by Method 8270C In addition, TPH GRO (Method 8060) and TPH DRO (Method 8070) concentrations were obtained through the VOC and SVOC analyses, given the nature of past releases and the preliminary laboratory results. Groundwater elevations were surveyed for each well on May 17, 2023. Interpolated groundwater contours and the interpreted direction of groundwater flow are presented on Figure 10. QUALITY ASSURANCE Duplicate samples were collected at a rate of one per every ten samples and Matrix Spike/Matrix Spike Duplicate (MS/MSD) samples were collected at a rate of one per ten samples. The results from quality assurance sampling and analysis are presented in Section 3.5. The person collecting the samples was responsible for sample custody from the time of sample collection to receipt by a laboratory or until samples were shipped. A sample is considered under custody if one of the following conditions applies: The sample is in a person’s possession. The sample is in that person’s view after being in his or her possession. The sample was in that person’s possession and then placed in a secured location. The sample is in a designated secure area. A Chain-of-Custody Record with its assigned sample numbers accompanied all samples to the laboratory. When samples were shipped, custody seals were attached to each cooler to ensure that tampering with the samples did not occur in transit, and the shipment air bill became part of the Chain-of-Custody documentation. Site Characterization Report Recycled Earth Ogden, Utah 12 November 3, 2023 _6479884.2 3.0 RESULTS This section presents the analytical results for confirmation samples and Site characterization work and compares them to the regulatory limits, screening levels and/or background values as applicable and presented in the approved Site Characterization Plan. This section also presents a conceptual site model developed based on the site characterization findings. Daily field forms describing field activities and are included in Appendix D. Representative photos capturing project work are provided as a photo log in Appendix E. Soil sampling logs are provided in Appendix F and full laboratory analytical reports organized in chronological order by sample collection date are provided in Appendix G. PRELIMINARY REMEDIAL ACTION VERIFICATION RESULTS 3.1.1 South Trench Excavation The South Trench soil verification sample locations are shown on Figure 5, and the corresponding, detected results are presented on Table 2. All detections for the verification samples were below the U.S. Environmental Protection Agency (EPA) Industrial Regional Soil Screening Levels (RSLs), and the South Trench excavation is complete having achieved the target remediation levels. 3.1.2 Catch Basin Sampling Soil detections for the catch basin sediment samples are provided on Table 3. All samples exceeded the EPA RSLs for arsenic, which is set at 3 mg/kg. The highest level detected was 53 mg/kg in sample CB-2. Sample CB-4 exceeded the EPA RSL for TPH DRO at a concentration of 3,600 mg/kg. This sample was located near the maintenance building. All impacted sediment was removed from the catch basins, was properly landfilled off Site, and does not pose a risk to the environment or future surface water discharged to the MS4. 3.1.3 Excavation Near Maintenance Building Confirmation soil sample detections are provided on Table 4. All five confirmation samples exceeded the EPA RSL for arsenic; all other detections were below the EPA RSLs. The arsenic concentrations are all below the background threshold value (BTV) of 15 mg/kg established through correspondence between Recycled Earth and DWMRC dated August 9, 2023 confirming that this “surrogate” BTV was obtained from the Ogden Business Exchange Voluntary Cleanup Program documents, as described in the agency-approved Site Characterization Report (Section 2.3.2), and as such this value is an acceptable BTV per the Technical Guide for Risk Assessment. DETAINED WATER CHARACTERIZATION Detections for the ponded water samples are provided on Table 5. The results were compared to the UTG790000 Effluent Limitations and Sector N Benchmark Limitation. Note that the benchmark limitations for copper, lead, and zinc are based on the hardness of the Weber River. Tetra Tech obtained hardness data from the UDEQ, Division of Water Quality. Hardness was calculated from Ca and Mg as CaCO3 equivalent and was equal to 360 mg/L. All detections were below the effluent limitations with the following exceptions: Site-North exceeded the Sector N Benchmark Limitation for TSS and the UTG790000 limitation for zinc Site-North, SE-Pond, and Outfall #1 exceeded the UTG790000 effluent limitations for pH Site-South and Site-North exceeded the Sector N Benchmark Limitations for aluminum and iron All samples exceeded the effluent limitations for copper Site Characterization Report Recycled Earth Ogden, Utah 13 November 3, 2023 _6479884.2 Site-North and Outfall #1 exceeded the UTG790000 for TPH DRO These results indicated that Recycled Earth could not discharge the detained water to the MS4 without prior treatment. The water was detained at the Site until weather conditions changed and the water levels were reduced. Sample detections for the temporary groundwater detention pond are provided on Table 1 for comparison to the results for the South Trench water sample. All results were below the UTG790000 Effluent Limitations and Sector N Benchmark Limitations. SURFACE MEDIA CHARACTERIZATION RESULTS This section describes the results of the surface characterization samples collected on and off Site in accordance with the Site Characterization Plan. 3.3.1 French Drain Sample Results The french drain sample detections are presented on Table 6. Arsenic concentrations were above the EPA RSLs for all soil samples but were below the established background concentration of 15 mg/kg except for sample FD-1 located near the former french drain inlet that had an arsenic concentration of 151 mg/kg. Based on the elevated arsenic detected at FD-1 and direction from the DWMRC that remediation of this area would be required for site closure, supplemental soil excavation was performed at this location on October 18, 2023. Recycled Earth informed the DWMRC and Ogden City of the planned excavation activities via email correspondence issued by Tetra Tech dated October 13, 2023. Approximately 8 cubic yards of material was removed and disposed of at Intermountain Regional Landfill; a copy of the waste manifest is provided in Appendix A. Three confirmation soil samples were collected from the excavation floor and sidewalls and were analyzed for total arsenic. All three samples were below the background concentration of 15 mg/kg for arsenic. Confirmation sample locations, analytical results, and representative photographs of the excavation at this location are provided in Appendix H. All groundwater results were below the UDEQ Groundwater Quality Standards except for arsenic. As directed by the DWMRC, the Division’s Technical Guide for Risk Assessments (Guide) was used to assess risk associated with TPH. The TPH risk was evaluated by assessing individual chemical constituents identified in the Guide rather than relying on TPH fraction data due to the limitations of TPH measurement techniques which provide no specific information about individual detected hydrocarbons. EPA Tap Water RSLs were compared to groundwater results for indicator compounds associated with common TPH mixtures. All french drain groundwater results were below the EPA Tap Water levels for the indicator compounds except for arsenic. 3.3.2 Soil Sample Results Surface soil sample detections are provided on Table 7. All detections were below the EPA RSLs except for the following samples for the indicated parameters: All soil samples exceeded the EPA RSL for arsenic; however, only sample SS-13 at 87 mg/kg was above the established background concentration of 15 mg/kg. Sample SS-13 exceeded the EPA RSL for silver and TPH-DRO. The detection of elevated arsenic at sample SS-13 could be related to naturally occurring high arsenic although it is significantly higher than the background level; and the elevated arsenic and TPH-DRO could come from other Site Characterization Report Recycled Earth Ogden, Utah 14 November 3, 2023 _6479884.2 industrial operations along the channel between Recycled Earth and the Wilson Canal crossing where this sample was collected. Other soil samples collected during this investigation from the channel between Recycled Earth and the Wilson Canal crossing did not show arsenic or TPH-DRO above the background or RSL values, respectively indicating that there are sections of channel between these locations that are not impacted above regulatory or background levels. Furthermore, Gas Chromatogram (GC) and Gas Chromatogram/Mass Spectrometry (GC/MS) charts were obtained from the laboratory and used by Tetra Tech to compare on- and off-Site GC and GC/MS fingerprints for petroleum hydrocarbon compounds. Based on the analysis of these data, the major naturally occurring peaks present in off-Site samples were not identified in on-Site samples and major naturally occurring peaks in on-Site samples were not identified in off-Site samples. Importantly, the highest peaks shown on the chromatograms are internal standards and surrogates used by the laboratory for calibration purposes, and they do not reflect actual constituents in the samples. Peaks for ethanol, isopropyl alcohol, and acetone were observed in several samples; however, these are common laboratory contaminants and are not associated with the purported release at the Site. These data support that the petroleum hydrocarbons identified downstream and off Site do not come from the same source as the hydrocarbons identified on Site. Tetra Tech’s analysis of the GC and GC/MS charts is included in Appendix I. 3.3.3 Surface Water Sample Results Surface water sample detections are presented on Table 8. All surface water sample detections collected for the Site Characterization were below the regulatory comparison criteria except for Sample SW-1 that exceeded the UTG790000 Effluent Limitations for copper, zinc, and diesel range organics. This location is approximately 0.25 miles downgradient from the Site; therefore, it is unknown whether the source of these elevated results comes from other industrial businesses and/or the historical railroad adjacent to the channel in this area. These constituents were not elevated elsewhere along the stormwater conveyance system in surface water. Gas Chromatogram (GC) and Gas Chromatogram/Mass Spectrometry (GC/MS) charts were also reviewed for the water samples to compare on- and off-Site GC and GC/MS fingerprints for the petroleum hydrocarbon compounds detected at Sample SW-1. Based on the analysis of these data, the petroleum hydrocarbons identified downstream and off Site are not the same as those detected on Site and do not come from the same source. Tetra Tech’s analysis of the GC and GC/MS charts is included in Appendix I. 3.3.4 Concrete Sample Results The concrete sample detections are presented on Table 9. All detections were below the EPA RSLs and the Toxicity Characteristic Leaching Procedure (TCLP) Rule of 20 except for sample CS-1, which exceeded the EPA RSL with a concentration of 3.8 mg/kg arsenic, which is below the established background concentration of 15 mg/kg and not considered to pose a risk to the environment or potential users of the concrete product. In accordance with the correspondence received by Recycled Earth from DWMRC dated April 5, 2023, and based on the results from this evaluation, Recycled Earth has resumed production and sale of crushed concrete products. SUBSURFACE CHARACTERIZATION RESULTS This section describes results for the subsurface characterization samples collected on Site. The locations of the soil borings and monitoring wells are shown on Figure 10, and corresponding Borehole Logs detailing soil sample depths, depth to water, lithology, PID readings, and well construction schematics are provided in Appendix C. Site Characterization Report Recycled Earth Ogden, Utah 15 November 3, 2023 _6479884.2 3.4.1 Subsurface Soil Sample Results During advancement of the soil borings, only the subsurface soils at location MW-6 showed a PID reading above the background level, indicating a detection of volatile organic vapors at 1.2 parts per million (PPM) using the field instrument. The soil sample detections from each soil boring are presented on Table 10. All sample results were below EPA RSLs except for arsenic, but all results were below the established background concentration of 15 mg/kg. 3.4.2 Groundwater Sample Results The groundwater sample detections for each monitoring well are presented on Table 11, and corresponding groundwater sampling logs are provided in Appendix C. All detections were below the Utah Groundwater Protection Standard (UGPS) except for arsenic at wells MW-1, MW-2, MW-3, and MW-5 for both filtered and unfiltered samples. Notably, arsenic was detected in MW-1, which is upgradient from the historical release area (i.e., the South Trench) and serves as a background well. The detections of arsenic in shallow groundwater are likely due to elevated arsenic occurring naturally in the regional soils. Sample MW-3 exhibited concentrations of TPH DRO at 1.8 mg/L. As directed by the DWMRC, the Division’s Technical Guide for Risk Assessments (Guide) was used to assess risk associated with TPH. The TPH risk was evaluated by assessing individual chemical constituents identified in the Guide rather than relying on TPH fraction data due to the limitations of TPH measurement techniques which provide no specific information about individual detected hydrocarbons. EPA Tap Water RSLs were compared to groundwater results for indicator compounds associated with common TPH mixtures. All groundwater results were below the EPA Tap Water levels for the indicator compounds except for arsenic and manganese. The presence of TPH DRO at well MW-3 is believed to be related to the detention and ponding of surface water on the west side of the property prior to installation of the well. The surface water in this area was also observed to contain TPH DRO concentrations. QUALITY ASSURANCE Quality Assurance samples, sample locations, and sample times are listed in the sample logs in Appendix F. Chain of Custody documents included with the full laboratory reports are provided in Appendix G. Duplicate sample results and the relative percent difference (RPD) between duplicate and parent samples are presented on Table 12. The RPD was not calculated for sample pairs where one or more of the samples were non-detect. The RPD ranged from 0 to 157% and 85% of results had an RPD less than 35%. MS and MSDS sample results are provided in the laboratory reports provided in Appendix G. Based on the quality assurance sample results and evaluation of these data as described herein, the results obtained during these activities are considered valid for their purposes of characterizing the Site. CONCEPTUAL SITE MODEL Due to the limited number of samples showing elevated levels of constituents above EPA RSLs (i.e., arsenic and TPH DRO), established background concentrations, or other regulatory criteria, Tetra Tech does not recommend performing a quantitative risk assessment to evaluate potential risks associated with the Site. However, development of a conceptual site model is relevant for evaluation of the results in the context of potential constituent migration and exposures to human and/or ecological receptors. A conceptual site model has been developed to evaluate potential connections between sources and receptors as shown on Figure 11. The model identifies the 2022 discharges to the Recycled Earth Site as the source of Site Characterization Report Recycled Earth Ogden, Utah 16 November 3, 2023 _6479884.2 constituents remaining in Site media (i.e., soil and groundwater) following the preliminary remedial actions completed as part of this work and described in this Report. Potential soil exposure points and exposure routes are mitigated as described below for the few remaining detections of constituents above regulatory levels in soils: Elevated arsenic and TPH-DRO detected in three catch basins do not pose a risk to human and/or ecological receptors because the catch basins are cement lined and were cleaned out to remove the sediment that contained these parameters. Elevated arsenic was originally detected in one soil sample from french drain sample location FD-1; however, remediation was performed at the direction of DWMRC, soil from this location was removed and disposed of off-Site, and confirmation samples from the excavation floor and sidewalls were below the established background concentration of 15 mg/kg for arsenic. Based on these results, there is no remaining exposure pathway for subsurface soils. The potential for arsenic to migrate from the soil at this location into groundwater can be directly assessed by monitoring site groundwater, as has been done for this Site characterization. Low detections of arsenic were detected in all groundwater samples at the Site and elevated TPH-DRO was detected at one well (MW-3). Potential exposure points, exposure routes and receptors to groundwater impacts are presented on Figure 11. Further evaluation of these potential groundwater exposure points is unnecessary due to the small number of downgradient well users. Tetra Tech conducted a review of the interactive Utah Division of Water Rights (DWR) well permit website to identify wells downgradient from the Site. There are no municipal water supply wells within one mile downgradient from the Site A 1-mile radius is considered sufficient for evaluation for shallow groundwater impacts, as this water is not utilized or suitable for water supply use due to the presence of high dissolved solids concentrations typical of the regional shallow aquifer along the Wasatch Front. The Utah Division of Water Rights identifies three downgradient wells potentially used for non-potable purposes within one mile of the Site. One well is located approximately 0.25 miles to the north (Water Right 35-4501), and the remaining two wells are approximately one mile to the northwest (Water Rights 35-3315 and 35-3317) of the Site. The claim for Water Right 35-4501 is from 1970 and was for irrigation/stock water, and not potable drinking water; no public information was available on the depth of the well. The well currently is located in the parking lot of Lansing Building Products and appears to have been paved over based on aerial imagery. The claims for Water Rights 33-3315 and 35-3317 are from 1936. Both wells were installed in 1940 and were drilled to 302 feet below ground surface. The wells were used for irrigation, stock watering and domestic use, according to the well records with the Division of Water Rights. The locations of these wells are in the parking lot of a current Burger King restaurant and appear to have been paved over based on aerial imagery and Google Street View imagery. Based on the records for Water Rights 35-3315 and 35-3317 and their location in a paved parking lot, it is highly unlikely that these wells currently exist and they are certainly not used for domestic purposes. Based on this review, the arsenic and TPH-DRO concentrations that slightly exceed the regulatory levels in groundwater will not pose a risk to groundwater users near the Site. However, additional groundwater monitoring is recommended in Section 4.2 to observe Site groundwater conditions. Site Characterization Report Recycled Earth Ogden, Utah 17 November 3, 2023 _6479884.2 4.0 CONCLUSIONS AND RECOMMENDATIONS The following subsections present the summary of findings and recommendations for the Site. SUMMARY OF FINDINGS The Site characterization results showed that the soil and water at the Site contain no constituent levels above regulatory standards, background levels, or other relevant standards except for the following observations: Catch basin samples CB-2 and CB-8 exceeded the established background concentration for arsenic (15 mg/kg) with concentrations of 53 and 18 mg/kg, respectively. Sample CB-4 exceeded the EPA RSL for total petroleum hydrocarbon diesel range organics (TPH-DRO) with a concentration of 946 mg/kg (Table 3). The catch basins were cleaned out by Recycled Earth with oversite by Tetra Tech, and the materials were disposed of off Site at a commercial solid waste landfill. No further action is required for the catch basins. Arsenic was originally detected in one soil sample (FD-1) at a concentration of 151 mg/kg (Table 6). The soil from this location was subsequently removed for off-Site disposal, and confirmation samples from the excavation floor and sidewalls showed remaining soil to be below the established background concentration of 15 mg/kg for arsenic. No further action is required for this location. Arsenic was detected in all groundwater samples collected along the french drain and from four of the six monitoring wells with concentrations ranging from 0.015 to 0.63 mg/L (Tables 6 and 11). These levels exceed the UGPS for arsenic set at 0.01 mg/L. Importantly, arsenic was detected in the background well at the Site (MW-1) at a concentration of 0.018 mg/L, suggesting that arsenic detections above the UGPS in groundwater are naturally occurring. No remedial action is recommended for this location, but additional groundwater monitoring is recommended as described in the section below. Well MW-3 showed an elevated level of TPH-DRO in groundwater at 1.8 mg/L (Table 11). All groundwater results were below the EPA Tap Water levels for the indicator compounds for TPH except for arsenic and manganese. Tetra Tech recommends future groundwater sampling to monitor TPH-DRO concentrations at this location, as described in the section below. RECOMMENDATIONS Tetra Tech recommends no further remedial action on or off Site based on the soil removal actions performed as part of this work and the results of post-remedial sampling and other sampling conducted during the Site characterization work. Tetra Tech recommends that an additional round of groundwater sampling be performed in December 2023 to re-evaluate the presence of arsenic and TPH DRO concentrations in the groundwater. Recognizing that this is an industrial site and the characterization constituent concentration levels were compared to regulatory industrial standards, Tetra Tech also recommends that a Site Management Plan (SMP) be prepared and implemented in accordance with UAC R315-101-7. The SMP will specify controls and conditions to manage potential risks to human health and the environment to the acceptable levels considered for the current and reasonably anticipated future industrial land use. The SMP is expected to include the following elements in tandem with an environmental covenant: Restrict land use of the Site to only industrial or commercial uses; Present a plan for future groundwater monitoring and analysis, including further evaluation to determine whether arsenic and manganese in groundwater at the levels detected is a background condition or related to Site impacts. Site Characterization Report Recycled Earth Ogden, Utah 18 November 3, 2023 _6479884.2 Restrict use of, and require worker protection and management during work in, shallow groundwater until the TPH-DRO and arsenic issues are resolved to satisfy regulatory acceptable criteria. The SMP will be submitted to DWMRC within 60 days of agency concurrence with this Report in accordance with UAC R315-101-7. Based on the results presented herein and upon concurrence by Ogden City, Recycled Earth will coordinate with the City to reconnect the Site storm water conveyance systems to the MS4, and corresponding storm water management will be performed under the existing Industrial Storm Water General Permit and Site-specific Storm Water Pollution Prevention Plan.

Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 1 of 12 Groundwater monitoring well installation 1. Purpose The purpose of this Standard Operating Procedure (SOP) is to delineate the quality control measures required to ensure the accurate installation of groundwater monitoring wells. The term monitoring well is used to denote any environmental sampling well. 2. Procedure 2.1 FIELD PREPARATION Notify client, property owner prior to sampling date in case there is any requirement to reach property. 2.1.1 Forms Gather proper field forms necessary for field sampling such as: Daily Report Sheets Field Service Request Tailgate Health and Safety Excavation Permits Utility clearances Borehole logging form Well completion forms Appropriate work plan 2.1.2 Drilling Equipment Appropriately sized drill rig adequately equipped with sampling equipment, bits, drill stem, etc. Steam cleaner and water obtained from an approved source for decontaminating drilling equipment TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 2 of 12 Water level indicator LEL-oxygen monitor Steel drums for investigation derived waste (drill cuttings, contaminated PPE, decon solution) (if necessary) Source of approved water Heavy plastic sheeting Decontamination area 2.1.3 Well installation materials The specifications for the following materials are included in the well construction: Well screen Riser pipe Plugs/caps Filter pack Bentonite Portland cement Steel protective casing Submersible pump Surge block Concrete Decontamination equipment including: Deionized or distilled water Alconox graduated cylinders paper towel 2.1.4 Personal Equipment Appropriate PPE (see HASP) Munsell color chart Hand lens Folding rule First aid kit Fire extinguisher 2.2 WELL DRILLING PROCEDURE 2.2.1 Rationale Sound groundwater sample integrity is dependent primarily on strict adherence to properly conceived monitor well construction and development procedures. In addition, it is equally important that boreholes (i.e., soil borings, wells, and piezometers) be abandoned properly, when necessary, to preclude the possibility of cross-contamination of water-bearing zones. To ensure that these goals are met, the following monitoring well drilling, and completion procedures will be utilized. 2.2.2 Preliminary procedures Never assume the rig will arrive on-site completely decontaminated from the previous job. Always inspect it. Road dust can have elevated levels of organics and inorganics attached to it. It is always a good idea to have the drillers lay out all the tools from their side tool panels and wash both the tools and the storage compartments. Between holes and on-site locations, ensure that dirty tools are decontaminated before being returned to these compartments The following standard field procedures should be followed at each borehole location: Check the location and number of the drilling location against a map and against the flag or stake. A good rule of thumb is to measure twice, and drill once. TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 3 of 12 TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 4 of 12 Make sure you have a utility clearance for that location. Back the rig into position so you do not have to drive over the finished hole. Set up the work area (and sample holding area) to be upwind of the rig exhaust. This may require the work area to be moved several times during the day. Check the condition of the driller’s downhole measuring device. Often these devices are missing several inches, tenths of inches, or feet, and, if used, will result in contradictory hole and well completion information. Remove any electrical tape or materials from any devices that, if lost downhole, could result in possible contamination of groundwater. Ensure that the measuring device is decontaminated each time it is used. Drilling is a team effort that includes personnel and the driller. Arrange with the driller before activities begin to keep you informed of what he/she sees or believes is happening downhole. For example, the driller can often tell you when the soil is getting harder or softer, or when he/she is losing or gaining fluids (the hole is making water). These comments often may be related later to lithologic and hydro stratigraphic changes and, therefore, may verify logs. 2.2.3 Direct Push Technology Direct push methods use up to 40,000 pounds of hydraulic force to push a steel instrumented cone or a sampling device into the ground. No material comes to the surface unless soil or groundwater samples are being collected. 2.2.3.1 Advantages This method is generally cleaner than other drilling techniques that require a water supply and may result in the need to containerize drilling fluids (e.g., muds) as well as cuttings. No material comes to the surface unless soil or groundwater samples are being collected. Because no drilling muds introduced to the hole, soil and groundwater samples are considered more accurate and representative. Sample moisture content is more likely to be representative of the formation. Small-diameter monitoring wells can be installed quickly and efficiently. 2.2.4.2 Limitations Limited in depth of penetration to approximately 100 feet depending on the materials encountered and the size of the drill rig. Can smear a layer of fine-grained soil on the side of borehole that may prevent groundwater from entering. The finer the matrix, the greater the chance for smearing the side of the hole. 2.2.3.3 Procedures Once the rig is in place, ensure that it is level by insisting that the driller use a carpenter’s level on each rig. Unaided visual assessment of plumbness is not acceptable. Using the direct push drill rig, advance a carbon steel core sampler containing a 2 or 3- foot clear acetate sample tube to the desired depth into the soil. This is referred to as a sampling interval. Carefully watch the progression of the core sampler while recording blow counts and note irregularities in the penetration rate. Upon removal of the sampler from the borehole, the acetate sample tube will be removed and the ends will be capped to prevent volatilization from the sample. Sample tubes will be marked with the depth interval and the sample orientation. Place acetate sample tubes on clean polyethylene sheeting for inspection/sampling. Each sample tube will be inspected for the presence of groundwater. The tube will be cut lengthwise using a decontaminated closed blade knife, and the soil will be logged. These steps will be repeated until the desired boring depth is reached. Record observations of: - Sampler penetration rates. - Characteristics of sample (i.e., moisture content, color, and texture), including changes in the nature (behavior) of the sample. For example, if the soil begins to form balls or rope, moisture in the soil has probably increased at that depth. - Gravel, boulders, and competent bedrock will make the rig bounce, or vibrate. - Remember that the samples appear at the surface after a time lag, and that this lag increases with the depth of the hole; therefore, it is not possible to correlate cuttings with the exact depth being drilled.

Document all refusals,), rig gyrations, and physical conditions of samplers. 2.3 Well Construction 2.3.1 Casing/Screen Typically, only polyvinyl chloride (PVC), Teflon (polytetrafluoroethylene or PTFE), and/or stainless steel will be used. All well screens will be commercially fabricated, slotted or continuously wound, and have an inside diameter (ID) equal to or greater than the ID of the well casing. An exception may be needed in the case of continuously wound screens because their supporting rods may reduce the full ID. Stainless steel screens may be used with PVC or PTFE well casing. No fitting will restrict the ID of the joined casing and/or screen. All screens, casings, and fittings will be new. Screens will have the largest open area per unit length that is practical for the adjacent aquifer and available filter. Couplings within the casing and between the casing and screen will be compatibly threaded. Thermal or solvent welded couplings on plastic pipe will not be used. This also applies to threaded or slip-joint couplings thermally welded to the casing by the manufacturer or in the field. Each cap will be constructed to preclude binding to the well casing due to tightness of fit, unclean surface, or frost, and secure enough to preclude debris and insects from entering the well. Caps and risers may be threaded; however, sufficient annular space will be allowed between the well and protective casing to enable one to thaw any frosted shut caps. Preferably, unfiltered vents will not be placed in these caps or in the well riser/stickup. Unfiltered vents may compromise water sample integrity by allowing foreign materials to enter the well between sampling events. Caps will be loose enough to allow equilibration between hydrostatic and TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 6 of 12 atmospheric pressures or have filtered vents. Special cap (and riser) designs will be provided for wells in floodplains and those instances where the top of the well may be below grade, e.g., in roadways and parking lots. The use of well centralizers will be considered for wells deeper than 20 ft. When used, they will be of PVC, PTFE, or stainless steel and attached to the casing at regular intervals by means of stainless steel fasteners or strapping. Centralizers will not be attached to the well screen or to that part of the well casing exposed to the granular filter or bentonite seal. Centralizers will be oriented to allow for the unrestricted passage of the tremie pipe(s) used for filter pack and grout placement. 2.3.2 Filter Pack All granular filters will be approved prior to drilling and will be discussed in the work plans. Discussions will include composition, source, placement, and gradation. If the actual gradation is to be determined during drilling, then more than one filter pack gradation will be on hand so that well installation will not be unnecessarily delayed. Granular filter packs will be visually free of material that would pass through a No. 200 (75- micrometer (µm)) sieve, inert, siliceous, composed of rounded grains, and of appropriate size for the well screen and host environment. The filter material will be packaged in bags by the supplier and therein delivered to the site. 2.3.2 Bentonite Seal Bentonite is the only material that is allowed for sealing or as drilling mud under normal circumstances. This includes any form of bentonite (powders, granules, or pellets) intended for drilling mud, grout, seals, etc. Chips or pellets of an appropriate size depending on the annular space available will be used to form the well seal. If chips are used, they should be sieved to remove fine-grained material. Organic additives will not be used in drilling mud. An exception might be made for some high yield bentonites, to which the manufacturer has added a small quantity of polymer. The use of any bentonite will be discussed in the work plans. Bentonite will TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 7 of 12 only be used if absolutely necessary to ensure that the borehole will not collapse or to improve cuttings removal. 2.3.3 Grout Grout, when used in monitor well construction or borehole/well abandonment, will be composed of Portland cement, bentonite (0-10% dry bentonite per 94-lb sack of dry cement), and a maximum 6 to 7 gallons of approved water per sack of cement. The amount of water per sack of cement required for a pumpable mix will vary with the amount of bentonite used. The amount of water used will be kept to a minimum. Neither additives nor borehole cuttings will be mixed with the grout. All grout materials will be combined in an aboveground rigid container or mixer, and mechanically (not manually) blended on-site to produce a thick, lump-free mixture throughout the mixing vessel. The mixed grout will be recirculated through the grout pump prior to placement. Grout will be placed using a grout pump and pipe/tremie. The grout pipe will be of rigid construction for vertical control of pipe placement. Drill rods, rigid PVC, or metal pipes are suggested stock for tremie pipes. If hoses or flexible plastics must be used, they may have to be fitted with a length of steel pipe at the downhole end to keep the flexible material from curling and embedding itself into the borehole wall. This is especially true in cold weather when the coiled material resists straightening. Grout pipes will have side discharge. The side discharge will help to maintain the integrity of the underlying material (especially the bentonite seal). 2.4 Water Source To the extent practical, the use of drilling water will be held to a minimum. When water usage is deemed necessary, the source of any water used in drilling, grouting, sealing, filter placement, well installation, well decommissioning/abandonment, equipment washing, etc. will be approved prior to arrival of the drilling equipment on-site and specified in the work plans. If a suitable source exists on-site, that source will be used. The drilling subcontractor will have the responsibility to procure, transport, and store the water required for project needs in a manner to avoid the chemical contamination or degradation of the water once obtained. The drilling subcontractor will also be responsible for any heating, thermal insulation, or agitation of the water to maintain the water as a fluid for its intended uses. TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 8 of 12 2.5 Delivery, storage, and handling of materials Materials will be delivered to the site and stored in a secure area. Subcontractors are generally responsible for scheduling delivery and ordering those supplies pertaining to the installation of wells. An inventory will be kept to track the materials. Perishable materials will be covered with tarps and secured to prevent water damage. All materials will be handled in a safe manner and in accordance with health and safety protocols 3. WELL INSTALLATION 3.1 Preparation Every morning before entering the field, the field team and drilling subcontractor will meet to discuss the location and construction criteria for the day’s activities. The field geologist will also ensure that the drilling subcontractor obtains all necessary supplies for the day’s work (e.g., bentonite, Portland cement, and screen and riser), and has decontaminated all equipment and manmade construction materials to be used downhole (e.g., PVC or stainless-steel screen and riser). All available areal data (e.g., borehole logs) should be reviewed to determine expected formation depths prior to the day’s drilling. 3.2 Documentation During any activities pertaining to well construction, abandonment, or development, the field geologist will note in the GEOLIS logbook the following information: Length of time required to perform all drill rig activities (e.g., overdrilling, well construction, abandonment/grouting, development times, and pumping rates). All well construction/abandonment supplies used (e.g., bentonite, Portland cement, filter sand, and screen/riser footage). Any difficulties in well construction, development, or abandonment. This information may be used to substantiate a change of scope or explain anomalous sampling data. Exact measurements (using a tape measure) of screen, end cap trap, and riser lengths.

WELL COMPLETION 4.1 Background Elements of well protection are intended to protect the monitoring well from physical damage, to prevent erosion and/or ponding in the immediate vicinity of the monitoring well, and to enhance the validity of the water samples. The potential for physical damage is lessened by the installation of padlocked, protective iron/steel casing over the monitor well and iron/steel posts around the well (when needed for protection). The casing and posts will be new. The protective casing diameter or minimum dimension will be 2 in. greater than the nominal diameter of the monitor well, and the nominal length will be 5 ft. The concrete/cement filled posts will be at least 3 in. in diameter and the top modified to preclude the entry of water. Nominal length of the posts will be 6 ft. Special circumstances necessitating different materials will be addressed in the work plan. Erosion and/or ponding in the immediate vicinity of the monitoring well may be prevented by assuring that the ground surface slopes away from the monitor well protective casing by the installation of a 2-ft by 2-ft coarse gravel blanket around the well. Wells will contain a locking cover on the protective casing. The cover will be hinged or telescoped, but not threaded. All locks on these covers should be opened by a single key, if possible. 4.2 Aboveground well completion Aboveground wells will be completed as follows: Extend the well casing 2 to 3 feet above ground surface. Provide an end plug or casing cap for each well. Use a filtered vented cap or drill a small (0.125- inch) hole into the PVC riser just below the PVC cap or into the PVC cap to allow air circulation in the well. Shield the extended well casing with a carbon steel protective casing that is set over the well casing and cap and extends to a depth of 3 ft bgs. Grout the annular space between the borehole and the protective casing with cement/bentonite grout to a depth of 4 ft bgs. TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 10 of 12 Fill the annular space between the well casing and the protective casing with pure sodium bentonite slurry to protect the well casing from frost heave. Construct a 2- by 2-foot by 4-inch coarse gravel blanket at the surface, sloped away from the protective casing. Drill a small diameter hole (0.25- to 0.375-inch) in the protective casing (weep hole) near the top of the cement pad to allow for drainage and mark a survey location on the inner casing (mark with an indelible marker or cut a small notch in the PVC on the side toward the hinge). Install a lockable cap or lid on the protective casing. Mark the well number clearly on the protective casing cap using impact lettering. Install three 3-inch-diameter, concrete-filled steel guard posts, if directed to do so by the on-site geologist. The guard posts will be 6 feet in total length and installed radially from each well head. Recess the guard posts approximately 2 feet into the ground outside of the cement pad and set in concrete approximately 3 to 5 feet from the protective casing. Fill each guard post with concrete. All wells will be secured as soon as possible after drilling. Corrosion-resistant locks will be used for both flush and aboveground well assemblies. The locks must have extended shanks. 4.3 Flush-mounted well completion Groundwater monitoring wells will be completed aboveground at most locations. Where well stickup is of concern, the well will be completed as a flush mount, level with the ground surface. Flush-mounted wells will be completed as follows: Cut the casing 2 to 3 in. bgs and install a protective locking lid consisting of a cast iron valve box assembly or manhole cover. Center the lid assembly in a 3-foot-diameter concrete pad sloped away from the valve box. Provide a cap with a filtered vent for equilibrium and to prevent infiltration of surface water. Maintain a minimum of 1 foot of clearance between the casing top and the bottom of the valve box. Clearly mark the well number on the valve box lid and well casing using an impact-labeling method, and mark a surveying point on the inner casing. TETRA TECH, INC. Standard Operating Procedure Revision Date: 4/21/2023 Created by: Anthony Camacho Project name: Recycled Earth Page 11 of 12 5. MAINTENCE Wells need to be examined periodically (normally during sampling) to determine if they have been damaged, vandalized, or otherwise compromised, and to check for evidence of disintegration such as cracked casing, pads, or surface seals, and to check the security of the well (locked cap).

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. N2 Analyte reported using a calibration and validation based on Azobenzene (CAS 103-33-3). 1,2-Diphenylhydrazine decomposes into Azobenzene during the analysis. T8 Sample(s) received past/too close to holding time expiration. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577056 01/30/23 10:45 35 of 38 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577056 01/30/23 11:15 35 of 38 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577056 01/30/23 10:45 36 of 38 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577056 01/30/23 11:15 36 of 38 ANALYTICAL REPORT January 26, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1577067 Samples Received:01/18/2023 Project Number:RECYCLED EARTH Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: January 26, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This report presents the results from the analyses performed on two samples submitted by a representative of Pace Analytical National. The samples were analyzed for the presence or absence of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) using a modified version of USEPA Method 8290. The reporting limits were set to correspond to the lowest calibration point and a nominal 1-Liter sample amount, and the sensitivity was verified by signal-to-noise measurements. The quantitation limits, adjusted for sample extraction amount, may be somewhat higher or lower than the reporting limits provided in this report. The recoveries of the isotopically-labeled TCDD internal standard in the sample extracts ranged from 40-64%. Except for one low value, which was flagged "R" on the results table, the labeled internal standard recoveries obtained for this project were within the 40-135% target range specified in Method 8290. Also, since the quantification of the native TCDD was based on isotope dilution, the data were automatically corrected for recovery and accurate values were obtained. A laboratory method blank was prepared and analyzed with each sample batch as part of our routine quality control procedures. The results show the blanks to be free of 2,3,7,8-TCDD at the reporting limit. Laboratory spike samples were also prepared using clean reference matrix that had been fortified with native standard material. The results show that the spiked native TCDD was recovered at 104-111% with a relative percent difference of 6.5%. These results were within the target ranges for the method. Matrix spikes were not prepared with the sample batch.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. N2 Analyte reported using a calibration and validation based on Azobenzene (CAS 103-33-3). 1,2-Diphenylhydrazine decomposes into Azobenzene during the analysis. T8 Sample(s) received past/too close to holding time expiration. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577038 01/27/23 10:56 35 of 39 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577038 01/27/23 15:35 35 of 39 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577038 01/27/23 10:56 36 of 39 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1577038 01/27/23 15:35 36 of 39 ANALYTICAL REPORT January 26, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1577040 Samples Received:01/18/2023 Project Number:RECYCLED EARTH Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: January 26, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This report presents the results from the analyses performed on two samples submitted by a representative of Pace Analytical National. The samples were analyzed for the presence or absence of 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) using a modified version of USEPA Method 8290. The reporting limits were set to correspond to the lowest calibration point and a nominal 1-Liter sample amount, and the sensitivity was verified by signal-to-noise measurements. The quantitation limits, adjusted for sample extraction amount, may be somewhat higher or lower than the reporting limits provided in this report. The recoveries of the isotopically-labeled TCDD internal standard in the sample extracts ranged from 53-69%. Except for one low value, which was flagged "R" on the results table, the labeled internal standard recoveries obtained for this project were within the 40-135% target range specified in Method 8290. Also, since the quantification of the native TCDD was based on isotope dilution, the data were automatically corrected for recovery and accurate values were obtained. A laboratory method blank was prepared and analyzed with each sample batch as part of our routine quality control procedures. The results show the blanks to be free of 2,3,7,8-TCDD at the reporting limit. Laboratory spike samples were also prepared using clean reference matrix that had been fortified with native standard material. The results show that the spiked native TCDD was recovered at 104-111% with a relative percent difference of 6.5%. These results were within the target ranges for the method. Matrix spikes were not prepared with the sample batch.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. 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. T8 Sample(s) received past/too close to holding time expiration. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1586780 02/20/23 13:42 16 of 21 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1586780 02/20/23 13:46 16 of 21 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1586780 02/20/23 13:42 17 of 21 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1586780 02/20/23 13:46 17 of 21 ANALYTICAL REPORT February 16, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1582929 Samples Received:02/07/2023 Project Number: Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: February 16, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. P RPD between the primary and confirmatory analysis exceeded 40%. 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: Tetra Tech Inc. - UT L1582929 02/16/23 16:23 46 of 49 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1582929 02/16/23 16:33 46 of 49 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1582929 02/16/23 16:23 47 of 49 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1582929 02/16/23 16:33 47 of 49 ANALYTICAL REPORT February 17, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1584351 Samples Received:02/10/2023 Project Number: Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: February 17, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J1 Surrogate recovery limits have been exceeded; values are outside upper control limits. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. 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.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. 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. J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description 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. P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1594238 03/24/23 15:58 46 of 48 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1594238 03/24/23 16:01 46 of 48 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1594238 03/24/23 15:58 47 of 48 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1594238 03/24/23 16:01 47 of 48 ANALYTICAL REPORT May 11, 2023 Revised Report Tetra Tech Inc. - UT Sample Delivery Group:L1607939 Samples Received:04/21/2023 Project Number: Description: Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: May 11, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. E The analyte concentration exceeds the upper limit of the calibration range of the instrument established by the initial calibration (ICAL). 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. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1607939 05/11/23 11:53 196 of 206 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1607939 05/11/23 11:57 196 of 206 GLOSSARY OF TERMS Qualifier Description O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. P RPD between the primary and confirmatory analysis exceeded 40%. P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit. 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: Tetra Tech Inc. - UT L1607939 05/11/23 11:53 197 of 206 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1607939 05/11/23 11:57 197 of 206 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1607939 05/11/23 11:53 198 of 206 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1607939 05/11/23 11:57 198 of 206 ANALYTICAL REPORT May 19, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1613187 Samples Received:05/05/2023 Project Number: Description: Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: May 19, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description 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. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 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: Tetra Tech Inc. - UT L1613187 05/19/23 15:40 51 of 54 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1613187 05/22/23 10:29 51 of 54 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1613187 05/19/23 15:40 52 of 54 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1613187 05/22/23 10:29 52 of 54 ANALYTICAL REPORT May 20, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1614172 Samples Received:05/09/2023 Project Number: Description: Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: May 20, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. P RPD between the primary and confirmatory analysis exceeded 40%. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1614172 05/20/23 13:08 58 of 61 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1614172 05/22/23 10:40 58 of 61 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1614172 05/20/23 13:08 59 of 61 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1614172 05/22/23 10:40 59 of 61 ANALYTICAL REPORT June 05, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1615666 Samples Received:05/12/2023 Project Number: Description: Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: June 05, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. 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. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. O1 The analyte failed the method required serial dilution test and/or subsequent post-spike criteria. These failures indicate matrix interference. P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit. Q Sample was prepared and/or analyzed past holding time as defined in the method. Concentrations should be considered minimum values. T8 Sample(s) received past/too close to holding time expiration. 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: Tetra Tech Inc. - UT L1615666 06/05/23 14:25 70 of 81 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1615666 06/05/23 14:29 70 of 81 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1615666 06/05/23 14:25 71 of 81 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1615666 06/05/23 14:29 71 of 81 ANALYTICAL REPORT June 20, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1623675 Samples Received:06/07/2023 Project Number:RECYCLED EARTH Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: June 20, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. 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: Tetra Tech Inc. - UT RECYCLED EARTH L1623675 06/20/23 13:53 30 of 32 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1623675 06/20/23 14:44 30 of 32 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1623675 06/20/23 13:53 31 of 32 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT RECYCLED EARTH L1623675 06/20/23 14:44 31 of 32 ANALYTICAL REPORT July 03, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1629899 Samples Received:06/10/2023 Project Number: Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: July 03, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

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 B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1629899 07/03/23 14:29 11 of 14 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1629899 07/03/23 15:27 11 of 14 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1629899 07/03/23 14:29 12 of 14 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1629899 07/03/23 15:27 12 of 14 ANALYTICAL REPORT June 22, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1624935 Samples Received:06/10/2023 Project Number: Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: June 22, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description J The identification of the analyte is acceptable; the reported value is an estimate. J2 Surrogate recovery limits have been exceeded; values are outside lower control limits. J3 The associated batch QC was outside the established quality control range for precision. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 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: Tetra Tech Inc. - UT L1624935 06/22/23 14:44 35 of 37 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1624935 06/22/23 14:50 35 of 37 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1624935 06/22/23 14:44 36 of 37 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1624935 06/22/23 14:50 36 of 37 ANALYTICAL REPORT July 13, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1631472 Samples Received:06/30/2023 Project Number:117-9187001 Description:Recycled Earth 117-9187001 Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: July 13, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

[this will only be present on a dry report basis for soils]. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. 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. J4 The associated batch QC was outside the established quality control range for accuracy. J5 The sample matrix interfered with the ability to make any accurate determination; spike value is high. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT 117-9187001 L1631472 07/13/23 15:54 73 of 75 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT 117-9187001 L1631472 07/13/23 16:16 73 of 75 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT 117-9187001 L1631472 07/13/23 15:54 74 of 75 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT 117-9187001 L1631472 07/13/23 16:16 74 of 75 ANALYTICAL REPORT July 24, 2023 Tetra Tech Inc. - UT Sample Delivery Group:L1635984 Samples Received:07/15/2023 Project Number: Description:Recycled Earth Report To:Anna Rasmuson 4750 West 2100 South Suite 400 Salt Lake City, UT 84120 Entire Report Reviewed By: July 24, 2023 [Preliminary Report] Chris Ward Project Manager Results relate only to the items tested or calibrated and are reported as rounded values.

Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name, Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received. Abbreviations and Definitions MDL Method Detection Limit. ND Not detected at the Reporting Limit (or MDL where applicable). RDL Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. (S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. 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. J4 The associated batch QC was outside the established quality control range for accuracy. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1635984 07/24/23 22:35 30 of 32 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1635984 07/25/23 10:37 30 of 32 Pace Analytical National 12065 Lebanon Rd Mount Juliet, TN 37122 Alabama 40660 Nebraska NE-OS-15-05 Alaska 17-026 Nevada TN000032021-1 Arizona AZ0612 New Hampshire 2975 Arkansas 88-0469 New Jersey–NELAP TN002 California 2932 New Mexico ¹TN00003 Colorado TN00003 New York 11742 Connecticut PH-0197 North Carolina Env375 Florida E87487 North Carolina ¹DW21704 Georgia NELAP North Carolina ³41 Georgia ¹923 North Dakota R-140 Idaho TN00003 Ohio–VAP CL0069 Illinois 200008 Oklahoma 9915 Indiana C-TN-01 Oregon TN200002 Iowa 364 Pennsylvania 68-02979 Kansas E-10277 Rhode Island LAO00356 Kentucky ¹ ⁶KY90010 South Carolina 84004002 Kentucky ²16 South Dakota n/a Louisiana AI30792 Tennessee ¹ ⁴2006 Louisiana LA018 Texas T104704245-20-18 Maine TN00003 Texas ⁵LAB0152 Maryland 324 Utah TN000032021-11 Massachusetts M-TN003 Vermont VT2006 Michigan 9958 Virginia 110033 Minnesota 047-999-395 Washington C847 Mississippi TN00003 West Virginia 233 Missouri 340 Wisconsin 998093910 Montana CERT0086 Wyoming A2LA A2LA – ISO 17025 1461.01 AIHA-LAP,LLC EMLAP 100789 A2LA – ISO 17025 ⁵1461.02 DOD 1461.01 Canada 1461.01 USDA P330-15-00234 EPA–Crypto TN00003 ACCREDITATIONS & LOCATIONS ¹ Drinking Water ² Underground Storage Tanks ³ Aquatic Toxicity ⁴ Chemical/Microbiological ⁵ Mold ⁶ Wastewater n/a Accreditation not applicable * Not all certifications held by the laboratory are applicable to the results reported in the attached report. * Accreditation is only applicable to the test methods specified on each scope of accreditation held by Pace Analytical. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1635984 07/24/23 22:35 31 of 32 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Tetra Tech Inc. - UT L1635984 07/25/23 10:37 31 of 32 _6479884.1 Appendix H French Drain Excavation Table H‐1: French Drain Arsenic Confirmation Samples Results Sample name Sample Detection (mg/kg) FD1‐CS1 3.0 FD1‐CS2 6.8 FD1‐CS3 7.2 Notes: mg/kg = milligram per kilogram Background threshold value is equal to 15 mg/kg for arsenic.
