This amendment included an extension of the due diligence period for the HRA to complete a Phase II Environmental Assessment and utilize that information to determine if the City wishes to take ownership of the 2534 Kenzie Terrace parcel. The report from WSB and the City Engineer’s summary is attached. In short: The western portion of the 2534 Kenzie Terrace property contains low levels of petroleum and nonpetroleum compounds in soil, groundwater, and soil vapor. Soil and groundwater contamination was identified at a depth of 10 feet or more below grade. City is required to manage impacted materials generated/encountered during future construction activities (e.g., disposing excavated contaminated soil at a permitted landfill). Although there is not a pre-determined plan for City usage of the parcel, comments surrounding potential ownership have all included a future monument sign and green space of some kind. This type of use should not require any immediate remediation of the contamination. However, enrolling the property into the MPCA’s Brownfields Program will make the site eligible for grant funding for remediation when timing is determined to be appropriate, or is required based on changes at the site. As a result, staff recommends the HRA acquire the parcel per the Land Swap Agreement approved at its meeting on April 26, 2022.

WSBs determined that western portion of the 2534 Kenzie Terrace property contains low levels of petroleum and nonpetroleum compounds in soil, groundwater, and soil vapor. However, based on the proposed redevelopment of the property as a City welcome sign, it is not likely that contaminated soil or groundwater will be encountered during this proposed construction. The City is not required to clean up the contamination prior to or after purchase. Rather, the City is only required to manage impacted materials generated/encountered during future construction activities (e.g., disposing excavated contaminated soil at a permitted landfill). Soil and groundwater contamination was identified at a depth of 10 feet or more below grade during the environmental investigation. Voluntary parties can seek liability assurance letter(s) from the MPCA stating that they will not be held responsible for contamination identified at a property and/or confirming that the identified contamination does not pose a risk to human health or the environment, based on the current or proposed property use. As a result, it is recommended that the City enroll the property into the MPCA’s Brownfields Program for technical assistance and to request eligible lability assurance letters. One such letter is a No Association Determination (NAD), which is a determination from the MPCA that the specific actions proposed by the voluntary party will not associate them with the identified contamination. It is also recommended that the City prepare a Construction Contingency Plan (CCP) prior to construction. The CCP will outline the required methods and procedures to be followed in the event that contamination is encountered during redevelopment. Honorable Mayor, City Council and Staff C/O Charlie Yunker, City Manager June 8, 2022 Page 2 If you have any questions, I will be present at the June 14, 2022, Council Meeting to discuss with you or please call me at 612.388.9652.

Introduction WSB was retained by the City of Saint Anthony Village (City) to conduct a Phase II Environmental Site Assessment (ESA) at the vacant property located at 2534 Kenzie Terrace in St. Anthony, Minnesota (Site). The Site consists of Hennepin County Parcel 0702923230015 and totals approximately 0.32 acres. The Site location is depicted in Figure 1. The objective of the Phase II ESA was to investigate the recognized environmental conditions (RECs) identified in the Phase I ESA completed by WSB and dated March 28, 2022 (see Section 1.2). WSB understands that the investigation results will be used for future Site transaction/acquisition purposes. This Phase II ESA has been prepared exclusively for the City. No additional parties can rely on the information in this report without written permission from WSB. 1.1 Site Description and Background The Site was historically occupied by a filling station and car wash from before 1938 until approximately the 1960s. By the early-1970s, the Site was cleared and graded. The Site has been developed as vacant lot since the late-1970s. The Site is in a commercial and residential district of St. Anthony with commercial properties to the east and northwest and residential properties to the north and south. 1.2 Previous Investigations WSB completed a Phase I ESA for the Site, and the results of the assessment were summarized in a report dated March 28, 2022 (2022 Phase I ESA). The 2022 Phase I ESA identified the following RECs in connection with the Site: REC-1: Former Property Filling Station Based on a review of historical aerial photographs and city directories, the Site was developed with a filling station (Kenzie Company Gas Station) as early as 1938 until the late-1960s. By the early-1970s, the Site was cleared and graded. The former filling station is not listed under any regulatory databases and details related to the former underground storage tanks (USTs), including the size and contents, are not known. Further, documentation regarding the removal of UST systems, fueling lines, dispensers, etc. are not available. Undocumented petroleum releases may have occurred at the former UST system and associated filling station activities resulting in soil, groundwater, and/or soil vapor impacts at the Site. It is also possible that the USTs remain in-place at the Site and were never removed. The former Site filling station is considered a REC. REC-2: Former East Adjacent Dry Cleaner with Documented Contamination (MPCA ID BF0001960) The east adjacent property located at 2510/2512/2520 Kenzie Terrace is associated with active Brownfields/Voluntary Investigation and Cleanup (VIC) listing BF0001960. The east adjacent property was historically occupied by a dry cleaner (Popko Cleaners & Tailors) from approximately 1983 to 1988. The dry cleaner occupied the current building at 2510/2512 Kenzie Terrace, located approximately 15 feet from the Site. A subsurface investigation completed in July 2021 identified elevated concentrations of non-petroleum volatile organic compounds (VOCs), including tetrachloroethene (PCE) and trichloroethene (TCE), in groundwater and/or sub-slab soil vapor at the east adjacent property. Based on the sub-slab soil vapor results, the MPCA required an active vapor mitigation system to be installed on an expedited schedule at both property buildings in October 2021. The 2021 subsurface investigation also identified elevated concentrations of diesel range organics (DRO) in groundwater approximately 10 feet east of the Site. Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 2 Based on the active regulatory status and proximity to the Site, it is possible that the petroleum and chlorinated solvent impacts at the east adjacent property have migrated onto the Site via groundwater migration. The documented petroleum and chlorinated solvent contamination at the east adjacent property are considered a REC. REC-3: Former Northwest Adjacent Dry Cleaner and Filling Station with Documented Contamination (MPCA IDs BF0000517, SA0000618) The northwest adjacent property located at 2401 Lowry Avenue Northeast is associated with active Brownfields/VIC listing BF0000517 and Site Assessment listing SA0000618. The northwest adjacent property was occupied by a filling station (Lowry Grove Filling Station) from approximately 1938-1941 and a dry cleaner (Pilgrim Cleaners) in the 1960s and 1970s. The property was redeveloped with the current bank building in 1979. A subsurface investigation completed at the property in August and October 2017 identified elevated concentrations of silver, dibromochloromethane, cis-1,2-dichloroethene (cis-1,2- DCE) and polycyclic aromatic hydrocarbons (PAHs) in soil. Concentrations of benzene, PCE, TCE, and cis-1,2-DCE were identified in groundwater at concentrations greater than their respective Minnesota Department of Health (MDH) Health Risk Limits (HRLs). Elevated TCE concentrations were identified in sub-slab soil vapor samples collected from within the current bank building footprint. Further, elevated concentrations of non- petroleum VOCs, including PCE, TCE, and cis-1,2-DCE, were identified in soil vapor samples collected across the property parking lot. Based on the active regulatory status, distance to the Site (within 100 feet), and presumed direction of groundwater flow to the south, it is possible that the petroleum and chlorinated solvent impacts at the northwest adjacent property have migrated onto the Site via groundwater migration. The documented petroleum and chlorinated solvent contamination at the northwest adjacent property are considered a REC. REC-4: North Adjacent Property with Documented Contamination (LS0018847, BF0000058, BF0001790) The north adjacent property located at 2501 Lowry Avenue Northeast is associated with active Brownfields/VIC listing BF0001790, inactive Brownfields/VIC listing BF0000058 and inactive leak listing LS0018847. A petroleum release was reported at the north adjacent property in August 2012 during the removal of one 12,000-gallon fuel oil UST. The UST was reportedly installed in 1965. The MPCA issued closure of the leak site in March 2013 following the completion of a limited site investigation. Additional subsurface investigations were completed at the north adjacent property prior to redevelopment in May 2016 and January 2021. The May 2016 investigation identified elevated concentrations of TCE, PCE, and cis-1,2-DCE in groundwater and elevated concentrations of PCE in soil vapor. The January 2021 investigation also identified elevated PCE and benzene concentrations in soil vapor at the property. Based on the soil vapor results, the MPCA required a vapor mitigation system to be installed at any proposed buildings at the property. The documented chlorinated solvent impacts were presumed to be associated with former dry cleaners located west (Pilgrim Cleaners) and south (Popko Cleaners & Tailers) of the property. Based on the active regulatory status, distance to the Site (within 100 feet), and presumed direction of groundwater flow to the south, it is possible that the petroleum and chlorinated solvent impacts at the north adjacent property have migrated onto the Site via groundwater migration. The documented petroleum and chlorinated solvent contamination at the north adjacent property are considered a REC. Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 3 1.3 Scope of Work The following tasks were conducted as part of the Phase II ESA: Completed a public utility locate through Gopher State One Call (GSOC) service as well as a private utility locate prior to boring advancement. Advanced four borings to depths ranging from 24 to 28 feet below grade using a push probe drill rig for soil and/or groundwater sample collection. Advanced four borings to depths of 4 feet below grade using a push probe drill rig for soil vapor sample collection. Assessed soil samples for visual and/or olfactory indications of contamination and screened soil samples for organic vapors using a photoionization detector (PID) equipped with a 10.6 electron volt (eV) lamp. Soil types and profiles were recorded on boring logs in general accordance with the Unified Soil Classification System (USCS). Utilized Global Positioning System (GPS) technology to record final boring locations. Collected and submitted select soil samples for analysis of: o Diesel range organics (DRO) by the Wisconsin Modified Method o Gasoline range organics (GRO) by the Wisconsin Modified Method o VOCs by Environmental Protections Agency (EPA) Method 8260D o Resource Conservation and Recovery Act 8 Metals (RCRA 8 Metals) by EPA Method 6020B/7471B Collected and submitted select groundwater samples for analysis of: o DRO by the Wisconsin Modified Method o GRO by the Wisconsin Modified Method o VOCs by EPA Method 8260D o RCRA 8 Metals by EPA Method 6010/7471 (field filtered for analysis of dissolved metals) Collected and submitted soil vapor samples for analysis of: o VOCs by EPA Method TO-15, full scan Sealed all borings in accordance with Minnesota Department of Health (MDH) requirements. Prepared this report detailing field observations, laboratory results, conclusions, and recommendations. Details of the tasks completed during this investigation are discussed in the following sections. General field methods are included as Appendix A. 1.4 Work Plan Deviations The work was completed in general accordance with WSB’s scope of work, dated March 31, 2022, except for the following deviations: Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 4 Adjusted Boring Depths Borings B-2 and B-4 encountered bedrock refusal at depths ranging from 24 to 24.5 feet below grade. As a result, these borings were not advanced to the proposed depth of 28 feet below grade. Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 5 2. Investigation A total of 8 environmental borings (B-1 through B-4 and V-1 through V-4) were advanced at the Site on April 22, 2022, to investigate potential impacts to soil, groundwater, and soil vapor. The environmental borings were completed by Bergerson-Caswell, Inc. of Maple Plain, Minnesota using a truck-mounted push probe drill rig. The boring locations are depicted on Figure 2. 2.1 Soil Sampling Continuous soil sampling was conducted at each boring using a four-foot long rod with a new acetate liner for each sample. The soil borings were advanced to depths that ranged from 24 to 28 feet below grade. Soil profiles were assessed at two-foot intervals and labeled accordingly. Each sample was visually examined for evidence of contamination, field classified, and screened for organic vapors using a PID equipped with a 10.6 eV lamp. Soil boring logs are included as Appendix B. Two soil samples were collected from each of the four soil borings during the investigation and submitted to Eurofins TestAmerica Laboratory of Cedar Falls, Iowa (Eurofins) for analytical testing. In general, soil samples were submitted for laboratory analysis in compliance with the MPCA guidance document 4-01 Soil and Groundwater Assessments Performed During Site Investigations and/or field observations. Following completion of sampling and screening activities, the borings were sealed with bentonite grout in accordance with MDH requirements. 2.2 Groundwater Sampling A total of two groundwater samples were collected and submitted to Eurofins for analytical testing. Groundwater samples were collected by installing a size 10 slotted polyvinyl chloride (PVC) screen (temporary well screen) into the boring, then inserting a section of new polyethylene tubing into the screened well interval. A check valve was used to draw the sample. Groundwater samples collected for RCRA Metals analysis were field filtered prior to laboratory analysis. Unique identification numbers were assigned to groundwater samples using the boring number and the designation of “GW” for groundwater. Water level measurements and screen depths are included in the soil boring logs in Appendix B. 2.3 Soil Vapor Sampling A total of four soil vapor samples were collected from a depth of 4 feet below grade and submitted to Eurofins for analytical testing. Each sample was collected using a one-liter summa canister equipped with a regulator calibrated to collect the sample with an approximate five- minute draw (i.e., a flow rate of 200 milliliters (mL) per minute). Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 6 3. Results 3.1 Soil Observations and Analytical Results A total of eight soil samples were collected and submitted for laboratory analysis. The soil results were compared to the MPCA Residential-Recreational Soil Reference Values (RR-SRVs), Commercial-Industrial SRVs (CI-SRVs), Screening Soil Leaching Values (SLVs), and MPCA unregulated fill criteria. For health based SRVs determined to be below background concentrations, Background Threshold Values (BTVs) were used as a comparison. A summary of the soil analytical testing results is included as Table 1. Concentrations that were found to exceed MPCA regulatory criteria are highlighted on Figure 3. A copy of the laboratory analytical report is included in Appendix C. The following is a summary of the soil sample observations and analytical testing results: Fill soils were encountered in the soil borings throughout the Site. The fill soil consisted primarily of fine to coarse sandy clay. Elevated PID readings (greater than 10 parts per million (ppm)) were identified in boring B-1 from 26 to 28 feet below grade (11.2 ppm); B-2 from 18 to 24.5 feet below grade (13.2-46 ppm); B-3 from 2 to 6 feet below grade (11.8-12.9 ppm), 8 to 10 feet below grade (10.3 ppm), and 16 to 26 feet below grade (10.8-38 ppm); and B-4 from 10 to 24 feet below grade (30.9-399 ppm). The PID screening results are included in the boring logs in Appendix B. Stained soil (gray) with a petroleum odor was encountered at boring B-4 from 10 to 18 feet below grade. Refusal was encountered in soil borings B-2 and B-4 at depths ranging from 24 to 24.5 feet below grade due to the presence of bedrock. Benzene was detected at a concentration of 0.172 milligrams per kilogram (mg/kg) in soil sample B-4 (14-16), which is above the Screening SLV of 0.017 mg/kg but below the RR- SRV and CI-SRV. Nine VOCs were detected above the laboratory reporting limits in soil sample B-4 (10-12) but below regulatory criteria. No other VOCs were detected at concentrations equal to or greater than the laboratory reporting limits in the remaining soil samples. Arsenic was detected at a concentration of 6.89 mg/kg in soil sample B-2 (10-12), which is above the Screening SLV of 5.8 mg/kg but below the RR-SRV and CI-SRV. No other RCRA Metals were detected at concentrations above regulatory criteria in the soil samples. DRO was detected in soil samples B-4 (10-12) and B-4 (14-16) at concentrations of 459 and 193 mg/kg, respectively, above the MPCA unregulated fill criteria of 100 mg/kg. GRO was detected in soil sample B-4 (10-12) at a concentration of 463 mg/kg, above the MPCA unregulated fill criteria of 100 mg/kg. GRO was detected in soil sample B-4 (14- 16) at a concentration 20.6 mg/kg, below regulatory criteria. 3.2 Groundwater Observations and Analytical Results A total of two groundwater samples (GW-1 and GW-4) were collected during this investigation. The groundwater sample results were compared to the MDH Health Based Guidance (HBG) Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 7 values, Environmental Protection Agency (EPA) Maximum Contaminant Levels (MCLs), and MPCA National Pollutant Discharge Elimination System (NPDES) General Industrial Pump-Out Permit (GIPP) criteria. For compounds where multiple HBG values or NPDES GIPP values were provided, the most stringent value provided was used for regulatory comparison. The HBG values include Health Risk Limits (HRLs), Health Based Values (HBVs), or Risk Assessment Advice (RAA) values. It should be noted that HRL, HBV, and RAA values are used as a proxy for evaluating the impacts to groundwater; however, for construction purposes the treatment limits for groundwater dewatering discharge would be established in the discharge permit for the project. Groundwater analytical results are summarized in Table 2. Concentrations that were found to exceed regulatory criteria are highlighted on Figure 4. A copy of the laboratory analytical report is included in Appendix C. The following is a summary of the groundwater observations and analytical testing results: Groundwater was encountered in boring B-1 at a depth of 22.7 feet below grade and boring B-4 at a depth of 11.8 feet below grade. Groundwater was not encountered in borings B-2 and B-3. No visual or olfactory evidence of contamination was observed in the groundwater sample. Benzene was detected at a concentration of 45.9 micrograms per liter (µg/l) in groundwater sample GW-4, which exceeds the MDH HRL of 2 µg/l. 1,2-Dichloroethane (1,2-DCA) was detected at a concentration of 68.2 µg/l in groundwater sample GW-4, which exceeds the MDH HRL of 1 µg/l. Five additional VOCs were detected at concentrations equal to or greater than the laboratory reporting limits in groundwater sample GW-4 but below regulatory criteria. No VOCs were detected at concentrations equal to or greater than the laboratory reporting limits in groundwater sample GW-1. Dissolved arsenic and/or barium were detected at concentrations greater than the laboratory reporting limits but below regulatory criteria in groundwater samples GW-1 and GW-4. No other metals were detected at concentrations equal to or greater than the laboratory reporting limits in the groundwater samples. DRO was detected at a concentration of 1,220 µg/l in groundwater sample GW-4, exceeding the MPCA criteria for remedial investigation of 1,000 µg/l and the NPDES GIPP criteria of 200 µg/l. DRO was detected at a concentration of 245 µg/l in groundwater sample GW-1, exceeding the NPDES GIPP criteria. GRO was detected at a concentration of 378 µg/l in groundwater sample GW-4, exceeding the NPDES GIPP criteria of 200 µg/l. GRO was not detected at a concentration equal to or greater than the laboratory reporting limit in groundwater sample GW-1. 3.3 Soil Vapor Results A total of four soil vapor samples were collected during the investigation and submitted for laboratory analysis for VOCs. The soil vapor samples were collected from four feet below grade. For comparison purposes, the analytical results are compared to 33 times the MPCA Residential Intrusion Screening Values (ISVs) and Expedited Intrusion Screening Value (EISVs) and 33 times the MPCA Commercial/Industrial ISVs and EISVs. The 33X ISVs and EISVs were established to evaluate soil vapor risks and to predict the amount of a contaminant in indoor air that may result from vapor intrusion. Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 8 Soil vapor results are summarized in Table 3. Concentrations that were found to exceed MPCA regulatory criteria are highlighted on Figure 5. A copy of the laboratory analytical report is included in Appendix C. The following is a summary of the soil vapor analytical results: PID readings were 0.0 ppm while collecting the soil vapor samples. 1,3-Butadiene was detected above 33X the Residential ISV in soil vapor samples V-2 and V-4 at concentrations of 21 micrograms per cubic meter (µg/m3) and 46 µg/m3, respectively. Five additional VOCs (acetone, benzene, 2-propanol, propylene, and toluene) were detected in the soil vapor samples at concentrations greater than or equal to the laboratory reporting limits but below their respective 33X ISVs and EISVs.

Discussions and Conclusions This Phase II ESA was conducted to evaluate the RECs identified for the Site in the 2022 Phase I ESA prepared by WSB. Analytical soil, groundwater, and soil vapor exceedance maps are included as Figure 3, Figure 4, and Figure 5. The following discussion and conclusion information is provided: Through field observations and analytical testing, evidence of a release was discovered at boring B-4 at the western portion of the Site. At boring B-4, concentrations of benzene, DRO, and GRO in soil, benzene, 1,2-DCA, DRO, and GRO in groundwater, and 1,3-butadiene in soil vapor were detected above regulatory criteria. The release is potentially associated with the former filling station (Kenzie Company Gas Station) at the Site and/or with the former adjacent drycleaners. Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 10 5. Recommendations Based on the results of this Phase II ESA, WSB provides the following recommendations: Report the discovery of the release at the Site to the Minnesota Duty Officer. The MPCA will review the investigation data and determine if further environmental investigation (e.g., completion of additional borings and sampling) is warranted. Costs incurred related to the investigation and cleanup of a leak resulting for a tank system are eligible for reimbursement through the Minnesota Petrofund Program. Enroll the Site into the MPCA’s Brownfields Program for eligible technical assistance and/or contamination liability assurances related to the petroleum and non-petroleum impacts detected at the Site. The MPCA can review and approve future environmental investigation work plans, assist with obtaining desired contamination liability assurances (such as a No Association Determination (NAD) Letter) for the non-petroleum related compounds discovered at the Site. The MPCA charges $150 per hour to provide technical assistance and liability assurances. Phase II Environmental Site Assessment 2534 Kenzie Terrace WSB Project No. R-020198-000 Page 11 6.

Calibration of MiniRAE Lite Model 7300 PID Prior to each field usage, the MiniRAE Lite photoionization detector (PID) will be calibrated in the field using a 100-ppm isobutylene standard in accordance with the instructions outlined in the MiniRAE Lite User’s Manual. The results will be recorded on the calibration log located in the PID carrying case along with the date, time, and project information. An additional calibration verification check will be conducted by attaching the calibration gas to the instrument and then removing to make sure the instrument reading returns to zero. II. Soil Sample Collection, Screening, and Analysis Soil samples will be classified in the field consistent with the Unified Soil Classification System (USCS). Field notes will be maintained describing the sample collection location, soil composition, field methods, and environmental monitoring data such as visual and olfactory observations and photoionization detector (PID) results. Soil samples collected during sampling activities will be screened for the presence of organic vapors using a PID equipped with a 10.6 or 11.7 electron volt (eV) lamp depending on the type of contaminants expected. The PID will be calibrated prior to daily field activities. For each sample, a clean polyethylene freezer bag will be half filled with soil and immediately sealed. Any clumps of soil present in the bag will be manually broken up. The bag will be shaken for approximately 15 seconds and then stored for a minimum of 10 minutes for headspace development. The bag will then be shaken for another 15 seconds and the PID probe inserted through a small opening in the bag avoiding water droplets and soil particles. The highest PID reading within approximately 2 seconds after insertion will be recorded for each sample. A new pair of disposable nitrile gloves will be used during the collection of each sample to reduce cross contamination. Soil sampling tools will be decontaminated with Alconox detergent (or similar) and rinsed with distilled water prior to each sample collection. Soil samples selected for laboratory analysis will be placed in laboratory‐prepared containers, labeled, stored on ice, and shipped with the chain of custody form to a Minnesota‐certified laboratory. The respective sample containers will be labeled with the following information: Unique sample number Site name Name of sampler Time and date Desired analysis III. Water Level Measurement Water level measurements will be collected from the temporary wells using a battery powered tape-guided water level meter. The water level meter will be inspected and cleaned using an Alconox solution and rinsed with distilled water prior to each measurement to reduce the risk of cross contamination. If the probe encounters free product or highly contaminated groundwater, the probe decontamination process will include using a desorbing agent (dilute solution of water and isopropanol or methanol) followed by a thorough tap water rinse and a final distilled or deionized water rinse. Each boring will be allowed to rest for at least 5 minutes prior to measuring (this allows the well to adjust to the isostatic pressure). The distance from the ground surface elevation to the well water surface will be measured and recorded to the nearest 0.01 foot. The measurement results will be recorded on boring logs along with any other general well observations. IV. Hydraulic Push Probe Soil Borings Prior to boring activities, subsurface utility lines will be marked by Gopher State One Call, Minnesota’s on- call utility locating service. In some instances, a private utility locator may be retained to locate on-site and or private utilities. Soil boring installations will be accomplished by hydraulic push-probe boring methodology. Soil sampling will be facilitated by hydraulically pushing an approximate 2-inch outside diameter, stainless-steel rod to the desired test depth. Soil samples will be collected continuously or as needed from each boring for field logging and screening for volatile organic vapor concentrations. To avoid cross contamination of soil samples collected during boring activities, the hydraulic push-probe boring sampling equipment will be cleaned between boreholes utilizing an Alconox solution and rinsed with distilled water. V. Groundwater Sample Collection from Boreholes Groundwater samples will be collected through temporary screened PVC monitoring wells placed in the boreholes. Groundwater samples will be collected from these borings utilizing poly tubing with a check valve or a single use disposable bailer with new line. In some instances, the borehole will be purged with a peristaltic pump and tubing prior to sample collection. Upon collection, groundwater samples will be placed in laboratory-prepared containers and examined for evidence of impacts using visual and olfactory criteria. Samples will be labeled with the same sampling information noted above (see soil sample collection). Immediately following collection, samples will be placed on ice in a field cooler. Samples will be then transported to a Minnesota-certified laboratory with chain-of-custody documentation. VI. Soil Vapor Collection Soil vapor samples will be collected through temporary soil vapor points placed in the boreholes. Vapor samples will be collected from the borings by attaching a vapor tip to the probe, advancing the probe to the desired depth, retracting the rod approximately 6-24 inches to allow for a vapor gap, opening up the vapor tip, and then connecting a length of new poly tubing. The tubing is then purged using a hand pump, and then extracting the sample using a vapor sampling canister following the laboratory’s instructions. Samples will be then labeled with the same sampling information noted above (see soil sample collection). VII. Field Log Preparation Boring logs will be used to document subsurface conditions encounter during the field activities. If the surface is less than 6 inches thick the boring location surface material will be recorded in the “notes” column on the log. The sample interval, recovery, and PID volatile organic compound readings will be recorded for each sample interval. In general, the methods outlined in the Standard Practice for Description and Identification of Soils (ASTM D2488-93) will be used to describe soil. The soil descriptions will be described in the following order: A description of the main soil group within the sample (e.g., silty sand, clay, silt, etc.). If coarse-grained soil (i.e., sand or gravel) is present, then a brief description of the predominant particle grain size(s) (e.g., fine, medium, coarse) will be included. If fine grained soil (i.e., clay or silt) is present, then the consistency based on finger pressure (e.g., very soft = thumb will penetrate soil more than 1 inch, soft = thumb will penetrate soil about 1 inch, firm = thumb will penetrate soil about ¼ inch, hard = thumb will not indent soil, but thumbnail will easily make a mark, very hard = thumbnail will not indent soil) will be included. If another soil group is present in the sample its concentration with an adjective based on the percentages present within the sample (i.e., trace = < 5%, few = 5 to 10%, little = 10 to 25%, some = 30 to 45 %) will be included. The overall moisture of the soil sample using the terms dry, moist, or wet (do not use the term “saturated”) will be described. The color of the main soil group (e.g., brown, gray, etc.) will be described. The presence of any unusual occurrences (e.g., bricks, glass, debris, petroleum odor) will be noted. If the soil material is fill or probable fill, note in parenthesis [e.g., (fill), (probable fill). Soil description examples: Silty sand, fine to medium grained, with few gravel, moist, dark brown. Sandy clay with trace gravel, soft, wet, gray, petroleum odor (fill). If groundwater is encountered, the depth to water will be recorded on the log. In addition, the sample name, analysis, and time of all samples collected for analytical analysis will be also recorded in the “notes” column.

Receipt The samples were received on 4/23/2022 10:30 AM. Unless otherwise noted below, the samples arrived in good condition, and where required, properly preserved and on ice. The temperatures of the 2 coolers at receipt time were 1.4º C and 2.2º C. GC/MS VOA Method 8260D: The following samples were collected in a properly preserved vial; however, the pH was outside the required criteria when verified by the laboratory. The samples were analyzed within the 7-day holding time specified for unpreserved samples: GW-1 (310-229849-1) and GW-4 (310-229849-2). Method 8260D: The continuing calibration verification (CCV) associated with batch 310-351296 recovered above the upper control limit for 2-Chlorotoluene(21.1%D), 1,2,3-Trichloropropane(29.4%D), cis-1,3-Dichloropropene(21.1%D), trans-1,3-Dichloropropene(20.2%D), 1,1,2,2-Tetrachloroethane(26.9%D), 1,3-Dichloropropane(23.3%D), 4-Chlorotoluene(20.5%D), 4-Methyl-2-pentanone(25.8%D), and 1,1,1,2-Tetrachloroethane(20.4%D). The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported. The associated sample is impacted: (CCV 310-351296/3). Method 8260D: The method blank for preparation batch 310-351186 contained 1,2,4-Trimethylbenzene above the reporting limit (RL). None of the samples associated with this method blank contained the target compound; therefore, re-extraction and/or re-analysis of samples were not performed. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC VOA Method WI-GRO: The following samples were collected in properly preserved vials; however, the pH was outside the required criteria when verified by the laboratory. The sample was analyzed within the 7-day holding time specified for unpreserved samples: GW-1 (310-229849-1). Method WI-GRO: The following sample was collected in a properly preserved vial; however, the pH was outside the required criteria when verified by the laboratory. The sample was analyzed outside the 7-day holding time specified for unpreserved samples but within the 14-day holding time specified for preserved samples: GW-4 (310-229849-2). Method WI-GRO: Significant peaks, readily distinguished from background, were detected in the following sample before the analytical window defined by the first component eluting in the Gasoline Range Organics (GRO) mix (i.e., Methyl tert-butyl ether): GW-4 (310-229849-2). Method WI-GRO: Significant peaks, readily distinguished from background, were detected in the following samples within five minutes after the end of the analytical window defined by the last component eluting in the Gasoline Range Organics (GRO) mix (i.e., Naphthalene): B-4 (10-12) (310-229849-9) and B-4 (14-16) (310-229849-10). No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GC Semi VOA No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. Metals No analytical or quality issues were noted, other than those described in the Definitions/Glossary page. General Chemistry No analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 04/23/2022; the samples arrived in good condition. VOLATILE ORGANIC COMPOUNDS Samples V-1, V-2, V-3 and V-4 were analyzed for Volatile Organic Compounds in accordance with EPA Method TO-15. The samples were analyzed on 04/26/2022. Samples V-1[10X], V-2[10X], V-3[10X] and V-4[10X] required dilution prior to analysis. The reporting limits have been adjusted accordingly. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
