The Site is located in downtown High Point, Guilford County and is generally enclosed by Gatewood Avenue to the north, Lindsay Street to the west, English Street to the south, and Elm Street to the east. The Site is currently comprised of sixteen parcels. The parcels together total approximately 11.35 acres. The northern approximate half of the Site is being developed with a multi-use baseball stadium and includes approximately 6 acres. Five of the parcels (1, 2, 8, 9 and 10) front Church Avenue, four of the parcels (3, 4, 5 and a portion of 7) front Pine Street, two parcels (a portion of 7 and 12) front English Street, and six parcels (11, 13, 14, 15, 16, and 17) front Lindsay Street. Parcel 1 located at 210 Church Avenue is the location of the former High Point Enterprise. ECS performed a Phase I Environmental Site Assessment (ESA) of the former High Point Enterprise in February 2016. ECS identified the past use of the property as a printing company and paint factory as a recognized environmental condition (REC). ECS conducted A Phase II Environmental Site Assessment Report of the Enterprise property in July 2016 and of the northern portion of the Brownfields site (baseball stadium area). Analysis of groundwater samples collected in the footprint of the baseball stadium detected trichloroethene (TCE) at concentrations above the both the North Carolina Division of Waste Management’s residential and industrial/commercial Vapor Intrusion Screening Levels (VISL). Based on the results of the 2016 and 2017 groundwater assessments that identified the presence of TCE above 2018 residential VISL, the Brownfields Group required that an active vapor mitigation system (VMS) for the multi-use baseball stadium and a passive VMS for the Church Avenue ticket booth. The active VMS was installed and included a combination of a 20-mil vapor barrier and an active sub-slab depressurization system (SSDS) embedded in a gas permeable aggregate layer. The ground floor of the stadium was built using slab on grade construction techniques. The vapor barrier for this VMS was installed above a minimum 8-inch gas permeable aggregate layer and immediately below the slab of all occupied/enclosed spaces. The active sub-slab depressurization system (SSDS) was installed and is comprised of a GeoVent low-profile venting system, PVC header pipe, and PVC vent riser pipes. A large portion of the building includes waterproofing material installed on basement walls as part of this system. This report describes indoor air and soil gas sampling performed in April 2019 in areas of the stadium where the active VMS was installed. A separate report is being submitted to describe indoor air and soil gas sampling performed at Church Avenue ticket building where the passive VMS was installed. High Point Multi Stadium - Indoor Air and Soil Gas Sampling Report High Point, Guilford County, North Carolina Brownfields Project Number 21047-17-041 ECS Project No. 49-5318A June 11, 2019   2 2.0 SCOPE OF WORK Between April 5, 2019 and April 11, 2019 ECS collected 22 indoor air and 17 sub-slab soil gas samples inside the two stadium buildings (Service Level and Concourse Level) where the active vapor mitigation system (VMS) was installed. Prior to conducting the indoor air sampling, ECS personnel conducted a survey of chemicals in the ticket building. The stadium was under construction and construction supplies which included chemicals were present when sampling was performed. Indoor air and sub-slab soil gas sampling were conducted to help determine if a vapor intrusion (VI) concerns may exist in the buildings with regards to the chemical of concern (COC) TCE. The indoor air and sub-slab soil gas sampling were conducted in general accordance with the North Carolina Division of Waste Management’s (NCDWM) Vapor Intrusion Guidance document (March 2018, Version 2). 2.1 Survey of Chemicals A walk-through of the buildings was completed prior to sampling and the chemicals and products were documented in field notes and photographs. Photographs are included in Appendix A. The products documented generally consisted of paints, primers, caulking, adhesives, epoxies, and various cleaning supplies. ECS is awaiting the receipt of safety data sheets (SDSs) for the products from the general contractor (Samet Corporation). ECS will submit the SDSs digitally to the North Carolina Department of Environmental Quality (NCDEQ) after they are received. 2.2 Indoor Air Sampling In order for the building to remain closed and to minimize disturbance of the canisters, ECS collected the samples during the night when construction crews were not working in the buildings. Doors separating some of the rooms had not been installed to isolate these rooms which may be occupied for longer periods of time from common, more open areas. These doorways, windows, etc. were sealed to further minimize disturbance of the canisters during the sampling event. See photographs in Appendix A. The HVAC system had reportedly been in operation for approximately two weeks prior to the indoor air sampling event. The HVAC was operated for at least 48-hours prior to sampling in a manner similar to how it will operate when the stadium is open. On April 3, 2019 sixteen (16) indoor air samples (A-1 through A-16) were collected on the Service Level and six indoor air samples (A-17 through A-22) were collected on the Concourse Level of the stadium. The sample locations were selected based on areas where waterproofing was used on below-grade walls and/or areas such as locker rooms, restrooms, and suites that may be occupied for a longer period than other areas at the stadium. Prior to collection of the air samples, the sub-slab monitoring points were closed for a minimum of 48-hours. High Point Multi Stadium - Indoor Air and Soil Gas Sampling Report High Point, Guilford County, North Carolina Brownfields Project Number 21047-17-041 ECS Project No. 49-5318A June 11, 2019   3 The samples were collected using individually certified 6 liter (L) Summa canisters equipped with 8-hour flow restrictors. The samples were collected by placing each Summa canister at a height of approximately 5 feet above the floor during sampling. Photographs are included in Appendix A. After approximately seven hours, it was discovered that the Summa canisters for samples A-2 and A-5 were completely discharged. The samples from these canisters were not analyzed. Samples A-2 and A-5 were resampled on April 5, 2019. The sample containers were labeled, placed into protective packaging material and shipped to Pace Analytical Laboratories (Pace) in Minneapolis, Minnesota to be analyzed by EPA Method TO-15. ECS maintained proper chain-of-custody (COC) procedures throughout the sample collection and transportation process. A Copy of the COCs is included in Appendix B. ECS collected two duplicate indoor air samples for laboratory analysis by EPA Method TO-15. Sample Dup-1 was a duplicate of indoor air sample A-2 and sample Dup-2 was a duplicate of indoor air sample A-17. Concurrently with the indoor air sampling, one exterior (ambient) air sample (AA-1) was collected upwind for laboratory analysis by EPA Method TO-15. 2.3 Sub-Slab Soil Gas Sampling Between April 4, 2019 and April 11, 2019 ECS collected seventeen sub-slab soil gas samples from permanent sub-slab monitoring points (MP-1 through MP-17) installed by EAI-South. As shown in Figures 3 and 4, thirteen sub-slab soil gas samples were collected on the Service Level and four sub-slab soil gas samples were collected on the Concourse Level. Prior to collecting the soil gas samples, commercial grade helium gas was used as a quality assurance/control measure to confirm the integrity of the probe seal. A plastic container (approximately 10-20 gallons) or plastic sheeting was placed and sealed over the sampling point and sampling train and purged with the helium. The probe point tubing and tracer gas tubing was placed through the container wall via rubber grommets and a shroud was placed over the sample point and sample train leading to the purge valves and sample port. During the purging stage, the container was flooded with helium via the hose placed through the container wall. A Model MGD-2002 Multi-Gas Leak detector was connected to the probe tube and the air stream being purged with at least 3 volumes (volume to include total sampling train as well as the constructed point). Helium readings were collected from each volume, recorded in field notes, and included as part of this report (Appendix C). A helium concentration of less than five percent helium was considered acceptable. If concentrations greater than five percent helium were measured, the probe tube seal was reseated and the leak detection process was repeated. Photographs of the helium leak test set-up are included in Appendix A. Following the helium leak test, sub-slab soil gas samples MP-1 through MP-17 (Figure 3 and Figure 4) were collected using 1-liter Summa canisters at an approximate flow rate of 0.2 L/minute to collect soil gas samples over a 5-minute period. High Point Multi Stadium - Indoor Air and Soil Gas Sampling Report High Point, Guilford County, North Carolina Brownfields Project Number 21047-17-041 ECS Project No. 49-5318A June 11, 2019   4 3.0 LABORATORY ANALYSES A summary of the laboratory analytical data for indoor air samples is shown on Table 1. The following target analytes were detected at concentrations above the NCDEQ residential and non-residential VISLs in the samples indicated below: SAMPLE ID TARGET ANALYTES EXCEEDING RESIDENTIAL AND NON-RESIDENTIAL VISLS A-1 Ethylbenzene, m,p-xylene, o-xylene A-3 Ethylbenzene, m,p-xylene, o-xylene A-4 Ethylbenzene, m,p-xylene, o-xylene A-6 Ethylbenzene, m,p-xylene, o-xylene A-7 Ethylbenzene, TCE A-8 Ethylbenzene, m,p-xylene, o-xylene A-9 Ethylbenzene, m,p-xylene, o-xylene A-10 Ethylbenzene, m,p-xylene A-11 Ethylbenzene, m,p-xylene A-12 Ethylbenzene, m,p-xylene A-13 Ethylbenzene, m,p-xylene, o-xylene A-14 Ethylbenzene, m,p-xylene, o-xylene A-15 Ethylbenzene, m,p-xylene, o-xylene A-16 Ethylbenzene, m,p-xylene, o-xylene A-18 1,2,4-Trimethylbenzene, ethylbenzene . With the exception of sample A-7, TCE was not detected at concentrations exceeding non- residential VISLs for samples collected during the April 2019 indoor air sampling event. The laboratory data sheets are found in Appendix B. It should be noted that indoor air sampling was performed at the Church Avenue Ticket Building where the passive VMS was installed and these samples are also included in the laboratory report. A summary of the laboratory analytical data for sub-slab soil gas samples is shown on Table 2. Several VOCs were detected in one or more of the sub-slab soil gas samples but did not exceed either the residential or non-residential VISLs. 4.0 CONCLUSIONS AND RECOMENDATIONS Based on the laboratory analytical data, petroleum-related compounds were detected in the indoor air of the stadium above their respective VISLs; however, the building was under construction at the time and construction supplies may have contributed to these petroleum- High Point Multi Stadium - Indoor Air and Soil Gas Sampling Report High Point, Guilford County, North Carolina Brownfields Project Number 21047-17-041 ECS Project No. 49-5318A June 11, 2019   5 related compounds in indoor air. TCE was detected in one indoor air sample above its non- residential VISL. Construction supplies may have also contributed to TCE in indoor air. Although VOCs were detected in the sub-slab soil gas samples, their concentrations did not exceed their respective VISLs. ECS recommends sampling the indoor air in the stadium after construction is completed and construction supplies are no longer present or being used and when openings between spaces have been closed with doors, windows or other similar appurtenances. 5.0 QA/QC The Summa canisters were batch certified for the soil gas samples and individually certified for indoor air samples. Helium concentrations did not exceed five percent (5%) helium above the shroud concentrations of helium in the helium leak tests for sub-slab samples. During the sampling process, the sample train was closed when the canister vacuum decreased to approximately 4 to 5 inches of mercury (in-Hg). As indicated previously, ECS resampled at sample location A-3 and A-5 after it discovered that there was no longer vacuum in the canisters at these locations during the initial sampling event. ECS documented the vacuum readings indicated on each canister at initiation and termination of sampling. These reading are included in the field notes included as Appendix C.
