EXECUTIVE SUMMARY SUMMIT was retained by a perspective purchaser to complete due diligence studies of the subject property located at 9920 Mallard Glen Drive, Charlotte, North Carolina. The site parcel at that time was identified by Mecklenburg Parcel ID: 02903112. A recent recombination plat was recorded and the subject property is now a portion of Mecklenburg County Parcel ID: 02903122. The subject property was observed to contain a single-family home constructed in 1956. One water supply well and one 500-gallon heating oil UST was observed in the October 2019 site reconnaissance. The water supply well was out of service and the home appeared vacant. The water well was subsequently abandoned prior to UST closure in preparation for future site development. The residential home was demolished during the completion of this IAA. A limited assessment of the UST was completed to determine if a release had occurred. Multiple soil borings were completed adjacent to the UST. One soil sample submitted for analysis documented petroleum impacts with Naphthalene above the MSCCs Soil to Groundwater at 5 feet below ground surface. A release notification was submitted to NCDEQ in April 2020. In December 2020 UST closure by removal and Initial Abatement Actions were conducted. 275- gallons of petroleum contact liquids was removed from the tank prior to closure. The UST was removed form ground utilizing an excavator and secured for transport and disposal by T K Tank Services of Sumter, SC. Visual staining and petroleum odors were noted in the base of the excavation. 2 feet of soils from all sidewalls and 4 feet of soils below the UST was excavated from around the UST and transported off -site for disposal by T K Tanks Services. Excavation was terminated when field screening indicated minimal VOC detections. A total of 6 tons of soil was transported offsite in the Initial Abetment Action in December 2020. Soil samples were collected from the sidewalls at approximately 5 feet below ground and one soil sample was collected from the base of the excavation at 8 feet below ground surface. Samples were submitted for VOC, SVOC and EPH/VPH analysis in accordance with DEQ guidance. Results reported Benzo (a)pyrene above Soil to Groundwater MSCCs in the western and southern sidewalls. Results reported 2- C:Aplowery\Documents\2-Projects\5778.E0778 The Heritage at UNCC -UST ClosureAlnitial Abatement Action\5778.E0778 IAA with Site Closure 3 Request.doc Initial Abatement Action Report SUMMIT Project No. 5778.E0778 9920 Mallard Glen Drive, Charlotte, North Carolina May 10, 2021 Mythylnaphthalene, Phenanthrene, C9-C18 Alphatics and C9-C22 Aromatics above Soil to Groundwater MSCCs in the base of excavation. Additionally, C9-C22 aromatics was identified in the northern and western sidewalls above the Soil to Groundwater MSCCs. Based on the results, additional abatement was recommended. In February 2021, SUMMIT directed the client provided grading contractor to over excavate the UST basin in an effort to fully remove soil impacts. An additional 22 tons of soil was removed from the initial excavation sidewalls and base and transported to Republic Landfill for disposal. The western sidewall was excavated an additional 5 feet, northern and southern sidewalls an additional 4 feet and the base was lowered an additional 3 feet. Confirmation soil samples were collected from the western wall and base of excavation. Due to a sampling error, the northern and southern sidewalls were not resampled following abatement actions. Results of the collected confirmation samples from the western sidewall and base reported no impacts above regulatory concentrations remained. On April 26, 2021, the northern and southern sidewalls were re -sampled for confirmation of full removal of impacts. These confirmation samples were analyzed for the compounds that originally reported to exceed the corresponding Soil to Groundwater MSCCs. Results of the collected confirmation samples from the northern and southern sidewalls reported no impacts above regulatory concentrations remained. No water supply wells are located within 150 feet of the UST basin. Groundwater was not encountered during IAA. Bedrock was not encountered in the UST basin during IAA. Based on the Initial Abatement Actions taken and the results of confirmation sampling, SUMMIT requests closure with No Further Action at this time.

Release Information SUMMIT personnel visited the site on November 8, 2019. The Heating Oil UST was observed to be located near the southeast of the home near the driveway. Utilizing a soil probe, SUMMIT personnel determined the size of the UST to be approximately 8 feet in length and 4 feet in diameter. SUMMIT completed five (5) geo-probe borings around the UST. Boring SB-1 and SB-2 were located at the approximate end of the UST. SB-3 was located on the downgradient side of the UST. SB-4 and SB-5 were offset away from the UST. Each soil boring was extended to 10 feet below ground surface (bgs). Typical brown -tan sandy Silts were encountered in the soil borings. SB-2 exhibited petroleum soil staining, odors and positive detections of field screening equipment from 3 to 6 ff bgs. Soil sample SS-1 was collected from 5 ft bgs and soil sample SS-2 collected from 7 ft bgs. The collection of SS-1 and SS-2 will help define the vertical extent of impacts. SB-4 and SB-5 were spaced out in 2 directions from SB-2 in order to help define the lateral extent of impacts. SB-4 did not display indicators of petroleum impact. SB-5 detected slight petroleum staining and odors at approximately 5 ft bgs. SS-3 was collected from SB-5 at 5 ft bgs. Typical brown -tan sandy Silts were encountered in the soil borings. Soil samples collected were bottled for submittal to a North Carolina certified laboratory for analysis of BTEX, Naphthalene and Poly -cyclic Aromatic Hydrocarbons (PAHs). It should be noted that groundwater was not encountered in any boring. On December 8, 2020 SUMMIT directed the removal of the UST and excavation of impacted soils by T K Tank Services of Sumter, SC. Soil staining and corrosion pinholes on the tank ends were observed during tank removal. 6 tons of petroleum impacted soil was excavated from the base of excavation and sidewalls into a truck for transport and disposal at T K Services treatment facility. Closure samples were collected from the 4 sidewalls and base of excavation. Results of the closure sampling reported elevated EPH/VPH remained in the base and western side wall of the excavation. On February 24, 2021, the grading contractor excavated additional base soils and from sidewalls for transport and disposal by Centurion at Republic Landfill. An additional 22 tons were removed and manifested to Republic CMS Landfill. Closure samples SB-6 and SB-7 were collected to confirm clean closure from the western sidewall and base of excavation. The northern and southern sidewalls were over excavated however samples were not collected from these locations C:Aplowery\Documents\2-Projects\5778.E0778 The Heritage at UNCC -UST ClosureAlnitial Abatement Action\5778.E0778 IAA with Site Closure 6 Request.doc Initial Abatement Action Report 9920 Mallard Glen Drive, Charlotte, North Carolina SUMMIT Project No. 5778.E0778 May 10, 2021 at that time. On April 26, 2021 SB-8 and SB-9 were collected from the northern and southern sidewalls. SB-8 and SB-9 were analyzed for compounds the previously exceeded Soil to Groundwater MSCCs. C.S. Site Characteristics The United States Geological Survey (USGS) "Harrisburg" topographic quadrangle map was reviewed for this report. According to the contour lines on the topographic maps, the elevation of the subject property ranges from 700 feet above Mean Sea Level (MSL) to 680. The contour lines indicate the general direction of downward slope is to the south towards Mallard Creek. This site contains the soil types: Wilkes soil series: The Wilkes series consists of shallow, well drained soils with moderately slow to slow permeability. They formed in residuum weathered from intermediate and mafic crystalline rocks on uplands in the Piedmont. Near the type location, mean annual air temperature is 59 degrees F., and mean annual precipitation is 45 inches. Slopes range from 4 to 60 percent. The surface cover of the UST basin was bare soil.

Excavation Tank removal and abatement actions were initiated on December 8, 2020. T& K Tank Services mobilized to the subject property with a excavator, pump truck and dump truck. The UST fill port was utilized to remove liquids from the tank prior to removal. 257-gallon of liquid petroleum and petroleum contact water were purged from the tank. Excavation of the tank started with the exposing the top of the steel 500-gallon UST. Soils from the sides of the UST were then removed, exposing the sides of the UST. The UST was then hooked to a chain and pulled from the UST basin. Corrosion pinholes were noted along the base and ends of the UST. Soil staining along the base and eastern sidewalls was observed. Soils of the basin consisted of hard silts and clays. SUMMIT directed the excavation of visually impacted soils from the basin. Field screening utilizing a rented calibrated Mini -Rae 3000 PID was conducted on the remaining exposed sidewalls and base of the UST basin. Excavation continued to until field screening results indicated an absence of VOC compounds. A total of 6 Tons of soil was removed for the UST basin and transported to a treatment facility operated by T K Tank Services in Sumter, SC. The UST was crushed and recycled by T K Tank Services. The initial excavation measured 8' x 12'x 8' (LxWxD). Post excavation sampling indicated impacted soils remained following the initial abatement/closure activities. On February 24, 2021 SUMMIT directed a grading contractor provided by the site developer to over excavate the base and sidewall of the UST basin that reported elevated EPH/VPH. The base of the excavation was excavated to an approximate depth of 12 feet below ground surface. The western sidewall was excavated an additional 5 feet. The northern and southern sidewalls were excavated an additional 4 feet. The eastern sidewall was excavated an additional 2 feet. A total of 22 tons was transported to Republic CMS Landfill for disposal by Centurion. The resulting excavation following abatement was approximately 15' x 20'x 12' (LxWxD). J.3. Post Excavation Sampling SUMMIT collected four (4) soil samples from the sidewalls of the tank basin and one (1) soil sample from the base of the excavation on December 8, 2020. The sidewall samples were C:Aplowery\Documents\2-Projects\5778.E0778 The Heritage at UNCC -UST ClosureAlnitial Abatement Action\5778.E0778 IAA with Site Closure 9 Request.doc Initial Abatement Action Report SUMMIT Project No. 5778.E0778 9920 Mallard Glen Drive, Charlotte, North Carolina May 10, 2021 collected at approximately 5 feet from the top of the excavation. The bottom sample was collected from the center of the tank basin. Samples SB-1, 2, 3, 4 and 5 were collected from the resulting excavation. Figure 3A and 3B documents the location of the samples collected. Samples were submitted for VOC, SVOC, EPH and VPH per DEQ requirements. Sample results indicated elevated EPH and VPH remained in the northern, southern, western sidewalls and base of excavation. On February 24, 2021 SUMMIT directed a grading contractor provided by the site developer to over excavate the base and sidewall of the UST basin that reported elevated EPH/VPH. The base of the excavation was excavated to an approximate depth of 12 feet below ground surface. The western sidewall was excavated an additional 5 feet. The northern and southern sidewalls were excavated an additional 4 feet. The eastern sidewall was excavated an additional 2 feet. A total of 22 tons was transported to Republic CMS Landfill for disposal by Centurion. The resulting excavation following abatement was approximately 15' x 20'x 12' (LxWxD). Samples SB-6 and SB-7 were collected from the base of excavation and western side wall following the additional removal. Samples were not collected at this time from the northern and southern sidewalls due to collection error. On April 26, 2021 SB-8 and SB-9 were collected from the northern and southern sidewalls and analyzed for the compounds that previously exceeded the Soil to Groundwater MSCCs. The collected confirmation samples from base of excavation and sidewalls indicated successful removal of impacted soils from these locations. J.4 Soil Investigation New, clean disposable latex gloves were used for the collection of each soil or groundwater sample. Samples collected for laboratory analyses were placed in laboratory -supplied containers with the sampler's name, time and date the sample was collected, and laboratory analyses to be performed. The samples were packed on ice and taken to Pace Analytical Services, LLC in Columbia, South Carolina. For a drawing detailing the locations of the soil samples, please refer to Figure 3.0 in the appendices. Groundwater was not encountered in the excavation. The samples were grab samples. Standard chain -of -custody procedures were followed. C:Aplowery\Documents\2-Projects\5778.E0778 The Heritage at UNCC -UST ClosureAlnitial Abatement Action\5778.E0778 IAA with Site Closure 10 Request.doc Initial Abatement Action Report SUMMIT Project No. 5778.E0778 9920 Mallard Glen Drive, Charlotte, North Carolina May 10, 2021 Field screening was based on visual and olfactory observations. In addition, soil samples were taken from the excavation and were analyzed onsite using an calibrated Mini Rae 3000 handheld PID w/ VOC Measurement. Prior to each analysis, the PID was allowed to equilibrate to the area temperature and ambient air conditions. J.S. Disposal Approximately 6 tons of contaminated soils were removed from the site on December 8, 2020 and taken to T K Tank Services in Sumter, SC for treatment at the permitted facility. Approximately 22 tons of contaminated soils were removed from the site on February 22, 2021 and taken to Republic Service, Inc. in Concord, NC. K. CONCLUSIONS Due diligence studies conducted for the property identified a petroleum release associated with the home heating oil tank at 9920 Mallard Glen Drive, Charlotte, North Carolina. The first abatement action occurred in December 2020 during UST closure, with a total of 6-tons of soil removed from the UST basin for disposal at a treatment facility in Sumter, SC. EPH/VPH exceedances remained and a second abatement action was conducted in February 2021, with a removal of an additional 22-tons of soil. Confirmation sampling conducted confirms that the sidewalls and base of excavation are below regulatory levels. No free product was encountered. Groundwater was not encountered. Competent bedrock was not encountered. SUMMIT concludes that the Abatement Actions and UST closure were successful.

(SUMMIT) has completed a limited assessment of a Home Heating Oil (HHO) underground storage tank (UST) at 9920 Mallard Glenb Drive, Mecklenburg County, North Carolina. SUMMIT personnel conducted the site field work on November 8, 2019. The site is irregular in shape and was noted to be comprised of one (1) parcel totaling approximately 1.49 acres in area. The site is developed with one (1) single family home and associated outbuildings. The residential structure is approximately a 1,2464 SF home, constructed in 1956. SUMMIT personnel visited the site on November 8, 2019. The HHO UST was observed to be located near the southeast of the home near the driveway. Utilizing a soil probe, SUMMIT personnel determined the size of the UST to be approximately 8 feet in length and 4 feet in diameter. SUMMIT completed five (5) geo-probe borings around the UST. Boring SB-1 and SB-2 were located at the approximate end of the UST. SB-3 was located on the downgradient side of the UST. SB-4 and SB- 5 were offset away from the UST. Each soil boring was extended to 10 feet below ground surface (bgs). Typical brown -tan sandy Silts were encountered in the soil borings. SB-2 exhibited petroleum soil staining, odors and positive detections of field screening equipment from 3 to 6 ff bgs. Soil sample SS-1 was collected from 5 ft bgs and soil sample SS-2 collected from 7 ft bgs. The collection of SS-1 and SS-2 will help define the vertical extent of impacts. SB-4 and SB-5 were spaced out in 2 directions from SB-2 in order to help define the lateral extent of impacts. SB-4 did not display indicators of petroleum impact. SB-5 detected slight petroleum staining and odors at approximately 5 ft bgs. SS-3 was collected from SB-5 at 5 ft bgs. Typical brown -tan sandy Silts were encountered in the soil borings. Soil samples collected were bottled for submittal to a North Carolina certified The Heritage at UNCC SUMMIT Project No. 5778.500 Charlotte, North Carolina November 25, 2019 laboratory for analysis of BTEX, Naphthalene and Poly -cyclic Aromatic Hydrocarbons (PAHs). (It should be noted that groundwater was not encountered) Laboratory results were compared to North Carolina Department of Environmental Quality (NCDEQ) Maximum Soil Contaminant Concentrations (MSCCs). Table 1.0 attached to this document summarizes the detections. As indicated on the attached summary table, sample SS-1, collected at 5 ft bgs adjacent to the northern tank end, detected the presence of petroleum compound Naphthalene above the established Soil to Groundwater MSCC. No detections were reported for SS- 2 or SS-3. Based on the results of our inspection, SUMMIT concludes that the HHO USTs has released petroleum products into the surrounding soils. Per NCDEQ regulations, the UST owner is required to submit a 24-Hour Release notification (Form UST-6 1). A copy of this form is attached to this letter and a copy can be obtained at https://deq.nc.gov/about/divisions/waste-management/ust/forfns. A copy of this limited assessment should be submitted along with the UST 61 to the NCDEQ Mooresville Regional Office. SUMMIT recommends the removal and proper closure of the UST in accordance with NCDEQ UST guidelines. Based on the detections of concentrations above the established Residential MSCCs, the Notice of Residual Petroleum (NRP) would be required if soils are to remain in place following UST removal. Soil over -excavation would be required in order to avoid an NRP and receive a No Further Action status from NCDEQ. This letter includes a description of the methodology of our investigation and a summary of our findings and conclusions. If you have any questions regarding our assessment of the subject property, our conclusions or recommendations, please do not hesitate to call us at (704) 504-1717.

Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping (e.g., a release from a suction pump or from components located above the shear valve) Submersible Turbine Pump (STP) Area includes the submersible turbine pump head (typically located in the tank sump), the line leak detector, and the piping that connects the submersible turbine pump to the tank Delivery Problem: identifies releases that occurred during product delivery to the tank. (Typical causes associated with this source are spills and overfills.)

The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace") Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or discussed below.

VOCs by GC/MS The laboratory control sample duplicate (LCSD) for analytical batch 76782 exceeded acceptance criteria for : Methylcyclohexane and tetrachloroethene. These analytes were biased high and were not detected in the samples affected. VPH Surrogate recovery for the following samples was outside control limits: VL08062-002, VL08062-003, VL08062-005. Evidence of matrix interference is present; therefore, re -extraction and/or re -analysis was not performed. SVOCs by GC/MS The following sample was diluted due to appearance or color: VL08062-001. The LOQ has been elevated to reflect the dilution. Sample -005 has been analyzed at a 10X dilution due to large detections of the target compounds. This large dilution caused a surrogate to recover outside of method criteria. No corrective action is required as it is known that dilutions of 5X and greater may impact surrogate recoveries.

Lot Number: WC01007 This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary following this Case Narrative. The sample receiving date is documented in the header information associated with each sample. All results listed in this report relate only to the samples that are contained within this report. Sample receipt, sample analysis, and data review have been performed in accordance with the most current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace") Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or discussed below. Where applicable, all soil sample analysis are reported on a dry weight basis unless flagged with a "W" qualifier If you have any questions regarding this report please contact the Pace Project Manager listed on the cover page. SVOCs by GC/MS The following samples were diluted due to appearance or color: WC01007-001, WC01007-002. The LOQ has been elevated to reflect the dilution. The method blank associated with batch 84430 yielded a "J" value detection for Di-n-butyl phthalate. No corrective action is required as this is an estimated value recovered below the LOQ. The LCS associated with this batch recovered Butyl benzyl phthalate above method criteria. No corrective action is required as all associated samples are non -detect for this compound.

Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to Report Spam. Trudy, Good afternoon. We submitted the attached release notification last May for the heating oil tank at 9920 Mallard Glen Drive. I cant seem to locate a incident # for this release on laserfiche or DWM GIS. Not sure this one got logged in as I initially sent this over to Dan. Either way, our client finely moved forward with closure earlier this year and we need to submit the documentation for closure. Soil was excavated and we were able to get clean margins on all 4 sidewalls and base. Looking at the updated Corrective Action report formats, it looks like the Initial Abatement Action report is no longer presented. Would we be going the format for Soil Cleanup with Closure Request (#12)? Since this appears new I wanted to reach out and get your advise on how to proceed. Could you point me to a recent approved heating oil tank closure site that I can look up and review to ensure I cover all my bases. I will have a few more of these to produce so I want to be sure I get you exactly what you are needing. Feel free to call me on my cell at 803-230-5087 anytime.
