This Phase II investigation consisted of running geophysical surveys and testing soil around USTs for petroleum constituents. The property is located on the northern edge of a bedrock ridge. Bedrock is exposed in several areas of the property. Bedrock at the Subject site is the Blowing Rock Gneiss, an augen gneiss. The Phase II scope of work included completing geophysical surveys at the property to investigate the potential for underground storage tanks followed by soil sampling to assess soil quality and estimate the volume of potentially contaminated soil at the site. The Subject property contains one 10,000 gallon heating oil UST (registered UST) that is in use. This UST is registered with the NCDEQ and has a Facility ID number of 29682. The tank is listed in the NCDEQ database as being installed in 1964. The old medical building was constructed in the mid-1950s. The geophysical survey was conducted to look for a possible UST that would have been used between 1955 and 1964. 2.0 Scope of Work 2.1 Geophysical Surveys Seramur & Associates completed geophysical surveys around the old medical clinic building to look for underground storage tanks. Magnetometer surveys were completed with a MF-1 Fluxgate magnetometer. The MF-1 Fluxgate magnetometer is designed to measure changes in the earth’s magnetic field associated with larger objects. It does not respond to smaller objects such as nails or wire, but responds well to manholes, steel pipe, buried drums and tanks. The sensitivity level is well suited for detecting buried USTs at commercial and industrial facilities. Ground Penetrating Radar (GPR) was used to survey areas where magnetic anomalies were detected. GPR data was collected using Geophysical Survey Systems, Inc. 400 MHz antenna and a SIR-3000 Single Channel Data Acquisition System with a calibrated survey wheel. The GPR data was downloaded and saved onto a computer. The GPR data processing included adjusting time zero, completing a background removal and adjusting the time variable gain to enhance deep reflections. 2.3 Soil Sampling and Analyses On June 13, 2016, Geonetics Corporation, Dba: Techdrill mobilized to the site to drill soil test borings and collect soil samples. Soil borings were drilled around the registered UST and the probable UST identified by the geophysical surveys (Figures 2 and 3). Our project design called for collecting a soil sample from each boring at or below the depth of the bottom of the USTs. A track-mounted rotary drilling rig with hollow-stem augers was used to drill the soil borings. Drilling tools were decontaminated between each soil boring. The drilling tools were cleaned with a hot-water pressure wash. The cutter head was decontaminated by washing with non- Phase II Site Assessment Report July 11, 2016 Blowing Rock Hospital, Blowing Rock, NC Page 4 phosphate detergent, rinsed with de-ionized water, rinsed with isopropyl alcohol and a final rinse with de-ionized water. A new pair of Nitrile gloves was worn while collecting each soil sample. A representative portion of each soil sample was placed in a zip lock bag and allowed to sit for a period of time. A calibrated Photoionization detector was used to screen the headspace in each bag and the concentration of volatile petroleum vapors measured by the PID was recorded. The texture and type of soil material for each sample was recorded. Table 1 lists the soil boring data including sample depth, PID reading, soil texture and type for each sample. A 5-gram terra core soil sampler was used to place the soil samples in containers prepared and supplied by REDLAB, LLC. The containers were labeled and immediately placed on ice in a cooler. Chain of Custody (COC) records were completed to document site information and sample collection data. COC records accompanied the samples from the time they were collected until they were delivered to REDLAB, LLC in Wilmington, North Carolina. The samples were shipped overnight to the laboratory via FedEx. REDLAB, LLC analyzed the soil samples for petroleum constituents by Ultra-Violet Fluorescence using a QED HC-1 analyzer. The laboratory reports and chain of custody records are included in Appendix B. 3.0 Results of Investigation 3.1 Geophysical Surveys Magnetometer anomalies were detected around the old medical building. Many of these were limited in size and the GPR did not image reflections indicative of a UST at most of these magnetic anomalies. A large magnetic anomaly was identified north of the medical building. The GPR imaged a large reflector across the magnetic anomaly. The reflector is 20.5 feet in length and has the characteristics of a buried tank. It appears to be oriented parallel to the building. This anomaly is likely a UST (probable UST) that was used when the medical clinic was built in the 1950s. We showed Mr. Brett Reece, Plant Operations Manager the location of the probable UST. He went back to his office and looked through some old photographs. One photograph of the property shows a possible pipe sticking up out of the ground in the general vicinity of the suspected tank. 3.2 Soil Borings, Sampling and Laboratory Results Soil Sampling at the Registered UST Soil material at the Blowing Rock Hospital property is primarily a sandy silt. Soil borings B-1 through B-3 were drilled around the registered UST located on the south side of the hospital (Figure 2). This UST is oriented north-south and Boring B-1 was drilled off of the the south end of the UST. Petroleum odors were noted in soil sample S-4 collected from a depth of 13.5 to 15 feet in Boring B-1. This boring was advanced to a depth of 25 feet in order to assess the vertical extent of petroleum constituents in the soil around this UST. Soil Boring B-2 was drilled 16 feet south of boring B-1 to assess the horizontal extent of soil contamination to the south. Soil sample S-9 was collected at a depth of 8.5 to 10 feet in boring Phase II Site Assessment Report July 11, 2016 Blowing Rock Hospital, Blowing Rock, NC Page 5 B-2. Auger refusal (interpreted as bedrock) was encountered in boring B-2 at a depth of 13 feet. It was not possible to collect a deeper soil sample from this location. Soil Boring B-3 was drilled on the west side of the UST to assess the horizontal extent of soil contamination west of the UST. Soil sample S-12 was collected from boring B-3 at a depth of 13.5 to 15 feet. Soil samples S-9 and S-12 were shipped to REDLAB, LLC for analysis. Buried utilities between the tank and the hospital building prevented a soil boring on the north side of the registered UST. The East side of the UST is adjacent to the boiler room wall. It was not possible to drill a soil boring between the tank and the boiler room wall. Groundwater Sampling at the Registered UST The water table was encountered at a depth of 11.09 feet in boring B-1. A temporary monitoring well was installed in Boring B-1. Prior to sampling, the monitoring well was purged to bring fresh formation water into the well by bailing at least three well casing volumes of water. The groundwater sample was collected from the monitoring well with a disposable bailer and polypropylene twine. A new pair of disposable nitrile gloves was worn while sampling the well. The groundwater water sample was placed in containers prepared and supplied by Pace Analytical. The containers were labeled and immediately placed on ice in a cooler. A Chain of Custody (COC) record was completed to document site information and sample collection data. COC records accompanied the samples from the time they were collected until they were shipped to Pace Analytical, in Huntersville, North Carolina. The groundwater sample was analyzed for petroleum constituents using EPA methods 6200B, 625 Acid Extractable/Base Neutral with top ten peaks, and the MADEP VPH and EPH Methods. Soil Sampling at the Probable UST Soil borings B-4 through B-7 were drilled around the probable UST located on the north side of the old medical building (Figure 3). This UST is oriented east-west and Boring B-4 was drilled off of the west end of the UST. Petroleum odors were noted in soil samples S-14 and S-15 collected from depths of 8.5 to 10 feet and 13.5 to 15 feet, respectively. This boring encountered auger refusal (interpreted as bedrock) at a depth of 18 feet. It was not possible to collect a soil sample with the split spoon after auger refusal was encountered. Soil sample S-16 was collected from the auger cuttings between depths of 15 and 18 feet. Soil boring B-5 was drilled west of boring B-4 in order to delineate the horizontal extent of soil contamination to the west. Soil sample S-17 was collected at a depth of 13.5 to 15 feet from boring B-5. Boring B-6 was drilled south of the probable UST. This boring encountered auger refusal or rock in all three attempts to drill on the south side of the UST. Auger refusal was encountered at depths of 2 feet, 9.5 feet and 8.5 feet. The drillers drove the split spoon in the two deeper borings, but they were unable to recover a soil sample. The shallow bedrock south of the probable UST will limit the extent of contaminated soil to the south. Soil boring B-7 was drilled to a depth of 13.5 feet where auger refusal was encountered. No sample was recovered from the attempt to drive a split spoon at a depth of 13.5 feet. Soil sample Phase II Site Assessment Report July 11, 2016 Blowing Rock Hospital, Blowing Rock, NC Page 6 S-19 collected at a depth of 8.5 to 10 feet from boring B-7 was sent to REDLAB, LLC for analysis. Analytical Results Petroleum constituents were detected at concentrations above the NCDEQ action levels in soil sample S-4 collected at a depth of 13.5 to 15 feet in boring B-1. Soil samples S-5 and S-6 collected at depths of 18.5 to 20 feet and 23.5 to 25 feet in boring B-1 did not contain petroleum constituents above 10 ppm. Soil samples S-9 and S-12 collected from borings B-2 and B-3 did not contain petroleum constituents above 10 ppm. Petroleum constituents were detected at concentrations above the NCDEQ action levels in soil samples S-15 and S-16 from boring B-4. Soil sample S-14 collected at a depth of 8.5 to 10 feet did not contain petroleum constituents above 10 ppm. Soil samples S-17 and S-19 collected from borings B-5 and B-7 did not contain petroleum constituents above 10 ppm.

The NCDEQ Groundwater Standard for the C9-C10 Aromatic Hydrocarbon Fraction is 200 ppb. This indicates that groundwater quality around the registered UST has not been significantly affected by petroleum constituents detected in soil sample S-4. Phase II Site Assessment Report July 11, 2016 Blowing Rock Hospital, Blowing Rock, NC Page 7 3.3 Volumes and Extent of Contaminated Soil The area of soil contamination around the registered UST is estimated to be 20 feet by 40 feet (dashed red line on Figure 2). This soil contamination is limited to a depth of 8 to 18 feet. This is an area of about 800 ft2 laterally and 10 feet in thickness. = 20 ft. x 40 ft. x 10 ft. = 8000 cubic feet = 296 cubic yards The area of soil contamination around the probable UST is estimated to be 16 feet by 30 feet (dashed red line on Figure 3). This soil contamination is limited to a depth of about 8 to 18 feet. This is an area of about 480 ft2 laterally and 10 feet in thickness. = 16 ft. x 30 ft. x 10 ft. = 4,800 cubic feet = 178 cubic yards 3.4 Conclusions Contaminated soil was detected at the base of the registered UST on the south side of the hospital building. Soil samples collected between 18 and 25 feet did not contain petroleum constituents above the NCDEQ Action Levels. Petroleum constituents were not detected at/or above the NCDEQ Groundwater Standards in a groundwater sample collected from a temporary monitoring well installed in boring B-1. Soil contamination appears limited around this UST and groundwater contamination was not detected. The registered UST will need to be closed according to NCDEQ requirements. Contaminated soil around the registered UST will need to be excavated and properly disposed. NCDEQ may require a new monitoring well and groundwater sample to confirm the results from the temporary well. Removal of contaminated soil and a clean groundwater sample should allow NCDEQ to close out this release incident. Soil contamination around the probable UST is limited and groundwater was not encountered. This tank is located on the edge of the slope. There is shallow bedrock and it appears that the soil contamination extends down to the top of bedrock at a depth of 18 feet. The probable UST will need to be closed according to NCDEQ requirements. Contaminated soil around this second UST will need to be excavated and properly disposed. Since contaminated soil extends down to the top of bedrock, NCDEQ may require a monitoring well and groundwater sample to assess groundwater quality in the vicinity of the probable UST. Bedrock is shallow around the probable UST north of the clinic building. Cleaning up soil contamination should be possible. If groundwater contamination is present, NCDEQ may require groundwater remediation in order to close out this release. NCDEQ can require that a “Notice of Residual Petroleum” be filed on the deed to the property if these two release incidents are not closed.

The sample was analyzed at dilution. The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. MRL E U J D B N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a “tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported.
