(WR) has prepared this Stormwater Pipe Corridor Investigation Report to document activities that took place on August 24, 2018. Background The property formerly identified as 609 West South Street is transected from north to south by a sub-surface, 60-inch diameter stormwater pipe (Figure 1). The pipe is constructed of corrugated aluminum and discharges stormwater, collected from properties to the north, to a tributary of Rocky Branch along the southern property boundary of the subject site. The stormwater pipe is in disrepair and is planned to be replaced in November 2018, prior to site redevelopment activities. Unsuitable fill material surrounding the stormwater pipe was not removed during grading activities that took place on the subject properties between December 2016 and September 2017. Soils surrounding the stormwater pipe were deemed unsuitable for construction by a geotechnical engineering firm due to the presence of fill and/or rubble material. Due to the presence of unsuitable materials surrounding the stormwater pipe and the possibility of offsite disposal of said material, WR wrote a Stormwater Pipe Replacement Investigation Work Plan, dated July 25, 2018, outlining a soil and groundwater sampling plan along the stormwater pipe corridor. The aforementioned work plan for this phase of site work was approved by the North Carolina Brownfields Program in an email on July 31, 2018. Soil Sampling Procedures WR mobilized to the subject property on August 24, 2018 to advance eight soil borings along the stormwater pipe using a direct-push Geoprobe drilling machine. Soil samples were collected with 60-inch long, new macrocore liners and decontaminated tooling. Collected soil samples were immediately placed in laboratory supplied bottleware following the opening of the macrocore liner by the onsite geologist. Collected soil samples were then placed WithersRavenel Our People.

Juliet, TN (ESC) for analysis by the following methods: • Volatile Organic Compounds (VOCS) by EPA Method 8260B, Semi-VOCs (SVOCs) by EPA Method 8270D, and RCRA-8 Metals by 6010D / 7471B. Soil samples were collected from the following depth intervals*: • SWP-1**: 1 to 5 feet and 15 to 20 feet below ground surface; • SWP-2**: 1 to 5 feet and 15 to 20 feet below ground surface; • SWP-3: 1 to 5 feet and 10 to 15 feet below ground surface; • SWP-4: 1 to 5 feet and 10 to 15 feet below ground surface; • SWP-5: 1 to 5 feet and 12 to 15 feet below ground surface; • SWP-6: 1 to 5 feet and 10 to 15 feet below ground surface; • SWP-7: 2 to 5 feet and 12 to 14 feet below ground surface; and • SWP-8: 1 to 5 feet and 10 to 15 feet below ground surface. Notes: * Soil collection intervals were increased with respect to the work plan due to low macrocore recovery. ** Borings SWP-1 and SWP-2 were advanced in the undisturbed / ungraded portion of the site located along the southern property line. Following sample collection, the remaining soils in the liner were classified and placed in zip-lock baggies for field screening with a field calibrated MiniRAE 3000 photo-ionization detector (PID). The field meter readings are shown on the boring logs which are included in the Appendix. Sampling locations were recorded with a sub-meter GPS device. Sampling locations are illustrated on Figure 1 and latitude / longitude coordinates are provided on Table 1. Groundwater and Stormwater Sampling Procedures Following the advancement of soil borings SWP-4 and SWP-7, 1-inch diameter well screen was installed in each boring to facilitate the collection of a groundwater sample from each location. The temporary wells were identified as TWSWP-4 and TWSWP-7. The following table summarize temporary well information. Temporary Well ID Total Depth (ft) Groundwater Depth Below Ground Surface (ft) TWSWP-4 15 9.85 TWSWP-7 13 8.60 Each temporary well was purged with a peristaltic pump and dedicated polyethylene tubing for a minimum of one hour to remove fine sediments from the water column.

Groundwater samples were decanted from the tubing and placed in laboratory supplied bottleware, immediately placed in a cooler containing ice, and shipped under proper chain of custody procedures to ESC Lab Sciences, in Mt. Juliet, TN (ESC). Groundwater samples were laboratory analyzed by the following methods: • VOCS by EPA Method 8260B, SVOCs by EPA Method 8270D, and RCRA-8 Metals by 6010D / 7470A. Following sample collection, each temporary well was properly abandoned by removing the well screen and filling the boring void with bentonite. WR also collected a sample of the stormwater exiting the pipe outfall near the southern property line. At the time of the sample approximately four inches of water was flowing through the pipe. The sample was collected by filling the laboratory supplied bottleware with the stormwater exiting the pipe. Following sample collection, the sample was immediately placed in a cooler containing ice and shipped under property chain of custody procedures to ESC Lab Sciences, in Mt. Juliet, TN (ESC). The outfall sample was laboratory analyzed by the following method: • VOCS by EPA Method 8260B. Sampling locations are illustrated on Figure 1 and latitude / longitude coordinates are provided on Table 1. Soil Laboratory Analytical Results The laboratory analytical results are summarized in Table 2 and the laboratory analytical report is included in the Appendix. Boring locations are illustrated on Figure 1. RCRA-8 Metals: Arsenic, barium, chromium (total), cadmium, lead, and mercury were detected at concentrations above the laboratory method detection limit (MDL) in one or more of the collected soil samples. Arsenic and chromium were detected in one or more of the soil samples at concentrations that exceeded the Residential and / or the Industrial / Commercial Health Preliminary Soil Remediation Goals (PSRGs) from February 2018. Though these concentrations exceeded published PSRGs, their concentrations are comparable to typical background concentrations according to the U.S. Geological Survey Professional (USGS) Paper 1648. Arsenic and chromium concentration distribution figures from USGS Paper 1648 are provided in the appendix. WithersRavenel Our People.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. 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. MDL (dry)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. 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. 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. J7 Surrogate recovery cannot be used for control limit evaluation due to dilution. 1 Cp 2Tc 3Ss 4Cn 5Sr 6Qc 7Gl 8Al 9Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Withers & Ravenel Eng. - Standard 02170761 L1020964 09/11/18 17:24 100 of 105 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Withers & Ravenel Eng. - Standard 02170761 L1020964 09/11/18 22:29 100 of 105 ONE LAB.
