North Carolina Department of Environmental Quality Division of Waste Management UST Section Attn: Mr. Scott Ryals 1646 Mail Service Center Raleigh, NC 27699-1646 Re: Letter Report Rural Hall Shell, Inc. 7890 Broad Street, Rural Hall, NC 27045 Incident Number: 30656 Risk Classification: Low CATLIN Project No. 222159 Dear Mr. Ryals,
CATLIN Engineers and Scientists (CATLIN) is pleased to provide you with this letter report documenting field activities performed in general accordance with CATLIN proposal number 222159.3P, prepared January 12, 2023. Services were authorized by the North Carolina Environmental Quality (NCDEQ) Task Authorization (TA) #03, accepted January 13, 2023, and Contract Number N122019D. The approved scope of services for this Task Authorization included:
• Gauge and sample one (1) on-site monitoring well (MW-1);
• Analyze the groundwater sample from MW-1 and one trip blank per Standard Method (SM) 6200B plus ethylene dibromide (EDB), methyl tert-butyl ether (MTBE), and diisopropyl ether (DIPE); and
• Prepare a letter report documenting the findings. The Rural Hall Shell, Inc. site is located at 7890 Broad Street, Rural Hall, Forsyth County, NC
(See Figure 1 in Attachment A). CATLIN conducted field activities on February 1, 2023 in accordance with the approved TA and the pre-prepared Health and Safety Plan (HASP). Potential hazards were evaluated before beginning field work and documented on an electronic Job Hazard Analysis (JHA) form, provided in Attachment B. Photographs from the site activities are presented in Attachment C. While light non-aqueous phase liquid (LNAPL, aka free product) was not measured in MW-1, there appeared to be potential globules of product in the first bailer obtained from the top of the water column. The water exhibited a strong hydrocarbon odor.

Groundwater Gauging
On February 1, 2023, CATLIN personnel gauged monitoring well MW-1 using an electronic groundwater interface probe. Gauging data was recorded on an electronic field data sheet using a tablet device. A copy of the field data sheet is included in Attachment B. Gauging procedures
were performed in general accordance with NCDEQ Guidelines and Environmental Protection Agency (EPA) Region 4 Operating Procedures. Depth to water was 19.67 feet below top of casing. Gauging results are presented in Table 1 (Attachment D) and the location of monitoring well MW-1 is illustrated on Figure 2 (Attachment A). Groundwater Sampling Following gauging, MW-1 was sampled in accordance with NCDEQ Guidelines and EPA Region 4 Operating Procedures. Prior to obtaining a representative groundwater sample, the well was purged by removing a minimum of three well volumes. Groundwater field parameter data were measured at one-minute intervals using an In-Situ Aqua TROLL 600 Multiparameter Sonde (Aqua TROLL). The Aqua TROLL measured specific conductivity, pH, oxidation reduction-potential
(ORP), dissolved oxygen, and temperature, which were recorded utilizing the VuSitu mobile application (version 1.17.12). Groundwater parameter data were transferred from the VuSitu mobile application to the electronic groundwater sampling forms. A copy of the groundwater
sampling form is available in Attachment B. After a minimum of three well volumes were removed (or the well was bailed dry), groundwater samples were collected from the wells and poured into appropriate laboratory-provided, pre-preserved glassware, labeled, and placed on ice in an insulated cooler. A laboratory-provided trip blank was maintained in the cooler for the duration of the event. The groundwater sample and laboratory-provided trip blank were submitted to Con-Test Analytical Laboratory (Certification NC 652 and NC-DW 25703) in East Longmeadow, Massachusetts, under proper chain of custody (COC) protocol and analyzed per SM 6200B (including EDB, MTBE, and DIPE). The laboratory analytical data and COC are included in
Attachment E. Groundwater Sample Results
On February 1, 2023, a sample was collected from monitoring well MW-1. The sample was submitted for analysis via SM 6200B (including EDB, MTBE, and DIPE). Laboratory analysis
revealed that no analyte concentrations were detected above their Gross Contaminant Levels (GCL). Analytical results reported the following targeted analytes in the MW-1 sample at concentrations greater than those established in Title 15A of the North Carolina Administrative Code, Subchapter 2L, Section .0202 Groundwater Quality Standards (2L GWQS): benzene, n-butylbenzene, ethylbenzene, isopropylbenzene, p-isopropyltoluene, MTBE, naphthalene, n-propylbenzene, styrene, toluene, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene, and total xylenes.
One laboratory-provided trip blank was submitted for analysis per SM 6200B (including EDB, MTBE, and DIPE). No targeted analytes were detected in the sample.

Laboratory analytical results are summarized on Figure 2 (Attachment A) and in Table 2 (Attachment D). A copy of the complete laboratory report and chain of custody documentation is
presented in Attachment E.
Recommendations
CATLIN recommends conducting a semi-annual sampling event. If no measurable LNAPL is encountered and groundwater concentrations are below GCL, the site may be closed after filing a Notice of Residual Petroleum.
CATLIN Engineers and Scientists will proceed upon notification of your approval. Should you have any questions or require additional information, please contact us at [phone].

*QC result is outside of established limits.
Wide recovery limits established for difficult compound.
Wide RPD limits established for difficult compound.
#Data exceeded client recommended or regulatory level
Percent recoveries and relative percent differences (RPDs) are determined by the software using values in the
calculation which have not been rounded.
No results have been blank subtracted unless specified in the case narrative section.
FLAG/QUALIFIER SUMMARY
Detected but below the Reporting Limit (lowest calibration standard); therefore, result is an estimated
concentration (CLP J-Flag).
J
Laboratory fortified blank/laboratory control sample recovery and/or duplicate recovery are outside of control
limits. Reported value for this compound is likely to be biased on the high side.
L-06
Either laboratory fortified blank/laboratory control sample or duplicate recovery is outside of control limits, but
the other is within limits. RPD between the two LFB/LCS results is within method specified criteria.
L-07
Elevated reporting limit due to high concentration of target compounds.RL-11
