RELEASE INFORMATION AND SITE CHARACTERISTICS 1. Incident Information: The site of the release is located on the shoulder of Ludie Brown Road, Chinquapin, Duplin County, NC (Figure 1). Reportedly, a truck owned by Julio Figueroa had a leaking saddle tank due to a vehicle accident on December 27, 2022. Approximately 100 gallons of diesel fuel was released from the leaking saddle tank onto shoulder of the Ludie Brown Road. Initial abatement activities were conducted by Tarheel Concrete. On January 3, 2023, impacted soil was excavated until soil samples reported concentrations less than the Regulatory Action Level (RAL). On January 4, 2023, a UST-62 Form was submitted to North Carolina Department of Environmental Quality (NCDEQ). A copy of the UST-62 Form is included as Appendix A. A Site Map is included as Figure 2. 2. Historical Information: No historical information is available for the site. 3. Comprehensive Description of the Release: Reportedly, approximately 100 gallons of diesel was released from a saddle tank of a truck involved in a vehicle accident. 4. Description of the Site Characteristics: The spill occurred on the shoulder of Ludie Brown Road approximately 445 feet west of Willie Hatcher Road. The impacted soil from the spill covered an area of approximately 361 square feet to a depth 2 feet below ground surface (bgs). The surrounding area is residential and agricultural. Public water is available to the surrounding area. 5. Summary of Initial Abatement Actions, Assessment Activities, and Corrective Actions: On January 3, 2023, Tarheel Concrete initiated abatement activities by using a track mounted excavator to remove impacted soil. GRI personal supervised excavation activities based on UVF analytical results and field observations. Impacted soil was excavated until the total petroleum hydrocarbon (TPH) gasoline-range organics (GRO) and diesel-range organics (DRO) values were less than the regulatory action levels (RAL). 6. Contaminated Soil and Water Storage/Treatment and/or Disposal: On January 3, 2022, the excavation of 22.37 tons of impacted soil from the spill area was loaded directly into a dump truck and transported to a permitted disposal facility. A soil disposal manifest is included as Appendix B. B. SOURCE INVESTIGATION 1. Investigation Performed To-Date to Determine the Source of the Release: The release was the result of a saddle tank of a truck involved in a vehicle accident. _____________________________________________________________________________________ Prepared by: Geological Resources, Inc.

Soil Excavation and Sampling Based upon onsite mobile laboratory results from January 3, 2022, GRI personnel supervised the excavation of 22.37 tons of soil from area of approximately 361 square feet to a depth 2 feet bgs. During excavation activities, GRI personnel collected soil samples (SS-1-2’ through SS-5-2’) that were analyzed on-site using a mobile UVF laboratory. Concentrations of TPH-DRO and TPH-GRO less than the RALs were reported in all soil samples SS-1-2’ through SS-5-2’. Soil sample locations and soil quality information for the soil samples collected on January 3, 2023, are shown on Figure 3. A summary of analytical results for the soil samples collected on January 3, 2023, are included as Table 1. A copy of the UVF analytical report for soil samples collected in January 2023 is included as Appendix C. C. SUMMARY AND CONCLUSIONS  On December 27, 2023, reportedly, approximately 100 gallons of diesel fuel was released from the saddle tank of a truck during a vehicular accident on Ludie Brown Road in Chinquapin, NC.  The impacted soil from the spill covered an area of approximately 361 square feet to a depth 2 feet below ground surface bgs.  Based upon onsite mobile laboratory results from January 3, 2022, GRI personnel supervised the excavation of 22.37 tons of soil from area of approximately 361 square feet to a depth 2 feet bgs. During excavation activities, GRI personnel collected soil samples (SS-1-2’ through SS-5-2’) that were analyzed on-site using a mobile UVF laboratory. Concentrations of TPH-DRO and TPH-GRO less than the RALs were reported in all soil samples SS-1-2’ through SS-5-2’.  22.37 tons of impacted soil was excavated from the release area and transported to a licensed disposal facility.  On January 4, 2023, a UST-62 Form was submitted to NCDEQ.  Based on this information, impacted soil has been successfully removed and no further abatement activities are warranted. The incident should be closed with the issuance of a No Further Action. D.

The calibration standards used are as follows: GRO  0.5 ppm  1 ppm  3 ppm  5 ppm  10 ppm DRO  0.1 ppm  0.5 ppm  1 ppm  3 ppm  5 ppm Operation Sample Extraction  5mg of soil are weighed into a clean extraction jar  Methanol is added to the extraction jar to create a 2x or 4x dilution o 2x Dilution: 10 mL of methanol o 4x Dilution: 20 mL of methanol  The extraction jar is shaken for several minutes to thoroughly mix the soil with solvent (methanol)  The mixture is allowed to settle for several minutes  A clean syringe is used to draw liquid from the extraction jar  A clean filter is attached to the end of the syringe and the liquid dispensed through the filter into a clean test tube  This liquid is referred to as the extraction Dilution Preparation  An adjustable micropipette is used to precisely measure out the amount of extract needed for the dilution  The measured out amount of the extract is added to a clean test tube and methanol is added dilute the extract. Examples of dilutions are shown below: Extract Amount 500 μL 200 μL 100 μL 50 μL 25 μL Add Solvent to the 5 mL line 5 mL line 5 mL line 5 mL line 5 mL line 2x Extract Dilution Factor 20x 50x 100x 200x 400x 4x Extract Dilution Factor 40x 100x 200x 400x 800x Technical Procedures Sample Analyzation  The dilution is shaken to thoroughly mix, then poured into a clean glass cuvette  The desired module is inserted into the UVF Trilogy and the corresponding factory calibration is selected  “Measure Fluorescence” is pressed on the touchscreen and the reading is recorded  The reading should be between the concentrations of the calibration standards (GRO: 0.5-10 ppm; DRO 0.1-5 ppm) o Reading below the calibration standard range are recorded as below the detection limit  Detection Limit = (lower range of calibration standards range) x dilution factor (i.e. a GRO sample with a 100x dilution factor has a detection limit of 50 ppm) o Readings above the calibration standard range should be further diluted and reanalyzed o Negative readings are an indication of quenching (see below)  The reading is multiplied by the dilution factor to calculate the final concentration  Check suspected contaminated samples for quenching by running additional dilutions o According to the siteLAB Quick Reference Guide: “Quenching” can occur when the detector is swamped by too many hydrocarbons or organic interferences, producing low or negative concentrations. Test the sample at multiple dilutions to confirm results are linear and accurate.” QA/QC Method Blank  A method blank of methanol will be analyzed following calibration and following the last sample analyzed each day Duplicates  One duplicate will be analyzed for every 20 samples  The duplicate will be prepared from the extract of the sample and diluted to the same factor as the sample analyzed Project Name:Date Collected: Project Number:Date Analysed: Project Manager:Operator: Sample ID Matrix Dilution Factor x GRO Output (ppm) =GRO Value (mg/Kg) Dilution Factor x DRO Output (ppm) =DRO Value (mg/Kg) SS-1-2'Soil 20 <0.5 <10 20 <0.1 <2 SS-2-2'Soil 20 <0.5 <10 20 <0.1 <2 SS-3-2'Soil 20 0.51 10.2 20 0.21 4.2 SS-4-2'Soil 20 <0.5 <10 20 0.13 2.6 SS-5-2'Soil 20 0.54 10.8 20 0.32 6.4 DUP SS-5-2'Soil 20 <0.5 <10 20 0.3 6 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 Soil <0 <0 UVF Analytical Report siteLAB UVF Trilogy 1/3/2023 1/3/2023 Ethan Rogerson Ludie Brown Road Saddle Tank Spill 6340 Ethan Rogerson Site: Ludie Brown Road Saddle Tank Spill Report Date: 1/4/2023 Page: 1 of 1
