Background and Initial Response Activities On September 28, 2022, a tractor-trailer operated by United Road and Pilot Transport (United) was involved in an accident alongside Westbound Interstate 40/85, near exit #143, in Burlington, Alamance County, North Carolina. As a result of the incident, approximately 60 gallons of diesel fuel were released from one of the vehicle’s saddle fuel tanks to paved and unpaved surfaces of the roadway shoulder. The approximate location of the site is graphically presented on Figure 1 and Figure 2 (included in Appendix A) and is situated at approximate coordinates 36.064921278 N and -79.45789998 W. A map of the area impacted is included as Figure 3. On the day of the incident, United contacted ERTS and notified them of the incident. ERTS contracted First Call Environmental (FCE) for spill response services. Personnel and equipment from FCE responded to the site on the date of the incident. Response activities included the removal of diesel fuel, and the deployment of granular absorbents and absorbent pads. After the response activities were completed, additional diesel fuel impacted soil remained at the incident location and needed to be appropriately remediated. Due to highway safety and traffic concerns, the NCDOT requested that any soil excavation be conducted during non-daylight hours. On October 19, 2022, FCE subcontracted Highlands Environmental Solutions, Inc. (HES) to provide environmental oversight, and sampling services. A site-specific health and safety plan (HASP) was developed by HES for site remediation activities. A copy of the HASP is included in Appendix B. FCE also contacted the North Carolina 811 service to locate and identify any potential underground utilities at the site. On September 29, 2022, ERTS completed and submitted an UST-62 (24-Hour Notification of Discharge Form) document to the North Carolina Department of Environmental Quality (NCDEQ), Fayetteville Regional Office, reporting the discovery of the release. A copy of this submittal is included in Appendix C C. Free Product Investigation and Recovery As noted in Section B, on the day of the incident, FCE personnel conducted emergency abatement activities included the removal of approximately 48 gallons of diesel fuel product from the grassy surface, and the deployment of granular absorbents, absorbent pads, and hydrocarbon socks along areas of impact. At the completion of the recovery activities, the area of impacted soil was covered with plastic sheeting pending excavation activities. The recovered fuel was containerized in one 55-gallon steel drum and was transported to Spectra Environmental Group in Maryville, Tennessee for disposal. Recovered sorbents were containerized in one 55-gallon drum and transported to the same facility for disposal. Copies of waste disposal documentation is included in Appendix D. D. Groundwater and Surface Water Investigation As noted above, the released diesel fuel did not migrate beyond the localized areas of impact. The closest surface water body is a tributary of Gum Creek located approximately 558 feet West of the release location. Groundwater was not encountered during initial response activities; therefore, a groundwater investigation was not performed during site activities. E. Initial Response and Abatement Activities. Initial response and abatement actions are summarized above. Initial Assessment Report United Road Diesel Fuel Release Incident; Burlington, NC Page 3 F. Excavation of Petroleum Impacted Soil On October 25 and 26 , 2022, personnel from HES and FCE mobilized to the site and conducted soil excavation activities. Select photographs of the site and remediation activities are included in Appendix E. The ultimate objective for this phase of abatement was to remove petroleum-impacted soils and collect post-excavation soil samples for laboratory analysis. FCE utilized a track mounted mini excavator to excavate petroleum-impacted soil. Field indicators were utilized (i.e., staining, and/or odor) and HES collected random soil samples from excavated areas to field screen for organic vapors using a photoionization detector (PID – Mini Rae 3000). To field screen the samples, an aliquot of soil was placed in a clean, labeled, zip-lock bag and allowed to volatilize for approximately 10 minutes. At the end of the volatilization period, the sampling probe for the PID was inserted into the bag to screen for the presence of organic vapors. Utilizing these techniques, HES determined the estimated final limits of the horizontal and vertical extent of impact. The extent of the excavation resulted in a rectangular shape, measuring approximately 76 feet long, by 6 feet in width with depths ranging from 0.5 to 1.5 feet below the land surface (bls). Following completion of the excavation, HES personnel collected four sidewall post-excavation confirmation soil samples (“SW-1” through “SW-4”) and four floor post excavation samples (“FL-1” through “FL-4”) for laboratory analysis. A diagram depicting the excavation and sample collection locations is included as Figure 4. Select photographs of the remediation activities are included in Appendix E. Upon collection, the confirmation samples were split into two aliquots. The first aliquot was placed in a clean zip-lock bag and field screened for organic vapors using the previously described methodology. The second aliquot was placed in labeled, laboratory-supplied containers (pre-preserved) and maintained on ice pending delivery to the analytical laboratory. At the conclusion of the field activities, on October 26, 2022, the soil samples were delivered via overnight courier to SGS North America, Inc., in Orlando, FL. The samples were analyzed for diesel range organics (DRO), using Method 3541/8015; and gasoline range organics (GRO), using Method 5035/8015. Sufficient sample volume was also collected and submitted for potential expanded analysis of volatile organic compounds (VOCs), by Method 8260; and semi-volatile organic compounds (SVOCs), by Method 8270 if needed. As a result of the soil excavation activities, approximately 11.25 tons of impacted soils were transported off site to Environmental Soils Inc, located in Lattimore, N.C. for final disposal. A copy of the waste manifests are included in Appendix D. A summary of the soil analytical data is presented in Table 1 included as Appendix F. The complete laboratory analytical data reports and chain-of-custody records for all samples are included as Appendix G. Laboratory analysis of the soil samples resulted in the detection of DRO in all eight samples at concentrations ranging from 4.0 mg/kg, to 97.8 mg/kg. GRO was not detected at concentrations greater than the detection limit in all eight samples analyzed. None of the reported concentrations of DRO exceeded the NCDEQ State Action Limits of 100 mg/kg. G. Conclusions and Recommendations As a result of a tractor trailer accident on September 28, 2022, a release of approximately 60 gallons of diesel fuel impacted the unpaved and paved surfaces of the roadway shoulder alongside Westbound Interstate 40/85, near Exit #43, in Burlington, Alamance County, North Carolina. On the day of the incident, United contacted ERTS regarding the incident, and ERTS contacted FCE to conduct emergency response activities. Initial response activities included the removal of approximately 44 gallons of diesel fuel, and the deployment of granular absorbents, and absorbent pads. Initial Assessment Report United Road Diesel Fuel Release Incident; Burlington, NC Page 4 On October 25 and 26, 2022, personnel from HES, and FCE mobilized to the site and conducted soil removal/abatement activities. A total of 11.25 tons of petroleum impacted soils were removed for disposal. Laboratory analysis of the eight post-excavation soil samples did not result in the detection of DRO or GRO at concentrations greater than their respective NCDEQ State Action Limits. All appropriate environmental remediation activities have been completed, and all waste materials have been properly disposed. Based on the results of this investigation, HES concludes that the subject release has been properly remediated and does not pose a threat to the environment or human health and safety. HES recommends that this incident receive regulatory closure, and that correspondence documenting no further action required notification be forwarded to United Road for this incident. 491 APPENDIX A Drawing / Project Name Client Project # Date N Base diagram from Google Maps Incident Location Diagram Westbound Interstate 40-US (near Exit 143) Alamance County, NC First Call Environmental / United Road and Pilot Transport Incident Location DB Fig. Scale 340049 NTS Nov 2022 1 PM PG RS PE JB JB     Drawing / Project Name Client Project # DB Fig. Scale Date N Base diagram from USGS Topographic Quadrangle; Burlington, NC Topographic Location Diagram Diesel Fuel Spill Assessment Burlington, Alamance County, NC First Call Environmental / United Road and Pilot Transport 340049 JBNot to Scale Nov 2022 2 PM PG RS PE   JB Incident Location      Drawing / Project Name Client Project # Date N Base diagram from Google Earth Area Diagram Diesel Fuel Spill Assessment Burlington; Alamance County, NC First Call Environmental / United Road and Pilot Transport Incident Location DB Fig. Scale 340049 As Shown Nov 2022 3 PM PG RS PE JB JB    feet  Approximate Scale 0 275 550 Limits of Excavation: (76' by 6' at depth of 0.5' /1.5') US Hwy 70/Interstate 40 (West Bound)SW-1Edge of PavementConcrete MedianFL-11.5' Depth1.0' Depth0.5' DepthSW-4SW-3SW-2FL-4FL-3FL-2PG:DB:Project Number:Date:Scale:PE:PM:Drawing NameSite / Client NameFig.LegendApproximate Scale02040NfeetExcavated Area 1.0' DepthSoil Sample LocationExcavation Area 1.5' DepthExcavation and Sample Location DiagramDiesel Fuel Release IncidentBurlington, NCFirst Call Environmental / United RoadJBRSRS340049November 2022As Shown4Excavated Area 0.5' Depth 491 APPENDIX B Highlands Environmental Solutions, Inc.
