Marine Corps Base (MCB) Camp Lejeune, North Carolina Navy Contract No. N40085-06-D-7006

CTO No. 0004 Dear Mr. Oros: Osage of Virginia Inc. (Osage) is pleased to submit this Report of Findings for soil sampling work performed at the above referenced site. This letter report documents field activities, as well as provides findings and recommendations with respect to the soil samples collected along the underground piping associated with the former UST. Background and Purpose Building 30 is located in the vicinity of Gottschalk Marina aboard Marine Corps Base (MCB) Camp Lejeune, North Carolina. The site location is shown on Figure 1. Building 30 is currently a bathroom facility, with one washer and dryer unit for use by Marina residents. Former UST 30-1 was located approximately 50 feet to the South-Southeast of Building 30. It supplied fuel via underground piping to a dispenser located on the Marina pier, which extends approximately 200 feet from the shore line into the water. The 1,000-gallon steel gasoline tank was closed by removal on July 29, 1993 by Jones & Frank (J&F). Two soil samples from the tank basin were collected and analyzed for Total Petroleum Hydrocarbons (TPH) Gasoline Range Organics (GRO) and Diesel Range Organics (DRO). Laboratory analysis of the soil samples indicated results were below the laboratory method detection limits. The September 3, 1993 tank closure report stated that the product delivery lines were excavated and removed from the subgrade or rendered non-usable.

December 13, 2007 of 3

Upon recent review of the report by the North Carolina Department of Environment and Natural Resources (NCDENR), they requested that MCB Camp Lejeune collect soil samples along the transfer piping and dispenser locations associated with the UST. As part of this investigation, soil samples were collected from the requested areas. Methods Osage personnel conducted soil sampling activities along the suspected location of the underground piping associated with UST 30-1 on October 26 and October 29-31, 2007. Samples were collected along the line from the former tank area northward to where the line attached to the Marina pier. Utility location of the area did not identify any remaining fuel piping. Soil samples from the dispenser area were not collected, as the dispenser was located over water on the pier. The soil investigation involved the advancement of 35 hand augers for collection of soil samples (UST30-1-SB01 through UST30-1-SB35). Samples were visually examined for evidence of a release and screened using a Photo Ionization Detector (PID). One vadose zone soil sample was collected for laboratory analyses from a depth of three feet Below Ground Surface (BGS) at each hand auger boring. The soil samples were placed in laboratory glassware, labeled, placed immediately on ice in a cooler, and transported under proper Chain-of-Custody (COC) protocol to SGS Environmental Services, Inc. (NC Certification #481) of Wilmington, North Carolina. Samples were analyzed for TPH-GRO and TPH-DRO via EPA Methods 5030 and 3550, respectively. Sampling Results Analytical results for the soil samples are summarized in Table 1 and discussed below. The complete laboratory analytical report and COC documentation are included in Appendix A.

EPA Method 5030 As shown in Table 1, analytical results from three of the 35 soil samples revealed noncompliant TPH-GRO concentrations. Soil samples UST30-1-SB11, UST30-1-SB 24, and UST30-1-SB25 contained gasoline range organics at concentrations of 11.8 mg/kg, 37.0 mg/kg, and 11.2 mg/kg, respectively. All other soil sample results were reported as below laboratory quantitation limits (BQL) for TPH-GRO. EPA Method 3550 Laboratory analysis detected TPH-DRO concentrations in 16 of the 35 soil samples. Only six of those 16, however, exhibited noncompliant concentrations. Soil samples UST30-1-SB04, UST30-1-SB11, UST30-1-SB12, UST30-1-SB21, UST30-1-SB22, and UST30-1-SB24 contained diesel range organics above the NCDENR Action Limit of 10 mg/kg. Soil sample UST30-1-SB04 had a TPH-DRO concentration of 47.3 mg/kg, while sample UST30-1-SB11 exhibited the highest concentration of 150 mg/kg. TPH-DRO
