Identified Contamination Source Evaluation & Recommendations 9. The former Chevron, Lyoth facility, Because crude oil is not particularly 26501 S. Banta Rd., adjacent to the mobile in soil, it is considered possible but north of the Site, was investigated for a unlikely that the Site could be impacted variety of impacts resulting from its use by the remaining contamination near the as a loading station and the presence of former 55,000-barrel AST. The only way the Old Valley Pipeline (OVP) at the to determine the presence or absence of facility. The OVP was operated from the contamination is by testing and analysis. 1900s to the early 1960s and carried Typically, any testing is conducted at the crude oil and locomotive fuel from property owner's discretion. Bakersfield to Richmond. Three cases related to contamination at the Chevron, According to a document available Lyoth facility were identified, all have through GeoTracker (SAIC, 2009), much been closed. According to the Soil and of the contamination at the Lyoth Loading , Groundwater Investigation Report at cases resulted from a pipeline leak from Lyoth Loading Station (SAIC, 2005), the Old Valley Pipeline, which ran along petroleum-affected soil remains in the the western side of the railroad tracks vicinity of the former 55,000-barrel AST approximately 250 feet northeast of the (adjacent to the north of the Site), Site. Two additional pipelines, operated including crude oil (TPHc) at by the Tidewater Associated Oil concentrations up to 20,250 mg/kg and Company, also ran along the western polycyclic aromatic hydrocarbons side of the railroad tracks. Based on the (PAHs) up to 14,000 mg/kg beneath the distance to these pipelines, contamination footprint of the former AST. However, on the Site resulting from pipeline leaks is no detectable crude oil was found in the considered possible but unlikely. boring closest to the Site in 1995, the sample was collected at a depth of 12 feet.

Banta Rd. located approximately 250 feet northeast The location of this GeoTracker case is of the Site; based on distance, it is unclear. A leak of "petroleum/fuels/oils" possible but unlikely that this case could was reported in 1965; as of 2009, the impac he Site. case has a status of "open--inactive."
