Corral Hollow Landfill 31130 S. Corral Hollow Road, Tracy Texaco Pipeline Leak Short Term C0003088 Program Element 24.46 12/21/94 8:42 received a call from Mike Parisi of OES. He said that there was a pipeline rupture at Corral Hollow landfill. He said that the pipe was leaking at a rate of 20 gallons per minute. He said that there was a 1/2 mile of oil. He said Spectrum was performing the drilling and that he would call fish and game. I asked Ed Padilla of PHS/EHD if he knew of any drilling that was occurring at the landfill. He said that PHS/EHD had approved a workplan for SCS Engineering to install vapor extraction wells at the property boundaries of the landfill. The site plan shows the location of the pipeline and the proposed well locations. 10:00 arrived on site. I spoke with Jeff Briggs of OES. We looked at the spill. The drill rig was positioned with 7 feet of auger in the hole. Crude oil was spilling over the top of the auger and through the auger screw holes. The crude oil was flowing in the landfill perimeter storm drainage ditch. The spill was diked and running into two impounded areas. The crude appeared to be liquid where it was coming out of the auger and increased in viscosity as it approached the second impoundment which is about 1000 feet south of the auger. The crude oil had not reached reached Corral Hollow Creek. The southern impoundment is approximately 375 feet north of the bank of Corral Hollow Creek. Jeff said he called Fish and Game, State OES, the State Fire Marshall, and Texaco. I spoke with Edward Perez of B and R Oil Field Services Inc., contractors license 433432 Bakersfield phone number 589-3388. His company performs pipeline maintenance for Texaco. His crew was responsible for diking the contamination and was removing the landfill perimeter fence while we were talking. Gabe Karam of San Joaquin County public works and Karl Barber of SCS Engineers were the next people to arrive on scene. SCS Engineers is the consulting firm which has the contract to install vapor monitoring wells around the perimeter of the landfill. 10:25 I called in to Doug to inform him of my assessment of the extent of the contamination. Next on scene was Lori Oldfather of Fish and Game. Her concern was with the condition of Corral Hollow Creek. She left the scene when she was satisfied that the creek was not impacted. Next on scene was Fernando Ramirez of Texaco. He informed me that the damaged section of pipeline has been isolated by turning off the upstream and the downstream valves. The upstream valve, coming from Coalinga, is four miles south of the damaged section. The downstream
