Spill Response Actions Report California Central Traction Company, Lodi Avenue Right-of-Way, Lodi,CA May 5,2011 Page 2 The left saddle tank of the truck was ruptured during the crash and a quantity of diesel fuel (estimated at less than ioo gallons)was spilled. The spilled fuel remained localized within depressions in the soil created by the tires of the truck during the crash allowing recovery of approximately 50 gallons during initial response actions performed by CCT personnel. Unfortunately,the City of Lodi fire and police dispatch failed to make a timely notification to the railroad of the accident and fuel spill. As a result,the spill was discovered independently by CCT personnel during a routine inspection at approximately 1400 hours on April 7, 2011. CCT personnel responded at approximately 150o hours on April 7, 2011 with a pump and containment barrels to handle the fuel that had accumulated within the depressions in the soil. CCT personnel recovered approximately 50 gallons of fuel and removed the most visibly saturated soils. The wastes were temporarily stored in two 55-gallon drums. Following notification by the Lodi Fire Department of the diesel fuel spill,the SJCEHD requested CCT perform additional response actions to further remove soils impacted by the diesel fuel spill. On Monday,April 11, 2011, spill response actions were completed at the Lodi Avenue ROW. Mr. Garrett Backus,and inspector with the San Joaquin County Environmental Health Department (SJCEHD),was onsite to observe the removal actions. Mr. Keith Woodburne, a professional geologist and project manager from TRC,was also onsite at the request of CCT to provide technical oversight and management during the soil removal actions. Under the direction of the TRC representative, a crew from CCT conducted soil removal actions to address the areas of visible fuel impact to the soils. Using a bobcat and hand tools, CCT removed all visibly impacted soils(Photographs 2, 3&4). At the completion of soil removal actions on Monday the excavation dimensions were approximately 27 feet long by 16 feet wide,with the deepest linear portion along the cemetery fence line at a depth of approximately 2 feet(Photograph 5). Removed soils were temporarily staged on plastic adjacent to the excavation and covered at the completion of Monday's response actions(Photograph 6). Following removal of all visibly impacted soils,and with concurrence from the SJCEHD inspector,TRC collected confirmation soil samples from the bottom of the excavation. A total of three(3)confirmation samples were collected across the full length and deepest portion of the excavation(CS-1, CS-2 and CS-3). The three confirmation samples were submitted to a state- certified laboratory and analyzed for total extractable petroleum hydrocarbons(TEPH)in the diesel and motor oil range by EPA Method 8o15M. In addition,the soil stockpile was sampled at four(4)locations(SS-1,SS-2, SS-3 and SS-4) and those samples were composited into one sample by the laboratory and analyzed for TEPH by EPA Method 8o15M,for volatile organic compounds(VOCs)by EPA Method 826oB, and for CAM 17 Metals by EPA Method 6010 in order to develop a waste profile. Copies of all laboratory analytical reports and chain-of-custody documentation are included in Appendix B. With the exception of one sample(CS-1),the soil sample results confirmed that soil removal actions completed on Monday were primarily successful(Table 1). Elevated TEPH-diesel at a concentration of 20,000 milligrams per kilogram(mg/kg)was reported in confirmation sample CS-1. Based on this result, additional over-excavation activities were completed on Friday,April 15, 2011 prior to stockpile loading and waste transportation and disposal. Additional soil was removed at the location of confirmation sample CS-1 to a total depth of approximately 3.5 feet (Photograph 7).
