PUBLIC HEALTH SERVICES PpU�N SAN JOAQUIN COUNTYRMC 0 350 S TR0 S TRA��AR 303NMENTAL HEALTH DIVISION 3 TRACY Erh&t M. Fujimoto, M. D., M.P.H., Acting Health Officer 304 E. Weber Ave., Third Floor - P. O. Box 388 - Stockton, CA 95201-0388 On January 23 , 1996 , I 4JW_46,A�*2t RMC Lonestar located at 30350 S . Tracy Blvd . in the unincorporated area south of the city of Tracy. My presence was requested by RMC Lonestar representatives inorder to witness the removal of a 10 , 000 gallon diesel tank, a 1, 000 gallon gasoline tank and a 500 gallon waste oil tank. In attendance were two firefighters from Tracy Rural Fire Department, Chris Rowley of Chromolab, and Yalew Kabede of Sacramento County Environmental Management . Bradd Stately of RMC Lonestar and Joe Medina of Pacific Excavators were conducting the removal . Jim Reese of H and H Environmental would monitor the combustible gas indicator and transport the tanks from the site . I arrived at the site of the 1, 000 gallon gasoline tank and found that the overburden had been removed from the tank . During the excavation of the tank an electrical conduit was unearthed that crossed over the tank . Inorder to remove the tank without damaging the conduit , Pacific Excavators planned on excavating one end of the tank and sliding the tank from under the conduit . While doing the additional digging of the hole a second tank was found. I informed Mr. Stately, that this discovered tank would probably require the payment of the state surcharges and additional removal permit fees . He agreed and requested an appointment for removal of these tanks for the following day. We then moved to the location of the 10 , 000 gallon diesel tank. I saw two individuals working near the tank. It was learned that one of the individuals was the brother-in-law of the contractor. Mr . Stately assisted the contractor with securing the chains to the tank . Mr . Reese took combustible gas readings, 10 of LEL and 18 % Oxygen . The tank showed signs of corrosion and heavy staining around the fill area which was located at the east end of the hole . The tank pit had a slight odor near the east end. Prior to the removal , an underground water line was damaged during the excavation of the tank which left the area extremely muddy. Samples were taken from the bucket at a depth of 14 feet near the ends of the tank . This tank was labeled with paint on each end as 39-1737-2 . The 560 waste oil tank had staining around the fill . The fill pipe was damaged and I was unable to determine when this damage occurred. The LEL was 21 and the oxygen registered 13% . There was contamination in the form of a gray layer to the depth of 5 feet with a very heavy odor from the hole . Samples were taken from the bottom and the east sidewall of the excavation. This tank was labeled with paint on each end as 39-1737-3 . The manifest for the two tanks as 95590444 and manifested to H & H. A Division of San Joaquin County Health Care Services
