1 Pipe Removal <br />All piping associated with the tank will be removed and disposed of at an appropriate <br />disposal facility. The piping located beneath buildings will not be excavated. These pipes will be <br />' filled with a grout mixture and capped. <br />Anticipated hazards due to this activity include chemical hazard from contact with and <br />inhalation of contaminated soil or contents in the pipes. Physical hazards are described on Page <br />10. <br />Personnel will wear appropriate PPE and follow safety procedures to minimize the risk of <br />' exposure and physical injury. <br />Tank Removal <br />Tank removal will be performed with a backhoe. Care will be taken while removing the <br />tank to reduce the potential for spilling any residual contents into the excavation. Upon removal, <br />the tank will be inspected to determine the number and size of holes and the degree of corrosion <br />present. The tank will be loaded onto a flatbed truck for transport off-site to a licensed facility. <br />The tank ballast slab will be broken up with hydraulic hammer, attached to the backhoe, and <br />removed from the excavation. The concrete will be kept separate from other excavated materials <br />and disposed of at an appropriate facility as hazardous waste. <br />' The tank removal activity presents substantial hazards due to possibility of spill of <br />contaminated tank contents and anticipated possible physical hazards due to the tank's size and <br />the proximity of heavy equipment. Personnel shall remain at a safe distance from the equipment <br />and the tank and respect standard safety procedures and directions from the site safety <br />coordinator. Appropriate PPE will prevent contact with or inhalation of contaminated material. <br />Personnel will be instructed on possible physical hazards prior to the start of the work. Air <br />monitoring will be provided to ensure safe working conditions in the vicinity of the tank and <br />excavated material. <br />Excavation of Contaminated Material <br />' Based on laboratory analytical results, the excavated soil will be disposed of in a Class I or <br />II landfill. If no visual contamination exists and the photoionization detector (PID) measurements <br />are equal to background measurements, samples will be taken from below the tank and associated <br />piping; and the pit will be backfilled and compacted with clean soil and brought up to grade. <br />A-4 <br />1: <br />
