SITE LOCATION <br /> Lawrence Livermore National Laboratory (Site 300), Corral Hollow <br /> Road, Building 865 Advanced Test Accelerator Facility, Tracy, <br /> California. <br /> SCOPE OF WORK <br /> Underground storage tank (UST) 865-D1U1, south of Building 865, <br /> will be closed by excavation and removal. The site for excavation <br /> will be cordoned off for the protection of other LLNL personnel. <br /> Solid carbon dioxide (dry ice) will be introduced into the tank to <br /> displace oxygen within the tank. When the oxygen level within the <br /> tank is at or below 5%, the tank will be removed. The tank and the <br /> piping will be transported as hazardous waste to a disposal facility. <br /> If a concrete anchor pad is present beneath the tank, it will be <br /> removed as part of this tank closure. Soil samples will be collected <br /> by LLNL's Environmental Protection Department (EPD) for laboratory <br /> analysis. Soil will be stockpiled on and covered by polyethylene <br /> sheets. The excavation, trenches and stockpiled soil will be secured <br /> with barricades pending the analysis of the soil samples and <br /> subsequent review of the laboratory results by the LLNL EPD. <br /> ON-SITE ORGANIZATION <br /> Site Safety Officer (SSO): <br /> Bill Goodwin <br /> • Responsible for implementing the project and obtaining any <br /> necessary personnel or supplies to complete the project safely <br /> and in a timely manner. <br /> • Monitors adherence to the SHASP and halts site operations if <br /> the SHASP is being violated or if a hazardous condition arises <br /> at the site. <br /> Contractors (Company)-----------_ <br /> ------------------- <br /> (Supervisor)------------------------------ <br /> (Workers)------------------------------- <br /> (Company) <br /> ------------------------------ <br /> (Company)------------------------------- <br /> (Supervisor)------------------------------ <br /> (Workers)-------------------------------- <br /> ------------------------------------ <br /> SAFETY TRAINING <br /> D-2 <br />
