2.3 Removal of Liauids and Sludqes
To expedite the removal process, samples of the liquid and sludge materials
for the on-site tanks and the sump were obtained before implementation of
the work plan. The samples were obtained and tested for compatibility and

requirements as outlined in Section 2.10. Chemical content testing was
performed as required for the determination of the disposal profile and for
acceptance by the Kettleman Hills disposal facility. The results of these
tests are provided in Appendix C.
2.3.1 Sludae Tank
The liquids were removed from the sludge tank by being pumped into 55-

this surface would be kept clean. The drums were placed in a berm
constructed of plastic sheeting and absorbant in case spillage occurred.
Residual sol ids were removed by hand excavations. After cleaning, the tank
was loaded with yard debris, placed on a flatbed truck, and transported to
the Kettleman Hills disposal facility. The tank was picked up by a crane
with steel cables wrapped around each end of the tank and connected in the
middle. The cables were then secured to the lifting arm of the crane and
the tank was lifted onto the truck.
