foundation. In accordance with Environmental Protection Agency
(EPA) air emission permit requirements, CITGO annually inspects
the tanks’ external and internal floating roof seals and, every
10 years, inspects the external and internal floating roof
mechanisms. CITGO’s tank inspection schedule is also designed to
comply with American Petroleum Institute Standard 653, Tank
Inspection, Repair, Alteration, and Reconstruction (API Standard
653).
Repairing corroded tank floors may involve patching or
replacing the corroded floor plates or completely replacing the
tank floor. In some cases, the tanks are lifted off the ground
in order to repair the floor underside or to perform foundation
repairs. For example, CITGO has lifted tanks Nos. 2 and 3 at the
Vestal, New York, terminal in order to perform foundation
repairs. When performing foundation repairs, lifting the tank
off the ground allows the tank to return to its normal shape.
If refined product leakage has occurred, soil remediation may be
accomplished by lifting the tank, removing the sand underneath,
and replacing the tainted soil with clean soil or, instead of
lifting the tank, by cutting out the tank floor in order to reach
the soil below it.
E. Tank Relocations
In addition to lifting tanks for repair purposes, tanks also
are lifted in order to relocate them either within the same
