D. Tank Corrosion, Inspection, and Repair
Because steel tends to rust, tank corrosion is inevitable.
In extreme corrosion cases, a pit will develop in the steel
plates and lead to leakage. Additionally, tank foundations may
settle at different levels under a tank, creating stress on the
tank shell and causing the tank to lose its original shape. In
order to combat these problems, CITGO has an extensive program to
prevent and monitor corrosive damage to the tanks and to monitor
structural problems due to foundation settlement.
Pursuant to its inspection program, at least every 10 years,
CITGO cleans and inspects each tank. CITGO conducts inspections
visually and with electronic devices that gauge the floor plate
depth. In some cases, CITGO lifts the tanks into the air to
provide a better view of the tank bottom or to inspect the tank

feet tall, with a cone roof, an internal floating roof, and a
diameter of 67 feet.
