There are <br /> areas of minor to moderate to substantial corrosion with the Body of the tank that should <br /> be repainted soon as part of the ongoing & normal preventative maintenance operations. <br /> The corrosion is external only, as located in this tank and has not impacted the steel <br /> thickness of the outer shell. The corrosion on the supports does not impact the integrity of <br /> the supports in any fashion, but should be monitored and if the corrosion worsens, then <br /> that issue should be addressed, the corrosion removed and the supports repainted. This <br /> external corrosion does not currently impact the stability of the tank nor the containment <br /> integrity of the tank.
