wet interior, although, there were no signs of damage due to ice <br /> movement within the tank (photos 46-48). <br /> According to Ciry records, the coating system was applied with the <br /> original construction of the tank in 1992. Paint records indicate that <br /> there have been no overcoats applied to the tank since the original <br /> construction. <br /> As part of the tank evaluation, SEH inspectors conducted adhesion <br /> tests on the existing exterior coating to determine how well it <br /> presently bonds to the steel surface below. The adhesion tests on the <br /> � exterior of the flute and the roof indicate that the existing coating <br /> system is in fair condition,with satisfactory adhesion to the metal <br /> ' surface and can support an overcoat of paint as part of the <br /> y `� � ', rehabilitation procedure (photos 11, 34). <br /> ,� Based on the original construction date, the existing coatings were not <br /> � <br /> ' tested for the presence of heavy metals.
