2 . 0 EXECUTIVE SUMMARIES <br /> 2.1 Structural 2.1.1 <br /> Examination Based on the inspection data, it appears that there are some miscellaneous structural <br /> Summary modifications and repairs that are required. These modifications and repairs serve to <br /> bring the tank into compliance with OSHA regulations,AWWA standards, as well as <br /> allow for better coating bonding, allow for safer access in and on the tank and, in <br /> some cases, removing unnecessary items. <br /> 2.2 Coating 2.2.1 Lead and Chromium Content Analysis <br /> Evaluation The total lead content of the interior wet, interior dry and exterior coatings was not <br /> Summary analyzed,this is based upon the year the tower was built. In 1993 Lead based coatings <br /> were not being used. Based upon the tower's location reconditioning specifications <br /> must include provisions for full containment. <br /> 2.2.2 Interior Wet Coating <br /> The tank requires a complete new interior coating within the next 1 to 2 years. It <br /> appears that the tank was last coated in 1993 when the tower was erected, it is 25 <br /> years old and is considered non-repairable. A properly applied and maintained <br /> immersion service epoxy coating should provide twenty (20)to twenty-five (25) years <br /> of service. See photos Appendix A. <br /> 2.2.3 Interior Dry Coating <br /> Overall the interior dry coating is in fair condition. There are random coating failures <br /> throughout the interior dry surfaces. With larger failures in the drywell tube and <br /> above the top landing. <br /> The complete interior dry surfaces should be reconditioned at the same time the tower <br /> is next scheduled for reconditioning. See photos in Appendix A. <br /> 2.2.3 Exterior Coating <br /> It appears that the tank was last spot repaired and coated in 2014. The exterior coating <br /> is not classified as a lead or chromium based paint. It is in fair condition. <br /> Due to age, chalking, and deterioration, the entire exterior coating is not repairable <br /> and should be removed and replaced within the next 1 to 2 years with a <br /> zinc/epoxy/urethane coating system.
