These areas comprised less than <br />0.03% of the interior surface area of the dry riser. A fair amount of rust staining was <br />noted on the top of condensate ceiling. This staining was most likely caused by areas of <br />the pedestal stiffer rings that were cut to allow cellular antenna cable routing. In these <br />areas the edges of the cut stiffener or the new toe plates added were not cleaned and <br />painted. Areas where the paint was burned due to welding on the exterior of the pedestal <br />during cellular antenna installation were cleaned and touched-up. <br /> <br /> <br />Photograph 30 - Bottom Side of Condeosate Ceiling <br /> <br />Elevated Water Storage Tank <br />City of Arden Hills South Tank <br /> <br />29 <br />
