Additional Information: The abrasive blast to the riser and overflow pipes were completed today. This
includes the ladder and braces attached to these pipes. Some twenty (20) to thirty (30) mil deep pits are noted on the
riser pipe on the second and third rings down from the ceiling. These pits are located on the ladder side of the pipe.
The ladder rungs in this area also show signs of metal loss. The top fifteen (15) rungs have varying degrees &metal
loss. The contractor is still blasting on the walls and is not yet ready to coat them. The dehumidifier is running and
appears to be holding the humidity and dew point low enough for surfaces not to rust bloom. The airless spray
application 0fthe prime coat will occur after blasted areas are blown clean and dust has settled.
