Ameren has released its last inspection (Dec. 8, 2005) of the Taum Sauk Upper Reservoir that collapsed on Dec. 14.
Astonishingly for a structure that was once the definitive engineering marvel for Missouri, the inspection involved only four items and those items only had to be inspected once a week:
First aid kid in bldg. by phone - note needs, restock.
Gauge house - Check levels with staff gauges. Needs? Check battery chargers; check lights, relamp as needed. Check heaters during winter months.
Life-rings at observ. platform & gauge house - note needs.
Air, oil, water leaks - note in Comments
The report was submitted Jan. 10 to the Federal Energy Regulatory Commission notes that there were no mechanical checks of the Upper Reservoir.
Ameren performed function checks on the level control insturmentation to verify their accuracy. Taum Sauk personnel performed functuional checks for the lower reservoir by comparing the level control readings against a staff gauge. For the upper reservoir, level control readings were compared against demarcation marks on the staff gauge mounted on the parapet wall.
Taum Sauk personnel performed these checks on a weekly basis s and recorded that the checks were completed ona document titled Taum Sauk Plant Routine Inspection. Any noteworthy observations were noted; quantitative data was not recorded.
As more and more comes out, it should be obvious that the designers ever dreamed that the power plant would be monitored by staff 100 miles away. When we visited the plant in 1969 it was a hive of activity. When we visited during the 1998 Highpointers Convention we didnt see a single person even at the museum.
