Ameren Engineer Repeatedly Denied on Taum Sauk Repair Requests

JEFFERSON CITY, MO - An Ameren engineer says he tried for several days to get the go-ahead for repairs at the Taum Sauk reservoir.  He was denied each time, and several weeks later, the reservoir failed.

Project engineer Steve Bluemmer testified as part of an investigation by the Missouri Public Service Commission into the December 2005 reservoir collapse.

Ameren officials previously acknowledged that water-level sensors weren't accurate and an emergency shut-off sensor was placed too high when water flowed over the top of the reservoir.

Bluemmer says he became aware the water-level sensors weren't accurate in October 2005 and sought permission to drain water from the reservoir so he could fix them.  He says he was denied by Ameren at least five days in a row.
