ST. LOUIS, MO - Missouri utility regulators will reopen their investigation into the Taum Sauk reservoir collapse after learning that Ameren Corporation readjusted crucial safety gauges at the facility and removed the guages after the basin collapsed.
Missouri Public Service Commission Chairman Jeff Davis says he made the decision after The Associated Press reported that Ameren employees removed the guages immediately after the reservoir collapsed December 14, 2005.
Information about the guages was detailed in a recently released 2,000-page Missouri Highway Patrol report.
Ameren spokeswoman Susan Gallagher would not comment on the probes. She said Ameren has cooperated with authorities and has spent more than $40 million to repair damage from the accident.
