JEFFERSON CITY, MO - State utility regulators plan to continue their investigation into the Taum Sauk reservoir collapse.
Ameren Corporation asked the Missouri Public Service Commission to halt its investigation.
But the PSC denied that request and instead has scheduled another round of hearings beginning Monday.
The commission already has heard from several witnesses in the past two weeks.
It's looking into the reason for the December 2005 reservoir failure and whether there are any systematic safety concerns at the utility company.
The reservoir breach sent more than one billion gallons of water down a mountainside. It wiped out Johnson's Shut-Ins State Park and injured the park superintendent's family.
