JEFFERSON CITY, MO - Criminal investigators for the Environmental Protection Agency are looking into the Taum Sauk reservoir collapse.
The retaining wall and around the hilltop reservoir gave way in December of 2005, sending more than one billion gallons of water rushing through Johnson's Shut-Ins State Park. Parts of the southeast Missouri park just reopened yesterday while the cleanup continues.
The reservoir is owned and operate by power company Ameren, which says through a spokesman that it will cooperate with any investigation.
Documents obtained by The Associated Press show the EPA's Criminal Investigation Division requested and received a copy of the Highway Patrol's investigation into the reservoir collapse.
Any EPA findings would go to the U.S. attorney's office for a decision on charges.
