KNOXVILLE, Tenn. (AP) - Plaintiff attorneys who contend the Tennessee Valley Authority is liable and should pay damages for the Kingston Plant coal ash spill are waiting their turn to cross-examine TVA's spill report consultant at a Knoxville trial.
Geotechnical engineer William H. Walton oversaw a $3 million study by AECOM USA Inc. on the cause of the Dec. 22, 2008, ash spill. In questioning Thursday by a TVA attorney, Walton described the report that places much of the blame for the dike breach on a "slime layer" of watery ash deep underneath the surface.
Attorneys for property owners suing the TVA contend negligence in management and training practices caused the disaster.
The trial is expected to continue into next week. Another trial is set Nov. 1.
