U.S. District Judge Gregory Frizzell has rejected Oklahoma's plea to reconsider his previous ruling that barred the state from seeking damages of more than $600 million in its poultry litter lawsuit, according to tulsaworld.com.

The state, led by Attorney General Drew Edmondson, is suing 12 poultry companies for damaging portions of the Illinois River watershed in Oklahoma.

Frizzell also declined to grant an injunction in connection with the land application of poultry litter in the watershed case. A trial is scheduled for September 21.
