CHARLESTON, S.C. — Attorneys on both sides of a lawsuit over dredging the Savannah River shipping channel want a federal judge to rule in their favor quickly.

Attorneys for the Savannah Riverkeeper, the U.S. Army Corps of Engineers and the Georgia Ports Authority filed requests late last week seeking rulings in their favor without a trial.

Environmentalists have sued saying the corps needs a South Carolina pollution permit for the $650 million project because toxic cadmium will be dredged from the river and deposited on the South Carolina shore.

Maritime interests say the deepening is needed so the Georgia Ports can handle larger container ships that will routinely be coming when the Panama Canal is expanded in 2014.

The CEO of the Panama Canal Authority speaks Tuesday at a trade conference outside Charleston.
