The Georgia Ports Authority has joined a South Carolina state agency in agreeing to a settlement that would end pending lawsuits over the proposed $652 million deepening of the waterway to the Port of Savannah.

The deal would require extra environmental studies and mitigation by the Army Corps of Engineers.

Georgia port officials would have to spend more than $25 million extra on conservation efforts.Georgia's ports board voted to approve the settlement Wednesday, hours after the Savannah River Maritime Commission in South Carolina agreed to it.

U.S. Senator Saxby Chambliss

A congressional aide says Republican Sen. Saxby Chambliss of Georgia won't seek re-election to a third term.

The conservative lawmaker was first elected to the House in the 1994 Republican wave. He moved up to the Senate after a rough 2002 campaign in which he defeated Democratic incumbent Max Cleland, a triple amputee from his Vietnam war service.

The aide spoke on condition of anonymity because he was not allowed to speak in advance of an official announcement.

Major League Baseball expanded its playoff format to 10 teams Friday, adding a second wild-card in each league.

The decision establishes a new one-game, wild-card round in each league between the teams with the best records who are not division winners, meaning a third-place team could win the World Series.

This is the only change in baseball's playoff structure since the 1995 season, when wild-card teams were first added.
