Gov. Nathan Deal has promoted Deputy State Treasurer Steve McCoy to the top post and appointed a state senator to replace him.
McCoy replaces Tommy Hills, who announced his retirement last month.
McCoy has served as deputy state treasurer and chief investment officer since August 2011.
Republican Sen. Mitch Seabaugh, of Sharpsburg, will succeed McCoy. Seabaugh first was elected to the state Senate in 2000 and served most recently as the Senate's redistricting committee chairman. He is an accountant and works as a chief financial officer in Newnan.
Deal has called for a special election to replace Seabaugh on Nov. 8.
McCoy and Seabaugh begin their new duties today.
The U.S. Coast Guard is completing an oil spill cleanup on the Savannah River.
The Savannah Morning News reported the Coast Guard said about 2,000 gallons of fuel oil spilled into the Savannah River and onto the deck of the motor vessel Ever Diadem, a 965-foot-long container ship, when its fuel tank was overfilled Saturday. The ship was docked at the Garden City terminal and was being refueled.
The Coast Guard said Monday the source of the spill was secured Saturday and about 6,000 feet of boom was placed in the river to minimize the spread of fuel.
Coast Guard Air Station Savannah conducted flights to assess the environmental impact and Coast Guard Marine Safety Unit Savannah personnel coordinated the cleanup efforts.
