COLUMBIA, S.C. (Aug. 3, 2006) – SCE&G recently receved confirmation from the Federal Energy Regulatory Commission (FERC) that the spillway structure at the Saluda Dam on Lake Murray will not require any work to meet new earthquake safety criteria. According to a letter from FERC received by SCE&G this week, the commission agreed with the engineering analysis submitted by SCE&G that the structure would withstand the strongest predicted earthquake that could be expected to strike the region, and still function properly.

“We are pleased that FERC agreed with our assessment,” said Jim Landreth, vice president of Fossil & Hydro Generation for SCE&G. “This was the final detail in the safety enhancements made to the Saluda Dam.”

Completed in 2005, the backup dam was built to meet changes in earthquake safety criteria as directed by the Federal Energy Regulatory Commission.

On Monday, Aug. 7, SCE&G will begin moving barges next to the intake towers near the dam in preparation for routine maintenance on two of the towers. The maintenance work is unrelated to the backup dam project. The barges will be in place for about two weeks.

“Part of the project will require some increased water releases after Labor Day,” said Landreth.

Landreth said that once the maintenance project is complete, SCE&G will be conducting required dissolved oxygen testing as part of the Saluda Hydro relicensing process. “The testing will take place in mid-to-late September and will last about three or four days,” he said. “The process will require the operation of all five units at the plant at some point, but will have a minimal impact on lake levels.

“As always, our goal for maintenance work and environmental testing associated with the Saluda Hydro Plant is to have as minimal an impact as possible on our neighbors above and below the dam and to provide as much advanced notice as possible,” said Landreth. “We expect the impact on lake levels to be no more than two inches or so.”
