Although ferric chloride is a corrosive that is harmful to aquatic life, environmental authorities found no evidence of fish kills or water-quality damage because of the large volume of water into which the chemical was absorbed.
“Although we take anything like this very seriously, fortunately there were no environmental issues,” SCE&G spokesman Robert Yanity said.
The material, used as a water-treatment coagulant at the plant, spilled into a storm drain that empties into the plant’s cooling water system and then into the river.
Yanity said the spill was about 275 gallons but was diluted after it reached the river.
South Carolina Depart-
ment of Health and Environmental Control officials called to the spill found no issues requiring action.
