The spill, caused by a ruptured pipe near the Georgia Highway 17 bridge over Reedy Creek, involved de-gritted kaolin slurry owned by KaMin LLC, whose Georgia offices are in Macon.
“Based on the 679-ton number, they calculated the release was 187,000 gallons of de-gritted kaolin slurry,” said EPD spokesman Kevin Chambers.
The 7.5-mile pipline has been taken out of service until the cause of the failure can be determined, said KaMin vice president Doug Carter.
The company is also developing a monitoring plan to evaluate the impact of the spill. Reedy Creek flows into Brier Creek.
