>> Duke Energy says it's been forced to shut down its natural gas plant in Wilmington, North Carolina, because of flooding caused by Hurricane Florence. The company says that walls encompassing a cooling lake at the facility have been breached by flood waters, and that a steel retaining wall containing one of three large coal ash dumps lining the lake may also have been overtopped.
Duke says it can't rule out the possibility of ash escaping into the swollen Cape Fear River. Last weekend, Duke reported two coal ash leaks from a retired plant nearby, both triggered by Florence. In 2015, the company was fined more than $100 million after a coal ash spill that, at the time, was the third worst in US history.
