A pipe running under one of the ponds run by Duke Energy in Eden NC ruptured in February of 2014. The coal ash spilled, largely affecting the Dan River which flows into Virginia. The spill is the third largest of its kind in U.S. history.Many see potential complications because North Carolina's governor, Pat McCrory, worked for Duke Energy for 28 years.
