CHARLOTTE, N.C. -- Dozens of protestors gathered outside of the Duke Energy headquarters in uptown Charlotte Tuesday.
At first, Duke Energy blocked the doors when they attempted to deliver a petition with 9,000 signatures calling for the company to clean up the leak without passing costs to customers.
After 45 minutes, Duke collected the petition.
The massive coal ash spill in Rockingham County sent 82,000 tons of toxic chemicals into the Dan River. Duke says it plugged the leak that caused sludge to flow into the water.
A criminal investigation is now underway.
