RALEIGH, N.C. (AP) — Federal authorities have launched an investigation into North Carolina's environmental agency, following a massive coal ash spill on the Dan River.
The U.S. Attorney's Office issued a grand jury subpoena requesting records from the North Carolina Department of Environment and Natural Resources. They include emails, memos and reports from 2010 to the Feb. 2 spill.
The spill occurred at a 27-acre Duke Energy coal ash pond, spewing up to 82,000 tons of coal ash mixed with 27 million gallons of contaminated water into the waterway.
The spill, discovered by a security guard, is the third-largest in U.S. history.
On Wednesday, a North Carolina agency warned people not to eat fish near the site of the spill and to avoid contact with the river near the area.
