In 2016, the state gave the company until August 1, 2019, to dig up and close some coal-ash pits and nearly a decade more to deal with others.
Upon immediate landfall, the threats are you standard hurricane threats - storm surge, strong winds, tornadoes.
On Tuesday afternoon, data from an Air Force Reserve hurricane hunter aircraft showed that Florence's sustained winds had picked up in speed again, hovering close to 140 miles per hour.
Almost 100 first responders from across Louisiana are preparing to deploy to the Carolinas ahead of Hurricane Florence's landfall, state emergency leaders announced Tuesday.
Hurricane Florence, a powerful Category 3 storm, is closing in on the Southeast, bringing threatening winds, a high storm surge and tons of rain.
In the Pacific, Hurricane Olivia triggered warnings for multiple Hawaiian islands as it blew west towards an arrival over the state as soon as late Tuesday or early Wednesday. Fallen trees and power poles will isolate residential areas.
Astonishing winds aren't the biggest danger. But the firm warns that Tropical Storm Isaac, which formed in the Atlantic Ocean on Saturday, is right behind Florence. It's enough to cover Manhattan with almost 3,800 feet (1.1 kilometers) of water, more than twice as high as the island's tallest building.
Storm surge is basically a wall of water that could swallow parts of the coast.
"We're talking 12-foot seas stretching 300 miles away from the center", the NHC's Graham said.
"It is an extremely risky, life-threatening, historic hurricane", North Carolina Gov. Roy Cooper said. But the storm is expected to strengthen again over the next day or so. No. 14 West Virginia's game at North Carolina State and No. 18 UCF's game at North Carolina are the others.

With "monumental" rainfall totals of up to 40 inches possible, "the rain from Florence may break all-time state records for rainfall from a hurricane or tropical storm", Weather Underground meteorologist Jeff Masters said.
Nearby counties like Pender, Beaufort, Pitt, Greene and Lenoir could see 10 to 15 inches of rain.
What's worse: Much of the Carolinas are already saturated from rainfall. "There is no way to be completely safe", but going inland might not be much safer. Damaging effects from the storm are expected to be felt far inland, particularly as it's projected to stall once it crosses the coastline.
And in the 29 years since Hurricane Hugo struck, the population of the coastal Carolinas has skyrocketed.
Urging residents to evacuate, he said Florence was "the strongest storm to target the Carolinas and this part of the country in decades".
According to the Saffir-Simpson Hurricane Wind Scale, people caught in a Category 4 storm can expect to see "catastrophic damage". Make sure you have your medications. Typically, local governments in North Carolina make the call on evacuations.
"We're a resilient bunch down here". A year ago, people would have laughed off such a forecast, but the European model was accurate in predicting 60 inches (150 centimetres) for Hurricane Harvey in the Houston area, so "you start to wonder what these models know that we don't", University of Miami hurricane expert Brian McNoldy said. "But this is pretty serious". Florence's storm surge threatens more than 750,000 homes in the region, according to the property analytics firm CoreLogic.
