Duke Energy: Second Toxic Leak At North Carolina Coal Ash Dump (VIDEO)

On Sunday, a Duke Energy-owned pipe underneath an unlined coal ash dump in Eden, North Carolina shattered, releasing up to 82,000 tons of highly toxic coal ash into the Dan River, a source of drinking water, fishing and recreation.

The Dan River, which is already contaminated from a massive Feb. 2 spill, is apparently being contaminated now by groundwater containing unsafe levels of arsenic from a Duke Energy coal ash dump, North Carolina officials said Tuesday.

Duke have been ordered by the state Department of Environment and Natural Resources to stop the flow of contaminated water coming out of a pipe that runs under a huge coal ash dump at its Eden power plant, the Associated Press reported.

Two weeks ago, the bottom of the Dan River was coated with toxic ash as far as 70 miles downstream when a nearby pipe at the same dump collapsed without warning.

According to the AP, state regulators expressed concern five days ago that the second pipe could fail, triggering a new spill.

The water coming out of that pipe contains poisonous arsenic at 14 times the level considered safe for human contact, according to test results released by the state on Tuesday.

“We are ordering Duke Energy to eliminate this unauthorized discharge immediately,” said Tom Reeder, director of the N.C. Division of Water Resources.

Wide gaps between seams through which groundwater is gushing in, likely from the toxic dump above, were seen in a video taken last week by a robot sent inside the 36-inch-wide concrete pipe.

“Tests on water from the pipe before it goes under the dump showed none of the dangerous contamination detected at the other end,” the AP reported. “The concrete inside the pipe is heavily stained around the numerous leaks, suggesting the contamination is likely not new.”

“A state inspector received the video recorded by Duke during a Feb. 11 visit to the site, but did not review it until Thursday. On Friday night, the state agency went public with concerns about the pipe’s structural integrity.”

Downplaying the risk, Duke spokeswoman Paige Sheehan quickly issued a statement.

“After reviewing the videotape, we determined that no immediate action was necessary,” it said.

People were advised by public officials to avoid contact with the river and not eat the fish in wake of the initial spill.

“Authorities said public drinking water in Danville, Va., and other communities downstream of the Duke plant remain safe,” the AP reported. “Heavy metals detected in the river at levels exceeding state and federal safety standards – including arsenic, lead and selenium – are being successfully filtered out of water drawn from the river at municipal treatment plants, they said.”

A massive pile of coal ash about 75 feet long and as much as 5 feet deep has been detected in the river by the site of the Feb. 2 spill, the U.S. Fish and Wildlife Service said Tuesday.

Deposits varying from 5 inches deep to less than 1 inch coated the river bottom across the state line into Virginia and to Kerr Lake, a major reservoir, the AP reported.

Fish, mussels and other aquatic life might get plagued with the long-term effects of the contaminants, federal authorities said.

“The deposits vary with the river characteristics, but the short- and long-term physical and chemical impacts from the ash will need to be investigated more thoroughly, especially with regard to mussels and fish associated with the stream bottom and wildlife that feed on benthic invertebrates,” said Tom Augspurger, a contaminants specialist at the federal wildlife agency.

Benthic invertebrates are small animals that live in the sediments of rivers and lakes, such as clams, worms and crustaceans.

“The Dan River system in North Carolina and Virginia is home to two federally listed endangered species, the Roanoke logperch fish and the James spinymussel,” according to the AP. “The river also has another freshwater mussel, the green floater, which is currently being evaluated for protection under the U.S. Endangered Species Act.”

The AP continued, “Officials said the coal ash is burying aquatic animals and their food. The ash, created when coal is burned to generate electricity, could also clog gill tissues in fish and mussels. The agency said public reports of dead aquatic turtles at two state parks in Virginia had not yet been verified by federal biologists.”

The toxic ash could be washed further downstream due to the increased flow in the river resulting from last week’s snowfall and rain, the U.S. Environmental Protection Agency warned. The Dan flows back across into North Carolina before emptying into the Albemarle Sound.

After officials in North Carolina and other states approved hikes in the rates customers pay for electricity, Duke Energy announced Tuesday that its fourth-quarter profits jumped 58 percent. The company had revenues of $24.6 billion for 2013.

George Everett, Duke’s director of environmental and legislative affairs, told state legislators this week that the company is sorry for the spill and will be accountable.

Any costs incurred because of the cleanup will likely be passed on to ratepayers, not shareholders, he said.

“We have paid absolutely no attention to costs, to this point,” Everett said, responding to a lawmaker’s question about who will pay. “We’re focused on stopping the discharge and initiating the remediation of the river. But when costs do come into play, when we’ve had a chance to determine what those costs are, it’s usually our customers who pay our costs of operation.”

It would be up to the N.C. Utilities Commission to approve any new rate hikes for Duke. Members of that board are appointed by Gov. Pat McCrory, who worked at Duke for 28 years, the AP reported.
