In the immediate aftermath of last month’s Duke Energy coal ash spill, concerns were raised about the existence of similar pipes at other ponds around the state. Yesterday, the North Carolina Department of Environment and Natural Resources, DENR, confirmed the presence of eight additional corrugated metal pipes at Duke Energy coal ash ponds.

State regulators with the Department of Environment and Natural Resources (DENR) say there are additional metal pipes at Duke Energy coal ash ponds that pose a threat. It was a metal corrugated storm water pipe running under a coal ash pond in Eden that ruptured 31 days ago, setting off the third largest spill of its kind in U-S history. DENR announced today that eight other metal pipes run through retention walls, around coal ash pits, but not under them. These eight serve a different function than the pipe that broke last month. The eight discharge pipes remove surface water from the top of the lagoons once coal ash has settled at the bottom. Duke has previously stated it was unaware of any other metal pipes at its 14 coal-fired power plants.

On February 2, between 50,000 and 82,000 tons of coal ash and 27 million gallons of ash pond water waste were released at Duke Energy’s Dan River Steam Station (pictured above) north of Eden, N.C.

Internal emails released this week reveal that officials with the Department of Environment and Natural Resources (DENR) have been concerned about coal ash ponds at Duke Energy sites for years.

The Southern Environmental Law Center (SELC) obtained the documents as part of its effort to close coal ash ponds throughout the state. The roughly 400 pages of emails reveal employees at the state agency were concerned about storm water runoff at six sites owned by Duke Energy.

Did you miss it? The Diane Rehm Show devoted an episode earlier this week to the coal ash spill in Eden, NC.

(The spill was caused by a pipe failure at a Duke Energy location. Coal ash is leftover from the process of burning coal. The ash is considered toxic, and is held in ponds. This spill is the third largest of its kind in U.S. history.)

This was an interesting part of the show, between Frank Holleman of the Southern Environmental Law Center and Diane Rehm:

At least 30,000 tons of coal ash poured through a broken Duke Energy stormwater pipe and into the Dan River earlier this month. The spill is the third largest of its kind in US history.

But that spill was much smaller than an accident in Tennessee six years ago.

It was the middle of the night, three days before Christmas in 2008 when part of a retention wall at a Tennessee Valley Authority coal ash pond ruptured.  A dike failed and millions of gallons of potentially toxic waste were unleashed.

Governor Pat McCrory has sent a letter to Duke Energy’s CEO asking the company to remove coal ash from sites near waterways. In the letter McCrory says his administration has expressed its primary desire that coal ash ponds be moved away from waterways.

“This is a good development but we’re still dealing with words and not actions,” said Frank Holleman is senior attorney with the Southern Environmental Law Center.”

Officials with the Department of Environment and Natural Resources (DENR) announced Tuesday they might require Duke Energy to remove all coal ash at the site of a massive spill near the Virginia border.

DENR sent a letter to Duke this week, three weeks after the largest spill of its kind in U.S. history. In the letter the state agency informed the utility it’s considering changes to a permit that regulates how much pollutants the company can legally release into the river. The possible change does not apply to the company’s 29 other unlined coal ash ponds.

This week, the NC Department of Environment and Natural Resources, DENR, is testing fish tissue in the Dan River for contamination from the Duke Energy coal ash spill earlier this month.  The Southern Environmental Law Center claims they warned Duke Energy and DENR of a potential spill last year.

NC WARN, a progressive environmental non-profit, is teaming up with an unlikely partner: the John Locke Foundation. The two organizations share a desire to increase competition in the power industry and challenge Duke Energy's monopoly on electricity in the state.

Earlier this month a stormwater pipe running under a coal ash pond in Eden ruptured. It did the following:
