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:

Federal prosecutors have handed out more subpoenas in a criminal investigation stemming from the recent coal ash spill in Eden. The government is seeking documents from 20 current and former employees at the Department of Environment and Natural Resources (DENR). Prosecutors are also calling on those individuals to testify before a grand jury. The subpoenas seek records related to cash, items of value or investments that state employees might have received from Duke.

State officials with the Department of Environment and Natural Resources (DENR) have told Duke Energy to stop using a stormwater pipe running under a coal ash pond in Eden. (This is a different pipe than the one that ruptured 17 days ago, causing the third largest coal ash spill in U.S. history.) Following that spill at a retire coal fired power plant north of Greensboro, many environmentalists and media members questioned the durability of this second, smaller pipe. Duke has said repeatedly this pipe is structurally sound and water running through it, is clean. DENR tested some water and determined that not to be the case.

On the afternoon of Sunday, Feb. 3, a security guard at a Duke Energy plant near the North Carolina-Virginia border noticed the water level in a reservoir pond was dropping quickly.

He told facility managers, and what ensued was a chain of relayed messages: First to environmental professionals working for Duke; then local authorities in nearby Eden, N.C., Rockingham County, N.C., and Danville, Va.; the North Carolina Division of Emergency Management; and the state Department of Environment and Natural Resources.

The federal government has issued subpoenas to Duke Energy and the North Carolina Department of Environment and Natural Resources (DENR). The U.S. Attorney is investigating a suspected felony. The subpoenas dated Monday seek a wide range of documents, reports and photographs related to the recent coal ash spill into the Dan River. It’s not clear what felony the federal government suspects Duke or DENR of having committed. A metal pipe beneath a coal ash pond ruptured 11 days ago, sending potentially toxic material into the river.

More than 100 people filled the city hall chambers in Danville, Virginia last night. They heard from federal and state officials about clean-up efforts following a recent coal ash spill in Eden, NC. A pipe underneath a coal ash pond there ruptured ten days ago,

While the state transportation department is already out salting roads, utility companies are closely monitoring the weather forecast today.

National Weather Service Meteorologist Ryan Ellis said light snow is likely this afternoon, getting heavy tomorrow into Thursday. By tomorrow afternoon, he said, ice will coat much of the state.

Jane Pritchard is a spokeswoman for the North Carolina Association of Electric Cooperatives. She said it would take a heavy snowfall to mess with power lines, but just a half-inch of ice can do a lot of damage.

Those 8,000 new street lamps will save money, and are a green choice.

The Town of Cary has announced a partnership with Duke Energy Progress to switch out most of its high-pressure sodium streetlamps (the yellow kind) with LED lamps (the white kind).

LEDs are more easily directed in a specific direction and also more energy efficient. So not only can the town do a better job of putting the light on the road (as opposed to spilling off into the neighboring areas), they'll also save an estimated $200,000 a year.

Environmental groups are asking to take part in negotiations over how to clean-up contaminated ground water sites. The state Division of Environment and Natural Resources – DENR – is trying to reach a settlement with Duke Energy about how to clean up sites contaminated with coal ash, from power plants. Many conservationists don’t think DENR’s proposed settlements will go far enough – and have asked a judge for permission to join the state’s lawsuit as plaintiffs.

Duke Energy is introducing a program to provide its largest customers with renewable power.   The utility's 'Green Source Rider' initiative would give companies that use large amounts of power an option to use renewable energy in their new or expanded facilities.

Duke Energy will ask participating customers what their new power preference is: wind, solar or some other source.  Spokesman Jeff Brooks says it's then up to the utility to find them ample amounts..

Duke Energy is dropping its practice of paying for retirees' health benefits.  The country's largest utility joins companies like IBM, General Electric and Time Warner in the policy change.

 Instead of covering insurance for more than 14,000 retirees, Duke Energy will give them a yearly stipend.  Retirees can use that payment to buy their own coverage.  Dave Scanzoni is a company spokesman.

Duke Energy has filed a motion to dismiss an appeal of the ruling that confirmed the merger with Progress Energy. 

The appeal from the environmental group NC WARN says the state Utilities Commission was wrong to exclude outside parties from an investigation of the merger.  Regulators were looking into why Progress Energy CEO Bill Johnson was ousted as leader soon after the deal was complete last year.

State regulators are considering a plan to allow Duke Energy to charge customers a little more as it increases energy efficiency.

The Utilities Commission held a public hearing yesterday to discuss a proposal from the utility.  Duke Energy spokesman Jeff Brooks says it calls for the company to invest in energy efficiency programs while allowing the utility to recover lost revenue.

The Brunswick Nuclear Plant was ranked one of the most vulnerable nuclear reactors to a terrorist attack.

A new study commissioned by the Defense Department says every nuclear reactor in America is ill-prepared for a terrorist attack. North Carolina's Brunswick Nuclear Plant was ranked among the most vulnerable to attack, because of it's proximity to the Atlantic Ocean.

Kim Crawford is a spokesperson for Duke Energy, which manages four nuclear sites in North Carolina, including Brunswick. She says their plants are safe.
