Officials with the Department of Environment and Natural Resources (DENR) have announced they are abandoning a proposed settlement with Duke Energy over the clean-up of coal ash. The proposed settlement would have levied Duke with a $99,000 fine, but had no requirement to remove or clean-up coal ash at two sites in the state.

A federal grand jury has been impaneled to hear evidence about the relationship between Duke Energy and the Department of Environment and Natural Resources (DENR). At the same time, that state agency is investigating the discharge of water by the utility at a site in Chatham County. Guest host Phoebe Judge talks with WUNC's Jeff Tiberii about the latest developments on The State of Things today.

First, the court proceedings:

The highly criticized relationship between Duke Energy and DENR is the focus of the federal investigation. The U.S. Attorney's office is demanding that Duke Energy and the Department of Environment and Natural Resources hand over records of wire transfers, receipts and any items of value that might have passed between the two.  Twenty current and former state employees have been called to testify before a grand jury about their relationship with Duke Energy. The company and state utility commission also received subpoenas.

On Friday the Department of Environment and Natural Resources (DENR) announced it plans to modify Duke Energy water permit. Those water permits are administered by the state and adhere to federal guidelines for discharge. DENR says it plans to change permits so that Duke would be required to remove all coal ash from unlined pits at two plants - one along Lake Catawba near Charlotte, the other outside of Asheville. The changes would also call for Duke to dewater and close coal ash ponds at Lake Sutton (outside of Wilmington).

The CEO of Duke Energy sent a letter this week to Governor Pat McCrory and the Department of Environment and Natural Resources (DENR) outlining the company's plans for coal ash clean-up in the state.

Duke says the letter is a big deal.

DENR described it as inadequate.

A group of elected Democrats will detail their plans for the clean-up of coal ash Thursday afternoon in Raleigh. Democrat Pricey Harrison of Guilford County has introduced legislation a half dozen times to require the clean up of the potentially toxic coal ash at 14 Duke Energy-owned sites around the state. Her efforts have never advanced through the legislature.

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.
