Chatham County officials have reached an agreement with Duke Energy on parameters of storing coal ash at a clay mine in the county.

A deal was struck between the county and the energy giant after weeks of negotiations, according to officials.

Chatham County Manager Charlie Horne says the county’s focus was getting the best arrangement it could with Duke.

“Given that, no matter what we do, we’re likely going to get coal ash,” he says, “what is the best deal, if you will, we can get from Duke Energy to do other things potentially in Chatham County.”

Duke Spokesperson Jeff Brooks says the company is happy both sides were able to reach an accord.

“We’re very pleased to have reached an agreement with local leaders that will provide positive benefits, we believe, to the people of Chatham County,” he says. “Duke Energy is very committed to being responsible and transparent as we move forward with our work at the Birckhaven mine and ensuring that the work that we do is done safely and with a focus on protecting the environment.”

Horne says the agreement puts forward the parameters of the coal ash that can be moved to Chatham County.

“The agreement provides for a limit of 12 million tons of coal ash disposal at the Brickhaven site in Moncure,” he says. “In return for that, we will get $1.50 per ton for that disposal up to 12 million tons.”

Lee County officials agreed to a similar deal with Duke Energy earlier this year to store coal ash.

It came to this stage of seeming inevitability for the county after the state Department of Environment and Natural Resources granted Duke the necessary permits to dispose of coal ash in the pits.

Brooks says the state is the ultimate rule maker in this scenario, but Duke would prefer to operate with cooperation of local government.

“Certainly the state law directs how we operate and how we move forward with this project, but we recognize that there’s an impact to the local community,” he says. “We recognize that, just from an operational standpoint, this will be something ongoing for several years in Chatham County.

“And we wanted to be fair to the local community. We wanted to find a solution that could provide positive benefits to the people of Chatham County.”

The ash will be stored dry, rather than in the lagoons it is currently stored in across the Tar Heel state.

The pits will be lined before the ash is placed into the pit and another layer of lining will be placed over the coal ash once it is in place, according to Duke.

Horne says the county is pleased no additional ash will be brought to the site of the Cape Fear Plant.

“The Cape Fear site, which was the old power plant, Duke Energy also agreed that there will be no coal ash stored there other than what’s already on the site,” he says. “We think that’s a plus.”

As part of the Coal Ash Management Act of 2014, Duke has to move coal ash from lagoons at four high-risk sites across North Carolina by 2019. Duke must move all of the coal ash from the 10 remaining sites by 2029.

Brooks says progress has been preliminary up to this point.

“We’re actually finalizing a lot of those plans,” he says. “We’ve announced some of them, obviously. We’re beginning the process of siting land fills at some of our plants that will be used for storing ash.

“We’ve begun moving ash from our Riverbend station to a location in Georgia that is accepting that material. And I think that you’re going to see over the next few months a lot of activity, a lot of new announcements on plans and other work that’s being done.”

Brooks says the nation’s largest electric utility is focused on meeting the deadlines laid out by the state.

“We believe we can meet the timelines. We are committed to complying with the law,” he says. “It’s going to be a herculean task, and it’s going to take a lot of work from many dedicated teams that are working throughout the company.

“But right now our focus is on meeting the requirements of the law and doing that in a responsible way.”

Before any coal ash can be moved to the pits in Chatham and Lee Counties, Duke Energy still needs approval from the federal government and the Army Corps of Engineers.

Brooks says that Duke is hopeful that late this summer or early this fall it will be able to begin work at the site in Chatham County.

County officials say the $18 million Duke will be providing the county in exchange for the storage will be used to monitor the environmental risks around the site. Commissioners have also asked for baseline testing to be done of water sources around the pits.
