Duke Energy announced plans for its future coal ash cleanup efforts. But the fates of several coal ash sites threatening North Carolina communities remain unclear.

On Tuesday, Duke Energy announced it plans to excavate coal ash from ponds at three power plant sites in North Carolina, along with two more at its South Carolina facilities.

But the fates of several sites that pose significant threats to drinking water and nearby communities remain unclear.

Duke is already required by North Carolina’s Coal Ash Management Act to clean up four sites deemed “high-priority” by lawmakers. By recommending additional sites be excavated, Duke is committed to cleaning up ponds at seven of its 14 power plants across the state. That is, as long as the N.C. Department of Environment and Natural Resources is on board.

The total amount of coal ash now planned for excavation is 35.4 tons of ash. Duke plans to move the excavated ash to lined landfills or use it as structural fill material.

Although the company has now committed to cleaning up the ash at half of the sites in North Carolina, the majority of the ash polluting the state’s waterways remains largely unaddressed. As for the seven sites not included in today’s announcement, the company says further environmental testing is needed to assess contamination and determine clean up plans.

Importantly, the sites Duke has not committed to excavating are the largest in the state, including the 12.5 million tons of ash at Belews Creek, the 11.5 million tons at G.G. Allen, and the 27 million tons of coal ash stored at the Buck and Marshall plants. That amounts to more than 70 million tons — the bulk of Duke’s coal ash — still sitting in leaking, unlined ponds seeping and discharging into our waterways.

Around these unaddressed sites, nearly 500 households have been warned by the N.C. Department of Health that their well water is unsafe for drinking or to use for cooking due to contamination possibly associated with nearby coal ash ponds.

While Duke’s announcement is welcome news for the communities living near Moncure, Goldsboro, Lumberton and those who rely on the Cape Fear, Neuse and Lumber rivers for drinking water, others worry they’re being left behind and are concerned about potential harm caused by coal ash stored in landfills — and who is responsible for it.

A year and a half after the Dan River spill, Duke is certainly taking steps in the right direction. But there is still much work to be done for the company to prove it is the “good neighbor” it claims to be.

As the company’s coal ash cleanup efforts expand, we have just a few questions: Does Duke plan to leave more than 70 million tons of toxic ash in unlined ponds polluting North Carolina’s waterways? Will the company ensure the health and safety of workers and residents throughout the clean up process?

Until Duke makes an announcement that takes into account the safety of all its current and future neighbors, we’ll hold our applause.
