Buck Steam Station among Duke sites cited for leaking wastewater

Coal ash ponds at 12 Duke Energy facilities across North Carolina, including Buck Steam Station, are leaking wastewater, according violations issued Friday by state regulators.

The N.C. Department of Environmental Quality notified Duke Energy of unauthorized leaks at 12 of the company’s 14 coal-fired power plant sites. As a result, state officials are considering civil penalties. DEQ officials gave Duke 30 days to respond to violations at coal ash ponds.

Wastewater mentioned in the violations contains toxic levels of heavy metals. However, a statement issued by Duke Energy said the leaks aren’t new.

“Even the state environmental regulator acknowledges that seeps occur at every earthen impoundment, and those at ash basins are not impacting water quality,” the company said in its emailed statement.

Duke also cited a number of steps it’s currently taking to close coal ash basins, which is required by the 2014 coal ash management act.

“We are doing everything the state has asked to address seeps, including cataloguing, testing and monitoring them,” the company said. “Nearly two years ago, the company included seeps in permit applications to the state and has been working through the process ever since.”

DEQ spokesman Mike Rusher said seeps do occur at earthen dams. Rusher, however, said “ideally there wouldn’t be any seeps.”

The violations come as state officials are finalizing priority levels for closure of Duke Energy’s coal ash ponds. State officials have scheduled public meetings around North Carolina to gather input on priority levels, and the meeting for Buck Steam Station will be Feb. 22 at Catawba College’s Center for the Environment in Salisbury. Buck Steam Station has received a preliminary, low-to-intermediate priority ranking. It’s unclear whether Friday’s violations will affect the rating.

Attorneys from the Southern Environmental Law Center say the violations and potential fines are too little and too late.

“Citizen conservation groups and SELC brought illegal discharges to DEQ’s attention three years ago, yet it has take DEQ three years to take this proposed action,” attorney Frank Holleman said in an emailed statement. “But still, at many of these sites, DEQ is only proposing to issue fines.”

Holleman said fines won’t protect the public from pollution because Friday’s letters don’t require that coal ash be removed. In Buck Steam Station’s case, coal ash could be left in coal ash ponds near the Yadkin River and capped in place.

“It is way past time for DEQ to do its job, not treat any community as a low priority,” Holleman said.

Southern Environmental Law Center attorney Myra Blake added that Friday’s violations should be used as evidence for Buck Steam Station’s upgrade to a high priority site.

“According to Duke’s own assessments, the seeps at Buck are discharging 70,000 gallons per day,” Blake said. “Yet, DEQ did not consider this seepage in the so-called key factors that it relied on in its proposed prioritization decision at Buck.”

Despite the numerous, nearby residential wells declared unsafe for consumption, leaks at Buck Steam Station don’t cause exceedances in water quality standards, according to state officials. For it’s part, Duke Energy says the seeps don’t exceed water quality standards because the flow of wastewater is low.

In January, DEQ Assistant Secretary Tom Reeder said all seeps are different, but there’s a “very, very, very low potential” for wastewater to affect water quality.

To be clear, Duke Energy already discharges water. Friday’s violations are for leaks that haven’t been authorized by state regulators. At Buck Steam Station for example, A three-pond system slowly seaprates any coal ash constituents from water before discharge into the Yadkin River.

Mike Rusher, a spokesman for DEQ, said Friday’s violations aren’t directly linked to a cleanup process required by the 2014 Coal Ash Management Act. As part of the act, all coal ash ponds in North Carolina will be given a rating and prioritized for cleanup. A high-priority rating requires the company to excavate ponds. A low-priority rating allows Duke to cap coal ash in place.
