CHARLOTTE, N.C. – Duke Energy was in a bind.
North Carolina regulators had for years allowed the nation’s largest power company to pollute the ground near its plants without penalty. But in early 2013, a coalition of environmental groups sued to force Duke to clean up nearly three dozen leaky coal ash dumps spread across the state.
So last summer, Duke Energy turned to North Carolina lawmakers for help.
Documents and interviews collected by the Associated Press show how Duke’s lobbyists prodded Republican legislators to tuck a 330-word provision in a regulatory reform bill running nearly 60 single-spaced pages. Though the bill never once mentions coal ash, the change allowed Duke to avoid any costly cleanup of contaminated groundwater leaching from its unlined dumps toward rivers, lakes and the drinking wells of nearby homeowners.
Passed overwhelmingly by the GOP-controlled legislature, the bill was signed into law by Gov. Pat McCrory, a pro-business Republican who worked at Duke for 28 years.
“For decades, Democrats have stifled small businesses and job creators with undue bureaucratic burden and red tape,” McCrory said at the time. “This common-sense legislation cuts government red tape, axes overly burdensome regulations, and puts job creation first here in North Carolina.”
Environmentalists saw the legislation, and its little-noticed provision benefiting Duke, differently.
“This sweeping change gutted North Carolina’s groundwater law,” said D.J. Gerken, a senior attorney for the Southern Environmental Law Center.
The level of coordination between Duke and North Carolina’s lawmakers and regulators had long been of concern to environmentalists. But when a Duke dump ruptured on Feb. 2 – spewing enough coal ash to coat 70 miles of the Dan River with toxic sludge – the issue took on new urgency.
Federal prosecutors have launched a criminal investigation into the spill, issuing at least 23 grand jury subpoenas to Duke executives and state officials.
The first batch of subpoenas were issued the day after an AP story raised questions about whether North Carolina regulators had helped shield Duke from a coalition of environmental groups that wanted to sue under the U.S. Clean Water Act to force the company to clean up its coal ash pollution.
Still, regulators alone could not protect the company from its huge liability if the environmental groups persevered in court. So Duke officials lobbied – successfully – to change state law.
Their vehicle was the Regulatory Reform Act. And they took aim at a provision that had been on the books for decades, requiring Duke to halt the source of contamination if its subterranean plumes of pollution crept more than 500 feet from its ash dumps.
North Carolina’s 14 coal-fired plants have 33 waste pits. Each is surrounded by a “compliance boundary,” with monitoring wells tracking the spread of underground pollution.
A compliance boundary is like an early warning system. If groundwater contamination inside the line exceeds state environmental standards, a company is supposed to take corrective action. The goal is to stop the spread of pollution to neighboring properties, as well as rivers and streams.
But that wasn’t happening. Instead of enforcing the limit, state officials were letting Duke continue to pollute groundwater inside its compliance boundaries around old ash pits without taking any action to stop the contamination. At some plants, regulators even let Duke redraw its compliance boundaries when it looked like contamination might cross the line, a stalling tactic to avoid the cost of cleanup.
Data collected from Duke’s own monitoring wells showed contamination beyond that 500-foot limit at several of its properties, with high levels of arsenic, selenium, lead and other poisonous contaminants found in coal ash.
After examining results from test wells at the ash sites, the Southern Environmental Law Center found that many exceeded state water-quality standards. Lawyers believed state officials were interpreting regulations to allow the company to profit rather than protect public health and the environment.
On behalf of Cape Fear River Watch, the Sierra Club, Waterkeeper Alliance and the Western North Carolina Alliance, the law center asked the state Environmental Management Commission to instruct the state to “interpret the groundwater protection rules as they were written.”
The environmental groups wanted the commission to order regulators to force coal-ash operators to take immediate corrective action when toxic chemicals in groundwater exceeded state water quality standards at or beyond the compliance boundary.
The commission ruled against them, so the environmental groups appealed in state court.
That’s when Duke’s lobbyists began reaching out to lawmakers.
George Everett, the director of environmental and legislative affairs for Duke, said the company wanted the law changed to “be consistent with the rules.”
Republicans took control of North Carolina’s legislature in 2010 for the first time since Reconstruction and cemented full control of state government with the inauguration of McCrory as governor last year. That put them in prime position to implement an ardently pro-business, anti-regulation platform.
Working closely with lawmakers, the lobbyists helped craft a provision to conform to the way state regulators had been interpreting the law. The change would allow Duke to contaminate groundwater until it crossed onto a neighbor’s property.
Duke Energy and its executives have donated millions in recent years to both Republicans and Democrats. Though 2013 was not an election year, records show the company continued to give generously as its lobbyists sought to protect its ash pits.
McCrory spokesman Josh Ellis insisted that the change in the law didn’t change anything at all.
He’s right: The compliance boundaries are still in the same place, but only because the state environmental agency has not yet drafted new rules to comply with the new law, as required.
“They are pretending that the law had nothing to say about the compliance boundary moving,” said Gerken, the environmental lawyer. “They’re wrong. It directed DENR to change the rules to be consistent with the law.”
