Lake Norman-area residents to DEQ: Duke coal ash must go
Sheila Holman, assistant secretary of the the North Carolina Department of Environmental Quality, who often seems to draw the short straw when chosen to lead a public meeting, took a poll of the residents who had filled the Sherrills Ford Elementary School gymnasium to its 452-person capacity.
The questions involved how Duke Energy should dispose of the 16 million tons of coal ash currently percolating in an unlined impoundment at the Marshall Steam station on Lake Norman.
“How many of you prefer excavation?” Holman said.
Everyone raised their hand.
“How many of you prefer the hybrid?” — a combination of capping the impoundment and a smaller landfill.
“How many of you prefer to cap the impoundment?”
Again, no hands.
Confusion ensued. Originally, DEQ had planned for a science-fair type event, in which people would visit booths to learn about surface water, groundwater, dams and other aspects of the proposal.
But the crowd was having none of it. Two zip codes in Iredell County have higher than expected incidences of thyroid cancer. Although these cases have not been connected to contamination from coal ash — also used as structural fill beneath area shopping centers and an apartment complex — residents feel anxious. They wanted to speak — forcefully and in front of their peers. They wanted to learn from one another’s questions. On the fly, DEQ changed the meeting format. For nearly two hours, residents asked for answers, some of which the department representatives could not provide.
“Where has Duke sold its structural fill?” one man asked.
DEQ has documented some of structural fill projects throughout the state, Holman said, “but we’re asking Duke for their records.”
One exasperated man told state officials, “Anything short of excavation is unacceptable.”
Marshall plant an overwhelming presence in the community
Marshall announces itself with an cumulus cloud of steam flowing from stacks that tower above trees on the horizon. But not until you approach the plant on NC 150 do you comprehend its enormity. With metal coal conveyors crisscrossing the site and pollution scrubbers that resemble gigantic clothes dryer vents, the plant sits right along the highway. At rush hour, when the two-lane road is jammed, it can feel as if the plant could devour you.
Since 1965, Marshall has generated electricity by burning coal, and like most power plants, it needs water for cooling. Lake Norman provides that water. And the lake also attracts boaters, fishers and residents who want to live close to the water.
In the bleachers, residents shared stories with one another of life along the lake that they’ve shared with Duke Energy. “I used to tell my son when he’d go out on the boat to follow the steam” to lead him home, one woman said.
Another person’s neighbor dredged part of the shore to build a pier. “He dug up coal ash,” the resident said.
Duke Energy has proposed three options for disposing of the ash at Marshall:
- Excavate the material and move it to a landfill, either on- or off-site;
- Leave the ash in its unlined impoundment and cover it with a protective cap to minimize erosion and the infiltration of rainwater;
- A hybrid of both methods.
Whatever method DEQ approves, state law doesn’t require it to be completed until 2029.
Duke has often cited myriad reasons, such as cost and environmental issues involved in digging up tons of material, for opposing excavating ash from six of its 14 coal facilities. But it is possible, even at a site as large as Marshall.
It would require digging up and dewatering the material, much of which is now buried under trees, said Ed Mussler of the Division of Waste Management. Meanwhile, Duke would build a lined landfill onsite on the north end of the property and about a mile from the lake. Trucks would move the ash from one place to another. When finished, the landfill could tower 150 to 175 feet in the air. The entire process would take at least four years.
Georgia Power, said attorney Frank Holleman of the Southern Environmental Law Center, is removing all of the ash from a 21 million ton impoundment. And while Duke had initially planned to excavate none of its ash in North Carolina, litigation filed by Holleman’s group forced its hand, and now the utility is removing ash from impoundments at eight of its sites.
South Carolina has required Duke Energy to excavate its coal ash landfills. Indiana is prohibiting the ash from infiltrating groundwater. (Coal ash impoundments routinely contaminate groundwater because they aren’t lined. Duke’s own tests, required under federal law, show that groundwater beneath their plants is polluted with arsenic, radium, vanadium, boron and other chemicals.)
However, there is no legal mandate to excavate in North Carolina. After the Dan River spill in 2014, the legislature passed the Coal Ash Management Act, which allows Duke, if certain environmental thresholds are met — as determined by DEQ — to leave the ash in its unlined impoundments.
Victoria Eaves has lived on Lake Norman for 15 years. And for all of those 15 years, she said, she has driven to Concord to buy water because her home is on a private drinking water well.
“I’m terrified,” another woman, who lives on the Kiser Island section of Lake Norman, told state officials. “We’re all on wells.”
Currently, there is no evidence directly linking the thyroid cancers and the incidences of rare ocular melanomas in nearby Huntersville to coal ash. But Duke University scientist Heather Stapleton is working with Mooresville activist Susan Wind, whose teenage daughter developed thyroid cancer, to test drinking water and household dust in people’s homes. And Virginia Tech researchers have announced they will begin testing drinking water in Lake Norman neighborhoods, similar to a study they conducted in Robeson County.
State Rep. John Fraley, a Republican from Iredell County, and State Sen. Vickie Sawyer, who represents Iredell and Yadkin counties, both attended the meeting. (Fraley has received $3,000 in campaign contributions from Duke Energy since 2016, according to state records. Sawyer has not.)
Sawyer’s main home in Iredell County is near a structural fill site. The ash, she said, is “less than 2,000 feet from my well.” She also has a small house on Lake Norman. “At night I can hear the trains dumping coal. That’s how close I am,” she told the crowd. She also had her two daughters tested for thyroid cancer. “I’ve had people come to my house crying because they’re afraid.”
Although Sawyer was appointed to her seat only last year, she said she would take residents’ concerns to her fellow lawmakers. “We will not stop until we get answers,” she said.
