Hurricane could flood many waste sites, creating toxic brew

Nearly three feet of water still covers the streets in Princeville, N.C., Sunday, Sept. 26, 1999. Floodwaters from Hurricane Floyd have begun to recede in the town that for more than a week has been completely submerged. Although water continues to recede Sunday, many rivers remain above flood stage and some are not expected to drop below that point until Friday. Light showers and thunderstorms are forecast for Monday. [/Michael S. Green | AP file photo]

The heavy rain expected from Hurricane Florence could flood hog manure pits, coal ash dumps and other industrial sites in North Carolina, creating a noxious witchesí brew of waste that might wash into homes and threaten drinking water supplies.

Computer models predict more than 3 feet of rain in the eastern part of the state, a fertile low-lying plain veined by brackish rivers with a propensity for escaping their banks. Longtime locals donít have to strain their imaginations to foresee what rain like that can do. Itís happened before.

In September 1999, Hurricane Floyd came ashore near Cape Fear as a Category 2 storm that dumped about 2 feet of water on a region already soaked days earlier by Hurricane Dennis. The result was the worst natural disaster in state history, a flood that killed dozens of people and left whole towns underwater, their residents stranded on rooftops.

The bloated carcasses of hundreds of thousands of hogs, chickens and other drowned livestock bobbed in a nose-stinging soup of fecal matter, pesticides, fertilizer and gasoline so toxic that fish flopped helplessly on the surface to escape it. Rescue workers smeared Vickís Vapo-Rub under their noses to try to numb their senses against the stench.

Florence is forecast to make landfall in the same region as a much stronger storm.

"This one is pretty scary," said Jamie Kruse, director of the Center for Natural Hazards Research at East Carolina University. "The environmental impacts will be from concentrated animal feeding operations and coal ash pits. Until the system gets flushed out, thereís going to be a lot of junk in the water."

North Carolina has roughly 2,100 industrial-scale pork farms containing more than 9 million hogs ó typically housed in long metal sheds with grated floors designed to allow the animalsí urine and feces to fall through and flow into nearby open-air pits containing millions of gallons of untreated sewage.

During Floyd, dozens of these lagoons either breached or were overtopped by floodwaters, spilling the contents. State taxpayers ended up buying out and closing 43 farms located in floodplains.

To prepare for Florence, the North Carolina Pork Council says its members have pumped down lagoon levels to absorb at least 2 feet of rain. Low-lying farms have been moving their hogs to higher ground.

"Our farmers and others in the pork industry are working together to take precautions that will protect our farms, our animals and our environment," said Brandon Warren, the pork councilís president and a hog farmer. "The preparations for a hurricane began long before the past few hours or days. Our farmers take hurricane threats extremely seriously."

The Environmental Protection Agency said Tuesday that it would be monitoring nine toxic waste cleanup sites near the Carolinas coast for potential flooding. More than a dozen such Superfund sites in and around Houston flooded last year in the aftermath of Hurricane Harvey, with spills of potentially hazardous materials reported at two.

Also of concern are more than two dozen massive coal ash pits operated by Duke Energy, the stateís primary electricity provider. The gray ash that remains after coal is burned contains potentially harmful amounts of mercury, arsenic and lead.

Since power plants need vast amounts of water to generate steam, their unlined waste pits are located along lakes and rivers. Some of the pits were inundated during past storms, including during Floyd and Hurricane Matthew in 2016.

After a 2014 spill at a Duke plant coated 70 miles of the Dan River in toxic gray sludge, state regulators forced the Charlotte-based company to begin phasing out its coal ash pits by 2029. Because that work was already underway, wastewater levels inside the ash ponds have been falling, Duke Energy spokesman Bill Norton said Tuesday.

"Weíre more prepared than ever," said Norton, adding that crews will be monitoring water levels at the pits throughout the storm.

The company is also preparing for potential shutdown of nuclear reactors at least two hours before the arrival of hurricane-force winds. Duke operates 11 reactors at six sites in the Carolinas, including the Brunswick Nuclear Plant located south of Wilmington near the mouth of the Cape Fear River.

The Brunswick plantís two reactors are of the same design as those in Fukushima, Japan, that exploded and leaked radiation following a 2011 earthquake and tsunami. Following that disaster, federal regulators required all U.S. nuclear plants to perform upgrades to better withstand earthquakes and flooding.

Duke Energy did not respond to requests for information about specific changes made at Brunswick, other than to say emergency generators and pumps will remove stormwater at the plant if it floods. The company issued assurances this week that it is ready for Florence, which is predicted to pack winds of up to 140 miles per hour and a 13-foot storm surge.

"They were safe then. They are even safer now," said Kathryn Green, a Duke spokeswoman, referring to the post-Fukushima improvements. "We have backups for backups for backups."
