Duke Energy Cooling Pond Dam Collapses in Wake of Hurricane Matthew Flooding
[This breaking news is an update to a post earlier today on EcoWatch: Millions of Chickens Feared Dead at Factory Farms in Wake of Hurricane Matthew]
Waterkeeper Alliance and Upper Neuse Riverkeeper are responding to and documenting the breach of a 1.2-billion-gallon cooling pond dam at Duke Energy's H.F. Lee plant.
The breach occurred today just minutes after Duke Energy issued a statement claiming that the "Ash basin and cooling pond dams across the state continue to operate safely; in fact, we've been pleased with their good performance during the historic flooding Hurricane Matthew brought to eastern North Carolina."
Pete Harrison, staff attorney at Waterkeeper Alliance, and Matthew Starr, Upper Neuse Riverkeeper, released the following statement:
"When families are being threatened by some of the worst flooding in North Carolina's history, they should not also have to worry about Duke Energy's dams collapsing.
"This failure likely happened because the river has begun to recede, which is when structural problems often develop. Like so many of Duke Energy's coal ash ponds across the state, the cooling pond at Lee has a long history of structural problems—these are disasters waiting to happen.
"Minutes before the dam collapsed on the cooling pond, Duke Energy issued a statement declaring it was operating safely. Duke continues to claim the dam of a 120-acre coal ash pond at Lee is operating safely, even though the river has only begun to recede. The same ash pond suffered extensive damage after flooding caused by Hurricane Floyd in 1999. We remain very concerned about the integrity of the ash pond dams at Lee as the river recedes over the next week.
"It has been more than two years since the Dan River disaster, and Duke's coal ash continues to sit behind rickety dams on the banks of flood-prone rivers all across the state. Three ash ponds at the Lee plant, totaling 160 acres, have been completely submerged since Sunday."
In response to Waterkeeper Alliances breaking news, Greenpeace organizer Caroline Hansley said:
"Duke Energy can attack environmental groups all it wants, but the fact remains that it is misleading the public and the people of North Carolina about the safety of its dams, and Governor McCrory is letting the company get away with it- again. As the flood waters from the devastating Hurricane Matthew recede, we need a Governor who will put people's safety and access to clean drinking water before the interests of his previous employer, Duke Energy.
"Duke Energy has a terrible track record when it comes to protecting the safety of North Carolina's waterways and drinking water. In the two years since the Dan River coal ash disaster, Duke Energy has fought efforts to clean up leaking coal ash pits which threaten the health and safety of nearby communities. Instead of cleaning up its hazardous messes, Duke uses its political influence with its previous employee, Governor McCrory, allowing the company to leave 70 percent of its toxic coal ash leaking across the state.
"Hurricane Matthew proves again that Governor McCrory will always put corporate interests before the people of North Carolina."

Farms with just one or a handful of different crops encourage fewer species of pollinating and pest-controlling insects to linger, ultimately winnowing away crop yields, according to a new study.
Up to half of the detrimental impacts of the "landscape simplification" that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects, a team of scientists reported Oct. 16 in the journal Science Advances.

"Our study shows that biodiversity is essential to ensure the provision of ecosystem services and to maintain a high and stable agricultural production," Matteo Dainese, the study's lead author and a biologist at Eurac Research in Bolzano, Italy, said in a statement.
It stands to reason that, with declines in the sheer numbers of insects that ferry pollen from plant to plant and keep crop-eating pests under control, these services will wane as well. But until now, it hasn't been clear how monocultures affect the number and mix of these species or how crop yields might change as a result.
Aiming to solve these questions, Dainese and his colleagues pulled together data from 89 studies cutting across a variety of landscapes, from the tropics of Asia and Africa to the higher latitudes of northern Europe. They tabulated the number of pollinating and pest-controlling insects at these sites — both the absolute number of individuals and the number of species — along with an assessment of the ecosystem services the insects provided.
In almost all of the studies they looked at, the team found that a more diverse pool of these species translated into more pollination and greater pest control. They also showed that simplified landscapes supported fewer species of service-providing insects, which ultimately led to lower crop yields.
The researchers also looked at a third measure of the makeup of insect populations — what they called "evenness." In natural ecosystems, a handful of dominant species with many more individuals typically live alongside a higher number of rarer species. The team found as landscapes became less diverse, dominant species numbers dwindled and rare species gained ground. This resulting, more equitable mix led to less pollination (though it didn't end up affecting pest control).
"Our study provides strong empirical support for the potential benefits of new pathways to sustainable agriculture that aim to reconcile the protection of biodiversity and the production of food for increasing human populations," Ingolf Steffan-Dewenter, one of the study's authors and an animal ecologist at the University of Würzburg in Germany, said in the statement.
The scientists figure that the richness of pollinator species explains around a third of the harmful impacts of less diverse landscapes, while the richness of pest-controlling species accounts for about half of the same measure. In their view, the results of their research point to the need to protect biodiversity on and around crops in an uncertain future.
"Under future conditions with ongoing global change and more frequent extreme climate events, the value of farmland biodiversity ensuring resilience against environmental disturbances will become even more important," Steffan-Dewenter said.

Greenland had quite the summer. It rose from peaceful obscurity to global headliner as ice melted so swiftly and massively that many were left grasping for adjectives. Then, Greenland's profile was further boosted, albeit not to its delight, when President Trump expressed interest in buying it, only to be summarily dismissed by the Danish prime minister.
During that time I happened to be in East Greenland, both as an observer of the stark effects of climate change and as a witness to local dialogue about presidential real estate aspirations, polar bear migrations and Greenland's sudden emergence as a trending topic.

Heavy metals that may damage a developing brain are present in 95 percent of baby foods on the market, according to new research from the advocacy organization Healthy Babies Bright Futures (HBBF), which bills itself as an alliance of scientists, nonprofit organizations and donors trying to reduce exposures to neurotoxic chemicals during the first three years of development.

Creepy-crawlies are among the oldest life forms on this planet. Before dinosaurs ever walked the earth, insects were certainly already there. Some estimates date their origins to 400 million years ago. They're also extremely successful. Of the 7 to 8 million species documented on Earth, around three quarters are likely bugs.
But several insect species could disappear for good in the next few decades and that would have serious consequences for humans.
