News Sentinel: Playground near TVA’s Bull Run Fossil Plant contaminated by coal ash

Testing by independent Duke University researchers indicates a playground in the Claxton community contains dangerous levels of coal-ash byproducts.

The playground is near the Tennessee Valley Authority’s Bull Run steam plant, which has historically used vast amounts of coal to produce electricity and stored the resultant coal ash in huge landfills near the facility on Melton Hill reservoir near Oak Ridge. The plant will be decommissioned within two years, but questions remain about how TVA will handle the tons of remnant coal ash produced over the lifetime of the plant.

Duke University researchers sampled soil from the site, and results showed high levels of heavy metals and other toxins typically present in coal ash.

TVA maintains its testing has not detected harmful levels of contaminants in the area, but the News Sentinel’s Jamie Satterfield, who was been relentless in her investigations of TVA coal-ash policies and the disastrous Kingston coal slurry spill of 2008, noted that “There are no human health guidelines, however, for substances like coal ash that combine many toxins or radioactive metals.”

Here is some evidence of tree browning and “flagging” caused by the recent appearance of Brood-10 cicadas earlier this summer.  Courtesy Oak Ridge National Laboratory 

Tree “flagging” is a lingering sign of the 17-year cicadas’ brief time on Earth

On the road leading to the U.S. Department of Energy’s Oak Ridge National Laboratory, drivers may notice that many of the green trees lining the entrance to the lab are dappled with brown leaves. At first glance, the sight isn’t extraordinary, as deciduous tree leaves turn hues of oranges and browns before falling to the ground each autumn.

Yet, just weeks past the summer solstice, this phenomenon is out of place and is in fact evidence of another natural occurrence: cicada “flagging.”

This spring, Brood X cicadas emerged from the ground after 17 years and swarmed across the eastern United States, leaving a trail of exoskeletons and echoes of mating calls. Cicadas emerge in such large quantities to withstand predation and successfully maintain their populations, and trees actually play a key role in their life cycle.

A male cicada attracts a female through a mating call, the sound responsible for cicadas’ shrill hum. After the two mate, the female cicada uses a sharp tubular organ called an ovipositor to slit the bark and split the sapwood of young tree branches to deposit her eggs there. These incisions, however, damage a tree’s vascular system and can cause stalks beyond the incision to die and wither, leaving behind twigs with brown leaves that resemble flags dangling from the trees.

The eggs then grow into nymphs that make their way to below ground. An oft-repeated misconception is that they’ll stay dormant for 17 years. Actually, during that time, they go through 5 life stages while feeding on the xylem (tree sap) of roots. This may further weaken saplings that were heavily infested with cicadas.

Remember TVA’s 2008 Kingston Fossil Plant coal fly ash slurry spill

The Tennessee Valley Authority plans to retire the Kingston plant and its four other remaining coal-fired power plants by 2035.

But it is seriously considering replacing them with large fossil gas power plants and new gas pipelines!

Natural gas is cleaner than coal, but is yet another fossil fuel source that releases carbon dioxide. Such a replacement would be contrary to the national and global consensus that we must reduce the use of fossil fuels quickly to constrain the runaway climate crisis as much as we can.

A plan based on emerging technologies for increased energy efficiency combined with distributed use of renewable energies and energy storage can increase community resilience; create more good, long-term jobs; diversify local business opportunities; and provide immediate public health benefits.

The cicada soundtrack of spring and early summer has come to a quiet end

“Turn out the lights, the party’s over,” sings country music outlaw Willie Nelson. “They say that all good things must end.”

Yes. Essentially Cicadapalooza 2021 is over. There may be a few late emerging males hanging on like the last few guys in the bar at closing time with hope against hope that somehow they will get lucky and Miss Wonderful will walk through the door. In this case, a female 17-year cicada clicks and clicks to let the male know she is interested or desperate to complete her mission.

As a rule of thumb, the entire periodical cicada phenomenon lasts four to six weeks but it is extremely weather dependent. Insects are ectothermic and need warm to hot temperatures to be active.

I saw my first evidence the cicada emergence had begun at Ijams Nature Center, where I worked for 20 years as a naturalist. Executive director Amber Parker told me where to look for emergence holes: under the sugar maple at the back of the Universal Trail. That was on April 20. I found the small exit tunnels but no cicadas or exuviae. I knew skunks, foxes, crows, jays, owls, dogs, cats, and anything else that will eat a bug quickly consume the first ones above ground.

Green begets green in Smokies region; Big South Fork and Cumberland Gap also economic players

Recent federal analysis of spending by national park visitors is a testament to the economic benefits of environmental protection, scientific study and outdoor recreation.

The 12.1 million visitors to Great Smoky Mountains National Park in 2020 spent $1.024 billion in neighboring communities in both Tennessee and North Carolina, according to a study released this week by the National Park Service. Similar, localized releases were distributed into national park communities across the country.

Closer to home, that number represents the estimated visitor money spent in areas that include traditional “gateway” communities, such as Townsend and Gatlinburg, and Cherokee and Bryson City in North Carolina. Regionally, it’s at least a $5 million increase since 2012. Travel problems, housing and employee shortages, overdevelopment and environmental destruction are of course persistent in some of those areas.
