Varied environmental groups offer unified plea for clean energy, coal ash management and accountability from TVA
It was people power generating energy at Market Square in downtown Knoxville on Wednesday.
A coalition of civic and environmental groups and their representatives met at the bottom of the two Tennessee Valley Authority towers urging the public utility to reopen meetings to public comment; swear off all fossil fuels by 2030; and carefully tend to the needs of those affected by coal ash and devise a plan to contain it for the safety of current and future generations.

Lead is flying as bald eagles face ambush on road to full recovery
Written by Stephen Lyn Bales
This grounded bald eagle at a wildlife refuge in Missouri eventually succumbed to lead poisoning. Lead from bullets and shot are the latest threat to bald eagles, the recovery of which is an American conservation success story. Betty Thompson
Once again bald eagles are in trouble: This time the threats are a deadly recipe of lead and neurotoxins.
The recovery of America’s bald eagles is one of the greatest environmental success stories of the past 50 years. From an estimated overall population of about 800 at the depth of their decline, they have rebounded to about 100,000 today living near water in Alaska, Canada and all of the lower 48 states.
Hellbender Press has covered the success story that brought our national symbol, the bald eagle, back from the brink of extinction.
The cause of that long-ago calamity was ferreted out with the help of an early citizen-scientist, a retired Canadian banker living in Florida named Charles Broley, who became interested in eagles and obtained a permit to band eaglets. Between 1939 and 1946 he banded a total of 814 of them in the nest before they fledged.
As the years passed Broley observed a population decline and initially thought habitat loss was to blame. But in an Audubon article he penned in 1958, Broley concluded, “I am firmly convinced that about 80 percent of the Florida bald eagles are sterile.”
But why? Broley was the first to speculate that the use of organochlorine pesticides, most notably dichlorodiphenyltrichloroethane, or DDT for short, was somehow the cause; but he had no proof and didn’t know how the chemical compound actually affected adult eagles.
Broley’s suspicions and others were brought to national attention by Rachel Carson in her landmark 1962 book, “Silent Spring.” DDT was outlawed in 1972 and the eagle population slowly began to recover.
And today? Bald eagles still face problems — both old and new.
The old one is lead poisoning.
News Sentinel: Anderson County ball fields built atop TVA coal ash
News Sentinel: Toxic ash fill at Claxton ball field uncapped and unsealed
Tennessee Valley Authority used a mix of coal ash and dirt for fill during construction of a playing field that was later leased to Anderson County and the local Optimist Club for public use, reported Jamie Satterfield of the Knoxville News Sentinel.
She had earlier reported an adjacent playground was contaminated by coal ash byproducts, including heavy metals and multiple other toxins. The contaminants likely originated from coal-ash piles at the nearby Bull Run Fossil Plant.
Anderson County and the Claxton Optimist Club operate the playground and sports fields, which are still owned by TVA.
The playground was built about 20 years ago, during which time coal ash disposal was lightly regulated. The disposal of coal ash from facilities such as Bull Run coal plant, which will be closed by 2023, has proven a major environmental problem and challenge for utilities across the country.
Limbless bears break hearts but donuts may be worse than leg traps

By any other name: From poaching to cars and traps, black bears face diverse human threats in Southern Appalachians
Activists and state agencies agree bear poaching is an age-old problem in the mountains of Tennessee and North Carolina, but they diverge when it comes to some key aspects of the crime and its prevention.
The non-profit Help Asheville Bears is raising awareness of threats to bears on both sides of the state lines and getting coverage on local media outlets like this piece on Knoxville-based WBIR. Its message has also appeared on a billboard in Sevierville. The Arden, N.C.-based group offers a tip line, rewards and also supports what could be described as a self-styled anti-poaching militia.
“Bear poaching is a big deal. It happens anywhere where there are bears,” said Jody Williams, the founder of Help Asheville Bears, which is responding to what its members see as an increasing threat to the very symbol of wild Southern Appalachia. HAB is especially concerned about trapping that Williams said has left limbless bears limping throughout the mountains.

Report: Children exposed to coal-ash pollutants in Knoxville-area playground
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.”
The 17-year cicada brood left behind some calling cards in the trees
Written by Alexandra DeMarco

Tree “flagging” is a lingering sign of the 17-year cicadas’ brief time on Earth
(Alexandra DeMarco is an intern in ORNL’s media relations group.)
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.
Tell TVA: Don’t replace Kingston Coal with new fossil gas plants or pipelines!
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 sounds of silence: 17-year cicadas fade away as offspring prepare for 2038 performance

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.
Despite Covid slowdowns and shutdowns, Smokies draws $1B in 2020 revenue to neighboring communities

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.

Ijams posted record visitation during pandemic even as resources were challenged
(This is the second in an occasional Hellbender Press series about the effects of the Covid-19 pandemic on the natural world. Here's the first installment about air quality improvements in the Smokies.)
Individuals and organizations can learn a lot from a pandemic.
You up your technology game. You innovate and run harder and get leaner. You realize the importance of face time (the real face time).
You learn the power of allies and those who really love you.
And in the case of Ijams Nature Center in South Knoxville, you learn just how much people need and value the natural world and the outdoors, especially in times of acute stress and uncertainty.
Ijams played host to a record number of visitors in 2020; there was no usual winter slowdown. Parking lots were full virtually every day during the height of the pandemic that claimed the lives of at least 600,000 people in the U.S. That visitation trend has continued at Ijams, with the coronavirus somewhat comfortably in the rear-view mirror.
An estimated 160,000 people visit the popular nature center annually, but there’s no exact count. Officials said the 2020 visitation substantially surpassed that number, and they plan a visitation study because a very “porous border” prevents an accurate count.
“The one great thing that has come out of Covid, is that people have recognized the importance of nature in their lives; they’ve recognized it as a place for solace, a place to get out and be safe and feel comfortable,” said Ijams Nature Center Executive Director Amber Parker.
“The sheer mass number of people coming were new to Ijams, or maybe come once or twice coming multiple times a week,” said Ijams Development Director Cindy Hassil.
“We were so excited to be this refuge for everyone,” Parker added.
The two women spoke on a sunny spring afternoon on the fetching expanse of stone terrace behind the visitors center in the shade of tulip poplars, red buds and dogwoods. Cardinals chirped and early 17-year cicadas throbbed behind a natural green curtain.

Is the bald eagle’s remarkable comeback fading down the stretch?
(Part one in a series)
It was a damp morning in early spring 2005 when Paul James and I met Linda Claussen at Seven Islands Wildlife Refuge along the French Broad River in east Knox County. Heavy rains had fallen through the night, but the clouds were beginning to break. As we walked down Kelly Lane toward the river the vocalized yearnings of thousands of chorus frogs could be heard singing from the soppy floodplain along the river. Spring was definitely here.
The refuge itself was the brainchild of Linda’s late husband, Pete. In the late 1990s, he formed the Seven Islands Foundation, a privately owned land conservancy, and began setting aside property to be protected and restored to a variety of natural habitats. Most of the acreage had recently been fescue pasture maintained for grazing livestock and hay production.

Loghaven: An award-winning natural and built environment in South Knoxville intends to get minds moving
Five years after he first saw the property that would become Loghaven Artist Residency, architect Brandon Pace was in one of the renovated cabins, listening to a performance by now-late composer Harold Budd, in town to perform at the 2019 Big Ears music festival.
The experience brought home the full potential of a truly special place.
“That was wonderful,” Pace said of that moment. “You could see it being a place for a composer. You saw this could be something. You could see how our city comes alive in events like this.”
This spring, Knoxville-based Sanders Pace Architecture was awarded a 2021 AIA Architecture Award for the design and architectural rehabilitation work at the 90-acre Loghaven property, which is owned and managed by the Aslan Foundation.
“The role they play in supporting good design in our community cannot be overstated,” Pace said of the Aslan Foundation.
Team member Michael Davis was awarded the 2021 AIA Young Architects Award.
On June 1, Loghaven Artist Residency opened up the application process for its second class of in-person residents, artists who work in visual, performing, literary, and interdisciplinary artistic fields.
“Save Loghaven”
Loghaven is a uniquely quirky part of Knoxville history. It began as a collection of log cabins in a heavily wooded area along Candora Road in South Knoxville.
The cabins were built as rental properties by single mom and entrepreneur Myssie Thompson in 1935, in the middle of the Great Depression. Her cabins, as well as one built by neighbor John Hightower, are the heart of the property.
Generations of UTK students and professors, young professionals, and others rented the alluring cabins. But by the late 1990s, the area was sinking into disrepair, with kudzu, privet, and other invasive plants growing up around the cabins and previously cleared areas.
