WASHINGTON — The U.S. Environmental Protection Agency on May 11 proposed new carbon pollution standards for coal and gas-fired power plants to protect public health and reduce harmful pollutants.

EPA’s proposed standards are expected to deliver up to $85 billion in climate and public health benefits over the next two decades and avoid up to 617 million metric tons of total carbon dioxide (CO₂) through 2042.

EPA estimates that in 2030 alone, the proposed standards will prevent more than 300,000 asthma attacks; 38,000 school absence days; 1,300 premature deaths; 38,000 school absence days; and 66,000 lost work days.

Dr. Stephen A. Smith, Executive Director of Southern Alliance for Clean Energy: “Individuals and communities across the country are doing whatever they can to protect against the immense dangers of climate pollution and are depending on the federal government to do the same. Federal limits on climate pollution from power plants are a critically needed and long overdue protection for public health and the environment. 

“We will be reviewing the proposal and hope that the proposal hits the mark in giving our communities the safeguards they need from deadly fossil pollution.”

EPA will be taking comments on these proposals for 60 days after publication in the Federal Register.

WALLAND — The University of Tennessee Institute of Agriculture will host a demonstration of its new robotic milking technology at the UT AgResearch and Education Center’s Little River Unit in Blount County. The new system, developed by the Lely Corporation in the Netherlands, allows for the cows to be automatically milked at their own will in a stress-free environment. The demonstration is set for 10 a.m. May 2 and will include remarks from prominent university and community leaders.

The cows are trained to walk up to the robotic system, where each animal will be recognized by a sensor on its collar. The system then knows how much feed to give the cow while she’s being milked, based on historical data. The cow is free to eat, drink and rest while being milked, and in an area where there’s less cattle traffic. About 120 dairy cows can be milked and individual records kept through two robotic systems in a relatively short amount of time.

“The mission of UT AgResearch is to conduct leading-edge projects to serve the evolving needs of the agriculture and forestry industry in Tennessee and beyond,” said Hongwei Xin, dean of UT AgResearch.

“The introduction of milking robots into our existing traditional dairy production system at the Little River dairy facility allows our researchers to find answers to questions ranging from interactions between the animals and robots, impact on the animal’s production performance, and labor savings and profitability. The robotic milking system is part of the UT Precision Livestock Farming (PLF) initiative that aims to improve production efficiency and food supply chain robustness through enhanced animal welfare. UTIA is poised to be the leader in PLF in the region, the nation and the world.”

The big brown bat feeds on beetles, flies, moths, and true bugs, which it catches and eats while in flight. It is widespread across the Southern Appalachians and forages for food by flying slow, straight courses over water, forest canopies, wooded clearings, and around city lights.  J. Scott Altenbach via Georgia Department of Natural Resources

North America’s first State of the Bats report gives a sobering outlook for the winged mammals. According to the North American Bat Conservation Alliance report:

• More than half of the 154 known bat species on the continent could face severe population declines over the next 15 years.
• During that time, up to 82 percent of bat species will be negatively affected by climate change, especially extreme drought and temperatures.
• The scope and severity of threats — including habitat loss, wind turbines and the deadly bat disease white-nose syndrome — are increasing.

The news isn’t all bad. The report outlines ways to help and emphasizes the wide-ranging benefits of bats, from improving crop yields to eating insect pests. It also highlights the promise of focused, collaborative conservation efforts.

Case in point, the lesser long-nosed bat was once endangered in Mexico and the U.S. But thanks to international efforts, it is now delisted and recovered in both countries.

The North American Bat Conservation Alliance is another example. The coalition involving the U.S., Mexico and Canada created the 2023 State of the Bats report with Bat Conservation International and others.

“Bats face many challenges and the conservation landscape is increasingly complex,” said Dr. Jeremy Coleman, alliance co-chair and white-nose syndrome coordinator for the U.S. Fish and Wildlife Service. “While there is more to do, the level of international collaboration we have achieved for bat conservation in North America is a bright spot and a cause for optimism going forward.”

OAK RIDGE — The Center for Bioenergy Innovation has been renewed by the Department of Energy as one of four bioenergy research centers across the nation to advance robust, economical production of plant-based fuels and chemicals. CBI, led by Oak Ridge National Laboratory, is focused on the development of nonfood biomass crops and specialty processes for the production of sustainable jet fuel to help decarbonize the aviation sector.

The DOE announcement provides $590 million to the centers over the next five years. Initial funding for the four centers will total $110 million for Fiscal Year 2023. Outyear funding will total up to $120 million per year over the following four years, contingent on availability of funds.

“To meet our future energy needs, we will need versatile renewables like bioenergy as a low-carbon fuel for some parts of our transportation sector,” said U.S. Secretary of Energy Jennifer M. Granholm. “Continuing to fund the important scientific work conducted at our Bioenergy Research Centers is critical to ensuring these sustainable resources can be an efficient and affordable part of our clean energy future.”

KNOXVILLE — Knox County Mayor Glenn Jacobs is observing Women’s History Month throughout March by sharing videos each Wednesday highlighting time spent in different Knox County Schools’ Science, Technology, Engineering, Art and Math (STEAM) classrooms taught by female teachers.

The March 15 video features a visit with South Doyle High School STEM/Computer Science and 2022 KCS Secondary Teacher of the Year Katie DeVinney who was teaching a class on the principles of advanced manufacturing and practical design. 

“I hope out of courses like this, that young women are able to see the opportunities available in sectors of the economy like advanced manufacturing and hopefully pursue those,” Jacobs said in a press release.

DeVinney is a 10-year educator who began her career as a foreign language instructor but was inspired by her husband who started the Robotics program at South Doyle High School, to switch paths. 

“I just love it. It’s so much fun to see the excitement in kids when they get to take something that they designed on this computer and then hold it in the real world. It’s the coolest process I have ever seen so that’s kind of why I do it.” DeVinney said. 

Mayor Jacobs said celebrating women in STEAM is important for young girls because it shows them that women can succeed in technical fields — industry typically driven by men.

The mayor has already shared his visit with Hardin Valley Elementary STEM Educators Jessica Everitt and Jana Yra and his visit with West Valley Middle science teacher Bethany Saunders.

Later this month, he will share visits with Gibbs Middle School Art Teacher Dorothy Verbick and STEM Teacher Lauren Downs; as well as Karns Middle School Math Teacher Rebecca Layton.

OAK RIDGE — For the month of April 2023, the exhibition can bee seen, Thursdays and Fridays from 10 a.m. to 2 p.m. and Saturdays from 10 a.m. to 3 p.m., at the Oak Ridge History Museum, which is housed in the Midtown Community Center at 102 Robertsville Road, Oak Ridge, TN. That building itself is a significant landmark of Oak Ridge history. Constructed 1944-45, it has been used as a bathhouse and laundry, a hangout for students, a senior center, the Oak Ridge Convention & Visitors Bureau, and office of the Oak Ridge Heritage and Preservation Association. Many long-term Oak Ridgers refer to it simply as the ”Wildcat Den,” harking back to the time it was home base of the high school’s football team, the Oak Ridge Wildcats that were national champions in 1958.

NORRIS — The W. G. Lenoir Museum in Norris Dam State Park will be hosting “HerStory: A Photography Exhibition of Women in the Secret City.” The exhibit will open on March 1, and  be on display through the month in honor of Women’s History Month.

Constructed by the Civilian Conservation Corps (CCC) and opened in May 1936, Norris Dam State Park was managed by the Tennessee Valley Authority for 18 years prior to becoming a Tennessee State Park in 1953. Oak Ridge’s selection for the Manhattan Project was, in part, due to rural electrification that Norris Dam accomplished.

During the early 1940s, the park was closed to the public and the CCC vacation cottages winterized to house Manhattan Project workers. Later serving as a popular recreation destination for the growing government town, Norris Dam State Park continues to attract visitors from throughout the region. The construction of Norris Dam and Oak Ridge necessitated the relocation of countless families of the Clinch River valley by the federal government. These historical events connect these parks, and this new partnership will strive to tell the full stories of these places.

From janitors to homemakers and chemists, the women of the Manhattan Project worked hard and talked little. During WWII, Oak Ridge was a government town of 70,000 workers; primarily women who lived in a camp-like environment of barbed wire, security checkpoints, and code words. Workers were fingerprinted, interviewed, assigned a job, and given a clearance badge. Housing was limited and cramped and often unheated. Food at the cafeterias was in short supply and lines were long.   

The photographs were taken by James Edward Westcott, a renowned photographer who worked for the U.S. government in Oak Ridge during the Manhattan Project and the Cold War. Westcott was one of the few people permitted to have a camera in the Oak Ridge area during the Manhattan Project. For more information call the Manhattan Project National Historical Park at (865) 482-1942.

NYT: Decades of extraction have left the South American rainforest at a “tipping point.”

The Amazon has long served as a vast carbon sink, even as vegetation pumped oxygen into the atmosphere to the point it was called the “lungs of the Earth.”

But vast deforestation, despite calls to save the Amazon that originated decades ago, portends profound changes in the ecology of the huge, increasingly fragmented forest that lies mainly within Brazil.

“Just in the past half-century, 17 percent of the Amazon — an area larger than Texas — has been converted to croplands or cattle pasture. Less forest means less recycled rain, less vapor to cool the air, less of a canopy to shield against sunlight,” according to a report from Alex Cuadros.

“In one study, a team led by the researcher Paulo Brando intentionally set a series of fires in swaths of forest abutted by an inactive soy plantation. After a second burn, coincidentally during a drought year, one plot lost nearly a third of its canopy cover, and African grasses — imported species commonly used in cattle pasture — moved in.”

TOWNSEND — Smokies recovery teams on Monday found the body of Carl Keaney, 61, of Knoxville, in the Little River.

Keaney was last seen kayaking the Sinks during high flow when he vanished under water, prompting calls to Great Smoky Mountains National Park rangers who, along with other local crews, proceeded to search for his body for three days.

Here’s the previous Hellbender Press report:

Teams are searching for a missing kayaker in what Great Smoky Mountains National Park officials are now calling a “recovery operation” after a 61-year-old man disappeared underwater while boating above the Sinks on Little River. High water levels from recent heavy rains are making search and recovery difficult.

“Around 3:40 p.m. on Friday, Dec. 16 Great Smoky Mountains National Park dispatch received a call that a 61-year-old man had disappeared underwater while kayaking above The Sinks and did not resurface,” according to a news release from the park. 

Commercial air tour routes over Great Smoky Mountains National Park

GATLINBURG — Great Smoky Mountains National Park and other federal officials completed a management plan to formally regulate aircraft tours over the park.

Don’t expect much to change in the skies over the park: The plan allows 946 air tours a year by select helicopter operators, unchanged from the average number of annual flights recorded from 2017 to 2019. Flights may only operate from two hours after daybreak to two hours before sundown.

“The plan establishes measures to protect park resources including natural and cultural resources, preservation of wilderness character, and visitor experience,” according to Smokies officials. Flights will be restricted to six routes over the park, and must maintain an elevation above 2,700 feet of the highest terrain. Cades Cove is off limits, as are several historical sites, including the Walker Sisters Cabin.

Air tours, often to the dismay of many hikers and others, have occurred over the park for most of its history, but no formal flight guidelines were in place.

“We appreciate the tireless work that went into the development of the Smokies air tour management plan,” said Superintendent Cassius Cash. “The plan incorporates several improvements that allow continued air tour activity, while at the same time better protecting the wilderness character of the backcountry, wildlife populations, natural soundscapes, and the visitor experience in historic areas like Cades Cove.”

Eastern Band of Cherokee Indian members provided notable input into the development of the plan, which will go into effect in 90 days from Dec.3.

Hellbender Press previously reported on development of the Smokies aircraft management plan.

Nature Conservancy: Keep it real

Nothing beats the fresh aroma of a live Christmas tree, if you are into that kind of thing, but both real and fake trees carry their own load of sustainability pros and cons.

Live trees offer holiday beauty and scent and are a traditional addition to households. But they are harvested from a vast monoculture and require multiple levels of carbon-burning transport.

Artificial trees offer convenience, and can be reused for a decade. But they are largely made of plastic, manufactured in places with unsavory human rights records, and require global transit.

This article breaks it down pretty well. Maybe it’s just best to not have a Christmas tree?
