  Climate change could steal your fish

  CHEROKEE — The mountains of the Southern Appalachians were scraped clean a century ago. Headwater ecology changed as the canopy of trees disappeared that was shading the streams from all but the noonday sun. Rainstorms pushed dirt and rocks into the water muddying the feeding and breeding grounds of fish, amphibians and insects. 

  Lower down the mountain, newly cut pastures edged right up to the creeks while cows mucked up the once-pristine waters. Invasive bugs killed hemlocks, ash and other shade-giving trees. Pipes, culverts and dams blockaded streams and kept animals from cooler water. 

  The trout never had a chance.

  Now they face an even more insidious foe — climate change.

  OAK RIDGE — The northern corner here is a small place teeming with treasures, including the Worthington Cemetery Ecological Study Area.

  Elza Gate Park off Oak Ridge Turnpike, also known as Tennessee Highway 95, is the starting point for walking trails taking visitors through a cedar barren, a somewhat open habitat including eastern red cedars. The barrens include plants more similar to a prairie than many East Tennessee forests. The trail reaches a cemetery dating before the founding of Oak Ridge.

  Woven together in this small area there is a natural mix of wildlife and historical preservation. Visitors to the loop trail will encounter a pine forest and a wetland area complete with a boardwalk to observe birds. Tennessee Valley Authority designated the land as both an Ecological Study Area and Small Wild Area.

  WASHINGTON, D.C. — The green floater, a freshwater mussel native to the waters of Southern Appalachia, is now formally considered at risk of extinction due to the loss and fragmentation of its aquatic habitat. 

  The U.S. Fish and Wildlife Service determined the green floater, historically found in 10 eastern U.S. states, is likely to become endangered due to existing and emerging threats. The service is proposing to list the mussel as threatened under the Endangered Species Act. 

  The green floater is still found in its native range in North Carolina, Tennessee, Virginia and West Virginia. It is considered locally extinct in Alabama and Georgia. 

  While the species has strongholds in places, green floaters are rare in nearly 80 percent of the watersheds where they naturally occur. More than 75 percent of the nation’s native freshwater mussel species are endangered or threatened, considered to be of special conservation concern, or presumed extinct, according to USWFS.

  The Earth’s sun is seen in this NASA image. Scientists said July might be the hottest month in 100,000 years.  

  The global heat wave of July 2023 has spared Southern Appalachia. So far.

  KNOXVILLE — July 2023 has so far offered a scary look at global climate change around the world, and the month is already one for the record books.

  This month will likely end up being the hottest July on record, globally speaking. That comes after quantitative conclusions from multiple scientists that the past week was, globally, the warmest in 100,000 years.

  The Southern Appalachians have generally been spared from the heat settling on vast portions of the country and world, but that will soon change. The National Weather Service predicts higher than average temperatures flirting with 100 degrees in the Tennessee Valley next week. Record-breaking temperatures are possible. The average high temperature for July in Knoxville is 87 degrees.

  Solar? Gas? Future of Kingston plant up in the air

  KINGSTON — Tennessee Valley Authority is considering whether to go with gas or solar power after it closes the infamous Kingston Fossil Plant in Tennessee.

  The plant has stood since 1955 in Roane County. The federal utility plans to close Kingston Fossil plant and is looking at ways to replace the power it generated. It’s asking the public for comments. The utility’s proposals center around replacing the power generated by the plant with either solar generation or natural gas. One option includes replacing the coal-powered plant at the site with a fossil gas plant.

  TVA recently proposed to retire three units between 2026 and 2031 and the other six units between 2027 and 2033. Ash spilled from a dike at this plant in 2008. A lawsuit was recently resolved surrounding the health damage to people working on cleaning up the spill. TVA has identified trouble with starting up and shutting down the plant for power generation and technical issues with lower boilers as the reasons for closing the plant, not the spill.

  Tennessee Aquarium welcomes 2,500 baby lake sturgeon as restoration effort turns 25 years old

  Casey Phillips is a communications specialist at the Tennessee Aquarium in Chattanooga.

  CHATTANOOGA — The approach of summer coincided with the arrival of thousands of juvenile lake sturgeon in the Tennessee Aquarium Conservation Institute. 

  Biologists at the Aquarium’s freshwater field station welcomed 2,500, 2-inch babies into their care. After a steady diet of bloodworms and brine shrimp, bringing the fish to at least 6 inches, they will be reintroduced into the Tennessee River.

  These tiny fish hold tremendous promise. Adult lake sturgeon may reach lengths of 8 feet and live 150 years. 

  “They start out really small, so it’s shocking to think how big they can get,” says reintroduction biologist Sarah Kate Bailey. “The first year of life is when they grow the quickest. 

  “They grow so fast while we have them here. You’ll go home for the day, come in the next morning, and they look like they’ve grown overnight.”

  Andrew Gunnoe helms spirited efforts to preserve beloved Little River but the current is swift

  MARYVILLE — For 25 years, the handful of men and women involved with the nonprofit Little River Watershed Association (LRWA) have been protecting the crystal clear waters as they plummet from the Great Smoky Mountains before meandering through Blount County and merging with the Tennessee River.
  

  “We see ourselves as the voice of the Little River, speaking for the river and its health,” said Andrew Gunnoe, president of the LRWA Board of Directors.

  From the famous swimming hole at the Wye to the profusion of inner tube rental companies in Townsend, the Little River is one of the region’s most popular spots for water recreation. Further downstream, the waterway becomes an almost perfect spot for fishing, canoeing and kayaking.

  For all the popularity as a recreation stop, the 59-mile stretch of water is also a vital habitat for numerous aquatic species and provides the 120,000-plus residents of Blount County with drinking water.

  Environmental groups sue Tennessee Valley Authority over proposed new power plant

  This story was originally published by Tennessee Lookout.

  NASHVILLE — A trio of environmental groups filed suit against the Tennessee Valley Authority, claiming the utility violated federal law by failing to properly evaluate climate, environmental and financial impacts of a proposed new gas-fired plant in Cumberland City, Tennessee.

  The lawsuit, filed in a Nashville federal court this month, also claims that TVA quietly inked a deal with an international pipeline company to supply the gas-fired plant, even as it publicly went through the motions of seeking input on alternative sources of power to replace the Cumberland Fossil Plant, its aging coal-fire facility located about 60 miles northwest of Nashville.

  The groups are seeking an immediate halt to construction on the gas plant and an order forcing the utility to revise the existing environmental impact study used as the basis for moving forward with the gas-fired plant.

  “Our country’s largest utility has gamed the system to fast-track dirty energy projects and that’s why we’re going to court to stop it,” Gaby Sarri-Tobar, a campaigner with the Center for Biological Diversity, said in a statement. “TVA needs to be held accountable for its reckless pursuit of a new fossil gas plant in the midst of the climate emergency.”

• To critics’ dismay, TVA plans to replace coal with natural gas. The utility also plans to double its solar supply.

  Citizens call on TVA to stop passing gas

  KNOXVILLE — The Tennessee Valley Authority in coming years plans to add both natural gas and solar plants to its portfolio to meet what it says are rising energy demands.

  TVA’s Board of Directors laid out the federal utility’s plan in a meeting at Norris Middle School in May. Environmentalists at a previous hearing criticized the utility’s focus on natural gas rather than renewables or other measures. Other people, largely tied to local power providers, argued that a switch to renewable energy would be unreliable.

  TVA showed a map in a press release following the meeting, showing four proposed natural gas plants and two proposed solar plants. Two of those natural gas plants would be in Tennessee while the other two are planned for Alabama and Kentucky. It stated these new plants will total 3,800 megawatts. It also spoke of its System Operations Center, set to open in fall 2024 in Georgetown to manage the utility’s grid. TVA also stated a desire to research nuclear technologies.

  “Our region is experiencing growth at six times the national average, which means we must invest in our current power system and build new generation so we can continue meeting our region’s demand,” said TVA president and CEO Jeff Lyash.

  Several citizens criticized TVA’s focus on natural gas plants and new pipelines at the listening session May 9. Among them was Clinton resident and activist John Todd Waterman.

• Enviros cheer new Biden plan to limit fossil pollution

  By Thomas Fraser

  WASHINGTON, D.C. — 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.
