  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.

• 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.

  Potential water runoff issues stall future Oak Ridge landfill construction

  OAK RIDGE — A landfill intended to hold potentially toxic debris from the demolition of legacy Oak Ridge research facilities is moving forward but construction won’t start until it is definitively determined whether the site could pollute ground and surface water.

  As reported previously by Hellbenderpress, environmentalists fear toxins leaking out of the proposed landfill could contaminate waterways and make their way into fish that people might catch downstream. The landfill’s contractor, however, said leaving buildings full of toxic residue standing may be more dangerous for workers and nearby residents and the landfill will help get the buildings quickly demolished. The contractor is doing a mock-up study this year to see how best to handle water issues on the future landfill site.

  This summer, the contractor United Cleanup Oak Ridge LLC will choose a subcontractor and do field work. Ben Williams, the Department of Energy’s public affairs specialist, said roads and utilities will need to move to get the site ready at that time. But UCOR stated it won’t build the landfill until after a water study spanning “two wet seasons,” beginning later this year. 

• Water and waste on TVA agenda as utility plans Bull Run shutdown

  Bull Run Fossil Plant in Claxton, Tennessee, was originally commissioned 55 years ago but TVA is now soliciting public input on the best way to shut down operations. Tennessee Valley Authority

  TVA solicits public input following release of environmental assessment for Bull Run Fossil Plant decommission

  CLAXTON — Tennessee Valley Authority plans to close its Bull Run Fossil Plant (BRF) in Anderson County, but it’s still looking for public input on what comes next.

  “As a large, inflexible coal unit with medium operating costs and a high forced outage rate, BRF does not fit current and likely future portfolio needs,” the federal utility said in a draft Environmental Assessment.

  TVA is looking at three different options for the future of the structures still standing on the site by the Clinch River near Oak Ridge: taking down all structures; taking down some of them; or leaving everything standing. A recent report lays out the environmental consequences of each of these actions. The report, in draft form, is against that third choice, listing it as only an option for the sake of comparison.

  “If the facility is left in the “as-is” condition, it likely would present a higher risk than Alternatives A or B for the potential to contaminate soil and groundwater as systems and structures degrade. As such, this alternative is not a reasonable alternative,” the draft states.

  TVA stated its considering removing “all or most of the buildings and structures” on a 250-acre area. After closing the plant, but before any demolitions, TVA will begin by removing components that may be used at other TVA sites, draining of oil and fluids from equipment, taking ash out of the boilers, removing information technology assets, removing plant records and other tasks.

  The Bull Run Environmental Assessment is 170 pages long and available for public review. It doesn’t directly tackle the coal ash storage conundrum that has grabbed the attention of politicians, nearby residents and environmental activists, because that issue involves separate regulations. 

• Every TVA coal-fired plant in Tennessee is leaking dangerous contaminants at unsafe levels, report concludes

Tennessee Valley Authority

  Report: TVA’s Allen Fossil Plant in Memphis ranks No. 10 in most contaminated U.S. sites

  This story was originally published by Tennessee Lookout.

  The Tennessee Valley Authority’s coal ash dumps in Memphis rank among the worst in the nation for contamination of groundwater with cancer-causing toxins, according to a new report that relied on the power provider’s own records.

  TVA’s coal ash dumps at the now-defunct Allen Fossil Plant rank as the 10^th worst contaminated sites in the country in a report released earlier this month that examined groundwater monitoring data from coal-fired plant operators, including TVA.

  TVA’s own monitoring data shows its Memphis dumps are leaking arsenic at levels nearly 300 times safe drinking water limits. Unsafe levels of boron, lead and molybdenum are also being recorded there.

  The report, prepared and published by the Environmental Integrity Project (EIP) and Earthjustice, shows that coal ash dumps at every TVA coal-fired facility across Tennessee are leaking dangerous contaminants at unsafe levels, including arsenic, cobalt, lithium, molybedenum, boron, lead and sulfate, into groundwater.

  NASHVILLE — In the wake of major coal ash spills from power plant containment ponds in Tennessee and into the Dan River along the North Carolina and Virginia border, the federal Environmental Protection Agency in 2015 laid out the first federal rules for managing the ash, one of the nation’s largest waste streams, and the toxins it contains.  

  But more than seven years later, few utilities and other owners responsible for the often unlined pits where billions of tons of ash leach heavy metals and other toxins into groundwater are planning comprehensive cleanups, per a report released this month by a pair of environmental groups.

  SELC, others file suit in hopes of dissuading TVA from future fossil options

  This story was originally published by Tennessee Lookout.

  CLARKSVILLE — On behalf of the Tennessee Chapter of the Sierra Club and Appalachian Voices, the Southern Environmental Law Center asked TVA to prepare a supplemental environmental statement to address concerns with TVA’s draft environmental impact statement, which details the agency’s plans to retire the Cumberland Fossil Plant.

  The Cumberland Fossil Plant, about 22 miles southwest of Clarksville, is TVA’s largest coal-fired power station and was built between 1968 and 1973. TVA plans to retire each unit of the two-unit, coal-fired steam-generation plant separately: one unit no later than 2030, and the second unit no later than 2033. But the plant will need to be replaced, and TVA is currently considering three alternatives to fossil fuel, including natural gas and solar energy, according to its draft EIS.

  (Tennessee Valley Authority already plans to close down the Knoxville-area Bull Run fossil plant in Claxton next year).

  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.

  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.”
