EPA finally capping toxic waste at South Knoxville Superfund site

KNOXVILLE — The Environmental Protection Agency this week began putting a protective cap on the former Smokey Mountain Smelters site to control its pollution.

The EPA said the cap will protect nearby waterways by stopping stormwater runoff from combining with the toxic waste on site. Engineers and workers began the project the week of July 6.

By cutting it off from the stormwater, the EPA hopes to stop toxins from flowing away either through groundwater or runoff. The site is off Maryville Pike in South Knoxville. Caleb Properties purchased two of the site’s three parcels at the Delinquent Property Tax Sale on May 16. EPA is building the cap and storing the waste in the area Caleb Properties purchased. The agency stated Caleb Properties committed to “allocating a portion of the development of the site for community benefit,” and they’ll still have to work with the EPA’s remedy for cleanup. 

Hellbender Press has reported on the cleanup sites and environmental legacies.

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.

Supreme Court air-pollution ruling calls into stark context all that must be done

This story was originally published by Tennessee Lookout.

KNOXVILLE — The U.S. Supreme Court’s ruling limiting the power of the Environmental Protection Agency to regulate carbon emissions that cause climate change has renewed the spotlight on the Tennessee Valley Authority, the nation’s largest public utility and Tennessee’s primary source of electricity.

The case involved EPA efforts to implement a key provision of the Clean Air Act in a challenge brought by 15 Republican-led states. That provision, which never went into effect, would have required existing power plants to shift from dirty sources of energy — such as coal — to cleaner sources, including solar and wind, as part of an urgent effort to reduce global warming.

Knoxville’s most polluted former industrial site is slated for a massive cleanup soon thanks to funding from the bipartisan infrastructure bill Congress recently passed. The Smokey Mountain Smelters site in Vestal has spent more than a decade on the National Priorities List, commonly called the “Superfund” list, of the most contaminated properties in the U.S. 

The work could start within just a few months, said Rusty Kestle, Environmental Protection Agency project manager for the site. He said it’s the top priority in the Southeast for the infrastructure funding because it’s among the most affordable and ready for action.

The lack of regional and local vehicle traffic during the pandemic greatly reduced measurable pollution in Great Smoky Mountains National Park.

This is your Hellbender weekend read, and the first in an occasional Hellbender Press series about the effects of the Covid-19 pandemic on the natural world

Great Smoky Mountains National Park shut down for six weeks in 2020 during the Covid-19 pandemic. Recorded emissions reductions during that period in part illustrate the role motor vehicles play in the park's vexing air-quality issues. The full cascade of effects from the pollution reductions are still being studied.

Hellbender Press interviewed park air quality specialist Jim Renfro about the marked reduction of carbon dioxide and other pollutants documented during the park closure during the pandemic, and the special scientific opportunities it presents.  He responded to the following questions via email.

Hellbender Press: You cited “several hundred tons" in pollutant reductions during an interview with WBIR of Knoxville (in 2020). What types of air pollutants does this figure include?
