Waste at Smokey Mountain Smelters finally sealed

EPA’s Peter Johnson addressed the cleanup efforts and some general ideas of what will come next in a recent YouTube video uploaded Monday, Oct. 23.
 

EPA consolidated toxic South Knoxville smelter refuse in single on-site landfill.

KNOXVILLE — The Smokey Mountain Smelters site is in the Vestal Community at 1508 Maryville Pike near Montgomery Village Apartments.

“We are excited to announce the cleanup at Smokey Mountain Smelters has been completed,” EPA remedial project manager Peter Johnson said.

From the 1920s through the 1960s, agricultural and chemical companies operated at the site before Smokey Mountain Smelters, also known as Rotary Furnace Inc., came to the location in 1979. The company melted scrap aluminum and aluminum dross together to cast the byproduct into aluminum bars. These operations continued until 1994.

Johnson has said in other talks the dross and saltcakes left over from the process react with water, releasing heat and ammonia gas. They leach aluminum, ammonia, chloride “and many other contaminants,” he said. Smokey Mountain Smelting’s toxins have flowed through groundwater into a tributary of Flenniken Branch, causing concerns about effects on fishing.

In 2010 the EPA placed the site on the Superfund program’s National Priorities List (NPL) because of contaminated soils, sediment and surface water resulting from past industrial operations at the site. The EPA did some cleanup work in 2010 and 2011.

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.

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.
