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.

CHATTANOOGA — After bulking up all summer on a steady diet of bloodworms and brine shrimp, hundreds of juvenile lake sturgeon finally were returned to their ancestral waters this morning. 

Under a nearly cloudless autumn sky, biologists from the Tennessee Aquarium Conservation Institute and third through fifth grade students from Girls Inc. of Chattanooga’s Fall Break Camp gathered on the north bank of the Tennessee River in Coolidge Park. 

One by one, they carefully made their way to the river’s edge holding clear, water-filled plastic buckets containing five-month-old lake sturgeon. Amidst excited squeals and nervous laughter, they squatted down, gently depositing each sleek, armor-skinned fish into the shallows.

This latest release “class” included 667 lake sturgeon. Comparatively tiny now, these miniature river giants have the potential to reach nine feet in length and could live for up to 150 years. 

Reintroduction events like this are the capstone payoff to a summer spent tirelessly caring for and — most of all — feeding these sturgeon, says Reintroduction Biologist II Teresa Israel. 

“It’s really special. It’s hard to see them go, but it’s a happy day since we’ve seen them get so big, so we know they’ll be successful out there,” she said. “It’s a great accomplishment that completes the circle for all our hard work.” 

Lake Sturgeon are considered endangered in Tennessee. As recently as the 1970s, this species had disappeared from both waterways due to the impacts of damming, poor water quality and over-fishing. Today’s release is the latest in the now-23-year-old effort to bring Lake Sturgeon back to the Tennessee River and Cumberland River.

Editor’s note: The Environmental Management Waste Management Facility (EMWMF) was planned with sufficient capacity to properly accommodate all the problem waste to be generated by the cleanup of the Oak Ridge Reservation. However, to accelerate the cleanup and reduce the cost of preprocessing demolition waste, highly toxic waste was not systematically separated from less contaminated waste that would not have required disposal under Superfund criteria. Thus, EMWMF was approaching its capacity much sooner than projected. Hence, DOE began planning the Environmental Management Disposal Facility (EMDF) on land designated to remain uncontaminated during DOE’s Stakeholder Stewardship process of the late 1990s. 

What did EPA Administrator Regan know when he overruled his experts?

WASHINGTON — A controversial decision by Biden’s Environmental Protection Agency may compromise the protectiveness of radiation cleanups across the country, yet the agency will not release the material explaining the basis for this decision, according to a federal lawsuit filed by Public Employees for Environmental Responsibility (PEER). The suit seeks to find out why EPA allowed a landfill at Oak Ridge, Tennessee, one of the nation’s largest nuclear waste sites, to pollute local waters over the objections of its top legal experts.

The Tennessee Department of Environmental Conservation (TDEC) had objected to plans by the U.S. Department of Energy (DOE) to build a landfill for radiological wastes and debris from demolished structures from the Y-12 National Security Complex and Oak Ridge National Laboratory. TDEC protested that wastewater from the landfill would contaminate Bear Creek, a tributary of the Clinch River. EPA’s acting Regional Administrator agreed with the state.

Electrofishing innovator retires after 30 years of service with TWRA

MORRISTOWN — Bart Carter, Tennessee Wildlife Resource Agency Region 4 Fisheries Program Manager, has retired after three decades of service to the state’s wildlife resources. 

During his 33-year career, his work included improving hatcheries, enhancing fish habitat, restoring streams to native fish fauna, helping discover new species, adding public access areas, and mentoring employees.   

One of his most significant developments during his career was designing and building new backpack electrofishing equipment.

“Electrofishing can be an effective tool for fish community sampling, fish relocation, invasive species eradication, (and) sampling fish tissue contaminants,” said Mark O’Neal, director of ETS Electrofishing systems, LLC in Madison, Wisconsin.

“The tools they use just stun fish and doesn’t kill them. It stuns them out and then they can weigh them and put a tag on them, without having to using a pole with a hook or a net,” O’Neal said.

“It puts out a high DC voltage pulse. On a boat system you have to use a larger pulse. More DC power to drive a current in the water. When the fish experience a DC current they go to the anoid,” O’Neal said.

CHEROKEE — Great Smoky Mountains National Park will host a free youth fishing clinic and an Old Time Music Jam at the Oconaluftee Visitor Center on Saturday, October 21, 2023. Both events are free and open to the public.

In collaboration with the International Game Fish Association, the park will hold the fishing clinic from 10 a.m. to 3 p.m. Try your hand casting a line for local trout and earn your Junior Ranger Angler badge. Learn about fish conservation and ethical angling practices at fun, interactive stations. All fishing equipment will be provided. The first 25 families will receive a free fishing pole to keep! A valid Tennessee or North Carolina fishing license is required for participants 16 or older.
