Long time residents and conservation groups say industry lured by the state, population growth are draining water from a river prized for its biodiversity

COLUMBIA ­­— When Gov. Bill Lee announced the state had lured a General Motors lithium battery supplier to Spring Hill three years ago, it was his largest economic announcement to date:

A $2.6 billion corporate investment; 1,300 new jobs; a major stepstone along Tennessee’s path to become an EV hub — helped along by a then-record $46,000 per job in taxpayer incentives.

The factory deal’s less conspicuous specs — its continuous need for 1.4 million gallons of water per day — is now figuring in a larger battle pitting citizens and conservation groups against state environmental regulators.

Last month, the Tennessee Department of Environment and Conservation (TDEC) granted permission to Columbia Power and Water Systems — which pumps water to the new Ultium Cells plant — to increase its current withdrawals from the Duck River by 60 percent.

It’s one of eight water companies along the Duck River seeking to dramatically increase water draws to meet rising demands for water in the rapidly growing five-county region southwest of Nashville.

COLUMBIA — The Duck River, which winds through seven Middle Tennessee counties for more than 260 miles before reaching the Tennessee River, is among the most endangered rivers in the United States, according to a new report by the advocacy group American Rivers.

Threatened by population growth, development and climate change “urgent action is needed to safeguard this vital ecosystem,” the report released Tuesday said.

The Duck River serves as the source of drinking water for nearly 250,000 Tennesseans. Industry and agriculture depend on it, too. Often considered one of Tennessee’s most pristine waterways, it draws more than 150,000 people each year for boating, fishing and other recreation. Last year, in an effort to protect the river from a controversial plan to establish a landfill near its banks, state lawmakers designated a portion of the river in Maury County an official state scenic waterway.

Tennessee wants to prioritize a developing plan to reduce pollution causing climate warming and wants to hear from residents. A survey was created for residents to share what they wanted to see in a statewide climate pollution reduction plan. The survey closed on Nov. 15.

This planning process is being led by the Tennessee Department of Environment and Conservation (TDEC) and is part of the Tennessee Volunteer Emission Reduction Strategy (TVERS), an emission reduction plan currently being developed by TDEC with support from various partners. This plan is funded through the U.S. Environmental Protection Agency’s (EPA) Climate Pollution Reduction Grant (CPRG) program, which was established in the Inflation Reduction Act of 2022 (IRA).

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.

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.

The TN Lunabotics, science and sustainability get together at BOSS event

Updated March 2023 with notes from a reader:

My name is Allison, and I am a teaching volunteer with Students For Research. I am reaching out because our class found your website very useful while researching STEM resources that can help students discover the various aspects of science, technology, engineering and math. Many of our current students are interested in learning more about how topics associated with STEM work, especially in relation to online research, either for school or for their future careers. Your website ended up being featured by our students, so we wanted to notify you and say thank you!

As a part of the assignment, one of our students, Becky, did some research on her own time and found this informative page for more STEM using this resource. The team found it helpful as it provided guidance on how libraries can introduce children to STEM and continue to provide resources as they progress through their education. 

I was hoping you would be able to include this resource on your website, even if it's only for a short time. I think your other visitors might find it helpful, and it also helps our group of students cite appropriate resources and stay engaged whenever outreach yields positive feedback everyone can see. Please let me know if you would be willing to add it so I can share the exciting news with Sophie and the rest of her fellow students. I appreciate your help!

KNOXVILLE — What do environmental, social and economic sustainability have in common?

There are numerous ways to answer that question, but for those who pay close attention to education or economics it’s an accepted fact that the future belongs to societies that invest heavily in STEM (Science, Technology, Engineering and Mathematics). 

That’s why educators at all levels are pushing students towards those subjects at every opportunity, as was evidenced Jan. 21 at Big Orange STEM Saturday (BOSS) at the University of Tennessee.

About 150 high school students picked from communities across East Tennessee spent much of their Saturday at John C. Hodges Library, getting a first-hand taste of what awaits them should they choose to pursue careers in STEM through the UT system.

A crimper is attached to the back of a tractor on a farm in the Sequatchie River Valley. A relatively recent agricultural technique, crimping has been shown to reduce farmers’ input costs and improve soil quality. Recently, USDA approved funneling $10 million into a six-county region of Southeast Tennessee. This money will fuel conservation-minded improvements for landowners, including lowering the cost to rent equipment like crimpers and subsidize the planting of cover crops to improve soil health and reduce sedimentation in nearby streams.  Tennessee Aquarium

Targeted collaborative conservation will help local agricultural operations improve soil and water quality and protect aquatic life

CHATTANOOGA — Tennessee is as much a patchwork quilt of farms as it is an intricately woven lacework of streams and rivers. Soon, farmers and the aquatic life living alongside them will reap the benefits of $10 million in federal funds to support water-friendly agricultural improvements in the rolling uplands of the state’s southeastern corner.

The U.S. Department of Agriculture (USDA) approved the allocation of more than $197 million to support Regional Conservation Partnership Programs (RCPP) throughout the nation. These initiatives promote coordination between USDA’s Natural Resources Conservation Service (NRCS) and partnering organizations that are already engaged in conservation efforts.

This biologically rich stretch of the Duck River could soon be the site of a large municipal water intake facility.

Duck River targeted by thirsty, growing municipalities in Nashville area

Marshall County, located outside what was once considered the boundary edge of growing suburbs circling Nashville, has seen explosive growth of its own in recent years — call it the Williamson County overflow effect, says County Mayor Mike Keny.

Drawn by more affordable housing, jobs and the rural character of the county — about an hour from Nashville in the “heart of the Southern Automotive Corridor” (as local economic development officials call it) — the influx of residents, and some relocating business and industry, has brought new urgency to a long-standing reality.

The county doesn’t have its own water supply. For decades, it has had to pay wholesale for drinking water from the cities of Murfreesboro and Lewisburg. That supply is no longer adequate.

A new proposal by county officials calls for building a water treatment facility along the banks of the Duck River in northern Marshall County capable of siphoning up to 6 million gallons of water per day; establish a reliable local water supply for decades to come.
