TDEC releases money to help rubber meet the road

KNOXVILLE — The Tennessee Department of Environment and Conservation granted $350,197 to the University of Tennessee from the Tire Environmental Act Program

UTK will provide matching funds of $512,793 and use the grant toward a research and development project that will develop multiple sustainable technologies for the application of tire rubber in road construction. The project costs $862,990 and has the potential to create a vast market for waste tires unrivaled in size by any other use of scrap rubber.

 

“We are seeing great advances in repurposing tires for environmental benefits,” said TDEC Deputy Commissioner Greg Young. ”Programs like this not only help clean up sites of used tires, they involve innovative new uses for them. We congratulate UT-Knoxville on this project.”

UTK is partnering with the Tennessee Department of Transportation (TDOT) to install a series of pavement test sections using the technologies developed from this project. Benefits of including rubber in asphalt pavement mixes include improved skid resistance, cracking resistance, and noise reduction.

The purpose of the Tire Environmental Act Program is to select and fund projects that best result in beneficial uses for waste tires. Projects must qualify for one of three categories: tire processing/recycling, tire-derived material use, or research and development. The program provides grant funding to eligible entities, including local governments, non-profit organizations, higher education institutions, K-12 schools and for-profit businesses.

Tennessee established the Tire Environmental Fund in 2015. Upon the first retail sale of a new motor vehicle to be titled and registered in Tennessee, a flat fee based on the number of a vehicle’s wheels is assessed. The fee goes into the fund, which is used for projects creating or supporting beneficial end uses for waste tires.

Since 2015, grantees have been awarded almost $6.8 million, and approximately 5.5 million tires or nearly 58,000 tons of scrap tires have been diverted from landfills. The tires are repurposed for use in rubberized asphalt, tire-derived aggregate, tire-derived fuel, granulated rubber porous flexible pavement, and other beneficial end uses that result in tires being diverted from landfills for a higher and better use.

Tennessee developing a plan to reduce polution

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).

CLAXTON — An East Tennessee site that has been contaminated for about 50 years with radioactive waste is set to be cleaned up with about $13.5 million in funding from the Environmental Protection Agency, the Tennessee Department of Environment and Conservation told Anderson County on October 9. 

The American Nuclear Corporation site, located in Claxton, Tennessee, has been a source of concern for Anderson County Government for years. Local officials have reached out at various points since at least 2008 to the state, the EPA and their district’s congressmen for help on cleaning up the site, according to a compilation of county records distributed last year by then County Commissioner Catherine Denenberg to the county’s intergovernmental committee.  

“I don’t know if we’re on camera, but in case we are, I am not going to dance but I am so darn excited about this!” County Mayor Terry Frank said after the announcement at the county’s intergovernmental meeting. “This is huge for Anderson County.”

In the 1960s, the American Nuclear Corporation “manufactured radiological sources for medical institutions,” a 2010 county application for the EPA’s National Brownfield Program grant said. The company had obtained source materials for their products from the Department of Energy. Isotopes that were handled included Cobalt-60 and Cesium-137, the application said. 

“Poor housekeeping was a problem during the entire period that the plant was in operation, and is extensively documented in compliance letters by the Tennessee Department of Public Health — Division of Occupational and Radiological Health. ANC was repeatedly cited for violations involving radioactive material,” the application said.

Lawsuit probes Oak Ridge Clean Water Waiver

EMDFlocationEditor’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.

Duck RiverMarshall CoThis 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

This story was originally published by Tennessee Lookout

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.

The need for Marshall County,  to have its own water supply, which it has never had, is becoming more urgent with an influx of new residents. But environmental activists say the nearby Duck River, which is biologically diverse, may not be the best option.
