ORNL separates rare earth from the chaff

Membrane solvent extraction process schematicMembrane solvent extraction schematic.   ORNL

OAK RIDGE Caldera Holding, the owner and developer of Missouri’s Pea Ridge iron mine, has entered a nonexclusive research and development licensing agreement with Oak Ridge National Laboratory to apply a membrane solvent extraction technique, or MSX, developed by ORNL researchers to process mined ores. MSX provides a scalable, efficient way to separate rare earth elements, or REEs, from mixed mineral ores.

The MSX technology was pioneered at ORNL by researchers in the Department of Energy’s Critical Materials Innovation Hub, or CMI, led by Ames National Laboratory. The inventors, Ramesh Bhave and Syed Islam of ORNL’s Chemical Sciences Division are named in 26 inventions and five active licenses related to the recovery of REEs.

After years of activism, Atlanta’s South River is now a font of sustainability and fun

This article has been edited since its original publication.

ATLANTA — It has taken decades, but the once-polluted South River is now approved for fishing and recreation, and 40 navigable miles from Panola Shoals, about 30 minutes southeast of downtown Atlanta, to Lake Jackson, are being developed into the South River Water Trail for canoes and kayaks.

“This has always been an environmental justice issue,” said Dr. Jacqueline Echols, board president of the South River Watershed Alliance (SRWA) and driving force behind the cleanup.

The 60-mile South River begins in the 80-percent Black city of East Point, then runs through other predominately Black, South Atlanta communities and into Arabia Mountain Natural Heritage Area, where the Flat Rock Archives “preserves rural African-American history in Georgia.”

WARTBURG — Harvey Broome Group of the Sierra Club and Tennessee Citizens for Wilderness Planning want to encourage the public to weigh in on the proposed Tennessee State Management Plan for Frozen Head State Park & Natural Area in Morgan County.

Some of the proposed developments could drastically impact park natural resources and visitor experiences. Frozen Head hosted nearly 400,000 visitors in 2022. It is frequented by many East Tennessee residents and is an important destination tourist attraction. Importantly, it is an outstanding reservoir of biodiversity in the heart of the Cumberland Mountains.

The Management Plan states Frozen Head State Park and Natural Area mission is “to protect and preserve the unique examples of natural, cultural, and scenic resources and to save one of the last vestiges of undisturbed landscapes in the Cumberland Mountain region,” and park management is intended to “restore and maintain the diversity and integrity of the resource.”

Knox County, TN proposed future land use map

KNOXVILLE — Members of the Knox County Growth Policy Coordinating Committee will hold their second (but first official) public meeting on Monday, Nov. 27 to hear from the public and consider amendments to the Growth Policy Plan that dates back to 2000. The meeting will take place at 5 p.m. in the Main Assembly Room of the City County Building. (This meeting was previously scheduled for Nov. 16.)

The committee’s first of two meetings required by Tennessee State Law to change a growth policy plan had initially been announced for Oct. 24. However, when it became known that the announcement had not been published with due notice in a local newspaper to met the letter of the law, the Oct. 24 gathering was relabeled as a public information meeting only, and its agenda limited to merely provide an introductory presentation about the Advance Knox process and its proposals, with an opportunity for brief citizen statements.

Climate change mitigation activities at state and city levelsThe Tennessee Valley states (TN, AL, MS) are among the most irresponsible in their languid pondering about climate change mitigation.  Illustration from the 5th National Climate Assessment

Urgent investments in local solutions are needed now more than ever as climate impacts grow across the South

The 5th National Climate Assessment, released this week by the U.S. Government, reports on the current climate trends, impacts and solutions across the country. It underscores the urgency and opportunities for meaningful climate action.

This year, it includes a chapter highlighting how climate is impacting our Southeastern landscape and communities, plus what trends we can expect in the years ahead. 

The report substantiates what we’ve been witnessing on the ground: Extreme heatwaves are already more common, sea level rise is encroaching into coastal communities and throughout the region, we’re seeing more flooding from increasingly unpredictable, volatile storms. According to the report, the country now sees a billion-dollar weather disaster every three weeks on average. In the 1980s, that average was every four months.

Enviva’s financial problems shed light on biomass energy flaws

npr.brightspotcdn.webpThe Impacted Communities Against Wood Pellet Coalition (ICAWP) organized the protest and says the company has been ignoring the concerns of impacted communities while receiving millions of dollars in subsidies and tax breaks from the state.  ICAWP

This week Enviva, which is the world’s largest wood pellet manufacturer, saw its stock price fall by more than 90 percent from its height earlier this year following a grim financial report from the company. The company’s money problems show the massive flaws with the biomass energy industry and are due in part to the company being held accountable for its polluting pellet plants.  

Enviva operates pellet plants across the South. These dirty facilities release huge amounts of air pollution, dust and fine particulates that can cause asthma and respiratory illnesses in nearby communities. The hazardous plants are often times sited near communities of color that are already overburdened with industrial pollution. 

Enviva’s current financial crisis is due in part to the company being forced to internalize the environmental costs of its dirty operations, rather than pushing them off onto nearby communities. SELC, along with community partners across the region, have scored major victories against Enviva and other pellet companies, forcing them to install pollution controls and better protect people living nearby.  

“Enviva’s wood pellet plants have caused long-lasting damage to communities across the South. The company’s financial problems are partially caused by communities standing up and pushing back on this dirty industry,” said Heather Hillaker, Senior Attorney for SELC.

Intergenerational Playspace open in North Knox

Playground

Legacy Parks Foundation cut the ribbon on the Intergenerational Playspace at Beverly Park in North Knox County. It is the first park in the region to be purposefully designed to create active interactions between multiple generations, especially children and seniors.

“This park was made possible by our many partners that supported and funded the project,” said Carol Evans, Legacy Parks’ executive director.

Legacy Parks was awarded a $150,000 two-phase grant from the Trinity Health Foundation to research, design and create the Playspace. Additional grants and construction services provided by Knox County made the park possible

Construction continues on Lakeview Drive in GSMNP

Extreme drought endangers fish species

Drought conditions threaten some of the nation’s most-endangered fish species

Casey Phillips is a communications specialist at the Tennessee Aquarium in Chattanooga.

CHATTANOOGA — The endless parade of sunny, cloudless days in Chattanooga for the last two months may seem like the stuff of dreams to anyone planning an outdoor activity. However, this fall has turned into a blue-sky nightmare for aquatic species living in smaller creeks and streams.

“Some of those headwater pools are going to dry up, and we’ll lose large numbers of populations,” said Dr. Bernie Kuhajda, an aquatic conservation biologist at the Tennessee Aquarium Conservation Institute. “It just doesn’t look good for our headwater fish communities out there. They’re really getting stressed.”

Less than half an inch (0.42 inches) of rain fell in Chattanooga during a 72-day span between Aug. 30 and Nov. 9, according to meteorological data recorded at Lovell Field. That’s just 0.16 inches more than fell in Death Valley, California, during the same period, according to the National Oceanic and Atmospheric Administration (NOAA).

As of the latest weekly report by the government’s U.S. Drought Monitor, most of Hamilton County is now considered to be experiencing a D4 or “exceptional” drought, the Monitor’s most severe drought category.

Bad news for endangered fish species like the Barrens Topminnow and Laurel Dace.

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).

Ela Dam Removal Coalition moving forward after $4 million grant from U.S. Fish and Wildlife to commence river restoration project 

Erin McCombs is the Southeast Conservation Director of American Rivers.

CHEROKEEAmerican Rivers is working with a team on a massive effort to remove the Ela dam and restore the land and Oconaluftee River to its natural condition. Partnering with the Eastern Band of Cherokee Indians (EBCI), American Rivers is part of a coalition of federal, state, public, private, and non-profit organizations that has formed to remove the Ela dam.

Truly a village effort, the Ela Dam Coalition includes the EBCI, American Rivers, Mainspring Conservation Trust, the North Carolina Wildlife Resources Commission, the U.S. Fish and Wildlife Service, the Southern Environmental Law Center, the Environmental Protection Agency, American Whitewater, Swain County, the Army Corps of Engineers, and Northbrook Carolina Hydro II.

“Healthy rivers are essential to all life, and removing a dam is the fastest way to restore a river’s health. We appreciate this initial investment by U.S. Fish and Wildlife Service in  the restoration of the Oconaluftee River. We look forward to working with them to leverage this investment to fully realize this project to revitalize fish and wildlife habitat and restore vital cultural connections. We are grateful to the Eastern Band of Cherokee Indians for their leadership, and for the partnership of Mainspring Conservation Trust,” said Tom Kiernan, American Rivers President and CEO.  

Blocking the Oconaluftee River’s natural flow impacts the aquatic habitats of many native fish, mussels, birds, and other wildlife which require it for sheltering, feeding, reproducing, and thriving in their natural environment. The removal of Ela dam will result in a cultural reconnection of the Oconaluftee River to the Cherokee people and the Qualla Boundary. 

The Oconaluftee River is home to 11 sensitive and rare aquatic species, some of which are only found in a few streams and rivers in western North Carolina, including the federally endangered Appalachian elktoe freshwater mussel, the Sicklefin Redhorse (NC Threatened), and Eastern Hellbender (NC Special Concern). Once complete, 549 miles of the Oconaluftee River watershed will be restored and expand habitat for these species.
