 Bull Run Fossil PlantThe regionally famous Bull Run smokestack was demolished this summer by the Tennessee Valley Authority as the federal utility phases out the use of coal to generate electricity. Climate activists are alarmed by TVA’s plans to replace coal with natural gas, itself a powerful greenhouse gas pollutant.  Tennessee Valley Authority

What’s next for mammoth utility after demolition of Claxton, Tenn. landmark stack?

CLAXTON — In a matter of seconds, the old smokestack fell like a giant tree, heaving clouds of dust as it hit the ground. Workers set off the implosion with a loud boom at the base of the towering smokestack on June 28, at Bull Run Fossil Plant just outside of Oak Ridge. Minutes earlier, the shorter and more modern ‘scrubber’ bit the dust in similar fashion.

Georgia and North Carolina lead EV investment and jobs; Florida tops market share and growth; Tennessee and Alabama lag behind

Stan Cross leads the Southern Alliance for Clean Energy dynamic Electric Transportation Team. 

KNOXVILLE — Misinformation about the technology and the state of the electric-vehicle market is rampant. But beyond the noise are the facts, which show that the Southeast’s EV market is zipping along.

The Southeast continues to lead the nation in electric vehicles and battery-related jobs and private-sector investments. As of the end of 2024, updated data from the fifth annual Transportation Electrification in the Southeast report found that the region is home to a whopping 38 percent of the nation’s $215 billion in announced private-sector EV and battery investments and 31 percent of the anticipated 238,000 jobs. Georgia remains No. 1 in anticipated jobs and committed investments, with North Carolina a close second.  

These investments deliver economic development and employment to our region’s rural communities. Toyota’s $13.9 billion battery manufacturing facility in Randolph County, North Carolina, is at the top of the rural economic development list. The facility is expected to create 5,100 jobs and is the nation’s most valuable clean energy investment. Hyundai has made the second-largest regional investment at its battery manufacturing and EV assembly plant in Bryan County, Georgia. That investment tops $6 billion and is expected to create 3,400 jobs. It has had a massive ripple effect, with Hyundai suppliers announcing more than $2.7 billion in investments and an anticipated 6,900 jobs across the state.

TrichloroethyleneTrichloroethylene is among the chemicals deemed a serious public health risk by way of the Environmental Protection Agency’s IRIS database. Legislation in Congress could bar the use of IRIS and its associated scientific methods from being used to calculate the environmental and human health risks of chemicals such as TCE, a proven carcinogen.  ChemLibrarian/Wikipedia Commons

Two bills in Congress would prohibit the Environmental Protection Agency from using hundreds of chemical assessments completed by its IRIS program in environmental regulations or enforcement.

This story was originally published by ProPublica.

WASHINGTON, D.C. — For decades, Republican lawmakers and industry lobbyists have tried to chip away at the small program in the Environmental Protection Agency that measures the threat of toxic chemicals.

Most people don’t know IRIS, as the program is called, but it is the scientific engine of the agency that protects human health and the environment. Its scientists assess the toxicity of chemicals, estimating the amount of each that triggers cancer and other health effects. And these values serve as the independent, nonpartisan basis for the rules, regulations and permits that limit our exposure to toxic chemicals.

Now IRIS faces the gravest threat to its existence since it was created under President Ronald Reagan four decades ago.

Legislation introduced in Congress would prohibit the EPA from using any of IRIS’ hundreds of chemical assessments in environmental rules, regulations, enforcement actions and permits that limit the amount of pollution allowed into air and water. The EPA would also be forbidden from using them to map the health risks from toxic chemicals. The bills, filed in both the U.S. Senate and House of Representatives earlier this year, are championed by companies that make and use chemicals, along with industry groups that have long opposed environmental rules. If it becomes law, the “No IRIS Act,” as it’s called, would essentially bar the agency from carrying out its mission, experts told ProPublica.

“They’re trying to undermine the foundations for doing any kind of regulation,” said William Boyd, a professor at UCLA School of Law who specializes in environmental law. Boyd noted that IRIS reports on chemicals’ toxicity are the first step in the long process of creating legal protections from toxic pollutants in air and water.

“If you get rid of step one, you’re totally in the dark,” he said.

If the act passes, companies could even use the law to fight the enforcement of environmental rules that have long been on the books or permits that limit their toxic emissions, environmental lawyers said.

Groups to carry on air quality work, defend U.S. investments and ensure voices are heard from all communities

This story is from North Carolina News Service.

RALEIGH — President-elect Donald J. Trump retakes office in less than a week amid promises to roll back efforts to combat climate change. A friendly Congress could follow suit. But state-level efforts to address the crisis will continue in North Carolina, at least.

Trump has promised to repeal the Inflation Reduction Act passed under President Joe Biden, which earmarked billions for climate-resilience and alternative energy projects. Brittany Griffin with the nonprofit CleanAIRE NC says tinkering with the law would hurt the state, including its ability to prepare for more severe weather as climate change worsens. But she says there are still glimmers of hope on the state level.

“We still have a lot of state-led policies, and then our makeup now of the General Assembly looks different. We have a governor who also is pretty well-informed and, I believe, dedicated to addressing environmental issues in our state,” he said.

Griffin added that her organization will be working with community and legal partners to resist potentially harmful changes under the Trump administration, and ensuring that all citizens have a voice in their environment. CleanAIRE NC’s community science manager Daisha Walls is on the Environmental Justice Advisory Council for the Governor’s Office.

Griffin noted that there are a number of ways CleanAIRE NC is helping people feel more empowered, such as through its air monitoring networks in communities across the state and clean energy transportation efforts in rural areas, and said community member involvement is important to the state’s response to climate change.

“When they amplify their voice, it allows them to feel like they are participating in the process of shaping environmental policies as it relates to their communities,” she said.

North Carolina lawmakers have passed climate goals under the state’s Carbon Plan that aim to reduce Duke Energy’s carbon emissions by 70 percent by 2030 and reach carbon neutrality by 2050. But Griffin said the current plan falls short for the state’s underserved and impacted communities. However, it is renewed every two years and she hopes they have a larger say in the next iteration.

“We at CleanAIRE NC would like to make sure there’s more inclusion for all communities in the planning process so they can actually more directly benefit from it,” she said.

Information will help timber gleaning, fire-hazard mitigation

Stephanie Seay is a senior science writer and communications specialist at Oak Ridge National Laboratory.

OAK RIDGE — A visualization tool that tracks changes to the nation’s forests in near-real time is helping resource managers pinpoint areas with the most damage from Hurricane Helene in the Southeast.

The ForWarn visualization tool was co-developed by Oak Ridge National Laboratory with the U.S. Forest Service. The tool captures and analyzes satellite imagery to track impacts such as storms, wildfire and pests on forests across the nation. 

When staff with the Forest Service’s Eastern Forest Environmental Threat Assessment Center in Asheville, North Carolina, were unable to work in the immediate aftermath of Helene due to utility outages, the ORNL-hosted ForWarn system continued monitoring the storm’s impact and providing reports. ForWarn indicated areas of severe disturbance to the forest canopy that were later confirmed by aerial photography. 

“ForWarn helps quickly identify areas that may need remediation such as timber harvesting or prescribed burns as piles of felled trees dry out and potentially pose wildfire hazards,” said ORNL’s Jitendra Kumar.

GATLINBURG — Great Smoky Mountains National Park staff continue to assess the damage sustained by the country’s most-visited national park during Tropical Storm Helene. (The storm was at tropical storm strength when it struck the mountains Sept. 26-27, prompting a rare tropical-storm warning for Western North Carolina).

The Cataloochee and Big Creek areas on the North Carolina side in Haywood County were particularly hard-hit, and significant damage was reported to park cultural resources and road and bridge infrastructure. Those areas remain closed. Most roads and trails on the Tennessee side of the national park are open. Cataloochee is a valuable tourist draw during the fall rutting season of elk populations successfully reintroduced to the park in the 1990s.

Here’s an update from the National Park Service:

“The park experienced substantial damage, particularly in North Carolina, including Balsam Mountain, Big Creek and Cataloochee Valley.

“Within the park, the Cataloochee Valley saw the most significant impacts from Hurricane Helene and will be closed until further notice as staff address damage. Flooding from Rough Fork Creek washed out several roads in the valley. Upper Cataloochee Valley Road saw the worst damage and is not drivable. Various levels of erosion and flooding impacted all trails in Cataloochee Valley and nearly all footlog bridges in the area were washed away during the storm. Cataloochee Valley also experienced fallen trees, flooding at campsites and damaged power lines. There were impacts to historic buildings, particularly the Caldwell Barn, which park staff are currently working to stabilize.
“The Balsam Mountain and Big Creek areas are also currently closed until further notice because of storm damage and safety concerns.

“Most trails on the Tennessee side of the park are open; several trails on the North Carolina side are closed. The park continues to assess the trails on the eastern end of the park to find the western edge of the damage in the backcountry. Examples of trails that were severely impacted include Big Creek Trail, which saw damage throughout its length and lost a 70-foot steel bridge and its abutments. Gunter Fork Trail experienced a landslide that took out 100 feet of trail.
“While there has been some significant damage in the eastern area of the park, many miles of trails in western sections of the park have low impacts and few downed trees. Visitors planning to hike in the Smokies are encouraged (as always) to check the park website and/or talk to staff in visitor centers or the backcountry office about current trail conditions.”

Fourth chemical fire at pool-chemical plant since 2004 prompts widespread evacuations

ATLANTA — The eastern side of the Atlanta metropolitan area was blanketed the morning of Sept. 30 with a fog of smoke and chlorine-scented gases, surprising residents already rattled by Hurricane Helene and an unrelated failure at the Adamsville Pumping Station

The heavy, blue-green mist was coming from BioLab, a pool chemical manufacturing facility in Rockdale County, 23 miles southeast of downtown.

City officials were taken by surprise. This was at least the fourth time BioLab had caught fire since 2004, but prevailing winds usually carry the toxic plume across rural counties and into the Georgia mountains. Hurricane Helene had scrambled wind patterns, however, and pushed it into wealthy, suburban DeKalb and Gwinnet counties and parts of Fulton County.

Rockdale County had begun evacuating 19,000 Conyers residents early Sunday morning, when the fire began. Another 90,000 residents were told to shelter in place, with windows sealed shut and ventilation systems turned off.

The fire itself was extinguished by late afternoon, but the sprinkler system had soaked mountains of reactive pool and spa chemicals with water. The resulting plumes of chlorine, particulates and other chemicals spread across Rockdale, prompting the county to close schools and businesses for the following day.

ERWIN — The death toll from Hurricane Helene climbed to at least 180 people on Wednesday, making it the deadliest hurricane to hit the United States in 50 years with the exception of Hurricane Katrina, which claimed over 1,800 lives in 2005 in what was also a largely impoverished area.

In one-hard hit community in the mountains of northeast Tennessee, emotions grew high as Spanish-speaking family of missing loved ones accused first responders through an interpreter of showboating, classism and preferential rescues during a tense press conference broadcast live on X.

The mounting death toll and increasingly fruitless searches came as millions of people spent their sixth day without running water or power and an ad hoc army of first responders, volunteers and National Guard troops struggled to deliver life-saving supplies to communities throughout the Southern Appalachians that were cut off by the record breaking flash floods spawned by the storm.

In Erwin, a town of 6,000 in Unicoi County, officials confirmed that a criminal investigation had been launched into the conduct of a manufacturing company that was accused of forcing employees to keep working even as floodwaters rose to dangerous levels.

Join the Rally for the Valley 2.0

TVA protest

NASHVILLE — Join the rescheduled Rally for the Valley on Sept. 21 2024 at Centennial Park for a day filled with fun, music, learning and community spirit.

The rally, organized by the Clean Up TVA Coalition, which includes Southern Alliance for Clean Energy and other allies, calls on the Tennessee Valley Authority (TVA) to stop its gas buildout and lead the way to a fossil-free future.

The decisions in front of TVA are significant. They will impact the health and safety of our communities, how much we pay to keep the lights on, and whether we meet our climate targets and achieve energy justice. We are mobilizing with communities from across Tennessee to urge TVA leaders to change course before its too late.

What might Tennessee’s energy-efficiency rebate plan look like, and when?

This article was originally published by Tennessee Lookout.

NASHVILLE — More than $8 billion flagged for home energy rebates in the Inflation Reduction Act is beginning to trickle out of federal coffers, but Tennessee residents will likely have to wait until the spring of 2025 to start applying for their chunk of change.

Each state must shape its own plan to dole out the funding, which can put money residents spend on energy efficiency upgrades back into the households’ pockets if they meet certain requirements. New York and Wisconsin became the first states to begin offering federally funded home energy rebates to their residents in mid-August, two years after President Joe Biden signed the Inflation Reduction Act and its many energy-focused subsidies into law.

In total, the rebate funds are expected to impact between 1 to 2 percent of households across the nation.

Tennessee submitted its application to the U.S. Department of Energy (DOE) for the more than $167 million earmarked for the state in mid-August. Tennessee’s 2025 rollout timeline largely depends on how quickly the DOE approves the state’s applications and when Tennessee can execute a contract with the Tennessee Valley Authority — its chosen implementer — to put the program into action.

debby goes 20240805Hurricane Debby made landfall near the town of Steinhatchee, Florida, at 7 a.m. Aug. 5, 2024, as a Category 1 storm. As it moved northeast, the storm stalled over the U.S. Southeast and delivered torrential rainfall. Some areas of South Carolina and Georgia recorded more than 20 inches of rain as the storm crawled northeast toward a second landfall (this time as a strong tropical storm) near Myrtle Beach, S.C.  NOAA

A warming climate means more water vapor, which means bigger and wetter tropical storms

(This story was originally published by The Conversation.)

Tropical Storm Debby was moving so slowly, Olympians could have outrun it as it moved across the Southeast in early August 2024. That gave its rainfall time to deluge cities and farms over large parts of Florida, Georgia and the Carolinas. More than a foot of rain had fallen in some areas by early Aug. 7, with more days of rain forecast there and into the Northeast.

Mathew Barlow, a climate scientist at UMass Lowell, explains how storms like Debby pick up so much moisture, what can cause them to slow or stall and what climate change has to do with it.

What causes hurricanes to stall?

Hurricanes are steered by the weather systems they interact with, including other storms moving across the U.S. and the Bermuda High over the Atlantic Ocean.

A hurricane may be moving slowly because there are no weather systems close enough to pull the hurricane along, or there might be a high-pressure system to the north of the hurricane that blocks its forward movement. In this case, a high-pressure system over the western U.S. was slowing Debby’s forward progress and the Bermuda High — which is a large, clockwise circulation of winds that generally runs up the East Coast — wasn’t close enough to be a factor.

That’s similar to what happened with the remnants of Hurricane Harvey in 2017, one of the best-known examples of a stalled hurricane. High pressure over the U.S. blocked its forward movement, allowing it to drop more than 50 inches of rain on parts of Texas.

Slower-moving storms have longer to rain over the same area, and that can dramatically increase the risk of flooding, as the Southeast is experiencing with Debby.

TVA ‘clearly a laggard’ in renewable energy

This article was originally published by Tennessee Lookout.

ASHLAND CITY — When he heard about the sale, Kerry McCarver was perplexed.

In 2020, the mayor of rural Cheatham County discovered that the Tennessee Valley Authority bought about 280 acres of rolling farmland “in the middle of nowhere” in his county, which lies just west of Nashville and is home to about 42,000 people.

He asked another county official who formerly worked for the TVA, the nation’s largest public power company, to find out what it planned to do with the land.

The answer they got was “future use,” and they speculated a solar farm might be in the works.

“It’s kind of the last we thought about it,” McCarver said during an interview in his office in May. “Then a year ago last summer, TVA called here needing a place to have a public meeting.”

The authority was now proposing a 900-megawatt natural gas-fired power plant, battery storage, pipelines and other associated infrastructure for the site, which came as a shock to McCarver and many other locals who felt it was wholly inappropriate for the area.

Welcome to the Heat Dome

Written by

namheat geos5 20240619An area of high pressure lingered in the upper atmosphere over the U.S. Midwest and Northeast in June 2024. This pushed warm air toward the surface and trapped it there—a weather phenomenon meteorologists call a heat dome. The heat wave reached the Southern Appalachians, as seen in this model generated from NASA Earth Observatory data.  NASA

How climate change is heating up the weather, and what we can do about it

This article was originally published by The Conversation.

The heat wave that left more than 100 million people sweating across the eastern U.S. in June 2024 hit so fast and was so extreme that forecasters warned a flash drought could follow across wide parts of the region.

Prolonged high temperatures can quickly dry soils, triggering a rapid onset drought that can affect agriculture, water resources and energy supplies. Many regions under the June heat dome quickly developed abnormally dry conditions.

(The average temperature of June was about 7 degrees above normal in Knoxville as reported by Weather Underground).

The human impacts of the heat wave have also been widespread. In Ohio and Pennsylvania, emergency room visits for heat-related illnesses surged. Several Massachusetts schools without air conditioning closed to protect kids and teachers. In New York and New Jersey, electric wires sagged in the heat, shutting down trains into and out of New York City and leaving commuters stranded.
