Ensure availability and sustainable management of water and sanitation for all

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.

Veterinary college takes precautionary measures due to bird flu resurgence

Sandra Harbison is a media relations specialist with the University of Tennessee College of Veterinary Medicine.

KNOXVILLE — High Pathogenic Avian Influenza (HPAI), a very contagious and often deadly disease of poultry, can result in the deaths of entire flocks within a matter of days. Also known as bird flu, HPAI has recently been detected in wildlife and poultry in Tennessee. This virus can spread quickly between birds, including birds that do not have any signs of disease. It has been reported to impact certain mammalian species, including humans, according to the Centers for Disease Control and Prevention. There is no treatment for HPAI, and the best prevention is to avoid sources of exposure.

Out of an abundance of caution, the University of Tennessee College of Veterinary Medicine (UTCVM) has made the difficult decision to temporarily halt the acceptance and treatment of injured or abandoned wild birds including raptors, songbirds or waterfowl (including owned waterfowl). This precautionary measure will help protect patients, faculty, staff and students from potential exposure to HPAI.

(The Tennessee Wildlife Resources Agency on Dec. 18 warned hunters, birdwatchers and poultry owners of increased bird flu risk. The CDCP as of Jan. 24 considers bird flu “widespread” in wild bird populations and reports limited outbreaks in poultry and livestock workers.)

kingston tm 2008357In the early morning hours of Dec. 22, 2008, the earthen wall of a containment pond at Tennessee’s Kingston Fossil Plant gave way. The breach released 1.3 million cubic meters (1.7 cubic yards) of sludge, infiltrating a nearby river and damaging dozens of homes.  NASA Earth Observatory

Journalist’s book offers deep sweep of 2008 coal-ash disaster at TVA’s Kingston coal plant

CHATTANOOGA — Jared Sullivan’s book, Valley So Low, is “A courtroom drama about the victims of one of the largest environmental disasters in US history — and the country lawyer who challenged the notion that, in America, justice can be bought.” Those words from the publisher’s dust jacket sum up the story, but the pathos of workers, certain that they got sick on the job, and the lawyer’s struggle against a well-funded corporate defense, is in the details.

Most residents of the Tennessee Valley remember the 2008 disaster when a wall of a coal ash slurry rushed out of the Kingston Steam Plant, flooding the Emory River and inundating 300 acres of the surrounding countryside. 

Sullivan offered insight into the story to an audience in Chattanooga in October. When workers fell ill after the cleanup, local personal injury lawyer Jim Scott challenged Jacob’s Engineering, a private company the Tennessee Valley Authority contracted to manage the cleanup. Scott was the only lawyer willing to take their case, according to Sullivan.

North Fork Wolf River 1536x1007A man paddles down the main stem of the Wolf River in West Tennessee. The state is working to purchase 5,477 acres of forest land near Grand Junction from the Hobart Ames Foundation. The land is part of the Wolf River watershed.  Wolf River Conservancy

The roughly 5,500-acre property features wetland forest used for research by the University of Tennessee

This article was originally published by Tennessee Lookout.

GRAND JUNCTION — About 60 miles east of Memphis near the Mississippi line, verdant hardwood trees and ecologically exceptional streams weave through thousands of acres of rolling hills.

The land is home to a diverse array of aquatic and terrestrial life, decades-old archaeological sites and a watershed that feeds into the aquifer where hundreds of thousands of Memphians source their drinking water.

If all goes to plan, 5,477 acres of this land will soon become Tennessee’s newest state forest, securing its preservation for posterity.

The land is a portion of the 18,400-acre historic Ames Plantation, a privately owned tract in Fayette and Hardeman Counties amassed by Massachusetts industrialist Hobart Ames in the early 1900s.

EPA should take over water protections in face of hostile legislature

Gray Jernigan is deputy director and general counsel for MountainTrue.

RALEIGH — MountainTrue is committed to safeguarding the public water resources of Western North Carolina. Our mission to protect the health of our waterways and the well-being of our communities has never been more critical. However, the obstacles we now face have made it clear that the state cannot meet its obligations under the Clean Water Act. 

Therefore, MountainTrue has joined the Southern Environmental Law Center, Cape Fear River Watch, Environmental Justice Community Action Network and the Haw River Assembly in filing a formal petition asking the U.S. Environmental Protection Agency to withdraw North Carolina’s authority to regulate water pollution. This action is necessary because the state legislature has crippled the NC Department of Environmental Quality’s ability to protect our waterways, drinking water sources and communities from harmful pollution.

The Duck landed third on American Rivers’ list of most endangered rivers in the U.S.

This story was originally published by Tennessee Lookout.

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.

Betty Boop recovered from drink during widespread river cleanup

KNOXVILLE Rain didn’t stop 441 volunteers from cleaning up the community’s waterways during the 35th annual Ijams River Rescue on March 9.

They tackled trash at 31 sites in Knox and Blount counties, filling 1,097 bags with garbage weighing an estimated 21,958 pounds (10.48 tons). That doesn’t include the weight of 46 tires and large items such as household appliances, furniture and car parts.

Plastic and Styrofoam waste was common in all areas, but Ijams River Rescue volunteers found items such as a robot puppy, drug paraphernalia, an antique lounge chair, a full patio set, suitcase, Betty Boop doll and shoes, sofas, stove parts, traffic barrels, a car seat, sports gear, a “nice watch” and a $10 bill.

RESCHEDULED: Mudchasers wanted: Sign up to track pollution and sediment pumps

Chris Irwin

KNOXVILLE — Join Chris Irwin and others to learn how to help track the origin of sediments and other pollutants in area waterways.

The meeting was postponed by snow and is now set for 7 p.m. Jan. 24 at Barleys, 200 East Jackson Ave., Knoxville.

“Spring is coming and with it rain and mud into the creeks and streams around Knoxville. We think a handful of people working together can stop a lot of mud going into the Tennessee River.

“This meeting is to show maps, a free app for gps pics, and a process to follow mud to its source so we can rat out the developers and others being sloppy with the health of our streams. We have the technology.”

By providing both mitigation and adaption, dam removal can lower greenhouse gas emissions and restore carbon sinks.

This article was originally published in The Revelator. Gary Wockner is an environmental activist, scientist and writer in Colorado.

As the climate crisis escalates, a huge amount of attention and money is being focused on climate solutions.

These can be divided into two categories: solutions that pursue “mitigation,” which lowers greenhouse gas emissions, and those that pursue methods to adapt to climate impacts to increase human and ecological resiliency.

Dams, of course, create enormous environmental harms, many of which have already been described in scientific literature. Equally well documented is the fact that removing dams can restore seriously damaged ecosystems. But missing from almost every climate-solution story and study is how dam removal can be key for both mitigation and adaptation.

Here are 10 reasons how dam removal fights climate change.

Salamanders are under siege in a changing world

Salamanders are extraordinary creatures. Some of these astonishing amphibians boast vibrant colors and patterns while two-thirds of all species are lungless and able to breathe through their skin. All salamanders have the remarkable ability to regrow limbs, tails, and even parts of their heart and brain, a rare ability in the animal kingdom. 

More salamander species live in the Appalachians than anywhere else in the world. Fifty-four species of salamander call Virginia home.

Roughly 20 percent of the world’s salamander species can be found in the South

Unfortunately, the impacts of climate change, habitat loss and pollution pose a real danger to these sensitive creatures. Increased temperatures, changing humidity levels, wildfires and droughts wreak havoc on salamanders, which are impacted by even small changes in habitat conditions and are often specialized to small native ranges. 

Southern Environmental Law Center’s work addressing climate change, fighting for clean water, and conservation efforts help protect all kinds of salamanders in the South. To celebrate the Endangered Species Act’s 50th anniversary, they are highlighting some of the endangered and threatened salamanders of our region.
