Norfolk Southern agrees to $310 million settlement over Ohio train derailment

By Shannon Kelleher

Norfolk Southern Corp. on Thursday announced it will pay more than $300 million to resolve investigations by three US agencies in the aftermath of a catastrophic train derailment last year that contaminated the town of East Palestine, Ohio with toxic chemicals.

The settlement resolves “all claims and investigations” by the US Environmental Protection Agency (EPA), the Department of Justice (DOJ), and the US Department of Interior arising from the February 2023 derailment in which 38 train cars carrying vinyl chloride and other hazardous chemicals ran off the tracks in northeastern Ohio.

The EPA said the company had agreed to the following:

Spending $235 million on past and future cleanup costs
Paying a $15 million civil penalty for violations of the Clean Water Act
Paying $25 million for a 20-year community health program that includes medical monitoring and mental health services.
Spending approximately $15 million to implement long-term monitoring of groundwater and surface water for a period of 10 years.
Paying $15 million for a private drinking water monitoring fund that will continue the existing private drinking water well monitoring program for 10 years.
Paying an estimated $6 million to implement several environmental remediation projects.

Norfolk Southern additionally said it would repay the EPA $57 million for response expenses and will spend $244 million on safety initiatives. These will include new monitoring devices along its tracks and better alarms for detecting overheated wheel bearings, according to the EPA.

“We are very, very pleased that Norfolk Southern has agreed to settlement terms that hold them accountable for disrupting the lives of the people of East Palestine, and help to bring some justice and a path towards closure to those who were affected by this disaster,” Rebecca Chattin Lutzko, interim US Attorney for the Northern District of Ohio, said during a press conference on Thursday. “This settlement communicates to other, similar companies that they must take full responsibility for their actions.”

Toxic vinyl chloride accidents happen once every five days, report finds

By Dana Drugmand

Accidental releases of toxic vinyl chloride have occurred in the United States once every five days, on average, since 2010, according to a new report that highlights the extent to which communities and chemical plant workers are exposed to the known carcinogen.

The findings add to a growing body of evidence on the frequency of hazardous chemical accidents, including a 2023 report that found such incidents occur in the US almost daily.

Environmental, public health and community advocates have been calling on the US Environmental Protection Agency (EPA) to ban vinyl chloride following a February 2023 train derailment in East Palestine, Ohio, which resulted in a “controlled” combustion of vinyl chloride in several rail cars that exposed residents to the chemical.

The report, produced by Material Research L3C on behalf of the environmental groups Beyond Plastics and Earthjustice, is intended to help inform the EPA as it takes steps towards conducting a risk assessment of vinyl chloride, along with four other toxic chemicals, a move the agency announced in December. The review, conducted under the Toxic Substances Control Act (TSCA), would be the first step towards considering a potential ban on vinyl chloride or additional restrictions to help protect public health and the environment from exposure to the chemical.

In public comments to the EPA, the groups Beyond Plastics, Earthjustice, and Toxic-Free Future urged the agency to quickly move to designate vinyl chloride as a “high priority substance” so that it can begin the risk evaluation.

EPA moves to limit frequent chemical accidents

By Shannon Kelleher

Hundreds of chemical facilities around the US must implement new procedures to try to better safeguard communities from accidents that are happening with alarming frequency and jeopardizing human and environmental health.

New measures announced Friday by the Environmental Protection Agency (EPA) require industrial operators to “prevent accidental releases of dangerous chemicals that could otherwise cause deaths and injuries, damage property and the environment, or require surrounding communities to evacuate or shelter-in-place.”

The final rule, which amends the EPA’s Risk Management Program (RMP) that applies to plants dealing with hazardous chemicals, asks facilities to evaluate the risks of natural hazards and climate change, makes information about chemical hazards more accessible for people living near these facilities. The rule also allows for plant employees to stop working when they think there is a potential hazard.

This new requirements are expected to reduce the frequency and severity of accidents, building on revisions proposed in 2022. They provide the most protective safety provisions for chemical facilities in the EPA’s history, EPA deputy administrator Janet McCabe said on a press call.

Accidental releases of chemicals from industrial facilities cost the US more than $540 million each year, McCabe said on the press call, not including major catastrophes that can individually cost much more.

Texas farmers, watchdog group demand EPA act on PFAS in farm fertilizer

By Shannon Kelleher

In the wake of fresh evidence that US farms are being poisoned by PFAS-laden fertilizers, a watchdog group and two Texas farm families said Thursday they plan to sue regulators to try to force protective actions.

The Environmental Protection Agency (EPA) has violated the Clean Water Act by failing to regulate at least 12 per- and polyfluoroalkyl substances (PFAS) in treated sewage sludge (biosolids) applied to agricultural lands, allege Public Employees for Environmental Responsibility (PEER) and the farmers in a notice of intent to sue sent Feb. 22 to EPA Administrator Michael Regan. Studies have linked these particular PFAS chemicals to asthma, disrupted thyroid hormones, immune suppression, kidney problems, lung issues in children, and other health effects, the letter says.

The agency has also unlawfully failed to include in its regular biosolids reports at least 18 additional PFAS chemicals that scientific studies indicate are present in biosolids, PEER and the farmers allege.

PEER and the farmers will sue the EPA within 60 days if the agency does not take immediate action, said PEER executive director Timothy Whitehouse in the notice of intent to sue.

“EPA has deemed it acceptable for biosolids containing PFAS and other known toxic chemicals to be applied directly to soil as fertilizer, where these man-made contaminants then build up in the environment, exacerbating the PFAS contamination crisis,” wrote Whitehouse. “This is not protective of human health or the environment.”

“Because there are no standards, farmers, ranchers, and gardeners have no warning that they are potentially poisoning their soil, water, livestock, and pets with these biosolid fertilizer products,” Kyla Bennett, director of science policy for PEER, said in a press release. “Prompt, responsible regulatory action by EPA would prevent untold damage and heartache.”

Pesticide-treated seeds harm earthworms, study finds

By Shannon Kelleher

Commonly used pesticides pose a toxic threat to earthworms, creatures considered crucial for the health of soil used to grow crops, according to a new study published Wednesday.

The study builds on evidence that a class of insecticides called neonicotinoids, or neonics, are harming a range of species important for planetary health. Neonics have been banned in many countries but are popular with farmers in the United States.

The authors of the new study said they found that when earthworms were exposed to four different types of neonics, as well as the fungicide difenoconazole, they suffered damage to their mitochondrial DNA and gained significantly less weight than earthworms not exposed to the chemicals. The pesticides were especially damaging when the worms were exposed to a neonic plus the fungicide in combination.

The findings were published in the journal Environmental Science & Technology Letters.

“We need to re-evaluate the toxicity of neonics and the synergistic effects of neonics and systemic pesticides in those non-target organisms when they are applied to soil simultaneously,” said Chensheng (Alex) Lu, a professor at Southwest University in Chongqing, China and an author of the study.

“The contribution of earthworms to crop yields is as essential as pollination done by honey bees,” he added. “A healthy soil is simply not possible without the presence of earthworms.”

EPA proposes adding PFAS to hazardous waste cleanup law

By Shannon Kelleher

Federal regulators today announced a proposal to update the definition of hazardous waste in the Resource Conservation and Recovery Act (RCRA) to include a class of chemicals known as PFAS, a move designed to help ensure cleanups of these so-called “forever chemicals” at hazardous waste facilities.

The Environmental Protection Agency (EPA)’s proposed rules will also add nine per- and polyfluoroalkyl substances (PFAS) to a list of substances in the act that are considered in assessments of facilities used to treat, store, and dispose of hazardous waste. The updates will strengthen protections for communities located near the 1,740 hazardous waste facilities across the US, the Environmental Protection Agency (EPA) said in a statement.

“Today’s announcement by the EPA will ensure that quick action can be taken to clean up PFAS and will send a powerful signal to industry to be good stewards of their PFAS wastes,” said Scott Faber, senior vice president for government affairs at The Environmental Working Group nonprofit in a statement.

PFAS chemicals do not break down naturally and can leach into drinking water from industrial sites, sewage treatment plants, and landfills. PFAS have been found in at least 45% of US tap water and in the blood of about 97% of Americans. Exposure to the chemicals has been linked to numerous health problems, including certain cancers.

Over 700 military sites nationwide have been either found to have discharged or are suspected of having discharged PFAS into the environment, often from firefighting foam that contains the toxic chemicals.

Heavy metal exposure linked to problems for middle-aged women

By Shannon Kelleher

Women with higher exposure to heavy metals may have fewer eggs in their ovaries as they near menopause compared to others the same age, a condition linked to hot flashes, weak bones, heart disease, and other health problems, according to a new study in more than 500 middle-aged women.

Exposures to cadmium, arsenic, and mercury, in particular, were linked to lower levels of a hormone that strongly correlates with the number of eggs left in a woman’s ovaries, according to the study, which was published Jan. 25 in The Journal of Clinical Endocrinology & Metabolism.

“Our findings suggest that even low exposure to these ubiquitous metals may influence women’s reproductive health,” said Sung Kyun Park, a professor of epidemiology and environmental health science at the University of Michigan and an author of the study.

“Although individual women may reduce exposure by avoiding foods contaminated with toxic metals and limiting the use of the known sources of metals, a more important approach is to reduce exposure at the population-level through legislation and regulations,” he added.

While heavy metals are known to have toxic effects on the reproductive system, little research has investigated whether exposure to low levels of these metals can influence how many eggs women have in their ovaries as they approach menopause, which begins for most women between the ages of 45 and 55.

“Epidemiological evidence is scanty,” said Park, noting that studies relying on animal models have shown a potential link between toxic metals and altered ovarian function.

Research ramps up but PFAS pollution remains tough to tackle

By Shannon Kelleher

As researchers rush to tackle global contamination from a class of toxic chemicals known as PFAS, a new study demonstrates a novel way to detect the substances in wastewater – but also underscores how far scientists are from figuring out how to effectively overcome this worldwide threat to human and environmental health.

The new method makes use of a sensor to identify one type of per- and polyfluoroalkyl substances (PFAS) called perfluorooctanoic acid (PFOA) in heavily contaminated water based on changes in light emissions from metals on the device’s surface, according to a Jan. 16 study in the journal Analytical Chemistry. The researchers plan to develop the early model in to a portable device, according to a press release.

Current PFAS detection methods take place in a laboratory using a tool called a mass spectrometer, which charges molecules in a sample and then accelerate them using magnetic or electric fields so that scientists can identify them.

“Existing approaches are time-consuming,” said Zoe Pikramenou, a professor at the University of Birmingham in the United Kingdom who is an author of the study. “Our approach offers significant advantages of greater speed, ease of analysis, and reduced cost over currently-used methods.”

The prototype can so far only measure one PFAS chemical out of thousands. And although the sensor appears to be sensitive enough to illuminate PFAS in industrial wastewater, it may take another decade before the technology can be used for drinking water, which contains much lower levels of the chemicals, said Pikramenou.

Many other promising new technologies to detect so-called “forever chemicals”, which do not naturally break down, remain in the early stages of development. The Biden administration has called on federal agencies to restrict PFAS from entering US water, air, land, and food; set goals for the government to better assess and reduce PFAS exposure; clean up existing pollution; and expand health effects information.

Doctors raise alarm on dropping global fertility rate, environmental pollutants cited

By Shannon Kelleher

Health researchers from around the world are sounding an alarm on a persistent drop in fertility rates, pointing to environmental pollutants among a wide range of factors that they argue need to be urgently addressed in a paper published Wednesday.

Both male and female reproductive health is deteriorating, especially in industrialized regions, suggesting important roles of environmental factors, such as endocrine-disrupting chemicals and pesticides, the authors of the paper state. Studies indicate that the global fertility rate is dropping, with 93% of all countries worldwide expected to dip below levels necessary to keep populations from shrinking by 2100.

The trend is driven, in part, by the impacts of exposure to toxic chemicals, as well as lifestyle factors such as smoking and obesity, according to the 11 researchers authoring the paper, which was published Wednesday in the journal Human Reproduction Update. The researchers – who come from multiple countries, including the United States, Australia, South Africa, Greece, and Denmark – reviewed dozens of studies in coming to their central conclusion that public policy, research and medical access must be stronger on the topic of fertility.

In conjunction with the publication of the paper, the International Federation of Fertility Societies (IFFS), which represents fertility societies in 65 countries, is launching a global campaign Wednesday seeking to push policymakers to make fertility care more affordable, accessible, and equitable, and to adopt policies that aid fertility, including reducing exposures to air pollution and other harmful chemicals linked to reproductive harm.

The paper says that “due to multiple societal and environmental changes, it is important to emphasize that globally between 48 million couples and 186 million individuals of reproductive age live with infertility.” They call infertility “a common chronic disease affecting many reproductive-age women and men.”

Data on the decline in total fertility rate around the world – the number of children each woman gives birth to, a critical factor in population growth – is “pretty remarkable,” said Tracey Woodruff, a professor at the University of California, San Francisco School of Medicine who was not involved in the paper.

“This is really an important issue because it impinges on people’s ability to choose pregnancy should they want to choose pregnancy,” said Woodruff

Among environmental pollutants, endocrine-disrupting chemicals, in particular, are a fertility concern, she said. “We know that the number and amount of them are increasing and we know that some of them can directly impact male and female reproductive health.”

It is difficult to fully calculate the role of environmental pollutants in infertility since “we only have data on a very small proportion of endocrine-disrupting chemicals to which we’re exposed,” she added.

About one in six people struggle with infertility, according to the World Health Organization. Research suggests sperm count in men has declined by 1.6% per year since 1973, although the impact on global fertility is unknown, the paper states.

EPA data shows US toxic PFAS waste problem is worsening, watchdog group says

By Shannon Kelleher

The average amount of waste containing toxic PFAS chemicals that is shipped around the US each month has almost quadrupled since 2018, according to an analysis of government data by a watchdog group.

The Environmental Protection Agency (EPA) data points to about 10,344 shipments totaling almost 27 million kilograms of per- and polyfluoroalkyl substances (PFAS) waste in the last five years, since the agency first began collecting the data.

The findings, released Nov. 9, reflect “a small percentage, we believe, of the amount of PFAS waste that is being generated, transported, stored, and disposed of in the US,” said Tim Whitehouse, executive director of the watchdog group Public Employees for Environmental Responsibility (PEER), which authored the report. “There’s no reporting requirement.”

The EPA data supports the need for the agency to regulate PFAS under the Resource Conservation Recovery Act (RCRA) Subtitle C, which authorizes the agency to set regulatory standards for the management of hazardous waste from “cradle to grave,” says the report. PEER and the Environmental Law Clinic at Berkeley, on behalf of the Green Science Policy Institute and community groups around the country, petitioned the EPA in 2019 and 2020 to regulate PFAS as hazardous waste.

The EPA did not respond to request for comment.

Exposure to PFAS “forever chemicals,” which do not break down naturally, has been linked to health problems including thyroid, kidney, and testicular cancer, as well as ulcerative colitis, high cholesterol, and hypertension during pregnancy. About 97% of Americans have PFAS in their blood, according to the Centers for Disease Control. People are exposed to the chemicals in water or food, the air they breathe, or from using products made with PFAS.
