Today, Earthjustice—on behalf of Clean Power Lake County and other environmental and health advocacy groups—sent a 60-day Notice of Intent to sue the U.S. Environmental Protection Agency (EPA) over the agency’s inaction to regulate harmful carcinogenic air emissions from ethylene oxide (EtO) facilities as the law required.

The Clean Air Act directs the EPA to review its EtO standards every eight years. However, the agency has repeatedly missed this deadline—first in 2014 and again in April 2022.

The EPA admits the chemical is 60 times more toxic than previously estimated and that facilities that emit EtO, including commercial sterilizers and chemical manufacturers, pose an elevated cancer risk to nearby communities. Children are particularly sensitive to ethylene oxide when exposed.

Ethylene oxide is a colorless, typically odorless, flammable gas used to sterilize medical equipment and in the production of chemicals needed for antifreeze, plastics, detergents, and adhesives. It is one of the most toxic air pollutants EPA regulates. This toxic chemical is a known carcinogen to humans, especially when inhaled.

Facilities that emit ethylene oxide are typically found in low-income neighborhoods and communities of color, many already grappling with elevated toxic exposure and health risks from multiple forms of industrial pollution.

“EPA has delayed for too long to update sterilizer rule while communities suffer unnecessary toxic exposure and unacceptable cancer risks,” said Earthjustice attorney Marvin Brown. “Congress passed the Clean Air Act to protect communities from the harmful effects of air pollution, and tasked EPA with ensuring that industry emissions do not threaten public health. By failing to timely revise its sterilizer rule, EPA has left communities to fend for themselves against a deadly, cancer-causing chemical. We are calling on the EPA to finally remedy this injustice without further delay.”

As each day passes, ethylene oxide threatens the health of many communities that continue to wait on EPA to fulfill its legal obligations under the Clean Air Act. Today’s letter provides notice that community and environmental groups cannot wait any longer—and will sue EPA to compel the agency to enact stronger, science-based standards that are protective of public health.

“Excuse after excuse has led to death after death and EPA refuses to act. The agency waited more than eight years after the first deadline, and now missed a second deadline to properly regulate ethylene oxide, even as it recognized that the chemical was causing cancer to people in communities across the country,” said Raul Garcia, legislative director of Healthy Communities at Earthjustice. ”Our letter intends to compel long overdue protective action from EPA, but should also serve as reminder to state and local officials that their inaction is leaving people exposed to severe risk of cancer and other illnesses in the very communities they serve. Cancer-causing chemicals must be properly regulated at every level of government immediately.”

“The EPA’s mission is to protect human health and the environment. They are failing my community and communities across the country with their inaction to regulate harmful air emissions from ethylene oxide facilities. It’s unacceptable that everyday community members have been forced to file this suit in order for the EPA to be accountable and update their standards as required by law. Our rights have been violated and the EPA must do its job,” said Celeste Flores, steering committee member with Clean Power Lake County.

Earthjustice filed the Notice of Intent on behalf of Rio Grande International Study Center, Clean Power Lake County, California Communities Against Toxics, Union of Concerned Scientists, and the Sierra Club.

CPLC, allies sue EPA for exempting half a billion tons of toxic coal ash from health protections

Clean Power Lake County and other environmental, civil rights, and community groups today filed a lawsuit against the Environmental Protection Agency (EPA) in federal court for letting hundreds of toxic coal ash landfills off the hook from complying with important federal health and environmental protections.

Earthjustice mined databases buried in EPA archives and found that the agency exempted at least half a billion tons of coal ash in nearly 300 landfills in 38 states from standards designed to protect people from cancer-causing chemicals. The landfills are sited disproportionately in low-income communities and communities of color (see map). It is enough coal ash to fill train cars that could go around the earth two times.

Plaintiffs’ Attorney Mychal Ozaeta from Earthjustice said, “Power plant records reveal that about half of the toxic coal ash waste in the US is entirely exempt from any federal health protections. This is outrageous. The coal power industry is poisoning drinking water sources and the air we breathe while causing global warming.”

When the EPA adopted the first-ever rules in 2015 for toxic ash generated when burning coal, the agency excluded coal ash landfills and waste piles that stopped receiving new waste before the law went into effect. It also didn’t cover landfills at power plants that had already stopped producing power.

On August 1, more than 100 organizations in dozens of states and Puerto Rico wrote to the EPA urging them to stop exempting these abandoned landfills filled with coal ash (which is also known as “coal combustion residuals” or “CCR”).

The EPA has noted that the risks to humans associated with exposure to coal ash include “cancer in the skin, liver, bladder and lungs,” “neurological and psychiatric effects,” “cardiovascular effects,” “damage to blood vessels,” and “anemia.”

The lawsuit says what we know about the extent of water contamination from coal ash “is just the tip of the iceberg.”

The suit describes an Environmental Integrity Project and Earthjustice study of industry data: “Groundwater contamination exceeding federal health-based standards was found at 76% of the regulated CCR [coal combustion residuals] landfills. Regulated landfills are newer and more likely to be lined than the older landfills EPA exempted from the CCR rule. Thus, the exempted inactive CCR landfills are likely to be releasing even higher levels of toxic contaminants.”

The lawsuit states, “Coal-fired power plants generate one of the largest toxic solid waste streams in the United States. In this voluminous waste stream are large quantities of heavy metals and metal compounds such as arsenic, boron, cadmium, chromium, cobalt, lead, lithium, mercury, molybdenum, radium, selenium, and thallium.”

Nonprofit legal organization Earthjustice filed the lawsuit in US District Court in Washington, DC, on behalf of plaintiffs Statewide Organizing for Community eMpowerment (Tennessee), Indiana State Conference and LaPorte County Branch of the National Association for Advancement of Colored People, Hoosier Environmental Council (Indiana), Sierra Club, Clean Power Lake County (Illinois), and Environmental Integrity Project.

Among the hundreds of landfills the EPA has exempted from their protections is NRG Energy’s Waukegan Generating Station, where an unregulated coal ash fill has been contaminating groundwater since at least 2010.

“For years we have fought hard for our community to be protected, for our community to be respected and for our community to be seen,” said Dulce Ortiz, co-chair of Clean Power Lake County. “For starters, this can be done by ensuring the EPA protects our community by addressing the coal ash landfill that sits on our lakefront. Minority and economically disadvantaged communities are disproportionately burdened by pollution and the Waukegan community is no different. The EPA must do what it was intended to do, to protect our community residents and our environment.”

Sierra Club Attorney Bridget Lee said, “The continued storage of toxic coal ash in unlined landfills without groundwater monitoring flies in the face of EPA’s own science and risk assessments and threatens fenceline communities across the country. The agency must act now to close this dangerous loophole.”

According to the lawsuit, if the EPA had followed the law (the Resource Conservation and Recovery Act), “basic safeguards would be in place for inactive CCR landfills that would keep coal ash toxins out of our drinking water, air, rivers, lakes, and streams, and require remediation at the scores of sites already known to be contaminating water at dangerous levels.”
