Oakland, Calif.— The Center for Biological Diversity and Sierra Club filed notice today of their intent to sue the Environmental Protection Agency for failing to ensure that areas in 11 states and two U.S. territories have effective plans for cleaning up sulfur dioxide air pollution.
More than 1.6 million people live in these areas, which have sulfur dioxide pollution high enough to harm human health and the environment.
“The EPA’s delay in cleaning up this harmful air pollution not only endangers the health of hundreds of thousands of people but also encourages ongoing use of dirty coal and oil,” said Ryan Maher, an attorney at the Center for Biological Diversity. “These delays amount to illegal subsidies for fossil fuels, and they’re only going to slow our transition to a clean energy economy.”
The Clean Air Act requires the EPA to set national ambient air quality standards to protect people and the environment from pollutants like sulfur oxides. When those standards are violated, the agency must ensure that states have valid plans in place to clean up the pollution.
“Action to address sulfur dioxide pollution in these toxic environmental hotspots is long overdue,” said Zachary Fabish, a Sierra Club attorney. “The EPA must be held accountable to its statutory obligations to preserve and restore local air quality.”
The largest source of sulfur air pollution is the combustion of fossil fuels by power plants. Sulfur dioxide is also produced during industrial processes, such as extracting metal from ore and oil refining, and by ships, cars and heavy equipment that burn fossil fuels.
Some of the primary sulfur dioxide sources at issue in today’s notice include Arizona’s two copper smelters; coal-fired power plants in Kentucky, Tennessee and Texas; an aluminum smelter in New York; and chemical plants in Indiana and Louisiana.
Other areas suffering from air pollution covered by today’s notice are located in Guam, Illinois, Maryland, Michigan, Puerto Rico and Virginia.
Pollution associated with sulfur dioxide causes a range of public health and environmental problems. According to the EPA, exposure to sulfur dioxide air pollution can harm human health in as little as five minutes, triggering asthma attacks and harm to the lungs and cardiovascular system that can be fatal.
Today’s notice is part of the two groups’ ongoing work to compel the EPA to protect human health and the environment from sulfur pollution in accordance with the Clean Air Act’s requirements.
