The U.S. Environmental Protection Agency (EPA) is being taken to court by the Center for Biological Diversity, the Center for Environmental Health, and the Sierra Club for its alleged neglect in updating air quality standards, particularly concerning nitrogen pollution.
The Clean Air Act mandates the EPA to evaluate and, if necessary, amend Pollution standards every five years to ensure public health protection. Despite this directive, these conservation groups assert that the EPA has not re-evaluated its standards since May 2018 and hasn’t made any amendments since 2010. This is concerning, especially given emerging scientific data highlighting the increased risks associated with nitrogen Pollution to both humans and the environment.
Ryan Maher, an environmental health attorney at the Center for Biological Diversity, stated, “The EPA’s disregard for the Clean Air Act jeopardizes public health and our environment. This failure to adhere to their responsibilities, especially when the consequences impact people nationwide, is not only dangerous but also unlawful. We are now turning to the judiciary to ensure the EPA respects and enforces the law.”
One of the significant causes of nitrogen pollution is the combustion of fossil fuels in vehicles and power plants. This type of Pollution has been connected to numerous health problems in humans, including heightened risks of lung and heart diseases, birth defects, diabetes, cancer, and even mortality. Moreover, excessive nitrogen Pollution can lead to high nitrate levels in water, resulting in toxic algae blooms detrimental to both the environment and wildlife. This pollutant can also lead to the formation of smog, as well as soil contamination.
Joshua Smith, a senior attorney at the Sierra Club, emphasized the urgent need for updated standards. He said, “The scientific evidence has consistently shown the dire public health implications of nitrogen oxide Pollution. However, the protective measures that should keep communities safe remain outdated and ineffective. It is time for us to ensure that our Pollution standards are commensurate with scientific findings and offer the protection our communities are entitled to.”
Current research suggests that the adverse health effects linked to nitrogen Pollution have become even more evident since the EPA’s last standard update in 2010. Connections have been made between exposure to nitrogen Pollution and increased dementia risks, even at levels lower than the prevailing standards. Furthermore, nitrogen Pollution exposure has been associated with both depression and exacerbated outcomes for COVID-19 patients.
These Conservation groups hope for the court to recognize the EPA’s violation of the Clean Air Act and compel the agency to undertake its obligatory duties.
Kaya Allan Sugerman, the director of illegal toxic threats at the Center for Environmental Health, expressed frustration over the EPA’s procrastination. “When the checks on Pollution are outdated, both the environment and the public suffer. The EPA has a duty to update these essential health standards, and it is regrettable that legal action is required to make the agency adhere to the law,” Sugerman remarked.
