Over the past 50 years, tremendous progress has been made in reducing air pollution under the Clean Air Act. Nevertheless, while air quality has improved greatly for much of the nation, there are still places where the goal of attaining national standards has still not been reached. This is often true in urban locations that are affected by multiple pollution sources; typically, these areas are also environmental justice communities. Recent events have called attention to the urgent need for concrete action to address the many problems of these communities.

With a contentious presidential election looming amidst a pandemic, economic worries, and historic protests against systemic racism, climate action may seem less pressing than other challenges. Nothing could be further from the truth.

In County of Maui v. Hawaii Wildlife Fund, the U.S. Supreme Court held, 6-3, that the Clean Water Act requires a national pollutant discharge elimination system permit “when there is the functional equivalent of a direct discharge.” The Court also decided Atlantic Richfield Co. v. Christian, holding, 7-2, that landowners adjacent to a Superfund site were potentially responsible parties under the Comprehensive Environmental Response, Compensation, and Liability Act.
