Clean Air

In the United States, low income Black and Brown communities are already more likely to suffer the impacts from permitted pollution from petroleum facilities and other polluting industries. In addition to these known and well documented disparities, regulators have allowed for even more pollution to be released onto these overburdened communities through regulatory loopholes in the Clean Air Act known as Startup, Shutdown, Malfunction, (SSM) leaving communities exposed to dangerous levels of toxic air pollution from multiple sources. Sierra Club and partners are working to ensure EPA implements strong rule-making that eliminates SSM loopholes and prioritizes the most impacted people by upholding equal protection laws. Dozens of community and environmental groups have called on President Biden to close SSM loopholes and end free passes to pollute.

EPA allows facilities like power plants and factories to emit as much pollution as they like during periods of Start-up, Shutdown, and Malfunctions. The amount of pollution emitted during so-called “SSM events” can be 100s to 1000s of times higher than normal operations.





Did you know that there are deadly loopholes in the EPA and state Clean Air Act rules? The Startup, Shutdown, and Malfunction loopholes allow polluters to ignore their permitted emission limitations -- and of course they take advantage of this! The consequences are even more deadly air pollution dumped on communities near plants and factories -- who already suffer the greatest burden from these poisons. It's time to close the loopholes! The Sierra Club has partnered with Earthjustice and community activists to create a video to shed light on this issue, and galvanize action to close the SSM loopholes.
