San Francisco takes on the EPA in a case about poop and a $10 billion fine

The city of San Francisco is challenging the Environmental Protection Agency (EPA) in a legal case centered around sewage treatment and a potential $10 billion fine. This complex issue has arisen due to disagreements on how the city manages wastewater and stormwater.
