The U.S. Supreme Court is forcing a do-over by the EPA on costly Clean Air Act regulations for power plants. According to NPR, industry representatives and 23 states argued against the current rules, which would cost $9.6 billion dollars a year. The benefits mainly consist of limiting the amount of mercury released into the air, which is then easily absorbed by fish and other animals low on the food chain, and then by humans. The EPA estimates that 7 percent of American women are exposed to dangerous amounts of the toxin, which is known to cause developmental issues in fetuses. The New York Times reports that the EPA will be allowed to enforce the current rules while it examines the costs and benefits and rewrites the regulations.
