What is the "Mercury and Air Toxics Standard?"

This was the rule in question in Michigan v EPA. It was passed in 2012 - here's a description of it:

The 2012 mercury and air toxics standards, which apply to about 600 power plants, established emissions limits for mercury, filterable particulate matter as a surrogate for toxic metals, and hydrogen chloride as a surrogate for acid gases. The EPA estimates that the standards will cost the power industry $9.6 billion annually.

The simple issue the court ruled on - and was divided over - was whether the benefits from the rule were compatible with the $9.6 billion cost. The majority said it didn't, the minority said it did.

The rulemaking process is discussed in both 2305 and 2306 in the sections on the executive branch - especially the bureaucracy.It's the mechanism through which laws are clarified so that they can be implemented by the appropriate agency.

The Supreme Court argued that these rules did not properly take into consideration the costs imposed on industry and that a lower court had to re argue the case with that in mind.
