Preview: Supreme Court prepares to hear MATS oral arguments

Dive Brief:

• The U.S. Supreme Court will hear oral arguments on a major challenge to EPA toxic emissions rules this Wednesday, the Hill reports.
• A coalition of states and industries alleges that environmental regulators did not sufficiently consider the cost of reducing power plant emissions of mercury and other hazardous substances when it drafted the Mercury and Air Toxics Standard (MATS).
• More than 20 states have filed complaints saying that complying with the MATS rule would cost too much and force too many coal-fired facilities offline.
