Supreme Court “Not Willing to Stand on the Dock and Wave Goodbye” as EPA Explores How It Can Regulate Greenhouse Gases from Every Possible Source
In 2007, the Supreme Court told the U.S. Environmental Protection Agency (EPA) it was wrong to conclude that it lacked the authority to regulate greenhouse gases (GHGs) emitted from vehicles, because GHGs are an “air pollutant.” Since then, the energy and power industries in particular have watched as the EPA took that ruling and developed regulations focused on limiting GHG emissions from stationary sources. EPA not only regulated GHGs from utilities, but expanded the program to almost any source of GHGs (landfills, electronics manufacturers, office buildings), and then “tailored” the rule to limit what everyone agreed were onerous and unnecessary impacts. In a 5-4 decision, the Supreme Court again reversed the EPA, this time telling it that it cannot regulate entities’ GHG emissions if they do not otherwise need a Clean Air Act (CAA) permit. While the decision provides relief to building owners, hospitals, bakeries, dry cleaners, many manufacturers, and just about every other type of business that uses heating and air conditioning, the power industry itself (meaning those that need CAA permits anyway) did not fair as well because the Court upheld EPA’s authority to require them to implement “best available control technology” (BACT) to limit GHGs. This alert describes the decision, and addresses the question most relevant to the regulated community: How much will this decision matter? Read More
