American Petroleum Institute v. EPA

The American Petroleum Institute and other petitioners voluntarily dismissed a petition filed in 2012 to challenge Step 3 in EPA’s “tailoring rule,” which addressed thresholds for regulating greenhouse gas emissions from large stationary sources. The proceeding had been held in abeyance since 2013. The Supreme Court’s 2014 decision in Utility Air Regulatory Group v. EPA made the tailoring rule invalid.

The D.C. Circuit granted a motion requesting that this action be held in abeyance pending the U.S. Supreme Court’s disposition of Utility Air Regulatory Group v. EPA and related petitions.  The Utility Air Regulatory Group and numerous other parties filed petitions for writs of certiorari for review of the D.C. Circuit’s June 2012 decision in <a href="https://www.cadc.uscourts.gov/internet/opinions.nsf/52AC9DC9471D374685257A290052ACF6/$file/09-1322-1380690.pdf">Coalition for Responsible Regulation, Inc. v. EPA</a> that upheld EPA’s GHG permitting program for stationary sources and other EPA regulation of GHG emissions.
