• Mexichem Fluor Inc. v. EPA (D.C. Cir. 2019 and 2017). We represented The Chemours Company in successive D.C. Circuit cases regarding the listing and delisting of chemical substitutes for ozone-depleting substances. Crowell attorneys authored a brief defending a regulation removing chemicals from the list of approved substitutes based on their global warming potential, and argued both cases.

• West Virginia v. EPA (D.C. Cir. en banc, argued 2016). We were the principal author of one set of petitioner-side merits briefs in this landmark challenge to the Obama Administration’s Clean Power Plan, and one of our partners was chosen by the challengers’ coalition to argue a significant portion of the case. A recent addition to our team from DOJ argued another part of the case for EPA.
