On March 28, 2017, President Donald Trump signed an executive order (EO) directing executive departments and agencies to review regulations that potentially burden the development or use of domestically-produced energy resources. This EO sets the stage for what could become a series of sweeping reversals of the Obama Administration’s greenhouse gas (GHG) reduction and climate change polices. In particular, the order lays the groundwork for reform of the Clean Power Plan (CPP) and the new source pollution standards for new, modified and reconstructed power plants (NSPS).
The issuance of this EO kicks off a long and complex process for EPA to review both the CPP and NSPS, draft and publish proposals to revise or rescind the rules, accept notice and comment on the proposals, address comments on the proposals, and then issue final rules. Regardless of whether EPA proposes to suspend, revise, or rescind the rules, legal challenges are sure to follow. The outcome of these rulemakings and subsequent litigation will be consequential for the future of federal regulation of GHGs under the Clean Air Act (CAA).
