  • Final Rule for Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles - Phase 2

The Environmental Protection Agency (EPA) is proposing to repeal the emission standards and other requirements for heavy-duty glider vehicles, glider engines, and glider kits based on a proposed interpretation of the Clean Air Act (CAA) under which glider vehicles would be found not to constitute “new motor vehicles” within the meaning of CAA section 216(3), glider engines would be found not to constitute “new motor vehicle engines” within the meaning of CAA section 216(3), and glider kits would not be treated as “incomplete” new motor vehicles. Under this proposed interpretation, EPA would lack authority to regulate glider vehicles, glider engines, and glider kits under CAA section 202(a)(1). A public hearing will be held in Washington D.C. on December 4, 2017.
