EPA signed that triggered a public hearing and comment process in order to consider three separate requests for waiver of preemption from the California Air Resources Board. The Notices are associated with CARB’s most recent on-highway heavy-duty vehicle emission regulations and pertain to: 1) HD emission warranty regulations; 2) Advanced Clean Truck regulations (this waiver request also includes CARB’s zero emission airport shuttle rule and zero-emission powertrain certification regulations); and the 3) Omnibus Low NOx regulations.
