The Obama administration made Phase 2 of the Green House Gas (GHG) a final rule from EPA and the National Highway Traffic Safety Administration in October 2016. The rule mandated that rebuilt engines installed in gliders satisfy emission standards in the year they were assembled applicable to new motor vehicle engines.
But late last month, EPA notified the Office of Management and Budget of its plans to issue a proposed rule for repeal.
Glider kits mix refurbished older components, including transmissions and pre-emission-rule engines, with a new frame, cab, steer axle, wheels and other standard equipment. Gliders are approximately 25% less expensive than new trucks, which can be a significant cost savings for small businesses and owner-operators.
Glider assemblers initially said Phase 2 — due to take effect Jan. 1 — would effectively shut down their industry. But this summer they filed a petition for reconsideration of the final rule.
Phase 1 of the GHG rule took effect in 2014. As of Jan. 1 this year, Phase 1 toughened emission limits of carbon dioxide and other greenhouse gases, and required truck makers to produce medium- and heavy-duty trucks with improved fuel mileage.
The truck and engine sections of Phase 2 will continue to be rolled out in 2021, 2024 and 2027.
