Glider Trucks

Glid­er kits are new truck chas­sis that are equipped with refur­bished diesel engines and pow­er­trains. They gen­er­ate 20 to 40 times high­er emis­sions than new trucks with new engines. In Octo­ber 2016, the Envi­ron­men­tal Pro­tec­tion Agency (EPA) con­firmed that glid­er kits qual­i­fy as motor vehi­cles that must meet new truck emis­sions requirements.

2017-2021

  • Novem­ber 2017

    After EPA Admin­is­tra­tor Pruitt met with the CEO of Fitzger­ald Glid­er Kits, the EPA issued a pro­pos­al in Novem­ber 2017 that would exempt glid­ers from air emis­sions require­ments, based on the asser­tion that glid­ers do not qual­i­fy as motor vehicles. 

  • Jan­u­ary 2018

    In Jan­u­ary 2018, Cal­i­for­nia Attor­ney Gen­er­al Xavier Becer­ra led a coali­tion of 12 states that filed com­ments oppos­ing the EPA’s attempt to exempt glid­ers from new truck emis­sions requirements.

  • July 2018

    Just before resign­ing in July 2018, EPA Admin­is­tra­tor Pruitt announced a de fac­to sus­pen­sion of the Octo­ber 2016 rule by stat­ing that the EPA would exer­cise its enforce­ment dis­cre­tion and decline to imple­ment the rule. With­in a week, Attor­ney Gen­er­al Becer­ra joined with 12 oth­er attor­neys gen­er­al in writ­ing a let­ter to Act­ing EPA Admin­is­tra­tor Andrew Wheel­er request­ing that the EPA with­draw or issue an admin­is­tra­tive stay of the de fac­to suspension.

    In their let­ter, the attor­neys gen­er­al argued that the de fac­to sus­pen­sion is unlaw­ful as it will allow man­u­fac­tur­ers of non-emis­sion com­plaint glid­er vehi­cles and kits to raise pro­duc­tion many times beyond the lev­el that is oth­er­wise per­mis­si­ble. They also assert­ed that the EPA did not com­ply with the pro­ce­dur­al require­ments for sus­pend­ing a rule. The let­ter indi­cat­ed that the attor­neys gen­er­al were pre­pared to chal­lenge the de fac­to sus­pen­sion in court.

  • July 2018

    A few days after the attor­neys gen­er­al sent the let­ter to Act­ing EPA Admin­is­tra­tor Wheel­er, the D.C. Cir­cuit Court of Appeals issued an emer­gency stay of the de fac­to sus­pen­sion of the Octo­ber 2016 rule. Then, as the EPA had failed to act on the let­ter from the attor­neys gen­er­al, Attor­ney Gen­er­al Becer­ra and a coali­tion of 15 oth­er attor­neys gen­er­al also filed suit in the D.C. Cir­cuit, chal­leng­ing the de fac­to sus­pen­sion as both sub­stan­tive­ly and pro­ce­du­ral­ly unlawful.

  • July 2018

    A week lat­er Act­ing Admin­is­tra­tor Wheel­er acknowl­edged EPA lacked the legal author­i­ty for the de fac­to sus­pen­sion of the 2016 rule and with­drew the sus­pen­sion. How­ev­er, the EPA is con­tin­u­ing to advance its Novem­ber 2017 pro­posed rule to exempt glid­ers from air emis­sions requirements.
