The U.S. Environmental Protection Agency (EPA) is facing growing pressure to restrict the use of glider kits under the second phase of rules to control Greenhouse Gas emissions., according to Heavy Duty Trucking magazine.
The EPA announced in November that it was repealing the glider provisions in 2016 GHG rules, stressing that the gliders are not “new motor vehicles”, and the engines are not “new motor vehicle engines, Heavy Duty Trucking magazine reports.
In a teleconference on Monday, the U.S. Environmental Defense Fund challenged that, saying the position is against the principles of the Clean Air Act.
“For EPA to propose an interpretation of the Clean Air Act that would exclude these extremely high-polluting trucks from emissions standards is not only an unreasonable reading of the plain text of the CAA, it’s also at odds with and severely undermines the core purpose of the Clean Air Act,” said Alice Henderson, Environmental Defense Fund attorney.
The group is not alone in the fight. Executives from Volvo, Cummins, and Navistar said in a letter last year that the glider kits should not be used as a tool to bypass currently certified powertrains. Attorney generals from California, Connecticut, Illinois, Maryland, Massachusetts, New Mexico, New York, North Carolina, Oregon, Pennsylvania, Vermont, and Washington have also opposed the repealing of the rule.
