Comments to EPA on Grandfathering and Glider Trucks

The Environmental Protection Agency (EPA) has proposed to grandfather glider trucks, which have new truck bodies but old powertrains, into older emissions requirements. Our comments to EPA argue that the Agency improperly disregarded the effects that this exemption would have on air pollution, public health, and environmental quality, in violation of both the Clean Air Act and applicable executive orders on cost-benefit analysis. In particular, EPA failed to consider the extent to which its action will increase air pollution (and attendant environmental harms) by extending the useful economic life of older, dirtier powertrains.
