"WASHINGTON - A federal appeals court on Wednesday temporarily blocked a decision by the U.S. Environmental Protection Agency that would have lifted strict limits on the number of remanufactured heavy duty vehicles known as “glider trucks” that could be sold.
The vehicles have a used engine in a new frame and rules introduced under former President Barack Obama, a Democrat, said nearly all new trucks on the road must use more efficient, less polluting engines.
The glider trucks emit up to 450 times more diesel particulate matter and up to 40 times more smog-forming nitrogen oxides than new trucks on the market, the EPA has said."
