DETROIT (AP) — The Biden administration is proposing stronger pollution regulations for new tractor-trailer rigs that would clean up smoky diesel engines and encourage new technologies during the next two decades. The proposal released Monday by the Environmental Protection Agency would require the industry to cut smog-and-soot-forming nitrogen oxide emissions by up to 90% per truck over current standards by 2031. Although truck manufacturers are working on battery-electric and hydrogen fuel cell powertrains, the EPA says the proposal is not a zero-emissions truck requirement. Rather, the agency says there are pollution control devices in development that can keep diesels in use and still clean the air.
