EPA, following California, moves to tighten heavy truck emission regs

The Biden administration is moving to lessen emissions from heavy trucks and buses in the first federal effort to eliminate smog and pollution from those vehicles since 2001. The Environmental Protection Agency (EPA) is drawing up rules that would remove smog-forming nitrate oxide (NOx) emissions by up to 90% by 2031. The new rule would cover buses, light-duty delivery vans, tractor-trailers and other heavy trucks.
