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.The new federal regulations are drawn from truck pollution rules recently enacted by California. These developments are a revival of California's influence on the nation's climate and clean air policies.This follows four years in which ex-President Donald Trump seemed at war with the Golden State. The Trump administration had stripped away California's authority to institute its own vehicle pollution standards, power that the state had enjoyed for more than 40 years. |
