Chico Calif.-- The Environmental Protection Agency is calling for a reduction of greenhouse gas emissions standards for new vehicles starting in 2022.
The agency says that the standard put in place by the Obama administration in 2012 needs to be revised.
Trucks and SUV's are becoming far more popular these days that smaller vehicles and that's because of a drop in il prices.
Which also contributed to the EPA's emissions roll-back.
EPA administrator Scott Pruitt says they'll will work with all states, including california, to finalize new standards.
President Trump says this will save automakers the expense of building two versions of cars and trucks: one for states like california and another for the rest of the country.
Congressman Doug LaMalfa says this could be a great thing for the economy and the american people.
"The standard was going to be that every car in the american fleet would have to average 54.5 miles per gallon in only 7more model years .... government can't just cram these mandates on people and expect it to work every time, this is going to limit the choices of people for vehicles that fit their life, their family, their work place, and what they need," said LaMalfa.
But right now, California still has a waiver that allows it to impose stricter emissions rules.
California's Attorney General Xavier Baccera said "We're ready to file suit if needed to protect these critical standards and to fight the administration's war on our environment."
If standards were to be eased in California this could have an adverse impact on air quality in the north state.
"The state of California does experience the worst pollution problems in the country," said Jason Mandly, planner for the Butte County Air Quality Management District. "In part because of the population as well as the topography; there are air sheds with very little air movement and large populations centers, so the challenges in California are different."
While the fate of California's right to a waiver is undetermined, for the rest of the country, the EPA will now work with the national Highway Traffic Safety administration to develop new standards.
They'll then have to be proposed and subjected to public comment before final approval.
