West Virginia leads push for EPA to delay Tier 4 emission standards 

McCuskey says the Biden administration had proposed standards that could only have been met by broadly electrifying Americans’ vehicle fleet. Beyond moving compliance dates, the present EPA has said it will also revisit whether the Biden EPA standards should remain at all in later rulemaking, and the coalition agrees the standards should be repealed.

The coalition’s letter explains why regulatory and factual circumstances have changed in ways that justify at least delaying the implementation of the new standards. The states describe how the market has not moved toward electrification as expected, with some automakers reducing electric vehicle (EV) production.

Besides lower than expected consumer demand, the states contend that the electric grid cannot handle the increased demand, increasing prices and reliability challenges that would come from electrifying the vehicle fleet.

“The standards are so strict that auto makers would have no choice but to build many more electric vehicles,” McCuskey said. “This may not be an official EV mandate, but in reality, it functions like one.

“Add to that, EV batteries require minerals that come from China and the Democratic Republic of the Congo – how soon would consumers have to worry about supply issues, not to mention the question of national security. I’m pleased the present administration is fixing the terrible mistakes of the last one.”

In addition, the coalition claims the EPA lacks the legal authority to force a transition from gasoline vehicles to EVs at all. The states argue that Tier 4 exceeds what Congress authorized the EPA to do. Further, they contend Tier 3 regulations already have improved air quality.

“The Tier 3 standards have already reduced criteria pollutant emissions by 99%,” the AGs wrote in the letter dated July 6. “EPA shouldn’t impose another round of costly, illegal regulations to squeeze a fraction out of the last percent, especially before the nation’s fleet has a chance to catch up.

“EPA should give automakers and consumers breathing room by delaying implementation.”

Attorneys general from Alabama, Alaska, Arkansas, Florida, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Missouri, Montana, Nebraska, North Dakota, Ohio, Oklahoma, South Carolina, South Dakota, Tennessee, Texas and Wyoming joined the West Virginia-led letter.
