EPA and other government agencies would be barred from requiring emissions controls on motor vehicles and wouldn’t be able to punish people who’ve tampered with exhaust systems, under a bill by Sen. Cynthia Lummis.
Lummis, a Wyoming Republican, filed S. 3007, the “Diesel Truck Liberation Act of 2025,” after one of her constituents was sentenced to prison for violations of the Clean Air Act in a case involving diesel truck exhaust systems.
Lummis has asked President Donald Trump to pardon the business owner, Troy Lake, and said the bill was another step toward correcting what she called an injustice.
“I want this overreach to end. Democrats weaponized the EPA to wage war on rural America, and we cannot let that happen again,” Lummis said in a statement. “This legislation is the first step toward justice and sanity.”
