The U.S. Environmental Protection Agency (EPA) is expected to grant California a waiver to phase out sales of diesel trucks, according to the Washington Post.

The EPA will likely grant California a waiver to implement the waiver and other regulations in the coming weeks, according to the report.

The regulations feature a requirement for automakers to sell an increasing number of electric trucks, as the state aims to fade out 100% of diesel trucks by 2045. Companies looking to move away from diesel can also sell hydrogen-powered vehicles.

Another regulation California is expected to move forward with would further limit the emission of nitrous oxides and particulate from diesel vehicles. California would require truckmakers to put these changes in place for the 2024 model year instead of the 2027 model year required by the federal government, according to the report.

California would also require companies to ensure their new emission controls continue to work throughout the vehicle’s lifetime.

New York, New Jersey, Vermont, Oregon, Washington state, and Massachusetts are expected to implement these regulations.

U.S. Rep. John Joyce (R-PA) introduced the “Preserving Choice in Vehicle Purchases Act,” which was a response to California’s plans to ban the sale of new gas- and diesel-powered cars and trucks in 2035 unless certain conditions are met.

If approved, the bill would prevent the EPA from allowing California’s Zero Emissions Vehicle regulations.
