Trucking and construction industry groups filed a lawsuit Friday challenging U.S. EPA’s approval of a waiver that allows California to enforce stronger-than-federal emissions standards for diesel trucks.
The move is the latest hurdle for the state’s nation-leading clean air standards, which congressional Republicans already plan to revoke through a regulatory maneuver.
What happened: The conservative Pacific Legal Foundation filed the complaint in the 9th U.S. Circuit Court of Appeals, arguing that the Biden administration’s December decision to approve California’s Heavy-Duty Low NOx waiver should be declared illegal.
The complaint, filed on behalf of groups including the Western States Trucking Association and New York Construction Materials Association, does not include details about the potential harm businesses face because of the waiver approval, stating simply that the petitioners have been “adversely affected.”
