About this enforcement action
Settlement for alleged Clean Air Act violations involving emissions tampering on vehicles in the operator's fleet.
Regulatory context — Fleet operator cases
Fleet operator cases involve businesses that own or operate motor vehicles and that have allegedly tampered with the emissions control systems on vehicles in their fleet. Section 203 of the Clean Air Act, 42 U.S.C. § 7522, prohibits any person — including a vehicle owner or operator — from removing or rendering inoperative any emission control device installed by the manufacturer to comply with EPA emission standards. Fleet cases typically allege EGR removal, DPF removal, or DEF system disabling on commercial vehicles.
