The Clean Air Act prohibits any vehicle or engine from being imported and sold in the United States unless it is covered by a valid, EPA-issued certificate of conformity indicating that the vehicle or engine meets applicable federal emission standards. The certificate of conformity is the primary way EPA ensures that imported vehicles and engines meet emission standards. This settlement is part of an ongoing effort by EPA to ensure that all imported vehicles and engines comply with the Clean Air Act’s requirements.
