On-road Vehicles and Engines


August 1, 2014: EPA withdrew its approval of the import and sale of over 28,000 gas-powered highway and off-road motorcycles and all-terrain vehicles because the agency believes that it received either incomplete or falsified certification information. All vehicles imported into or manufactured in the United States are required to have certificates of conformity. EPA issued the vehicle certificates from 2007 to 2011 to CFMoto. As a result of a lengthy investigation, the agency believes that the applications for the certificates contained fallacious information and must be voided. This notice follows actions in April 2013 and October 2013 in which EPA voided certificates from Snyder Computer Systems dba Wildfire Motors, American Lifan and Jonway which impacted up to 70,000; 61,000; and 39,000 vehicles, respectively. The applications were submitted by Michael Johnson of System Launch Associates who has pled guilty to wire fraud and submitting false statements under the Clean Air Act and is currently awaiting sentencing.
