Nonroad Engines, Equipment, and Vehicles

Snowmobiles, Dirt Bikes, and ATVs

April 3, 2013: EPA withdrew its approval of the import and sale of over 70,000 gas-powered on- and off-road motorcycles and all-terrain vehicles because the agency believes that it received either incomplete or falsified certification information. EPA issued the vehicle certificates from 2006 to 2012 to two companies which operate as Snyder Technology, Inc. and Snyder Computer Systems, Inc. (doing business as Wildfire Motors Corporation). As a result of a lengthy investigation, the agency believes that the applications for the certificates contained fallacious information and must be voided. All vehicles imported into or manufactured in the United States are required to have certificates of conformity. For more information please see the press release.
