WASHINGTON – The U.S. Environmental Protection Agency (EPA) announced a settlement with recreational vehicle manufacturers, Loncin (USA), Inc., Longting USA LLC, and Chongqing Longting Power Equipment Co., Ltd., to resolve violations of the Clean Air Act (CAA) related to the importation of 7,115 uncertified recreational vehicles into the United States. Engines that are not certified may be operating without proper emissions controls, which can emit excess carbon monoxide and nitrogen oxides and cause respiratory illnesses, aggravate asthma and contribute to the formation of ground level ozone, or smog. “EPA is committed to enforcing vehicle emission standards under the Clean Air Act,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. “By taking action to deter the importation and sale of non-compliant engines, EPA is ensuring a level playing field for manufacturers and protecting Americans from illegal air emissions.”
