In welcome news, the U.S. Court of Appeals for the District of Columbia Circuit ruled that the Environmental Protection Agency exceeded its authority by lifting summertime restrictions on the sale of a 15 percent ethanol fuel blend known as E15. The MIC, the Specialty Vehicle Institute of America and the Recreational Off-Highway Vehicle Association (ROHVA) oppose further expansion of E15 in the marketplace as this fuel significantly harms engines in a wide range of products and results in performance degradation, emission increases, fuel leaks, engine failures, and voids manufacturer warranties.
The court ruled that Clean Air Act provisions prohibit the sale of certain fuels with higher volatility from June 1 through September 15 to limit smog. In 2019, the EPA extended a waiver that allowed year-round sales of E15, expanding sales of the blend. E15 is not approved for use in motorcycle, ATV, and side-by-side engines, small engines, and lawnmowers and its use in these applications is illegal.
