The US Environmental Protection Agency (EPA) is seeking public comment on any aspect of the use of isobutanol in gasoline. Butamax Advanced Biofuels, LLC, a manufacturer of isobutanol, has submitted an application pursuant to the regulations titled “Registration of Fuels and Fuel Additives” for the registration of isobutanol as a gasoline additive at up to 16% percent.

Butamax has submitted information that would likely satisfy the applicable registration requirements, EPA said. The Clean Air Act requires the EPA to register a fuel or fuel additive once all the applicable registration requirements have been met by the manufacturer.

Due to the potential for the widespread introduction of isobutanol into commerce, EPA said it was taking steps to make the public aware of the likelihood of this registration.

EPA is seeking public comment regarding any issues it should take into consideration for this registration and any supplemental actions we should consider under the Clean Air Act to further protect public health and welfare.

Comments must be received on or before 30 April 2018.
