The Environmental Protection Agency (EPA) published a notice in the Federal Register requesting comments regarding a proposed consent decree related to Sierra Club v. Pruitt, which calls for a study to determine whether renewable fuel volumes–including more ethanol in the fuel supply–will adversely impact air quality as a result of changes in vehicle and engine emissions of air pollutants required by the program (Anti-backsliding Study). The National Marine Manufacturers Association (NMMA) will file comments that based on previous studies it is aware that higher volumes of ethanol in the fuel supply will lead to worse air quality.

The comment period is open until Monday, March 25, 2019. To access the Federal Register page and submit a comment, visit here.
