The U.S. ethanol industry is questioning a Environmental Protection Agency (EPA) “anti-backsliding” study released Friday on the air quality impacts of renewable fuels which also determined no further action is needed to mitigate any potential adverse impacts on air quality from the use of renewable fuels, reports

The Renewable Fuels Association (RFA) immediately raised concerns about EPA using a discredited modeling system called “MOVES” to make its determinations.

Before the agency began the study last year, RFA stressed the need for a new modeling methodology that incorporates real-world fuel inputs and scenarios.

In its March 2019 comments to the EPA, the RFA recommended the agency either replace the MOVES2014 model or make major modifications to it prior to embarking on the anti-backsliding study.
