The Environmental Protection Agency has drafted a plan that would include a small bump in their biofuel-blending targets in 2021. 

Three people familiar with the matter told Bloomberg that the proposed rule is undergoing a White House review. 

Under the rule, the EPA would require refiners to use 5.17 billion gallons of advanced biofuels in 2021, up from 5.09 billion gallons this year. 

The plan would include 670 million gallons of cellulosic renewable fuels, such as those made from crop residue, switchgrass, and biogas harvested at landfills, up from the 590 million gallons required in 2020. 

Refiners would be able to use as much as 15 billion gallons of conventional renewable fuels, including corn-based ethanol, to satisfy the mandate in 2021. 

In 2022, the EPA draft plan would require refiners to use 2.76 billion gallons of biodiesel, typically made from soybeans and waste cooking oil. 

That requirement would be up from the 2.43 billion gallons required in 2021. 

The EPA is expected to propose the quotas in the coming months while facing a deadline of November 30 to finalize the targets.
