EPA approves additional RFS fuel pathways
The U.S. EPA has issued a supplemental final rule under the renewable fuel standard (RFS) pertaining to biofuels made from giant reed and napier grass feedstock. The rule contains a life-cycle greenhouse gas (GHG) analysis of biofuels made from these feedstocks, along with a final regulatory determination that such fuels meet the 60 percent GHG reduction threshold needed to qualify as cellulosic under the renewable fuel standard (RFS).
The rule also establishes a system of registration, recordkeeping and reporting requirements designed to address concerns over the invasive potential of the species. Biofuel producers utilizing the feedstocks are required to demonstrate the growth of giant reed or napier grass will not post a significant likelihood of spreading beyond the planted area, or that the invasive risks are being managed and minimized through an EPA-approved risk management plan that includes means for early detection and rapid response to potential spread, among other provisions.
