WASHINGTON, D.C. – Yesterday, the U.S. Environmental Protection Agency (EPA) released its updated guidance on what methods should be used to determine the cellulosic converted fraction of corn kernel fiber in the production of cellulosic ethanol. Growth Energy CEO Emily Skor released the following statement in response:

“We’re pleased to see EPA update its guidance for cellulosic biofuel from kernel fiber, a move that provides additional flexibility for bioethanol producers and the potential to accelerate stalled registrations for cellulosic biofuels. Approval of these registrations is important to fulfilling the goals of the Renewable Fuel Standard and to help further decarbonize the transportation sector. We look forward to further reviewing EPA’s guidance with our members.”

In its guidance, EPA proposes three potential ways companies might satisfy registration requirements for corn fiber, including:

  • Adoption of the DOE/NREL method,
  • Demonstration of reasonable accuracy by returning comparable cellulose values to the NIST reference materials using a non-voluntary consensus standards body (non-VCSB) method, or
  • Use of advanced analytical techniques; e.g. mass spectrometry (MS) and nuclear magnetic resonance spectroscopy (NMR), as identified by DOE/NREL in their analytical method and validation.

We applaud @EPA's forward-looking RFS Set for including: ✅ Implied conventional volumes above 15BG for each of the next 3 years ✅ Restored 250 million gallons of biofuel demand from 2016 ✅ Highest ever percentage standards for total renewable fuel bit.ly/3VtsyCz

New 🚨 @EPA released its Set rulemaking, ushering in a new era of the RFS and growing ethanol's role in decarbonizing transportation now and into the future. We’re grateful to @POTUS + @EPAMichaelRegan for keeping clean energy on an upward trajectory. growthenergy.org/2022/12/01/gro… https://t.co/pAObZELyGk

Nearly 70% of U.S. ethanol production is moved by rail. No one wants to see American motorists cut off from a vital supply of lower-cost, lower-carbon fuels so we urge both chambers to quickly to adopt this legislation. twitter.com/ChrisClaytonDT…
