The House Oversight and Government Reform Subcommittee on Energy Policy, Health Care, and Entitlements held a hearing June 5 to examine the anticipated “blend wall” as part of the RFS. Environmental Protection Agency Office of Transportation and Air Quality Director Christopher Grundler said the agency is considering public comments on standards to manage the blend wall, and these standards will be released sometime this summer. Representative Jim Jordan (R-OH) advocated that the agency create a strong definition of harm when reaching a decision.
