EPA proposes renewable fuel standard

The US Environmental Protection Agency released its expected Notice of Proposed Rulemaking (NPRM) detailing the implementation of changes to the existing Renewable Fuel Standard (RFS1) as required by the Energy Independence and Security Act of 2007 (EISA). The proposed rulemaking for RFS2 establishes new specific volume standards for cellulosic biofuel, biomass-based diesel, advanced biofuel, and total renewable fuel that must be used in transportation fuel each year.
