Abstract
This final rule approves state implementation plan (SIP) revisions submitted by the State of California on June 15, 2004 and February 3, 2009, relating to reformulated gasoline (RFG) and diesel fuel sold or supplied as motor vehicle fuels in California. The revisions relating to RFG include California Phase 3 RFG (CaRFG3) regulations, correction of errors and streamlined requirements for compliance with and enforcement of the CaRFG3 standards, and an update to the State's predictive model to mitigate permeation emissions associated with the use of ethanol as a fuel additive. The revisions relating to diesel fuel include test methods for determining the aromatic hydrocarbon content in diesel fuel and reductions in the maximum allowable sulfur content for motor vehicle diesel fuel. The effect of today's action is to make these revisions federally enforceable as part of the California SIP.
