Rationale

CONCURRENT D02 AND D02.A BALLOT TO UPDATE ASTM D4814-25a “STANDARD SPECIFICATION FOR AUTOMOTIVE SPARK-IGNITION ENGINE FUEL” TO REMOVE KENTUCKY RFG AREAS FROM TABLE 6, “U.S. FEDERAL RFG AREAS REQUIRING VOLATILITY CLASS AAA” TO ALIGN WITH EPA FINAL RULE BACKGROUND This ballot proposes to align ASTM D4814-25a “Standard Specification for Automotive Spark-Ignition Engine Fuel” with EPA’s action removing the Kentucky portion of the Louisville, RFG Area from EPA’s list of RFG covered areas. On March 2, 2026, the Environmental Protection Agency published a notice of final action in the Federal Register approving the petition by the Commonwealth of Kentucky to opt-out of the reformulated gasoline program and remove the requirement to sell RFG in Jefferson County and parts of Bullitt and Oldham Counties (the “Kentucky portion of the Louisville Area”). The effective date for removal of the Kentucky portion of the Louisville Area from the RFG program was May 27, 2026, but under EPA’s National Fuel Waiver, the opt-out will be effective May 1, 2026. As stated in EPA’s Federal Register Notice published March 2, 2026: "The U.S. Environmental Protection Agency (EPA) is announcing the approval of the petition by the Commonwealth of Kentucky ( “Kentucky” or “the Commonwealth”) to opt out of the reformulated gasoline (RFG) program and remove the requirement to sell RFG in Jefferson County and parts of Bullitt and Oldham Counties (the “Kentucky portion of the Louisville Area”), which are part of the Louisville Moderate nonattainment area for the 2015 ozone National Ambient Air Quality Standard (NAAQS) and the maintenance area for the 1997 ozone NAAQS. Specifically, by letter dated February 26, 2026, to the Governor of Kentucky, the EPA has approved the Commonwealth’s petition and set an effective date for the opt-out from the RFG program as May 27, 2026. The EPA has determined that this removal of the RFG program for the Kentucky portion of the Louisville Area is consistent with the applicable provisions of the Clean Air Act (CAA) and the EPA’s regulations."
