Regulation of Fuels and Fuel Additives: Removal of the Reformulated Gasoline Program From the Northern Kentucky Portion of the Cincinnati-Hamilton Ozone Maintenance Area

In this final action, EPA is amending its reformulated gasoline regulations to reflect that Boone, Campbell, and Kenton counties in Kentucky (the Northern Kentucky Area), which are part of the Cincinnati-Hamilton, Ohio-Kentucky-Indiana ozone area, are no longer federal reformulated gasoline (RFG) covered areas as of July 1, 2018. As described in a separate document published on May 16, 2018, pursuant to EPA's regulations, EPA approved an April 18, 2017 petition from the state of Kentucky to opt-out of the federal RFG program and removed the requirement to sell federal RFG in the Northern Kentucky Area as of July 1, 2018. This effective date applies to retailers, wholesale purchaser-consumers, refiners, importers, and distributors. This rulemaking merely conforms the list of RFG covered areas in the regulations to reflect the effective date of the opt-out for the Northern Kentucky Area.
