Chapter 119: Motor Vehicle Fuel Volatility Requirements

Ch119 draft final rule :: Ch 119 rule fact sheet :: Comment on this Rule

Concise Summary:

The 129th Maine Legislature repealed the requirement to sell only reformulated gasoline (RFG) in certain counties in Southern Maine as of November 1, 2020. After petitioning U.S. EPA and submitting a State Implementation Plan revision, EPA approved Maine's petition and determined that the removal of the federal RFG program for the Southern Maine Area is consistent with the applicable provisions of the Clean Air Act and EPA's regulations. This Amendment will remove from Chapter 119 the RFG requirement, which is no longer required in the Southern Maine Area due to EPAs approval.
