The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Maine. This revision incorporates Maine's statute repealing the State's requirement for the sale of federal reformulated gasoline (RFG) in York, Cumberland, Sagadahoc, Androscoggin, Kennebec, Knox and Lincoln Counties (hereinafter referred to as the ``southern Maine counties'') into the Maine SIP. The intended effect of this action is to approve the SIP revision and approve, but not incorporate into the SIP, the corresponding noninterference demonstration. At this time, EPA is not removing the requirement for the sale of federal RFG in the applicable southern Maine counties as that is the subject of a separate petition to the EPA Administrator submitted on August 20, 2020. The Administrator intends to act on that petition in the near future. This action is being taken in accordance with the Clean Air Act.
