The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Maryland. This SIP revision removes requirements for gasoline vapor recovery equipment (also known as Stage II vapor recovery) on fuel dispensers at both new and upgrading gasoline dispensing facilities (GDFs) in Stage II subject areas of Maryland and also allows for decommissioning of Stage II equipment at existing stations currently equipped with Stage II equipment. GDF owners may elect to retain existing Stage II equipment, but in doing so remain subject to Stage II requirements and must continue to test and maintain Stage II equipment in accordance with program requirements. EPA determined that Maryland's August 25, 2017 SIP revision is approvable in accordance with the requirements of the Clean Air Act (CAA).
