Approval and Promulgation of Air Quality Implementation Plans; Indiana; Stage I Vapor Recovery Rule

EPA is approving into the Indiana State Implementation Plan (SIP), amendments to the stage I vapor recovery rule and administrative changes to stage II vapor recovery rule submitted by the Indiana Department of Environmental Management on June 11, 2010. These rule revisions made volatile organic compounds (VOC) emission control requirements for filling at gasoline dispensing facilities more stringent by applying them statewide, making the rule applicable to smaller tanks and revising the requirements for newer submerged fill pipes. These new State requirements update the SIP consistent with new Federal requirements from January 10, 2008 area source National Emissions Standards for Hazardous Air Pollutants (NESHAPs) for gasoline dispensing facilities. The revisions also delete references to compliance dates which have passed. The rules are approvable because they are consistent with the Clean Air Act (Act) and EPA regulations, and should result in additional emission reductions of VOCs throughout Indiana.
