## Abstract

Under the Clean Air Act, EPA is taking final action to approve certain revisions to the Arizona State Implementation Plan submitted by the Arizona Department of Environmental Quality. These revisions concern amendments to the statutory and regulatory provisions adopted by the State of Arizona to regulate volatile organic compound emissions from the transfer of gasoline from storage tanks to motor vehicle fuel tanks at gasoline dispensing sites, i.e., stage II vapor recovery. The revisions also amend the definition of "gasoline" to explicitly exclude E85 and thereby amend the requirements for fuels available for use in the Phoenix metropolitan area as well as the requirements for vapor recovery. In approving the revisions, EPA is taking final action to waive the statutory stage II vapor recovery requirements at E85 dispensing pumps within the Phoenix metropolitan area. Lastly, EPA is taking final action to correct an EPA rulemaking that approved a previous version of the Arizona rules regulating these sources and to thereby identify the appropriate regulatory agency and specific rules that were previously approved and incorporated by reference into the Arizona State Implementation Plan.
