## Abstract

On May 19, 2017, the State of Alabama, through the Alabama Department of Environmental Management (ADEM), submitted changes to the Alabama State Implementation Plan (SIP). The Environmental Protection Agency (EPA) is taking direct final action to approve the submission. Specifically, the revision pertains to definitional changes, including the modification of the definition of "volatile organic compounds" (VOCs), correction of a typographical error, and removal of control of particulate emissions and opacity limits. EPA is taking direct final action to approve the SIP revision because the State has demonstrated that these changes are consistent with the Clean Air Act (CAA or Act).
