## Abstract

EPA is taking direct final action to approve a revision to the Missouri State Implementation Plan (SIP) to incorporate a new Missouri regulation to restrict Particulate Matter (PM) emissions from fuel burning equipment used for indirect heating. The new regulation consolidates four existing area-specific regulations into one state- wide rule for clarity. The requirements prescribed in the new regulation are as stringent as the conditions specified in the currently approved SIP with the four existing area-specific regulations. EPA has determined that the SIP revision submitted by the State of Missouri satisfies the applicable requirements of the Clean Air Act (CAA or Act).
