## Abstract

EPA is announcing it is approving a revision to the Missouri State Implementation Plan (SIP). This revision pertains to two Missouri rules, applicable to the Springfield-Greene County area and out-state area, which control particulate matter emissions from fuel burning equipment used for indirect heating. The effect of this approval is to ensure Federal enforceability of the state air program rules and to maintain consistency between the state-adopted rules and the approved SIP.
