## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Missouri State Implementation Plan (SIP) received by EPA on December 11, 2018. The submission revises Missouri's regulation relating to measurement of emissions of air contaminants which allows the director to obtain air contaminant emission data upon request. This final action will amend the SIP to include revisions which are administrative in nature and do not impact the stringency of the SIP. Specifically, these revisions reformat the regulations and add definitions. Approval of these revisions will not impact air quality, ensures consistency between the State and Federally-approved rules, and ensures Federal enforceability of the State's rules.
