## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP), the Operating Permit Program (OPP), and the 112(l) plan submitted on March 7, 2019, by the State of Missouri. The submission revises Missouri's regulations relating to the requirement for sources of air contaminants to obtain operating permits and to establish procedures for sources of air contaminants to obtain and comply with operating permits. These revisions are primarily administrative in nature and do not impact the stringency of the SIP, the OPP, or the 112(l) plan. Specifically, the revisions correct references, change the term "regulated pollutant" to "regulated air pollutant", removes unnecessary words, and add definitions. Approval of these revisions will not impact air quality and ensures Federal enforceability of the State's rules.
