## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Missouri State Implementation Plan (SIP) which were submitted to EPA on July 12, 2012. This submission revises two heavy duty diesel vehicle idling rules that are applicable in Kansas City and St. Louis. This revision provides clarity to the rules in the applicability section by listing owners and operators of passenger load/unload locations where commercial, public and institutional heavy-duty vehicles load or unload passengers. The affected parties were unintentionally omitted from the applicability section of the rule even though they are required to comply with the rule in the general provisions section. These revisions do not have an adverse affect on air quality. EPA's approval of these SIP revisions is being done in accordance with the requirements of the Clean Air Act (CAA).
