## Abstract

The Environmental Protection Agency (EPA) is taking direct final action to approve the State Implementation Plan (SIP) revision submitted by the state of Missouri on January 14, 2014, for the purpose of removing an outdated rule. This action amends the SIP to remove a rule that was originally approved in 1972 but has now been rescinded. The rule's purpose was to control emissions from all vehicles subject to required vehicle safety inspections in areas outside of the Kansas City, Springfield, and St. Louis metropolitan areas. Vehicle manufacturers now produce newer technology in exhaust emissions equipment in order to meet more stringent Federal motor vehicle standards.
