## Abstract

The EPA is taking final action to approve certain portions of new Missouri rule 10 CSR 10-6.020 as a revision to the State Implementation Plan (SIP). This rule consolidates the SO<INF>2</INF> requirements previously contained in eight separate rules into one statewide rule. The EPA is taking final action to rescind eight rules which are replaced by the new rule, and the EPA is taking final action to approve Missouri's Clean Air Act (CAA) section 111(d) plan for sulfuric acid mist plants which is now contained in the new rule.
