## Abstract

The EPA is taking final action to approve revisions to Missouri's State Implementation Plan (SIP) concerning Missouri rules 10 CSR 10-2.260 and 10 CSR 10-5.220, ``Control of Petroleum Liquid Storage, Loading, and Transfer.'' The purpose of these revisions is to modify the required testing periods for petroleum delivery vessels in the Kansas City metropolitan area and in the St. Louis nonattainment area. These revisions are designed to reduce volatile organic compound emissions from the loading and unloading of gasoline delivery vessels during the ozone season. The reduction in emissions is part of the state's plan under the Clean Air Act (CAA) to reduce ozone levels in the St. Louis nonattainment area. This action will also ensure progress toward improved air quality in Kansas City.
