Approval and Promulgation of Implementation Plans; State of Missouri; Restriction of Emission of Sulfur Compounds and Emissions Banking and Trading

摘要

EPA is proposing to approve two revisions to the State Implementation Plan (SIP) for Missouri that were submitted on September 5, 2012. The revision to the Missouri rule "Restriction of Emission of Sulfur Compounds" will remove redundant sulfur dioxide standards and outdated compliance dates. Due to these revisions, several within-rule references will be amended. Revisions to the Missouri rule "Emissions Banking and Trading" will remove all definitions, as they are now included in the general definitions rule. The reference to the state's Ambient Air Quality Standards rule that is included in the definition of National Ambient Air Quality Standards will also be removed. The revisions to Missouri's rules do not have an adverse affect on air quality. EPA's approval of this SIP revision is being done in accordance with the requirements of the Clean Air Act (CAA).
