Approval and Promulgation of Implementation Plans; State of Missouri

The Environmental Protection Agency (EPA) is announcing a revision to the State Implementation Plan (SIP) which incorporates new Missouri rule 10 CSR 10-6.330 entitled ``Restriction of Emissions from Batch-Type Charcoal Kilns.'' Missouri's rule requires a substantial reduction of emissions of volatile organic compounds (VOC) (some of which are toxic), particulate matter (PM<INF>10</INF>), and carbon monoxide (CO) from charcoal-producing ovens commonly called charcoal kilns. The implementation of this rule will result in a significant improvement in air quality, especially in central and southern Missouri where most of these facilities are located.
