Missouri State Implementation Plan Revision - Supplement/Revision to the Redesignation Demonstration and Maintenance Plan for the Missouri Portion of the St. Louis Nonattainment Area for the 1997 8-Hour Ground Level Ozone National Ambient Air Quality Standard

The Missouri Department of Natural Resources’ Air Pollution Control Program (Air Program) is in the process of redesignating the St. Louis area to attainment for the 1997 ozone NAAQS. On Nov. 27, 2011, the Missouri Air Conservation Commission adopted the Redesignation Demonstration and Maintenance Plan for the Missouri Portion of the St. Louis Nonattainment Area for the 1997 Ozone NAAQS. The plan was then submitted to the U.S. Environmental Protection Agency (EPA) on Nov. 28, 2011, for inclusion in the Missouri State Implementation Plan.  The plan was not acted upon at that time due to litigation surrounding the federal interstate air pollution transport rules. The Air Program is now proposing a technical supplement/revision to the 2011 plan. This revision will make corrections to the emissions inventories in the plan and update the future year projections of the plan from 2022 to 2025.
