Technical Correction to the Redesignation Request and Maintenance Plan for the St. Louis (Missouri) 2008 Ozone Standard Nonattainment Area

This technical correction addresses the St. Louis nonattainment area Redesignation Request and Maintenance Plan under the 2008 ozone standard. The plan was submitted to the U. S. Environmental Protection Agency on September 12, 2016, including a maintenance plan to demonstrate the area will continue to meet the standard in future years as outlined in emission inventory projections, contingency measures, and motor vehicle budgets. Technical corrections to the emissions inventory and motor vehicle budgets fix an error in the mobile emission estimates. The correction does not affect the maintenance of air quality in the five-county St. Louis region in the future year. Redesignation to attainment will occur when the U. S. Environmental Protection Agency gives final approval to the plan, including the technical correction.

Revision to Area Boundary Designation Recommendation for the 2015 Ozone Standard

Missouri is proposing to submit to the U.S. Environmental Protection Agency a revised boundary designation recommendation for the 2015 ozone standard. This revised recommendation replaces the recommendation submitted to the EPA on September 30, 2016. Nonattainment recommendations are for areas with monitored violations based on 2015-2017 preliminary monitoring data and areas contributing to the violation. All other areas of the state are recommended for an unclassifiable/attainment designation. The air program intends to submit this revised recommendation to EPA to consider prior to finalizing the designations for the 2015 ozone standard. This action will not be submitted for inclusion in the Missouri State Implementation Plan.
