Maintenance Plan Revision for the St. Louis (Missouri) Maintenance Area Under the 1979, 1997, and 2008 Ozone Standards

This plan revision replaces the currently approved maintenance plan for the Missouri portion of the St. Louis maintenance area under the 2008 ozone standard. This standard is more stringent than the 1979 and 1997 ozone standards; therefore this revision also replaces the previous maintenance plans under those standards.  The revision updates the maintenance demonstration showing that continued implementation of Missouri’s vehicle inspection and maintenance program and federal reformulated gasoline requirements in the area are not necessary for the area to continue to maintain compliance with the 2008 ozone standard.

Inspection and Maintenance Program for the St. Louis Area – 2019 Revision

This State Implementation Plan (SIP) revision updates Missouri’s on-road motor vehicle emissions inspection and maintenance (I/M) program in the St. Louis area, also known as the Gateway Vehicle Inspection Program. The revision requests EPA approval to fully remove the I/M program requirements in Franklin and Jefferson counties from Missouri’s SIP. The revision does not remove the I/M program requirements in the City of St. Louis or the counties of St. Louis or St. Charles. The Missouri Department of Natural Resources’ Air Pollution Control Program is evaluating the continued need for the program in these remaining counties with respect to the 2015 ozone standard, for which these counties are currently designated nonattainment. The revision also includes several updates to reflect current operations of the program.
