Redesignation Request for the Labadie Unclassifiable Area Under the 2010 Sulfur Dioxide Standard

This action requests the U.S. Environmental Protection Agency (EPA) to redesignate the Labadie unclassifiable area to attainment under the 2010 sulfur dioxide (SO2) standard.  The Labadie area includes portions of Franklin and St. Charles counties, and EPA designated the area unclassifiable under the 2010 SO2 standard on July 12, 2016. Certified ambient monitoring data for 2017-2019 shows the area is in compliance with the standard, which supports a redesignation to attainment. This request is in accordance with Section 107(d)(3)(D) of the Clean Air Act. Redesignation to attainment will occur when EPA promulgates final approval of this request.

Missouri State Implementation Plan Revision – Plan for Continued Attainment of the 2008 Lead Standard in Liberty and Arcadia Townships in Iron County, Doe Run Glover Facility

This plan replaces a 2003 maintenance plan and settlement agreement for Liberty and Arcadia townships, which surround an historic primary lead smelter in Glover, Missouri. The 2003 plan was designed to ensure the area maintained compliance with the 1978 lead standard. The smelter was idled in 2003, and the owner has removed a majority of the lead process-related equipment at the facility. This plan includes a new consent agreement that updates the requirements to reflect the current status of the facility. The new plan is designed to maintain compliance with the more stringent 2008 lead standard in the area going forward.
