## Abstract

EPA is announcing the redesignation of the lead nonattainment area in western Iron County, Missouri, to attainment of the National Ambient Air Quality Standards (NAAQS). We are approving the maintenance plan for this area including a consent order which was submitted with the redesignation request, and we are also approving the revision to Missouri's Restriction of Emissions of Lead From Specific Lead Smelter- Refinery Installations rule which ensures the permanent and enforceable emission reductions by clarifying the emissions limits for the Doe Run Resource Recycling Facility, and removes the text which could have allowed this facility to resume operation as a primary smelter.
