## Abstract

EPA is approving an update to the lead maintenance plan for Dakota County, Minnesota. This plan update demonstrates that Dakota County will maintain attainment of the lead National Ambient Air Quality Standard (NAAQS) through 2014. Minnesota has verified that the emission limits adopted to demonstrate modeled attainment continue to be met, that there are no new significant sources of lead or increases in background emissions, and that the state has in place a comprehensive program to identify sources of violations and address any violation through enforcement and implementation of a contingency plan.
