Summary

The Environmental Protection Agency (EPA) is proposing to approve a revision to the Minnesota sulfur dioxide (SO<INF>2</INF>) and particulate matter of less than 10 microns (PM<INF>10</INF>) State Implementation Plans (SIPs) as submitted on December 11, 2015. The revision will update the Rochester SO<INF>2</INF> and Olmsted County PM<INF>10</INF> maintenance plans to reflect changes in available controls, operating practices, and cleaner fuel options that have resulted in significant reductions of SO<INF>2</INF> and PM<INF>10</INF> emissions in the maintenance areas. EPA is also proposing to approve the removal of existing title I SO<INF>2</INF> SIP conditions for six facilities from the SO<INF>2</INF> SIP, and the state's evaluation that such changes ensure continued attainment of the SO<INF>2</INF> National Ambient Air Quality Standards (NAAQS).

The agency’s own summary, as published.
