Air Plan Approval; Michigan; Sewage Sludge Incinerators State Plan and Small Municipal Waste Combustors Negative Declaration for Designated Facilities and Pollutants

The Environmental Protection Agency (EPA) is approving Michigan's State Plan to control air pollutants from ``Sewage Sludge Incinerators'' (SSI). The Michigan Department of Environmental Quality (MDEQ) submitted the State Plan on September 21, 2015. The State Plan is consistent with the Emission Guidelines (EGs) promulgated by EPA on March 21, 2011. This approval means that EPA finds that the State Plan meets applicable Clean Air Act (Act) requirements for subject SSI units. Once effective, this approval also makes the State Plan Federally enforceable. EPA is also notifying the public that we have received from Michigan a negative declaration for Small Municipal Waste Combustors (SMWC). The MDEQ submitted its negative declaration on July 27, 2015. MDEQ notified EPA in its negative declaration letter that there are no SMWC units subject to the requirements of the Act currently operating in Michigan.
