On January 23, 2017, the Michigan Department of Environmental Quality (MDEQ) published for public comment The State of Michigan's Analysis of Interstate Transport of Fine Particulate Matter for the 2012 PM2.5 NAAQS (PM2.5 Transport SIP). The PM2.5 Transport SIP is required to address the impact of emissions generated in the state of Michigan on the ability of other states' to achieve attainment with the 2012 PM2.5 National Ambient Air Quality Standard (NAAQS). In its proposed State Implementation Plan (SIP), Michigan concludes in-state emissions do not impact potential nonattainment in Idaho or California. Michigan further concludes that existing in-state emission reduction trends and prevailing wind directions show that Michigan's emissions will not hinder attainment with the 2012 PM2.5 NAAQS in Pennsylvania. Comments on the PM2.5 Transport SIP are being accepted by MDEQ until February 22, 2017. A copy of the PM2.5 Transport SIP can be found on MDEQ's website.
