                    On August 15, 2017, EPA proposed to approve certain changes to Michigan's minor new source review program which is contained in Part 2 of the Michigan Administrative Code. EPA had previously reopened the comment period due to an incomplete docket from November 2, 2017 to December 4, 2017. The file containing the state's September 2, 2003 submittal made available on                     *Regulations.gov*                     on September 12, 2017, was missing Attachment H which contained the state's technical analysis of the rule changes. The missing attachment was made available on                     *regulations.gov*                     on December 6, 2017, and EPA is reopening the comment period for an additional 15 days. The comment period now closes on January 24, 2018.                

Dated: December 20, 2017.

Robert Kaplan,

Acting Regional Administrator, Region 5.
