The Mining Journal ( http://bit.ly/17Fswbc) says Daley will give the keynote address at the 10th annual conference of the Great Lakes and St. Lawrence Cities Initiative. The nonprofit coalition focuses on protecting and restoring the water system.
The conference runs June 19-21 in the Upper Peninsula city. Daley's speech is June 20.
Organizers say about 100 municipalities in eight states and two Canadian provinces are represented in the coalition. They say Daley was one of its founders.
The 70-year-old Daley was Chicago's mayor from 1989 to 2011, when Rahm Emanuel succeeded him.
