Explanation:

The phrase "the Great Lakes State" is a nonrestrictive appositive. It provides extra, non-essential information about Michigan (Michigan is already a specific state, so this phrase just adds descriptive detail, not necessary identification). Nonrestrictive appositives require commas to set them off from the noun they describe.

Answer:

Michigan, the Great Lakes State, has the world's largest freshwater coastline; it's more than three thousand miles long.
