This week, the postal service said in a document that it would turn the Milan facility into a “local processing center.” It will only process certain kinds of mail, and the rest, including outgoing mail, will go to a processing and distribution center in Des Moines.
It's part of a $40-billion plan to make the national postal network cheaper and more efficient.
The changes also include around $6-million in facility improvements. The postal service says the changes do not include any "career employee layoffs."
Last month, Senator Dick Durbin and Senator Tammy Duckworth, along with several state representatives, including Congressman Eric Sorensen, wrote a letter to the postmaster general asking him to reconsider.
State Representative Dan Swanson also released a statement Thursday saying he was disappointed with the decision.
