The Waite Park mail processing facility is on the Postal Service's list for possible closing.

More than 250 offices across the country are part of the proposal.

There are three other offices under consideration in Minnesota are: Bemidji, Duluth, and Rochester.

Changes in delivery standards such as no Saturday service and slower delivery could save the agency as much as $3 billion, and officials are seeking changes from Congress that could help them cut expenses more.

The Postal Service lost $8.5 billion last year and is facing an even larger deficit this year as it struggles to compete with the Internet as a lot of people switch to paperless billing and online bill pay, eliminating the number of envelopes they send out to mail checks. The struggling economy is also being blamed due to the lack of advertising mail.

The mail that the Waite Park facility handles would instead be distributed by their larger processing center in Minneapolis. The Postal Service has reiterated that as of right now, this is just a proposal.
