Northpine had a great synopsis of it so I'll just post it here (Its a upper midwest website so its geared towards this area
As part of its AM revitalization plan, the FCC has set its sights on 25 stations that had been expected to sign off years ago, including three in the Upper Midwest: KCFI/1250 (Cedar Falls-Waterloo), KZOT/1180 (Bellevue-Omaha), and WLMV/1480 (Madison).
The stations were among those granted permits to move to the expanded band (1620-1700) during the 1990's, with the plan that the old frequency would sign off after five years. Stations were chosen to move to the expanded band based on the amount of interference that would be reduced by their old frequency leaving the air. Stations in Des Moines, Iowa City, West Fargo, and Sussex-Milwaukee were among those which surrendered their old licenses as planned, but the 25 remaining stations never voluntarily signed off.
The notice of proposed rulemaking calls for a one-year deadline, to begin at a future date, for the 25 remaining licensees to surrender either their original frequency or their expanded band station. (The expanded band counterparts of the stations listed above are KDNZ/1650 Cedar Falls, KOZN/1620 Bellevue, and WOZN/1670 Madison.)
The FCC is also asking for comments on whether there is enough room in the expanded band to add more stations without creating too much interference, and who should be allowed to apply for new stations in the expanded band
