Which statement is incorrect about the explanations for the processes regarding either the approval or declining of governors' requests for major disaster or emergency declarations?

In the $1980$s$,$ FEMA suggested "objective criteria" by which to approve or deny governor requests for presidential declarations of major disasters or emergencies.

According to the FEMA's "objective criteria," the president is obliged by law to follow the suggested criteria when deciding the declarations. So$,$ there is no place of the president's discretion.

The president is free to disregard the FEMA criteria and judge governor requests case by case.

Only governors of states can ask for major disaster and emergency declarations.
