The Administrator shall carry out a program, to be known as the Immediate Disaster Assistance program, under which the Administration participates on a deferred (guaranteed) basis in 85 percent of the balance of the financing outstanding at the time of disbursement of the loan if such balance is less than or equal to $25,000 for businesses affected by a disaster.

To receive a loan guaranteed under subsection (a), the applicant shall also apply for, and meet basic eligibility standards for, a loan under subsection (b) or (c) of section 636 of this title.

A person who receives a loan under subsection (b) or (c) of section 636 of this title shall use the proceeds of that loan to repay all loans guaranteed under subsection (a), if any, before using the proceeds for any other purpose.

The Administrator shall ensure that each applicant for a loan under the program receives a decision approving or disapproving of the application within 36 hours after the Administration receives the application.
