(a) Notice and purchase of coverage. If a national bank or Federal savings association, or a servicer acting on behalf of the bank or savings association, determines at any time during the term of a designated loan, that the building or mobile home and any personal property securing the designated loan is not covered by flood insurance or is covered by flood insurance in an amount less than the amount required under § 22.3, then the national bank or Federal savings association, or a servicer acting on its behalf, shall notify the borrower that the borrower should obtain flood insurance, at the borrower's expense, in an amount at least equal to the amount required under § 22.3, for the remaining term of the loan. If the borrower fails to obtain flood insurance within 45 days after notification, then the national bank or Federal savings association, or its servicer, shall purchase insurance on the borrower's behalf. The national bank or Federal savings association, or its servicer, may charge the borrower for the cost of premiums and fees incurred in purchasing the insurance, including premiums or fees incurred for coverage beginning on the date on which flood insurance coverage lapsed or did not provide a sufficient coverage amount.

(b) Termination of force-placed insurance—(1) Termination and refund. Within 30 days of receipt by a national bank or Federal savings association, or by a servicer acting on its behalf, of a confirmation of a borrower's existing flood insurance coverage, the national bank or Federal savings association, or its servicer, shall:

(i) Notify the insurance provider to terminate any insurance purchased by the national bank or Federal savings association, or its servicer, under paragraph (a) of this section; and

(ii) Refund to the borrower all premiums paid by the borrower for any insurance purchased by the national bank or Federal savings association, or by its servicer, under paragraph (a) of this section during any period during which the borrower's flood insurance coverage and the insurance coverage purchased by the national bank or Federal savings association, or its servicer, were each in effect, and any related fees charged to the borrower with respect to the insurance purchased by the national bank or Federal savings association, or its servicer, during such period.

(2) Sufficiency of demonstration. For purposes of confirming a borrower's existing flood insurance coverage under paragraph (b) of this section, a national bank or Federal savings association, or a servicer acting on its behalf, shall accept from the borrower an insurance policy declarations page that includes the existing flood insurance policy number and the identity of, and contact information for, the insurance company or agent.
