The Secretary may require persons for whom the services are performed to reimburse the Secretary for any sums of money paid by the Secretary for the services. All funds collected under this paragraph shall be credited to the account that incurs the costs and shall remain available until expended without fiscal year limitation. Upon failure to reimburse the Secretary in accordance with this section, the Secretary may assess a late payment penalty, and the overdue funds shall accrue interest, as required by section 3717 of title 31 . Any late payment penalty and any accrued interest shall be credited to the account that incurs the costs and shall remain available until expended without fiscal year limitation.
