108 STAT. 1266 PUBLIC LAW 103-272—JULY 5, 1994 (2) Paragraph (1) of this subsection applies to a project— (A) about which the sponsor notifies the Secretary, before the project begins, of the sponsor's intent to carry out the project; (B) that will comply with all statutory and administrative requirements that would apply to the project if it were carried out with amounts made available under this subchapter; and (C) the Secretary decides will enhance system-wide airport capacity significantly and meets the criteria of section 47115(d) of this title. (3) A letter of intent issued under paragraph (1) of this subsection is not an obligation of the Government under section 1501 of title 31, and the letter is not deemed to be an administrative commitment for financing. An obligation or administrative commitment may be made only as amounts are provided in authorization and appropriation laws. (4) The total estimated amount of future Government obligations covered by all outstanding letters of intent under paragraph (1) of this subsection may not be more than the amount authorized to carry out section 48103 of this title, less an amount reasonably estimated by the Secretary to be needed for grants under section 48103 that are not covered by a letter. (5) A letter of intent issued under paragraph (1) of this subsection may not condition the obligation of amounts on the imposition of a passenger facility fee. (f) NONALLOWABLE COSTS. —Except as provided in subsection (d) of this section and section 47118(f) of this title, a cost is not an allowable airport development project cost if it is for— (1) constructing a public parking facility for passenger automobiles; (2) constructing, altering, or repairing part of an airport building, except to the extent the building will be used for facilities or activities directly related to the safety of individuals at the airport; (3) decorative landscaping; or (4) providing or installing sculpture or art works. § 47111. Payments under project grant agreements (a) GENERAL AUTHORITY.— After making a project grant agreement under this subchapter and consulting with the sponsor, the Secretary of Transportation may decide when and in what amounts payments under the agreement will be made. Payments totaling not more than 90 percent of the United States Government's share of the project's estimated allowable costs may be made before the project is completed if the sponsor certifies to the Secretary that the total amount expended from the advance payments at any time will not be more than the cost of the airport development work completed on the project at that time. (b) RECOVERING PAYMENTS.— If the Secretary determines that the total amount of payments made under a grant agreement under this subchapter is more than the Government's share of the total allowable project costs, the Government may recover the excess amount. If the Secretary finds that a project for which an advance payment was made has not been completed within a reasonable time, the Government may recover any part of the advance payment for which the Government received no benefit.
