In subsection (a), before clause (1), the words "Except as provided in subsections (b) and (c) of this section" are substituted for "Except as otherwise provided in this chapter" because subsections (b) and (c) restate the only parts of the chapter that provide exceptions to the general rule stated in subsection (a). In clauses (1) and (2), the words "for a project" are substituted for "payable on account of any project contained in an approved project grant application submitted in accordance with this chapter" in 49 App.:2209(a) and "payable on account of any project contained in an approved project grant application" in 49 App.:2209(b) for consistency in this chapter and to eliminate unnecessary words. A project cost is allowable only if it is incurred under a grant agreement made under the chapter, and a grant agreement may be made only if the project grant application is approved. In clause (1), the words "number of passenger boardings" are substituted for "enplaning . . . of the . . . passengers enplaned" because of the definition of "passenger boardings" in section 47102 of the revised title.

In subsection (b), the words "If, under subsection (a) of this section, the Government's share of allowable costs . . . is less than the share applied on June 30, 1975, under section 17(b) of the Airport and Airway Development Act of 1970" and "(3) the percentage necessary to increase the Government's share to the percentage that applied on June 30, 1975, under section 17(b) of the Act" are substituted for 49 App.:2209(c) (last sentence) for clarity. The words "of the total of all lands therein" are omitted as surplus.

In subsection (c), the words "Notwithstanding subsections (a) and (b) of this section" are substituted for "Notwithstanding any other provision of this chapter" because subsections (a) and (b) are the only other parts of the chapter that specify the United States Government's share of allowable project costs.
