(1) The Secretary of the Treasury, not less frequently than once in each calendar quarter, after consultation with the Secretary of Transportation, shall estimate— (A) the amount which would (but for this subsection) be the unfunded highway authorizations at the close of the next fiscal year, and (B) the net highway receipts for the 48-month period beginning at the close of such fiscal year. (2) If the Secretary of the Treasury determines for any fiscal year that the amount described in paragraph (1)(A) exceeds the amount described in paragraph (1)(B)— (A) he shall so advise the Secretary of Transportation, and (B) he shall further advise the Secretary of Transportation as to the amount of such excess. (A) If, before any apportionment to the States is made, in the most recent estimate made by the Secretary of the Treasury there is an excess referred to in paragraph (2)(B), the Secretary of Transportation shall determine the percentage which— (i) the excess referred to in paragraph (2)(B), is of (ii) the amount authorized to be appropriated from the Trust Fund for the fiscal year for apportionment to the States. (B) If the Secretary of Transportation determines a percentage under subparagraph (A) for purposes of any apportionment, notwithstanding any other provision of law, the Secretary of Transportation shall apportion to the States (in lieu of the amount which, but for the provisions of this subsection, would be so apportioned) the amount obtained by reducing the amount authorized to be so apportioned by such percentage. (4) If, after funds have been withheld from apportionment under paragraph (3)(B), the Secretary of the Treasury determines that the amount described in paragraph (1)(A) does not exceed the amount described in paragraph (1)(B) or that the excess described in paragraph (1)(B) is less than the amount previously determined, he shall so advise the Secretary of Transportation. The Secretary of Transportation shall apportion to the States such portion of the funds so withheld from apportionment as the Secretary of the Treasury has advised him may be so apportioned without causing the amount described in paragraph (1)(A) to exceed the amount described in paragraph (1)(B). Any funds apportioned pursuant to the preceding sentence shall remain available for the period for which they would be available if such apportionment took effect with the fiscal year in which they are apportioned pursuant to the preceding sentence.

(B) The term “net highway receipts” means, with respect to any period, the excess of— (i) the receipts (including interest) of the Highway Trust Fund during such period, over (ii) the amounts to be transferred during such period from such Fund under subsection (c) (other than paragraph (1) thereof). (6) For purposes of making any estimate under paragraph (1) of net highway receipts for periods ending after the date specified in subsection (b)(1), the Secretary shall treat— (A) each expiring provision of subsection (b) which is related to appropriations or transfers to the Highway Trust Fund to have been extended through the end of the 48-month period referred to in paragraph (1)(B), and (B) with respect to each tax imposed under the sections referred to in subsection (b)(1), the rate of such tax during the 48-month period referred to in paragraph (1)(B) to be the same as the rate of such tax as in effect on the date of such estimate. (7) Any estimate under paragraph (1) and any determination under paragraph (2) shall be reported by the Secretary of the Treasury to the Committee on Ways and Means of the House of Representatives, the Committee on Finance of the Senate, the Committees on the Budget of both Houses, the Committee on Public Works and Transportation of the House of Representatives, and the Committee on Environment and Public Works of the Senate. (1) There is established in the Highway Trust Fund a separate account to be known as the “Mass Transit Account” consisting of such amounts as may be transferred or credited to the Mass Transit Account as provided in this section or section 9602(b). (2) The Secretary of the Treasury shall transfer to the Mass Transit Account the mass transit portion of the amounts appropriated to the Highway Trust Fund under subsection (b) which are attributable to taxes under sections 4041 and 4081 imposed after March 31, 1983.
