Minimum cost share for a Performance Partnership Grant.

§ 35.147 Minimum cost share for a Performance Partnership Grant. (a) To calculate the cost share for a Performance Partnership Grant (see §§ 35.130 through 35.138) in the initial and subsequent years that it includes section 105 funds, the minimum cost share contribution for the section 105 program will be the match requirement set forth in § 35.145, or the maintenance of effort established under § 35.146 in the first year that the section 105 grant is included in a Performance Partnership Grant, whichever is greater. (b) If an air pollution control agency includes its section 105 air program funding in a Performance Partnership Grant and subsequently withdraws that program from the grant: (1) The required maintenance of effort amount for the section 105 program for the first year after the program is withdrawn will be equal to the maintenance of effort amount required in the year the agency included the section 105 program in the Performance Partnership Grant. (2) The maximum federal share for the section 105 program in the first and subsequent years after the grant is withdrawn may not be more than three-fifths of the approved cost of the program. (c) The Regional Administrator may approve an exception from paragraph (b) of this section upon determining that exceptional circumstances justify a reduction in the maintenance of effort, including when an air pollution control agency reduces section 105 funding as part of a non-selective reduction of the programs of all executive branch agencies of the applicable unit of government.
