This section sets forth the Tribal Transportation Allocation Methodology (TTAM) that BIA uses to allocate IRR Program funds. After appropriate statutory and regulatory set-asides, as well as other takedowns, the remaining funds are allocated as follows: [GRAPHIC] [TIFF OMITTED] TR19JY04.001
(a) A statutorily determined percentage to a tribal transportation planning program (under 23 U.S.C. 204(j)); and
(b) The remainder to a pool of funds designated as ``Remaining funding available for distribution.'' This ``Remaining funding available for distribution'' pool is further allocated as follows:
(1) 5 percent to a discretionary pool for IRR High Priority Projects (IRRHPP); and
(2) 95 percent to pool for distribution by the following Relative Need Distribution Factor (RNDF) as defined in Sec. 170.223: (50 percent Cost to Construct + 30 percent Vehicle Miles Traveled + 20 percent Population)
(3) If the annual authorization is greater than $275 million, then the amount above $275 million, after appropriate statutory and regulatory set-asides, as well as other takedowns are applied, will be allocated as follows:
(i) 12.5 percent to the IRRHPP (Sec. 170.205);
(ii) 12.5 percent to the Population Adjustment Factor (PAF) (Sec. 170.220); and
(iii) 75 percent to the RNDF (Sec. 170.223).
