Appendix C: Federal-Aid Sources of SIB Capitalization Funds

As of February 28, 1997, the six States so far obligating funds to SIB capitalization had employed funding from five separate Federal-aid funding categories: Highway Bridge Replacement and Rehabilitation Program (HBRRP), NHS, Interstate Maintenance (IM), Minimum Allocation (MA), and the Surface Transportation Program (STP). Among these five categories, the NHS program has proven the most popular choice for SIB capitalization, with five of the six States obligating funds for this purpose. In dollar terms, however, States have relied most heavily on funding for the Interstate Maintenance program, which constitutes 30 percent of the total funds obligated to date for SIB capitalization. Exhibit C.1 displays the current SIB capitalization patterns across the six States that had obligated funds for SIB capitalization as of February 28, 1997.

This table reflects only obligations associated with ACAP declared in fiscal year 1996.

Most State officials note that they chose which categories to tap on the basis of the availability of reasonably large unobligated balances of apportioned funding in those categories. The presence of these balances indicated that there was sufficient "room" in the apportionment for that category to support additional obligations of associated funds. Most State officials report that there is little or no linkage between the Federal-aid highway categories usedto capitalize the SIBs and the highway projects ultimately expected to be supported by the SIB.
