Executive Summary

Highway Account	$$ (Apportionment authorized by fiscal year)
Surface Transportation Program (STP) Interstate Maintenance (IM) National Highway System (NHS) Minimum Guarantee

Legislation from the Transportation Equity Act for the 21^st Century (TEA-21) increased significantly the amount of Federal apportionments that rely on the motor-fuel/HTF attribution process and factors. For example, under the current attribution process, more than $12 billion are apportioned annually to the States in TEA-21 Federal apportionments, compared to

$1-2 billion annually under preceding legislation. Also, all the States receive Federal apportionments through this process while under previous legislation only about 20 States did.

This brochure describes the motor-fuel/HTF process including some refinements and improvements FHWA is making after consultation with the States.

The first two sections of the brochure provide general background on the process; the third section describes the FHWA reassessment of the process. The fourth section describes refinements FHWA is making to ensure that data are reported and processed in a consistent manner. An implementation timetable for these refinements is also included. The fifth section describes an Implementation/Action Plan that will incorporate the latest in technology and management processes into the motor-fuel/HTF attribution process.
