Public-Private Partnerships that involve a Federal or federally-assisted project, are subject to Federal laws. However, in some circumstances, the Federal requirements for Public-Private Partnerships apply differently to projects with more significant private sector involvement or there is other flexibility in the law that can be used by a Public-Private Partnership. We have tried to identify these circumstances in this Manual. Further, we have undertaken a number of efforts that would streamline Federal requirements to eliminate duplication and delay and to make the process more reliable. These initiatives can help make participation in highway projects more attractive for the private sector.
