Positioning, Navigation, and Timing (PNT) Service for National Critical Infrastructure Resiliency
This RFI provides an outline for the potential use by the Federal Government of one or more Positioning, Navigation, and Timing (PNT) technologies to back up signals from the Global Positioning System (GPS) and to ensure resiliency of PNT for U.S. Critical Infrastructure (CI) operations. As a co-chair and member of the National Executive Committee for Space-based PNT, and a provider and user of U.S. critical infrastructure services, the Department of Transportation is investigating opportunities by which the Federal Government may make use of service(s) which can provide the necessary backup capability or capabilities to ensure PNT continuity for U.S. CI in the event of a temporary disruption in GPS availability. Further, as the lead civil agency for PNT in the Federal Government, the Department of Transportation is interested in leveraging PNT service technology initiatives under consideration or currently undertaken by industry. The Federal Government is presently documenting civil requirements for PNT capabilities to serve as the basis for potential future acquisition activity. The initial objective is to support sustainment of domestic CI timing continuity with the capability to extend service(s) in the future to provide positioning/navigation continuity as well.
Proposed Amendment to the Third Renewed Memorandum of Understanding (MOU) Assigning Certain Federal Environmental Responsibilities to the State of California, Including National Environmental Policy Act (NEPA) Authority for Certain Categorical Exclusions (CEs)
The FHWA and the State of California acting by and through its Department of Transportation (Caltrans), propose an amendment to the Memorandum of Understanding (MOU) authorizing the State's participation in the 23 U.S.C. 326 program. This program allows FHWA to assign to States its authority and responsibility for determining whether certain designated activities within the geographic boundaries of the State are categorically excluded from preparation of an Environmental Assessment or an Environmental Impact Statement under the National Environmental Policy Act. The parties propose to amend the MOU to make the litigation provisions consistent with the 23 U.S.C. 327 program MOU and to allow a 90 day suspension of the program, giving the State an opportunity to renew its waiver of sovereign immunity and acceptance of Federal court jurisdiction. The program will resume upon the State's recertification that the sovereign immunity waiver and acceptance of Federal court jurisdiction is in place.
