[Code of Federal Regulations] [Title 23, Volume 1] [Revised as of April 1, 2002] From the U.S. Government Printing Office via GPO Access [CITE: 23CFR420.115] [Page 86] TITLE 23--HIGHWAYS CHAPTER I--FEDERAL HIGHWAY ADMINISTRATION, DEPARTMENT OF TRANSPORTATION PART 420--PLANNING AND RESEARCH PROGRAM ADMINISTRATION--Table of Contents Subpart A--Administration of FHWA Planning and Research Funds Sec. 420.115 Approval and authorization procedures. (a) The STA and its subrecipients shall obtain work program approval and authorization to proceed prior to beginning work on activities in the work program. Such approvals and authorizations should be based on final work program documents. The STA and its subrecipients also shall obtain prior approval for budget and programmatic changes as specified in 49 CFR 18.30 and for those items of allowable costs which require prior approval in accordance with the applicable cost principles specified in 49 CFR 18.22. (b) Except for advance construction, authorization to proceed with the work program(s) in whole or in part shall be deemed a contractual obligation of the Federal Government pursuant to 23 U.S.C. 106 and shall require that appropriate funds be available for the full Federal share of the cost of work authorized. Those STAs that do not have sufficient FHWA planning and research funds or obligation authority available to obligate the full Federal share of the entire work program(s) may utilize the advance construction provisions of 23 U.S.C. 115(a) in accordance with the requirements of 23 CFR Part 630, subpart G. The STAs that do not meet the advance construction provisions, or do not wish to utilize them, may request authorization to proceed with that portion of the work program(s) for which FHWA planning and research funds are available. In the latter case, authorization to proceed may be given for either selected work activities or for a portion of the program period, but such authorization shall not constitute a commitment by the FHWA to fund the remaining portion of the work program(s) should additional funds become available. (c) A project agreement shall be executed by the STA and FHWA Division Office for each statewide transportation planning, metropolitan planning area transportation planning, or RD&T work program, individual activity or study, or any combination administered as a single Federal- aid project. The project agreement shall be executed after the authorization has been given by the FHWA to proceed with the work in whole or in part. In the event that the project agreement is executed for only part of the work program, the project agreement shall be amended when authorization is given to proceed with additional work.
