23 C.F.R. § 515.13
(a) Process certification and recertification under 23 U.S.C. 119(e)(6). Not later than 90 days after the date on which the FHWA receives a State DOT's processes and request for certification or recertification, the FHWA shall decide whether the State DOT's processes for developing its asset management plan meet the requirements of this part. The FHWA will treat the State DOT's submission of an initial State-approved asset management plan under § 515.11(b) as the State DOT's request for the first certification of the State's DOT's plan development processes under 23 U.S.C. 119(e)(6). As provided in paragraph (c) of this section, State DOT shall update and resubmit its asset management plan development processes to the FHWA for a new process certification at least every 4 years.
(b) Annual determination of consistency under 23 U.S.C. 119(e)(5). Not later than August 31, 2019, and not later than July 31 in each year thereafter, FHWA will notify the State DOT whether the State DOT has developed and implemented an asset management plan consistent with 23 U.S.C. 119. The notice will be in writing and, in the case of a negative determination, will specify the deficiencies the State DOT needs to address. In making the annual consistency determination, the FHWA will consider the most recent asset management plan submitted by the State DOT, as well as any documentation submitted by the State DOT to demonstrate implementation of the plan. The FHWA determination is only as to the consistency of the State DOT asset management plan and State DOT implementation of that plan with applicable requirements, and is not an approval or disapproval of strategies or other decisions contained in the plan. With respect to any assets the State DOT may elect to include in its plan in addition to NHS pavement and bridge assets, the FHWA consistency determination will consider only whether the State DOT has complied with § 515.9(l) with respect to such discretionary assets.
(2) Plan implementation. The State DOT must demonstrate implementation of an asset management plan that meets the requirements of 23 U.S.C. 119 and this part. Each State DOT may determine the most suitable approach for demonstrating implementation of its asset management plan, so long as the information is current, documented, and verifiable. The submission must show the State DOT is using the investment strategies in its plan to make progress toward achievement of its targets for asset condition and performance of the NHS and to support progress toward the national goals identified in 23 U.S.C. 150(b). The State DOT must submit its implementation documentation not less than 30 days prior to the deadline for the FHWA consistency determination.
