Action
Supplemental Notice of Proposed Rulemaking (SNPRM).
Summary
The FHWA is proposing the National Tunnel Inspection Standards (NTIS) for highway tunnels. The FHWA previously proposed the NTIS in a notice of proposed rulemaking (NPRM) published in the Federal Register on July 22, 2010. On July 6, 2012, the President signed the Moving Ahead for Progress in the 21st Century Act (MAP-21), which requires the Secretary to establish national standards for tunnel inspections. The MAP-21 requires that NTIS contain a number of provisions that were not included in the proposal set forth in the earlier NPRM. As a result, FHWA is issuing this SNPRM to request comment on a revised NTIS proposal that incorporates the provisions required by MAP-21. This SNPRM proposes requirements for tunnel owners, including the establishment of a program for the inspection of highway tunnels, maintenance of a tunnel inventory, reporting of the inspection findings to FHWA, and correction of any critical findings identified during these inspections.
