The Federal Motor Carrier Safety Administration (FMCSA) published a Notice in the Federal Register on August 8, 2016, providing the most current revisions to the National Hazardous Materials Route Registry (NHMRR). The agency’s notice also offers procedures to facilitate the update of the NHMRR by State and Tribal government routing agencies.

The NHMRR is a listing, as reported by States and Tribal governments, of all designated and restricted road and preferred highway routes for transportation of highway route controlled quantities (HRCQ) of Class 7 radioactive materials (RAM) (HRCQ/RAM) and non-radioactive hazardous materials (NRHMs).

The most up-to-date version of the NHMRR, was published in a Federal Register Notice on April 29, 2015. Since the publication of the April 29 Notice, the State of California has notified the FMCSA of revisions to the Route Registry.

The revisions are effective August 8, 2016. For the updated list of routes visit the FMCSA website.
