Highway Routing of Hazardous Materials: Guidelines for Applying Criteria

This document is a revision of the July 1985 U.S Department of Transportation (DOT) publication entitled Guidelines for Applying Criteria to Designate Routes for Transporting Hazardous Materials (DOT/RSPA/OHMT-89-02), and reflects the new regulations regarding highway routing of non-radioactive hazardous materials (NRHM) (49 CFR Part 397). This document provides guidance to States, Indian tribes, and locals on how to apply and implement the new Federal standards for establishing, maintaining, and enforcing designated NRHM highway routes. It is important to note that there are two types of routing designations: designated routes and restricted routes. Designated routes are those highway routes on which NRHM must be transported. Restricted routes are those highway routes on which NRHM may not be transported. Restrictions addressed by the new regulations include tunnels, lane restrictions, time of day limitations, prior notice, escort requirements, etc.; jurisdictional restrictions such as "nuclear free zone" are not covered. Both designated and restricted zones are covered in this Guide.
