Description: The Pipeline and Hazardous Materials Safety Administration (PHMSA) HazMat Regions dataset was compiled on October 04, 2022 from the Pipeline and Hazardous Materials Safety Administration (PHMSA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). PHMSA’s Office of Hazardous Materials Safety (OHMS) carries out a national safety program, including security matters, to protect against the risks to life and property inherent in the transportation of hazardous materials in commerce by all transportation modes. The PHMSA HazMat Regions layer contains polygon features representing each of the five regions— Central, Eastern, Southern, Southwest, and Western—that make up PHMSA’s Office of Hazardous Materials Safety. Each region office is charged with overseeing the safe and secure movement of daily shipments of hazardous materials by all modes of transportation. Despite regional divisions the jurisdiction of PHMSA staff is nationwide and not limited to their regional area of responsibility.
