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.

Users are advised to read the rest of the metadata record carefully for additional details. The USDOT region layer for the Pipeline and Hazardous Materials Safety Administration (PHMSA) Office of Hazardous Materials Safety was created by the Bureau and Transportation Statistics (BTS), then approved by a member of the PHMSA. BTS communicated with PHMSA personnel to help understand where the PHMSA Regions are and which areas it should encompass, mostly adhering to the regions listed via a map/table/text on PHMSA’s website https://www.phmsa.dot.gov/about-phmsa/offices. As a result, Esri’s ArcPro (or any geospatial software) was utilized in creating polygons, using the U.S. Census state 2020 TIGER/Line shapefile to designate the PHMSA regional boundaries by dissolving the Census state file to represent one cohesive entity/region. To populate the attributes, BTS communicated with the PHMSA to understand the address and contact information for each region via their website. Various fields were then added to the database schema to accommodate this information using the “add field” function within ArcGIS Pro, and then derived from the PHMSA’s website, filled out appropriately by BTS with PHMSA’s guidance and ultimate approval. data is updated as deemed necessary Leigha Gooding Pipeline and Hazardous Materials Safety Administration (PHMSA) Supervisory Physical Scientist 202-366-0667 1200 New Jersey Ave. SE Washington DC 20590 United States Leigha.Gooding@dot.gov party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
