PHMSA Office Locations

The Pipeline and Hazardous Materials Safety Administration (PHMSA) Office Locations 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). The PHMSA Office Locations layer contains point features representing the addresses of PHMSA’s regional and field operations offices as well as its Headquarters and Inspector Training and Qualifications Division office. Each region office is charged with overseeing the safe and secure movement of daily shipments of hazardous materials by all modes of transportation, as well as ensuring the safe, reliable, and environmentally sound operation of the nation's pipeline infrastructure. Despite regional divisions the jurisdiction of PHMSA staff is nationwide and not limited to their regional area of responsibility.

In some cases, both the Office of Pipeline Safety and the Office of Hazardous Materials Safety are located at the same address. In these cases, the data layer still contains a separate point for each office so that the contact information for each office can be provided. Although the PHMSA Headquarters and the Inspector Training and Qualifications Division represent both the OPS and the OHMS, there is only one point for each of these offices since there is only one contact for each office.
