The Pipeline and Hazardous Materials Safety Administration (PHMSA) Pipeline Safety 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 Pipeline Safety (OPS) is responsible for protecting people and the environment from pipeline failures by analyzing pipeline safety and accident data; evaluating which safety standards need improvement and where new rulemakings are needed; setting and enforcing regulations and standards for the design, construction, operation, maintenance or abandonment of pipelines by pipeline companies; educating operators, states and communities on how to keep pipelines safe; facilitating research and development into better pipeline technologies; training state and federal pipeline inspectors; and administering grants to states and localities for pipeline inspections, damage prevention and emergency response. The PHMSA Pipeline Safety Regions layer contains polygon features representing each of the five regions, Central, Eastern, Southern, Southwest, and Western, that make up PHMSA’s Office of Pipeline Safety. Each region office is charged with 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.
