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.

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 Pipeline 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
