Pipeline Safety Data Report Index

Welcome to the Pipeline Safety Data Report Index

This page provides access to a comprehensive collection of data reports compiled by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA). These reports offer transparency into the safety performance and infrastructure status of the nation’s pipeline systems.

Data collected from pipeline operators—both federally and state-regulated—are made publicly available to help identify safety trends, measure performance, and promote accountability across the pipeline industry. These datasets support PHMSA’s mission to improve industry communications, reduce risks, and ultimately prevent pipeline incidents, accidents, injuries, and fatalities.
