PHMSA's Office of Pipeline Safety (OPS) provides a variety of data about federally-regulated and state-regulated natural gas pipelines, hazardous liquid pipelines, and liquefied natural gas (LNG) plants. The operators of these pipeline facilities report this data in accordance with Part 191 and Part 195 of PHMSA’s pipeline safety regulations. PHMSA provides downloads of the raw data, yearly summaries, multi-year trends of safety performance metrics, and inventories tracking the removal of aging and other higher-risk infrastructure.
