Description: NPMS PIPELINESThe National Pipeline Mapping System (NPMS) datasets are used to support the assessment of risk associated with the nation's hazardous liquid and gas pipeline infrastructure.The National Pipeline Mapping System (NPMS) includes a geographic information system (GIS) dataset containing the location and selected attributes of gas transmission and hazardous liquid pipelines, liquefied natural gas (LNG) plants and breakout tanks (BOT) under jurisdiction of the Pipeline and Hazardous Materials Safety Administration (PHMSA). Effective October 1, 2015, pipeline and LNG plant data is collected annually from pipeline operators as required by 49 CFR §§ 191.29 and 195.61. This metadata is for the national pipeline dataset. There is NPMS pipeline data for all 50 states as well as the District of Columbia and Puerto Rico. The NPMS pipeline dataset contains gas transmission and hazardous liquid pipelines subject to regulations from PHMSA. The NPMS pipeline dataset does not contain gas gathering, gas distribution, or hazardous liquid lines not subject to 49 CFR § 195.61 and can never be used in place of contacting a one call center prior to digging. Distribution of NPMS data in GIS format is handled for PHMSA by the National Repository and is limited to pipeline operators and local, state, tribal, and federal government officials and is subject to data access limitations and agreements. Fulfillments of data requests will include data only for the area of jurisdiction of the person requesting the data (data requests are fulfilled per county/counties, state, or the entire U.S.).Instructions for requesting NPMS data in a GIS format are outlined on the NPMS website at https://www.npms.phmsa.dot.gov/PipelineData.aspx.
