NPMS External Pipeline Attribute Data Dictionary
Last update: March 2023
This data dictionary describes the pipeline attribute data that is available to external stakeholders from the National Pipeline Mapping System (NPMS). The NPMS pipeline data only includes gas transmission pipelines and hazardous liquid pipelines subject to Part 195 regulations. Some of these attributes are submitted to PHMSA by the pipeline operator. Some are incorporated into the NPMS pipeline data by PHMSA.
NPMS pipeline data always reflects the pipeline segment's operational status during the reporting year. View the REVIS_DATE (REVISION DATE) to determine the reporting year on each pipeline segment. A revision date during 2023 reflects reporting year 2022 (operations as of 12/31/2022).
You can read more about the NPMS pipeline data in the metadata available on the NPMS GIS Data Request page on the NPMS website at: https://www.npms.phmsa.dot.gov/PipelineData.aspx. This metadata file will have additional detail that relates to the attribute values available in a GIS data request.
You can read more about the current NPMS submission standards and submission procedures from the Pipeline Operator section of the NPMS website.

PHMSA has approval to start collecting additional pipeline attributes, as well as LNG and Breakout Tank related data layers and attributes in the NPMS. PHMSA will update this data dictionary once we collect and make this data available to external stakeholders. Details about the new attributes, timelines for collection, and which will be available to the public are outlined in this document from the NPMS website: https://www.npms.phmsa.dot.gov/Documents/Updated%20Attributes%20Standards%20and%20Revision%20Summary.pdf
