What is NPMS? • National GIS dataset of gas transmission and hazardous liquid pipelines, LNG facilities, and breakout tanks (voluntary) from data submitted by operators • NPMS data can be viewed online through • PIMMA – access for local government, password-protected • Public Viewer - open access, view one county per session, no password needed • Raw NPMS dataset for import into local government GIS system (such as ESRI ArcGIS) • Does not contain information on interconnects, pump and compressor stations, valves, direction of flow, capacity, throughput, or operating pressure. • Does not contain distribution and gathering pipelines.
Pipeline Attributes • PHMSA-assigned operator identification number • Operator name & contact information • System name • Subsystem name • Diameter (voluntary) • Commodities transported • Interstate/intrastate designation • Operating status (in service, abandoned, retired) • Geospatial accuracy estimate (nominal accuracy is +/-500’) • Required to be updated annually
PIMMA vs. the Public Viewer Public Viewer • Allows user to view, query, and print custom pipeline maps • Extent is limited to one county per session • High Consequence Area population layers are visible; drinking water and ecological layers are not • Zoom extent is limited to 1:24,000 • Sensitive attributes (diameter and data accuracy) are not visible PIMMA • Allows user to view, query, and print custom pipeline maps • Federal users can see the entire U.S. pipeline network • High Consequence Area (HCA) layers are visible • Zoom extent is unlimited • Sensitive attributes (diameter and data accuracy) are visible
Role of NPMS within PHMSA PHMSA uses NPMS data for tasks such as • Asset management and analysis • Emergency response • Decision support and policy making • Inspection preparation • Validating Annual Report statistics and mileage • Locating noncompliant operators …The NPMS website receives 6,000+ visitors per month www.npms.phmsa.dot.gov
Future Direction • Integrating NPMS pipeline data with tabular datasets such as inspection records, accident/incident reports, and special permit data • Creating a “history” for each pipeline segment which will allow PHMSA to track its operator and records over time • Considering rulemaking to expand attributes collected and improvedata accuracy
