Pipeline Info Mgmt Mapping

The Pipeline and Hazardous Materials Safety Administration’s (PHMSA) National Pipeline Mapping System (NPMS) has developed the mobile Pipeline Information Management Mapping Application (PIMMA) app for use by pipeline operators and federal, state, and local government officials only. The app contains hazardous liquid and gas transmission pipelines, Liquefied Natural Gas (LNG) plants and breakout tank data. PIMMA data is for reference purposes only; data cannot be downloaded from the mobile PIMMA app. Usage of the app is password protected. If you do not already have a PIMMA login, please visit the NPMS website at https://www.npms.phmsa.dot.gov/ to apply for access. All questions regarding the app should be directed to NPMS staff at npms@dot.gov or 703-317-6294. This app must not be used for digging or excavation purposes. Call 811 before you dig.

Functionality of the mobile PIMMA app includes:
- Viewing the spatial location of and attribute information for hazardous liquid and gas transmission pipelines, LNG plants, breakout tanks and pipeline accidents and incidents data within your jurisdiction,
- Locating hazardous liquid and gas transmission pipelines within five miles of your current location,
- Querying hazardous liquid and gas transmission pipelines,
- Measuring distances, and
- Emailing a screen capture of the current map view.
