About the Pipeline Information Management Mapping Application (PIMMA)
The Pipeline and Hazardous Materials Safety Administration (PHMSA) has developed the Pipeline Information Management Mapping Application (PIMMA) for use by
pipeline operators and federal, tribal, state, and local government officials only. The application 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 PIMMA.
If you would like to request GIS data layers for use in your own mapping system,
please submit a Data Request.
An iPhone app for PIMMA is also available. To download it, from your iPhone search for “pipeline information” on the App Store. You will need your PIMMA username and password to use the app. All rules associated with the PIMMA desktop version also apply to the PIMMA iPhone app. The app is not compatible with Android or Blackberry devices.
PIMMA is intended to be used solely by the person who is given access by PHMSA.
Your username and password should not be shared with other persons either within or outside of your organization.
However, if you have a consultant/subcontractor working on your behalf, you may opt to share your PIMMA account with your consultant provided you have a confidentially agreement with the consultant in place that states that the login will only be used for the purposes of the project and will not be redistributed.
Otherwise, if another person expresses interest in using PIMMA, please have them submit an application.
PHMSA monitors user activity and reserves the right to remove individual access rights.
Access to PIMMA is limited to federal, tribal, state, and local government officials as well as pipeline operators. PIMMA access cannot be given to any person who is not a direct official/employee of a government agency or a pipeline operator. All applications will be processed by PHMSA personnel, who will respond as soon as possible. The general public and private companies may not access PIMMA;
please utilize the NPMS Public Map Viewer instead.
If you have a PIMMA account but have forgotten your username or password, please visit the Forgot PIMMA Login tool for assistance.
Federal Government (FEDERAL AND MILITARY OFFICIALS ONLY):
Federal government officials wishing to obtain PIMMA access for the entire nation should apply via the Federal Government application.
If you are a federal official who only needs access to one or many states or counties, please submit the Federal Government application and then email npms@dot.gov clarifying the specific state(s) or county(ies) requested.
Tribal Government:
Tribal government officials will be granted access to the counties that contain their tribal jurisdictional area as determined by the US Census’ American Indian/Alaska Native/Native Hawaiian Areas designation. If access to only a subset of this area is needed, please email npms@dot.gov after completing your application to detail the specific counties for which data is needed.
State and Local Government:
State and Local Government officials may request access to the State and Local Government PIMMA by filling out and submitting an online application. Applicants will only be granted access to the jurisdiction they are employed by.
Pipeline Operator (INCLUDES PIPELINE, LNG PLANT, AND BREAKOUT TANK OPERATORS):
Pipeline operators will only be granted access to their respective pipeline facilities (pipelines, LNG plants and/or breakout tanks), as defined by the Operator ID. Pipeline operators may not access pipeline facilities they do not operate. Operators requesting access should apply via the Pipeline Operator application.
