The Pipeline and Hazardous Materials Safety Administration (PHMSA) has developed the Pipeline Information Management Mapping Application (PIMMA) for use by pipeline operators and federal, 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.

PIMMA is intended to be used solely by the person who is given access by PHMSA. Your user name and password should not be shared with other persons either within or outside of your organization. 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, 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.
