The Pipeline and Hazardous Materials Safety Administration has developed the Pipeline Information Management Mapping Application (PIMMA) for use by NPMS pipeline operators and federal, tribal, state, and local government officials, including emergency responders and government or pipeline operator contract staff. The application contains sensitive pipeline critical infrastructure information that is Controlled Unclassified Information (CUI). PIMMA is intended to be used solely by the person who is given access by the Pipeline and Hazardous Materials Safety Administration. Do not share your username and password with other persons either within or outside of your organization. If another person expresses interest in using PIMMA, please have them contact the Pipeline and Hazardous Materials Safety Administration directly to obtain access.
