Welcome to the NPMS Submission Reviewer
The National Pipeline Mapping System (NPMS) Submission Reviewer is for use by pipeline, LNG plant and breakout tank (BOT) operators only. It supports the submission review process by enabling operators to review the accuracy of their submitted pipeline, LNG plant or BOT data before it becomes live on the NPMS Pipeline Information Management Mapping Application (PIMMA) site.
