National Pipeline Mapping System

The National Pipeline Mapping System (NPMS) is a comprehensive, official database that shows the locations of pipelines across the United States. It is maintained by the U.S. government to help ensure safety and awareness for industries, emergency responders, and the public. The system provides detailed maps and information about pipelines used for transporting oil, natural gas, and other hazardous liquids. By having accurate, accessible data, it helps prevent accidents, supports infrastructure planning, and promotes better response in case of emergencies. Overall, the NPMS is a vital tool for managing pipeline safety and transparency.
