Pipeline Location

The map below shows major oil and natural gas transmission pipelines in the U.S. Transmission lines are used to transport oil and natural gas from gathering systems to processing, storage or refining centers, and eventually on to customers.

National map of oil and gas pipelines

The United States has the largest network of energy pipelines in the world, with more than 2.7 million miles of pipe. There are approximately 80,000 miles of crude oil lines in the U.S. that connect regional markets.

The National Pipeline Mapping System (NPMS) publishes pipeline location information county by county that is publicly available. Government officials and emergency response officials have access to more detailed information. Public stakeholders can also identify who’s operating pipelines in their area by state, county or zip code as well as information about the pipeline operator that is maintained by the Pipelines and Hazardous Materials Safety Administration (PHMSA).

Nearly the entire mainline pipe is buried. Other pipeline components such as pump stations are above ground. Some lines are as short as a mile, while others may extend 1,000 miles or more.
