National Pipeline Mapping System

OPS and its State Partners inspect about 2.6 million miles of hazardous liquid and natural gas pipelines transporting the products from their origins to customers throughout the U.S. The map shown here is part of a secure mapping system.

Community Toolbox

PHMSA's mission is to protect people and the environment from the risks inherent in pipline transportation of energy products. Our mission cannot be accomplished in isolation. We are committed to working with all stakeholders to improve pipeline safety.

Find out how you can impact pipeline safety.

Safety Inspections

OPS and its State Partners conduct safety inspections of pipelines transporting natural gas from gathering fields (where natural gas is harvested from the earth) to homes and businesses. The blue line in this picture shows the portion of the nation’s natural gas system that the Federal regulators typically inspect. Learn more about the OPS inspection program.

Pipeline Materials

Hazardous liquid and natural gas pipelines are constructed out of a variety of materials. Cross country pipelines, which typically operate with higher pressures, are manufactured from steel plates in short 40-ft sections, called “joints”. Welders connect the joints end to end to create long lengths of pipeline. Steel pipelines come in a variety of longitudinal seams, including a spiral weld or straight, and some have no seam at all (seamless pipe).

Notice – Website in Transition

To better serve you and in an effort to consolidate information, the Pipeline and Hazardous Materials Safety Administration (PHMSA) is phasing out the Pipeline Safety Awareness website on August 31, 2015.  The content from this website has been transitioned to the PHMSA website. Links to the most frequently visited webpages from the Pipeline Safety Awareness website are listed below; we encourage you to bookmark these new locations.  If you have any questions or feedback, please contact the Office of Pipeline Safety at 202-366-4595 or by email at PHMSA.Pipelinesafety@dot.gov.

State Pipeline Legal Forum Webcast

PHMSA Administrator Cynthia Quarterman requested the Office of Chief Counsel to launch an outreach effort to increase ties between pipeline state counterparts and pipeline program attorneys.  PHMSA's  Office of Chief Counsel hosted a State Pipeline Legal Forum webcast on December 8, 2011.  Recent pipeline incidents have highlighted the need for both federal and state pipeline regulators to beef up their pipeline safety programs and to prevent similar accidents in the future.  The webcast allowed the Office of Chief Counsel staff to introduce themselves, meet state legal colleagues, explain the pipeline work Counsel does, and solicit input on how PHMSA and state offices can more effectively work together.
