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. You can learn about the National Pipeline Mapping System and pipelines in your county by clicking on the following links:
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.
Learn How to Recognize Where a Pipeline Is, How to Recognize a Pipeline Release, and What to DO in the event of a suspected or detected leak. Click here to learn more.
What are pipelines? Where are they? And why do we need them in the first place? Those are good, basic questions. Click here to read about Pipeline 101.
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.
Up-to-date information detailing pipeline operators’ efforts to replace aging gas distribution pipelines, including inventories of cast and bare steel pipelines per state or operator.
The Pipeline Safety Update provides the actions taken by USDOT, the states, communities and pipeline operators.
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).
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.
