The Pipeline and Hazardous Materials Safety Administration (PHMSA) was formerly the Office of Hazardous Materials Transportation and the Materials Transportation Bureau. Its mission is to promote the safe transportation of hazardous materials on roadways, railways, and through pipelines. It was established in 1975.
The Government Documents Collection provides access to PHMSA regulations and guidance about pipelines and transport of hazardous materials. We also have Congressional reports, documents, and hearings about pipelines and hazardous materials.
