Pipeline and Hazardous Materials Safety Administration
The Pipeline and Hazardous Materials Safety Administration (PHMSA) was established on November 20, 2004 under the Norman Y. Mineta Research and Special Programs Improvement Act of 2004 (Pub. L. 108-426).
PHMSA was created to protect the American public and the environment by ensuring the safe and secure movement of hazardous materials to industry and consumers by all transportation modes, including the nation's pipelines. Through PHMSA, the Department develops and enforces regulations for the safe, reliable, and environmentally sound operation of the nation's 2.3 million mile pipeline transportation system and the nearly 1 million daily shipments of hazardous materials by land, sea, and air.
