The Pipeline and Hazardous Materials Safety Administration (PHMSA), within the Department of Transportation (DOT), is the federal agency charged with the safe and secure movement of almost 1 million daily shipments of hazardous materials by all modes of transportation. The agency also overseas the nation's pipeline infrastructure which accounts for 64 percent of the energy commodities consumed in the United States. The Office of Hazardous Materials Safety (OHMS) is the federal safety authority for the transportation of hazardous materials by air, rail, highway and water.
This website includes OHMS guidance documents, hazmat carriers' special permits and approvals information, reports and incidents summaries, penalty action reports, registration information and forms, the Emergency Response Guidebook for First Responders, Freedom of Information Act requests, and the Hazardous Materials Emergency Preparedness (HMEP) grants program. This site also provides the ability for the public to use electronic filing to reduce the amount of data entered manually from paper submissions, improve data quality, and speed the process for requests for information.
