Learn About PHMSA Programs

Energy products and hazardous materials support the American economy and our way of life. Americans use oil and natural gas everyday to heat, cool and light our homes and businesses, travel to work, and provide raw material for the many other things we use, including plastics, fibers, and paints. We also use a variety of chemicals to clean our water, create medicines, fertilize crops, and manufacture clothing and many other essential commodities.

PHMSA is charged with ensuring the transportation of these chemicals and energy products are conducted in the safest possible manner, free of risk to the American public, property and the environment, regardless of the transportation mode.  To learn more about PHMSA’s hazardous materials and pipeline safety programs, including the issuance of regulations and ensuring compliance through inspections and enforcement, visit the links below.
