PADDs

The United States is divided into five refining districts, which make up the Petroleum Administration for Defense Districts (PADDs).  The districts were created during World War II under the Petroleum Administration for War to help organize the allocation of fuels derived from petroleum products, including gasoline and diesel (or “distillate”) fuel. Although the administration was eliminated in 1946, Congress passed the Defense Production Act of 1950, which created the Petroleum Administration for Defense and used the same five districts. Today, these regions are still used for data collection purposes.

This map shows an overview of the U.S. PADDs and where refineries are located today.
