It became an independent agency under the Emergency Price Control Act, January 30, 1942. The OPA had the power to place ceilings on all prices except agricultural commodities, and to ration scarce supplies of other items, including tires, automobiles, shoes, nylon, sugar, gasoline, fuel oil, coffee, meats and processed foods. At the peak, almost 90% of retail food prices were frozen. It could also authorize subsidies for production of some of those commodities.Herman, Arthur.
