This final rule removes undue regulatory burdens by adopting the provisions of U.S Department of Transportation (DOT) special permit (SP) 21287 to streamline the transportation of refrigerating machines-- including common household appliances like refrigerators, window- mounted air-conditioning units, and dehumidifiers--that contain small quantities of certain low flammability refrigerant gases.
