Anne Arundel County, Maryland, enacted two related ordinances. One absolutely prohibited the disposal in and the transportation through Anne Arundel County of various hazardous wastes not originating in that county. Another ordinance required a license to dispose of hazardous waste in Anne Arundel County; it also required a license to transport hazardous wastes through the county. Browning-Ferris, Inc. (BFI), is the owner and operator of a landfill located in Anne Arundel County that is licensed by the state of Maryland to receive hazardous wastes. BFI is also a hauler of hazardous wastes within the county. The county notified BFI that it expected BFI to comply with the new regulations, and BFI filed a lawsuit challenging the ordinances and seeking to have them enjoined. How should the court rule?
