What the agency says
U.S. Customs and Border Protection (CBP) is proposing to withdraw the international airport designation of Chalk Seaplane Base, now operating as Miami Seaplane Base. This proposal is based on evidence that the facility at this location has not been in compliance with CBP regulatory and security standards and the amount of business clearing through the airport does not justify continued maintenance of inspection equipment and personnel. The proposed change is part of CBP's continued efforts to use its personnel, facilities, and resources more efficiently and to provide better service to carriers, importers, and the public.
