A larger U.S. Customs and Border Protection Facility was opened in 2014 in a former air cargo building. The facility processes international passengers arriving on general aviation flights. No airlines use this facility. It has a processing room, an interview room, space for agricultural inspections, office space, and holding cells for passengers who are prohibited from entering the U.S. or who are being detained and transported by law enforcement. Phase two of the project will renovate the remainder of the building to create an international terminal or Federal Inspection Service, should the airport establish nonstop international charter flights. Gere-Dismer Architects of Rock Island designed the facility.
