The Customs C31 center program will enable it to integrate multiple sensor and other data sources into centralized facilities to improve the detection and interception of suspected drug smugglers and to enhance antismuggling intelligence. The Customs Service plans to establish eastern and western sector centers as well as a national command center. The C31 program primarily supports air interdiction, although the eastern sector will include marine interdiction activities. Contracts have been awarded for the first phase of the centers' establishment. The Coast Guard has been involved in the design and location of the centers. Customs has also kept other agencies informed about its plans and has asked for the help of the Department of Defense. Issues that need to be decided are whether to locate the command structure at the Richmond Heights, Fla., C31 center; whether a national C31 center will be located in Oklahoma City; and the cost of the program.
