Narrative:

I was working local control with moderate traffic when I cleared small aircraft to land runway 18. As I was scanning the runways, I noticed a red van, mo plates XXXX, coming from the north T hangars. The va turned onto taxiway C and accelerated to a moderate speed going toward runway 18 threshold. I immediately told ground that he had a veh going toward my runway. Ground responded that he didn't know who it was. With small aircraft on short final, I gave him a go around due to an unauthorized veh on his runway. The van apparently heard the aircraft throttling up to go around and stopped suddenly at the edge of the runway. The van then turned around and left the airport via an open gate by the GA terminal. An airport veh was able to get the van's license plate # as it was leaving the airport. To remedy this situation the airport needs to install limited access gates using cards or codes to enter the airport ramp areas.
