Narrative:

I was on duty as the local controller at csg. I was advised that small aircraft X would be on an ASR surveillance radar approach to 4WY 23, as well as which position (ARDR2) and frequency (126.0) would be used for the approach. I selected the receiver for 126.0 so I could monitor the aircraft on final. I expected to have the frequency released to me on short final. When the aircraft was on less than 1 mi final and indicating 700 MSL (300 AGL), the surveillance controller advised him to take over visually and contact ground control (121.9) clearing the runway. (Ground control was combined with local control and was thus also my responsibility.) the surveillance controller then released 126.0 (the surveillance frequency) to another approach controller who immediately selected it and started to transmit on it along with his other frequencys. This caused: 1) pilot to have to note the ground control frequency while on short final. 2) no immediate communication availability on short final since another approach controller was actively using the frequency. Also no communication while on the runway until after he turned off the runway and switched frequencys. Problem: neither the local procedure nor handbook 7110.65E chapter 5 provide any guidance on frequency changes for aircraft on ASR apches.

Title: ACFT ON ASR APCH WAS ADVISED TO CONTACT GND CTL AFTER LNDG INSTEAD OF LCL CTL.

Narrative: I WAS ON DUTY AS THE LCL CTLR AT CSG. I WAS ADVISED THAT SMA X WOULD BE ON AN ASR SURVEILLANCE RADAR APCH TO 4WY 23, AS WELL AS WHICH POSITION (ARDR2) AND FREQ (126.0) WOULD BE USED FOR THE APCH. I SELECTED THE RECEIVER FOR 126.0 SO I COULD MONITOR THE ACFT ON FINAL. I EXPECTED TO HAVE THE FREQ RELEASED TO ME ON SHORT FINAL. WHEN THE ACFT WAS ON LESS THAN 1 MI FINAL AND INDICATING 700 MSL (300 AGL), THE SURVEILLANCE CTLR ADVISED HIM TO TAKE OVER VISUALLY AND CONTACT GND CTL (121.9) CLEARING THE RWY. (GC WAS COMBINED WITH LC AND WAS THUS ALSO MY RESPONSIBILITY.) THE SURVEILLANCE CTLR THEN RELEASED 126.0 (THE SURVEILLANCE FREQ) TO ANOTHER APCH CTLR WHO IMMEDIATELY SELECTED IT AND STARTED TO XMIT ON IT ALONG WITH HIS OTHER FREQS. THIS CAUSED: 1) PLT TO HAVE TO NOTE THE GC FREQ WHILE ON SHORT FINAL. 2) NO IMMEDIATE COM AVAILABILITY ON SHORT FINAL SINCE ANOTHER APCH CTLR WAS ACTIVELY USING THE FREQ. ALSO NO COM WHILE ON THE RWY UNTIL AFTER HE TURNED OFF THE RWY AND SWITCHED FREQS. PROBLEM: NEITHER THE LCL PROC NOR HANDBOOK 7110.65E CHAPTER 5 PROVIDE ANY GUIDANCE ON FREQ CHANGES FOR ACFT ON ASR APCHES.
