Narrative:

Uga X, BE36, at 4000 ft en route to altitude was vectored 10 degree left for departures off wrb. Air carrier Y, E120, was released off mln runway 13 and given runway heading on the climb out. On initial contact, with the E120 I climbed him to 10000 ft after xmissions with other aircraft, the conflict alert sounded and I gave air carrier Y a turn to 180 degree immediately to miss the BE36? The crew of air carrier Y reported the BE36 in sight and I told them to maintain visual separation. I then issued traffic to ugax. Air carrier Y passed off the rear of ugax.

Narrative: UGA X, BE36, AT 4000 FT ENRTE TO ALT WAS VECTORED 10 DEG L FOR DEPS OFF WRB. ACR Y, E120, WAS RELEASED OFF MLN RWY 13 AND GIVEN RWY HDG ON THE CLBOUT. ON INITIAL CONTACT, WITH THE E120 I CLBED HIM TO 10000 FT AFTER XMISSIONS WITH OTHER ACFT, THE CONFLICT ALERT SOUNDED AND I GAVE ACR Y A TURN TO 180 DEG IMMEDIATELY TO MISS THE BE36? THE CREW OF ACR Y RPTED THE BE36 IN SIGHT AND I TOLD THEM TO MAINTAIN VISUAL SEPARATION. I THEN ISSUED TFC TO UGAX. ACR Y PASSED OFF THE REAR OF UGAX.
