Narrative:
I was working the 'right' position at the valley (30) sector. I had an small aircraft (GA) aircraft to call for clearance from the falwell airport. I gave clearance to small aircraft X. The manual controller cleaned an air taxi (small transport Y) off the ground on runway 3 at lyh. I wasn't aware that he did so, even though he said he told me. I never acknowledged any information like this. I first realized there was a problem when the small transport Y called. I issued a turn and stopped the climb. I accept the blame for this only because I was in charge of the sector.

Narrative: I WAS WORKING THE 'R' POS AT THE VALLEY (30) SECTOR. I HAD AN SMA (GA) ACFT TO CALL FOR CLRNC FROM THE FALWELL ARPT. I GAVE CLRNC TO SMA X. THE MANUAL CTLR CLEANED AN AIR TAXI (SMT Y) OFF THE GND ON RWY 3 AT LYH. I WASN'T AWARE THAT HE DID SO, EVEN THOUGH HE SAID HE TOLD ME. I NEVER ACKNOWLEDGED ANY INFO LIKE THIS. I FIRST REALIZED THERE WAS A PROBLEM WHEN THE SMT Y CALLED. I ISSUED A TURN AND STOPPED THE CLB. I ACCEPT THE BLAME FOR THIS ONLY BECAUSE I WAS IN CHARGE OF THE SECTOR.
