Narrative:

Small transport was being vectored for an opp direction approach to runway 36R. Light transport was cleared for takeoff runway 18L. I was working approach control and vectoring small transport for a visibility approach to runway 36R, after coordinating with the tower. I observed the departure and anticipating a loss of sep, turned small transport right to 090 degrees. In the meantime the tower turned light transport to 090 degrees. Sep was lost with minimum sep being 500' and 0.88 mi. If opp direction operations are not used then this type of occurrence could not happen. The aircraft were on separate frequencys. When opp direction operations are used you must coordinate and be aware of the other traffic's position at all times.

Original NASA ASRS Text

Title: SEPARATION WAS LOST BETWEEN A DEPARTING ACFT AND AN OPPOSITE DIRECTION ARRIVING ACFT.

Narrative: SMT WAS BEING VECTORED FOR AN OPP DIRECTION APCH TO RWY 36R. LTT WAS CLRED FOR TKOF RWY 18L. I WAS WORKING APCH CTL AND VECTORING SMT FOR A VIS APCH TO RWY 36R, AFTER COORDINATING WITH THE TWR. I OBSERVED THE DEP AND ANTICIPATING A LOSS OF SEP, TURNED SMT RIGHT TO 090 DEGS. IN THE MEANTIME THE TWR TURNED LTT TO 090 DEGS. SEP WAS LOST WITH MINIMUM SEP BEING 500' AND 0.88 MI. IF OPP DIRECTION OPS ARE NOT USED THEN THIS TYPE OF OCCURRENCE COULD NOT HAPPEN. THE ACFT WERE ON SEPARATE FREQS. WHEN OPP DIRECTION OPS ARE USED YOU MUST COORDINATE AND BE AWARE OF THE OTHER TFC'S POS AT ALL TIMES.
