Narrative:
Aircraft X; PA31; departed runway 32R on a 320 degree heading to avoid a course crossover with air carrier Y; a B727; departing runway 36 on a 360 degree heading. I instructed the B727 to contact departure first; before I would turn the PA31 on a 020 degree heading. Air carrier Y was heading to memphis; tn; and aircraft X to davenport; ia. I observed air carrier Y turning eastbound; and once separation was ensured; I instructed aircraft X to turn to an assigned heading of 020 degrees. In accordance with the LOA between omaha tower and omaha approach control; the departure controller is to turn the aircraft on course at the earliest opportunity; reference prior departures. There were no prior eastbound departures coming off behind air carrier Y. The east departure controller was aware of the pending situation; but only took action at the least opportune time. I have handled this type of situation on many different occasions with no previous problems. In the future; in-trail separation will be utilized.

Title: OMA LCL CTLR EXPERIENCED OPERROR WITH 2 DEPS WHEN EXPECTED ACTIONS BY THE TRACON WERE NOT TAKEN IN A TIMELY MANNER.
Narrative: ACFT X; PA31; DEPARTED RWY 32R ON A 320 DEG HDG TO AVOID A COURSE CROSSOVER WITH ACR Y; A B727; DEPARTING RWY 36 ON A 360 DEG HDG. I INSTRUCTED THE B727 TO CONTACT DEP FIRST; BEFORE I WOULD TURN THE PA31 ON A 020 DEG HDG. ACR Y WAS HEADING TO MEMPHIS; TN; AND ACFT X TO DAVENPORT; IA. I OBSERVED ACR Y TURNING EBOUND; AND ONCE SEPARATION WAS ENSURED; I INSTRUCTED ACFT X TO TURN TO AN ASSIGNED HDG OF 020 DEGS. IN ACCORDANCE WITH THE LOA BTWN OMAHA TWR AND OMAHA APCH CTL; THE DEP CTLR IS TO TURN THE ACFT ON COURSE AT THE EARLIEST OPPORTUNITY; REF PRIOR DEPS. THERE WERE NO PRIOR EBOUND DEPS COMING OFF BEHIND ACR Y. THE E DEP CTLR WAS AWARE OF THE PENDING SITUATION; BUT ONLY TOOK ACTION AT THE LEAST OPPORTUNE TIME. I HAVE HANDLED THIS TYPE OF SITUATION ON MANY DIFFERENT OCCASIONS WITH NO PREVIOUS PROBS. IN THE FUTURE; IN-TRAIL SEPARATION WILL BE UTILIZED.
