Narrative:

I was working mead departure (med) confign 3; I heard someone yell aircraft X is going around looked at the airport and saw aircraft X and the arrival to runway 1 mode C 100 ft apart can't remember if conflict alert activated then tower flashed aircraft X to me at med. I called tower and said it was daggatt departure's airspace and that aircraft X should go to dag. This was about 2 mi west of departure end of runway 25L. Aircraft X went missed from runway 25L. I am 90% sure aircraft X entered the 6000 ft MOA west of las at 5000 ft. I had traffic in my airspace and was busy with WX deviations. I could hear dag yelling in the background that they are not talking to aircraft X; he was not on my frequency. Supplemental information from acn 696345: both aircraft #1 and #2 went around due to windshear. According to SOP the aircraft were assigned 5000 ft; even though the MOA 6 NM west of las is 6000 ft the departure controller did not have radio contact with either aircraft before they entered the 6000 ft MVA. This event was totally caused by a poor procedure and resulted in at least these 2 aircraft to be assigned an altitude below the MVA. Additionally; las tower was unsure who to hand off the aircraft to and who to frequency change them to even though they were advised by the L30 supervisor. Management was aware of and advised of the situation but as far as I know no corrective actions have occurred.

Title: L30 CTLRS DESCRIBE CONFLICT AS LR45 LNDG RWY 25L AND ACR LNDG RWY 1 BOTH EXECUTE GAR DUE TO WINDSHEAR; GAR PROCS CONFUSING; WITH ACFT ENDING UP BELOW MVA ALTS.

Narrative: I WAS WORKING MEAD DEP (MED) CONFIGN 3; I HEARD SOMEONE YELL ACFT X IS GOING AROUND LOOKED AT THE ARPT AND SAW ACFT X AND THE ARR TO RWY 1 MODE C 100 FT APART CAN'T REMEMBER IF CONFLICT ALERT ACTIVATED THEN TWR FLASHED ACFT X TO ME AT MED. I CALLED TWR AND SAID IT WAS DAGGATT DEP'S AIRSPACE AND THAT ACFT X SHOULD GO TO DAG. THIS WAS ABOUT 2 MI W OF DEP END OF RWY 25L. ACFT X WENT MISSED FROM RWY 25L. I AM 90% SURE ACFT X ENTERED THE 6000 FT MOA W OF LAS AT 5000 FT. I HAD TFC IN MY AIRSPACE AND WAS BUSY WITH WX DEVS. I COULD HEAR DAG YELLING IN THE BACKGROUND THAT THEY ARE NOT TALKING TO ACFT X; HE WAS NOT ON MY FREQ. SUPPLEMENTAL INFO FROM ACN 696345: BOTH ACFT #1 AND #2 WENT AROUND DUE TO WINDSHEAR. ACCORDING TO SOP THE ACFT WERE ASSIGNED 5000 FT; EVEN THOUGH THE MOA 6 NM W OF LAS IS 6000 FT THE DEP CTLR DID NOT HAVE RADIO CONTACT WITH EITHER ACFT BEFORE THEY ENTERED THE 6000 FT MVA. THIS EVENT WAS TOTALLY CAUSED BY A POOR PROC AND RESULTED IN AT LEAST THESE 2 ACFT TO BE ASSIGNED AN ALT BELOW THE MVA. ADDITIONALLY; LAS TWR WAS UNSURE WHO TO HAND OFF THE ACFT TO AND WHO TO FREQ CHANGE THEM TO EVEN THOUGH THEY WERE ADVISED BY THE L30 SUPVR. MGMNT WAS AWARE OF AND ADVISED OF THE SITUATION BUT AS FAR AS I KNOW NO CORRECTIVE ACTIONS HAVE OCCURRED.
