SEPARATION LOST BTWN AN E120 AND A CRJ WHEN S56 HANDED OFF #2 CRJ ACFT FIRST WITHOUT INSURING SEPARATION FROM #1 E120 ACFT.

Narrative

ACFT X (E120) WAS AT 12000 FT; SBOUND FROM SLC. ACFT Y WAS ALSO SBOUND FROM SLC CLBING ABOVE ACFT X. I NEGLECTED TO CLB ACFT Y TO 16000 FT AS PER ZLC LOA. I HAD ONLY CLBED THE ACFT TO AN INTERIM ALT OF 14000 FT. 5 OTHER JETS TOOK OFF FROM SLC; ALL OF THEM SBOUND AND ALL CLBING ABOVE ACFT X. THE DEP RTE OF ALL THESE ACFT WAS DIRECT FFU FROM SLC (IN A STRAIGHT LINE). I TOLD ACFT Y TO CONTACT ZLC WHEN OUT OF 13800 FT (THINKING HE WOULD CONTINUE TO CLB TO 16000 FT). WX WAS BAD; FRONT MOVING IN AND MODERATE TURB. I CLBED THE E120 TO 14000 FT. I NOTICED THAT THE CRJ2 WAS STILL LEVEL 14000 FT; BUT BEHIND; AND 5 MI OFFSET AND DIVERGING. I THOUGHT THAT ZLC HAD TURNED THE CRJ2 (ACFT Y) DIRECT AND CALLED THEM TO SEE IF I HAD FORGOTTEN TO CLB ACFT Y TO 16000 FT. THEY SAID I HAD AND WOULD 'BUMP HIM UP.' AS IT TURNS OUT; I HAD ALSO NOT ASSIGNED ACFT Y THE STAR; AND THE ACFT WAS ON THE 160 DEG HDG ASSIGNED BY TWR. THE WIND HAD BLOWN ACFT Y TO THE E; 5 MI OFF THE TRACK OF ACFT X. ZLC TURNED ACFT Y BACK ONTO THE DEP PROC; AND THE ACFT TURNED TOWARD ACFT X. WHEN I SAW THE CRJ2 TURNING TOWARD ACFT X; STILL AT 14000 FT AND RAPIDLY OVERTAKING; I ISSUED ACFT X A 20 DEG R TURN AND AN IMMEDIATE DSCNT TO 13000 FT. SEPARATION WAS LOST; CLOSEST PROX WAS 500 FT AND 2.66 MI. MY FAILURE TO PUT ACFT Y ON COURSE AT THE PROPER ALT CAUSED THE ABOVE ERROR. I THOUGHT ZLC HAD TURNED ACFT Y DIRECT TO HIS DEST; WHEN IN FACT; THE WIND HAD CAUSED THE CRJ2 TO DIVERGE FROM ACFT X. I WAS NOT TOLD THAT ACFT Y WAS CORRECTING BACK INTO THE PATH OF ACFT X NOR DID ZLC KNOW THAT I WAS CLBING ACFT X TO 14000 FT.
