Narrative:

Aircraft X (E120) was at 12000 ft, sbound from slc. Aircraft Y was also sbound from slc climbing above aircraft X. I neglected to climb aircraft Y to 16000 ft as per ZLC LOA. I had only climbed the aircraft to an interim altitude of 14000 ft. 5 other jets took off from slc, all of them sbound and all climbing above aircraft X. The departure route of all these aircraft was direct ffu from slc (in a straight line). I told aircraft Y to contact ZLC when out of 13800 ft (thinking he would continue to climb to 16000 ft). WX was bad, front moving in and moderate turbulence. I climbed 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 (aircraft Y) direct and called them to see if I had forgotten to climb aircraft Y to 16000 ft. They said I had and would 'bump him up.' as it turns out, I had also not assigned aircraft Y the STAR, and the aircraft was on the 160 degree heading assigned by tower. The wind had blown aircraft Y to the east, 5 mi off the track of aircraft X. ZLC turned aircraft Y back onto the departure procedure, and the aircraft turned toward aircraft X. When I saw the CRJ2 turning toward aircraft X, still at 14000 ft and rapidly overtaking, I issued aircraft X a 20 degree right turn and an immediate descent to 13000 ft. Separation was lost, closest proximity was 500 ft and 2.66 mi. My failure to put aircraft Y on course at the proper altitude caused the above error. I thought ZLC had turned aircraft Y direct to his destination, when in fact, the wind had caused the CRJ2 to diverge from aircraft X. I was not told that aircraft Y was correcting back into the path of aircraft X nor did ZLC know that I was climbing aircraft X to 14000 ft.

Title: 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.
