D21 CTLR EXPERIENCED OPERROR AT 3000 FT WHEN HE OR SHE INCORRECTLY ASSUMED DEP RWY INFO AND ISSUED A CONFLICTING TURN.

Narrative

I WAS WORKING THE 'CRUXX' RADAR SECTOR OPERATING WILLOW RUN (YIP) DEPS; DETROIT METRO (DTW) PROP DEPS; LOW ALT ARRS; AND LOW ALT ENRTE TFC. YIP DEP PROCS REQUIRE A DATA STRIP WITH THE RWY OF DEP PRINTED ON IT AND AN AUTO FLASH RELEASE FEATURE DISPLAYED ON THE RADAR SCREEN. YIP ACTIVE RWY WAS RWY 23L. I RELEASED THE FIRST DEP; ACR X; OFF RWY 23L WITH AN IFR CLRNC FROM YIP TO PTK (PONTIAC INTL); APPROX 15 MI N OF YIP. I RADAR IDENTED ACR X OFF RWY 23L; ASSIGNED AN ALT OF 3000 FT; AND ISSUED A TURN TO 270 DEGS. AT THIS MOMENT I RELEASED ACR Y TO DEPART YIP. I ASSUMED THEY WERE ALSO DEPARTING RWY 23L EVEN THOUGH THE FLT PROGRESS STRIP SHOWED RWY 27. NO OTHER COORD IS NECESSARY FOR A DEP COMING OFF A RWY OTHER THAN THE ACTIVE. I TURNED ACR X TO A 030 DEG HDG AND ADVISED THEM TO PROCEED TO PTK WHEN ABLE. I WAS STILL THINKING ACR Y WAS COMING OFF RWY 23L AND ACR X WAS WELL W OFF THE DEP PATH. AT THIS SAME TIME I HAD A VISUAL APCH INTO A SATELLITE ARPT JUST INSIDE ANOTHER CTLR'S AIRSPACE THAT CANCELLED HIS IFR FLT PLAN. I HAD COORDINATED WITH THE OTHER CTLR AND ADVISED THEM OF THE CANCELLATION. TOLEDO APCH CALLED WITH A POINTOUT TO THE S OF MY AIRSPACE. I HAD NO COORDINATOR; SO I ANSWERED THE LINE AND RECEIVED NOT ONE; BUT 2 POINTS; ONE FROM ANOTHER SECTOR IN TOLEDO APCH. I ALSO RECEIVED COORD FROM A DTW JET DEP CTLR WITH APPROVAL TO CLB ANOTHER ACFT. THEN ACR Y CALLED AIRBORNE OFF RWY 27 LEVEL AT 3000 FT AND TURNING TO A 300 DEG HDG AS ASSIGNED BY YIP TWR. I RADAR IDENTED ACR Y AND ISSUED AN IMMEDIATE TURN TO 360 DEGS; AND ISSUED A TURN TO 300 DEGS TO ACR X TO OBTAIN DIVERGING HDGS. I WAS UNDER THE ASSUMPTION BOTH ACFT WERE DEPARTING THE SAME ACTIVE RWY. EVEN THOUGH I HAD PRIOR KNOWLEDGE WRITTEN ON THE FLT PROGRESS STRIP AND WITH THE AUTOMATED RELEASE FUNCTION ON MY RADAR SCREEN IT ALSO SHOWED RWY 27 IN SMALL LETTERING AT THE END OF THE CALL SIGN. I AM NOT PLACING BLAME ELSEWHERE. I SHOULD HAVE KNOWN THE DEP RWY OF THE SECOND ACFT AND NOT RELEASED THEM. I DO NOT FEEL THAT THIS PROC COULD BE IMPROVED. A SIMPLE COORD CALL BY YIP TWR TELLING ME THAT ACR Y WAS A RWY 27 DEP AND THIS SCENARIO WOULD HAVE NEVER HAPPENED.
