Narrative:

While working departure radar east I had an aircraft filed out through rfd at 6000'. I handed the act off to the the arrival controller who subsequently rerted the aircraft V18, V37, moped, bzm, hmv, rfd, at 8000'. I had an aircraft southbound at 8000' on V37. The ARTS III a collision alert went off alerting us that the aircraft were on converging courses. At that point we took action to ensure that the aircraft were separated as required by the 7110.65. Sep never deteriorated below on east mi. I believe contributing factors to the incident were workload, which prevented me from doing the required coordination with the arrival controller.

Title: IFR SMA WAS CLIMBED TO AN OCCUPIED ALT RESULTING IN LESS THAN STANDARD SEPARATION WITH AN ACFT ON CONVERGING COURSE.

Narrative: WHILE WORKING DEP RADAR E I HAD AN ACFT FILED OUT THROUGH RFD AT 6000'. I HANDED THE ACT OFF TO THE THE ARR CTLR WHO SUBSEQUENTLY RERTED THE ACFT V18, V37, MOPED, BZM, HMV, RFD, AT 8000'. I HAD AN ACFT SBND AT 8000' ON V37. THE ARTS III A COLLISION ALERT WENT OFF ALERTING US THAT THE ACFT WERE ON CONVERGING COURSES. AT THAT POINT WE TOOK ACTION TO ENSURE THAT THE ACFT WERE SEPARATED AS REQUIRED BY THE 7110.65. SEP NEVER DETERIORATED BELOW ON E MI. I BELIEVE CONTRIBUTING FACTORS TO THE INCIDENT WERE WORKLOAD, WHICH PREVENTED ME FROM DOING THE REQUIRED COORD WITH THE ARR CTLR.
