Narrative:

The problem arose due to the fact the WW23 departed lzu airport on a 310 degree heading at 3000 ft MSL and did not automatic acquire on the ARTS. Contributing factors included a radar position that was so busy I could not mark or look at my flight progress strips. My handoff controller was releasing departures which I knew nothing about. I also had 2 aircraft at 5000 ft, 5 NM apart on converging course. I was talking to one, but not the other. Discovery was the C550 asked about the traffic at his altitude. All departures should be in the ARTS tab list before being released. No aircraft should be released by the handoff without the radar controller's knowledge.

Title: A80 APCH CTLR EXPERIENCES LOSS OF SEPARATION WHEN HDOF CTLR RELEASES IFR DEP FROM ADJACENT ARPT WITHOUT COORD OR CONFIRMATION OF RADAR CTLR.

Narrative: THE PROB AROSE DUE TO THE FACT THE WW23 DEPARTED LZU ARPT ON A 310 DEG HDG AT 3000 FT MSL AND DID NOT AUTO ACQUIRE ON THE ARTS. CONTRIBUTING FACTORS INCLUDED A RADAR POS THAT WAS SO BUSY I COULD NOT MARK OR LOOK AT MY FLT PROGRESS STRIPS. MY HDOF CTLR WAS RELEASING DEPS WHICH I KNEW NOTHING ABOUT. I ALSO HAD 2 ACFT AT 5000 FT, 5 NM APART ON CONVERGING COURSE. I WAS TALKING TO ONE, BUT NOT THE OTHER. DISCOVERY WAS THE C550 ASKED ABOUT THE TFC AT HIS ALT. ALL DEPS SHOULD BE IN THE ARTS TAB LIST BEFORE BEING RELEASED. NO ACFT SHOULD BE RELEASED BY THE HDOF WITHOUT THE RADAR CTLR'S KNOWLEDGE.
