TRACON departure controller received coordination from tower local controller that an air carrier commuter is executing a go around from lax runway 6L with the simultaneous departure of an A320 off runway 6R. Tower advises the commuter will turn heading 040 degrees. The TRACON controller turned the A320 right 070 degrees, but the targets merged. Both pilots report TCASII alerts. Reporter contributes lack of operational radar currency as a factor.

Narrative:
While working dr-2 air carrier commuter went around on runway 6L due to WX. An air carrier jet on departure runway 6R was airborne at the same time. I turned the air carrier jet immediately to a 070 degree heading to avoid the commuter. Lax tower advised me that the commuter would be on a 040 degree heading. Both pilots reported a TCASII alert. No separation existed. Targets seemed to merge at the same altitude. Most importantly, 16 hours of time per month is required to stay current. Several fpl's at sct in the la area don't have this and are required to work.

Title: TRACON DEP CTLR RECEIVED COORD FROM TWR LCL CTLR THAT AN ACR COMMUTER IS EXECUTING A GAR FROM LAX RWY 6L WITH THE SIMULTANEOUS DEP OF AN A320 OFF RWY 6R. TWR ADVISES THE COMMUTER WILL TURN HDG 040 DEGS. THE TRACON CTLR TURNED THE A320 R 070 DEGS, BUT THE TARGETS MERGED. BOTH PLTS RPT TCASII ALERTS. RPTR CONTRIBUTES LACK OF OPERATIONAL RADAR CURRENCY AS A FACTOR.
