I was working final at N90 JFK area. An A340 on final for Runway 31R on an ILS approach and an A319 was vectored for a visual approach to Runway 31L. The A319 was issued traffic about the A340. The A319 advised the A340 was in sight. I said 'maintain visual separation.' At some point I also cleared the A319 for a Visual Approach to Runway 31L. I am not sure of exact times. Replay on the operations floor has no audio replay. I was advised of a 'wake remnant separation event on final' today. I have never been advised what 'wake remnant' is or how to identify it or how to avoid/separate from it. There is a program called 'falcon' that seems to have a wake turbulence 'cookie' or 'hoop' that may display some sort area to avoid. Why is this not on the ARTS display that we use? How can we be held responsible for something the FAA has not identified to me; the 7110.65 has no mention of; the FAA can't tell me how to avoid or separate from. QA people are identifying controllers for 'events' on this matter.
N90 Controller voiced concern regarding a loss of 'wake remnant' separation determination made by the QA office; the reporter noted current Orders do not cover this anomaly and ATC equipment can not identify same.
