Narrative:

The departure controller called and requested an arrival gap for the release of an IFR runway 19 departure from teterboro. I gave him a gap between aircraft Y and aircraft Z. At the time there was a natural gap of almost 10 miles or more between these 2 arrivals. To the best of my knowledge departure advised teb of the aircraft they could release their departure behind. This is SOP. I maintained the gap between the 2 aircraft but I forgot I had released the departure. As I turned aircraft Z for his approach and cleared him; the departure came airborne. The departure controller yelled down he was stopping his aircraft at 2000 feet. At that point I realized I had forgotten the departure and that teb had missed the gap. I cancelled the approach clearance for aircraft Z and I turned him right. As he turned I knew I would not have enough space to hold separation with the departure so I turned him further to the right and called traffic. They did not have the aircraft in sight. Departure then advised me he had visual on my traffic and was commencing a climb. I continued the aircraft Z in a right turn; re-established him on the approach and he landed without incident. I am not sure there is a recommendation to be made. Teb was late getting their departure airborne because of traffic in their pattern. I forgot the departure as I allowed myself to lose focus because traffic was light. Vigilance must be maintained at all times; 1 airplane or 40.

Title: A TRACON Controller reported about forgetting to approving a satellite airport departure and the departure was released late causing a loss of separation between the two aircraft.

Narrative: The Departure Controller called and requested an arrival gap for the release of an IFR Runway 19 Departure from Teterboro. I gave him a gap between Aircraft Y and Aircraft Z. At the time there was a natural gap of almost 10 miles or more between these 2 arrivals. To the best of my knowledge departure advised TEB of the aircraft they could release their departure behind. This is SOP. I maintained the gap between the 2 aircraft but I forgot I had released the departure. As I turned Aircraft Z for his approach and cleared him; the departure came airborne. The departure controller yelled down he was stopping his aircraft at 2000 feet. At that point I realized I had forgotten the departure and that TEB had missed the gap.
