Procedure
Aircraft X was on approach to Runway 22L; Aircraft Z was cleared for takeoff on Runway 22R from intersection Whiskey. I side stepped Aircraft X to Runway 22R because a heavy jet was in trail and gaining on Aircraft X. Aircraft Y was rolling out on Runway 22L and turned off at November. I first instructed Aircraft Y to hold short of Runway 22R then scanned the radar and observed that Aircraft X was still on a 2 mile final and I had time to get Aircraft Y across Runway 22R before Aircraft X landed. I forgot about Aircraft Z and did not pick him up on my visual scan when I went to look for Aircraft X. The cab coordinator advised me that Aircraft Z was rolling and I instructed Aircraft Y to hold short of Runway 22R; visual observation indicated that Aircraft Y would not be able to stop in time. I then canceled takeoff clearance on Aircraft Z and sent Aircraft X around. The ASDE-X alerted after the takeoff Aircraft Z stopped at the intersection of Taxiway Golf. The strip movement and placement were in accordance with the SOP; I forgot about Aircraft Z. The aircraft must have been between two windows and was blocked out by the mullion between the windows. I need to move around when I scan which would allow me to pick up situations hidden behind the mullions when doing a visual scan.
Landed 22L and exited at November high-speed. Approaching the crossing for 22R on November; ATC instructed us to cross 22R without delay; hold short PA; and in the middle of this transmission; instructed us to stop and hold position. We stopped after crossing the hold short line; but were still clear of the runway. Another aircraft that had been given a takeoff clearance for 22R was told to cancel takeoff clearance. They did abort their takeoff. Another aircraft was on final for 22R and was told to go-around.We followed ATC instructions without realizing the aircraft on 22R had been given a takeoff clearance.
EWR Controller reports of a situation where he forgets about an aircraft that is departing while he tells a landing aircraft to cross the departures runway while another aircraft is on final. Controller aborts the departure; sends the arrival around; because crossing traffic has passed the hold short bars.
