Narrative:
Air carrier X on radar vector after climb out from iad heading 130 degree, received TA on TCASII. Aircraft Y in view. Given climb to 15000 ft and heading to 150 by washington approach control. 'RA' alert received on TCASII indicated a min climb of 500 FPM. In my opinion best course of action was to level off as target aircraft Y was climbing rapidly and would pass above and to the left. Told by new york center to contact washington approach control after landing. I was told by supervisor that approach control had taken us 5 mi into bwi departure airspace. In my opinion this was not a near miss and no unusual control inputs were required.
