Narrative:
A H/B767/right is on final with N90 followed by a T/B757/right 4 1/2 mi intrail and faster. So no separation is being used and it goes down to less than 4 mi by the time they switch to ewr tower you need 5 mi and every day we get less than 5 mi behind heavies. During my session I had to cancel approach clrncs to at least 3 other aircraft. We have met with N90 in the past and their answer to lack of separation behind heavies is send them around. This punishes the airlines for N90 lack of controling abilities.
