If you are talking about Sewark, I don't think we go as low as 3000' around the Solberg area, we usually get 3000' just prior to intercepting the localizer, either for 04R or 22L (unless the controllers dump you at 2500' after passing TEB for 22L). BTW about 2 years ago we almost ran into a glider coming in around Crank/SAX, we missed him by about 2-300 feet as he dove out of our way. He would have lost as we were in a 767-400. I better not complain though as I fly sailplanes on my few off days...
