You have to meet NPA-28 (if memory serves - don't have my files at home) - it was known as NPA-SAL. The main thing is, apart from demonstrating correct operations on the approach you want, you have to show that you can do an approach 2 degrees steeper without the throttles going to idle - not easy in a jet.
I know someone who was on the dash-8 400 LCY cert and they used a private airfield in eastern California that allowed them to set up not only the normal 5.5 degrees but also the 7.5 required.
They also then had to go and do it for real at LCY. He said a big problem for them was the length of their aircraft & manouvering around at City - apparently there's not a lot of apron space.
