Descend at least 1500fpm on an unrestricted decent of more than 1000ft. If you don't maintain at least that you could mess up the controllers planning and create a conflict.
Doesn't apply if you have crossing restrictions, as long as you make them.
Is the 1500fpm descent in the AIM or something? I always descend 1000fpm if I haven't reached TOD. Never heard a word from ATC.
