I would imagine that the obstruction is in the approach plate so the pilot should know that it is there. Also, by saying cross the IAF at or above 2300 means the pilot can stay at 3000 if they want to. What if you cleared him by saying "Maintain 3000 until established on the final approach course, cleared RNAV 36 approach". That seems like it would cover your bases as well. I'm curious to hear what others think though, I can't say I know 100% if what I said is right.
