Narrative:

I had an aircraft that was in the run up area for runway 17L that called ready for departure. I told the aircraft 'runway 17L taxi via alpha one and then monitor tower.' the aircraft did not read back the runway assignment. I told the local controller that the pilot did not read back the runway assignment. The local controller said that he did not hear me pass that information to him. The aircraft went onto the runway without clearance. I am being told it is my fault. Recommendation; I recommend that we taxi all aircraft to the runway like every other airport does and like the FAA 7110.65 says we can. Instead we have a procedure that we taxi all aircraft that need a run up to the run up area; then taxi them to the runway. The problem is that pilots don't understand that they are not at the runway when they are in the run up area because the run up area is at the end of the runway. Pilots are constantly confused with the taxi procedures here and often make mistakes like this.
