Narrative:

Leaving the general aviation ramp with taxi clearance as follows: taxi down runway 31 to taxiway right, hold short of runway 30R. After clearing runway 31 onto taxiway right, a hold short line came into view. I felt that this line was for runway 31 as had I stopped before the line it would have put the aircraft tail too close to runway 31. There was no NOTAM stating that runway 31 was closed, thus I could only assume it was open. So I crossed this line looking ahead for the hold short line that applied to my taxi clearance. Moving ahead a short distance and not seeing another line I stopped my taxi immediately to prevent entering onto runway 30R. After arriving back at my home base, during a telephone conversation with stl tower supervisor. He confirmed to me that they have a real problem with people not holding short in this area. I believe better markings or signage in this area is paramount to preventing this type of occurrence. Callback conversation with reporter revealed the following information: reporter could not recall if the hold line he saw was broken or solid. He said the C-550 is approximately 55 ft long and he was concerned that his tail was out on runway 31.
