I appreciate the input, any required licensing and other administrative stuff is WAY down the road from where I'm currently at. This was simply me inquiring as to the possibility of interference. We have tanks that range from 30' to over 160' in elevation. Last year we had someone put a bullet hole (unfortunately, not a one off occurrence) in one of the larger ones (elevation wise) and had some difficulty in reaching the particular location for inspection purposes (the welding company is quite a distance away and had requested photos of the damage if possible prior to their mobilizing equipment for repairs. I and some of my employees had just started thinking that this might be something that I could have at least got a quick and dirty look at the issue to develop a plan.
We do have a regular inspection program in place for our tanks. This was just something that we had thought about at that moment in time and tried to think of potential technical limitations and though I'd ask you good folks for information...I didn't mean to cause a stir.
