      Josh, that fits right in with my KABLAMO thread from this morning.

      If that 18" gas main had been hit by the vehicle that hit the pole, it would have been the same result, except it would have been a church and a couple houses that would be missing.

        Amazing and....sad.

        I want to know where the markers are stating the line is there? Where's the signs? Some burned maybe, but the further out ones should be there.

        Someone I know has the same type line crossing their property and it is fenced by the owner (Cardinal Pipeline) on both sides of the line and warning marked I estimate every 100'.

        The person may have had no idea to call for location before he/she began work.

                Twenty years ago or so we had a problem in a large apartment complex and did a locate of the sewer. I called out dig-alert who came out and marked the Utilities. Because the ares was under a carport we had to dig it by hand. My guys broke out the concrete and got down about 30" and ran into some steel. They thought it may have been something which had been abandoned from when the area was an active oil field but they called me anyways. I told them to stop digging until I got there.

                When I got there we removed a little more dirt and noticed it appeared to be a big pipe. I stopped and found a Gas Company crew which was working down the street. To my surprise they came over and identified it as a 24" high-pressure gas line serving the San Joaquin Valley. He said they thought it was 100 yards or so to the south and were glad to find it. The scary part is dig-alert never looked for it because the map showed it elsewhere. It is now correctly mapped but still under the carport.

                  was working for some shmuk many years ago. W had a job to build a guard shack at a bank out in the parking lot in Cambridge, MA code here says 4 foot foundation for a 5' x 5' guard shack.

                  Anyway he said he had called dig safe and all that so we started digging 3 feet down or so i ran into a yellow jacketed Gas pipe 2 or 3 inch i don't remember now.

                  Called the "boss" (this guy was an idiot) he said its nothing and to cut it out HA i said no way and that hes crazy and that he didn't know his A$$ from his elbow.

                  see back then is when they began to use the yellow gas lines and this was a new bank you know 1 + 1 = 2 but not to the "boss"

                  So i put up some cones and caution tape collected my shovels and went home and never went back to that job. and to think he was going to have a backhoe there but something happened and it never showed up. I think his check bounced LOL.

                    HOLY CRAP. That is crazy. I worked in a truck terminal yard which had cross state, high pressure gas transmission lines running thru it about 100 feet away from where we were digging to repair a water leak. Those guys came to locate and stayed there the whole time we were digging up our line. Side note we did dig up a 3" conduit with a 1" telephone line in it. I was abandoned though. At least I think it was, we could pull it out on the building side, so I guess it was no longer used. Also pulled up a private fiber optic line with a bucket tooth once, stupid customers didn't tell us they had one going under the street to their other building.

                      Josh,
                      Do you have anymore on this?

                      I just don't see a three point post hole digger going down that far into the ground, looks like that pipe is over six feet to the top of the pipe.

                      What happened to the tractor, I don't see the burnt carcass of it.

                      Why would someone put a fence post in the middle of a hay field anyway?

                      You have my curosity peaked, could you find out where and when.

                      Thanks

                        found it, I did not think it was due to mechanical damage. Look at the pipe on the left side, it is almost cut or broken square off, like a weld failed.

                        No digging was involved.

                          Still, a great story though and it shows how powerful a gas explosion can be.

                          Last October we had a sewer problem at our home in Binghamton. After several hours, the plumber and drain specialist couldn't clear the line and it was declared that digging was going to be needed. That was late in the day and my plumber said he'd have to make a few calls, before we could proceed.

                          The house is right in the city and I was pleasantly surprised at how quickly everyone came together on this. Within an hour or so, we had the gas company, the electrical company, the city engineer, and even the city's botonist, all show up.

                          Gas line was searched for and discovered, as the original map was over a hundred years old. The electricity company had thier map up to date, but still sent a guy to confirm. The city engineer had maps from the early 80's, but wanted to make sure the excavator kept him informed should something be discovered.

                          The botonist was there to make sure we weren't going to damage a tree if per chance it was something endangered. Once he okay'd that, he had the city come and remove it, right down to the roots.

                          What appeared to me as a simple excavation challenge really gave me an education on the importance of doing some serious checking before digging.

                          As far as "locating", the devices that the plumbing company used were not "Ridgid". Pretty neat stuff though and I wonder what in the world did plumbers do before such devices. As it were, we got close, as detection showed it at the edge of my driveway. We went down just about 10 ft, taking out about four feet on the right side of my driveway. We found nothing and then they started moving further to the right... the sewer line was found about eight feet to the right of driveway, so in all they ended up with this incredible hole, ten feet or so deep by about twelve feet wide. Thankfully they didn't have to take out any of the sidewalk.

                            Installing trace wire is the best idea so far, even if it does get broken at some point in time you can trace some of it out from both ends and get a general idea about where it could be.
