Don't be surprised if the gas company is not willing to hand that information out to the public. Most if not all Gas companies will either locate a line or have a contractor locate it for construction purposes. However they will not give out maps or data showing all their facilities to the public. If the specific location of all the gas lines, valves and regulator stations were shown on a map and available to the public. Unfortuniately in todays world, that would be a huge security risk and one they are not willing to take.
