I always thought a natural gas line was under low pressure and only the reduction in a feed line at the house(or what ever) produces higher pressure....I don't think multitple leaks in a main line over 12 mile stretch has enough pressure to blow mud and water 14ft,this sounds like a natural source.

Distribution lines are relatively low pressure.

I'm thinking more along the lines of a feeder pipeline from a wellhead or field somewhere out there. Much higher pressures are involved.

Nope. The 36" natural gas line that I help to maintain is operated at 1450 psi. Even a small leak is very noisy and dangerous.

There was a pipeline rupture in NJ back in the early 90's or late 80's that wiped out a big apartment complex. They run the stuff at some big pressures in transfer. Local utilities do use much lower pressures.
