With gas dissipating in the air I guess the worst that can happen is someone ignites it and then you have a little gas flame on your lawn.
That's probably already on YouTube somewhere along with the guy who ignited water coming out of a water pipe (think fracking).
If they don't show up I recommend writing a letter to them containing the phrases "possible gas explosion" and "Board of Inquiry" and "wrongful death" and "disfiguring burns".
That will get them out to your place in a hurry but they will be hopping mad.
Yes, I did that once for a customer who couldn't them out to her place.
