There's regulation and then there's regulation. Most of my clients build gathering systems (outside of DOT jurisdiction) to B31.8, some don't. The ones that do are in a pretty good position if population encroachment forces a non-DOT line into DOT jurisdiction. The ones that don't are just plain screwed.
I guess I've missed the news for the last couple of months (big job, taking nights and weekends), who is proposing these regulations?
