The yellow line is a visual warning of "DANGER" for anyone that has to dig in that area to help keep them from cutting the line.

Doesn't matter, it's code no doubt, and will outlast you.
Anything else you need in that trench before they backfill it? Water line for autofill? Not sure what you can run with a gas line. Probably not electrical, but water maybe. Your inspector would know...
Take pictures of this and any/all open trenches, with good perspective of surrounding areas. Save them somewhere permanent, for future reference of where things are buried.
Yellow line is tracer wire, poly gas pipe can not be picked up by metal detector. Locators can also pulse signal that wire so their wand can find it.
Yep we are on hold now too. Being in some sort of construction (in TX) my whole life you learn the A team (money makers) go back home during the holidays. If they send anyone out during that time it’s the B team, that didn’t have the $ or papers to make the trip. U want the A team.
I was a bit gutted today since it was so nice out, but I’d rather they do a good job than rush it. Will be hoping for good weather for all of us for the next 10 days!
