The last owner of our house left a capped metal gas pipe sticking straight out from the wall in the laundry area which is causing an obstruction to a walk way. The plan is to remove the pipe which protrudes about 6 inches and use a plug with the proper compound sealant. There is no shut off valve at the line so I am planning to cut gas flow from the main shut off valve - was planning on just turning on the outside gas bbq after shutting off to remove any pressure in the line. My question is whether there are other consideration to shutting off the main gas valve of the house. I read on the PG&E website that you should only use the shutoff in an emergency and once shut off there may be a delay in returning gas service when turned back on. Don't know what that means or how PG&E would even know about the temporary shut off. It's a relatively easy DIY project but I don't want to miss anything since I'll be dealing with gas. Any thoughts would be appreciated. Thanks in advance.

finally removed ugly 3D wall structure above gas fireplace. Boy did we open a can of worms, found partial or no bat insulation on chases walls. Cold air move more evident, always was cold air coming from fireplace area (had to cover with plastic when not in use) and wall was very cold. Without removing the entire wall and insert to insulate properly, would a closed cell spray foam application work in this area?
