In the process of installing CSST (corrugated stainless steel tubing) with existing black steel natural gas piping. The CSST will be used for a retrofit, and will be connected between 2 black steel pipe connections. The black steel piping is bonded & grounded to the house ground wire (#6, to panel ground bus). Does the CSST also have to be grounded & bounded since it is connected to the black steel pipe that is already grounded? My town uses IFGC 2009, I've read it, but unsure on my specific situation.

Ask your local electrical inspector. Some in NJ have told me that they want a bond connection on the black pipe at the meter. Others have told me it is not required. I don't know if it varies by town, or if the inspectors are not on the same page.
