That`s correct. Plastic pipe is now sometimes used for gas and it
certainly won`t serve as a ground.

His question was about proximity of a ground rod to a gas line. My
answer was not to worry about ground rod proximity to a gas line so
long as he doesn`t short out the cathodic protection potential which is
imposed on a metal line on the feed side of the meter.
