DOT jurisdictional piping terminates at which point?

The point of termination for DOT (Department of Transportation) jurisdictional piping is defined as the connection point on the outlet side of the gas meter. This means that DOT regulations and safety standards apply to the gas piping up until it reaches the outlet of the meter.

This distinction is essential because the gas meter serves as a transition point between the utility's responsibility for gas delivery and the customer's responsibility for the piping and equipment beyond the meter. In this context, the jurisdiction defines the extent to which DOT has authority over the gas distribution infrastructure. Regulations aim to ensure safety and compliance in the transportation of natural gas, and understanding where jurisdictional responsibilities shift is crucial for inspections and maintenance.

The other options describe locations either prior to or at points where the responsibility has passed to the customer or a different regulatory entity, which is why they are not considered the terminus for DOT jurisdiction.
