What type of piping is considered non-DOT jurisdictional after the meter outlet?

The correct choice pertains to local authority jurisdictional piping because, after the meter outlet, the regulation and oversight of gas piping is typically transferred from federal jurisdiction, such as the Department of Transportation (DOT), to local authorities. This shift occurs because the piping beyond the meter is often subject to local building codes and safety standards, rather than federal regulations.

This local jurisdiction allows municipalities or local authorities to enforce specific safety measures, installation practices, and maintenance standards that are more tailored to the unique needs of their communities. Such regulations may vary significantly from place to place, which is why local authorities play a critical role in ensuring the safety and integrity of this piping.

Utility jurisdictional piping, as well as residential and commercial piping, usually remain under the purview of utility companies or state regulators until they reach the meter. Therefore, they do not completely fall under local authority jurisdiction until that point.
