PIPELINE SAFETY REGULATORY INTERPRETATION
Note: A
_________________________________________________________________
pipeline safety regulatory interpretation applies a particular rule to a
particular set of facts and circumstances, and, as such, may be relied upon
only by those persons to whom the interpretation is specifically addressed.
SECTION: 192.625
SUBJECT: Interpretation on the odorization of a single service line served through a farm tap
from a transmission line.
FACTS: A service line is used to deliver gas to a restaurant directly from a transmission
line. Gas in the transmission line is not required to be odorized.
QUESTION: Does the gas in the service line have to be odorized?
INTERPRETATION: Section 192.625(a) requires that gas in distribution lines have a natural
odor or be odorized to the limit prescribed. Since service lines are distribution lines, they are
subject to the odorization requirements of §192.625(a). The exception from odorization provided
by §192.625(b) for some transmission lines does not affect the requirement to odorize gas in
distribution lines connected to an unodorized transmission line.
