PI-72-0120
From OPS Adv. Bul. no. 72-2
Interpretations
Relates to 49 CFR Part 191
Question: Is a gas leak that occurred inside a house reportable under
the provisions of 49 CFR Part 191?
OPS Interpretation: "...any leak...(an unintended escape of gas) that
is caused by a defect or act on a pipeline facility over which the
Department has jurisdiction is reportable under Part 191. This
assumes that the leak meets the other criteria for reporting that are
stated in those regulations. If, however, the defect or act, and the
escape of the gas resulting therefrom occurs outside our jurisdiction,
then it is not reportable under Part 191.
..."To assist in carrying out the regulatory responsibility, Section
12 of the Act requires operators to '...maintain such records, make
such reports, and provide such information as the Secretary may
reasonably require...' Based upon this authority...reporting is
required with respect to those pipeline facilities and activities
where there is jurisdiction to act. Requiring a report if incident
that proximately results in the escape of gas and danger to the public,
regardless of the physical location of that escape and danger, is a
reasonable exercise of the authority."
..."In short, if the act that causes the escape or danger occurs where
there is authority to regulate a report is required regardless of the
physical location of the escape."
Relates to 49 CFR §192.195
Question: Is there any intent in §192.195 to limit the use of some
types of overpressure protective devices that were previously
permitted under certain conditions under the interim standards such
as relief, monitoring, rupture discs, shut-off and series regulation?
OPS Interpretation..."Except as specifically provided for in
§192.195, there is no intent to limit the type of overpressure
protection device that an operator may use. The operator is free to
choose the device...that will best suit his situation so long as it
complies with applicable requirements of Part 192."
Question: What is the effect of the Occupational Safety and Health
Act of 1970 upon the safety rules and regulation for the transportation
of natural gas and liquids via pipeline?

OPS Interpretation:..."The regulations promulgated under the
authority of the Occupational Safety and Health Act of 1970 and under
the Natural Gas Pipeline Safety Act of 1968 are compatible as they apply
to the different aspects of safety for which the Acts were enacted.
The pipeline regulations apply to the safe transportation of natural
and other gas and liquids by pipeline. The Occupational Safety and
Health regulations apply to the safety of the worker. Where safety
in transportation demands regulations affecting work conditions of
workers then the Department of Transportation assume(s)
jurisdiction."
Relates to 49 CFR §195.210
Question: What would be the reaction of the pipeline safety office
to the encroachment of a surface-holder upon the 50-foot restriction
of §195.210?
OPS Interpretation:..."The 50 foot restriction on §195.210 applies
only to installation of the pipeline and does not affect any subsequent
encroachment by a surface holder. Once the pipeline is in place these
regulations have no limitations on how close surface structures can
be placed to the pipeline. The terms of the operator's right-of-way
would be the only limiting factor."
