Current through June, 2024
(a) Except for
				  pipelines listed in subsection (c), each operator of a buried pipeline shall
				  carry out in accordance with this section a written program to prevent damage
				  to that pipeline by excavation activities. For the purpose of this section,
				  "excavation activities" include excavation, blasting, boring, tunneling,
				  backfilling, the removal of the above ground structures by either explosive or
				  mechanical means, and other earth moving operations. An operator may perform
				  any of the duties required by subsection (b) through participation in a public
				  service program, such as a "one-call" system, but such participation does not
				  relieve the operator of responsibility for compliance with this
				  section.
(b) The damage prevention
				  program required by subsection (a) must, at a minimum:
(1) Include the identity, on a current basis,
				  of persons who normally engage in excavation activities in the area in which
				  the pipeline is located;
(2)
				  Provide for notification of the public in the vicinity of the pipeline and
				  actual notification of the persons, identified in paragraph (1), of the
				  following as often as needed to make them aware of the damage prevention
				  program:
(A) The program's existence and
				  purpose; and
(B) How to learn the
				  location of underground pipelines before excavation activities are
				  begun;
(3) Provide a
				  means of receiving and recording notification of planned excavation
				  activities;
(4) If the operator has
				  buried pipelines in the area of excavation activity, provide for actual
				  notification of persons who give notice of their intent to excavate of the type
				  of temporary marking to be provided and how to identify the markings;
(5) Provide for temporary marking of buried
				  pipelines in the area of excavation activity before, as far as practical, the
				  activity begins;
(6) Provide as
				  follows for inspection of pipelines that an operator has reason to believe
				  could be damaged by excavation activities:
(A) The inspection must be done as frequently
				  as necessary during and after the activities to verify the integrity of the
				  pipeline; and
(B) In the case of
				  blasting, any inspection must include leakage surveys.

(a) Each operator
				  shall establish written procedures to minimize the hazard resulting from a gas
				  pipeline emergency. At a minimum, the procedures must provide for the
				  following:
(1) Receiving, identifying, and
				  classifying notices of events which require immediate response by the
				  operator;
(2) Establishing and
				  maintaining adequate means of communication with appropriate fire, police, and

				  first and then property;
(6)
				  Emergency shutdown and pressure reduction in any section of the operator's
				  pipeline system necessary to minimize hazards to life or property;
(7) Making safe any actual or potential
				  hazard to life or property;
(8)
				  Notifying appropriate fire, police, and other public officials of gas pipeline
				  emergencies and coordinating with them both planned responses and actual
				  responses during an emergency;
(9)
				  Safely restoring any service outage; and
(10) Beginning action under section 6-77-165,
				  if applicable, as soon after the end of the emergency as possible.
