Current through June, 2024
(a)
				  General requirements. Except as provided in section 6-77-69, each pipeline that
				  is connected to a gas source so that the maximum allowable operating pressure
				  could be exceeded as the result of pressure control failure or of some other
				  type of failure, must have pressure relieving or pressure limiting devices that
				  meet the requirements of sections 6-77-70 and 6-77-71.
(b) Additional requirements for distribution
				  systems. Each distribution system that is supplied from a source of gas that is
				  at a higher pressure than the maximum allowable operating pressure for the
				  system must:
(1) Have pressure regulation
				  devices capable of meeting the pressure, load, and other service conditions
				  that will be experienced in normal operation of the system, and that could be

Current through June, 2024
(a) If the maximum
				  actual operating pressure of the distribution system is under 60 p.s.i.g. and a
				  service regulator having the following characteristics is used, no other
				  pressure limiting device is required:
(1) A
				  regulator capable of reducing distribution line pressure to pressures
				  recommended for household appliances;
(2) A single port valve with proper orifice
				  for the maximum gas pressure at the regulator inlet;
(3) A valve seat made of resilient material
				  designed to withstand abrasion of the gas, impurities in gas, cutting by the
				  valve, and to resist permanent deformation when it is pressed against the valve
				  port;
(4) Pipe connections to the
				  regulator not exceeding two inches in diameter;
(5) A regulator that, under normal operating
				  conditions, is able to regulate the downstream pressure within the necessary
				  limits of accuracy and to limit the build up of pressure under no-flow
				  conditions to prevent a pressure that would cause the unsafe operation of any
				  connected and properly adjusted gas utilization equipment;
(6) A self-contained service regulator with
				  no external static or control lines.

					 limiting device must:
(1) Be
				  constructed of materials such that the operation of the device will not be
				  impaired by corrosion;
(2) Have
				  valves and valve seats that are designed not to stick in a position that will
				  make the device inoperative;

				  designed and installed so that it can be readily operated to determine if the
				  valve is free, can be tested to determine the pressure at which it will
				  operate, and can be tested for leakage when in the closed position;
(4) Have support made of noncombustible
				  material;
(5) Have discharge
				  stacks, vents, or outlet ports designed to prevent accumulation of water, ice,
				  or snow, located where gas can be discharged into the atmosphere without undue
				  hazard;
(6) Be designed and
				  installed so that the size of the openings, pipe, and fittings located between
				  the system to be protected and the pressuring relieving device, and the size of
				  the vent line, are adequate to prevent hammering of the valve and to prevent
				  impairment of relief capacity;
(7)
				  Where installed at a district regulator station to protect a pipeline system
				  from overpressuring, be designed and installed to prevent any single incident
				  such as an explosion in a vault or damage by a vehicle from affecting the
				  operation of both the overpressure protective device and the district
				  regulator; and
(8) Except for a
				  valve that will isolate the system under protection from its source of
				  pressure, be designed to prevent unauthorized operation of any stop valve that
				  will make the pressure relief valve or pressure limiting device
				  inoperative.

				  pressure that produces a hoop stress of seventy five percent of SMYS, whichever
				  is lower;
(B) If the maximum
				  allowable operating pressure is 12 p.s.i.g. or more, but less than 60 p.s.i.g.,

				  to which it is attached, and be designed to satisfactorily withstand all
				  stresses without failure by fatigue;

				  takeoff line as near as practicable to the point of takeoff. Blowdown valves
				  must be installed where necessary;

				  line must be protected from anticipated causes of damage and must be designed
				  and installed to prevent damage to any one control line from making both the
				  regulator and the over-pressure protective device inoperative.
