§ 59.29. Gas pressure requirements for low-pressure distribution systems.
(a) Maximum pressure. The maximum pressure specified for a low pressure system may not be greater than a pressure which will not cause the unsafe operation of connected and properly adjusted gas utilization equipment or 14 inches of water column (8.1 ounces), whichever is less, at the outlet of the service meter of a low pressure customer.
(b) Minimum pressure. The minimum pressure at the outlet of a service meter of a low pressure customer may not be less than a pressure which will not cause the unsafe or inadequate operation of a connected and properly adjusted gas utilization equipment or 2 inches of water column (1.2 ounces), whichever is greater, unless due to insufficient capacity of the service line owned by the customer.
(c) Changing pressure. A public utility may change the distribution pressure for any system, but if a change is made, all appliances of a customer located within the system shall, if necessary, be readjusted by and at the expense of the utility.
(d) Pressure gauges. A public utility shall maintain and operate on the outlet side of the system regulator station, at least one recording gas pressure gauge of suitable range. If more than one regulator station is used to serve a single pressure system, recording pressure gauges need not be installed for each regulator station. A sufficient number of recording pressure gauges shall be installed and operated in each distribution system to furnish a continuous record of the pressure prevailing in all parts of the system.
