Installation and Maintenance of
Meters and Pressure Regulators
1.
Protection of Meters, Tanks and Distribution System Facilities from
Damage from Motorized Vehicles or Equipment
Gas meters, aboveground tanks, domes of underground tanks,
and distribution system facilities located adjacent to a roadway, street,
alley, driveway, easement or otherwise susceptible to damage from motor
vehicles shall be provided protective barriers on each side exposed to
vehicular traffic.
2.
Accessibility and Location of Pressure Regulators at Meters or Service
Piping
Pressure regulators installed at meters or on service piping
locations shall conform to the following requirements:
a. Regulators shall be installed:
i. With the screened vent pointed down, or
under a protective cover that will prevent blockage of the vent by rain, snow,
ice or debris;
ii. At least 5 feet
away from mechanical ventilation air intakes, openings into direct-vent (sealed
combustion system) appliances, or any source of ignition, such as but not
limited to electrical meters.
b. Regulators shall not be direct
buried.
3.
Hazardous Equipment Procedure
By July 1, 2012, LPG suppliers shall implement modified
operation and maintenance procedures that include a "Red Tag" or hazardous
equipment procedure for suspending service to a customer's system when a
hazardous condition is noticed that makes continued delivery of LPG
unsafe.
B.
Installation and Maintenance of Mains and Service Lines
1.
Installation of Plastic Pipe,
Warning Tape, and Tracer Wire
a.
Plastic pipe that is not encased in metallic piping must have an electrically
conductive tracer wire or other approved means of locating the pipe. To
facilitate location of buried plastic pipe, where plastic pipe is installed or
replaced the following location methods shall be used.
i. A tracer wire shall be installed adjacent
to the piping. Tracer wire may not be wrapped around the pipe and must not
contact the pipe. Tracer wire or other metallic elements installed for pipe
locating purposes must be resistant to corrosion damage, either by use of
coated copper wire or by other means.
ii. Continuous gas pipeline warning tape
shall be placed above piping installed by open trenching, and separated from
the piping by a minimum of 6 inches.
C.
Directional Boring Operations
Each LPG operator shall:
1. Develop written procedures for conducting
directional boring activities for the installation of gas pipeline facilities
prior to engaging in directional boring;
2. Train its operating personnel including
locators in the specific requirements and hazards associated with directional
bores.
D.
Marking
of Containers
1. All LPG operator-owned
containers, aboveground or underground, installed at consumer locations shall
be marked in a legible manner with the name and telephone number of the owner
by decal, tag, stencil, or similar marking.
2. Containers gained through acquisition
shall be marked as soon as possible, but no later than 30 days after
acquisition.
