2012 Distribution Best Practices Benchmarking
System Regulation and
Valve Inspection & Maintenance Data Packet
General Definition
Operations and maintenance activities associated with the inspection and maintenance of valves on distribution systems. This includes inspection and maintenance activities required by 192.747 Valve Maintenance-Distribution systems, as well as voluntary company valve inspection programs. Transmission valves or service valves are not part of this study with the exception of Question 9 on automatic shutoff valves and remote control valves.
All field activities associated with the operations and maintenance of pressure control stations requiring periodic inspections as per DOT Part 192. (Excludes Gas Control Personnel)
NOTE: All work within the pressure control station would be included in the labor costs. This would include all regulators, filters, valves, piping, heating equipment, any system metering in the station, any electronic equipment for monitoring, calibration of chart equipment, maintenance of odorization equipment, chart changing and data downloading, , and building and property maintenance.
Service Level Measures
· Number of valves maintained per 100 miles of main
· Percentage of maintained valves found inoperable
· Number of customers per maintained valve
· Percent of Unscheduled visits per pressure control station and city gate station
· Unscheduled visits per pressure control station and city gate station
Productivity Measures
· Labor cost per total valve inspected
· Total cost per total valve inspected
· Labor cost per city gate station
· Labor cost per pressure control station
· Total cost per city gate station
· Total cost per pressure control station
Activities
· Verify valve operation by turning or partial opening or closing
· Any recommended work applied to service valve operation such as lubrication or flushing and cleaning
· Work associated with repairing inoperable valves, or uncovering when paved over
· Cleaning debris from around the valve stem to ensure operation
· Management of valve maintenance records
· Validate valve location
· Station pressure adjustments
· Operations and maintenance/adjustment of electronic monitoring equipment
· Retrofit of regulators or other equipment in existing stations
· Periodic testing, inspection, maintenance of regulators, over-pressurization devices, gate gas metering equipment, all associated valves and all other associated equipment
· Investigation and correction of pressure problems or outages
· Leak testing of all station equipment and piping
· Operations and maintenance of station heating equipment
· Record keeping to support above activities
· Supervision of personnel performing the above activities
· Operations and maintenance of odorization equipment
· Operations and maintenance of liquid removal equipment and filtration
· Chart changing / electronic data downloading
· Building and property maintenance (grass cutting, etc)
· Painting of regulator and station piping

Definitions
City Gate Station
/ All pressure control stations requiring a periodic inspection under Federal Pipeline Safety Regulations (Part 192). A pressure control station that is also considered a point of delivery where ownership of the gas within the pipeline is transferred to the local distribution company. In many cases, it may also include measurement, telemetry and odorization equipment. (Does not include service farm taps.)Curtailment (Pressure) Zone / Network of main shut off by closing a set of emergency/critical valves.
District Regulation Station / All pressure control stations (other than City Gate Stations) requiring a periodic inspection under Federal Pipeline Safety Regulations (Part 192) (Does not include service farm taps.)
Equipment / All equipment within the city gate/system regulation stations, including regulators, filters, odorizers, liquid removal equipment, meters if present, control piping and equipment, valves, pilots, piping, electronic monitoring or metering equipment, and heating equipment
Emergency/Critical Valve / A valve, the use of which is necessary for the safe operation of a distribution system, and covered by D.O.T. 192.747.
Heating Equipment Maintenance
/ Includes operating and maintenance costs associated with heating equipment used in the heating of gas at regulator stations, including boilers, heat exchangers, water and glycol lines and pumps, as well as the associated controls.Labor Costs / The cost of all employee labor, overtime, and contractor labor dollars associated with Pressure Control Station or valve activities. Be sure to include all supervisory labor, secretarial labor, clerical labor, stores labor and all other direct support labor. Note that supervisory labor is defined as the cost of the first level non-working supervisor who directs the activities of hourly workers. Be sure to include only labor dollars in the above. Fringe benefits and overheads are not included.
Record Keeping / Recording and maintenance of all pressure control stations, facility inspection, and maintenance information or the management of valve maintenance records.
Scheduled Visit / All inspections\maintenance required by DOT or company procedures for equipment in the pressure control station
Supervision / Direct oversight of all tasks associated with maintenance of pressure control stations or valves.
Total Costs / All costs associated with Pressure Control Station activities including but not limited to labor, overtime, supervision, fringe benefits, travel, supplies, equipment, overheads, etc.
Unscheduled Visit / Any visit that is the result of a suspected malfunction at a pressure control station.
*Add definitions of ASVs/RCVs:
A Remote Control Valve (RCV) is a valve equipped with electric or gas powered actuators to operate (open or close) the valve based on an order (signal) from a remote location, such as a gas control room.
An Automatic Shut-Off Valve (ASV) is a valve that has electric or gas powered actuators to operate the valve automatically based on data sent to the actuator from pipeline sensors.
