GENERAL TERMS AND CONDITIONS

MEASUREMENT AND MEASUREMENT EQUIPMENT

 

 

3.10 Metering Record Preservation. Pipeline shall preserve on microfilm or otherwise for a

period of at least three years all test data, charts and other similar records.

 

3.11 Pipeline shall process measurement data corrections within six months of the production

month, with a three-month rebuttal period. This provision shall not apply in the case of

deliberate omission or misrepresentation or mutual mistake of fact. The parties' other

statutory or contractual rights shall not otherwise be diminished by this provision.

 

3.12 Electronic Gas Measurement. Pipeline shall have the right to require and may install or

cause to be installed electronic Gas measurement and control equipment at all points.

 

A. Accuracy. Where electronic Gas measurement is used, the system shall use

instruments designed to provide overall measurement accuracy of +/-1 percent of

flow, taking into account all the sources of error, including calibrated span of

instruments, linearity, hysteresis, repeatability, ambient temperature, stability,

vibration, and power supply fluctuations.

 

B. Computation. The electronic Gas measurement equipment shall, at a minimum, perform

flow calculations per AGA-3, AGA-7 and AGA-9 requirements, as appropriate. As the

flow calculation methods are revised from time to time, new releases shall be

implemented within twelve months from the release date.

 

C. Calibration and Testing Equipment. All test and calibration equipment shall be

certified and maintained pursuant to Pipeline's current published standard operating

procedures as revised from time to time.

 

3.13 New Measurement Methods. If at any time a new method or technique is developed with

respect to Gas measurement or the determination of the factors used in such Gas

measurement, such new method or technique may be used by Pipeline provided that it is

generally accepted within the industry.

 

3.14 Pressure Protection. Pressure regulation, pressure override and pressure valve or other

pressure or flow limiting devices installed and operated by Pipeline at the measuring

station or at or near each interconnection of Pipeline's facilities with facilities of

third parties shall only be for the purpose of operation and protection of Pipeline's

system, including its measurement equipment. In no event shall Pipeline be responsible

for over-pressure protection on Customer's facilities.

 

3.15 Measurement By Third Parties. If any measuring equipment is owned or operated by a party

other than Pipeline, such measuring equipment and measurement shall be operated either in

a manner consistent with the operator's own tariff or in a manner consistent with the

terms of this Section 3.
