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.
