SECTION 7.3
MEASUREMENT
VERSION 3.0.0

GENERAL TERMS AND CONDITIONS
7.3. MEASUREMENT 7.3.1. The volume and the total heating value of Gas received and delivered by Transporter shall be determined as follows: 1. The unit of Gas received and delivered by Transporter shall be an MMBtu. 2. The unit of volume, for the purpose of measurement, shall be one cubic foot of natural gas at a pressure base of fourteen and seventy-three one-hundredths (14.73) pounds per square inch absolute, a temperature base of sixty degrees (60o) Fahrenheit (519.67o R Absolute), and without adjustment for water vapor content. 3. Measurement Unit. The Measurement Unit shall be one MMBtu of natural gas and shall be calculated by multiplying the volume delivered in Mcf by a fraction, the numerator of which is the Heating Value and the denominator of which is 1,000. 7.3.2. The factors required to determine the volume of Gas received, such as pressure, temperature, specific gravity, supercompressibility and deviations from Boyle's Law, shall be calculated in accordance with the applicable American Gas Association Bulletin and any modifications and amendments thereof, and applied in a practical manner. 7.3.3. Resolving Differences at the Delivery Point(s) – If the testing and calibration performed at the Delivery Point(s) pursuant to Section 7.4 show that any item of equipment installed by Transporter does not conform to the accuracy requirements of Section 7.4, all previous readings of that item of equipment shall be corrected to zero error for any period which the equipment was known to be in error. If this period is not known, the correction shall be made for a period extending back one-half of the time elapsed since the last testing and calibration performed. During any period when any item of equipment installed at the Delivery Point(s) by Transporter is inoperable or known to be in error, the measurements provided by the corresponding item of equipment installed by Shipper, if any, shall be used if determined to be accurate. If neither item of equipment is operable or accurate, or available in the case of Shipper's equipment, the specification to be measured shall be determined by the parties hereto on the basis of the best data available using the first of the following methods which is feasible: 1. By correcting the error if the percentage of error is ascertainable by calibration, test, or mathematical calculations; or 2. By comparing deliveries made during the preceding period under similar delivery conditions when the equipment was registering accurately.
