GENERAL TERMS AND CONDITIONS

4. MEASUREMENT OF GAS

4.1 Unit of Volume.

The unit of volume for the purpose of measurement shall be one (1)

cubic foot of gas at a base temperature of 60F. and at a base pressure

of 14.73 psia. Such measured volumes, converted to Mcf, shall be

multiplied by their gross heating value per cubic foot and divided by

1,000 to determine Dth received and delivered hereunder. The unit of

volume for the purpose of balancing total receipts and deliveries of gas

hereunder shall be one Dth.

4.2 Computation of Volume. The volumes of gas measured hereunder

shall be computed in accordance with specifications prescribed by the

American Gas Association, applied in a practical and appropriate manner.

The absolute atmospheric pressure used for volume calculations shall be

the average atmospheric pressure determined by calculations based on the

actual elevation above sea level of the meter at the place of

measurement.

4.3 Meters or Measurement Equipment. For purposes of this Section,

Meters or Measurement Equipment shall mean the primary measurement

element (i.e., orifice plate, turbine meter, etc.), and recording

instruments. Gas delivered to Transporter at the Receipt Point(s)shall

be measured by measurement equipment installed, operated and maintained

at or near such Receipt Point(s). Gas delivered by Transporter at the

Delivery Points shall be measured by measurement equipment installed,

operated and maintained at or near such Delivery Points. Where orifice

meters are used they shall be installed and operated in accordance with

the specifications prescribed in ANSI/API 2530 as supplemented and

modified from time to time, applied in a practical and appropriate

manner. Where positive displacement meters, turbine meters, or other

measuring devices are used, they shall be installed and operated in

accordance with recommendations of the American Gas Association, where

available. The respective meter, meter readings and meter charts shall

be accessible at all reasonable times to inspection and examination by

the non-operating party. Calibration and adjustment of meters and

changing of charts shall be done only by the party owning and operating

the measurement facilities, unless otherwise agreed to by the parties.
