(G) When orifice meters are used, the computation of Quantities of Gas delivered

shall be in accordance with the recommendations as published by the American Gas

Association's Report No. 3, Revised - 1990, and the ANSI/API 2530, First Edition,

and any subsequent amendments thereof as may be mutually agreed upon by Customer

and Pipeline.


(H) The Total Heating Value shall be determined by gas chromatographic analysis or

by other methods mutually agreed upon by Customer and Pipeline. The arithmetic

average of the heating value recorded each 24-hour day and as adjusted to

conditions as specified in Section 1 of the General Terms and Conditions, or

continuous instantaneous heating value measurements, shall be used for

computations requiring energy characteristics.


(I) The deviation of the Gas delivered hereunder from Boyle's and Charles' Laws s

hall be determined by gas chromatographic analysis or by analytical methods

mutually agreed upon by Pipeline and Customer. The amount of nitrogen and carbon

dioxide contained in the Gas shall be determined, for the purpose of determining

the deviation factors, every three (3) months or at such other intervals as is

found expedient.


7.2 Measurement Operations and Equipment


Measurement Operations shall include, but not be limited to, the operation, calibration

and testing of the RTU, transducers, chart recorders, meter runs, gas quality

monitoring devices, control valves and responsibility for quantity calculations for the

measurement facility. Pipeline may allow Customer or third parties the right to

perform Measurement Operations, provided that such Customer or third party furnishes to

Pipeline all data required for flow computation and can meet Pipeline's measurement and

operating standards; and provided, further, such Customer or third party which performs

such Measurement Operations shall be responsible for any and all associated costs of

such Measurement Operations unless otherwise agreed by Pipeline and Customer or third

party. Measurement equipment shall consist of the necessary metering devices, designed

and installed in accordance with the current published recommendations of the American

Gas Association or as mutually agreed upon by Customer and Pipeline, measurement

equipment shall be installed, operated and maintained at or on each interconnection of

Pipeline's facility with facilities of third parties; provided, however, 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) Where orifice measurement equipment is to be used, it shall utilize "Flange Tap

Connections" and the static pressure shall be measured at the down-stream flange

tap connection.


(B) An electronic temperature transducer, a recording thermometer or other mutually

acceptable device shall be installed at the measuring station to continuously

measure the flowing Gas temperature.
