(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



(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 shall 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



(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
