GENERAL TERMS AND CONDITIONS

(continued)

14. MEASUREMENT & MEASUREMENT EQUIPMENT (continued)

(e) The temperature of the gas passing through the meters

shall be determined by the use of electronic

transducers, recording thermometer or other temperature

measuring devices. The instantaneous measurement from

the electronic measurement equipment or the arithmetic

average of the temperature recorded each Day shall be

used in computing gas quantities.

(f) The specific gravity of the gas flowing through the

meters shall be determined by gas chromatographic

analysis, recording gravitometer, or continuous or spot

sampling methods, unless otherwise mutually agreed upon

by Customer and Pipeline. The arithmetic average of

the specific gravity recorded during each 24-hour Day

shall be used in computing gas quantities or other

periodic measurements within a shorter time frame or

instantaneous specific gravity measurements may be

applied to metering instruments to provide the quantity

computation.

(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 - 1994, (ANSI/API

2530), and any subsequent amendments thereof as may be

mutually agreed upon by Customer and Pipeline.

(h) The Total Heating Value shall be measured, unless

otherwise agreed by the parties concerned, by methods

in accordance with acceptable industry practice, such

as, but not limited to, recording calorimeter(s) or gas

chromatograph(s) located at appropriate points. The

arithmetic average of the heating value recorded each

24-hour Day and as adjusted to conditions as specified

in Section 1 of the GT&C, or other periodic

measurements within a shorter time frame as Pipeline

shall select, shall be used for computations.

(i) The deviation of the gas delivered hereunder from

Boyle's and Charles' Laws shall be determined in

accordance with, but not limited to, the published

recommendations of the American Gas Association's

Report No. 3, Revised - 1994 and the American National

Standards Institute as Pipeline deems to be in

accordance with accepted industry practice.
