GENERAL TERMS AND CONDITIONS

(continued)

 

If, upon any test, any measuring equipment is found to be in

error, such errors shall be taken into account in a practical

manner in computing the deliveries. If the resultant aggregate

error in the computed receipts or deliveries is not more than two

percent (2%), then previous receipts or deliveries shall be

considered accurate. All equipment shall, in any case, be

adjusted at the time of test to record correctly. If, however,

the resultant aggregate error in computing receipts or deliveries

exceeds two percent (2%) at a recording corresponding to the

average hourly rate of Gas flow for the period since the last

preceding test, the previous recordings of such equipment shall be

corrected to zero error for any period which is known definitely

or agreed upon, but in case the period is not known definitely or

agreed upon, such correction shall be for a period extending over

one-half of the time elapsed since the date of the last test, not

exceeding a correction period of sixteen (16) Days.

 

4.4 In the event any measuring equipment is out of service,

or is found registering inaccurately and the error is not

determinable by test, previous recordings of receipts or

deliveries through such equipment shall be determined as

follows, provided however, that the correction period

shall not exceed six (6) months and that Parties' other

statutory or contractual rights shall not otherwise be

diminished by this standard:

 

(a) By using the registration of any check meter or meters,

if installed and accurately registering, or in the

absence of (a);

(b) By correcting the error if the percentage of error is

ascertainable by calibration, special test or

mathematical calculation, or in the absence of both (a)

and (b) then;

(c) By estimating the quantity of receipt or delivery, based

on receipts or deliveries during preceding periods under

similar conditions, when the meter was registering

accurately.

 

4.5 If at any time during the term hereof, a new method or

technique is developed with respect to Gas measurement or

the determination of the factors used in such Gas

measurement, such new method or technique may be

substituted upon mutual agreement thereto by both

parties.

 

4.6 The parties agree to preserve for a period of at least

three (3) years or such longer period as may be required

by public authority, all test data, charts, if any, and

other similar records.

 

5. QUALITY

5.1 Heat Content

Heat content shall mean the gross heating value per cubic

foot of Gas delivered at the Point of Receipt and Point

of Delivery. The Gas at the Point of Receipt shall not

have a heat content less than 965 BTU or greater than

1,110 BTU per cubic foot when determined on a dry basis.

The total heating value per cubic foot of Gas at the

Points or Receipt or Delivery shall be determined by one

of the following methods:
