GENERAL TERMS AND CONDITIONS

(Continued)

 

3.3. Resolving Differences at the Delivery Point(s) – If the testing and calibration

performed at the Delivery Point(s) pursuant to Section 4 show that any item of

equipment installed by Transporter does not conform to the accuracy requirements

of Section 4, all previous readings of that item of equipment shall be corrected

to zero error for any period which the equipment was known to be in error. If

this period is not known, the correction shall be made for a period extending

back one-half of the time elapsed since the last testing and calibration per-

formed. During any period when any item of equipment installed at the Delivery

Point(s) by Transporter is inoperable or known to be in error, the measurements

provided by the corresponding item of equipment installed by Shipper, if any,

shall be used if determined to be accurate. If neither item of equipment is

operable or accurate, or available in the case of Shipper’s equipment, the speci-

fication to be measured shall be determined by the parties hereto on the basis of

the best data available using the first of the following methods which is feasible:

 

3.3.1. By correcting the error if the percentage of error is ascertainable by

calibration, test, or mathematical calculations; or

 

3.3.2. By comparing deliveries made during the preceding period under similar

delivery conditions when the equipment was registering accurately.

 

3.4. Measurement of Heating Value, Carbon Dioxide, Oxygen, Nitrogen and Hydrogen Sulfide

 

Transporter’s Gas chromatograph installed at the Receipt Point or other suitable

as determined by Transporter, upstream Gas chromatograph shall be used to measure

the heating value, carbon dioxide, oxygen and nitrogen levels in the Gas stream.

 

3.5. Determination of Total Delivered MMBtu

 

The total number of MMBtus delivered shall be determined by Section 3.1. If the

total MMBtu results obtained by use of Transporter’s equipment differ by two per-

cent or more from the results obtained by use of Shipper’s check metering equip-

ment, then Transporter and Shipper shall each be required to calibrate its mea-

surement equipment. If such calibrations indicate that Transporter’s measurement

equipment is not within the tolerance levels set forth in Section 3.3 and that

Shipper’s measurement equipment is within the tolerance levels set forth in

Section 3.3., then Shipper’s measurement equipment shall be used. If such cali-

brations indicate that neither parties’ measurement equipment is within the

tolerance levels set forth in Section 3.3, then the provisions of Section 3.4

shall be followed to resolve any measurement inaccuracies.
