GENERAL TERMS AND CONDITIONS

(Continued)

gravitometer shall be considered as the specific gravity of the

gas delivered during such period. In the event a continuous

sampler is used, the specific gravity of the composite sample so

taken shall be considered as the specific gravity of the gas

delivered during an applicable period as determined by

Transporter. In the event a spot sample is taken or a

continuous gas sampler is used, the specific gravity of the

composite sample so taken shall be considered as the specific

gravity of the gas delivered during an applicable period as

determined by the Transporter. All specific gravity

determinations made with a chromatograph shall use physical gas

constants for gas compounds as outlined in the 1985 edition of

A.G.A. Report No. 3 (ANSI/API 2530, GPA 8185) on "Orifice

Metering of Natural Gas" with any subsequent amendments or

revisions as may be acceptable to Transporter, and shall meet

generally accepted industry standards and practices. Specific

gravity shall be determined to the nearest one thousandth

(0.001).

delivery point is not determined by any one of the methods

described above, the specific gravity of the gas delivered

during a month shall be assumed to be the same as the weighted

average of the specific gravity of the gas along the same

pipeline segment determined by any of the methods described

above during such period.

any agreement between Transporter and Shipper 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 for the method set

forth herein if agreeable to Transporter, and meets generally

accepted industry standards and practices.

for the closing of measurement is five (5) business days after

the business month. For treatment of measurement prior period

adjustments, treat the adjustment by taking it back to the

production month. A meter adjustment becomes a prior period

adjustment after the fifth business day following the business

month. Measurement data corrections should be processed within

six months of the production month with a three month rebuttal

period. This time limitation will not apply in cases of

deliberate omission or misrepresentation or mutual mistake of

fact. Parties’ other statutory or contractual rights shall not

otherwise be diminished by this provision. Any measurement

prior period adjustments will be reported in the original

production month and will be reported with the restated line

item with new total
