GENERAL TERMS AND CONDITIONS
(a) In the case where an online chromatograph is used,
the results will be applied continuously during calculation. The
average of the hourly heating value during periods of flow each Day
shall be recorded and considered as the heating value of the Gas
delivered to MEP or Shipper.
(b) In the event a continuous Gas sampler is
installed, then the heating value of the composite sample so taken
shall be considered as the heating value of the Gas for the
applicable period. Alternatively, the results may be applied
prospectively beginning on the Day the results become available after
agreement by both parties.
(c) If spot samples are taken, the samples shall be
run on the measuring party's chromatograph at another location. The
result of a spot sample shall be applied to Gas deliveries as of the
Day the results are available and for all succeeding Days until a new
sample is taken.
(d) All heating value determinations made with a
chromatograph shall use physical gas constants for Gas compounds as
outlined in the GPA Std 2145-00 Rev 1 Table of Physical Constants of
Paraffin Hydrocarbons and other Compounds of Natural Gas and any
subsequent amendments or revisions to such Report to which the
parties may mutually agree. The moisture content of the Gas shall be
determined as often as necessary and practical to determine the
actual heating value of the Gas stream.
(e) The calculations (for Btu) shall be based on dry
Gas if the Gas at the measurement points contains less than five (5)
pounds of water per MMcf. If the Gas at the measurement points
contains more than five (5) pounds of water per MMcf, the appropriate
factor determined by MEP in the exercise of its reasonable judgment
for the actual water vapor content will be applied to the Btu
calculations to correct for this water content.
(f) The specific gravity of the Gas flowing through
the meter or meters may be determined by the use of a chromatograph
or by analysis of Gas collected in spot and continuous samplers.
Specific gravity shall be updated whenever the heating value of the
Gas is updated. All specific gravity determinations made with a
chromatograph shall use physical Gas constants for Gas compounds as
