GENERAL TERMS AND CONDITIONS (continued)
properly record the temperature of the gas flowing through
the meters. The arithmetic average of the temperature(s)
recorded shall be used in computing gas volumes.
(e) The specific gravity of the gas delivered shall be
determined by the use of a recording gravitometer, which
shall be checked at least once each month, or any other
method mutually agreed upon.
(f) The deviation of the natural gas from Boyle's Law shall be
determined by the use of the tables of formulae published by
the American Gas Association Par Research Project NX-19
corrected for carbon dioxide and nitrogen, or any
superseding applicable tables published by the American Gas
Association, or any method or methods mutually agreed upon.
Determinations of the molecular percentage of N2 and CO2 in
the gas shall be made within thirty (30) days after
commencement of deliveries and at leastquarterly thereafter.
The molecular percentage of N2 and CO2 thus determined will
be used to determine the supercompressibility factors during
the ensuing period, with corrections for specific gravity,
temperature and pressure. For the purpose of this
subparagraph, the results of the deviation tests of the
upstream pipeline delivering natural gas to Transporter
shall be accepted.
3.3 Determination of Receipts and Deliveries - For purposes of
determining the quantities of gas received at any Receipt
Point(s), Transporter will enter into an Operational Balancing
Agreement(s) ("OBA"), with any pipeline that operates inter or
intrastate pipeline facilities which interconnect with
(a) Allocation of Receipts - Unless prohibited by
applicable law or regulation, the quantities of natural
gas received by Transporter at any Receipt Point(s) shall
be allocated among Shippers and services in accordance
with allocation procedures contained in the OBA agreed to
by Transporter and the upstream pipeline serving that
