GENERAL TERMS AND CONDITIONS
4. MEASUREMENT OF GAS (Continued)
4.4 Temperature and Specific Gravity. The following measurement
factors shall be given due consideration.
(a) The temperature of the natural gas flowing through each meter
shall be an assumed temperature arrived at by agreement or the
actual measured temperature.
(b) The specific gravity of the gas shall be determined by the
party operating the meter by calculation, adjusted for any
difference between the specific gravity in the ideal state and in
the real state in accordance with published procedures accepted by
the American Gas Association.
4.5 Notice of Equipment Tests. Unless otherwise agreed to by the
parties, the party operating the measurement facilities shall give
notice to the other party of the time and location of all tests of gas
delivered hereunder or of any equipment used in measuring or determining
the nature or quality of such gas, in order that such other party may
conveniently have its representative present. Should the non-operating
party reasonably not be satisfied with any such test, it shall so notify
the operating party and the operating party shall perform such retests
as may be necessary to assure an accurate test.
4.6 Meter Testing. The accuracy of measurement equipment shall be
verified at reasonable intervals by the party operating such equipment,
and if requested, in the presence of representatives of the other party,
unless otherwise agreed to by the parties. If either party notifies the
other that it desires a special test of any measurement equipment, the
operating party shall cooperate to secure an immediate verification of
the accuracy of such measurement equipment and joint observation of any
adjustments. The payment for all such tests shall be borne by the
party requesting the test, unless otherwise agreed to by the parties.
4.7 Check Meters and Non-Interference. Either party may install and
operate check meters at its option and expense to check the other
party's primary measurement equipment, but measurement of gas shall be
by the measurement equipment of the parties identified in Section 4.3.
Such check meters shall be installed so as not to interfere with the
operation of the primary measurement equipment of such parties. The
parties shall exercise care in the installation, maintenance and
operation of check measuring, pressure regulating equipment or gas
compressors so as to prevent any inaccuracy in the determination of the
quantity or quality of gas being measured. If unacceptable square root
error or gauge line error shifts occur, the installation of pulsation
