(k) Instrumentation and equipment to provide Records or samples of gas necessary to determine the

specific gravity, heating value, and/or concentrations of nitrogen or carbon dioxide as required under

Sections 26.6, 26.7 and 26.8 hereof may be installed at representative points along the pipeline in lieu of

installing such instrumentation and equipment at each measuring station.


(l) Upon notice to Shippers, Transporter may prospectively implement and use any future editions or

versions of the American Gas Association or ANSI reports referenced in this Section 26.



26.10 Check Measuring Equipment.


(a) Shipper may install check measurement equipment, provided such equipment does not interfere

with the exercise of Transporter's rights to operate its station under this Tariff.


(b) Transporter, in the presence of Shipper, shall have access to Shipper's check measuring

equipment at all reasonable times, but the reading, calibration and adjustment thereof and the change of

charts shall be performed only by Shipper, unless otherwise agreed upon.


(c) Shipper shall exercise reasonable care in the installation, maintenance and operation of its

equipment so as to avoid any inaccuracy in the determination of the quantity of gas delivered.



(d) The Records from such check measuring equipment shall remain the property of Shipper, but upon

request Shipper will submit to Transporter its Records and charts, together with calculations therefrom, for

inspection, subject to return within 30 days after receipt thereof.


26.11 Calibration and Testing of Meters. The accuracy of all measuring equipment shall be verified by its

operator at reasonable intervals and, if requested, in the presence of representatives of the other party,

but neither Transporter nor Shipper shall be required to verify the accuracy of such equipment more frequently

than once in any 30-day period. If either party at any time desires a special test of any

measuring equipment, or if either party at any time observes an error in any such measuring equipment, it will

promptly notify the other party, and the parties shall then cooperate to secure a prompt verification of the

accuracy of such equipment. The expense of any such special test shall be borne by the requesting party if

the measurement equipment so tested is found not to be in error such that previous Recordings from the

equipment must be corrected under the provisions of Section 26.12 herein.
