GENERAL TERMS AND CONDITIONS

 

(d) Square Root Error. If unacceptable square root error or

gauge line error is caused by an interconnecting company's equipment or by a

shipper on the interconnecting company pipeline, Southern Trails will refuse

to accept gas from the interconnecting pipeline at that location until the

problem is corrected. Unacceptable square root error is defined to be equal

to or greater than 0.5%. If there is a disagreement over the degree of error

between Southern Trails and the operator of the source, a mutually agreeable

independent third-party will be requested to determine the source and degree

of error. The party deemed responsible for the pulsation source will incur

all costs for the consultation and the installation of remedial devises or

filtering equipment, as necessary.

 

(e) New Standards. Southern Trails may adopt the most recent

edition of: API Chapter 14.3; AGA Report No. 3, Part 2; AGA Report No. 7; and

AGA Report No. 9.

 

12.9 New Measurement Techniques. If a new method or technique is

developed for gas measurement, the new method or technique may be substituted

by Southern Trails. Southern Trails will promptly inform all Shippers of any

new techniques adopted.

 

12.10 Rights Concerning Measurement Equipment.

 

(a) Southern Trails and the operator of any interconnecting

facility, in the presence of each other or their contractually designated

representative, may have access to the other's measurement equipment at all

reasonable times for installing, reading, cleaning, changing, repairing,

inspecting, testing, calibrating or adjusting done in connection with the

other's measurement equipment. Only the party owning the equipment may

perform these operations, unless otherwise agreed. The failure of either

party to witness such operations will not affect the validity of the

operations.

 

(b) The records from measurement equipment will remain the

property of the party owning the equipment, but within ten days of a request,

each will permit the other party to inspect its records and data, together

with related calculations.

 

(c) The measurement equipment of the operator of the

interconnecting facility will be for check purposes only and, except as

expressly provided in these General Terms and Conditions, will not be used in

the custody measurement of gas.
