PART 1

GENERAL TERMS AND CONDITIONS

(Continued)

 

14.8 Measurement. Questar may install orifice, turbine, positive

displacement, ultrasonic meters or other measurement devices. They will be

installed and operated in accordance with then-approved AGA and API

recommendations, where available.

 

(a) Orifice Meters. All orifice meters will be installed and gas

volumes computed according to the standards prescribed in AGA Report No. 3,

Part 2 and API Chapter 14.3.

 

(b) Turbine Meters/Positive Displacement Meters. All turbine

meters will be installed and gas volumes computed according to the standards

prescribed in AGA Report No. 7 and AGA ANSI B109.3.

 

(c) Ultrasonic Meters. All ultrasonic meters will be installed

and gas volumes computed according to the standards prescribed in AGA Report

No. 9.

 

(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, Questar 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 Questar 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 devices or

filtering equipment, as necessary.

 

(e) New Standards. Questar 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.
