TARIFF FOR GAS SERVICE TXU GAS COMPANY RATE SCHEDULE: 31 i General Transportation Contras.~ Terms and Conditions APPLICABLE TO: ! Entire System ! REVISION: 0 i DATE: EFFECTIVE DATE: ! i PAGE: 7 of 13 A.G.A. Report No. 3 - ANSI/APl 2530. Positive displacement will be performed in accordar~ce with the latest version of ANSI Bt09.1, B1092, or B1093. Turbine metering will be performed ~n acccrdance w~th the latest vers=on of A.G.A. Report No~ 7. Ultrasonic metering will be performed m accordance w~th the latest version of A.G.A, Report No. 9. Electronic Gas Measurement (EGM) will be performed m accordance with the ~atest version of APl Manual of Petroleum Measurement Standards Chapter 21 - Flow Measurement Using Electronic Metering Systems. The unit of measurement of Gas will be 1,000 cubic feet at a base pressure of 14.65 psia and a temperature base of 60 degrees Fahrenheit. Meter measurements will be computed by the Metering Party into such units in accordance with the Ideal Gas Laws for quantity variations due to metered pressure and corrected for deviation using average values of recorded relative density and flowing temperature, or by using the calculated relative density determined by the method mentioned in paragraph (c) below. In no c~rcumstance will the average value o~ flowing temperature be determined for a period of less than one Day. (c) Heating Value and Relative Density, The average heating value (Btu) and retative density of the Gas delivered under any Transportation Agreement by either party may be determined by the use of recording instruments of standard type, which may be installed and operated by the Metering Party at the metering point, or at such other point or points as are mutually agreeable to both parties; provided, however, if there is no Btu/relative density instrument at a particular Receipt or Delivery Point specified m the applicable Transportation Agreement, then the heating value and relative density of the Gas at such point may be determined by "on-site" sampling and laboratory analysis or other reasonable industry standard methods. (d) Measurements Made Only Wh#e Gas Flowing. In Gas measurement computations the determinations for the average values for meter pressure, relative density, and flowing temperature values will be determined only during periods of time when Gas is actually flowing through the meter(s). (e) Gas Industry Standards. Gas industry standards are in the process of being developed by the North American Energy Standards Board, subject to FERC approval. To the extent that Company reasonably deems it necessary, from time to time and at any time, to implement any or all of such standards, Company will have the right to add such standards hereto and/or modify or change the provisions contained herein in order to effect such changes if such changes do not have a material adverse effect on the rights of Customer under any Transportation Agreement. 11. Quality (a) Quality. Each party will deliver to the other party under a Transportation Agreement Gas that is of merchantable quality and is commercially free from water, hazardous substances, hydrocarbon liquids, bacteria, and other objectionable liquids, solids, and/or Gas components. In addition, the Gas delivered by each party under a Transportation Agreement will specifically contain not more than: (i) 0.05% oxygen, (ii) five grains of total sulphur consisting of not more than ¥~ grain of hydrogen sulphide and one grain of mercaptan sulphur per 100 cubic feet of Gas, (iii) 2% by volume of carbon dioxide, (iv) 4% by volume total non-hydrocarbon and inert gases, and (v) seven pounds of water vapor per one million cubic feet of Gas; provided, however, if Customer tenders Gas for transportation upstream of a dehydration plant, Company may, at its option, waive Customer's obligation to deliver dehydrated Gas, subject to Company's continuing right to withdraw such waiver at any time in the future. -84-
