1.33 "Gross Heating Value" shall mean the number of Btu's produced by the

combustion, at a constant pressure, of the amount of Gas which would

occupy a volume of one cubic foot at a temperature of 60 degrees

Fahrenheit on a water-free basis at a pressure of 14.73 p.s.i.a.

with air of the same temperature and pressure as the Gas, when the

products of combustion are cooled to the initial temperature of Gas

and air and when the water formed by combustion is condensed to the

liquid state. The value so determined shall be adjusted to reflect

actual conditions of pressure and temperature. The calculations

shall be based on dry Gas if the Gas at the measurement points

contains less than 5 pounds of water per MMcf. If the Gas at the

measurement point contains more than 5 pounds of water per MMcf, an

appropriate correction factor determined by Transporter for the

actual water vapor content in the delivered Gas stream will be

applied to the Btu calculations to correct for this water content.
