Current through Register Vol. XLI, No. 28, July 12, 2024
7.1. Heating value requirements.
7.1.1. Minimum heating value -- The minimum
				average monthly heating value of any gas delivered into a distribution system
				shall not be less than one thousand (1,000) Btu per cubic foot for gas
				transported into West Virginia. When gas produced within this State has a
				heating value of less than one thousand (1,000) Btu per cubic foot, the utility
				shall furnish the Commission an analysis of the gas along with any other
				information the Commission may desire, prior to the delivery of the gas into a
				distribution system.
7.1.2.
				Extraction of hydrocarbons -- No gas treated for the extraction of hydrocarbons
				shall be delivered for distribution where the heating value has been reduced
				lower than one thousand (1,000) Btu per cubic foot.
7.1.3. Reports to Commission.
7.1.3.a. Each utility shall report to the
				Commission, annually the average heating value of its gas delivered into its
				system.
7.1.3.b. A utility whose
				natural gas is treated by itself or others for the extraction of hydrocarbons
				shall report to the Commission the extractions in accordance with the Uniform
				System of Accounts as prescribed by the Federal Energy Regulatory Commission,
				Account Nos. 770 through 791.
7.1.3.c. A utility whose natural gas is
				treated for the extraction of hydrocarbons shall report to the Commission the
				annual average heating value and specific gravity of the gas entering and
				leaving each extraction plant.
7.1.4. Method of determining heating value.
7.1.4.a. Each utility shall determine the
				average heating value of its gas by calorimeter, A. J. W. Headlee formula or
				other approved methods.
7.1.4.b.
				Determination of heating value shall be made of gas drawn from parts of the
				distribution system or pipelines remote from the laboratory, with such
				frequency and in such manner as is necessary to establish the average monthly
				heating value.
7.1.4.c. The heating
				value shall be the total heating value expressed at 14.73 psi absolute pressure
				and saturated with water vapor when determined by calorimeter or chemical
				analysis.
7.1.4.d. Calorimeter
				accuracy, as well as the method of determining heating value, shall be subject
				to the approval of a designated representative of the Commission.
7.1.5. Record of tests.
7.1.5.a. Each utility shall adopt a standard
				form for recording the results of heating value tests. Each determination of
				heating value shall be recorded originally upon the form adopted for that
				purpose, and the records shall be retained for a period of three (3) years.
				Where heating value is determined by an approved type recording calorimeter or
				recording gravitometer, the charts removed from such calorimeter or
				gravitometer will be deemed sufficient to comply with this rule.
7.1.5.b. It is not the intent of this rule
				that recording calorimeters or recording gravitometers be installed but the
				method of determining the average heating value shall be approved by a
				representative of the Commission.
