1. (1) Each utility billing its customers on a term basis, or distributing other than straight undiluted natural gas, or distributing from liquefied natural gas (LNG) shall have available a daily record of the BTU value of the gas being sold. Such values may be obtained either from a utility’s own recording calorimeters or from the recording calorimeter of the transmission company which is the supplier.
2. (2) All peak-sharing plants shall have installed recording equipment capable of measuring and recording the BTU of the mixed gas. This may be accomplished by either measuring the specific gravity or the BTU content directly of the mixed gas. These records shall be made available upon request.
