Sec.16-11-15. Heating value tests—records and reports

(a) Every gas company shall regularly determine the heating value of the gas as supplied to the customers, using standard calorimeter equipment in accordance with accepted methods. At least one such determination shall be made each day except on Sundays and holidays.

(b) Each determination of heating value shall be recorded originally upon a form adopted for that purpose.

(c) When two or more communities are served entirely from a common gas supply, the commission may permit the heating value to be determined at a single suitable location.

(d) The gas company supplying natural gas shall make sufficient tests, or have access to such tests made by its suppliers, as to ascertain the heating value.

(e) These tests shall be made at a location, or locations, which will insure a representative sampling of the gas being sent out to the distribution systems.

(f) Every gas company shall report to the commission, not later than the tenth day of each month, the monthly average, together with the number of tests included in the average, and the maximum and minimum day averages of the heating value of the gas supplied during the calendar month preceding.

(g) The average for any day shall be determined from the record of a recording calorimeter where such record is available, or it shall be taken as the average of the results of all tests of heating value made on that day. The average of all such day averages shall be taken as the monthly average.
