170 IAC 5-1-21 Gas pressure; allowable variations

Sec. 21. Pressure of Gas. (A) Gas shall be supplied at a pressure never varying by an amount more than fifty percent above or below the normal pressure, as measured at point of delivery to the customer, provided however, that the maximum pressure on any day at point of delivery, shall never be greater than twice the normal minimum pressure on that day at that point, excluding customers being supplied gas under special contracts. (B) Any public utility supplying gas shall not be deemed to have violated the preceding paragraph of this rule, if it can be shown that variations in gas pressure occurring are due to conditions beyond the control of the utility.
