whether the potential system integrity problem is anticipated to be

caused by excess gas or a gas deficiency.

(b) While a System Protection Warning is in effect, Customers

are required to minimize any variances between scheduled quantities and

actual flows. Customers are also required to minimize any imbalance

between receipts and deliveries. Deviations from scheduled quantities

or imbalances which benefit overall system operation will be permitted

without penalty.

up quantities which benefit overall system operations may be permitted
