The Company will use the operating plans and Average Daily Contract Quantities as submitted with contracts by Customers receiving service hereunder, to determine the appropriate level of market based pricing for services required to manage the daily use of natural gas of the Customers receiving service under this rate schedule. Therefore, Customers should use due diligence to minimize daily variances between their projected and actual operating plans to ensure the best available pricing of their gas service under this Rate Schedule. During critical periods of operation on the Company's gas supply system or on its supplying pipelines, Customers may be limited to their daily operating plan. In the event that during a critical period the Customer takes gas in excess of its daily operating plan, the Company will, so far as practicable, undertake to proportionately allocate among its Customers gas supplies as may be available, otherwise, service in excess of the Customer's daily operating plan or available supplies will be deemed supplied under the provisions of Rate Schedule 331. The Company shall notify the Customer of the occurrence of such critical period and availability of supplies as far as practicable in advance of, and in any event not less than thirty (30) minutes before, the beginning or discontinuance of such critical period of operations on the Company's gas supply system or on its supplying pipelines. Customer's may not make further changes to their operating plans once the notification of the critical period has been made due to the limitations on the Company's supply system during these critical times.

This rate applies to gas having a monthly average total heating value of approximately 1,000 British thermal units (Btu) per cubic foot.
