18.1 General


Transporter may issue OFOs to preserve the integrity of

Transporter's Pipeline Facilities, to ensure adequate

operating pressures, to have adequate supplies in the

Pipeline Facilities, to assure adequate Transporter's Use

Transporter is unable to identify discrete Shipper(s) whose

action(s) require issuance of an OFO, any OFO will be

applicable to all Shippers on the affected pipeline

deliver Scheduled Quantities of Gas;


(b) a Shipper fails to maintain receipts or deliveries as

required in this tariff;
