(a) Prior to issuing an OFO, identify those imbalances which

adversely affect system line pack and resolve those

(c) Advise Shippers when Transporter considers that an OFO is

likely to be needed;

(d) Prior to issuing a system wide OFO, identify those

Shipper(s) whose current or pending imbalances contribute to

the need to issue an OFO and issue an OFO to those specific

Shippers; and

(e) Issue a system wide OFO to all Shippers on a not unduly

discriminatory basis.
