30. OPERATIONAL FLOW ORDER (OFO) PROCEDURES

30.1 GTN, in its sole discretion, will have the right to issue OFOs

when in its judgment it is necessary to maintain or restore the

operational integrity of its system.

30.2 Whenever possible, GTN will identify those Shipper(s) or OBA

Operator(s) whose action(s) require GTN to issue an OFO and will

limit the applicability of the OFO to such Shipper(s)/OBA

Operator(s). If GTN is unable to identify those Shipper(s)/OBA

Operator(s) whose action(s) require issuance of an OFO, or if

issuance of an OFO to discrete Shipper(s)/OBA Operator(s) is

insufficient to alleviate the conditions requiring the issuance of

such OFO, GTN may issue an additional OFO applicable to all

Shippers and OBA Operators on a nondiscriminatory basis.

30.3 All OFOs will be posted on GTN's website, to be followed by a

facsimile, written notice or other mutually agreeable means of

electronic communication to affected Shippers/OBA Operators that

will set forth the causes or conditions necessitating the OFO. GTN

will issue an OFO as expeditiously as is reasonable and practicable

in the circumstances. When practicable, GTN will provide

sufficient notice to shippers to accommodate scheduling

requirements on upstream pipelines. Each OFO will contain the

following provisions:

(a) time and date of issuance;

(b) time that the OFO is considered to be effective (if no time is

specified, the OFO will be effective immediately);

effective until further notice);

(d) the quantity of gas required to remedy the operational

condition requiring the issuance of the OFO; and

(e) any other term GTN may reasonably require to ensure the

effectiveness of the OFO.

GTN will post information, as soon as possible, about the status of

operational variables that will determine when an OFO will begin

and end. GTN will post a notice on its website informing

Shipper(s)/OBA Operator(s) when any OFO in effect will be canceled.

Following the issuance of an OFO, GTN will post information on the

factors that caused the OFO to be issued and then lifted as soon as

it is available.
