1. DEFINITIONS (Continued)


o An "Operational Flow Order" (OFO) shall be an order issued to

alleviate conditions, inter alia, which threaten or could

threaten the safe operations or system integrity of Company's

system or to maintain operations required to provide

efficient and reliable service. Whenever Company experiences

these conditions, any pertinent order shall be referred to as

an OFO. Company shall attempt to minimize the use of OFO's

and the declaration of critical periods and, when possible,

shall direct an OFO to the specific party(s) creating the

operating conditions. The declaration to the affected

parties of OFO's, critical periods, and/or critical notices

shall describe the conditions and the specific responses

required from the affected parties. Notice procedures of OFO

conditions shall be clearly defined in Company's tariff.
