engineering and operating constraints, and for maintenance of

service at projected levels to all Shippers, consistent with

applicable priorities of service. The Operating Plan may include,

inter alia, a specification of:


(i) Desired levels of flow gas for each

category of Shipper during various periods of the year.


(ii) Plans to deal with specific contingencies

Horizon anticipates may occur during the period covered by the

Operating Plan.


(b) The Operating Plan shall be for planning and

informational purposes only and shall not be binding on Horizon or

on any Shipper. It is further understood that, since all elements

of an Operating Plan are subject to continual change and are

contingent on the actions of numerous Shippers, the Operating Plan

may not necessarily be an accurate depiction of Horizon's system

at any point in time.


(c) Horizon may request that Shippers periodically

provide non-binding estimates of flow patterns and other operating

parameters. Such information may be used by Horizon in

preparation of the Operating Plan or in testing whether an

Operating Plan previously circulated requires revision.




In the event Horizon's observations or projections

indicate that a situation is or may be developing in which

adequate pressures may not be maintained or the overall

operational integrity of its system (or any portion thereof) could

be threatened, or in the event that such a situation actually

occurs, Horizon is empowered by this Section to take action to

alleviate this situation. In responding to such a situation,

Horizon shall first apply the Advisory Action procedures of

Section 34.5. If such measures are not sufficient to address the

situation fully, Horizon shall next employ Operational Flow Orders

as provided in Section 34.6. In the event Operational Flow Orders

alone are not adequate, Horizon may invoke the Critical Time
