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) A schedule of desired storage injections and

withdrawals to maintain storage deliverability and protect the

integrity of Natural's reservoirs.


(iii) Plans to deal with specific contingencies

Natural 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 Natural 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 Natural's system at

any point in time.


(c) Natural may request that Shippers periodically

provide non-binding estimates of flow patterns, injections and

withdrawals and other operating parameters. Such information may be

used by Natural in preparation of the Operating Plan or in testing

whether an Operating Plan previously circulated requires revision.




In the event Natural'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, Natural is

empowered by this Section to take action to alleviate this

situation. In responding to such a situation, Natural shall first

apply the Advisory Action procedures of Section 23.5. If such

measures are not sufficient in Natural's judgment to address the

situation fully, Natural shall next employ Operational Flow Orders

as provided in Section 23.6. In the event Operational Flow Orders

alone are not adequate, Natural may invoke the Critical Time
