gum-forming constituents and other solid matter.

(h) HEATING VALUE

The gas delivered shall contain a daily, monthly

and yearly average heating content of not less than nine hundred fifty

(950) Btus per cubic foot. In addition, Natural may, from time to time,

as operationally necessary, establish and post on the Informational

Postings portion of its Interactive Website an upper Btu/cf limit and/or

a limit on the dewpoint for receipts on specified segments or other

specified locations on its system to prevent hydrocarbon fallout,

consistent with Section 26.1(f) hereof, or to assure that gas will be

accepted for delivery into interconnects with interstate pipelines,

companies. Natural will include in such posting the anticipated duration

of the limitation. Points with an actual flow of 100 Dth/d or less will

be exempt from the limitation in any such posting. Natural will provide

as much prior notice as reasonably practicable and will attempt to

provide in the posting at least two (2) Business Days' prior notice

the posting why it was unable to give such prior notice. Where the

posting includes a dewpoint limitation, Natural will, upon request,

provide current information regarding the dewpoint at any point of

receipt into Natural's system affected by the posting to the operator of

that point or any producer, purchaser, supply aggregator or Shipper with

gas being tendered at that point.
