GENERAL TERMS AND CONDITIONS

----------------------------

 

(g) DUST, GUM AND SOLID MATTER

 

The gas shall be commercially free of dust, gum,

gum-forming constituents and other solid matter.

 

(h) HYDROCARBON DEWPOINT

 

(1) Natural may, from time to time, as

operationally necessary, establish and post on the Informational Postings

portion of its Interactive Website an upper 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.

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 of any such limitation as reasonably practicable and

will attempt to provide this prior notice in the posting at least ten (10)

Days before the beginning of the month in which the limitation is to be

effective. If prior notice by posting at least ten (10) Days before the

beginning of the month is not practicable, Natural will explain the reason

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

 

(2) Notwithstanding the foregoing, Natural may not

decline to accept gas based on its dewpoint if the dewpoint of that gas is

equal to or less than fifteen degrees Fahrenheit (15 F.) In addition,

Natural shall continuously post "safe harbor" dewpoint values based on

operational and engineering considerations and shall make any changes in

these "safe harbor" values effective no sooner than 30 days after the

revised "safe harbor" values have been posted. Natural may not decline to

accept gas which conforms to such posted "safe harbor" values if the gas

meets the other quality standards set out in this Section 26. No such

posting may set out a dewpoint "safe harbor" of less than fifteen degrees

Fahrenheit (15 F).

 

(3) Where any posting of a limitation under Section

26.1(h)(1) includes a dewpoint limitation, Natural will calculate the

dewpoint at any point of receipt into Natural's system affected by the

posting on request of the operator of that point or any producer,

purchaser, supply aggregator or Shipper with gas being tendered at that

point.

 

(4) Natural shall post on its Interactive Website,

within twenty-four (24) hours after making the calculations, the

following: every receipt point dewpoint value Natural calculates, along

with the method by which the dewpoint was calculated; and every blended

dewpoint Natural calculates for a line segment of its system.
