GENERAL TERMS AND CONDITIONS

Section 2

(Continued)

(l) Hexanes and Heavier Hydrocarbons - The hydrocarbon liquid

content shall not contain more than 0.21 mole percent of

hexanes and heavier hydrocarbons ("C6+ Limit"). Pursuant

to Section 2.2(a), (b), and (c), Gulf South may post on its

Internet Web Site, for the entire system or by specific

operational area(s), a C6+ Limit less than 0.21 mole

percent; provided, however, that such posted C6+ Limit

shall not be less than 0.07 mole percent, which is the

approximate equivalent of a 15 degree Fahrenheit

Hydrocarbon Dew Point.

2.2 (a) If Gulf South experiences or anticipates operational,

engineering, or safety problems on its system related to

carbon dioxide, heating value, or Hydrocarbon Dew Point /

hydrocarbon liquids, or becomes aware that an on-system

end-user, on-system distributor, or downstream

interconnecting pipeline is experiencing or anticipates

such gas quality problems and may not accept gas delivered

from Gulf South's system, then Gulf South will take the

steps below, in the following order when practicable:

(i) Gulf South will terminate or suspend gas quality

waivers granted pursuant to Section 2.3 (b) by

specific operational area(s) determined by Gulf South

to contribute to a specific problem; and

(ii) Subject to Section 2.2(b), Gulf South may post on its

Internet Web Site more restrictive gas quality

specification limits, but in no event lower than the

applicable Safe Harbor, for carbon dioxide, heating

value, or hexanes and heavier hydrocarbons to assist

in the management of such problems by specific

operational area(s).

When managing gas quality problems, any posting of a more

restrictive specification will be limited to addressing

only problems arising with respect to that particular

specification. For example, Gulf South will not post a

notice to lower the maximum Btu limit for the purpose of

addressing a hydrocarbon liquids problem.
