GENERAL TERMS AND CONDITIONS

Section 2

(Continued)

(b) Gulf South may post more restrictive gas quality

specifications, but in no event lower than the applicable

Safe Harbor limits, on its Internet Web Site as necessary

in order to alleviate an actual or anticipated operational

or engineering problem, to ensure the safe operation of

Gulf South's system, or to assure that gas will be accepted

for delivery by an on-system end-user, on-system

distributor, or downstream interconnecting pipeline. Safe

Harbor limits include: Sections 2.1(c) (carbon dioxide -

2.0% by volume), 2.1(k)(iii) (heating value - 1075 Btu/cf),

and 2.1(l) (hexanes and heavier hydrocarbons - 0.07 mole

percent). Postings will be based upon:

(i) Operational or engineering considerations,

including requirements to ensure the safe

operation of Gulf South's system;

(ii) Notification by an on-system end-user or an on-

system distributor of carbon dioxide, heating

value, or Hydrocarbon Dew Point / hydrocarbon

liquid problems at its facilities; and/or

(iii) Notification (either oral, written, or via

informational posting) that a downstream

interconnecting pipeline is experiencing or

anticipates a gas quality problem and may

impose more restrictive gas quality

specifications at interconnecting facilities

with respect to carbon dioxide, heating value,

or Hydrocarbon Dew Point / hydrocarbon liquid,

such that gas delivered from Gulf South may not

satisfy the interconnecting pipeline's gas

quality specifications and may not be accepted

by the interconnecting pipeline.

For gas quality specification postings issued

under section 2.2 in response to the

notifications listed above or as the result of

operational, engineering, or safety concerns on

Gulf South's system, Gulf South will provide

the maximum notice practicable; however,

parties will be given at least 48 hours to

comply with such postings.
