OK, Force Majeure ended Sept 27
Western LA facilities shut-in
Force Majeure, effective immediately for meters upstream of and including the Egan
Measurement Stations due to high water at and around the Pecan Island compressor and
Separation Station resulting from Hurricane Rita. CGT requires all operators and producers
located upstream of this facility to keep physical flow and scheduled volumes at zero until
further notice.
Shut-in since Sept 20
CIPCO has minor damage and Black Lake remains shut-in due to lack of supplies; note that
most of company’s natural gas assets are in Oklahoma and West TX and are not adversely
affected.
The Texas Eastern pipeline is in balance and holding pressure. Most compressor stations and
storage facilities affected by Rita are back on-line. The Gulfstream natural gas system is
operational.


No nominations until further notice; Stingray has flooding and wind damage to onshore
facilities; Sea Robin delivery point damaged.


Shut-in after completion of Schedule Day Cycle 1, September 23, 2005 (Flow Day beginning
September 24, 2005) until further notice.
May be required to schedule only primary firm capacity and implement scheduling reductions
for the September 29 Gas Day and Nomination Cycle.
Force Majeure continues on Border, Texas, North Texas, and Tejas pipelines; Natural Gas
Pipeline Company of America declared Force Majeure on parts of Segment 16 (Arkoma), 23
(TGT Lowry), 24 (Col Erath, Equitable, GS Erath, and LRC) , and 26 (Sabine). Sabine Force
Majeure continues in effect at all points on the Sabine system. Power remains out in most
areas of the system. Efforts are underway to remove standing water from Sabine's Henry
facilities.
Trunkline's Terrebonne System is accepting nominations for gas on starting today Sept 27.
Some receipt and delivery points are not available. 28 receipt points are now cleared for flow,
up from 17. Trunkline LNG, in Lake Charles, LA, remains shut down. Florida Gas
Transmission fully operational. Sea Robin has damage at its delivery point; it is not accepting
nominations.
Tennessee is lifting the system wide OFO Balancing Alert effective immediately. However,
Tennessee reminds customers to flow scheduled volumes to avoid the necessity of issuing an
Operational Flow Order in accordance with tariff provisions. Tennessee has identified several
leaks and instances of flooding that will limit the operational flexibility of its system. There are
also several points that remain shut in due to Force Majeure declarations on other pipelines.


Most Williams facilities are returning toservice. The Transco and Gulfstream natural gas
pipeline systems have remained operational throughout hurricanes Rita and Katrina, although
volumes were reduced on both systems because of producers’ storm related supply shut-ins.
Transco is experiencing continued power outages and other storm related logistics in
Louisiana, specifically in the Lake Charles and Eunice areas. Nominations will not be
accepted on the Southeast Louisiana Lateral due to damage to Transco and 3rd party
facilities as a result of Hurricane Rita. The pre-hurricane volume from these locations that will
be impacted is approximately 80 MMcf/d. Black Marlin offshore pipeline is now operational
and ready for gas as of Sept 26; The only report of significant damage so far is at the
company’s Cameron Meadows natural gas processing plant near Johnson Bayou, LA.
