Re: System Imbalance Notice

Please be advised that Transco has been experiencing excessive
negative transportation imbalances (deliveries in excess of
receipts) on its system throughout the month.  Effective
immediately, shippers are advised to avoid any additional
negative imbalances and return to a balanced position.  Absent
voluntary compliance, it may become necessary for Transco to
suspend make-up deliveries for the remainder of the month.

Additionally, effective October 26, 2001 and until further
notice, Transco will institute more restrictive practices at its
pooling points.  Transco will reduce the 4% tolerance currently
allowed at its pooling points to 1% or 1,000 dts for Shippers
with negatively scheduled imbalances (i.e. deliveries into the
pools are less than receipts away from the pools).  Shippers with
positively scheduled imbalances at their pools will be held to
the 4% tolerance levels. Transco will not enforce these pool
imbalance tolerances during the timely nomination cycle; however,
Shippers are expected to balance their pools to the limits
identified above by the ID2 nomination cycle.  Transco may
proactively decrease markets to bring them in line with supplies
at pooling points.

If you have any questions, please call Terry Fitch at (713) 215-
3361 or John McGrath at (713) 215-2514.
