Citing the continuing interruption of Gulf of Mexico supplies caused by Hurricane Katrina and warm weather in Florida, Gulfstream said Thursday an OFO that it had initiated Tuesday will remain in effect until further notice. See the bulletin board for the OFO’s conditions.

Florida Gas Transmission extended an Overage Alert Day notice for its market area through at least Thursday, but further loosened the tolerance for negative daily imbalances from 10% to 15%.

Tennessee said Thursday it has determined that in addition to the meters on its Bluewater Header (from Vermilion 245 to Ship Shoal 198) being available again after hurricane-related shut-ins, 19 meters on TTT Line 523M-2300 (from Eugene Island 365 to Ship Shoal 198) are now available. But it reminded shippers that Mainline Valve 528 remains shut in due to high water at the Port Sulphur Compressor Station (Station 527) in South Louisiana. Tennessee required all operators and producers located upstream of this facility to keep their physical flow and scheduled volumes at zero until further notice except for meters that had been posted as operational.

El Paso said operating conditions on its South Mainline have improved since it warned Monday of a possible Strained Operating Condition declaration. “Customer response has been sufficient to raise [El Paso] linepack to acceptable levels and to discontinue withdrawal from the Washington Ranch storage facility,” the pipeline said. It encouraged shippers with due-pipeline imbalances to initiate payback to help restore storage inventory.
