Based upon mandatory evacuation orders issued by various governmental entities along the central Texas Gulf Coast, Texas Eastern said it will be required to shut in compression that is necessary to move gas out of the South Texas and East Texas zones. Effective at 6 p.m. Wednesday all IT-1 and a portion of secondary/preferential firm service was restricted for volumes sourced in those zones, the pipeline said. As information is received from supply interruptions, Texas Eastern will force balance TABS pools as required to maintain system reliability.

Due to Hurricane Rita, NGPL anticipates that several of its compressor stations will not be available or will not have full service because of either losing electric power or being under evacuation orders. The impacted locations are Station 302 in Montgomery County, TX; Station 343 in Liberty County, TX; and Station 342 in Cameron Parish, LA, NGPL said. “The unavailability of these compressors is a force majeure event due to personnel evacuation or other public safety concerns,” it added. Effective Thursday Segment 25 will have a reduction of available capacity, and NGPL will schedule primary firm and secondary-in-path capacity to 90.5% of the aggregate Segment 25 contract Primary MDQ [maximum daily quantity] for gas nominated through Station 302 for delivery into Segments 25, 23 or 24. ITS/AOR and secondary out-of-path transports will be unavailable, the pipeline said. Effective Friday and until further notice, Segment 25 is anticipated to have an additional reduction of available capacity, and NGPL therefore expects to schedule primary firm and secondary-in-path capacity on these days to a minimum of 60% for gas sourced as described above. This percentage could change as actual availability is known.

Due to experiencing low linepack levels “with receipts into the system being less than deliveries out of the system,” Gulfstream issued an Action Alert effective with the start of Wednesday’s gas day. See the bulletin board for the alert’s conditions.

In accordance with a request by Houston’s mayor, the Panhandle Energy building will be closed Thursday to all but essential personnel and completely Friday.

Gulf South plans to close its Houston offices at noon Thursday to everyone except for emergency personnel. The pipeline said it was suspending all nonessential processing, such as service request evaluations, until further notice. “Gulf South may modify its nomination procedures and timelines if operating conditions warrant such modification,” it said.

Tennessee reported being informed that the Grand Chenier Plant, Johnson Bayou Plant and Sabine Plant on its 800 Leg would be evacuated and their inlet valves closed Wednesday. Citing “significant production losses” on the 800 and 500 Legs and potential production losses on the 100 Leg, it adjusted receipts into and deliveries from all Supply Aggregation Pools to a tolerance of zero dekatherms.

Operator Northern Natural Gas said it planned to allocate scheduled volumes on the Matagorda Offshore Pipeline System (MOPS) due to shut-ins expected during the afternoon and evening Wednesday. of September 21, 2005. This is a potential force majeure situation, it said.

Citing production losses that were expected to grow, Transco initiated its Emergency Supply Allocation Process effective with the Intraday 1 nomination cycle for Thursday’s gas day and for all nomination cycles for Friday’s gas day and beyond until further notice. It urged all customers to update any schedule rankings applicable to their business “in order to prepare for any potential forced system balancing.”

Questar said an OFO will be in effect for Oct. 3-18 inventory testing at its Clay Basin Gas Storage Reservoir. No physical withdrawals will be allowed during the Oct. 3-10 period. A 200 MMcf/d physical injection test is scheduled for Oct. 11. Firm Storage customers will be required to inject their required pro-rata share of the injection volume as specified in individual OFO notices and must have sufficient working gas “space” in their respective accounts for the scheduled injection volume, Questar said. The reservoir will be shut in, with no nominations accepted, for the Oct. 12-18 gas days. Service is expected to return to normal Oct. 19.
