A day after lifting an Imbalance Warning on Line 300 downstream of Station 313, Tennessee cited mild weather and limited operational flexibility in saying it will implement a systemwide Imbalance Warning Saturday. It will require all delivery point operators to keep actual daily takes out of the system equal to or greater than scheduled quantities regardless of their cumulative imbalance position, and all receipt point operators to keep actual daily receipts into the system equal to or less than scheduled quantities regardless of their cumulative imbalance position.

Saying its storage inventories are at high levels for this point in the injection season, CIG said a Strained Operating Condition (SOC) will take effect Friday until further notice. “During the effective period of the SOC, shippers should anticipate that CIG will require all transportation transactions to be in balance between receipts and deliveries.” Interruptible storage injections will not be available, CIG said. See the bulletin board for other SOC restrictions.

Although Destin planned to lift a force majeure Friday because the Pascagoula Gas Plant had resumed processing (see Daily GPI, Sept. 22), due to high liquids levels in its offshore segment, the pipeline said Thursday it will not yet be able to provide transportation services from offshore receipt points through the plant. A new force majeure event will be effective Saturday, Destin said, but it is anticipated that the process of removing liquids will not take longer than 24 hours, and when that is completed it expects to end the latest force majeure and resume deliveries to the plant. Meanwhile, an alternate delivery point at Viosca Knoll Gathering System will be available for all shippers with offshore production.

NGPL reported completion of a pipe replacement project on the Gulf Coast #1 mainline in its TexOk zone between Compressor Station 303 in Angelina County, TX, and Compressor Station 304 in Harrison County, TX, and said the GMT Rusk receipt point (maximum capacity of 1,000 Dth/d) became available for service again Thursday.

Questar said the installation of pigging facilities its ML 23 23/65 segment will not be completed until Friday afternoon, but it was allowing nominations at affected points in all cycles for Friday’s gas day and would notify producers to begin flowing gas as soon as the work is completed.

Enogex said a postponed Line 20 smart pigging operation is now scheduled for Oct. 5-10. “This outage will result in significant delivery allocations and will potentially impact all the East Zone delivery points,” Enogex said (see the bulletin board for a list). It is anticipated that up to 20% of firm Maximum Daily Quantities may be curtailed, “while nominations on interruptible transportation agreements may see significant allocations.”
