Citing forecasts of warmer weather in Florida and low linepack levels, Florida Gas Transmission issued an Overage Alert Day for market-area customers Thursday that carried a 25% tolerance for negative daily imbalances.

Southern California Gas and Pacific Gas & Electric did not extend their high-linepack OFOs beyond Thursday. SoCalGas also said it began a “high-inventory shut-in” for well verification Thursday at its Honor Ranch storage facility. The shut-in, which is expected to last through Nov. 12, is causing the loss of 250 MMcf/d and 1,000 MMcf/d of injection and withdrawal capacity, respectively, the LDC said.

In its latest update on a lingering partial system outage caused by a mid-September compressor station fire, Cheyenne Plains estimated that its compression and processing facilities will be available again sometime during the coming week. While again cautioning that a definitive date for return to service depends on several factors, the pipeline said its repair of damage to instrumentation and electrical wiring continues to go well and it does not anticipate finding any additional damage or receiving new adverse information from its investigative team.

Due to a force majeure situation involving a leak on Line P, Columbia Gas required all production at certain points (see the bulletin board for list) to shut in Thursday. It expected to complete leak repairs “on or about” Friday.

NGPL said FERC had approved its request to allow a waiver of its tariff to extend Opposite Leg Rights for affected shippers to all Gulf Coast receipt zones while a capacity reduction on its Illinois Lateral (see Daily GPI, Oct. 19) remains in effect. Effective Thursday until further notice, firm shippers on the Amarillo Line impacted by the lateral constraint can utilize all Gulf Coast receipt zones as alternate supply sources for deliveries to the Market Delivery Zone, NGPL said.

Southern Natural Gas reported earlier-than-expected completion of control valve repairs at the Main Pass 289 VK receipt point (see Daily GPI, Oct. 22) and resumed taking nominations there Thursday.

Northwest changed the schedule for a series of pig runs between the Rangely and Cisco compressor stations this month. Northwest said it was notified by the vendor that the caliper pig originally scheduled to be run on Nov. 20 is no longer available that day, and as a result the run is being moved up to Nov. 13. “This change will enable Northwest to complete this work in a shorter time period and avoid impacts to customers during the week of Thanksgiving,” the pipeline said. Available southbound capacity at Cisco will be limited to 138,000 Dth/d on Nov. 6, 13 and 16 and to 244,000 Dth/d on Nov. 7 and 9. Northwest said CIG had asked it to inform shippers that the Sand Springs receipt point will be shut in during the hours of the pig runs on those days; see the bulletin board for details.
