Saying it has experienced declining linepack as a result of customer takes that exceeded their scheduled receipt volumes, particularly on its southern system, El Paso declared a Strained Operating Condition (SOC) with an imbalance threshold of 4% Tuesday. The Washington Ranch Storage facility has been operating at maximum withdrawal capacity recently and linepack continues to drop, the pipeline said. It added that the SOC applies to the smallest possible area of its system and includes the following parties with takes on the South Mainline: Arizona Public Service, Salt River Project, Duke Energy Arlington Valley and El Paso Electric (not affiliated with the pipeline). In an earlier posting Tuesday warning of the SOC possibility, El Paso urged shippers to match their demand requirements with current supplies and to schedule payback of existing imbalances to the pipeline, if possible. It also said shippers can obtain supplies at Waha where capacity is operationally available, and that limited amounts of capacity may be available at the Keystone pool and from San Juan Basin.
NOVA lifted the restrictions on its 18-inch diameter Gold Creek Lateral at 8 p.m. MDT Monday, restoring all services at six affected stations (see Daily GPI, Aug. 23).
Gulf South said Monday it was performing unscheduled maintenance at its Olla (LA) and Jackson (MS) Compressor Stations until further notice. Capacity through the stations could be affected by as much as 150 MMcf/d and 125 MMcf/d respectively, the pipeline said.
Due to maintenance, TGT will reduce operational capacity through its Haughton (LA) Compressor Station to about 200,000 MMBtu/d Wednesday.
