El Paso said Thursday it had experienced an overnight rupture on Line 1102 just north of the Amarillo Compressor Station in the Texas Panhandle. The line was shut in between the Amarillo and Dumas stations for investigation, which required the additional shut-ins of one receipt point and three delivery points. El Paso declared a force majeure. Due to the isolation of Line 1102 in this area, the pipeline said, no gas can be scheduled from Plains to locations north of the Amarillo station. Also, delivery locations north of the station were required to adjust their supply sources in Cycle 3 nominations for Thursday’s gas day to one of three receipt points in the Anadarko Basin area. In an updated notice prompted by customer inquiries about whether gas moving south into Amarillo was affected as well as gas moving north from the station, El Paso clarified that it is unable to schedule any gas in either direction through the rupture area.

Southern California Gas declared a high-linepack OFO for Friday, saying it will assess Buy-Back charges in accordance with its tariffs to customers who deliver into its system more than 110% of their actual gas usage on the OFO day. In a related note, the giant LDC estimated that its storage fields will reach maximum capacity Friday, resulting in the loss of 400 MMcf/d in injection capability.

Citing “unseasonably warm weather (and as a result low market requirements)” in its service area, CIG said a Strained Operating Condition will take effect Friday until further notice. This condition is forecast to continue through the weekend and into the coming week, CIG said, and creates concern about its daily ability to handle imbalances that pack the system. It also “severely limits CIG’s ability to operationally accommodate storage injections in excess of each firm [customer’s] Available Daily Injection Quantity (ADIQ) or inventory levels above Maximum Available Capacity (MAC),” the pipeline added. See the bulletin board for further details.

Northern Natural Gas reported experiencing equipment failure at the Sunray Compressor Station in Texas and began unscheduled maintenance there Wednesday. During the station outage, which is expected to last through Nov. 13, flows at the BP Sunray Moore County receipt point will be limited to 40,000 MMBtu/d. Northern also reminded shippers on Matagorda Offshore Pipeline System (MOPS), which it operates, that an unexpected mechanical failure of the dehydration system at onshore MOPS facilities near Tivoli, TX, occurred last month (see Daily GPI, Oct. 22). The dehydration facility was repaired and put back into service, Northern said Friday, but a residual problem has resulted where high-moisture content gas is trapped downstream of the dehydration facility but upstream of six delivery points. This makes Northern unable to make any deliveries from MOPS to those points until further notice, the pipeline said.

Due to a possible leak, ANR said it is performing an unplanned pipeline inspection on its 747 Line that required the shut-in of five locations offshore Louisiana until further notice. ANR also lifted all restrictions at its Custer City location (see Daily GPI, Oct. 26).

Northwest reported experiencing compression issues in the Columbia River Gorge area, which has reduced available capacity at Roosevelt Compressor Station to 500,000 Dth/d. Northwest said it expects that full design capacity may be restored next week. Meanwhile it will continue to allow alternate nominations at Roosevelt as long as the total throughput does not exceed 500,000 Dth/d. If primary nominations increase enough to exceed that level, a deficiency period may be declared, Northwest said.
