While repairing an equipment failure at the Castle Valley CO2 Plant, Questar decided to inspect and repair additional equipment as a preventative measure. To facilitate the work, a plant outage originally scheduled for Feb. 11-12 will be extended through Feb. 13-14. The plant is expected to return to service at a reduced processing level of about 70,000 Dth/d for the Feb. 15 gas day. Because no processing will be available during the Feb. 11-14 period, Questar will work closely with upstream producers to maintain gas quality within tariff specifications. Equipment removed during the shutdown is scheduled for reinstallation during the last week of February, after which the plant is expected to return to normal service. No plant shutdown is required and no customer impact is expected during this installation, Questar said.

As a result of completing maintenance on the Seligman Station’s C turbine (see Daily GPI, Jan. 30) ahead of schedule, El Paso raised capacity of the North Mainline by 110 MMcf/d effective with nominations for Wednesday’s Cycle 4 and Thursday’s Cycle 2.

NGPL will take Compressor Station 302 in Montgomery County, TX out of service Feb. 4-10 for maintenance (it expanded the project’s originally planned scope of three days to seven days). During the outage NGPL’s ability to move gas into the Louisiana Line (Segments 25, 23 and 24) will be limited. Based on the current level of nominations on the Louisiana Line, ITS/AOR and Secondary out-of-path FTS transportation will be at an increased risk of not getting fully scheduled, the pipeline said. No impact on Primary FTS transportation is expected but it will have a slight risk should the level of nominations and/or the mix of receipt and delivery points on the Louisiana Line change significantly.
