Preventative

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.
