Tennessee lifted Tuesday the OFO Action Alert for Zone 4 that had been implemented Sunday, but said Zones 5 and 6 remain under the OFO Action Alert until further notice.

Southwest Gas said it declared a “hold to burn notice” Tuesday “due to consistent and repeated underpulls from transportation customers and requests from Southwest’s upstream pipelines to draft gas that has been banked over the last several days.” The notice will remain in effect until further notice.

Because unscheduled maintenance at Buckley Compressor Station has continued for longer than anticipated, CenterPoint said it is replacing an Operational Alert (OA) that was issued Jan. 14 and updated a day later. The updated OA will be terminated Sunday and the new OA will become effective at that time, CenterPoint said. “Attempts to temporarily repair the [Buckley] equipment have been unsuccessful, and [CenterPoint] anticipates that it will be winter 2009 before Buckley is operational again,” the pipeline said. See the bulletin board for operational conditions that will be in effect under the new OA.

Citing “a possible leak,” ANR shut in its Eugene Island 30 meter offshore Louisiana until further notice Monday while it performs unplanned pipeline maintenance. In addition, ANR said a continuing gas quality issue at its Ship Shoal 207/Enbridge interconnect had prompted it to further restrict capacity there to 70 MMcf/d Tuesday and to extend the duration of the restriction through the end of March. ANR had previously set the limit at 140 MMcf/d and expected to end it Saturday (see Daily GPI, Feb. 23).

Questar had scheduled a March 3-5 engine replacement on Unit #3 at Oak Spring Compressor Station. However, the pipeline postponed the project, saying it was notified by the vendor that delivery of the replacement engine has been postponed until late March. During the three days of work capacity of the ML 104 scheduling point will be reduced to 290,000 Dth/d, returning to 500,000 Dth/d when replacement is completed. “Normal hours on the engine are high enough to warrant routine replacement,” Questar said. It tentatively expects the work to take place during the week of March 23, and said it will post an updated message as soon as the dates are confirmed.

Westcoast will begin an outage of the Pine River Gas Plant’s “B” Train at the start of Wednesday’s gas day to complete inlet filtration valve replacements. “To ensure that all firm service customers have access to the system,” Westcoast said, it is activating a 75% Firm Raw Gas Treatment OPC Constraint until it completes the work, which is expected to take 14 hours.
