Due to a leak on Coronado Pipeline, Dominion ceased deliveries to Columbia Gas at Cassity Mountain Wednesday. Dominion said it hopes to resume deliveries by June 30. All producers feeding directly into Coronado must shut in, Dominion said, and all producer compression in bubbles 4202, 4203 and 4205 on its system must be shut in until further notice. However, pool operators should not reduce their nominations during this outage, it added.

The Sea Robin Processing Plant got back on-line and began processing gas around 6:20 p.m. CDT Wednesday, Sea Robin Pipeline said. “Due to changing system conditions, plant processing may be impacted,” the pipeline said.

Due to heavy rain in the area, the end date for the ongoing outage on the discharge side of Texas Eastern‘s Circleville (OH) Compressor Station has slipped. The outage is now estimated to extend until Monday. It is the second rain-caused delay in completing the work (see Daily GPI, June 9).

Noting that it has been performing maintenance on the Sharon-Carthage section of its system during June, TGT said an additional project scheduled for Monday through Friday of next week will further reduce the section’s capacity. Volumes through the Haughton and Sharon Compressor Stations in North Louisiana will be cut to 175,000 MMBtu/d and 200,000 MMBtu/d respectively. Based on current nominations, TGT anticipates that no interruptible or secondary nominations will be scheduled and only a portion of nominations at primary firm receipt points will be scheduled.

Northern Natural Gas has scheduled July 8-14 maintenance on its East Leg at the Galena (IL) Compressor Station and along the downstream mainline. Mainline pressure reductions are required to facilitate the excavation, welding and tie-in activities, and Northern expects a curtailment of subscribed primary firm capacity at delivery points east of Galena. Volume reductions of 75,000 MMBtu/d or 140,000 MMBtu/d will occur each day of the work; see the bulletin board for details.
