Pacific Gas & Electric declared a systemwide Stage 2 high-inventory OFO for Wednesday. The order carries $1/Dth penalties and has zero tolerance for positive daily imbalances.

Citing a force majeure event (lightning damage) at Compressor Station 601 in Logan County, CO, Trailblazer curtailed service through the station Monday down to the projected throughput. IT, Authorized Overrun and Secondary Firm services are unavailable there, and volumes of Primary firm shippers are being curtailed pro rata based on contract MDQ (maximum daily quantity). Repairs began Tuesday. Trailblazer anticipates that full capacity won’t become available again before Thursday “at the earliest.” Shippers will be informed as soon as possible if it is determined that curtailments will continue longer than anticipated.

Tennessee reported completion of repairs on a valve leak discovered last week at its East Cameron 49B compressor platform (see Daily GPI, Aug. 1). Nomination increases were being accepted Monday at 13 meters where physical flow was suspended during the repairs. The pipeline also announced a delay in its 526A-600 valve relocation project. Originally scheduled for Aug. 15-22, the project has been postponed to Sept. 4-15. Physical flow will be suspended at 17 meters during this maintenance. See the bulletin board for details.

About 22,000 MMBtu/d of flow was restored Saturday at the Matagorda 703/704/709 receipt point on Matagorda Offshore Pipeline System (MOPS). MOPS Platform 703 was shut down last month after a leak was discovered on a nearby 16-inch lateral (see Daily GPI, July 23).

El Paso will take Williams Station’s 5B compressor down for leak repairs Wednesday and Thursday. In combination with other maintenance already scheduled, this outage will cut North Mainline capacity by 140 MMcf/d Wednesday and by 215 MMcf/d Thursday. White Rock Station’s #2 turbine will be down for maintenance Aug. 19-20, reducing San Juan Basin capacity by 250 MMcf/d. The work will coincide with North Mainline maintenance already scheduled for those dates.

Tennessee added (contract number in parentheses) Kentucky Utilities (7514) and affiliate El Paso Merchant Energy (29693) to a list of shippers subject to daily variance charges if they violate the pipeline’s variance tolerance, which is the greater of plus-or-minus 10% of scheduled volumes or plus-or-minus 1,000 dekatherms. The two companies join 15 others previously posted (see Daily GPI, Aug. 2 and July 30). The pipeline said Amerada Hess (80101) will become subject to the charges Thursday.
