Southern California Gas kept a high-linepack OFO that it had implemented Friday in effect through Monday before lifting it Tuesday.

Pacific Gas & Electric allowed a systemwide high-inventory OFO to expire Sunday after it had been in effect for three days.

Westcoast told shippers and producers who use the McMahon Gas Plant that it will take the 10-inch diameter Tommy Lakes Pipeline out of service for 36 hours starting Wednesday morning to repair the pig-sending barrel isolation valve. Westcoast said it will shut in all receipt points on the line and depressure the entire length of the pipeline.

NOVA said it will begin pipe maintenance Thursday morning in Segment 1 on the 20-inch diameter Peace River Mainline upstream of Dryden Compressor Station. The work, which is expected to last until the morning of June 4, will cause a reduction to 61% of allowed Firm service at 17 pints in the area, NOVA said.

Repairs of an exhaust leak on Williams Station's C unit were finished on schedule and an associated 200 MMcf/d reduction of North Mainline capacity was lifted for Friday's Cycle 3 nominations, El Paso said. Checks of the Williams B unit are continuing and a 32 MMcf/d cut of North Mainline capacity will remain in effect until further notice.
