Southern California Gas declared a high-linepack OFO for Saturday and Sunday with 10% tolerance for positive daily imbalances, then allowed it to lapse Monday.

Pacific Gas & Electric did not extend a systemwide high-inventory OFO beyond Friday.

Dominion will replace a section of its TL-275 line Thursday, requiring that all production in bubbles 2303 and 2304 except gas flowing into H-17837 from Pond Fork and Skin Fork must be shut in by the start of the gas day. Barring unforeseen circumstances, flows may be resumed at 4 p.m. that day, but producers must check with pipeline field personnel beforehand, Dominion said.

ANR has begun engine maintenance at Bridgman Compressor Station in Michigan and at St. John Compressor Station in Indiana, both in the Northern Fuel Segment (ML-7). The work is reducing total St. John west-to-east capacity by 115 MMcf/d (leaving 1,190 MMcf/d available) through April 19 and by 40 MMcf/d (leaving 1,265 MMcf/d available) from April 20 through May 11. Based on current nominations along the Michigan Legs, it is anticipated that the above reductions will result in the curtailment of IT and Firm Secondary nominations, ANR said Monday.

El Paso said the Mojave Topock Station will be down for about five hours at the start of Tuesday's gas day for Department of Transportation-mandated emergency shutdown testing. Two units should then be available for the rest of the gas day, El Paso said. From a base of 500 MMcf/d, it estimated the effective capacity reduction Tuesday to be 170 MMcf/d.

As previously posted, Southern Natural Gas has scheduled shut-in tests at its two storage fields this month. Testing will begin Tuesday at the Bear Creek Storage Facility in North Louisiana and continue through April 16. The Muldon Storage Facility in Mississippi is scheduled for April 24-30 testing. See the bulletin board for customer requirements during the tests.
