Northwest ended on Wednesday morning a Declared Deficiency Period that it had issued late Tuesday afternoon in connection with emergency repairs to the #2 unit at La Plata Compressor Station. Northwest had said it would cut scheduled volumes through the station to 250,000 Dth/d in the Intraday 2 nominations process for Tuesday’s gas day, but would wait until the Intraday 2 process Wednesday before cutting volumes scheduled for that gas day in the hope that repairs could be completed by midday.

Under a new daily Interconnect Imbalance Management process (see the bulletin board for details), CIG said it was placing an underperformance cap on its Horse Trap receipt point for Cycle 3 nominations Tuesday and Cycle 1 nominations for Wednesday’s gas day. “This will impact shipper nominations,” the pipeline said. And due to a Laramie Compressor Station unit outage causing increased pressures at Green River NPC Station 6, CIG said it reduced operating capacity at Green River to zero in Cycle 2 nominations for Wednesday’s gas day. “As the situation continues, we may have to make additional reductions at other points along the Wyoming Mainline,” CIG said.

ANR said Wednesday it must begin unplanned engine repairs at St. John Compressor Station in Indiana, located in the Northern Fuel Segment (ML-7). Total St. John west-to-east capacity will be reduced by 115 MMcf/d (leaving 1,190 MMcf/d available) Thursday. Based on current nominations along the Michigan Legs, the reduction likely will result in the curtailment of IT and Firm Secondary nominations, ANR said. And the pipeline has begun unplanned engine repairs at Sandwich Compressor Station in Illinois, also in the Northern Fuel Segment. Effective with the start of Thursday’s gas day, ANR anticipates that only Firm Primary nominations will be scheduled through the Sandwich East-CFTP location. This operational restriction is expected to continue through Aug. 3.
