Due to an outage downstream of the Tracy City Compressor Station and in order to maintain its operational integrity, East Tennessee Natural Gas will implement a Balancing Alert OFO effective Tuesday for LMSMA parties with meters between Tracy City and the Topside location.

See the bulletin board for a list of affected meters.

Southern California Gas regained a total of 340 MMcf/d of receipt capacity Monday at the Topock border interconnects with both Transwestern and El Paso after completing work two days earlier than expected on Line 3000 from Main Line Valve 1 to Newberry Compressor Station.

Gulf South plans two days of pipe maintenance starting Nov. 1 on its Index 176 (30-inch diameter Garden City Plant Line), during which the Nautilus (from Nautilus) and Centerville (from Trunkline) receipt points will be unavailable for service.

Sea Robin Pipeline‘s Erath Compressor Station was shut in Monday due to unplanned maintenance on a unit. Columbia Gulf and Jefferson Island will be the only delivery points physically available for nominations during the outage, Sea Robin said; all other high-pressure delivery points downstream of Erath must remain shut in until further notice. The Hess-operated Sea Robin Gas Processing Plant is currently processing, the pipeline added, but if nominations fall below the required minimum to process, Plant Volume Reduction/Plant Thermal Reduction nominations will no longer be accepted, although Hess will continue to dehydrate. In addition, due to the combined effect of the Erath Compressor Station outage and the reduced maximum allowable operating pressure of 984 psig on Sea Robin’s West Leg, IT nominations from 19 West Leg receipt points (see the bulletin board for a list) will not be accepted during the outage.
