NGPL reported a force majeure event that occurred Monday between Stations 106 and 196 in Gage County, NE, and impacted both of NGPL’s mainlines through the area. Due to heavy rains in the area, an ongoing maintenance project’s excavation has been flooded, NGPL said, and for safety reasons it immediately reduced the pressure and flows through the affected lines. In an update Tuesday, the pipeline said work is ongoing at the site to remove the water surrounding the pipelines, and inspections will take place once the water is removed. NGPL did not make any intraday scheduling reductions Monday, but said effective Tuesday until further notice, ITS/AOR and Secondary out-of-path transports through the area will not be available. Additionally, firm Primary and Secondary in-path transports are at risk of not being fully scheduled. See the bulletin board for further details.

El Paso said it has determined that a pipe anomaly between the Eunice and Pecos River Stations will require replacement of about 80 feet of pipe, which will begin at 8 a.m. MST Thursday and is expected to take 12 hours. The reduction in segment capacity will be about 200 MMcf/d out of a base capacity of 400 MMcf/d. The IPENNWELL interconnect will be completely shut in for the duration of the work, but based on current levels of throughput, El Paso expects minimal service impact.

Hill and Custer Compressor Stations in the Southwest Gathering Area to 200 MMcf/d Wednesday. “At this time, it is anticipated this restriction will be in place through the weekend or until more information becomes available,” ANR said. Based on recent nominations, it expected that the reduction would result in the curtailment of nominations associated with IT and Firm Catalog Receipt Points in the affected area.
