Algonquin Gas Transmission (AGT) will be conducting Department of Transportation-mandated pipeline investigations on its G-System through gas day May 22. During these investigations AGT will be required to lower its operating pressure on the G-system to 575 psig. The pipeline said customers/point operators should be aware of the impact of nonratable takes from the system, which may cause delivery pressures to reach lower than desired levels. Accordingly, AGT requests that customers/point operators in this region minimize nonratable take patterns during this outage.

Due to the previously posted pipeline maintenance between Longview and Atlanta, Texas Eastern restricted interruptible nominations sourced in the ETX zone for delivery outside that area for gas day Tuesday. No increases in receipts between Huntsville and Little Rock for delivery outside that area will be accepted.

Gulf South Pipeline will be performing pigging maintenance on Index 8-18 beginning May 17 and continuing for approximately 30 days. Due to the nature of the pigging maintenance shut-in at various farm tap locations and one wellhead location will occur for two to five days during the maintenance. The pipeline said the Gaston Trust #1 will also be shut-in by the subject pigging maintenance beginning May 19 for two to three days.

Based on projected market area loads, expected flows from Demarc, and carbon dioxide (CO2) levels at the Trailblazer interconnect (POI 1318), Northern Natural Gas said it expects to schedule between 200,000 and 350,000 Dth/d at the Trailblazer interconnect until further notice. Volumes are being allocated at the Trailblazer interconnect due to less gas being received from receipt points south of Beatrice that provide the ability to blend CO2 from Trailblazer to acceptable levels on Northern’s system but are subject to change depending on the quantity and location of gas scheduled in the market area. Within this range, Northern said it may be able to schedule a higher level of volume during the week with lower levels on the weekends due to anticipated lower market throughput levels.

Williams’ Northwest Pipeline said Burley compressor station maintenance will reduce Rockies north flowing gas by 54,000 Dth/day effective Tuesday through Friday. This reduction is in addition to the Soda Spring pig run reduction of 68,000 Dth/d.
