Pacific Gas & Electric did not extend a high-linepack OFO with zero tolerance for positive imbalances beyond Saturday.

Due to unexpected problems experienced over the weekend at the San Juan River Plant, capacity in El Paso’s San Juan Triangle has been reduced by 40 MMcf/d until further notice.

Effective today, NOVA is implementing Flow Orders on its Alberta system to manage short-term operational outages. The intent of Flow Orders is to identify for affected operators the maximum allowed flow rate through a pipeline interconnect for a specified period of time, NOVA said. It added that Flow Orders will be specifically used for (1) isolated single meter station work requiring a reduction in flow rate for up to eight hours; (2) taking meter stations to zero flow rate for any duration of time; or (3) extending a planned outage for up to two additional nomination cycles. Call Pat Blixt at (403) 920-5547 or Mike Mazier at -2651 for more information.

NHC has notified Panhandle Eastern that annual turnaround maintenance at the National Helium Plant near Liberal, KS will begin June 5 and is expected to be completed June 8. No processing or dehydration will occur during the work. The pipeline will conduct an emergency shutdown test June 6 of its Liberal Station and all upstream stations. An increase in system heating values will result from the plant outage, Panhandle said. Receipt points will be monitored for high water content and may be restricted during the outage.

Citing scheduled maintenance, Tennessee did not accept any nominations for today at its Dracut, MA interconnect with Maritimes & Northeast.

Gulf South said Monday unscheduled maintenance has been completed at its Goodrich and Edna compressor stations in Texas and that West 30-inch line (Index 129) capacity was restored to normal.

El Paso said there will be a 450 MMcf/d cut in San Juan Basin supply availability June 4-7 due to producers’ maintenance. The pipeline will perform maintenance at downstream locations during those dates to minimize additional impact. White Rock Station will be down for annual Department of Transportation inspection June 4-5, reducing San Juan capacity by 230 MMcf/d but causing no added impact to that mentioned above. Line 1300 on the San Juan Crossover will be shut in for piping modifications June 4-6, resulting in no flow from San Juan east for delivery to the South Mainline, Waha or Anadarko. Line 1212 between Valve 4 and Gallup Station will have pigging facilities installed June 6-7, reducing San Juan capacity by an additional 325 MMcf/d. On June 9, El Paso will run a smart pig on Line 1600 from Waha to Gresham Station, cutting capacity from Waha west by 500 MMcf/d. For the rest of June and continuing into July, a program of pigging facility installations, pipeline cleaning and smart pig inspections will occur on four sections of Line 1212 between Blanco and Gallup, causing a variety of San Juan capacity reductions. See the bulletin board for details.

ANR has planned varying periods of maintenance on its Southeast Mainline starting June 4 and continuing through July 6. The date spans of the work and accompanying capacity reductions are: June 4-7, 25 MMcf/d; June 11-17, 136-218 MMcf/d; June 18-21, 65 MMcf/d; June 25-28, 25-195 MMcf/d; and June 29-July 6, 25-225 MMcf/d. The schedule will be updated as changes such as weather delays become better defined, ANR said.
