El Paso changed the pigging schedule for Line 1102 from Plains to Dumas; see the bulletin board for operational details and capacity effects. It also postponed to an unspecified later date, pending delivery of critical parts, a total shutdown of the Window Rock Station that had been planned for Thursday (April 24). However, Window Rock’s A Plant only was down for Department of Transportation inspections and gas cooling equipment tie-ins Thursday, with the 7A turbine remaining down through Friday. This work, in combination with ongoing maintenance at Flagstaff Station and on the Window Rock 2B turbocharger, will reduce capacity of the North Mainline by 160 MMcf/d Friday, by 110 MMcf/d Saturday, and by 26 MMcf/d Sunday through Tuesday.

Citing increasing soil and ambient temperatures, NOVA said Thursday it requires a decrease in target linepack and thus is requesting unconditional tenders for the firm sale of 390,000 gigajoules. Tenders may be submitted for all or some of the gas. The sale, to be accomplished through on-system inventory transfer, must take place over a period of up to eight days starting on or about May 12, NOVA said. Call Jeff Stoffregen at (403) 920-6337 or George Phillips at -6825 for more information.
