Details were still somewhat sparse Saturday, but Northwest Pipeline was able to confirm that there had been a line failure on its pipeline near Stevenson, WA Friday night about 8:20 (PST). Personnel were immediately dispatched to the site to secure the area. As of press time Saturday, no injuries were reported and the cause of the incident was under investigation.

Although sources weren’t in the office at the time, they likely were scrambling to re-source gas that had been flowing through Sumas. The Stanfield, OR interconnect with PG&E Gas Transmission-Northwest was downstream of the rupture and less affected, but replacement of lost supplies may have lifted Rockies prices in intra-day deals over the weekend. Northwest service to some customers of LDC Cascade Natural Gas was interrupted briefly early this year by a rupture near Pendleton, OR (see Daily GPI, Jan. 5).
