System integrity work on the 36-inch Grande Prairie Mainline is on schedule (see Daily GPI, Feb. 26) and all affected services are scheduled to be restored at the start of Wednesday’s gas day, NOVA reported Tuesday.

Marketing and trading is central to a deregulated natural gas market, and it is gradually and very quietly being restored as producers and utilities hire traders to build their marketing departments. Traders who once worked for major marketers who were part of the “midstream meltdown are being dispersed into smaller shops,” said Edward M. Kelly, head of North American gas and power consulting for Wood Mackenzie.

NOVA restored its imbalance tolerance range to the normal +4/-4 Tuesday, a day after shifting it to 0/-4 to discourage rising linepack.

Columbia Gas Transmission, a unit of NiSource Inc., said service was completely restored last week to the handful of residential customers in West Virginia who lost service following the rupture of a 30-inch diameter looping line carrying about 600 MMcf/d of gas through a rural area near Charleston. The pipeline rupture caused a fire last Monday at 11 p.m., but no injuries were reported. Gas transportation service was diverted onto a parallel pipeline.
