In an update on its 500 Line force majeure declared last week in connection with Atchafalaya River flooding, Tennessee said it had determined that the pipe section between Main Line Valves (MLV) 516 and 518 did not need to be isolated along with the segment between MLVs 518 and 521 after all. Thus three meters that it had subsequently added to an original list of five slated for shut-in were allowed to keep flowing. Tennessee also said it had returned to service Monday the 800 Line after completing an outage from MLV 827-1 to MLV 830-1 that had required suspension of physical flow at two meters; however, Station 834 will remain offline through Wednesday for various repairs and maintenance.
Saying a mechanical failure at the Clay Basin storage facility that caused a temporary reduction of total injection capacity to 325,000 Dth/d (see Daily GPI, May 17) had been repaired, Questar restored the capacity to its normal 375,000 Dth/d Tuesday.
CIG said it recently identified the need for a repair at its Totem Storage Field that will impact firm service. It expected to finish Totem reservoir maintenance, which was limiting injections and withdrawals at Kiowa Creek Meter Station to zero, on Tuesday. But to further evaluate the additional repair work it has identified, beginning with Timely Cycle nominations for the May 24 gas day until further notice CIG will cut injections and withdrawals at Totem to zero.
Pacific Gas and Electric said pipeline upgrade work that will reduce off-system capacity at Kern River Station to zero is currently rescheduled for May 25-28; it previously was set for April 27-29.
