Ofos

Only a day after issuing them, Tennessee lifted two meter-specific Balancing Alert OFOs. The pipeline also said it continues investigation of a November rupture near Main Line Valve (MLV) 205-4 in Morgan County, OH, about four miles southeast of the city of Glouster (see Daily GPI, Nov. 21, 2011). Currently line 4 is isolated and Tennessee is maintaining a reduced pressure from Station 200 in Greenup, KY, to Station 219 in Mercer, PA. The Rockies Express (REX) interconnect flows into Line 4 between MLVs 208 and 209. To further evaluate the section between the valves, Tennessee was required to reduce the pressure there. Thus it was not accepting any nomination increases at the REX meter Tuesday and effective Wednesday until further notice will not accept any nominations at all from the REX meter.

Pacific Gas and Electric, which has had simultaneous Stage 1 low-inventory/high-inventory OFOs in effect consistently on its California Gas Transmission system since it began them July 8 due to lower pressures from pipe remediation work (see Daily GPI, July 8), said it will have an OFO-free gas day Thursday.
