Mike I wanted to give a short update on the latest events related to the PCB
issue with PG&E. Transwestern met with PG&E this last Wednesday with an agenda that included some sharing of sampling results collected downstream of their first C/S (Topock) and on out west toward their main distribution areas. With respect to the most recent sampling data, Low PCB concentrations (N.D. to 38 ppm) have been detected in drips and interconnects between Topock and Hinckley C/S. The good news is that PCB's have not been detected downstream of Hinckley which is approx. 160 miles from the Topock C/S. PG&E has also initiated construction and installation of some drips and small separators at locations where their gas feeds into other lines or directly into customers. the proposed installation date for the large mainline filter separators is still on target for 6/1/00. Now for the bad news. At the conclusion of the meeting, PG&E has stated that they want their Topock C/S decontaminated. This includes all piping and equipment. I stated to them the impractabibility and zero success rate of removing all the PCB's from their system and that there would be no quarantees that the deconning would be successful. The contract PCB deconning companies only have permits which would guarantee cleanup to 10 ug. They were told that it would be impossible to clean everything and that in all probability the PCB concentrations would be showing up as the gas continues to move through the system. Additionally, the better remediation approach would be to continue to remove PCB containing liquids at strategic locations. Even with this, they were pretty insistent that their management wanted the facility cleaned. Preliminary $$ estimates range to approx. 3-5 million. I think that this is only the "tip of the iceberg". If they are successful with this action, the pipeline system will be next. Their pipeline is not piggable and to make it such would require replacement of pipe, valves etc. Ill keep you informed on this,,,,,,,
