Page 2 of 2 <br /> sites. After review of the maps,an agreement was reached that the percentage of responsibility of the plume would be <br /> estimated using area and volume calculations with mutually agreed upon assumptions and data gaps. The consultants for <br /> each RP will continue to work together to arrive at a percent plume responsibility for the Commingled Plume Verification <br /> Report. Based on the review of the isoconcentration maps,the RPs agreed that the percentage of responsibility would be <br /> similar to an even split by the 5 or 6 RPs involved. Therefore the cost sharing agreement will be structure to split cost <br /> evenly at 16.6%(If the Transmission Store is involved)or 20%if there are only 5 participants. Since Mr.Rodgers of <br /> the Transmission Store was unable to attend,a decision on their participation was not yet obtained. The 5 participating RPs <br /> discussed the benefits and concessions to be made to Mr.Rodgers and the Transmission Store. Charles Metzinger of Shaw, <br /> stated that this information would be provided to Mr.Rodgers so that he could make an informed decision. <br /> The other significant decision that was reached in the meeting was the selection that Mr.Sergio Morescalchi of BP who <br /> volunteered to serve as the CPA Lead for RPs. Agency correspondence and communications will be the responsibility of Mr. <br /> Morescalchi once the CPA Plume Application is submitted. <br /> Mr.Barton,during my conversation with you last week,you had indicated that we should contact Mr.Rodgers to establish <br /> a deadline on his decision to participate in the CPA. I contacted Mr.Rodgers later in the week and unfortunately he has been <br /> experiencing some health issues. He did not have a chance to meet with his consultants regarding the January 23rd meeting. <br /> He thought that this week he should be more fully recovered and anticipated talking to Shaw. I will contact him again near <br /> the end of this week to see if he has made his decision. <br /> You had also requested a schedule for submittal of the application. A Gantt chart with this schedule is attached. <br /> If you have any questions or comments regarding this status report or the attached schedule,please do not hesitate to call. <br /> We look forward to working with San Joaquin County and the Central Valley Regional Water Quality Control Board to <br /> solve this environmental problem. <br /> Sincerely, <br /> John R.
