Y approved, this will be identified as Lodi Task 19 — Strategic Consulting Services. BACKGROUND Five groundwater contaminant plumes have been identified within the City of Lodi. One of these plumes, the Central Plume, is currently scheduled for source area remediation beginning in late 2009. A second plume, referred to as the Busy Bee plume, is being remediated by the responsible party, with minimal interaction with the City. The three remaining plumes (the Northern, Southern, and South Central plumes) have not yet progressed to a point where specific remedial actions have been identified or scheduled, although the revised Corrective Action Order (CAO) currently being reviewed by Regional Water Quality Control Board does discuss these plumes in general terms. I t is anticipated that the revised CAO will set a general schedule for addressing the three remaining plumes and the off-site plume associated with the Central Plume source area, SCOPE OF WORK The proposed scope of work includes two tasks that are listed below: SUB -TASK 1: Strategic Consulting — T&R will provide the City with Principal -level support in planning approaches to dealing with the remaining groundwater contamination associated with the five contaminant plumes. This work may include meeting with City staff and legal counsel, reviewing new technical documents prepared by others as they become available, representing the City during meetings and negotiations with regulators and other responsible parties, preparing reports for the City, and briefing City officials as needed. We expect that most of the work will be performed by Mr. Philip Smith, with technical support from others as needed. • SUB -TASK 2: Complete the EE/CA and revised CAO — T&R will work with the City to address any additional comments received from the Regional Water Quality Control Board, legal counsel, or others to finalize the Engineering Evaluation/Cost Assessment (EE/CA) and revised Corrective Action Order (CAO). We understand that the EE/CA has been reviewed by the Regional Water Quality Control Board but not formally accepted, and that the revised CAO is in Regional Water Quality Control Board review. It is also our understanding that the Action Memo describing the source area remediation plan will be required, and is part of this deliverable.
