A � � /4 Exhibit A City of Stockton French Camp Landfill Groundwater Investigation Scope of Services Camp Dresser&McKee Inc. (CDM)submitted a proposal to the City of Stockton(City) dated November 6, 1995,to conduct a groundwater investigation at the French Camp Landfill. This was in response to the City's request for proposal(RFP) approved by the Stockton City Council on September 25, 1995 (Resolution No. 95-0462). CDM's proposal provided a detailed description of the tasks required to conduct the investigation. The tasks identified were based upon the groundwater investigation work plan prepared by CDM dated March 21, 1995,and approved by the Central Valley Regional Water Quality Control Board (CVRWQCB). The City's RFP process followed the procedures described in Stockton City Council Policy 300-1. A selection committee was formed,proposals were screened,and consultant interviews were conducted. Before making a selection decision,City staff met with CVRWQCB staff for advice regarding the various technical approaches proposed by the consultants interviewed for the work. Following this meeting,the French Camp Landfill Consultant Selection Committee decided that the City should enter into contract negotiations with CDM. The Committee ranked CDM as the most qualified consultant for the work. As a result of the discussions with CVRWQCB staff,City staff concluded that the original RFP scope of work for the project would be modified to reflect input from the regulator. City staff reached this conclusion because CVRWQCB staff stated that regardless of what results the original groundwater investigation scope of work produced,some form of corrective action would still be necessary. Therefore,before going any further with CDM contract negotiations,the City decided to meet again with CVRWQCB staff and to agree on the number and locations of proposed groundwater monitoring wells. In order to prepare for this meeting,the City required CDM's assistance in developing a revised approach to the groundwater investigation. This work was conducted in accordance with the Scope of Services entitled "French Camp Landfill Groundwater Investigation Phase I" dated March 28, 1996. Staff from the City and CDM met with the CVRWQCB on May 23, 1996 to discuss the number and locations of groundwater monitoring wells. A revised approach was agreed upon to expand the detection monitoring program. This Scope of Services(Scope) describes the tasks necessary to install the proposed monitoring wells,collect environmental samples,and to evaluate the data collected. The remainder of this Scope consists of two sections. The first section presents,on a task- by-task basis, the activities necessary to implement the groundwater investigation. The Scope will conclude with the project schedule and the costs associated with the implementation of the activities identified. CDM Camp Dresser&McKee 1 w9s%zsoo=s i
