USTCFP Pre-Approval Request Page 3 Bank of Stockton-Cutter Project 102.2 November 20, 1996 The eight proposed soil borings will be logged and sample by a professional geologist under the supervision of a Registered Geologist, and selected samples will be tested for the presence of gasoline and diesel range petroleum hydrocarbons and BTEX compounds. The purpose of this work is to help determine the lateral and vertical extent of hydrocarbons in the vadose zone, and at the capillary fringe. A report will be prepared and submitted to regulatory agencies which describes the work, its results, and discusses the implications. In addition, the existing idle domestic water well will be properly plugged and abandoned The results of the proposed work will be used as the basis for designing and planning additional work to complete the site characterization and to assist in determining what, if any, remedial activities may be appropriate. It is anticipated the follow-up activities will include the installation of at least 3 groundwater monitoring wells, and may also include a passive soil gas survey to assist in the determination of the lateral extent of the plume. III. Anticipated Schedule of Work The following is a summary of the anticipated schedule for the work described above. EVENT DATE Receive USTCFP Pre-approval for Expenditure 12/10/96 Perform Field Work 12/20/96 Submit Report of Work 1/15/97 Submit Work Plan for GWM Wells and/Other Work 2/15/97 IV Request for Pre Approval of Expenditures for Preliminary Site Characterization Phase One Environmental Inc. has prepared a Work Plan (copy attached) describing the proposed work and its methods and protocols, and has submitted copies to the LOP and the RWQCB. On October 17, 1996, the LOP approved the Work Plan as submitted. On November 18, 1996, and addendum to the Work Plan was submitted (copy attached) which modifies the scope of work in the original plan by adding the abandonment of the existing idle domestic water well. We have solicited bids from three companies to perform the drilling work, and have price lists from three state certified laboratories for analytical testing. We also have asked the low bidder to provide a supplemental bid to perform the domestic water well abandonment. We have prepared a budget sheet (copy attached) which summarizes the anticipated tasks associated with the proposed work described in the Work Plan, and which reflects the bid requests obtained.
