Work Plan For Additional Groundwater Delineation and Ozone Microsparge System Installation,Tosca(Former BP)Station No.]1195 <br /> September 19,2002 <br /> PROJECT STAFF <br /> Mr. Douglas J. Lee, a Registered Geologist in the State of California (R.G. No. 6882) will <br /> provide technical oversight and review of the work. Mr. David Vossler, project manager, will <br /> supervise implementation of field and office operations. GR employs a staff of geologists, <br /> engineers, and technicians who will assist with the project. <br /> SCHEDULE <br /> Implementation of the proposed scope of work will commence upon receipt of regulatory approval. <br /> GR proposes the following schedule for the installation of additional groundwater monitoring <br /> wells and the ozone microsparge system: <br /> 1. An encroachment permit must be obtained from the City of Lathrop prior to installation of <br /> the offsite monitoring wells. <br /> 2. The proposed monitoring wells and sparge points are anticipated to be installed by December <br /> 31, 2002,pending approval by the City of Lathrop and the EHD. <br /> 3. The ozone system is anticipated to be operational within one month of the installation of the <br /> sparge points, depending on contractor availability. <br /> 4. A monitoring well installation and ozone system installation and startup report is expected to <br /> be submitted by February 15, 2003. <br /> Adherence to this proposed schedule is dependent upon acquisition of offsite access and <br /> encroachment permits. Unforeseen delays in the issuance of these items may necessitate that the <br /> schedule be modified. GR will inform the EHD of any changes to the proposed schedule. <br /> REFERENCES <br /> Gettler-Ryan Inc., 2002, Interim Corrective Action Plan, Tosco (Former BP) Service Station No. <br /> 11195, 16500 South I-5, Lathrop CA.,Dated August 28, 2002. <br /> ..., 2002, Monitoring Well Installation Report, Tosco (Former BP) Service Station No. 11195, <br /> 16500 South I-5, Lathrop CA., Dated July 24, 2002. <br /> 140193.14 6 <br />
