S E C 0 R <br /> Ms. Vicky McCartney <br /> March 29, 2004 <br /> Page 6 <br /> Report. Following the completion of the CPT/HydroPunch@ assessment, <br /> SECOR will submit a report documenting the findings of the investigation. The <br /> report will include soil boring logs, seil--an"roundwater analytical results, chain- <br /> of-custody documentation, conclusions, and recommendations for installation of <br /> permanent deeper-zone monitoring wells, if warranted. <br /> SCHEDULE <br /> SECOR is prepared to initiate the coordination of fieldwork activities immediately following the <br /> approval of this addendum work plan. If petroleum hydrocarbon and/or fuel oxygenate impacts are <br /> observed in groundwater analytical results from the CPT/HydroPunch® assessment the need to <br /> install permanent deeper-zone monitoring wells will be evaluated by SECOR and the SJCEHD. A <br /> report documenting the findings of on-site vertical assessment activities will be submitted <br /> approximately six to eight weeks after the completion of fieldwork activities and upon receipt of <br /> laboratory analytical data. If deeper zone monitoring wells are necessary, the final report will include <br /> a work plan for deeper-zone monitoring well installation. <br /> If there are any questions regarding the contents of this work plan, please contact the undersigned at <br /> (916) 861-0400. <br /> Sincerely, <br /> SECOR International Incorporated <br /> ar At GAvw++�wucN <br /> M.
