This SAP <br />is being submitted in good faith by MSC as a cooperating party per your and the <br />San Joaquin County Environmental Health Department (EHD) earlier requests. <br />As you know, it is MSC's primary objective to close the above-noted <br />monitoring wells in place at the site. As such, on behalf of MSC, TRE proposes <br />to sample the subject monitoring wells for the following constituents of concern <br />(COC) that could potentially be attributed to MSC's industrial activities conducted <br />on site: <br />Polyaromatic Hydrocarbons (PAH): On behalf of its customers, MSC <br />stored and handled petroleum coke on site for exporting purposes <br />overseas. TRE, however, notes that the historical information revealed by <br />Dames and Moore's preliminary site assessment (PSA) report clearly <br />shows industrial activities and operations that involved storage of <br />materials which contain PAH that predated MSC's lease of this land parcel <br />from the Port of Stockton (Port) <br />Dissolved Copper: On behalf of its customer, MSC temporarily stored <br />copper concentrate on site. Hence, MSC proposes to conduct dissolved <br />copper analysis as a COC on ground water samples. TRE, however, <br />notes that other industrial activities predating MSC's operations and <br />activities, which might have contributed copper to the subsurface existed. <br />1
