Spreckels Work Plan Cover Letter <br />Introduction <br />This Permit Package includes the formal Closure Work Plan submitted to and approved by the <br />Regional Water Quality Control Board (Board). The formal Closure Work Plan includes analyses <br />of data not pertinent to the explorations included in this permit package. We have prepared this <br />cover letter to briefly explain the background history and proposed field explorations relevant to <br />this Permit Package to expedite review. Please refer to the formal Closure Work Plan for <br />additional details, and please contact Anthony Wohletz (Phone: 530 321-1280, Email: <br />awohletz@kleinfeldercom) with any questions. <br />Background History <br />Kleinfelder conducted initial Phase I investigations and Phase II sampling for the Spreckels site <br />(Site) starting in 1997, when the general area was being developed. This Site was part of the <br />former Spreckels sugar-processing factory. AKF acquired the land associated with the larger <br />sugar-processing factory for development, and Kleinfelder conducted factory-wide Phase I <br />investigations and Phase II sampling and analyses. <br />San Joaquin County provided regulatory oversight, and Kleinfelder worked closely with their <br />regulators to direct Phase II investigations, analyses, and remedial events in order to gain closure. <br />The County, however, lost the resources to complete regulatory oversight, and the Spills, Leaks, <br />Investigation, and Clean-up (SLIC) case remained open. <br />A recent Phase I related to the pending sale of this Site revealed the open SLIC case, which the <br />buyer has requested be closed prior to purchase. Kleinfelder is therefore aiding the current owner <br />(AKF Development Holdings LLC [AKF]) in reviewing past investigations, obtaining regulatory <br />oversight, and ultimately obtaining closure and has applied for a Memorandum of Agreement <br />(MOA) and Request for Agency Oversight with the Regional Water Quality Control Board (SLIC) <br />Unit. <br />Work Plan <br />Kleinfelder has coordinated with the Board to analyze past Phase ll data and propose new <br />investigations to obtain additional data. The formal work plan breaks the Site into Operable Units <br />and analyses existing Phase II data for each. Many of these analyses find that additional <br />exploration is not necessary, and therefore are unrelated to this Permit Package. To facilitate <br />work plan review, field exploration related to this Permit Package is summarized below: <br />Two push probes will be advanced in the vicinity of past explorations related to a septic <br />system that was removed sometime around 1997. Three soil samples and one grab <br />groundwater sample will be collected from each, for a total of six soil samples and two <br />groundwater samples. Samples will be analyzed for CAM 17 Metals and general <br />chemistry (including carbonates, bicarbonates, nitrates, potassium, sodium, <br />ammonium-nitrogen, organic-nitrogen, chloride, sulfate, and phosphate). Further <br />details are in the Operable Unit 1 Section of the formal Closure Wok Plan. <br />Total push probes: 2 <br />Total vapor wells: 0 <br />Total holes: 2
