k%j KLEINFELDER The Spreckels factory stopped sugar production in August 1995. Since that time, almost all of the water in the wastewater ponds has been from stormwater runoff. On February 27, 1996, John M. Minney of Madera Ranchos, California composed a closure plan for the time ponds on site. The closure of the remaining ponds on site were not addressed. The plan was very general and did not discuss the specifics for the closure. On August 19, 1996, the CVRWQCB responded to the April 24, 1996 closure plans by John Minney. In the review letter, the CVRWQCB stated that the closure plan by Mr. Minney was incomplete, and requested a detailed Report of Waste Discharge and a detailed Closure Plan for their review. On September 23 1997, the CVRWQCB issued "Revised Waste Discharge Requirements for Spreckels Development Company, Former Spreckels Manteca Sugar Plant, Lime Pond Closure, San Joaquin County". The Revised Waste Discharge Requirements Order No. 97-204 (hereinafter "WDRs") detailed the requirements the CVRWQCB had on the property owner. The WDRs required additional monitoring at the site. Included in the monitoring well network was Monitoring Well MW-3. However, the WDRs allowed for the monitoring wells to be abandoned and moved to a"like hydrogeologic location", if development required. Currently, the lot that contains MW-3 is in escrow for a proposed distribution center. The buyer or lessor is requiring that the well be moved off site. 4.0 SCOPE OF WORK Kleinfelder's scope of work includes the abandonment of monitoring well MW-3. The one monitoring well (MW-3r) will be installed for the replacement for the existing monitoring well MW-3. MW-3r will be installed in accordance with the same methodology that was approved for the relocation of MW-6 (in the residential area of the former Spreckels site) to MW-6r on the southeast comer of Yosemite and Powers Avenues, except as outlined in the letter by Mr. Ross Atkinson of the CVRWQCB. 4.1 Drilling Permit and Workplan Submittal Kleinfelder proposes to install a total of one (1) monitoring well in a boring advanced by a truck mounted drill rig at the location detailed on Plate 2. The San Joaquin County Public Health Services Department Environmental Health Division (PHS/EHD) requires a workplan and permit application for the installation of monitoring well. Additionally, the CVRWQCB required that a workplan (this document) be submitted. The proposed monitoring well installation in addition to the abandonment of MW-3 will each require permits, and this workplan should be submitted by the client to both agencies for review. Kleinfelder will also prepare a health and safety plan for use in the field. 20-YP9-329/2000P044/2000W005 Page 6 of 12 Copyright 2000, Kleinfelder,Inc. February 8,2000
