Preliminary Closure and Postclosure Maintenance Plan 2-2 Department of Public Works/Solid Waste North County Recycling Center and Sanitary Landfill County of San Joaquin 2.0 Preliminary Closure Plan 2.1 General 2.1.1 Location and Background The NCRCSL is permitted as a single Class III, nonhazardous municipal solid waste landfill permitted under Solid Waste Facility Permit (SWFP) 39-AA-0022 and Waste Discharge Requirement (WDR) R5-2010-0016 (JTD Appendix A). The NCRCSL is located at 17720 East Harney Lane, Lodi, California, approximately nine miles east of Lodi, California (Figure 1). The facility property consists of 320 acres comprised of Assessor’s Parcel Numbers 065-120-02, 065-120-03, 065-120-08, and 065-120-09. The site is located in Section 21, T3N, R8E, MDB&M. The facility and surrounding topography are relatively flat, drained by the upper reaches of Patty Creek (Figure 2). The facility is located on land classified as urban industrial (waste facilities). The facility has been owned and operated by San Joaquin County since opening in 1991, primarily serving northern San Joaquin County. 2.1.2 Site Development The landfill will be developed by the extension of the liner into additional lined areas to a maximum elevation of 320 ft MSL (Figure 5) The landfill is developed as individually-lined areas, each constructed as needed to provide space for refuse disposal. Each of the existing lined areas has been constructed with liner systems that include an HDPE geomembrane and leachate collection and removal facilities. To date, refuse has been disposed in Areas 1 through 6, covering an area of approximately 88 acres (Figure 4). The landfill is currently planned to be developed in a total 11 lined areas. Development of the areas will be sequential in counterclockwise order (JTD Plate 6). Based on the progression of site filling and capital cost expenditures, the actual size of each area may be adjusted by the County (Figure 4). Total footprint after development will be 185 acres. The County intends to close the landfill in phases, potentially beginning with the western portions of the existing fill over lined areas 1 through 4. Additional areas will be closed as the landfill development continues. 2.1.3 Surrounding Land Use Surrounding land use has now been entirely converted to agricultural uses, with a combination of orchards, vineyards and field crops. (Figure 4). The land use south, east, and west sides presently consist of vineyards. Properties within a 1-mile radius include agricultural farmland on
