I. INTRODUCTION A. BACKGROUND The City of Stockton Department of Public Works (DPW)is proposing to expand the City's Austin Road Landfill both horizontally and vertically. The existing landfill,located seven miles southeast of the City of Stockton, consists of 187 acres. The existing 187 acres are currently permitted as a landfill: 169 acres are for fill,the remaining 18 acres are for easement purposes. The North Branch of the South Fork of Little Johns Creek runs through the existing landfill. Of the 169 acres permitted for fill,45 acres are to the south of the creek and the remaining 124 acres are to the north of the creek. Currently,the 45 acres are used as a borrow area(soil is taken to the active fill area to be used as daily cover). This area will eventually be filled. The current fill area of 124 acres is bounded by Austin Road to the east,the landfill access road to the north, Newcastle Road to the west, and Little Johns Creek to the south. The DPW proposes to expand horizontally north and southeast of the landfill on 218.5 acres of property it owns and property it proposes to acquire. The expansion would result in a total of 405.5 acres for the Austin Road Landfill. Of the 218.5 acres being added to the landfill, approximately 85.6 acres to the southeast would be for fill and the remainder would be for ancillary facilities,right-of-way, and flood control easement. The proposed expansion would be constructed to meet new Federal Resource Conservation and Recovery Act(RCRA), Subtitle D regulations for solid waste landfill design. The DPW also proposes to increase the current maximum elevation of 90 feet mean sea level (MSL)to 150 feet MSL. The new elevation would be approximately 120 feet above ground level (AGL). The vertical expansion would occur on top of the existing landfill,only after it has been properly closed and after the horizontal expansion to the south has been completed. This is proposed to allow the existing landfill to stabilize over approximately 30 years. The DPW plans to continue to accept its current waste stream: that is Municipal Solid Waste (MSW). The landfill currently does not accept sewage sludge,asbestos,whole tires,abandoned vehicles,large dead animals,liquid wastes,hazardous wastes,inert solids,or white goods. This would not change with the project. I.1
