I. Introduction B. w iD F The City of Stockton has operated a landfill at this location since 1960. The landfill is operated for the DPW by a private contractor,Gambi Enterprises,Inc. The DPW provides disposal services for the residents and commercial sector within the incorporated of Stockton. The landfill accepts MSW from contract and permitted haulers from the City of Stockton. No private self-hauler is allowed to bring waste directly to the landfill. This section examines the relationship of the proposed expansion,including its capacity,to the rate of waste generation in the service EXPANSION CAPACTrY The site capacity of a landfill is determined by calculating the volume available between the elevation of the top of the bottom liner system and the bottom of the final cover. The refuse capacity is then calculated by estimating the volume available for refuse when considerations are made for the expected compaction ratio and the use of daily and intermediate cover. The service life of the landfill is determined by comparing the.calculated volume available for refuse with the projected waste stream. According to these calculations,the existing landfill to the north of the North Branch of the South Fork of Little Johns Creek will close in 1997 (R.W.Beck and Associates, 1993). This project would extend the life of the permitted landfill to 2045,an additional 48 years. The 45 acres to the south of the North Branch of the South Fork of Little Johns Creek is included in the existing solid waste facilities permit as a borrow area. It cannot be used for landfilling under the current permit without a CEQA review and permit revision. Appendix A includes a table showing projected waste generation,diversion,transformation and disposal from 1992 through 2045. This table was prepared by R.W.Beck and Associates to determine the service life of the proposed landfill. The proposed Austin Road Landfill expansion would have a total air space(from the bottom of the liner to the top of the final cover) of 18 million cubic yards(CY),of which approximately 14 million CY would be taken up by refuse and 4 million CY would be required for cover material(daily,intermediate,.and final cover). Using a conservative estimate for the in-place waste-density of 1,200 pounds per CY (lb/CY),the proposed landfill expansion could accept a total of 9 million tons of refuse(R.W. Beck and Associates, 1992). Without the project expansion,the City of Stockton will be faced with finding an alternative disposal site by 1997. I.3
