DESCRIPTION OF THE PROJECT The project site proposed for replacement of the existing Harney Lane Landfill is a 320 -acre parcel which is the west one-half of Section 21, T.3N., R.8E., M.D.B.&M., shown on the U.S.G.S. "Linden" 7.5 Minute Topographic Map. The site is located on the south side of Harney Lane approximately one mile east of the existing landfill. The proposed site would serve the northern areas of the County (north of Eight Mile Road) including Lodi except for the Thornton area, which uses the Sacramento County Landfill. To handle the increased traffic, Harney Lane from Jack Tone Road to Clements Road would be scheduled for improvement prior to commencement of site operations. The proposed site is in conformance with the San Joaquin County Solid Waste Management Plan which dicusses development of a replacement site or expansion of the existing Harney Lane Landfill. The existing Harney Lane Landfill is anticipated to reach capacity in 1984. Accord— ing to the San Joaquin County Solid Waste Management Plan, approximately 1,650 tons per week (seven-day basis) of residential and commercial solid waste are disposed at the existing Harney Lane site. An additional 5,800 gallons per week of septic tank pumpings are mixed with solid waste at the site. The proposed site as the intended Class II -2 replacement for Harney Lane Landfill would then receive these Groups II wastes. No hazardous wastes would be accepted at the site. Metals recovery is expected to continue at the proposed site when fill operations are completed at the existing facility. Expanded resource recovery measures may be implemented upon further study. At present, the anticipated method of operation for the replacement site would be to operate as a cut and fill method (see Figure 6), similar to that which is in use at the existing Harney Lane site. Existing equipment at the site, consisting of two crawler tractor dozers, two self -elevating scrapers, one front loader, one drag line, and a water truck would assist in the proposed site's development. No night time operation of landfill equipment is anticipated. The proposed landfill would be developed in approximately 20 -acre plots beginning in the extreme southerly end of the property (see Figure 7). A buffer zone along the property line would be maintained so that remedial actions can be taken, if necessary, to control litter and gas and leachate migration. A gravelled access road extending from the site's entry off Harney Lane, south through the center to the site's active fill area would be maintained for all- weather use. Realignment of South Paddy Creek is intended to be made during the initial stages of development. This would provide security and controlled access to the site. The first 20 -acre plot would be under active filling, while excavated soil would be stored on an additional 20 acres. The final 20 -acre plot would be for miscellaneous operations, including equipment storage and maintenance. Each trench will be sloped to one or more points in order to collect leachate, if generated. On-site soil or artificial liners will be used at the base of the fill area to prevent any subsequent infiltration of leachate to groundwater. An observation pipe extending from above grade to the dis- posal trench bottom will provide for continued monitoring and access to leachate
