Based on the comparisons m Table 1,the shredded green material is recommended as suitable for use in a pilot program at both Austin Road and French Camp Landfill. Section 1.3 Expected Performance Based on the following discussions related to each of the above criteria, The City of Stockton believes ground green material is suitable for use as cover material on the daily refuse working face area. Fires - Water trucks used in the disposal area for dust control are available to provide for the immediate extinguishing of any incoming load of refuse that is on fire,thereby prohibiting any visible burning material from disposal into the daily refuse cell. The dozer will be available to smother any fire at the active fill face with native soil. Because of the anaerobic conditions found in a compacted refuse cell, fires rarely occur in a completed cell. Infiltration of surface water runoff-Existing operations at both landfills combine design conditions and construction of the daily refuse cell to maintain a positive grade to divert water away from areas of active filling, thus avoiding contact between the proposed ground green material and surface water runoff. The green material alternative cover should control water movement to minimize moisture infiltration, leachate production, and erosion. During the heavy rain periods, the Covertech C- 440, would also be used as an alternative cover at Austin Road Landfill, in the event shredded green materials aren't accessible at the site. However,prior verbal approval from LEA staff is required before use of the Covertech C-440. Vectors -Vectors usually associated with landfill operations include rodents and flies. Previous studies indicate that while rats may on occasion be found in loads brought to the landfill, they do not survive the compacting process of the local collection truck or the compacting process at the landfill and are therefore not considered a problem with respect to emergence from daily cover material. Ensure sightly appearance-This will be closely monitored for compliance by the Landfill Operator and LEA inspectors. The refuse is trimmed to a flat surface prior to application of the alternative daily cover. Odor- Previous studies indicate that the yard and green material cover actually masked much of the refuse odors during its exposure period. Off-site odors as a result of using this material are not foreseen to be a problem. Section 1.4 Evaluation of Past Performance This section includes a discussion of past problems which may have been related to performance of the cover soils which have been used at the site and how the alternative cover would help alleviate the problems. At both landfills, due to the clay nature of the soil, it is difficult to move soil during the wet season. The City's Landfill Operator, Gambi Enterprises, Inc. (Gambi), will submit a 6
