<br />set un <br /> <br />During the first week of pilot demonstration the equipment will be <br />setup on the edge at the disposal area. Since the irrigation pump <br />has a 150 foot (max) radius, one setup near the center of the <br />disposal area would appear to be ideal. Figure 1 shows the <br />anticipated set up. <br />The set up should be checked for coverage. Spray should not exceed <br />the boundaries of the CKD disposal area. <br />operation <br />During the full scale demonstration period sludge will be applied five <br />days per week (Monday through Friday). 15,000 gallons of sludge will <br />be applied each day. This represents six truck trips per day and is <br />the current disposal requirement. Hauling will begin at Sam and end <br />by 5pm each day. <br />During the full scale period, representatives of the State Health <br />Department will be present to watch the demonstration. This will be <br />done on a date agreed to in advance. These representatives will <br />include Phil Hegeman and Gary Soldano. <br />The full scale application should be made at rates that will not cause <br />ponding. Although the purpose of the sludge application is surface <br />stabilization of CKD, no one should enter the nit area due to the <br />danq_erous instability of CRD below the surface. <br />The period after the full scale demonstration will be used to answer <br />questions. Some of these questions will be the result of the full <br />scale demonstration. These questions will include: <br />1. Can a single spray gun cover the entire area adequately? <br />2. Does the gun have to be mobile or can it be fixed? <br />3. Is a gas driven pump better than electrical? <br />4. What is the maximum application rate before ponding occurs? <br />5. Are odors going to be a problem? <br />6. Can this operation be carried out without disrupting <br />Holnam's operation? <br />7. Does the spray gun perform adequately? ie., is there too <br />much dust disturbance? <br />Another question is what will the impact be at a heavy loading? e.g. <br />30,000 gallons per day (12 truck trips). At least one day at this <br />loading will be tried. This will challenge the system and provide <br />valuable information regarding heavy loading conditions which might <br />occur at peak plant loads or during an emergency. <br />Based on the results from the pilot operation, recommendations will be <br />made for full scale operation. The recommended method must be <br />acceptable to Holnam Inc., the State Health Department and the Fremont <br />Sanitation District. <br />2`. <br />
