The specific mixtures of feedstocks to achieve these parameters are impossible to calculate <br /> given the large number of potential feedstocks described in this permit application. The <br /> actual feedstocks available and the relative proportions will dictate the development of <br /> suitable mixtures. <br /> Temperature of the active compost will be monitored to comply with the State and Federal <br /> requirements to meet pathogen reduction criteria and also as required for sufficient process <br /> control. Moisture content of the active compost will also be monitored as necessary to <br /> provide for proper process control. Monitoring results will be documented and records will <br /> be maintained at the facility. <br /> Water Supply. There are three water wells at the site. A 2,000-gpm well at the landfill <br /> entrance facility, a 1,000-gpm well for fire and dust control at the rear of the RRF, and a 20- <br /> gpm for domestic use located in the front of the facility. There will be an approximately <br /> 8,000-gallon water tank in the South Area near the Compost Facility operations area. <br /> In addition, water is available from the storm water runoff retention pond. These water <br /> supplies are available for initial mixing of the compost to bring the water content up to <br /> desired levels, wetting of the compost, dust control, and other applications through use of <br /> on-site water trucks. <br /> Preprocessing. Preprocessing and initial handling of feedstocks is also common to <br /> the alternatives. Materials with large particle sizes such as wood waste, green <br /> material and agricultural wastes may require grinding before composting. These <br /> materials will be handled in the existing RRF and ground using the existing grinder. <br /> Additional grinding capacity will be added, as necessary, to handle the required volume <br /> of material. Green material high in grass will be mixed as soon as possible with ground <br /> wood waste and/or recycled compost and/or other relatively dry and low C:N feedstock <br /> to minimize odor production. <br /> MSW preprocessing depends on the final use of the composted product. Little or no <br /> preprocessing is required if the compost is to be directly landfilled or used for landfill <br /> cover. Removal of large objects is necessary to prevent damage to Windrow turning <br /> equipment and grinding will aid decomposition during composting. Low technology <br /> windrow composting of MSW has been successfully implemented in the U.S. If a higher <br /> quality product is desired, extensive pre-processing is necessary. This could consist of <br /> manual picking of metal, plastics and glass from the incoming material or receipt of <br /> source-separated waste. <br /> Grinding and trommel screening of the material prior to composting has significantly <br /> improved the quality of the final compost product. More mechanized processing has <br /> included magnetic and eddy current separation for improved removal of iron and <br /> aluminum components of the waste stream. The decision on the amount of <br /> preprocessing will be determined by economics and the final use of the compost product. <br /> Semi-solid materials such as grit, biosolids, food processing residue, food waste, garbage, <br /> and liquid wastes such as grease, holding tank pumpings, and septic tank pumpings will <br /> be placed on other materials such as ground green material or wood waste or recycled <br /> compost and mixed as soon as possible to minimize the potential for leachate formation <br /> and odors. The amount of these materials accepted will be limited by the availability of <br /> other feedstocks. <br /> Forward Composting Facility RCSI <br /> 7/20/09;Page 11 SWT Engineering <br />
