3.8.1.2 Processed Material Incoming material undergoes preprocessing to remove any visible contaminants. Loads are visually inspected at the RRF and will be manually sorted in the processing area. A magnetic separator will be providedis utilized to extract nails and other ferrous contaminants from the green waste material after it has been shredded. Since incoming biosolids are not anticipated to have heavy metal concentrations above regulatory limits, other preprocessing procedures will not be necessary. The compost process time is projected to be between approximately 4 to 12 weeks, depending on the compost product quality. The curing process will take approximately 1 to 6 months. 3.8.2 Pile Geometry 3.8.2.1 Feedstock Sorting bins and wood waste stockpiles are located on the permitted property surrounding the RRF building. The stockpile area of the RRF expands and contracts depending upon the amount of materials sorted and the re-sale market. 3.8.2.2 Processed Material The waste materials arewill be formed into compost piles which arefbe6s approximate ly ±815 feet wide by 12 feet tall at center high , approximately 18 feet w+ee , and of varying length ~ (up to 300 fee t long). The active compost will be mixed as required for proper control depending on temperature and moisture profiles and season (turning will be kept to a minimum during the rainy season). The frequency of the windrow turning and water addition will be determined by monitoring the pile temperature and moisture content. Temperatures within the active compost will be monitored daily using hand-held temperature probes. As the materials in the active compost age, the volume of the compost decreases. Windrows will be combined with neighboring Windrows to maintain the desired pile dimensions. 4.0 CONT INGENCY PLANS 4.1 FIRE PREVENTION Forward, Inc. has a number of site and personal safety procedures in place as detailed in the Contingency Plan. The following equipment and systems have been installed at the site to prevent and control accidental ignition of combustible materials and can be employed at the Compost Facility: • Fire extinguishers-inspected routinely and recharged, as necessary. • Annual fire inspections by the Manteca-Lathrop Fire Department. • A dirt supply is kept near the working face to smother a potential fire. • Two water trucks are available. • Emergency 4 1/2 inch fire hose hook up s are located in the southeast corner of the landfill, north of the South Fork of South Littlejohn's Creek and a 2 1/2 inch f i re hose hool~ up in the entrance facilitiesnortheast corner of the site for the fire department.
