compost will bring the water content of the compost to proper levels and will eliminate the potential for pathogen regrowth in the active compost. There are th ree agr icu lturefour production water wells and one domest ic we ll at the site. One well, located near the main entrance facility was drilled to a depth of approximately 135 feet and groundwater occurs at a depth of approximately 70 feet. The well was likely installed before the opening of the landfill, having been previously used for agricultural purposes. It is pumped at a rate of approximately 1,500 gallons per minute (gpm) at a maximum frequency of approximately 27 times in a typical working day. Another well is located south of the South Fork of South Littlejohn's Creek in the southeast corner of the RRF and Compost Facility area, and has a capacity of 500 gpm. The third well is located along the northern boundary of the former Austin Road Landfill. This well was installed in 1972 and has a production of approximately 60 gpm. The fact that groundwater flow near the existing Forward Landfill is not modified by pumping from this well suggests that it is screened in a confined unit below the uppermost groundwater units that are monitored at the site. One domest ic well ,The fourth production well is located along the eastern boundary of the site, just south of the entrance to the Compost Facility/RRF. The locations of the wells located in the Compost Facility/RRF area is shown on Figure 1. Since water will only be added to the compost to maintain adequate internal moisture, significant leachate generation is not antiCipated. There is no on-site wash water generated. Therefore, no wastewater is generated; however, should some be generated it will be collected and discharged to the Class II surface impoundment utilized as a leachate pond. 3.8 MATERIAL PROCESSING, HANDLING, AND STORAGE PRACTICES 3.8.1 Processing 3.8.1.1 Feedstock The Compost Facility will operate between the hours of 6:00 a.m. to 6:00 p.m. Monday through Saturday and is closed on Sundays and on Christmas Day and New Years Day. During the week, the RRF accepts materials up until 4:00 p.m. in order to process and/or cleanup prior to 6:00 p.m. Odors are controlled by processing and removing the material as soon as possible after being brought into the RRF. Odors are not anticipated from the materials since it will be stored for no more than 48 hours. 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 is utilized to extract nails and other ferrous contaminants from the green waste material after it has been shredded. Since incoming biosolids are not anticipated t o have heavy metal concentrat ions above regu latory limits, ot her preprocessing pro cedu res 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.
