Forward Compost Facility – OIMP 9 SWT Engineering <br />z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2013-14\rcsi 2014\appendices\app e-oimp\oimp <br />text.doc; 7/18/2014 <br />and in the equipment maintenance building at the landfill. Landfill personnel are <br />trained to perform initial fire suppression activities using appropriate site equipment, <br />stockpiled soil cover, and when necessary, a water truck. <br />The on-site water wells and a water storage tank provide water for fire suppression. <br />Water storage facilities consist of the primary 1,500-gpm on-site production well <br />located adjacent to the landfill entrance and a 500-gpm on-site production well <br />located by the RRF and Composting Facility. In addition, a water tank is located on <br />the south portion of the RRF and Compost Facility area. <br />In addition, measures are taken to provide adequate perimeter clearance or fire burn <br />as part of the landfills operation. Fires starting either on the landfill or the Compost <br />Facility would be hindered from spread to the other by the South Fork of South <br />Littlejohn’s Creek, which splits the property and these facilities and creating a natural <br />fire break. <br />4.2 WATER SUPPLY <br />There are four production water wells at the site. One well, located near the main <br />entrance facility was drilled to a depth of approximately 135 feet and groundwater <br />occurs at a depth of approximately 70 feet. The well was likely installed before the <br />opening of the landfill, having been previously used for agricultural purposes. It is <br />pumped at a rate of approximately 1,500 gallons per minute (gpm) at a maximum <br />frequency of approximately 27 times in a typical work day. Another well is located <br />south of the South Fork of South Littlejohn’s Creek in the southeast corner of the <br />RRF/Compost Facility area, and has a capacity of 500 gpm. The third well is located <br />along the northern boundary of the former Austin Road Landfill. This well was <br />installed in 1972 and has a production of approximately 60 gpm. The fact that <br />groundwater flow near the existing Forward Landfill is not modified by pumping from <br />this well suggests that it is screened in a confined unit below the uppermost <br />groundwater units that are monitored at the site. The fourth production well is <br />located along the eastern boundary of the site, just south of the entrance to the <br />RRF/Compost Facility. The locations of the wells located in the RRF/Compost Facility <br />area is shown on Figure 1. <br />These water supplies are available for initial mixing of the compost to bring the water <br />content up to desired levels, and wetting of the compost. Additional on-site water <br />uses include site construction and waste disposal operations, RRF and compost <br />operations, dust control, compaction, irrigation, equipment maintenance operations, <br />sanitary facilities, firefighting, and emergency situations. Bottled water is provided <br />for drinking. <br />4.3 EQUIPMENT <br />The equipment available at the facility is presented on Table 8 of the RCSI. <br />Additional equipment, such as Windrow turning equipment and temperature and <br />moisture probes, will be used, as needed, to meet the requirements of the compost <br />operation standards, including minimization of odors. Facility equipment will be <br />maintained according to standard maintenance practice and the manufacturer's <br />recommendations. Extra equipment is stored in the equipment maintenance area
