2-1 Forward Composting Facility SWT Engineering Report of Composting Site Information - July 2014 z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2013-14\rcsi 2014\text\sec 2.doc 2.0 COMPOST PROCESSING SITE DESIGN, MONITORING, AND SITE IMPROVEMENTS Composting operations will not occur on an existing or closed landfill; however, the Compost Facility is located on an area permitted for future WMUs. All composting operations will cease in this area when Forward begins development of the WMUs in this area. 2.1 Composting Site Design The design of the Compost Facility is discussed in the following sections. 2.1.1 Site Plan Onsite. This section describes the ancillary facilities for the site as a whole, inclusive of the Forward Landfill, RRF and Compost Facility. The RRF and Compost Facility are shown on Figure 2. Water. There are four production water wells at the Forward Landfill/RRF/Composting Facility site. One well, located near the main entrance to the landfill was drilled to a depth of approximately 135 feet and groundwater occurs at a depth of approximately 70 feet. This 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 1500 gallons per minute (gpm) at a maximum frequency of approximately 27 times during a typical work day. Another well is located south of the South Fork of South Littlejohn’s Creek, in the southeast corner of the RRF/Compost Facility area, and has a capacity of 500 gpm. The third well is located along the northern boundary of the landfill. This well was installed in 1972 and has a production of approximately 60 gpm. The fact that groundwater flow near the 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. The fourth production well is located along the eastern boundary of the site, just south of the entrance to the RRF/Compost Facility. The locations of the wells located in the RRF/Compost Facility area is shown on Figure 2. On-site water uses include site construction and waste disposal operations, the RRF and compost operations mainly utilize water for dust control, compaction, irrigation, equipment maintenance operations, sanitary facilities, fire fighting, and emergency situations. Bottled water is provided for drinking. Sanitary Facilities. There are no on-site sewage disposal system or leach lines. Portable toilets are provided at the site to provide sanitary facilities, which are serviced daily or as needed. Two portable toilets are located adjacent to the landfill office, two are located a t the RRF, two are in the maintenance yard, and two are located near the working face. Hand washing facilities are located in each portable toilet and an additional facility is located near the office trailer. The locations/quantities of portable toilets will change with daily operations as the site is developed. Electricity. PG&E provides primary electric service to the site. Electric power is provided to the office trailers and onsite pumping facilities. There is night/security lighting at the landfill and RRF/Composting Facility entrances. Communications. The telecommunications provider delivers telephone service to the site. The site offices and key site personnel have phones. The site has five telephone lines for
