As previously discussed in Section 1.2.1. H here are three agriculture water <br />wells at the site. One well . located near the main entrance facility was drilled to a depth of <br />approximately 135 feet and groundwater occurs at a depth of approximately 70 feet. This <br />well was likel y installed before the opening of the landfill. having been previously used for <br />agricultural purposes . It is pumped at a rate of approximately 1500 gallons per minute <br />(gpm ) at a maximum frequency of approximately 27 times during a typical work day . <br />Another well is located south of the South Fork of South Littlejohn's Creek . in the southeast <br />corner of the Compost Facility/RRF area . and has a capacity of 500 gpm. The third well is <br />located along the northern boundary of the landfill. This well was installed in 1972 and has <br />a production of approximately 60 gpm. The fact that groundwater flow near the Forward <br />Landfill is not modified by pumping from this well suggests that it is screened in a confined <br />unit below the uppermost groundwater units that are monitored at the site. One domestic <br />well is located along the eastern boundarv of the site , just south of the entrance to the <br />Composting Facility /RRF. The locations of the wells located in the RRF /Compost <br />FacilitvtRB€ area are shown on Figure 2. A 2,000 gpm 'Ne ll at t he landfill en t ranee f acil ity, a <br />1 ,000 gpm well for fire and dust control at t he rear of the RRF, and a 20 gpm for domest ie <br />use loeated in the fron t of the faCility. There wi ll be an app rox imate ly 8,000 gallon "'later <br />tanl< in the South Area near t he Compost Fa cility operat ions area. In addition, water is <br />available from the storm water runoff sedimentation basins . however this alternative is not <br />currently utilized at the site reten t io n pond . For additional information . refer to Section <br />3 .5.2. <br />These water supplies are available for initial mixing of the compost to bring the water <br />content up to desired levels, wetting of the compost, dust control, and other applications <br />through use of on-site water trucks. <br />Preprocessing. Preprocessing and initial handling of feedstocks is also common to the <br />alternatives. Materials with large particle sizes such as wood waste, green material and <br />agricultural wastes may require grinding before use as feedstock and compostlng. All <br />incoming feedstock is spread out for manual screening before being stockpiled. These <br />materials will be handled in the manual sorting receiving area of the Compost Facilityffi....tt:le <br />exist ing RRF and ground using a tubt he exi st ing grinder. Additional grinding capacity will be <br />added, as necessary, to handle the required volume of green and wood waste material <br />received at the facility. Green material high in grass will be mixed as soon as possible with <br />ground wood waste and/or recycled compost and/or other relatively dry and low C:N <br />feedstock to minimize odor production. <br />MSVi preproeessing depends on t he f i nal use of the eomposted product. Li ttle or no <br />preprocessing is requ ired if the compost is to be directly landfilled or used for lan dfill cover . <br />Any MS W that is mixed in with the curbside greenwaste is removed before composting. In <br />addition . Rremova l of large objects is necessary to prevent damage to Windrow turning <br />equipment and grinding will aid decomposition during composting. Low t ech nology windrow <br />composting of MSW has been successfully imp leme nted in the U.s . If a higher quality <br />product is desired , more extensive pre-processing 4s-may be necessary. This could consist <br />of manual picking of metal, plastics and glass from the incoming material or receipt of clean <br />source-separated waste. <br />Forward Composting Facility SWT Engineering <br />Report of Compostlng Site Information -May 2014 <br />z:\projects\al li ed waste \forward \resource recovery facility\5 yr perm it rvw 2013·14\rcsi 2014\text \sec 2 -revtr.d oc
