2-8 <br />types and quantities of materials received and the quality requirements of the final compost <br />product. An area of over 9 ac res is a llowed fo r th is operation. <br />The existing conditions plan, legal property limits, and topography are shown in Figure 24. <br />Except for some setbacks, internal roads, the South Fork easement, and County of San <br />Joaquin right of way for Austin Road, virtually the entire South Area will be is developed for <br />composting (including some of the area now occupied by the RRF). The easement and right <br />of way are shown in Figure 24. A detailed Site Plan, including the unloading, storage, <br />processing, parking and loading areas, and ancillary facilities, is shown on Figure s 2±;-4A <br />and Q7 . <br />Storage Areas. To the extent feasible. +lhe incoming compostable materials will beare mixed <br />into compost piles the same day as received. The storage time of compost feedstock wtH <br />ee is 48 hours. <br />Parking Areas. Visitor and employee parking are on the east side of the RRF building as <br />shown on Figure 56+. <br />Processing Areas. The Compost Facility wtl+-include ~ areas for receiving, precompost <br />processing, post-processing, and compost storage. Non-processible materials will be hauled <br />ElaHy-to the Forward Landfill for disposal. Figure 24 includes a general dimension of the <br />unloading, storage, processing, parking, and loading areas. Design calculations for th isese <br />area s-arej§ included in Appendix .6A . <br />Prevention of the Propagation of Vectors and the Creation of Nuisances. The site will be <br />graded as shown on the grading plan (Figure 6+€;) to promote drainage of surface water <br />from all areas of the site into two ditches that drain to a sedimentation basinretention pond . <br />The site will be constructed of compacted native earth. Onsite soils are silt and clay, and will <br />provide a relatively impermeable surface. The site will be graded relatively smooth allowing <br />complete removal of deposited feedstock. Feedstock such as food proceSSing residue will <br />be incorporated immediately into compost piles to minimize the chance of vector attraction <br />and reproduction aooas well as for odor minimizationproduotion . Semi-solid and liquid <br />feedstocks will be added to other feedstocks at a rate to meet the composting mixture <br />moisture criteria, thus minimizing the potential for leachate formation. Semi-solid and liquid <br />feedstocks will be incorporated immediately into compost piles to minimize the chance of <br />vector attraction and reproduction as well as the generation of potential---i3f\G odor~ <br />production . Other highly putresible wastes such as grass will also be incorporated <br />immediately into compost to minimize the chance of vector attraction and reproduction and <br />odor production. All feedstocks will be mixed in proportions that promote efficient <br />composting, aerobic conditions, and minimize ammonia odor release. <br />Turning will be scheduled to provide compliance with pathogen reduction requirements and <br />maintain aerobic conditions. <br />Water Usage. Water will be added to the piles, as necessary, before turning to ma i ntain <br />efficient composting. Water will also be used to control dust from the compost pad and <br />various composting operations, such as grinding and screening as determined from <br />experience . <br />Forward Compostlng Facility SWT Engineering <br />Report of Composting Site Information -May 2014 <br />z:\projects \allied waste \forward \resource recovery facility \5 yr perm it rvw 2013-14\rcs i 2014\text \se c 2 -revtr .doc
