It should be noted that all incoming loads are required to be covered with fLtarpllil or <br />mesh. In addition, on-site containers utilized to store waste and/or feedstock will be <br />are also covered to mitigate odors. <br />3.1 AERATION <br />Aeration is necessary for odor control. Maintaining the oxygen level at approximately <br />5 to 15 percent inside the compost pile will serve to minimize odors. <br />3.2 MOISTURE CONTENT OF MATERIALS AND MOISTURE MANAGEMENT <br />The specific mixtures for composting will be developed based on the availability of <br />feedstock, desired use of the product and the operating parameters outlined in this <br />permit application required for proper composting. The material received is <br />desc ribed listed in Section 1.0 as allowed under 14 CCR, Section 17852. <br />Grit/grease from wastewater treatment plants and restaurant grease traps , hold i ng <br />tanl { pump i ngs and sept i c tanl~ pumpingG may a lso be accepted . Composition and <br />residual moisture of the materials is dependent on the source of the feedstock and <br />time of year. Acceptance of these wastes depends on having sufficient dry compost <br />feedstock to absorb excess water. Water from these sources iswi ll be used to <br />replace use of on-site water to create initial compost mixture moisture content within <br />the desired range. The desired moisture content for composting mixtures for <br />optimum composting and minimum odor generation are as follows: <br />• Moisture content -approximately 50 to 60 percent <br />• Carbon to nitrogen ratio (C: N) -greater than approximately 25:1 <br />• Density -less than approximately 1,000 pounds per cubic yard <br />• Porosity structure -as necessary to maintain aerobic conditions <br />Moisture content will be monitored based on knowledge of incoming moisture <br />content, moisture addition, and by manual and laboratory testing. Piles will be <br />watered and/or turned based on the results of monitoring. All operating standards <br />defined by State composting regulations will be followed. <br />3.3 FEEDSTOCK CHARACTERISTICS AND QUALITY <br />The Compost Facility handles +the feedstock materials listed in Section 1.may <br />inslude green material, food process i ng residue , food waste, garbage, bioso lids, and <br />mixed sol id waste, as described in 14 GGR , Seot ion 17862. Incoming materials are <br />checked for physical contaminants. The load inspection process begins at the RRF. <br />All loads, except for specia l handling 'tYastes suoh as wood 'A'astes and \',<astes not <br />need i ng any preprocessing, are brough t to the RRF and separated . The loads are <br />spread out in the material sorting area (see Figure 1) bu il d ing and the entire load is <br />checked for recoverable mater ials, Gompostable materials , landfi ll mater ials , and <br />unacceptable or prohibited waste. Loads of material that have been processed prior <br />to arriving at the Compost Facility will be visually inspected to ensure that <br />contaminants are removed. <br />Feedstock such as food processing residue will be incorporated immediately into <br />compost piles to minimize the chance of vector attraction and reproduction and odor <br />production. Semi-solid and liquid feedstocks will be added to other drier feedstocks <br />Forward Compost Fac ility -OIMP 6 SWT Engineering <br />z:\projects\allied waste \forward V esource recovery facil ity\5 yr perm it rvw 2013-14V csi 2014\appendices \app e-oimp \oimp <br />text. doc; 5/16/2014
