3-13 <br />Forward Composting Facility SWT Engineering <br /> Report of Composting Site Information - July 2014 <br />z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2013-14\rcsi 2014\text\sec 3.doc <br />Rodents and Insects. The Compost Facility/RRF receives minimal quantities of wastes that <br />may attract rodents and insects, thus minimizing the food and habitat. In addition, timely <br />removal of the wastes, and keeping the storage of waste overnight to a minimum, minimizes <br />the attraction and presence of rodents and insects. Forward has a professional pest <br />management company on retainer for advice and services, as needed. Insects have not <br />been a nuisance at the site. <br />Birds. Under normal operations, wastes are processed within 24 hours. Additionally, <br />nuisance birds will be controlled by reducing litter through the litter collection program. If <br />nuisance birds ever become an issue at the RRF/Compost Facility, the use of caps, kites, <br />and/or propane cannons may be utilized as control measures. In the event that caps or <br />propane cannons are utilized in the future as bird deterrents, noise levels will be monitored <br />and controlled in accordance with Section 3.6.3 of this RCSI. <br />Records of monitoring and any corrective measures taken to address infestations, should <br />they occur, are maintained at the RRF/Compost Facility. <br />3.6.2 Odor Control <br />Odor generation at composting facilities tends to fluctuate, rising at the start of composting <br />and dropping quickly. Prevention is the most desirable form of odor control. Process <br />monitoring of composting conditions, especially aeration, is necessary for odor control. <br />Research suggests that maintaining the oxygen level at 5 to 15 percent inside the compost <br />pile, controlling the moisture content, and maximizing the decomposition rate will serve to <br />minimize odors. <br />In general, odors are controlled by processing the wastes and removing them as soon as <br />possible after they have been brought into the RRF. Odor control procedures will be <br />implemented to prevent odor impacts. Efforts to prevent and reduce odors will include: <br />♦ Avoiding creating large stockpiles of incoming material <br />♦ Producing a homogeneous material with the proper moisture content <br />♦ Providing adequate aeration and agitation <br />♦ Incorporating careful control of processing temperatures to maintain the rate of <br />decomposition. Additionally, as required in 14 CCR, Sections 17863.4 and <br />18227(n), an Odor Impact Minimization Plan (OIMP) is included as Appendix E. <br />Odors are not anticipated from residue storage since residue will be stored for no more than <br />48 hours. If persistent odors are produced, additional odor control techniques that may be <br />implemented include: <br />♦ Maintaining a C:N ratio above 25:1 in initial mixes of high nitrogen materials; <br />♦ Placing a layer of cured compost over raw compost materials to act as an odor trap <br />and serve as insulation; and, <br />♦ Using an organic odor neutralizer. <br />Lastly, the remote location of the Compost Facility will minimize the impacts of any odors <br />generated at the site. The EHD will be contacted should the site receive any odor <br />complaints.
