3-18 <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.g . <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. <br />3.6.3 Noise Control <br />Deseribe how noise will be controlled to prevent hea/tI~ hazards to persons using the facility ' <br />and to nearbJ < resldents. /nclude a statement as to whether noise from facility opOFations is <br />lik-ely to create hea#h haralvs to persons using the site aRel/or to nearbj' residents. indicate <br />whether nearby residents ha ~(e COfRplained about noise from facility opefDtions. /f noise <br />meastJl'ements representati~'O ot facility ' operations hm'O been conducted. submit a copy of <br />th e results. <br />Noise at the site includes traffic noise generated by trucks and other vehicles travelling <br />alongoo Austin Road to the landfill and RRFjCompost Facility and noise generated by the <br />equipment used in RRFjCompost Facility operations. Noise levels of onsite equipment are <br />controlled by proper maintenance of mufflers to factory specifications. Noise levels have not <br />been a problem at the site, based on the absenoe of f o rma l oomplaints. The EHD will be <br />contacted should the site receive any noise complaints. Additionally . there shall be no <br />ancilla ry or facility operations (i.e .. heavy equipment operations within 1 ,500 feet of any <br />occupied residence ) outside of the permitted hours of operation. <br />Noise leve ls are not likely to create health hazards to persons using the site due to the use <br />of mufflers on heavy equipment. Protective ear wear is provided to all employees. Due to <br />the remote location of the site, noise levels are not likely to create hea lth hazards to nearby <br />residents. The EHD will be contacted should the site receive any complaints. <br />Forward Composting Facility SWT Engineering <br />Report of Composting Site Information -May 2014 <br />z:\,projects \allied waste \forward\resource recovery facility\5 yr permit rvw 2013-14\rcsi 2014\text\sec 3 -revtr.doc
