3-19 <br />In general, the major sources of noise at the Compost Facility/RRF will be the grinder and <br />the Windrow turner, if used. These machines typically produce sound levels in the range of <br />approximately 85 to 90 decibels. Since the estimated sound level at 200 feet is <br />approximately that of the human voice during normal conversation, noise should not be a <br />health hazard to persons working approximately 200 feet from the equipment. A noise level <br />study conducted for a tub grinder manufacturer shows the following sound pressure levels: <br />within 50 feet, 85.2 decibels; within 100 feet, 78.4 decibels; and within 200 feet, 73.5 <br />decibels. <br />It should be noted that noise produced at the facility also complies with provisions of the <br />San Joaquin County Development Code, Title 9, Section 9-1025.9 as specified in SWFP No. <br />39-AA-0020. <br />Due to the site's remote location, the noise produced will not create an offsite concern; <br />therefore, no special noise control devices will be needed at the RRF/Compost Facility. <br />3.6.4 Dust Control <br />DesCfibe measl:Jres to mlR /mire the croat/OR of dust (1 4 CCR, Sect/OR 18227(d». <br />Dust is controlled at the site by (1) proper maintenance of haul roads (paving, grading, and <br />wateringapplying a dust suppressant)J......aRG (2) application of fine water spray (dictated by <br />the weather conditions and /or on an as -needed basis ) on the active soil -covered work areas. <br />soil excavation areas. and soil stockpile areas where conditions may result in fugitive dust: <br />(3 ) application of organic dust suppressant. and (4}----ey limiting the speed of all on :site <br />vehicles to less than those that would cause visible dust emissions behind the vehicle.u> <br />mi les per hour. Water can be sprayed to control dust further, if necessary. For dust control <br />purposes, surface water runoff or on :site well water wi ll be is applied to all main access and <br />haul roads at least once per day. All -weather surfacing is applied to any unpaved road <br />segment that carries 50 or more vehicle trips per day continuously for more than 30 days. <br />Dirt roads and areas between active compost arewill be watered, as necessary, to minimize <br />dust when equipment uses the roads/areas. Proper management of the moisture level of <br />the compost materials throughout the operation will minimize dust generation. The <br />likelihood of dust problems from the initial receiving, grinding, and compost pile formation <br />and turning is low. The active compost wi ll beis monitored for moisture content, and water <br />w i ll beis added when needed. <br />Dust generation at composting facilities occurs primarily during screening operations. In <br />order to mitigate this, the trommel screen may be equipped with canvas covers or water <br />mist to minimize fugitive dust. Compost facility operating personnel wi ll beare provided with <br />goggles and respirators. <br />3.6.5 Litter Control <br />Describe the plaRRed collection IFequenc), of litter and loose materials to meet the of:ijective <br />OfpF(NontiRg the aCBl:Jmtilation of ql:JDntities which are aesthotieallj' objeetionablo or cal:Jse <br />otherproblems (14 CCI?, SeetiOR 18227(d». <br />Forward conducts an extensive litter collection program on a daily basis to minimize the <br />impact of litter on the site and on the surrounding area. Landfill personnel regularly patrol <br />the landfill perimeter and pick up litter blown from the working area on a daily basis. If <br />additional assistance is required beyond site personnel. temporary laborers will be hired. <br />Forward Compostlng Facility SWT Engineering <br />Report of Compostlng Site Information -May 2014 <br />z:\projects\aliied waste \forward \resource recovery facility \5 yr perm it rvw 2013-14\rcsi 2014\text\sec 3 -revtr .doc
