3.6.3 Noise Control Describe how noise will be controlled to prevent health hazards to persons using the facility and to nearby residents. Include a statement as to whether noise from facility operations is likely to create health hazards to persons using the site and/or to nearby residents. Indicate whether nearby residents have complained about noise from facility operations. If noise measurements representative of facility operations have been conducted, submit a copy of the results. Noise at the site includes traffic noise generated by trucks and other vehicles travelling on Austin Road to the landfill and RRF and noise generated by the equipment used in landfill and RRF operations. Noise levels of onsite equipment are controlled by proper maintenance of mufflers to factory specifications. Noise levels have not been a problem at the site, based on the absence of formal complaints. However, one of the mitigation measures identified in the last EIR was to provide the landowner and tenant at 9640 Austin Road with the option of a constructing a sound wall on their property to reduce noise exposure both in the front yard and inside the house if they request it within 5 years after the approval of Use Permit U-91-12. Noise levels are not likely to create health hazards to persons using the site due to the use of mufflers on heavy equipment. Protective ear wear is provided to all employees. Due to the remote location of the site, noise levels are not likely to create health hazards to nearby residents. In general, the major sources of noise at the Compost Facility/RRF will be the grinder and the Windrow turner, if used. These machines typically produce sound levels in the range of approximately 85 to 90 decibels. Since the estimated sound level at 200 feet is approximately that of the human voice during normal conversation, noise should not be a health hazard to persons working approximately 200 feet from the equipment. A noise level study conducted for a tub grinder manufacturer shows the following sound pressure levels: within 50 feet, 85.2 decibels; within 100 feet, 78.4 decibels; and within 200 feet, 73.5 decibels. Due to the site's remote location, the noise produced will not create an offsite concern; therefore, no special noise control devices will be needed at the RRF. All onsite personnel will be provided with ear protection. 3.6.4 Dust Control Describe measures to minimize the creation of dust. Dust is controlled at the site by (1) proper maintenance of haul roads (paving, grading, and applying a dust suppressant) and (2) by limiting the speed of all on site vehicles to 10 miles per hour. Water can be sprayed to control dust further, if necessary. For dust control purposes, surface water runoff or on site well water will be applied to all main access and haul roads.
