The Noise Study conducted as part of the EIR in 1993 did not study actual site <br />conditions. The study included information from other facilities that were similar and <br />extrapolated the information to reach a conclusion regarding noise from site operations. <br />The main reason for this was because the facility did not exist. A noise study needs to be <br />conducted to study actual site conditions. <br />2. Based on EIR noise levels were measured only at three locations (see EIR, 1993, p.76, <br />Table 4.6.3) at the north and west of the facility. <br />Noise monitoring should include locations in all directions of the facility consider <br />proposed expansion and relocation of the mixed C&D Processing facility to the south of <br />the MRF. <br />3. The proposed project includes increased hours of operation, facility outdoor activity, <br />and increased traffic and tonnage that should also be considered in the noise analysis. <br />It also concluded that that operations under the proposed project during the hours <br />between 6 am and 7 am, and between l Opm and 10:30pm fall into the category of <br />nighttime hours for San Joaquin County General Plan. <br />Only the Lonestar Aggregate Plan in Sacramento and the Noise Element from the County <br />of Sacramento General Plan has been used to consider 80dB Ldn conditionally acceptable <br />for agricultural and industrial lands (see EIR for San Joaquin County General Plan). <br />Minimize noise impacts on neighboring noise sensitive areas. <br />4. The existing noise study did not address any activities inside the Transfer Station/ <br />Material Recovery Facility (TS/MRF) because it is fully enclosed. The TS/MRF often <br />times operates with the doors open. Even if the doors are maintained closed during the <br />nighttime hours there will be some site equipment that will be used (forklifts and loaders) <br />to move the processed recyclables in and out. The forklifts and loader are equipped with <br />
