C <br />Regulatory Background <br />Federal <br />There are no federal noise regulations applicable to the proposed project. <br />State <br />The California Environmental Quality Act (CEQA) in Appendix G, Significant Effects, states "A project will <br />normally have a significant effect on the environment if it will (p) increase substantially the ambient noise <br />levels for adjoining areas." <br />Local <br />San Joaquin County, in the Noise Section of the Public Health and Safety chapter in the General Plan <br />2010, sets forth policies related to community noise. Policy 1 states that an exterior noise level of 65 dB <br />Ldp or less is considered acceptable for residential development. While this policy specifically addresses <br />the siting of new housing in noisy areas, it also establishes a benchmark of acceptability for residences <br />in San Joaquin County. Policy 4 states that development shall be planned and designed to minimize <br />noise impacts on neighboring noise sensitive areas. These policies are the only local standards directly <br />applicable to this project. <br />Existing Noise Environment <br />The proposed project is called the Tracy Materials Recovery and Transfer Facility (TMRF). The preferred <br />site for the TMRF is a 39.2 -acre parcel located on the west side of MacArthur Drive, south of Linne Road. <br />Receptors sensitive to noise from the proposed project include the residents of two mobile homes located <br />about 600 feet north of the site, who would be sensitive to both on site -generated noise and truck traffic, <br />and residents located north of Linne Road along MacArthur Boulevard who could be affected by increased <br />vehicular traffic noise. <br />® The existing noise environment in the vicinity of the project site results from gravel operations north and <br />west of the project site, truck traffic on MacArthur Boulevard, and general aviation aircraft. Noise levels <br />were measured at three locations in order to quantify existing baseline noise levels for the preferred site. <br />The measured data are summarized in Table 4.6.3. <br />''J <br />ER -93-1 -78- (9-27-93) <br />
