San Joaquin County Community Alternatives Analysis Development Department No-Project Alternative The State CEQA Guidelines(Section 15126[e])require consideration of a No- Project Alternative that represents the existing conditions, as well as what would reasonably be expected to occur in the foreseeable future if the Project were not approved. For purposes of this analysis, it is assumed that,under the No-Project Alternative,the project area would remain in agricultural production and no mining would occur on the project site. Off-Site Processing of Materials Alternative Under this alternative,processing facilities consisting of an aggregate processing plant,asphalt concrete plant,portland cement concrete plant,and recycling plant, which encompass approximately 10 acres,would be located off site at an existing facility. Gnly excavation of the quarry would occur at the project site. The project site would be mined, and marketable sand and gravel would be loaded and hauled off site to an existing processing plant. Mobile diesel trucks would be used to transfer materials from active pits to the plants. The number of truck trips would be the same as for the proposed Project but would require additional miles of travel that would depend on the location of the selected existing processing plant. Mitigated Design Alternative Under this alternative, the temporary and permanent plant site would be sited at the southern limits of the property(Figure 4-1). This alternative was designed by the applicant to mitigate the diesel emissions previously predicted to affect the easterly residence due to the access road proximity. The access road in the mitigated design alternative has been moved approximately 2,000 feet to the south. The temporary plant would be used while initial mining is completed in the South Pit,then the permanent plant would be constructed on backfilled area within the pit,probably below grade. The asphalt and concrete plants would not be installed at the temporary plant. Similarly, construction of the mine shop/fueling area would await the permanent plant site development. Impacts of Proposed Alternatives No-Project Alternative �. Under this alternative,the existing physical conditions of the site would continue as described in the"Environmental Setting"section of each topic discussed in DeSilva Gates Quarry Project Draft Environmental Impact Report 4_3 J85 05105.05
