San Joaquin County Community Executive Summary Development Department limitations,jurisdictional boundaries, and whether the project applicant can reasonably acquire,control, or otherwise have access to the alternative site. In addition to the proposed Project,this EIR analyzes several alternatives: a No Project—No Mining Alternative, Off-Site Processing Operations Alternative, and a Mitigated Design Alternative. These alternatives and their environmental effects are described in more detail in Chapter 4, "Alternatives Analysis" No Project Alternative Under the No Project—No Mining Alternative,neither the proposed project,nor the alternatives discussed below would be constructed. This altemative assumes that no construction activities would occur at the site and that there would be no amendments to the existing General Plan or zoning designations. This alternative is included to allow for comparison of the impacts caused by approving the Project with the impacts that would result if it were not approved and the site not developed. Off-Site Processing Operations Alternative The proposed action includes processing facilities consisting of an aggregate processing plant, asphalt concrete plant,Portland cement concrete plant and recycling plant. The processing area would encompass approximately 10 acres. Under this alternative, these plant processes would occur at an existing facility location. Only excavation of the quarry would occur at the proposed project site. Mining activities would occur and marketable sand and gravel would be loaded and hauled off-site to the existing processing plant. Mobile diesel trucks would be used to transfer materials from active pits to the plants. This alternative would require additional miles of travel that would depend on the location of the selected existing processing plant. Furthermore,the mined material contains as much as 20%waste fines compared to finished product and would require additional truck trips to be hauled offsite. Following processing, these waste fines would be hauled back to the site to backfill and reclaim the site. Therefore, this alternative would result in an estimated 40% increase in the number of truck trips, compared to the proposed project. The primary purpose of this alterative is to prevent significant and unavoidable noise impacts on sensitive receptors adjacent to the proposed quarry. Reduced Mining Alternative Under this alternative, the temporary and permanent plant site would be sited at the southern limits of the property. 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.
