5. ALTERNATIVES a+ adjacent and nearby rural residences in a greater number than at the proposed project site. This would result in a greater number of residences being impacted by an increase in ambient noise levels from the mining operations. Traffic noise would also increase on nearby roadways used to .. access the quarry. The off-site alternative would result in similar impacts as the proposed project, but to a greater number of residences in the area. Mitigation measures similar to those identified in Section 4.5 would be required. Air Quality The dust generated by project construction,the emissions generated by the mining and processing operations,and the diesel particulate emissions from stationary and mobile sources would be similar to the proposed project. The off-site alternative includes adjacent and nearby rural residences in a greater number than at the proposed project site. This would result in a greater number of residences being impacted by dust and other emissions from the mining operations and traffic. The off-site alternative would result in similar impacts as the proposed project, but to a greater number of residences in the area. The significant and unavoidable operations impact from NOx would be the same with this alternative as the proposed project. Mitigation measures similar to those identified in Section 4.6 would be required. r Geology and Soils/Mineral Resources " The slope instability, erosion, and seismic impacts associated with the off-site alternative would be similar to those of the proposed project. Mitigation measures similar to those identified in Section 4.7 would be required. Hydrology and Water Quality v The off-site alternative contains rural residential housing and agricultural crops that most likely use groundwater wells for domestic and irrigation uses. The off-site alternative has two creeks that cross the site in two different areas. Hydrology impacts would be increased with the off-site alternative if the creeks were to be mined out as in the proposed project Haul Route Option 2. This would result in a significant an unavoidable impact of altering the natural hydrology of these creeks,the same as the proposed project. Otherwise,the creeks would be avoided by providing a 100 foot buffer as in the proposed project Haul Route Option 1. All other hydrology and water quality impacts and the mitigation measures provided in Section 4.8, such as groundwater i, seepage in the mining excavations causing evaporation loss and threatening groundwater quality, potential spills of hazardous materials reaching the groundwater,potential for contaminants to enter the groundwater if excavation disturbs and/or truncates the existing groundwater well �. shafts, and groundwater extraction that could lower groundwater levels in areas beyond the site would be similar to the proposed project. Biological Resources The off-site alternative contains similar features as the proposed project, such as agricultural crop .., land,creek beds, and rural residential structures.
