operations. Therefore,the overall number of receptors would be reduced,but the remaining westerly receptors will still be impacted. Additionally, the westerly receptors could experience an increase in the number of nights with extended operating hours, as haul trucks headed to the east would still have to pass by on their way to McHenry Avenue. Consideration of Alternative 2 Both Alternatives 2 and 3 would reduce the number of residential noise receptors impacted,but increase the frequency for those particular receptors. However, it is likely that Alternative 3 would generate more additional effects,by increasing haul distances and potentially exposing additional receptors, including residents of Riverbank,to increased truck haul noise. Findings: The West Only Haul Route Alternative (Alt. 2), is the environmentally superior alternative as the number of residential noise receptors impacted would be reduced. However, it should be noted that for the individual receptors located west of the project site, the noise impacts experienced would be equal or greater than the Proposed Projects. Increased fuel consumption and additional impacts to air quality may occur under this alternative. Delivering material to the east would require increased haul distances, resulting in increased criteria pollutants and greenhouse gas emissions. Therefore, the Commission finds the West Only Haul Route Alternative is environmentally undesirable and is therefore rejected. East Only Haul Route Alternative Description This alternative would require all nighttime truck traffic to enter and exit the facility via eastbound E.River Road. Trucks would be required to utilize Santa Fe Road in order to reach E.River Road. This haul route reduces the significance of noise related impacts to sensitive residential receptors located west of the project site entrance along E. River Road. However, residences east of the project site entrance along E. River Road would still experience noise related impacts during nighttime operations. Distinctive Environmental Characteristics The following summarizes potential impacts of the east only haul route alternative and compares them to the impacts of the Proposed Project: Visual and Lighting The east only haul route alternative would result in the same impacts (less than significant)to visual resources as the Proposed Project. Traffic and Circulation Under this alternative all nighttime truck traffic would be required to enter and exit the Munn& Perkins facility via eastbound E. River Road. As the traffic analysis in the EIR assumes that all 17
