6 OTHER CEQA REQUIRED SECTIONS <br /> 6.1 SIGNIFICANT UNAVOIDABLE ADVERSE IMPACTS <br /> CEQA Section 21100(b)(2)(A) states that an EIR shall include a detailed statement setting forth"in a separate <br /> section: any significant effect on the environment that cannot be avoided if the project is implemented."Chapter 4 <br /> of this DEIR provides a detailed analysis of all potential significant environmental impacts of the project, feasible <br /> mitigation measures that could reduce or avoid the project's significant impacts, and whether these mitigation <br /> measures would reduce these impacts to less-than-significant levels. Chapter 5, "Cumulative Impacts,"identifies <br /> the significant cumulative impacts of the project. If a specific impact cannot be reduced to a less-than-significant <br /> level, it is considered a significant and unavoidable impact. Significant unavoidable environmental impacts <br /> (direct, indirect, and cumulative) of the proposed project include: <br /> 6.1.1 PROJECT IMPACTS <br /> IMPACT 4.1-3: Land Use and Agricultural Resources—Conversion of Important Farmland to <br /> Nonagricultural Use. Implementation of the proposed project would result in the conversion of approximately 41 <br /> acres of Prime Farmland and Farmland of Statewide Importance to nonagricultural use. Conversion of agricultural <br /> land would be a significant impact. <br /> Implementation of Mitigation Measure 4.1-3 would substantially reduce the project's agricultural resource impact, <br /> but this measure would not eliminate the project's Important Farmland impact to a less-than-significant level. <br /> Therefore,this impact would be considered significant and unavoidable. <br /> IMPACT 4.3-1: Air Quality—Generation of Short-Term Construction-Related Emissions of Criteria Air <br /> Pollutants and Precursors.Modeled short-term project-generated emissions from construction equipment for <br /> projects constructed during Phase 1(2008 to 2010 based on construction projections presented in Table 3-4) <br /> would exceed SJVAPCD's significance threshold of 10 tpy and project applicable SJVAPCD-required and other <br /> control measures for fugitive dust are not currently part of the project description. Project-generated, construction- <br /> related emissions of criteria air pollutants and precursors could violate or contribute substantially to an existing or <br /> projected air quality violation, expose sensitive receptors to substantial pollutant concentrations, especially <br /> considering the nonattainment status of San Joaquin County, and/or conflict with air quality planning efforts. As a <br /> result,this impact would be significant. <br /> Implementation of Mitigation Measure 4.3-1 would result in the required minimum 20%reduction in NOx <br /> emissions and a 45%reduction in PM10 emissions from heavy-duty diesel equipment, as compared with statewide <br /> average emissions. In addition, implementation of this measure would also result in a 5%reduction in ROG <br /> emissions from heavy-duty diesel equipment, and would reduce temporary, short-term, construction-related <br /> emissions of ROG and NOx generated by the proposed project,but not to a less-than-significant level, as <br /> emissions would still exceed SJVAPCD's significance thresholds.As a result,this impact(generation of <br /> construction-related NOx emissions)would remain significant and unavoidable. <br /> IMPACT 4.3-5: Air Quality—Exposure of Sensitive Receptors to Odors.The WQCF is known to produce <br /> odors and there has been at least one confirmed compliant per year over a three year period.While the <br /> design of the project incorporates all feasible odor control technologies to reduce project-generated odors,it is <br /> unknown whether these technologies would limit odor complaints to less than one per year,which is the <br /> significance standard used by the SJVAPCD for significant odor problems.No other feasible odor control <br /> technologies are available to reduce the intensity of odors at the City of Manteca Wastewater Quality Control <br /> Facility(WQCF) site and that would guarantee that odor complaints would be limited to one per year. Therefore, <br /> this impact would be significant and unavoidable. <br /> Manteca WQCF and Collection System Master Plans EIR EDAW <br /> City of Manteca 6-1 Other CEQA Required Sections <br />
