4. Use alternative fueled or catalyst equipped diesel construction equipment,where reasonable available, <br /> such as equipment capable of using biodiesel or emulsified fuel. Alternative fuels and NOx reduction <br /> equipment should be ARB-certified. <br /> 5. Limit the hours of operation of heavy duty equipment and/or the amount of equipment in use at any one <br /> time. <br /> 6. Curtail construction during periods of high ambient pollutant concentrations; this may include ceasing of <br /> construction activity during the peak-hour of vehicular traffic on adjacent roadways or on Spare the Air <br /> Days. <br /> 4.3.4 LEVEL OF SIGNIFICANCE AFTER MITIGATION <br /> Implementation of Mitigation Measures 4.3-1A and D would result in the required minimum 20%reduction in <br /> NOx emissions and a 45%reduction in PMIo emissions from heavy-duty diesel equipment, as compared with <br /> statewide average emissions. In addition, implementation of these measures would also result in a 5%reduction in <br /> ROG emissions from heavy-duty diesel equipment. All or part of the reductions may result from on-site <br /> equipment and fuel selection;the remainder would result from off-site reductions achieved through the payment <br /> of fees. Implementation of these measures would reduce temporary, short-term, construction-related emissions of <br /> ROG and NOx generated by the proposed project,but not to a less-than-significant level, as emissions would still <br /> exceed SJVAPCD's significance thresholds.As a result,this impact(generation of construction-related NOx <br /> emissions)would remain significant and unavoidable. <br /> With respect to fugitive PMIo dust emissions, implementation of Mitigation Measures 4.3-113 and C would ensure <br /> compliance with Regulation VIII,which is required by law, and include additional SJVAPCD-recommended <br /> control measures. As a result,this impact(generation of construction-related fugitive PMIo dust emissions)would <br /> be reduced to a less-than-significant level. <br /> With respect to Impact 4.3-5,"Exposure of Sensitive Receptors to Odors,"design of the WQCF would <br /> incorporate all feasible odor control technologies to reduce the potential for the exposure of sensitive receptors to <br /> odors. However, at this time it is not possible to determine if these measures would reduce the number of <br /> complaints to less than one per year averaged over three years.No further odor reduction measures are feasible. <br /> The impact would remain significant and unavoidable. <br /> Manteca WQCF and Collection System Master Plans EIR EDAW <br /> City of Manteca 4.3-29 Air Quality <br />
