NotwithstandingProject-generated impacts, maximum background levels of particulate matter(PM 10 , PM 2.5 ) already exceed state or federal standards as applicable in theProject vicinity. Therefore, the Project would incrementally contribute to theseexisting exceedences. The BAAQMD has developed emission control measuresfor construction emissions that, when implemented, reduce the impacts to lessthan significant. Also, the results of the screening risk assessment show that theprobability of contracting cancer from diesel particulate matter, for the Maximallysb09_001.doc 3-7.14 7/22/2009
Estates Reservoir Replacement Draft Environmental Impact ReportAir QualityExposed Individual during the construction phase is about 1.2 x 10 -6 , which is lessthan the 10 in 1 million (10 -5 ) BAAQMD CEQA threshold.Mitigation Measure: None Required.Measure 3.7-2a: The following diesel control measures will be incorporated byEBMUD into contract specifications:To minimize potential diesel odor impacts on nearby receptors (pursuantto BAAQMD Regulation 1, Rule 301, Nuisance), construction equipmentwill be properly tuned. A schedule of tune-ups will be developed andperformed for all equipment operating within the Project area, particularlyfor haul and delivery trucks. A log of required tune-ups will bemaintained and a copy of the log will be submitted to EBMUD for reviewevery 2,000 service hours.Fixed temporary sources of air emissions (such as portable pumps,compressors, generators, etc.) will be electrically powered unless thecontractor submits documentation and receives approval from EBMUDthat the use of such equipment is not practical, feasible, or available(generally contingent upon power line proximity, capacity, andaccessibility). California ultra-low sulfur diesel fuel with a maximumsulfur content of 15 ppm by weight, or an approved alternative fuel, willbe used for on-site fixed equipment not using line power. If sufficientpower line capacity is available, EBMUD will endeavor to rent (via thecontractor) an electrically-powered concrete crusher in lieu of a dieselpowered unit. This will eliminate emissions associated with combustionof approximately 1,800 gallons of diesel fuel.To minimize diesel emission impacts, construction contracts will requireoff-road compression ignition equipment operators to reduce unnecessaryidling with a two (2) minute time limit.On-road and off-road material hauling vehicles will shut off engines whilequeuing for loading and unloading for time periods longer that two (2)minutes.Off-road diesel equipment will be fitted with verified diesel emissioncontrol systems (e.g., diesel oxidation catalysts) to the extent reasonablyand economically feasible.Utilize alternative fuel equipment (i.e., compressed or liquefied naturalgas, biodiesel, electric) to the extent reasonably and economically feasible.Significance after Mitigation: Less than Significant.sb09_001.doc 3-7.15 7/22/2009
