Estates Reservoir Replacement Draft Environmental Impact ReportAir QualityThe Project specifications shall include 17 CCR Section 93115, AirborneToxic Control Measure for Stationary Compression Ignition Engines, whichspecifies fuel and fuel additive requirements; emission standards foroperation of any stationary, diesel-fueled, compression-ignition engines; andoperation restrictions within 500 feet of school grounds when school is insession;A schedule of low-emissions tune-ups shall be developed and such tuneupsshall be performed on all equipment, particularly for haul and deliverytrucks; andLow-sulfur ( 15 ppmw S) fuels shall be used in all stationary and mobileequipment.TABLE 3.7-10Estimated Fugitive Dust Emissions from DemolitionArea Schedule Control Uncontrolled ControlledDemolition PhaseAcres Days Percent lbs/day lbs/yr lbs/day lbs/yrReservoir Area 2.25 100 95% 140 14,050 7.0 702Access Road 0.50 125 95% 26 3,188 1.3 159Building Demolition (cu ft vol) 1,090,000 100 75% 5 458 1.1 114Totals 171 17,695 9.4 976Source: BAAQMD Ref: AP-42 Chapter 13.2.3 “Heavy Construction Operations”Fugitive dust (as PM 10 ) 0.00042 lb/cu ft of building volume unmitigated, BAAQMD CEQA Guidelines, Section 3.3Fugitive dust (as PM 10 ) 51 lb/acre-day unmitigated, BAAQMD CEQA Guidelines, Section 3.3Mitigation Ref.
