Nitrous Oxide <br />A. Direct Sources <br />A1. Mobile Source (Construction Equipment) <br />Emissions of nitrous oxide from construction equipment are not reduced by any mitigation measures; therefore, emissions of nitrous oxide from <br />construction equipment equal to 0.00tons/yr. <br />A2. Mobile Source (Motor Vehicles) <br />Emissions of nitrous oxide from motor vehicles are calculated using the following equation: <br />-1-1 <br />Y = (M)*(E)*(C)*(C) <br />MAM12 <br />Y = mitigated annual emissions of nitrous oxide from motor vehicles, tons/yr. <br />MA <br />M = mitigated annual mileage for motor vehicles, miles/yr (URBEMIS 2007 9.2.2 output file). <br />M <br />E = emission factor for motor vehicles, gr/mile (USEPA Direct Emissions from Mobile Combustion Sources, Climate Leaders, 2004). <br />C = conversion factor from gr to lbs, 453.59 gr/lbs. <br />1 <br />C = conversion factor from lbs to tons, 2,000 lbs/ton. <br />2 <br />Red = Promote ride sharing programs for all tenants:Non-Residential Land Uses Transportation only; Reduction = %reduction*%vehicle emissions from total use (?% reduction) <br />1 <br />Red = Provide Adequate bicycle parking near building entrances: Non-Residential Land Uses Transportation only; Reduction = %reduction*%vehicle emissions from total use (?% reduction) <br /> <br />2 <br />Red = Idling is limited to less than 5 minutes: Non-Residential Land Uses Transportation only; Reduction = %reduction*%vehicle emissions from total use (?% reduction) <br />3 <br />*Note all reductions are accounted for in Urbemis. <br />E, gr/mile <br />Unit TypeM, miles/yrC, gr/lbsC, lbs/tonsY, tons/yr <br />M12M <br />A <br />Non cat passenger car0.000.0166453.592,0000.00 <br />Cat passenger car72915853.920.0518453.592,0004.16 <br />Diesel passenger car0.000.0161453.592,0000.00 <br />Non cat light-duty truck0.000.0208453.592,0000.00 <br />Cat light-duty truck66231900.640.0649453.592,0004.74 <br />Diesel light-duty truck0.000.0483453.592,0000.00 <br />Non cat heavy-duty truck0.000.0480453.592,0000.00 <br />Cat heavy-duty truck5164721.080.1499453.592,0000.85 <br />Diesel heavy-duty truck3797852.630.0322453.592,0000.13 <br />Non cat motorcycles1215264.230.0073453.592,0000.01 <br />Cat motorcycles2582436.490.0073453.592,0000.02 <br />Total, tons/yr9.91 <br />Reduction percentage, %5.74 <br />Page 10 of 14 <br />A3.
