used to calculate emissions from the prototype construction equipment fleet and schedule <br />anticipated by CalEEMod for a residential land use consisting of 254 condo /townhouse units and <br />2,400 square feet of retail space as shown below. The equipment fleet shown is CalEEMod's <br />default fleet a project of this size. <br />CalEEMod Equipment Fleet <br />Demolition 72,000 sf (20 Days) <br />2 Excavators <br />2 Dozers <br />I Concrete Saw <br />Grading 2,017 CY Export <br />(30 (lays) <br />I Excavator <br />I Dozer <br />I Grader <br />3 Ttxctor /Loader /Backhoes <br />Construction (230 (lays) <br />I Crane <br />3 Forklifts <br />I Generator Set <br />3 Tractor /Loader /Backhoes <br />I Welder <br />Paving <br />(20 days) <br />2 Pavers <br />2 Paving equipment <br />2 Rollers <br />Utilizing this indicated equipment fleet the following worst case daily emissions were calculated <br />by CaIEEMod. The off -road equipment emissions load factors were adjusted in CalEEMod to <br />account for a 33 percent reduction attributable to overestimation of load factors, which CARB <br />has indicated to be appropriate,l <br />Construction Activity Emissions <br />Maximum Daily Emissions (pounds /day) <br />Maximal Construction <br />Emissions <br />ROG <br />NOx <br />CO <br />SO= <br />PM -10 <br />PM -2.5 <br />2014 <br />Unmitigated <br />6.1 <br />49.3 <br />32.9 <br />0.1 <br />14.2 <br />5.2 <br />Mitigated <br />6.1 <br />49.3 <br />32.9 <br />0.1 <br />11.6 <br />3.2 <br />2015 <br />Unmitigated <br />51.6 <br />1 27.4 <br />1 31.6 <br />1 0.1 <br />1 4.7 <br />2.0 <br />' In September 2010, the CARB announced that its methods used to estimate the load factor for off -road equipment <br />were incorrect and led to an overestimate of emissions by a factor of 33 percent. CARB is currently revising their <br />emissions model, a modified OFFROAD which has not yet been released. CalEEMod is based on the historical <br />OFFROAD. <br />I'm EI- S1 AQ -5 <br />75A -166 <br />
