<br />Legacy Sunflower Apartments Page 44 <br />Mitigated Negative Declaration – March 14, 2019 <br /> <br />section provides an analysis of potential long-term air quality impacts due to regional air quality and <br />local air quality impacts with the on-going operations of the project. <br /> <br />Mobile Sources <br /> <br />Mobile sources generate air emissions due to project vehicle miles traveled. Information from the traffic <br />study was referenced to provide the input data necessary for the CalEEMod model. Emission factors <br />for each vehicle trip was provided by the EMFAC2014 model to determine the vehicular traffic pollutant <br />emissions to calculate mobile source emissions. <br /> <br />Area Sources <br /> <br />Area source emissions include emissions from consumer products, landscape maintenance equipment <br />and architectural coatings. Landscape maintenance equipment emissions include fuel combustion <br />emissions from the operation of equipment such as lawn mowers, rototillers, shredders/grinders, <br />blowers, trimmers, chain saws, and hedge trimmers, as well as air compressors, generators, and <br />pumps. Because specific landscape equipment fleet information was not known, CalEEMod defaults <br />were used to estimate the emissions from the operation of the landscaping equipment that would <br />typically be used for a project as proposed. <br /> <br />Energy Usage <br /> <br />Energy usage includes air emissions from the generation of electricity and the use of natural gas by the <br />project. The project is required to comply with 2016 Title 24 standards. <br /> <br />Regional Air Quality Impacts <br /> <br />The worst-case long-term operational air emissions of the project are summarized in Table 8. As <br />shown, the long-term operational emissions of the project do not exceed SCAQMD thresholds for the <br />studied emissions. Therefore, the operational air quality impacts of the project are less than significant. <br /> <br />Table 8 <br />Regional Operational Pollutant Emissions1 <br /> <br /> <br /> <br /> <br />(1) Source: CalEEMod Version 2016.3.2; the higher of either summer or winter emissions. <br />(2) Area sources consist of emissions from consumer products, architectural coatings, and landscaping equipment. <br />(3) Energy usage consists of emissions from generation of electricity and on -site natural gas usage. <br />(4) Mobile sources consist of emissions from vehicles and road dust. <br /> <br /> <br />Activity Pollutant Emissions (pounds/day) <br />ROGs NOx CO SO2 PM10 PM2.5 <br />Area Sources2 6.98 3.59 20.15 0.02 0.38 0.38 <br />Energy Usage3 0.08 0.65 0.28 0.00 0.05 0.05 <br />Mobile Sources4 1.82 7.51 24.92 0.10 8.98 2.45 <br />Total Emissions 8.88 11.75 45.35 0.12 9.41 2.88 <br />SCAQMD Thresholds 55 55 550 150 150 55 <br />Exceeds Threshold?
