Cabrillo at First Mixed-Use Residential Air Quality, Global Climate Change, HRA, and Energy Impact Analysis 35 19386 LONG-TERM OPERATIONAL EMISSIONS The on-going operation of the proposed project would result in a long-term increase in air quality emissions. This increase would be due to emissions from the project-generated vehicle trips and through operational emissions from the on-going use of the proposed project. The following section provides an analysis of potential long-term air quality impacts due to: regional air quality and local air quality impacts with the on- going operations of the proposed project. Operations-Related Regional Air Quality Impacts The potential operations-related air emissions have been analyzed below for the criteria pollutants and cumulative impacts. Operations-Related Criteria Pollutants Analysis The operations-related criteria air quality impacts created by the proposed project have been analyzed through the use of the CalEEMod model. The operating emissions were based on the year 2023, which is the anticipated opening year for the proposed project. The operations daily emissions printouts from the CalEEMod model are provided in Appendix B. The CalEEMod analyzes operational emissions from area sources, energy usage, and mobile sources, which are discussed below. Mobile Sources Mobile sources include emissions from the additional vehicle miles generated from the proposed project. The vehicle trips associated with the proposed project have been analyzed by inputting the project-generated vehicular trips (trip generation rate) from the Cabrillo at Frist Mixed-Use Residential Trip Generation & Vehicle Miles Traveled Assessment (TIA) prepared by Ganddini Group, Inc. (January, 2022) into the CalEEMod Model. The Trip Generation Analysis found that the proposed project would create approximately 236 vehicle trips per day with a weekday trip generation rate of 6.74 trips per dwelling unit per day. The Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition, 2021) is now available; however, CalEEMod utilizes the 10th Edition of the ITE Trip Generation Manual. Therefore, in order to be consistent with the Trip Generation Analysis, the Saturday trip generation rate was changed to 4.55 trips per dwelling unit per day and the Sunday trip generation rate was changed to 3.86 trips per dwelling unit per day per the 11th Edition of the ITE Trip Generation Manual. The program then applies the emission factors for each trip which is provided by the EMFAC2017 model to determine the vehicular traffic pollutant emissions. Area Sources Per the CAPCOA Appendix A Calculation Details for CalEEMod, area sources include emissions from consumer products, landscape equipment and architectural coatings. Landscape maintenance includes fuel combustion emissions from equipment such as lawn mowers, rototillers, shredders/grinders, blowers, trimmers, chain saws, and hedge trimmers, as well as air compressors, generators, and pumps. As specifics were not known about the landscaping equipment fleet, CalEEMod defaults were used to estimate emissions from landscaping equipment. No changes were made to the default area source parameters. Energy Usage Energy usage includes emissions from the generation of electricity and natural gas used on-site. No changes were made to the default energy usage parameters. Project Impacts The worst-case summer or winter criteria pollutant emissions created from the proposed project’s long-term operations have been calculated and are shown below in Table 9. The results show that none of the SCAQMD 356/27/2022 Planning Commission 2 –88
