4.1 – Air Quality Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.1-36 Operational Emissions The Project would involve construction of warehouse and office land uses and associated parking. Operation of the Project would generate ROG, NOx, CO, SOx, PM10, and PM2.5 emissions from mobile sources, including vehicle trips from passenger vehicles and heavy-duty trucks; area sources, including the use of consumer products, architectural coatings for repainting, and landscape maintenance equipment; energy sources, including combustion of fuels used for space and water heating; off-road equipment, including forklifts and a yard truck; and stationary sources, specifically the fire pump testing and maintenance. As discussed in Section 4.1.3, pollutant emissions associated with long-term operations were quantified using CalEEMod for area, energy, off-road, and stationary sources, and were primarily based on CalEEMod default values. Project-generated mobile source emissions were estimated in a spreadsheet using EMFAC2017 emissions factors and based on Project-specific trip rates. Fuel storage tank emissions were estimated using EPA TANKS 4.0.9d. Table 4.1-9 presents the annual area, energy, mobile, off-road, and stationary source emissions associated with operation (year 2022) of the Project. Details of the emissions calculations are provided in Appendix B. Table 4.1-9.

No Yes No No No No Notes: ROG = reactive organic gas; NOx = oxides of nitrogen; CO = carbon monoxide; SOx = sulfur oxides; PM10 = coarse particulate matter; PM2.5 = fine particulate matter; SJVAPCD = San Joaquin Valley Air Pollution Control District; <0.01 = reported value less than 0.01. See Appendix B for complete results. Totals may not sum due to rounding. Stationary sources consist of fuel pump testing and maintenance and diesel fuel storage tank. As shown in Table 4.1-9, the combined annual area, energy, and mobile source emissions would not exceed the SJVAPCD’s operational thresholds for ROG, CO, SOx, PM10, or PM2.5. However, the Project would exceed the SJVAPCD’s operational threshold for NOx, and impacts would be potentially significant. Ambient Air Quality Assessment The SJVAPCD recommends that an Ambient Air Quality Assessment be performed when on-site emissions of any criteria pollutant would equal or exceed any applicable threshold of significance for criteria pollutants or 100 pounds per day of any criteria pollutant (SJVAPCD 2015a). The maximum daily emissions during construction for ROG would occur during the overlap of building construction and architectural coating in 2022. Operational emissions generated on site would include area sources, energy sources, and off-road equipment. The majority of the mobile emissions would occur a distance from the Project site; therefore, localized impacts from mobile sources were assumed to include traveling 0.45 miles on site and 0.25 miles off site. The results of the screening analysis are presented in Table 4.1-10.
