Cabrillo at First Mixed-Use Residential Air Quality, Global Climate Change, HRA, and Energy Impact Analysis 92 19386 Construction Equipment Fuel Estimates Fuel consumed by construction equipment would be the primary energy resource expended over the course of project construction. Fuel consumed by construction equipment was evaluated with the following assumptions: ▪ Construction schedule of approximately 15 months ▪ All construction equipment was assumed to run on diesel fuel ▪ Typical daily use of 8 hours, with some equipment operating from ~6-7 hours ▪ Aggregate fuel consumption rate for all equipment was estimated at 18.5 hp-hr/gallon (from CARB’s 2017 Emissions Factors Tables and fuel consumption rate factors as shown in Table D-21 of the Moyer Guidelines: (https://www.arb.ca.gov/msprog/moyer/guidelines/2017gl/2017_gl_appendix_d.pdf). ▪ Diesel fuel would be the responsibility of the equipment operators/contractors and would be sources within the region. ▪ Project construction represents a “single-event” for diesel fuel demand and would not require on-going or permanent commitment of diesel fuel resources during long term operation. Using the CalEEMod data input for the air quality and greenhouse gas analyses (Sections 2 and 4 of this report), the project’s construction phase would consume electricity and fossil fuels as a single energy demand, that is, once construction is completed their use would cease. CARB’s 2017 Emissions Factors Tables show that on average, aggregate fuel consumption (gasoline and diesel fuel) would be approximately 18.5 hp-hr- gal. Table 24 shows the results of the analysis of construction equipment. As presented in Table 24, project construction activities would consume an estimated 29,799 gallons of diesel fuel. As stated previously, project construction would represent a “single‐event” diesel fuel demand and would not require on‐going or permanent commitment of diesel fuel resources for this purpose. Construction Worker Fuel Estimates It is assumed that construction worker trips are from light duty autos (LDA), light duty truck 1 (LDT1), and light duty truck 2 9LDT2) at a mix of 50 percent/25 percent/25 percent, respectively, along area roadways.41 With respect to estimated VMT, the construction worker trips would generate an estimated 156,864 VMT. Data regarding project related construction worker trips were based on CalEEMod 2020.4.0 model defaults. Vehicle fuel efficiencies for construction workers were estimated in the air quality and greenhouse gas analyses (Sections 2 and 4 of this report) using information generated using CARB’s 2021 EMFAC model (see Appendix D for details). An aggregate fuel efficiency of 26.38 miles per gallon (mpg) was used to calculate vehicle miles traveled for construction worker trips. Table 25 shows that an estimated 5,946 gallons of fuel would be consumed for construction worker trips. Construction Vendor/Hauling Fuel Estimates Tables 26 and 27 show the estimated fuel consumption for vendor and hauling during building construction and architectural coating. With respect to estimated VMT, the vendor and hauling trips would generate an estimated 23,787 VMT. Data regarding project related construction worker trips were based on CalEEMod 2020.4.0 model defaults. For the architectural coatings it is assumed that the contractors would be responsible for bringing coatings and equipment with them in their light duty vehicles. Therefore, vendors delivering construction material or hauling debris from the site during grading would use medium to heavy duty vehicles with an average fuel 41 CalEEMod User’s Guide (May 2021) states that the CalEEMod default fleet mix for worker trips includes light duty autos and light duty trucks, LDA, LDT1, LDT2, at a mix of 50%/25%/25%, respectively. 926/27/2022 Planning Commission 2 –145
